From 77da14d77f5e16c5dc24ca225b16ff77a3a3e446 Mon Sep 17 00:00:00 2001 From: Shai Almog <67850168+shai-almog@users.noreply.github.com> Date: Thu, 27 Aug 2026 09:32:00 +0300 Subject: [PATCH 001/167] Make the clean target a usable program runtime, and let casts fail The clean (non-Objective-C) target could translate a Java main() and run it, but not much more: main(String[]) was handed JAVA_NULL, so a translated program could not read its own command line, and there was no way to read the environment, open a file or read stdin. Every knob had to be a compile-time macro, which is why the GC benchmarks are parameterised the way they are. - argv reaches main(String[]) via cn1MainArgs, skipping argv[0] the way Java does - System.getenv(String) - java.io.FileInputStream / FileOutputStream over C stdio, so the same code serves the Windows target, which has no unistd.h - java.io.StandardInputStream behind System.in. Not a FileInputStream: stdin is not seekable, so skip and available cannot be answered by seeking Separately, CHECKCAST. BC_CHECKCAST expanded to nothing, so a failed cast handed the wrong object to the next instruction and the target type's fields were read out of it -- a native crash no Java catch can see (issue #5531). Implementing the macro alone would have changed nothing: BytecodeMethod DELETES the CHECKCAST instruction before codegen ("gets in the way of other optimizations"), so nothing ever reached TypeInstruction. Array stores had the companion hole -- AASTORE was bounds-checked but never covariance-checked, and the macro's own comment claimed otherwise. Both are now enforced under -Dcn1.checkedCasts=true, which also drives retention of ClassCastException and ArrayStoreException so the emission and the classes can never disagree and leave an unresolved symbol. Opt-in, because turning it on changes the outcome of app builds that succeed today; a server-side build parsing untrusted input should always enable it. Verified against vm/tests: 80 tests, no regressions.

That needed a number, so ThreadCost parks N threads and holds them while RSS is read from outside. Measured with 512 parked threads: musl/arm64 (the deployment target) 243 KB/thread macOS/arm64 118 KB/thread Attribution on Linux, by ablation: callStack arrays (1024 -> 128) -50 KB pendingHeapAllocations (4096 -> 256) -27 KB try blocks (500 -> 32) -15 KB shadow stack (16536 -> 2048) 0 KB thread stack (16MB -> 256KB) 0 KB Two of those are worth recording because they are the opposite of what the macOS numbers suggested. The shadow stack, the biggest single allocation at 258KB, costs nothing resident on Linux -- shrinking it changes the number not at all, though on macOS it looked like the dominant cost. And the pinned 16MB thread stack is free: it is reserved, never committed. The five sizes are now #ifndef-guarded so an A/B can override them with -D. They were unconditional #defines, so a -D was silently ignored -- the redefinition warning is suppressed by the generated code's -w, which is how the first round of ablations produced three identical numbers and no conclusion. The shadow stack is now mapped rather than malloc'd and memset in full. That is a spawn-path win (258KB of stores per thread creation), not a footprint win; the comment says so rather than implying the measurement it did not produce. The conclusion for the server design: at 155-243 KB even with every buffer shrunk, ten thousand connections is 1.5-2.4GB of threads. A connection cannot have one. The design is a reactor with a bounded worker pool, where a few dozen threads cost a few megabytes and the connection is just an fd.

The generated code then carried on with the statement after the throw, with the method's locals in whatever state the failed operation left them. On an app target something upstream nearly always catches -- the EDT's own try -- so this stayed invisible; a server binary has nothing above main. What it looked like in practice: a database client whose TLS handshake was rejected threw, Database.open "returned" a null, and the program segfaulted two statements later on the null. The message that would have named the real cause was never printed, and a program that threw out of main exited with status 0. The clean target now prints the exception, its message and a stack trace, and exits 1. Every other target keeps today's behaviour: making this fatal everywhere would change what apps that ship today do, so the generated main() opts in and nothing else does. Two details the fix needed. The message is fetched separately because the pre-rendered stack string carries only the type, and on a server the message is the actionable half. And the try depth is reset to zero before rendering: the search leaves it at -1, and a Java method that saves and restores a negative depth corrupts what it restores into, which turned the reporter itself into a SIGBUS. Also here, because the same audit found it: java.lang.System.in is a static field, so every translated program reaches StandardInputStream's natives, and the JavaScript backend had no category for them -- which turned the core-slice completeness gate red for code that never touches stdin. They are marked unsupported there, as java.io.File already is: a browser has no process stdin.

ATOMIC_VAR_INIT on an atomic POINTER is rejected by clang 14 -- which is what Debian bookworm ships, and therefore what the glibc backend builder image uses -- as "initializer element is not a compile-time constant". The generator emits it for every `volatile` static reference field, so any such field in ordinary user code failed to build there. A static object is zero-initialized by the language, so the initializer is dropped; the macro is deprecated in C17 and gone in C23 regardless. CN1_RESUME_THREAD referenced gcParkCaptured unconditionally, but that field only exists when conservative roots are compiled in. So -DCN1_DISABLE_CONSERVATIVE_GC_ROOTS -- the A/B arm vm/CLAUDE.md documents -- did not build at all, and the one measurement that isolates the conservative scan's cost could not be taken.

Measured round trip on arm64: 2.1ns. The runtime is three files -- cn1_virtual_thread.{h,c} and the context switch, which has to be assembly because glibc aborts a cross-stack longjmp under _FORTIFY_SOURCE and musl has no makecontext. aarch64 and x86_64 are implemented; anywhere else the header's stubs answer "there is no virtual thread here", which is the truth, and every caller folds away at compile time. The collector had to learn about them, because a virtual thread breaks two of its assumptions silently: - A carrier RUNNING a virtual thread has its stack pointer inside that virtual stack, so the [sp, base) bounds test rejected it and skipped every conservative root the thread held. - A PARKED virtual thread is referenced by nothing the collector walks, while its stack still holds Java references in C temporaries. Both are served from a registry snapshot taken once per cycle before any thread is stopped: walking the live registry would take its mutex, and a thread frozen by the stop signal may be the one holding it. Also here, because they are what made the above work: the translator emits the runtime into every generated project, and CN1_RESUME_THREAD yields a virtual thread rather than sleeping the carrier it runs on -- a carrier hosts many virtual threads, so sleeping it freezes all of them. Carried along in the same change: LinkedHashMap runs its eviction hook only on a real insertion, as java.util does, which also drops an allocation per insertion; a generated mapper can serialise straight to JSON instead of filling a map and walking it back, measured 2.05x/1.51x/2.81x on a four-property object with output asserted byte-identical; and a repeated CHECKCAST is dropped when it immediately follows the identical one.

Two things make that expensive on the backend and neither is visible at the call site. It sleeps the CARRIER, and a carrier hosts many virtual threads: hostCount is min(workers, cores), so on a two-core pin sixty four connections share two carriers. One carrier sleeping a millisecond freezes about thirty two connections that were ready to run, which is the shape of a server whose median is healthy and whose tail is not. And it is a sleep-poll, so the wait is quantised to the sleep interval however briefly the flag was actually held. The measured worst case was 1923us: two iterations of a 1ms sleep waiting for something that had long since cleared. The pacing park already yielded here; this site did not, and it is the hottest of the four -- once per syscall return, 204105 times in a twenty second run against 9 for the handshake. Platform threads still sleep, having nothing to yield to, and off the backend the stub answers "not virtual" so the macro folds back to exactly the old loop. This shortens the wait; it does not remove it.

Virtual threads were gated on a build flag that only the server build set, and the flag was justified by an Xcode misfiling it was working around: Xcode has no mapping for the .S extension, so an unrecognised one becomes `lastKnownFileType = file` and lands the file in the RESOURCES phase, where it is copied into the bundle and never assembled. The iOS target then failed to link naming _cn1VirtualThreadSwitch, whose source was sitting right there in the project. Gating the feature off made the misfiled resource inert, so the phone target linked and the misfiling stayed hidden. Fix the misfiling instead: .S maps to sourcecode.asm.asm (preprocessed, which the capability gate in the file needs) and .s to sourcecode.asm, and both route into the Sources phase rather than Resources. Every future assembly file gets this too. That removes the reason for the flag, so the gate becomes a capability test: on anywhere the switch is written for -- aarch64 and x86_64, excluding Windows, whose calling convention needs its own prologue -- virtual threads are on. There is no separate "server build" of the VM; a flag would only mean the feature is off in every build nobody remembered to set it in. Elsewhere the header's no-op stubs answer "there is no virtual thread here", which is true, so the collector needs no #ifdefs and every call folds away. CN1_DISABLE_VIRTUAL_THREADS forces that path. The predicate is repeated verbatim in the .S, which is preprocessed assembly and cannot include the header -- the two must stay identical or the link breaks on the switch symbol. Also excludes LinkedHashMap from the copyright gate: it is Apache Harmony source and keeps its Apache-2.0 notice.

Under MSVC the variable stays unset and expands to nothing. - Xcode has no mapping for .S at all, so it became `lastKnownFileType = file` and landed in the RESOURCES phase, shipped into the bundle and never built. sourcecode.asm is the identifier for both spellings: Xcode's own StandardFileTypes.xcspec lists it as `Extensions = (s)` with `GccDialectName = assembler-with-cpp`, which is the preprocessing the file's capability gate needs. The neighbouring sourcecode.asm.asm is for .asm. Tests. BackendUncaughtExceptionTest needed a support class that does not exist here, and only ever reached the fix through a server binary; replaced by UncaughtExceptionIntegrationTest, which builds a clean-target program directly and asserts the whole contract -- message, stack frame, non-zero exit, and that execution stops AT the throw rather than carrying on, which is the half the other three can all pass without. test_virtual_thread.c was built by nothing. A hand-written context switch with no enforced coverage could break in any commit and stay green, so VirtualThreadRuntimeTest drives it from the suite, compiled out of the SAME staged classpath resources a generated project receives -- which also asserts those three files are present and agree with each other. The iOS project test now asserts the assembly is typed as assembly, IS in the Sources phase and is NOT in Resources. All three: the type alone does not prove the phase, and the phase alone does not prove it assembles. The generator's own source set is what caught the last of it. Two copies of replaceLibraryWithExecutableTarget matched the add_library line by its full argument LIST -- the shared one in CleanTargetIntegrationTest and a private duplicate at the bottom of FileClassIntegrationTest. Adding the assembly glob made both stop matching, so those tests built a library and then failed running an executable nothing had asked for. The shared one now matches the CALL and asserts the substitution happened; the duplicate is gone, and FileClassIntegration uses the shared one like the other twenty-two callers already did.

Taken together they are one theme: a virtual thread is a mutator the collector cannot see by the usual means, and the code that creates one was doing only half the job. RUNNING VIRTUAL THREADS LOOKED PARKED. cn1SpawnVirtualThread builds its VM state with bindToCallingOsThread false, which leaves threadActive FALSE, and nothing ever raised it. A collection running concurrently therefore treated a mutator executing Java as parked, and was free to scan or migrate its object stack and pending-allocation table underneath it -- missed roots at best, corruption at worst. The flag now moves with the context switch, up on resume and down on suspend, because a SUSPENDED virtual thread genuinely is parked: the collector reaches its roots through the registry snapshot instead. The transition is a weak symbol with a no-op default, not a function pointer. cn1_virtual_thread.c cannot include cn1_globals.h (the standalone runtime test builds it with no VM at all), an indirect call on a path whose entire value is that it costs 2.1ns is not free, and a weak symbol costs a direct call the linker resolves to the VM's real one when there is a VM. NOTHING RELEASED THE STATE. cn1VirtualThreadFree knows only about the coroutine. The VM state spawned beside it holds a 264KB shadow stack, the call-stack arrays, the pending-allocation table, and one of the NUMBER_OF_SUPPORTED_THREADS slots in allThreads. A virtual thread per request would have consumed a slot per completed request and eventually tripped CODENAME_ONE_ASSERT(threadOffset > -1). Added cn1RetireVirtualThread, which marks the state dead the way an OS thread's death does and then frees it with the same gcQueuedForDrain deferral the Java finalizer uses. THE UNCAUGHT-EXCEPTION EXIT WAS NOT GATED. This is the one that would have shipped. The generated main() is emitted for every target that has one, iOS and macOS included, and cn1AbortOnUncaughtException was set unconditionally -- so an uncaught exception on any thread would have terminated a shipped app. The comment sitting above it claimed the opposite ("Only this target opts in, so nothing that ships today changes behaviour"), which was simply false: the enclosing guard is `if(m.isMain())` and nothing more. Now gated on OUTPUT_TYPE_CLEAN. BLOCKING STDIN NEVER PARKED THE MUTATOR. System.in.read() waits as long as nobody types, with the thread left active, so a concurrent collection spun for a safepoint that could not arrive until a human pressed a key. Bracketed with CN1_YIELD_THREAD/CN1_RESUME_THREAD like the socket reads -- which then needs the keep-alive those reads also need, because only an interior pointer into the array is live across the call and the collector would otherwise sweep the buffer being filled. Portable here (a volatile store) rather than the Linux port's asm barrier, because this file also compiles under clang-cl. feof is read before the resume for the same reason errno is: the resume is a safepoint, and anything asked afterwards describes the wait. THE SHADOW STACK WAS FREED THE WRONG WAY. cn1AllocThreadStack falls back to calloc when mmap is out of MAPPINGS rather than out of memory, and cn1FreeThreadStack always called munmap. That fails with EINVAL and leaks the whole stack -- or, on an allocator that returns page-aligned blocks, unmaps memory the allocator still believes it owns. Which allocator answered is now recorded and the free is paired to it.

Two fields did not, so a mapper changed its wire representation on the day it gained a direct writer: - A null List serialised as `null`, where the map path emits `[]` -- emitFieldToMap builds its ArrayList unconditionally and fills it only when the source is non-null. - Enum elements went through toString(). The map path uses Enum.name(), and deserialisation matches against the declared constants, so an enum that overrides toString() produced JSON that could not be read back at all. Every other element kind was checked rather than assumed: appendJsonValue already maps Date to getTime(), scalars and collections through writeJson, and a mapped object through its own mapper -- the same three answers emitFieldToMap gives. Nothing was comparing the two paths, which is why both got through. Every existing test exercises one route or the other, never one against the other, so the divergence was invisible to all of them. directJsonMatchesTheMapPathExactly runs an object with a populated list, an enum list, a Date and scalars, and then the same class with every list left null, asserting the two routes produce identical text. It asserts equality of the paths rather than against a literal on purpose: it keeps holding when a field kind is added, with nobody remembering to extend a hand-written expectation. Two things that test needed before it proved anything. It drives the generated mapper's own toJson rather than Mappers.appendJson, which goes through the registry -- unpopulated in an isolated classloader, so it fell back to toString() and compared the map path against "com.example.Swatch@23706db8". And it asserts the mapper actually implements Mapper.Direct, without which it would compare the map path with itself and pass while testing nothing. The test enum deliberately overrides toString() to disagree with name(), so the wrong choice cannot pass. Also drops a redundant `public` on the interface: PMD's UnnecessaryModifier, and a zero-findings gate.

EVERY cn1lib NATIVE CHECK STOPPED AT A MISSING HEADER. cn1_globals.h now includes cn1_virtual_thread.h -- CN1_RESUME_THREAD yields a virtual thread rather than sleeping the carrier it runs on -- and two places stage the port headers into a scratch directory to compile a cn1lib against them. Neither knew about the second file, so both stopped at "'cn1_virtual_thread.h' file not found" before compiling a line: the six ad-cn1lib xcodebuild probes and check-cn1lib-native-sources.py. The workflow's path filters gain the header too, otherwise a future change to it skips the very check that would catch this. java.io.File HAD NO WINDOWS PATH. Its non-ObjC arm is POSIX-only -- unistd.h, dirent.h, access(), X_OK -- and Windows reaches that arm under clang-cl, which is neither __OBJC__ nor POSIX. It went unnoticed because java_io_File_runtime.c is emitted only when an app actually uses java.io.File, and until the clean target became a usable program runtime no Windows build ever did. Now every one of them failed on 'unistd.h' file not found. The Win32 arm: io.h and direct.h for _access, the access-mode constants the MSVC CRT does not define, and FindFirstFile for the directory walk, in the same two-pass shape as the POSIX one (count, allocate, refill) because allocArray can collect and the array must not be built with a find handle open. X_OK maps to an existence check: Win32's access model has no execute bit, and _access REJECTS a mode of 1 rather than answering "not executable". isHidden asks for FILE_ATTRIBUTE_HIDDEN instead of guessing from a leading dot, which means nothing on Windows. Everything else -- stat, remove, rename, mkdir -- the CRT already provides under the same names. Also merges two identical project() branches that SpotBugs flagged as DB_DUPLICATE_BRANCHES: Linux and the clean target answer the assembly question the same way, so they share one branch instead of two spelled alike. The POSIX arm is verified here (FileClassIntegrationTest, 5/5); the Win32 arm can only be verified by CI, which is what reported it.

Both callers unpack a DOWNLOADED zip -- Groovy for the console, JavaFX for the browser component -- so the archive is not something the user authored, and the consequence is an arbitrary file overwritten under their account while they believe they are unpacking a dependency. CWE-22. Every entry now has to resolve inside the destination or it is refused. The comparison is between CANONICAL paths -- resolving the ".." is the whole point -- and it uses java.nio.file.Path.startsWith rather than String.startsWith, for two reasons. Path compares COMPONENT-wise, so a sibling like "/tmp/dest-evil" is rejected against "/tmp/dest" where a character-wise prefix accepts it, and giving the string prefix a trailing separator to fix that then wrongly rejects the destination directory itself. It is also the shape CodeQL recognises as a sanitizer: the first attempt here was a correct canonical-path check that the query still flagged, because a compound `!a && !b` guard did not read as a barrier. Two things the fix had to bring with it, both found by writing the test: - Parent directories are created before extracting. FileOutputStream will not create them, and a nested entry can arrive before the directory entry that holds it, so "nested/deep/leaf.txt" in an archive that declares no directory entries threw FileNotFoundException. That was broken before this change too. - destDir uses mkdirs rather than mkdir, so a destination more than one level deep is actually created. Both streams are closed in a finally, which they were not: an IOException mid-extract leaked the descriptor. The test builds the malicious archive rather than checking one in -- a committed zip that escapes its destination is an awkward thing to keep in a repository, and building it puts the attack in front of the reader. Verified non-vacuous by reverting the fix: 2 failures against the old code, 0 against the new.

WIN32_LEAN_AND_MEAN keeps winsock out, and nothing here wants it. - S_ISDIR / S_ISREG undeclared. The CRT has the st_mode BITS but not the macros that test them, so they are defined from _S_IFMT/_S_IFDIR/_S_IFREG. - PATH_MAX undeclared -- MAX_PATH is the Win32 spelling. - realpath undeclared. _fullpath is the equivalent, but it takes (destination, source), the REVERSE of realpath's (source, destination), so the macro swaps them. Getting that backwards compiles and canonicalizes the wrong string in silence. It also resolves a path that does not exist rather than failing, which is the more useful answer for getCanonicalPath. The POSIX arm is unchanged and still verified here (FileClassIntegrationTest, 5/5). The Windows arm is verified only by CI, which is what reported both rounds.

Moved onto the arm that uses it. Swept the rest of this branch's additions for the same class of thing rather than waiting for CI to find them one at a time: every other POSIX call in code Windows compiles is either guarded (mmap/munmap behind !_WIN32, pthread_attr_setstacksize behind __linux__) or shimmed in cn1_win_compat.h (usleep, pthread_key_create, pthread_getspecific). The virtual-thread runtime -- including the __attribute__((weak)) definition, which clang-cl treats differently on COFF -- is entirely inside the CN1_VIRTUAL_THREADS gate, which excludes _WIN32, so none of it is compiled there at all.

It does -- but only once the carrier's stack pointer is actually INSIDE the virtual stack, and `running` is raised before the switch and lowered after the switch back. In those two windows a stopped carrier still has an OS-stack pointer, so cn1VirtualThreadForStackAddress matches nothing, the carrier pass scans only the OS stack, and this pass skipped the virtual stack for being "running". References held in C temporaries there could be swept. The flag cannot be made atomic with the switch it brackets, because the switch is what changes the stack the flag would have to be written from. So the passes now OVERLAP instead of partitioning: every virtual thread's saved region is scanned unconditionally. Safe, because [sp, stackHigh) is inside the mapping whenever sp is non-zero; complete, because while a virtual thread runs the carrier's pointer is lower, so this pass covers a subset and the carrier covers the rest; and cheap, because conservative marking is idempotent. cn1RetireVirtualThread's "use after free" was NOT one, and the code now says so. markDeadThread -> collectThreadResources sets gcQueuedForDrain unconditionally and has no early return, so the synchronous release branch was unreachable. It read as live, though, so it is gone and the invariant is written down -- including the reason it matters, which the report had right: codenameOneGCMark copies each ThreadLocalData* out of allThreads under the critical section and dereferences it OUTSIDE the lock, so a synchronous free would be a genuine use-after-free. File.list returned something that called itself a String. All three arms passed the ELEMENT class to allocArray, which installs whatever it is given as the array object's own class; cn1MainArgs has always passed class_array1__java_lang_String. Pre-existing on iOS and Linux, copied into the new Windows arm, fixed on all three. Windows absolute paths were treated as relative, which corrupted them rather than merely misreporting them: getAbsolutePathImpl tested p[0] == '/', so "C:\data" had the working directory prepended. There is now a per-platform predicate that knows about drive letters and UNC roots. The matching Java-side gap is deliberately left and documented at the predicate: File.isAbsolute() tests startsWith(File.separator) and separator is "/" everywhere, which needs a per-platform separator in shared JavaAPI -- a change for every port, not for making the clean target build. Blocking file reads and writes now park the mutator, like the socket reads and StandardInputStream already did: a FIFO, a device or a network-backed path blocks for as long as the far end stays quiet, and an active thread there strands the collector waiting for a safepoint that cannot arrive. Both carry the buffer keep-alive for the same reason those do -- only an interior pointer is live across the call. (Moving that macro above its first use is why it now sits at the top of the file layer rather than beside stdin.) The benchmark helper compiles the emitted .S. Third place with this bug: the CMake generator and the Xcode project generator had it too, and a *.c-only invocation links against a missing cn1VirtualThreadSwitch on any target where the switch exists. Two findings are recorded in the file rather than fixed, with the analysis and the actual remedy: 32-bit ftell/fseek cannot express a position past 2GiB where C long is 32 bits, and paths reach the narrow CRT as UTF-8 and are read as ANSI. Both are pre-existing on every platform, both want a change across the whole file layer, and neither is what enabling the clean target is about.

Each of these was the direct path being reasonable in a way emitFieldToMap is not, which is the same thing as changing a mapper's wire format the day it gains a direct writer. - A property NAME was escaped for the Java literal and not for JSON. escape() doubles a quote so the generated source compiles; the resulting writer then appended the raw character, so a @JsonProperty holding a quote emitted "a"b" -- unparseable. The map path never had this because JSONWriter puts the key through writeString. Now jsonEscape composed with escape: one makes the JSON valid, the other makes the source compile. Done at generation time, since a jsonName is a compile-time constant and the writer should stay a literal append. - A Property value was rendered too well. emitFieldToMap stores it RAW, so JSONWriter renders a Date or a mapped object through String.valueOf; appendJsonValue turned them into epoch millis and nested JSON. New Mappers.appendJsonRaw is exactly JSONWriter's answer for a value that was put in the map unchanged. - A reference field looked its mapper up by RUNTIME class. A field declared as a mapped base holding an unmapped subclass therefore found nothing and fell back to a quoted toString, where the map path asks Mappers.get(Declared.class) and serialises it as an object. New Mappers.appendJsonUsing takes the mapper the caller names, and still uses that mapper's direct route when it has one. - Mapped list ELEMENTS had the same problem, plus the general one behind it: the direct path had a two-way branch where emitFieldToMap has four. It now mirrors them one for one -- enum name(), scalar raw, Date getTime(), everything else through the declared element type's mapper. The test was the actual defect. Nothing compared the two paths against each other, which is why all of this shipped; and the parity test added for the first pair needed three fixes of its own before it proved anything: - It went through Mappers.appendJson, which consults the registry. In an isolated classloader the registry is empty, so it compared the map path against "com.example.Swatch@23706db8". It now drives the generated writer. - The polymorphic case had no mapper registered for the base type, so BOTH paths fell back to toString and agreed. Registering it is what makes the two implementations able to differ at all. - assertEquals reports the FIRST difference, so one unfixed case masked the others. Each representation is now pinned individually, which also catches the case equality cannot: both paths wrong in the same way. Verified by reverting the generator with the test in place: one failure against the old code, six passing against the new.

Once any byte has been read that addition overflows signed long -- undefined behaviour, and in practice a wrap to negative, so the seek goes BACKWARDS and the caller is told it skipped a negative distance or gets an error where it should have landed on EOF. It now clamps against the remaining DISTANCE, which cannot overflow: end is at least start, and start plus the clamped amount is at most end. File.list walked the directory TWICE -- count, allocate, walk again -- and assumed both walks saw the same directory. They do not. A file created in between overruns the array, and CN1_SET_ARRAY_ELEMENT_OBJECT turns that into ArrayIndexOutOfBoundsException; a file removed leaves trailing nulls in a String[] that no caller expects. Directories change under readers routinely, so this was never sound. I wrote the Windows arm that way deliberately, mirroring the POSIX one, which means I copied the structure without asking whether it held. Both arms now enumerate ONCE into a small growable list of names and build the array afterwards. The names are held in C memory on purpose: allocArray and newStringFromCString can both collect, and nothing may hold a directory handle across that. The ObjC arm is left alone -- NSFileManager hands back a snapshot, so it never had the race. Also moves stdlib.h to the shared include group, since the list uses malloc/realloc/free on both arms and sits outside the platform blocks. The test is the part worth reading. FileClassIntegrationTest never called File.list(), so the native listing was COMPILED but never RUN by any suite: the rewrite above passed 5/5 while executing none of it, and reverting it would have passed too. Coverage now creates a directory, lists it, and pins the three things that were wrong or fragile -- the entries, the absence of nulls, and that the result is a String[] rather than a String, which is the pre-existing allocArray class bug nothing had ever asserted. Confirmed the assertions discriminate rather than merely execute: with the array class reverted to the element class, all five configurations FAIL; restored, all five pass.

The predicate knew about a case the code after it did not. _getdcwd asks the right drive. Deliberately not _fullpath, which the report suggested: it also normalises "..", and getAbsolutePath is specified NOT to do that -- resolving is getCanonicalPath's job. Using it would have swapped a wrong path for a subtly wrong contract. createNewFile was check-then-act: access(), then fopen(p, "w"). Losing that race does not merely return the wrong answer, it TRUNCATES the file the other process just created, and then reports true as though it had done the creating -- which is exactly the failure mode the lock-file and single-instance patterns it exists for cannot survive. Now a single O_EXCL open on both arms, with the kernel deciding. Pre-existing on POSIX too, so both are fixed. ON THE TEST, because the distinction matters: the coverage added here is a REGRESSION GUARD, not a demonstration of atomicity. It checks the uncontended path -- createNewFile on an existing file returns false and leaves it intact -- and the old check-then-act version passes it too, because access() succeeds and it returns before reaching the truncating fopen. Confirmed by running the suite against the old implementation: 5/5 green. The real defect needs a file to appear between the check and the open, which one thread cannot arrange, so the argument for the fix is structural rather than empirical and the comment in the test says so.

That is correct for what it exists to serve -- generated string literals, which are ASCII plus ~~uXXXX escapes -- and wrong for anything arriving from outside the program. A UTF-8 "e-acute" is two bytes, so main(String[]) and System.getenv handed back one garbage char per byte, corrupting paths and option values before the program had a chance to look at them. Both entry points are new in this branch. newStringFromUtf8 decodes properly: multi-byte sequences, surrogate pairs for astral code points, and U+FFFD for malformed input the way java.lang.String's own decoder does -- a program should not die because one environment variable holds a stray byte. Overlong forms, UTF-8-encoded surrogates and out-of-range code points are all rejected. newStringFromCString itself is deliberately NOT changed. Every native-to-Java string in the VM goes through it, its byte-widening is load-bearing for the literals it serves, and its own comment records that the high-bit path is bit-identical to what came before. Correcting the two entry points this branch added is the scoped fix; the general version is the same work as the ANSI-versus- UTF-8 path issue already recorded in nativeMethods.m. TWO BUGS UNDERNEATH, both found by the test rather than by reading: newString was broken and had never been called from C. JAVA_CHAR is an int and JAVA_ARRAY_CHAR is an unsigned short, and it sized the allocation with sizeof(JAVA_CHAR) while memcpy'ing length * sizeof(JAVA_ARRAY_CHAR) bytes out of a four-byte-element array -- half the input, at the wrong stride. My decoder was its first caller and hit it immediately: "cafe" came back as c,NUL,a,NUL,f. It now narrows element by element. Behind that, the representation is not a free choice. A string whose units all fit in a byte is stored as a COMPACT byte[], anything else as a char[], and charAt reads whichever it finds -- so handing it the wrong one reads 8-bit units out of 16-bit data and produces exactly the same symptom rather than failing. That rule now lives in cn1StringFromUnits, used by newString and newStringFromUtf8. newStringFromCString keeps its own copy on purpose: it tracks the Latin-1 flag during decoding and runs for every literal at startup, so routing it through a helper that recomputes would add a pass over every literal in the program to save a dozen lines. The comment says so, and says the two must change together. The test reports CODE POINTS rather than text, so it cannot pass through a console-encoding coincidence: "cafe-acute-euro" must arrive as 99,97,102,233,8364, which covers a two-byte and a three-byte sequence. Byte-widening reports the individual bytes instead, which is how the newString bug surfaced.

Marking the attached ThreadLocalData threadActive around the context switch reads as obviously correct and is a REGRESSION, worse than what it fixed. A virtual thread's state has no pthread of its own -- deliberately, it may run on a different carrier next time. The collector's wait for a lightweight thread is `while(t->threadActive) usleep(500)` with no bound, and the forced-stop escalation that exists to break exactly that wait is gated on gcPthreadValid, which is permanently false here. So the flag converts a POSSIBLE race on the state's object stack into a CERTAIN hang for any virtual thread that computes without reaching a safepoint: the collector waits for a flag only that thread can clear, and cannot stop it. What the same report asked for has two halves, and the other one stands. The C stack is covered: cn1GcScanParkedVirtualThreads scans every registered virtual thread whether or not it is running, so no virtual stack goes unscanned during the windows where `running` is set but the carrier has not switched yet. That fix is independent of this revert and stays. The half that remains open -- a collection walking the state's object stack and pending-allocation table while the virtual thread mutates them -- is documented at cn1SpawnVirtualThread along with why the obvious fix is worse and what the real one is: carrier association. A running virtual thread executes ON a carrier that does have a stoppable pthread, so the collector should satisfy the wait by stopping the carrier. That needs the stop handshake to stop being per-TLD (the signal handler records into the TLD of the thread it runs on, which is the carrier's), i.e. a change to the collector's stop protocol rather than to the spawn path -- not something to improvise in an API that has no callers yet.

A generated array class records arrayType as the BASE element class rather than the immediate component: String[][] has dimensions 2 and arrayType String, not String[]. So `values[0] = new String[1]` asked whether a String[] is an instance of String, got no, and threw ArrayStoreException on a store the language requires to succeed. Restricted to dimensions == 1, where arrayType genuinely IS the component type. Multidimensional stores lose a diagnostic that did not exist before this feature was added; the alternative was breaking working code. Covering them properly needs the immediate component type, either emitted per array class or reconstructed from dimensions at runtime, and the macro says so. Also fixes a timeout in VirtualThreadRuntimeTest that could never fire.

"A thread it cannot stop is one it does not scan either way" is true only while the thread genuinely cannot be stopped. Failures are often TRANSIENT -- a stop signal briefly masked is enough -- and the thread recovers. Skipping it then meant cn1GcScanThreadNativeStack returned without scanning a RESPONSIVE thread, for roughly the next sixty collections, so references held only in frameless C locals or registers went unmarked and could be reclaimed while still in use. A GC correctness bug, traded for a performance win. The two things I had conflated: the cost was never the SIGNAL, it was the WAIT. One unresponsive thread consumed the entire 2,000,000-spin budget -- 267ms of a 280ms mark. So a thread with a failure history is now probed with a 20,000-spin budget rather than skipped. Healthy threads answer within about 200 spins, which is a hundredfold margin for one that is merely slow, at one percent of what a hang used to cost; and a thread that recovers is picked up on the very next cycle instead of up to 64 later. Verified across the GC suites, including GcUncooperativeThreadIntegrationTest -- the issue #5537 scenario this logic exists to serve: 6/6.

The map path stores the value and lets JSONWriter see the null, emitting JSON null for both. Told apart by binaryName, which does distinguish them, with a temporary in each so a getter is not evaluated twice, and charValue() so String.valueOf resolves to the char overload rather than the Object one. The parity test carries both fields now, and they discriminate by construction: against the old code the Boolean case throws (a test error) and the Character case produces a quoted "null" against the map path's null (an assertion mismatch).

It returns 0 now, and cn1SpawnVirtualThread already checks for that. Pre-existing rather than new: every OS thread creation runs this path too. A virtual thread per request only makes reaching the limit realistic. The partially built state is unwound through cn1FreeThreadLocalDataFields, extracted from cn1ReleaseThreadLocalData rather than copied, because the release path also decrements nThreadsToKill and a state that never reached allThreads was never counted as living. Duplicating the frees would have drifted apart, and getting that counter wrong would have been a slow leak in the opposite direction.

THE HANG I REVERTED WAS STILL REACHABLE. Removing the threadActive assignment from cn1VirtualThreadResume did not close it, because CN1_RESUME_THREAD does the same thing and every bracketed native goes through that macro. getThreadLocalData() resolves to the VIRTUAL thread's state while one is running, so a virtual thread that read a file or a socket returned with its state marked active, and nothing lowers it again until the next yield. Same unbounded while(threadActive) wait, same forced-stop escalation gated on gcPthreadValid and therefore unavailable, same stall. I checked the call site I had edited and not the shared path through it. The guard states the invariant the code always needed: mark active only what the collector can STOP. gcPthreadValid is exactly that question. A real thread is unaffected; a virtual thread's state stays down, which is where it was before any of this. Roots do not depend on the flag -- cn1GcScanParkedVirtualThreads scans every registered virtual thread whether or not it is running. THE EXHAUSTION CHECK INTRODUCED A USE-AFTER-FREE. pthread_setspecific binds the new state to TLS above the capacity search, so the failure path I added freed a state the key still pointed at: every later getThreadLocalData() on that thread would return memory that had been given back. That is worse than the out-of-bounds write it replaced, because the thread keeps using the stale pointer rather than failing. Unbound before the free. Also: System.getenv(null) throws NullPointerException as the API requires, instead of returning null and making an invalid argument indistinguishable from an unset variable.

Reads after close now throw. The flag is volatile because a stream is usually closed from a different thread than the one blocked reading it. The file descriptor is deliberately NOT closed, which is a departure from what the report suggested and the reasoning is in the code. Descriptor 0 belongs to the PROCESS rather than to this object: the VM and any native library in it may still be using it, and once released the number is free for the next open() in the process to take -- so a later read would be answered by an unrelated file instead of failing. That is a worse outcome than the bug being fixed. Closing the stream stops this stream, which is what the caller asked for. The test drives a real clean-target binary, because the behaviour only exists once the native read is wired up, and it discriminates by construction: without the fix stdin is empty, the read returns -1, and the program prints CLOSE_NOT_HONOURED.

Saying so in the code is the answer to that, not another round of patches. CHECKED CASTS STAY OFF, INCLUDING ON THE CLEAN TARGET. Review observed that nothing sets -Dcn1.checkedCasts=true and proposed defaulting it on for clean builds. Inert is the intent: the feature is unfinished, and enabling it would change codegen for every clean-target build in the tree to exercise a path still being designed. The flag stays the way in. The emitted checks are maintained under it -- the null guard, the JLS ordering, the one-dimension restriction -- but their presence is not a claim that the VM validates casts today, and CLAUDE.md's "never rely on ClassCastException" remains the rule for every shipping target. A comment that claimed builds pass the flag is corrected; none do. cn1SpawnVirtualThread AND cn1RetireVirtualThread ARE EXPERIMENTAL. Nothing in this repository calls them; they ship so the server work can build against them. Their three known gaps are named at the definition -- a collection can walk the state's object stack while the virtual thread mutates it, retiring one retires the CARRIER's BiBOP pages, and the collector cannot stop a compute-only virtual thread -- and all three wait on the same design decision: carrier association, which means the stop handshake giving up being per-TLD. Findings there are noted, not patched, because every patch so far traded one hole for another: a scanning race became a collector hang, a bounds fix became a use-after-free. The line is drawn explicitly in both notes. The COROUTINE runtime underneath -- cn1_virtual_thread.{h,c,S} and the collector's stack scanning -- is finished, tested, exercised by VirtualThreadRuntimeTest, and is NOT experimental.

Raised in review as a P1; it is real, and it belongs to the EXPERIMENTAL spawn API rather than to the scan. Inside the VM the only caller of cn1VirtualThreadCreate is cn1SpawnVirtualThread, which nothing in this repository calls -- the other callers are the standalone runtime test, which has no collector. Not widened here, and the reason is in the code: covering post-snapshot registrations from this pass means holding the registry lock during the scan, and avoiding exactly that is what the snapshot is FOR -- a thread frozen by the stop signal may be the one holding that lock. The suggested remedy trades an unreachable missed root for a reachable deadlock. Listed as the fourth known gap above cn1SpawnVirtualThread. All four resolve together through carrier association, when there is a caller to design against.

It reports success when the destination already exists and failure when it does not, and never moves the source. Not merely aliasing either: the helper frees and re-allocates when the second string is longer, so the first pointer can be dangling rather than stale. Two corrections to how this was reported. It is not Windows-specific -- the shared non-ObjC arm serves Linux and the clean target too -- and renameTo on the clean target has therefore been entirely non-functional rather than degraded. The source is copied out before the second conversion now. Swept before fixing: this is the ONLY function in java_io_File.m, nativeMethods.m or cn1_globals.m that converts two strings in one call, so the fix is local, and that is from a check rather than an assumption. It survived because renameTo had no test at all -- grep found zero references in the suite. The coverage added here asserts the source is gone, the destination exists, AND that the three bytes moved; content is the assertion that discriminates, since the aliased version reported success while moving nothing. The destination name is deliberately longer than the source, which is the case that makes the buffer reallocate and the pointer dangle rather than merely alias. Verified by reverting: 5/5 fail against the aliased version, 5/5 pass with the fix.

It is wrong for a list ELEMENT, where emitFieldToMap stores _e unchanged and the writer keeps its JSON type -- so a List holding 5 serialised as ["5"] instead of [5]. Two paths with different map-path semantics, one rule applied to both through a shared helper. The generated list code now splits the no-mapper case explicitly and keeps the declared-type lookup for the rest.

A SINGLE LEADING SEPARATOR IS NOT ABSOLUTE ON WINDOWS. "\logs\app.txt" is rooted but still drive-relative -- it means that path on whichever drive is current -- and only "\\server\share" is fully absolute. Reporting the first as absolute made getAbsolutePathImpl hand it back unqualified. It is now qualified with the current drive, rather than joined to the whole working directory, which would have produced "C:\cwd\logs\app.txt". CLOSING TWICE IS NO LONGER FATAL. Two threads could both read closed == false and pass the same FILE* to fclose, which is undefined and takes the process down rather than returning an error. volatile plus a synchronized close makes it idempotent, and the finalizer takes the same lock -- otherwise the finalizer IS the second closer. What that does NOT do, stated in the code so it is not mistaken for more: a read racing a close on the same stream can still reach the native call with a handle being closed. The JDK buys that with a lock on every operation, and these streams are not worth that on every read; like most java.io streams they are for one thread at a time. The guarantee is that closing twice or closing from another thread is safe, not that concurrent use is. THE SNAPSHOT CAP IS LISTED, NOT FIXED. Past 4096 registered virtual threads the collector's snapshot truncates and the overflow goes unscanned. Reaching that count requires cn1SpawnVirtualThread, which nothing calls -- so it joins the other known gaps above that function rather than turning into collector surgery for an unreachable case. It is the second P1 raised against code that only the EXPERIMENTAL API can reach.

Sweeping the file layer found five unparked blocking calls rather than one, and the two I would not have thought of are the opens. - fflush pushes the buffer at the peer and blocks exactly where the write does. - Both fclose calls FLUSH before closing, so they block in the same place. - Both fopen calls block on a FIFO: opening for read waits until a writer opens the other end, opening for write waits for a reader, and there may never be one. Opening reads as cheap, which is precisely why it was missed. Each left the VM thread active while it blocked, so a collection waited for a safepoint that could not arrive -- and on Windows, where CN1_GC_CAN_FORCE_STOP is off, there is no escalation to break that wait. The opens need no buffer keep-alive, unlike the reads and writes: `path` points into the thread's utf8Buffer, which is C memory a collection cannot move or reclaim, whereas those hold an interior pointer into a Java array the collector could sweep. Verified by re-running the same sweep afterwards: all eight java_io_* natives that touch stdio now park.

THE EMBEDDED NUL IS REAL. The native converts to a C string, where a NUL ends it, so a lookup of "PATH" + NUL + "suffix" found PATH and returned that variable's value. A silent answer about a DIFFERENT variable is worse than reporting the name unset, so a name containing a NUL is now answered null. The check is in Java because that is where the information is: one indexOf against re-deriving the byte length in C and walking the string's backing representation, which is the compact byte[] versus char[] distinction consolidated earlier in this branch. That moved the null check up too, so the native is now the raw lookup. ILLEGALARGUMENTEXCEPTION IS DECLINED. Neither this VM's contract for getenv ("or null when it is not set") nor java.lang.System.getenv(String) declares it -- the documented exceptions are NullPointerException and SecurityException. The validation that throws IllegalArgumentException belongs to ProcessBuilder's environment mutation, not to a lookup. An empty name, or one containing '=', names nothing, and null is exactly what "not set" means. Adding the throw would make this VM diverge from the platform in the name of matching it. Written at the method so it is not re-raised. The rename to getenvImpl is the dangerous part of this edit -- a wrong native name compiles, links, and silently drops the method, leaving a green build and an inert feature. check-native-signatures.sh reports 0 fatal with every native resolving on both ports, and the UTF-8 environment test passes end to end, which it could not if the symbol had been dropped.

From 4729deac53152b83fe66f8b84adea05533b0bf25 Mon Sep 17 00:00:00 2001 From: Shai Almog <67850168+shai-almog@users.noreply.github.com> Date: Wed, 2 Sep 2026 18:15:25 +0300 Subject: [PATCH 042/167] Park the seeks too, and let the thread benchmark exit TWO THINGS, and the first is a correction to my own sweep. Last round I said every java_io_* native touching stdio now parks, and verified it mechanically -- against a pattern list I had built from the calls I had already fixed. It did not include ftell or fseek, so skipImpl and availableImpl were still unparked. A mechanical check is only as good as the pattern given to it. Seeking is not free everywhere: a remote mount or a FUSE filesystem services ftell/fseek over the wire, and the thread sits inside the CRT for the duration -- where a collection waits for a safepoint that cannot arrive, with no forced-stop escalation on Windows to break it. Both functions take ONE yield spanning their whole seek sequence rather than bracketing each call: the collector only needs the thread parked, and three yield/resume pairs would cost more than the seeks they guard. Re-swept with ftell/fseek included: zero unparked. THE THREAD BENCHMARK NEVER TERMINATED. ThreadCost spawns non-daemon threads parked on LOCK.wait() and nothing ever notified them, so returning from main ended only the main thread. The documented "/usr/bin/time -l /tmp/threadcost" invocation could not print its result without an external kill -- the measurement was taken and then discarded. It notifies after measuring; waking the workers cannot affect a number already recorded.

That is why `RestServerAnnotationProcessor` now emits +`toJson(T, ByteSink)` beside `toMap` -- it knows every field name and type at +build time, so the names go in as pre-escaped literals and each value takes the +writer its static type selects. + +Caveat on the 29%: this arm reuses a static writer, while the generated code +allocates one small wrapper per response. That is one object against a map plus +an entry per field, so most of the win should survive, but the shipped figure will +be somewhat lower and has not been measured through an annotated endpoint yet. + +### How it moved + +| /plaintext, 16 conns | req/s | p50 | p99 | bytes allocated/req | +| --- | --- | --- | --- | --- | +| starting point | 24,012 | 303 us | 342 ms | 4,786 | +| + poller no longer re-armed per request | 29,279 | 127 us | 414 ms | 4,786 | +| + collector answering its demand signal (master #5609) | 48,875 | 127 us | 212 ms | 4,786 | +| + response built as bytes, no String/StringBuilder | 84,750 | - | - | 2,948 | +| + request parsed in place, no header Map or Strings | ~250,000 | 43 us | 5.8 ms | 432 | +| + JSON serialised into a reused byte sink | 259,417 | 45 us | 25.3 ms | **176** | + +**Each row is a single sample, and the harness spread is 28-45% (see the caveats +at the end), so read this table by step size rather than by the numbers.** The +first step (24,012 to 29,279, +22%) is INSIDE the noise and is not evidence of +anything on its own; it is kept because the syscall census independently showed +the per-request `epoll_ctl`/`fcntl`/`futex` traffic going to zero, which is a +count rather than a timing and does not move run to run. The later steps +(48,875 to 84,750 to ~250,000, +73% then +195%) are far outside the noise and +are real. The last row is within noise of the one above it. + +The **allocation** column is the trustworthy half of this table throughout: those +are exact counts from the census, not sampled timings, and they are what the +rest of this file's conclusions rest on. + +Allocation per request fell **27-fold**, and that -- not any change to the +collector -- is what moved throughput and the tail together. + +## The bug that made an earlier version of this table wrong + +An earlier revision reported 302k req/s at 16 connections and ~276k at 64. Those +numbers were not reproducible, and the reason matters more than the numbers. + +The keep-alive linger (below) let a worker hold a connection and wait for the +next request instead of handing the descriptor back to the reactor. It had a +timeout but **no bound on the number of requests served in one visit**. A client +that keeps sending is readable every time, so the worker went round again +forever. With 16 workers, **16 connections were served at full speed and every +other connection starved** -- including newly accepted ones. + +It is invisible in a throughput number. `wrk` reported 234k req/s and no socket +errors while a `curl` issued during that same run **received nothing in five +seconds**. The h2 path's own comment had warned about exactly this shape +("pinning a worker to each would mean the pool size is the limit on concurrent +clients"); the h1 path did it anyway. + +Two lessons are now enforced in code rather than remembered: + +- A worker hands the connection back when something is waiting **and** there are + not enough idle workers for it. Testing the idle count alone is wrong in the + commonest configuration of all -- with connections == workers, `idle <= pending` + reads `0 <= 0` and hands back on every request, undoing the optimisation. +- `SelfTest.fairness()` saturates a 2-worker server with 4 relentless connections + and requires a fresh connection to be answered. With the guard removed it fails + with "no response in 5s"; with it, it passes -- on both the JavaSE and the + translated runtime. + +## Workers: a bounded pool, not one per connection + +Go net/http runs a goroutine per connection, so matching workers to connections +sounds like the equivalent arrangement. It is not. Every thread's stack is walked +every GC cycle, so threads are not free here the way goroutines are -- though what +exactly that walk costs is an open question (see below); the numbers are what +stand. + +| /plaintext, 256 conns | workers | req/s | p99 | +| --- | --- | --- | --- | +| one worker per connection | 256 | 45,171 | 364.7 ms | +| bounded pool | 64 | **237,198** | 72.5 ms | +| bounded pool | 32 | 216,100 | 55.6 ms | + +At 256 workers `/json` collapses to 11,101 req/s. + +**64 is not a magic number, and it is not the core count either.** Both were +worth ruling out, because every reading above came from one machine with the +server pinned to two cores -- where "64 workers" and "32 per core" are the same +number. Sweeping the worker count against the cores the server actually runs on, +at 64 connections: + +| server cores | 8 | 16 | 32 | 64 | 128 | +| --- | --- | --- | --- | --- | --- | +| 1 | 77,084 | 106,611 | 115,893 | **138,076** | 133,755 | +| 2 | 126,939 | 177,399 | 214,091 | 248,507 | **252,100** | + +Doubling the cores nearly doubles throughput at a fixed worker count, but barely +moves where the curve peaks: one core peaks at 64, two cores are flat from 64 to +128. **The optimum tracks the offered concurrency, not the core count** -- this +sweep ran at 64 connections and both rows peak at workers close to it, which is +also why 64 workers beat 256 at 256 connections while 256 workers collapsed. + +The working rule is `workers ~= min(concurrent connections, 64..128)`, where the +upper bound is the stack-scan ceiling below, not a property of the machine. A +default derived from `Runtime.availableProcessors()` would be the wrong shape -- +and that method is not in `vm/JavaAPI` anyway. + +Measured on 1 and 2 cores only: this VM has 4 and the load generator needs two of +them, so whether the ceiling moves on a 16-core host is **untested**. + +## What the syscall census found + +The first version of this comparison blamed the collector. That was half wrong: +the collector is expensive, but the request path was worse, and counting +syscalls is what settled it. Both servers traced under identical load: + +| per request | Go | CN1 before | CN1 after | +| --- | --- | --- | --- | +| `epoll_ctl` | 0.00 | **2.00** | 0.00 | +| `fcntl` | 0.00 | **4.00** | 0.00 | +| `futex` | 0.05 | **3.77** | 0.03 | +| `write` / `sendto` | 1.00 | **2.00** | 1.00 | +| `read` / `recvfrom` | 1.02 | 1.00 | 1.00 | + +The reactor handed each connection back to the poller after **every response**, +so a keep-alive connection paid an `epoll_ctl` pair, two blocking-mode flips and +a cross-thread handoff per request. The `futex` traffic from that handoff alone +was 80% of our syscall time. Go's netpoller registers a connection once, +edge-triggered, and the goroutine keeps reading. + +Three changes, following what Go does: + +1. **The worker holds the connection.** After responding it waits briefly for the + next request instead of returning the descriptor to the reactor. The timeout + alone does **not** bound that hold -- a client that keeps sending is readable + every time -- which is the bug described above. What bounds it is handing the + connection back as soon as another connection is waiting and no idle worker can + take it. +2. **That wait is one `poll`.** The first attempt set and restored `SO_RCVTIMEO` + around each wait; the trace showed it cost **4 `setsockopt` per request**, 15% + of syscall time. `poll` is one syscall and changes no socket state, so the + deadline governing a real request read is never disturbed. +3. **One write per response.** Head and body go out together when the body is + small and in memory. + +Effect: p50 fell from 1.16 ms to 48 us at 64 connections - past Go - and +throughput rose about 25%. Which is where the collector takes over. + +## What is left: the tail, and where it comes from + +`[GCSTALL]` charges every mutator stop to a cause. On `/json` at 64 workers: + +``` +[GCSTALL-T] threads=66 stallMs=22624 dutyPct=66.2 +cause=pacingVolume count=4219 totalMs=456202 meanUs=108130 p99Us=131072 +cause=signalStop count=4760 totalMs=1597 meanUs=335 p99Us=4096 +cause=nativeResume count=5780945 totalMs=371 meanUs=0 +markMs=387.4 stackMs=360.7 liveSlotKb=176687 allocated 462 bytes/request +``` + +The tail is **not** a mark pause: `signalStop` is 335 us mean, 4 ms p99. It is +`pacingVolume` -- the run-ahead cap parking mutators for a mean of **108 ms** when +the collector falls behind. That park is the p99, and the workers run only 66% of +wall time. + +### Proved causally, by moving one variable at a time + +`[GCSTALL]` names a cause; it does not prove one. Two knobs were added to settle +it by experiment -- `CN1_GC_PACING_CAP_MB` (overrides `cn1BibopPacingCap`) and the +existing `WORKERS` -- and each was moved with everything else held fixed. Same +binary, 2 pinned cores, 64 connections, `/plaintext`, medians of repeated runs. + +**Cause 1 -- the run-ahead cap parks mutators for a whole collection.** Raising it +moves the tail by an order of magnitude AND buys throughput, on both routes: + +| route | cap | req/s | p99 | +| --- | --- | --- | --- | +| /plaintext | default | 160274, 157707 | 44.4 ms, 45.4 ms | +| /plaintext | 2048 MB | 177966, 172337 | **5.3 ms, 4.3 ms** | +| /json | default | 115748, 118407 | 69.7 ms, 82.0 ms | +| /json | 2048 MB | 139050, 128940 | **8.4 ms, 9.0 ms** | + +It is a cliff, exactly as the comment on `CN1_BIBOP_GC_MAX_CAP_MULTIPLIER` says: +`cn1PacingPark` spins on `usleep(50)` until `cn1PacingVolume` drops, and that +counter only drops when a cycle ENDS. So crossing the cap costs a full collection, +whoever crosses it. That is a p99 shape -- the median is untouched. + +**The cap is load-bearing; it cannot simply be removed.** With it set past reach +the `/json` server died during the run. Whatever replaces it has to keep bounding +run-ahead. Note also which branch this is: `cn1ProcessHeadroom()` returns -1 only +where there is no per-process limit, and iOS always takes the other branch through +`os_proc_available_memory()`, so this path is the server path and tuning it does +not touch jetsam behaviour. + +**Cause 2 -- worker threads oversubscribing the cores.** With the cap left alone, +only `WORKERS` moving: + +| workers | req/s | p50 | p99 | +| --- | --- | --- | --- | +| 2 | 110551 | 547 us | **2.27 ms** | +| 4 | 111974 | 530 us | 16.2 ms | +| 8 | 126384 | 422 us | 49.1 ms | +| 16 | 162623 | 396 us | 44.6 ms | +| 64 | 245538 | 225 us | 61.3 ms | +| **Go, GOMAXPROCS=2** | **240864** | **245 us** | **1.56 ms** | + +Two things fall out of that table. The first is that **throughput is already at +parity and the median is better than Go's** -- 245538 against 240864, 225 us +against 245 us. The whole remaining gap is the tail. The second is that the tail +is bought with threads: 64 runnable OS threads on 2 cores wait on the OS +scheduler, while Go multiplexes goroutines onto 2 OS threads in user space and +never queues behind a timeslice. + +Both causes are independent and compose: + +| configuration | req/s | p99 | +| --- | --- | --- | +| 64 workers, default cap | 219361 | 64.98 ms | +| 64 workers, 2048 MB cap | **241134** | **14.67 ms** | +| 16 workers, 2048 MB cap | 170704 | 6.29 ms | +| 8 workers, 2048 MB cap | 138822 | 4.16 ms | +| 2 workers, 2048 MB cap | 118747 | 2.28 ms | + +At 64 workers with the cap corrected the server is at **100.1% of Go's throughput +with a better median and a tail 4.4x smaller than before** -- and still 9x Go's, +which is the thread-oversubscription residual. + +### The zero-copy read: what the bisection found + +`CN1_HTTP_ZERO_COPY` helps one route and hurts the other, which no single-cause +story explains. Mode 2 was added to split mode 1's two differences from mode 0: +it uses mode 1's NATIVE (read into the thread's foreign buffer) and mode 0's JAVA +(copy into a fresh heap array). Medians of 3 reps, 64 workers, 2 pinned cores: + +| route | mode 0 recv+heap | mode 1 foreign | mode 2 foreign+heap | +| --- | --- | --- | --- | +| /plaintext | 249524 | 234939 | 250962 | +| /json | 158972 | 166289 | 150654 | + +**Mode 2 lands on mode 0 on both routes, so the native read costs nothing** and is +not what moved either number. Mode 1 against mode 2 therefore isolates a single +thing -- keeping the foreign off-heap array in a Java field rather than copying +out of it -- and that one thing is worth **-6.4% on /plaintext and +10% on /json**. + +Both signs come from the same trade. Mode 1 skips a per-request allocation and in +exchange `Conn.buffer` points outside the heap, so the fast range check in the +mark path fails and the object has to be resolved as an immortal root on every +traversal. On `/json`, which is allocation bound, the saved allocation is worth +more than the collector's extra work. On `/plaintext` there is little GC pressure, +so the saving buys little and the marking cost is paid anyway. The default is a +judgement about the workload, not a fact about the code. + +### What Go actually does differently (read from go1.23.12 source) + +The comparison is against `net/http` on go1.23.12. Reading its scheduler and +poller alongside ours explains every gap that is left, and the syscall census +below confirms the reading rather than resting on it. + +**1. Go has no poller thread, and no handoff.** `netpoll()` is called from +`findRunnable()` -- the scheduler's own loop, on whatever M has run out of work +(`runtime/proc.go`). What it does with the result is the whole story: + +```go +if list, delta := netpoll(0); !list.empty() { + gp := list.pop() // take the first ready goroutine + injectglist(&list) // the REST go to run queues + return gp, false, false // and RUN IT ON THIS THREAD +} +``` + +The thread that polled runs the work itself. Our reactor cannot: `handOff` does +`reactor.remove(fd)`, allocates a `Runnable`, enqueues it, and wakes a worker, +which is a cross-thread dispatch per request. Ours is also ONE thread doing the +polling; Go's polling capacity scales with GOMAXPROCS because any M can do it. + +**2. Go registers each fd once, edge-triggered.** `netpollopen` sets +`EPOLLIN|EPOLLOUT|EPOLLRDHUP|EPOLLET` and there are exactly three `EpollCtl` call +sites in `netpoll_epoll.go` -- the wake eventfd, one ADD per fd, one DEL per fd. +**Zero per request.** Ours is level triggered, so `handOff` MUST deregister +before a worker reads (an fd left registered is reported ready again and two +workers land on one connection) and re-register afterwards: two `epoll_ctl` per +handed-back request. + +**3. Go reads optimistically.** `internal/poll.FD.Read` calls `syscall.Read` +first and only parks on `EAGAIN`. A ready connection costs one syscall and never +touches the poller. + +**4. Go's GC charges the allocator WORK, not SLEEP.** `assistWorkPerByte` is +documented as "the ratio of scan work to allocated bytes that should be performed +by mutator assists". An over-budget goroutine computes a debt proportional to its +own excess, first tries to steal `bgScanCredit` (free when the background workers +are ahead), and otherwise does the marking itself. Parking is a last resort and +is woken by CREDIT, not by the end of a cycle. + +Ours does the opposite, and this is the sharpest single contrast in the whole +comparison: `cn1PacingPark` spins `usleep(50)` until `cn1PacingVolume` drops, and +that only happens when a cycle ENDS. Go's assist is bounded, proportional, and +*productive* -- the work it does advances the very cycle it is waiting on. Ours +is unbounded in the sense that matters (a whole collection), disproportionate +(whoever crosses the cap pays for everyone) and pure loss (sleeping makes the +cycle no shorter). + +### The syscall census confirms it + +`strace -f -c`, both servers, same load, 2 pinned cores, 64 connections, +normalised per request (absolute rates are meaningless under strace; the ratios +within a run are not): + +| syscall | Go | CN1 | | +| --- | --- | --- | --- | +| read / recvfrom | 1.436 | 1.503 | the same I/O | +| write / sendto | 1.397 | 1.502 | the same I/O | +| futex | 0.063 | 0.437 | **6.9x** -- the cross-thread dispatch | +| epoll_ctl | 0.0021 | 0.087 | **41x** -- level-triggered re-registration | + +**The actual I/O work per request is identical.** What differs is entirely +coordination: waking another thread, and re-arming the poller. Note CN1's +`epoll_ctl` is only 0.087 rather than 2.0 because the keep-alive linger keeps +about 91% of requests inside the worker they are already on -- the linger exists +precisely to dodge the path this table is measuring. + +### Why each measured gap follows + +- **The 119-129k plateau below 64 workers** is the dispatch. Every request that + is not held by the linger pays deregister + allocate + enqueue + futex wake + + context switch + re-register. Go pays none of it. +- **Why we need 64 workers at all**: our unit of concurrency is an OS thread, so + "keep this connection attached and skip the dispatch" costs a whole thread. Go + keeps 64 connections attached with 64 goroutines on 2 OS threads. +- **Why the tail is 40x worse** follows from that: reaching Go's throughput + requires workers >= connections, which puts 64 runnable threads on 2 cores, and + the OS scheduler supplies the tail. The GC park adds the rest, independently. +- **Why p50 and throughput are already at or above parity**: the per-request work + is the same, and our parsing and response building are cheap (176 bytes/req). + With the dispatch bypassed we beat Go. Neither the runtime nor the handler code + is the problem -- the concurrency architecture is. + +**The fix does not require green threads.** Point 1 is the expensive one, and the +trick that removes it is available to us: let the WORKERS poll. A worker with +nothing to do calls `epoll_wait` itself and runs the first ready fd inline, +instead of a dedicated reactor thread waking it. That deletes the futex wake and +the queue, and combined with edge-triggered registration deletes the two +`epoll_ctl` as well -- without any goroutine machinery, and without a thread per +connection. The GC half is a separate change: replace park-until-cycle-end with +proportional mark assist. + +### Tested: does removing the dispatch actually win? + +The reading above says the dispatch is what Go does not pay, so it was +implemented and measured rather than argued about. `CN1_HTTP_POLL_MODE` selects +who takes a ready descriptor from the poller: + +- **0** the reactor thread dispatches (deregister, allocate a task, queue it, + wake a worker, re-register). +- **1** every worker calls the poller itself, descriptors armed `EPOLLONESHOT` + so the kernel hands each to exactly one waiter. +- **2** ONE worker polls at a time, serves the first descriptor on its own + thread and queues the surplus, handing the polling role on with a token. This + is the shape of Go's `findRunnable`. + +**Measuring this needs a null control.** Two runs of the SAME configuration on +this box differed by 19% while the effect under test was around 20%, so an +uncontrolled A/B here is worthless. Every window is therefore three runs -- mode +0, mode 2, mode 0 again -- giving `effect = B/mean(A,C)` and `null = C/A` from +the same minutes. Windows whose null exceeds 5% are discarded rather than +averaged in. + +15 windows, 9 of them usable once the noisy ones are dropped: + +| workers | usable | discarded | effect (poll / dispatch) | the windows | +| --- | --- | --- | --- | --- | +| 4 | 2 | 3 | **+32.2%** | 1.191, 1.453 | +| 8 | 3 | 2 | -2.0% | 0.972, 0.980, 1.007 | +| 16 | 4 | 1 | **-32.5%** | 0.660, 0.669, 0.682, 0.726 | + +Read the two ends together, because that is the finding: **the handoff costs +about a third when workers are few, and removing it costs about a third when +workers are many**, with the crossover near eight workers on two cores. You need +a large pool to hide the dispatch, and a large pool is what produces the 61ms +tail measured further up. No point on that curve has both. That is the tension a +thread-pool server cannot resolve by tuning, and the reason the interesting +direction is decoupling "many contexts" from "many threads" rather than moving +the dispatch around. + +**The dispatch is a real cost, and removing it is not a win.** Both halves are +supported. On an idle machine the low-worker gain reproduced across two +independent implementations -- +40% and +31% at two workers, +24% and +18% at +four -- and the paired window above puts it at +19% against a 0.9% floor. But at +eight and sixteen workers removing the dispatch LOSES, and the sixteen-worker +result is the most reproducible number in the set. + +The reason is visible in the design rather than the numbers: **while the single +poller is serving a request, nobody is in `epoll_wait`** until another worker +picks up the token, whereas a dedicated reactor thread never stops polling. Our +architecture buys continuous polling at the price of a handoff per request, and +that trade wins as soon as there are enough workers to hide the handoff. Go pays +neither because it has many threads that can poll and switches contexts in user +space; that is the goroutine model, and it is blocked here by the CONSERVATIVE +collector -- stacks cannot be moved, so they cannot start small and grow, so a +context per connection is not cheap. It is not blocked by C. + +Two implementation defects were found and fixed on the way, both worth recording +because each looked like an architectural result until it was understood: + +- **Mode 1 wakes every worker per event.** All of them block in `epoll_wait` on + one set, so one arrival wakes all; ONESHOT still gives the descriptor to + exactly one, but the other wakeups happen. The damage scales with the pool: + +40% at two workers, -26% at eight, -44% at sixteen. +- **Mode 1 of mode 2 busy-waited.** The worker that lost the race for the poller + polled the queue on a 2ms timeout, so on two cores seven of eight workers spun + against the cores the server needed (95435 against 113345 at eight workers). + Handing the polling role over with a token so waiters PARK is what Go does with + `stopm`/`wakep`. + +**Where the evidence points next is not this.** Per request the census puts us at +6.9x Go's futex rate, and the reactor loop calls `handOff` once per ready +descriptor -- so twenty ready descriptors are twenty task objects and up to +twenty wakes. One wake can carry all twenty. That divides the dominant cost by +the batch size, gets LARGER under exactly the load where this server is weakest, +keeps the dedicated reactor the table above vindicates, and needs neither +coroutines nor C. + +### What a context switch costs, by mechanism + +The reason to want virtual threads here is that a suspended context should be far +cheaper than the thread handoff it replaces. That is one number, so it was +measured before any of it was designed. Ping-pong between two contexts, arm64, +two pinned cores: + +| mechanism | ns per switch | +| --- | --- | +| `_setjmp`/`_longjmp` (musl) | **4** | +| `_setjmp`/`_longjmp` (glibc) | **8** | +| `swapcontext` (glibc) | 403 | +| mutex + condvar handoff between two threads | **21181** | + +**The switch is three to five thousand times cheaper than the handoff.** That is +the whole case for the design, and it is why no amount of tuning inside a thread +pool reaches it: the pool pays 21us to move work between threads, and a context +switch costs single-digit nanoseconds. + +Two portability findings that constrain the implementation: + +- **musl has no `makecontext`/`swapcontext`.** They are obsolescent in POSIX 2008 + and musl omits them, so the portable route for CREATING a stack is not + available on the static target. A stack can still be established with no + assembly by raising a signal with `SA_ONSTACK` and `_setjmp`ing inside the + handler, which is what libcoro's SJLJ backend does; measured working above. +- **glibc aborts a cross-stack `_longjmp` under `_FORTIFY_SOURCE`.** + `__longjmp_chk` reports "longjmp causes uninitialized stack frame" at + `-D_FORTIFY_SOURCE=1` and `=2`, and passes with hardening off. Distributions + enable hardening by default, so a setjmp-based switch is green wherever it is + tested here and dies in somebody else's build. This is the argument for a small + per-architecture stub -- set the stack pointer and jump, about twenty + instructions for arm64 and x86_64 -- rather than for a portable C trick. + +### Virtual threads: a context per connection without a thread per connection + +`CN1_HTTP_POLL_MODE=3` gives every connection a virtual thread. Host threads poll +and resume; a connection's virtual thread runs until it finishes or asks for +bytes that have not arrived, at which point it parks INSIDE the ordinary blocking +read and the host thread goes and runs another one. `serve()` is untouched -- +still written in the blocking style, and unaware it is not on a thread, which is +the property that makes this worth having rather than a rewrite into callbacks. + +**Why this and not more tuning of the pool.** The paired experiment over modes 0 +to 2 showed the handoff is worth about a third of throughput at four workers and +that REMOVING it costs about a third at sixteen. Both are true because a pool +large enough to hide the handoff is a pool large enough to lose to the OS +scheduler. The assumption that makes those irreconcilable is "a context per +connection means an OS thread per connection", and a virtual thread is how that +assumption stops holding. + +**What it rests on, measured.** Handing work between OS threads costs 21181ns on +this hardware; switching a virtual thread costs 2.6ns. A parked OS thread costs +~118KB resident (the figure is in nativeMethods.m, where the eager memset was +removed for exactly this reason); a parked virtual thread costs its C stack plus +a lazily faulted Java stack, and its C stack is small because ParparVM keeps Java +locals and the operand stack in `threadObjectStack` rather than on the machine +stack -- so the C frames hold only pointers and temporaries. + +**Correctness first.** 50/50 requests over one kept-alive connection, 40/40 over +separate connections, correct JSON, no non-2xx and no socket errors under 20s of +concurrent load, and the process healthy afterwards. + +**Throughput, paired against mode 0 with a null control.** The host was busy +during this run and many windows were discarded at 20-40% noise; what survives: + +| route | host threads | null | effect | +| --- | --- | --- | --- | +| /plaintext | 2 | 1.7% | **+33.6%** | +| /plaintext | 4 | 1.8% | **+28.4%** | +| /plaintext | 8 | 5.7% (marginal) | +46.4% | +| /plaintext | 16 | 3.7% | **-23.3%** | + +**The crossover is the same one as before and it is not a virtual-thread +problem.** Sixteen host threads oversubscribe two cores whatever they are +running, so mode 3 has to be configured the way its premise implies: a host +thread PER CORE, with the virtual threads supplying the concurrency. Comparing +mode 3 at sixteen hosts against mode 0 at sixteen workers measures the host +threads, not the design. + +**A cost worth stating**: one virtual thread per connection is one VM thread +state per connection, and the process measured ~10% higher RSS than the pooled +path at 64 connections. The Java stacks are mapped lazily so this scales with +what connections actually touch rather than with their number, but it is not +free. + +### Host threads must track CORES, not expected concurrency + +In virtual-thread mode `workerCount` stops meaning "how many requests may be in +flight" -- the virtual threads supply that, one per connection -- and a host +thread only earns its keep while there is a core free to run it on. Past that +they contend for the cores the server needs. + +Pinned to two cores, `wrk -c64`: + +| hosts | requests | +| --- | --- | +| 2 | 257297 | +| 16 | **117** | + +Unpinned, with cores to spare, the effect vanishes entirely -- 2, 4, 8, 16 and 32 +hosts all serve between 760000 and 834000 in the same test and every one stays +healthy. So this is not a bug in the scheduler, it is host threads competing for +CPU, and the ceiling has to be read from the machine at runtime rather than +guessed. `start()` now clamps the host count to `availableProcessors()`. + +**What this does NOT show.** An earlier revision of this section claimed the same +sweep proved a THROUGHPUT optimum at hosts == cores. It does not. Across three +reps the spread within one host count (70%, 84%, 100% of Go at two hosts; 78%, +81%, 109% at eight) is wider than any difference between host counts, on a +machine that was running a browser and a Spotlight index. The robustness finding +above survives that noise because 117 against 257297 is not a 30% effect; the +performance one does not. + +**Honest throughput position.** Across all eight usable windows virtual threads +measured 70, 78, 81, 84, 100, 106, 108 and 109 percent of Go -- median 92%, with +three windows above parity. That is indistinguishable from Go within this host's +noise and is NOT a demonstration of parity. Settling it needs an idle machine, +not more code. + +### Virtual threads against Go: the tail is closed, the syscalls are not + +Once the collector was no longer being blocked (see below), the comparison became +meaningful. p99 over five windows, and this half of the comparison is trustworthy +even on a busy host because tail latency resists background load in a way +throughput does not: + +| | p99 median | range | +| --- | --- | --- | +| pool, 64 workers | 59.70 ms | 54.76 - 67.50 | +| **virtual threads, 4 hosts** | **1.58 ms** | 1.51 - 1.78 | +| Go, GOMAXPROCS=2 | 1.58 ms | 1.35 - 1.76 | + +**Identical to Go, and 37.8x better than the pool, on four host threads rather +than sixty four.** That is the whole architectural claim demonstrated: a context +per connection without a thread per connection. The tail was the entire remaining +gap against Go in every earlier measurement here. + +Throughput is 78% of Go (236357 against 303573) and that number is NOT solid -- +one of five windows had a clean null, the rest 8-21%, on a host running Spotlight +and a browser. + +**Where the throughput goes, per request, from a syscall census:** + +| syscall | virtual threads | Go | +| --- | --- | --- | +| recvfrom | 1.91 | 1.03 | +| sendto / write | 1.91 | 1.00 | +| ppoll | **1.90** | **0** | +| epoll_ctl | 0.021 | 0.003 | +| futex | **0.012** | 0.047 | + +The futex is essentially gone -- 0.012 against Go's 0.047 -- so the virtual +threads are doing exactly what they were built to do. What is left is that a +request costs about 5.7 syscalls here and about 2 in Go, and the largest single +line is a `ppoll` Go never makes: `awaitReadable` asked whether a descriptor was +readable immediately before a read that parks on EAGAIN anyway and would have +learned the same thing. Go's `internal/poll.FD.Read` calls `syscall.Read` +straight away for exactly this reason. + +Two more remain and are not yet done: the response takes about two `sendto` where +Go takes one, and the keep-alive loop takes a speculative second `recvfrom`. + +### Why virtual-thread mode stopped serving after one burst + +Three separate bugs, each found with a debugger or a counter rather than by +reasoning, and each of which alone was enough to stop the server. + +**1. The collector waits for ever on a finished virtual thread.** This was the +one that mattered. Stop-the-world does this for every lightweight thread: + +```c +if(t->lightweightThread) { + t->threadBlockedByGC = JAVA_TRUE; + while(t->threadActive) { usleep(500); } // no timeout +} +``` + +A virtual thread's ThreadLocalData is registered in `allThreads` and flagged +lightweight, so when one FINISHED and its state was left in the list, nothing +would ever clear `threadActive` again and the collector blocked on it. Proof was +the cycle counter under `CN1_GC_LOG_CYCLES=1`: burst one reached cycle 3, and +burst two was still at cycle 3. No cycle ever completed again, so the allocation +pacing never released and the server sat at a few hundred requests a second +looking completely idle -- 8% of a CPU, no crash, no spin. + +A platform thread calls `markDeadThread` at the end of `threadRunner` for exactly +this reason. A virtual thread owes the collector the same announcement, made from +the HOST after the switch back: calling it from inside the body frees +`threadObjectStack`, which is the Java stack the body is still standing on, and +kills the process inside the first burst. + +**2. GC backpressure pins host threads.** `cn1PacingPark` sleeps until a cycle +ends, and a host thread has no virtual thread to hand back, so it just stops +polling. gdb found all four hosts in that loop at once, three inside +`HttpServer.serve`. The pacing park now yields the virtual thread instead, and +connections are pinned to a host so the VM's per-OS-thread state -- the BiBOP +page cache, the pacing claim, the mark buffer, `cn1TlsSelf` -- stays valid across +a park. + +**3. The scheduler allocated on the host's hot path.** The run queue was a +LinkedList of boxed Longs, so every yield allocated twice ON THE HOST, and those +allocations hit the same backpressure. gdb caught the accepting host inside +`LinkedList.addLast` inside the scheduler. It is now a preallocated ring of raw +handles: a scheduler that allocates becomes a customer of the backpressure it +exists to relieve. + +**What the fix is worth.** Four bursts, one server, no degradation: + +| burst | requests | still serving | +| --- | --- | --- | +| 1 /plaintext | 1047890 | yes | +| 2 /plaintext | 1043497 | yes | +| 3 /plaintext c=64 | 1030535 | yes | +| 4 /json c=64 | 778673 | yes | + +Zero socket errors throughout. Note the magnitude as well as the stability: the +first burst went from about 205000 requests to 1047890. Every earlier +virtual-thread measurement in this file's history was taken against an already +crippled collector and is void. + +**Two traps worth remembering.** `-Wl,--strip-all` is on by default, so a +backtrace from a deployed binary is a list of hex addresses; `CN1_LINK_DEBUG=1` +keeps the symbols. And a counter that is only printed from an idle poll is +invisible exactly when the server is stuck -- "accepts=0 while serving 204000 +requests" looked like a contradiction for hours and was a report from start-up. + +### What pins a host thread, found with a debugger + +Virtual-thread mode served one burst of traffic and then stopped accepting for +good. Four hypotheses were spent on it by inference -- the EPOLLONESHOT re-arm, +a synchronized map, virtual-thread creation failing, a missing safepoint bracket +-- and every one was wrong. Attaching gdb answered it in a single backtrace: + +``` +cn1PacingPark (usleep 50) <- the collector's allocation backpressure + cn1BibopMaybeGc + cn1BibopAlloc + codenameOneGcMalloc + HttpServer_asciiString + HttpServer_readRequest + HttpServer_serveOne + HttpServer_serve <- running ON a virtual thread +``` + +All four host threads were in that loop at once, three of them inside +`HttpServer.serve` on different descriptors. `cn1PacingPark` spins on +`usleep(50)` until uncollected volume falls, which only happens when a cycle +ENDS, and ending one needs the mutator progress the spin is preventing. Nothing +was polling, so nothing was accepted, and it never recovered. + +**The general rule this is an instance of**: any blocking operation that is not +virtual-thread aware pins its HOST, and a host thread is not a spare resource -- +it is one of the few threads that poll. The known instance of that rule is a +monitor held across a park; the one that actually bit is the collector's own +backpressure, which fires wherever Java allocates, which on a server is +everywhere. + +Two notes for whoever reads the counters next. `-Wl,--strip-all` is on by +default, so a backtrace from a deployed binary is a list of hex addresses; +`CN1_LINK_DEBUG=1` keeps the symbols. And a counter printed only from an idle +poll is invisible exactly when the server is stuck -- the "accepts=0 while +serving 204000 requests" that looked like a contradiction for hours was a report +from start-up, because once the hosts pin, no host is ever idle again to print +another one. + +### Two explanations that measurement killed + +Worth recording, because both were plausible and both were wrong: + +- **"Workers block in the keep-alive linger, which is why the pool must be large."** + Setting `CN1_HTTP_KEEPALIVE_LINGER_MS=0` leaves low-worker throughput exactly + where it was (111897 vs 110551 at 2 workers; 112379 vs 111974 at 4). The linger + is not what caps a small pool. It is, however, what makes a LARGE pool fast: + at 64 workers, removing it drops throughput from 245538 to 87475. +- **"Then the parks are what a small pool cannot absorb."** Also wrong. Raising + the cap at 4 workers fixes the tail (32.4 ms -> 2.43 ms) but leaves throughput + at 125500. + +### Why the pool has to be larger than the core count: the reactor is the ceiling + +The discriminator is connections against a FIXED pool. With connections <= workers +nothing is ever queued, the fairness rule never fires, every connection stays with +its worker for the whole run and the reactor is out of the path. With connections +>> workers every request pays a dispatch through it. + +| workers | connections | req/s | p50 | p99 | +| --- | --- | --- | --- | --- | +| 8 | 8 | **225645** | 28 us | **2.44 ms** | +| 8 | 64 | 128804 | 408 us | 48.2 ms | +| 2 | 64 | 118913 | 480 us | 2.56 ms | +| 4 | 64 | 119433 | 464 us | 29.8 ms | +| 64 | 64 | 245538 | 225 us | 61.3 ms | + +Every row reproduced on a second rep within a few percent -- 8/8 gave 222569 at +2.46 ms, 2/64 gave 121354 at 2.52 ms, 4/64 gave 119823 at 30.7 ms, 8/64 gave +126875 at 51.3 ms -- so the plateau and the two low-tail cells are not samples. + +Throughput sits at 119-129k for EVERY pool smaller than the connection count and +then doubles the moment workers >= connections. That plateau is the single reactor +thread's dispatch rate: a workload with more connections than workers is capped +there however large the pool. The keep-alive linger exists to bypass it, and a +worker can only hold one connection, which is why bypassing it for N connections +takes N workers. The 64-worker default is not a tuning constant -- it is what +makes connections <= workers for a 64-connection benchmark. + +The best cell in the whole matrix is **8 workers and 8 connections: 225645 req/s +at p99 2.44 ms** -- 94% of Go's throughput and within 1.6x of its tail, on 8 +threads rather than 64. Whatever replaces the handback path should aim there. + +Note also what the two low-tail rows have in common. `w=2,c=64` has connections +far above workers and still holds p99 to 2.56 ms, so the handback alone does not +produce the tail; `w=8,c=8` has 4 threads per core and holds 2.44 ms, so thread +count alone does not either. The bad cells need BOTH -- threads competing for +cores AND workers competing for connections. Neither factor is sufficient, which +is why single-variable sweeps of each looked contradictory. + +Why the collector falls behind is **not yet established**, and the analysis that +previously stood here was wrong three times over. What went wrong is worth more +than what it claimed: + +**The measurement bug.** `consWords` is a **cumulative running total** since +process start -- the source says so at `cn1GcProbeResetPhases`: "the cumulative +counters (matured, consWords, staleSkips, ...) are deliberately left alone: they +are running totals and the reader diffs them". `markMs` and `stackMs` beside it +are **per-cycle**. Every cross-configuration comparison of `consWords` here read a +running total as if it were one cycle's work, and two different time bases were +divided into each other. + +Corrected, the scan is unremarkable: 4,309,657 words over 46 cycles is **~94K +words per cycle -- about 750 KB across 66 threads, ~11 KB of live stack per +thread**, which is exactly what an HTTP worker should have. The "26 MB floor" and +"34 MB per cycle" figures previously reported here were that bug, not a finding. + +**The attribution bug.** `stackMs` brackets `cn1GcScanThreadNativeStack`, and the +loop inside it does not only walk words -- it calls `gcMarkObject` on every +resolved reference, which resolves the pointer and pushes to the mark worklist. So +`stackMs` is *"walk one thread's stack and enqueue what it finds"*, not *"time +spent scanning stack words"*. **"93% of mark time is the conservative stack scan" +does not follow from it**, and neither does the conclusion that scanning less +stack is the lever. + +That also explains the two null results below without any new theory: a range +filter and a presence bitmap only make *rejection* cheaper, and rejection was +never shown to be where the time goes. + +**What is still solid:** every throughput, latency and allocation number in this +file (those were measured directly, not modelled); that the tail is +`pacingVolume` back-pressure rather than a mark pause; and that cutting allocation +27-fold moved throughput and tail together. **What is open:** what actually +dominates a ~300 ms mark cycle. Isolating it needs a counter that separates +walking, resolving, enqueueing and draining -- which the probe does not currently +have. + +Only 1.3% of the words scanned resolve to an object. + +`/json` allocates 462 bytes per request against `/plaintext`'s 176. The +difference is the handler's per-request `LinkedHashMap`, which is the honest +counterpart to Go marshalling a struct -- a direct-to-sink JSON API would beat +Go's number by doing less work than Go does, so it is deliberately not measured +here. + +**The lever that is established is allocation per request** -- it is what moved +throughput and the tail together, 27-fold. Whether anything inside the collector +is worth attacking is **not established**, because the phase attribution that +suggested it turned out not to say what it looked like it said. + +### Two optimizations that did NOT work, and why + +Recorded so nobody spends the day twice. Both targeted the conservative scan's +per-word cost (~290 ns, which is ~300x slower than streaming the same memory): + +1. **A lo/hi range filter** rejecting words outside the heap's address span + before any lookup. **No measurable change** - the thread stacks are mmap'd + inside the same span as the heap. +2. **A 64KB-granule presence bitmap** over that span, small enough to stay in + cache. **Also no measurable change** - the words genuinely land in heap + granules and are rejected by the finer slot checks (`bumpIndex`, `FREE_MARK`, + `__heapPosition`), not by the coarse ones. + +3. **A 16x smaller thread stack** (`-DCN1_THREAD_STACK_BYTES=1024*1024`, and the + macro really does reach `pthread_attr_setstacksize` -- that was checked, because + a flag that silently does nothing looks exactly like a null result). + **No change**: 543 ms of stack scan against 521 ms. The scan covers the used + depth, not the reserved region, so the reservation is not the lever. + +Those null results say the cost is neither the reject path nor the stack +reservation. They do NOT establish where it is -- an earlier revision read them as +pointing at "scan less stack", which the attribution bug above shows was never +supported. Allocating less, so cycles run less often, is the one lever with +evidence behind it. + +## The clamp, and the two bugs found verifying it + +Virtual-thread mode clamps the requested `WORKERS` to the core count, because host +threads track cores rather than expected concurrency (the concurrency comes from +the virtual threads). Verifying that clamp on two pinned cores is what turned up +everything below, which is the argument for verifying a fix rather than reasoning +that it must work. + +**The clamp itself holds.** Where the unclamped build served 117 requests at 16 +hosts on two cores, every host count now lands in the same band: + +| WORKERS | rep1 | rep2 | Go (`GOMAXPROCS=2`) | +| --- | --- | --- | --- | +| 2 | 252,101 | 263,999 | 303,307 / 318,702 | +| 16 | 254,164 | 267,232 | " | +| 64 | **0** | 255,641 | " | + +### 1. A never-used thread pool, and a segfault + +That `0` is not a slow run. The server bound, served nothing, and was **gone** by +the end of the window (1.5M client write errors, `wait` status 139 -- SIGSEGV). +It reproduced at 2 runs in 10. + +`WORKERS` still sized `Executors.newFixedThreadPool`, and in this mode that pool +is dead weight: `workers.execute()` is reached only from `handOff()`, which is +reached only from `pump()`, which runs only on the dispatching path. All 64 OS +threads were created (69 in `/proc//task` against 5 expected) and never given +anything to do -- while the collector still scanned each one's stack every cycle +and still waited for each at every safepoint. + +Holding the host count equal via the clamp made the pool size the only variable: + +| arm | workers | bursts | died | +| --- | --- | --- | --- | +| A | 64 | 2 | **2/6** | +| B | 4 | 2 | 0/6 | +| D | 4 | 1 | 0/6 | + +The pool is no longer created in this mode. Arm A then ran **12/12 clean**, at +unchanged throughput -- this buys robustness, not speed. + +Re-running the clamp against the fixed build, every cell is populated and the +spread across host counts is noise: + +| WORKERS | rep1 | rep2 | our p99 | Go | Go p99 | +| --- | --- | --- | --- | --- | --- | +| 2 | 265,954 | 245,568 | 1.72 / 1.75 ms | 328,943 / 316,304 | 1.52 / **56.42** ms | +| 16 | 264,708 | 251,083 | 1.66 / 1.47 ms | " | " | +| 64 | 266,252 | 256,317 | 1.59 / 1.62 ms | " | " | + +On two pinned cores that is about 81% of Go's throughput. The p99 column is worth +a second look rather than a claim: our tail sat between 1.47 and 1.75 ms in all +six readings, and Go's second replicate spiked to 56 ms. One spike is not a +finding -- it is one reading, on a loaded shared host, and it has not been +repeated -- but it is the reason the tail is measured per replicate here instead +of being averaged away. + +### 2. A use-after-free between the collector and a freed virtual thread + +Reading the collector to explain that crash turned up a separate, genuine race. +The collector does not stop the world and then scan; it stops and scans **one +thread at a time**, rebuilding its virtual-thread snapshot inside that loop, and +every other thread keeps running -- including host threads, whose job is finishing +connections and freeing the virtual threads that served them. A pointer copied +into the snapshot could therefore be freed, and its stack unmapped, before the +scan that snapshot feeds read it. + +`cn1VirtualThreadFree` now unlinks the virtual thread immediately but defers the +release when a scan is in progress; the collector drains the retired list when the +scan ends. The free and the snapshot serialise on the registry lock, so the +handoff is exact rather than merely likely. The lock is never *held* across a scan +-- a frozen thread can hold it -- so the flag is what crosses that boundary. + +Test 8 in `vm/tests/virtualthread/test_virtual_thread.c` covers it, and it was +checked against the unfixed code rather than assumed to bite: with the deferral +neutered it exits **139**, the same signal as production, and it passes with the +deferral in place. + +**What is not established:** whether this race is what killed the WORKERS=64 runs. +Both are SIGSEGV and both widen with thread count, but the reproducer built for it +(`BENCH_IDLE_THREADS=64`, which parks idle Java threads to lengthen the scan loop +without a pool) did **not** crash in 8 runs, so the link is unproven. Two real +bugs were fixed; only the first is tied to the observed failure by measurement. + +### 3. A native name that silently disabled a method + +`VirtualThread.isVirtual()` was inert. Its C body was written +`isVirtualImpl__R_boolean` where the signature rule gives +`isVirtualImpl___R_boolean` -- an empty argument list still contributes its own +leading underscore before `_R`. Nothing linked against the wrong name and nothing +called the method, so the build stayed green. An exhaustive diff of the symbols +the translator declares against the ones we define found exactly this one across +the whole backend native surface. + +`build.sh` now sets `CN1_NATIVE_VERIFY=strict` for **every** backend build rather +than only the no-TLS one. Every native here is ours, so a name that does not match +the generated one is always a bug, never a symbol in a prebuilt library. + +## Where the remaining gap is, and where it is NOT + +Virtual-thread mode against Go net/http, both pinned to two cores, `/plaintext`, +64 connections, interleaved reps. Medians: **Go 318,008, ours 260,156 -- 82%.** + +Three candidates were tested and two were eliminated. The eliminations are the +useful part, because each had a plausible story and a table behind it. + +### It is not the run-ahead cap + +Raising `CN1_GC_PACING_CAP_MB` to 2048 is worth +11-20% on the DISPATCHING path +(table above). In virtual-thread mode it is worth nothing, three reps out of +three -- median 261,411 capped against 267,279 default, slightly WORSE: + +| rep | Go | vt default | vt cap=2048 | +| --- | --- | --- | --- | +| 1 | 279,924 | 267,279 | 253,273 | +| 2 | 321,318 | 266,925 | 261,638 | +| 3 | 321,111 | 268,389 | 261,411 | + +That is not a contradiction, it is the earlier table's own explanation running +out: the cap bound because 64 OS threads oversubscribed two cores and a parked +one held a core it could not use. Virtual threads removed the oversubscription, +so the cap stopped being what anyone waits on. **A tuning verdict measured on one +scheduler does not transfer to another.** + +### It is not collection either -- but "not collection" is not "not memory" + +A diagnostic knob (`CN1_GC_TRIGGER_MB`, the twin of the cap override) raises the +cycle trigger past reach, so no collection runs in the measured window: + +| rep | Go | GC on | GC off | GC cost | +| --- | --- | --- | --- | --- | +| 1 | 314,854 | 245,797 (56 cycles) | 257,157 (1) | +4.6% | +| 2 | 327,403 | 239,837 (56) | 274,483 (1) | +14.4% | +| 3 | 318,604 | 212,071 (55) | 233,089 (2) | +9.9% | + +Collection costs about 10%, and switching it off entirely still leaves us at +**81% of Go**. The tail is the other way round: with collection off our p99 is +406-592 us against Go's 1.37-1.67 ms, three to four times BETTER. + +The obvious reading -- "the gap is not memory" -- is wrong, and worth stating +because it was drawn here first. Turning the collector off does not stop us +ALLOCATING: every object still costs a bump, a write barrier and a fresh cache +line. Go escape-analyses most of a request onto the stack, so it neither +allocates nor collects it, and its heap is small because of that rather than +because its collector is better. What the ablation rules out is the COLLECTOR. +Allocation volume is still live, and is the thing to attack. + +### What the allocation matrix did and did not show + +Both allocation-removing switches were tried in virtual-thread mode: + +| rep | Go | base | +target cache | GC cycles base -> cache | +| --- | --- | --- | --- | --- | +| 1 | 285,584 | 238,937 | 237,471 | 55 -> 43 | +| 2 | 300,789 | 258,879 | 255,254 | 56 -> 48 | +| 3 | 310,776 | 259,549 | 274,720 | 57 -> 51 | + +The target cache is a real **15% cut in allocation** -- the cycle count falls in +all three reps -- and it does not show up in throughput at all. `CN1_HTTP_ZERO_COPY` +is inert here: `ZERO_COPY_READ` ands it with `POLL_MODE != 3`, so setting it under +virtual threads changes nothing. That was not noticed until after a reading of +"95.8% of Go" had been taken from it, which is worth recording as the method +failure it is: the run had FOUR arms that were really two configurations, and the +two identical pairs came back 4.0% and 15.2% apart. **Those pairs are the honest +noise floor of this harness** -- 0.04% to 15% between runs of the same binary -- +and no single-rep conclusion here can resolve less than that. + +### The per-virtual-thread read buffer: attempted, reverted + +Removing the per-request read `byte[]` under virtual threads needs the buffer to +belong to the virtual thread rather than the host, since it parks on one host and +resumes on another. Implemented (pooled, because the array header must be an +immortal GC root and nothing un-roots one), it passed the virtual-thread suite +21/21 and served 175k req/s -- and then produced one truncated response on the +DISPATCHING path, which the same refactor went through. It passed on re-run. + +An intermittent corrupt response is not a flake to re-run until green, and the +prize is one `byte[]` per request, so the refactor was reverted rather than +shipped ahead of an explanation. `ZERO_COPY_READ` is back to refusing to combine +with virtual threads, with the attempt recorded at its definition. + +## A request that was never answered (fixed) + +Chasing the throughput gap turned up a correctness bug that outranked it: the +server occasionally answered a request with **nothing at all**. + +It surfaced twice, from opposite ends, and neither report named it. +`transactionRollsBack` failed with status -1 after exactly 15.05 s -- the test +class's own `setSoTimeout(15000)` expiring -- and `authGuardsMutatingRoutes` +failed with `StringIndexOutOfBounds: -1` out of a bare `substring` on the +response. Replacing that substring with an assertion that PRINTS the body is +what turned it into evidence: the body was empty. About 2 full-suite runs in 6. + +The server log said the rest: + +``` +java.lang.ArrayIndexOutOfBoundsException + at com_codename1_backend_HttpServer.serveOne:1655 +``` + +`Conn.fill` decides whether it may let go of a borrowed zero-copy buffer by +asking whether anything is left unread: + +```java +if(borrowed && available() == 0) { // "start of a new request" + buffer = EMPTY_BODY; pos = 0; borrowed = false; +} else if(borrowed) { + detachPreservingOffsets(); // the guard that should have run +} +``` + +That test is right for a kept-alive connection and wrong for exactly one case. +A POST whose headers arrive in one TCP segment and whose body arrives in the +next reaches the body loop with the header block fully consumed -- so +`available()` is 0 -- while the Request's header slices still name positions in +that very buffer. The first branch dropped the borrow, skipped +`detachPreservingOffsets`, and the next zero-copy read landed on top of the +headers. `wantsKeepAlive` then walked off the end of the array, and because that +call sits OUTSIDE the try block the exception killed the connection with no +response written. + +The discriminator is not "is anything left to read" but "is anything still +pointing at this buffer", so `Conn.parsedFromBuffer` now says so directly: +cleared on entry to `readRequest`, raised once the slices name positions in the +buffer. Verified 8 full-suite runs clean with zero occurrences of the exception +in any server log, against 2 failures in 6 before. + +Two things worth keeping from how it hid for so long. It needs the body to +arrive in a SEPARATE segment, so it never reproduced in isolation -- 400 plain +POSTs and 120 replays of the failing test's exact request sequence were both +clean, and only the full suite's timing produced it. And it never appeared under +virtual threads at all, because `ZERO_COPY_READ` is force-disabled there; every +virtual-thread run in this whole effort was green while the DEFAULT path was the +broken one. + +## Running it + +```bash +CN1_BACKEND_DEMO=demo/bench ../package.sh Bench com.demo musl-arm64 +podman build --platform linux/arm64 -t cn1-bench-go -f Containerfile.go . +podman build --platform linux/arm64 -t cn1-bench-load -f Containerfile.load . +# then, on a Linux host with both binaries staged: +BENCH_DIR=/var/tmp/cn1bench ./run-comparison.sh +``` + +`run-comparison.sh` documents the fairness rules it enforces: same host, the same +two pinned cores for whichever server is running, two other cores for the load +generator, matched handlers, a warm-up before every measured run, and the two +servers never running at once. + +## What the numbers are, and are not + +- Measured on a 4-CPU aarch64 Linux VM (podman machine on an Apple silicon + host), server pinned to cores 0-1, `wrk` to cores 2-3. + +- **Benchmark only on an otherwise IDLE machine, and check that it is.** This is + the single biggest source of wrong numbers here, and it is self-inflicted: + running a `package.sh` build (or a second benchmark) while measuring does not + add a little noise, it destroys the measurement. + + | machine state | one configuration, repeated | spread | + | --- | --- | --- | + | builds running concurrently | 145,719 - 210,660 | **45%** | + | idle | 194,597 - 204,330 (Go), 206,780 - 214,304 (CN1) | **3.6 - 5.0%** | + + Idle, this harness resolves a few percent and is perfectly adequate.

The zero-copy read was working perfectly, every time, and handing the saving straight back one frame later. Clearing the flag once the response is on the wire lets fill() drop the borrow instead. Measured on /plaintext, one binary, the fix behind an env switch so the arms differ in nothing else, six interleaved pairs with the arm order rotating: ahead in 5 of 6, median +4.5%, and p99 better in 5 of 6. The allocation half is not statistical -- detach goes to exactly 0, removing one 97-byte array per request, which the corrected profile put at 37% of everything /plaintext allocates. Found with the allocation profile's new size histogram: 7073173 of 7073834 byte[] allocations were exactly 97 bytes, so one site rather than a dozen. Two earlier candidates had been eliminated by reading the code and both readings were wrong -- fill()'s fallback, which a path counter then showed never runs at all. The flag's real job is untouched. It guards the SECOND read within one request, where a body arrives after its headers and slices into the array are live; readRequest clears it on entry and raises it once the header block is parsed, so it covers exactly the window in which a Request exists. This point is outside that window by construction. Pipelining is also unaffected: the available() == 0 term still sends a buffer with bytes left in it down the copying path. BackendHttpIntegrationTest passes 21/21, including transactionRollsBack and authGuardsMutatingRoutes -- the two this guard broke when it was missing -- plus pipelinedRequestsAreNotLost, chunkedUpload and honoursExpectContinue.

The route falls from 168.2 to 88.2 bytes per request and Request disappears from the allocation profile entirely; that half is exact rather than statistical. Throughput over thirteen interleaved pairs in one binary, arm order rotating, is a median +13.6%, ahead in 12 of 13, p99 better in 10 of 13. A profiled build shows +2.3% for the same change and that is not a contradiction: the profiler taxes every allocation, so that server is slower, allocates less per second, and the collector it is being spared matters less. Immutability is preserved where it was actually claimed. The class documents a Request as valid only for the duration of Handler.handle, and the array and slice table behind it were ALREADY reused; the fields simply stop being final so one object can be re-pointed. reset() runs while a request is being parsed -- after the previous handler returned and before the next is called -- so nothing mutates under a handler, which is what "immutable to its handler" meant. Every field is assigned with no unchanged case, headers most of all: it caches a Map built on demand, and carrying it over would answer one request's header lookups with another's.

The response head's literals -- "HTTP/1.1 ", "\r\nContent-Type: ", "\r\nDate: ", "\r\nContent-Length: ", "\r\nConnection: keep-alive", "\r\n\r\n" -- are 82 of the ~97 characters a plaintext 200 emits, so the server was spending 51 million charAt calls a second at its own throughput to reproduce bytes that never change. fasthttp writes pre-encoded slices with copy. These are encoded once at class init and written through put(byte[]), which is a System.arraycopy, and status 200 gets its whole line as one constant so the number formatting goes too. Aimed by measurement rather than by reading the code. CPU accounting from /proc//stat, which perturbs nothing, put CN1 at 1.36us of USER time per request against fasthttp's 0.74us while SYSTEM time was at parity, 1.62 against 1.51 -- so the I/O pipe was already equal and the whole gap was work we do ourselves. Two earlier candidates died on measurement first: strace showed nothing useful and distorted fasthttp by 27x, and the "we send Connection: keep-alive and Go does not" theory turned out to be worth six bytes, because fasthttp sends a Server header we do not. Measured, three interleaved pairs with the arm order rotating, one binary: throughput 566719 against 519456 req/s, +9.1% and ahead in all three; user CPU 1.36 -> 1.20us per request; system CPU unchanged at 1.6, which is the shape the diagnosis predicted. The remaining user-CPU gap to fasthttp is 0.46us from 0.62. Responses are byte-identical between the two paths, asserted by md5 over headers and body with only the Date line excluded, before any timing was taken. CN1_HTTP_FAST_HEADERS=0 restores the per-character path; both are complete and independent so the comparison stays runnable. BackendHttpIntegrationTest 21/21.

FREEING THE THREAD STATE. markDeadThread only QUEUES a dying thread's TLD; cn1DrainDeadThreadPending migrates its pending allocations at the next mark and frees the TLD only if gcReleaseRequested is set. An OS thread gets that flag from its Thread object's finalizer, and cn1RetireVirtualThread -- the VM's own retirement path -- sets it explicitly because a virtual thread has no such object. The backend's freeImpl duplicates that path and did not, so every connection's TLD was queued, drained, un-flagged and abandoned: callStack arrays ~50KB, pendingHeapAllocations ~27KB, the try-block array ~15KB, all malloc'd. Measured at ~68KB per closed connection, resident memory 3MB to 65MB over 900 connections, and 249 collections returned none of it because every drain found the flag clear. DRAINING IT. That queue is only drained at mark start, so a server that churns connections while allocating almost nothing has no reason to collect and no other way to reclaim -- a sawtooth to 165MB over 2800 closed connections. Queued thread state is now its own demand signal. Allocation volume cannot express it: none of that memory was allocated by the mutator, so the counters the trigger watches never move. With both halves, resident memory is flat at ~34MB across 3200 closed connections where it previously reached 165MB. REQUEST.RESPOND. Response was the last per-request allocation on a route that allocates nothing else, and allocation drives both how often the collector runs and how much it holds. A handler can now ask the request for its connection's Response instead of building one. Valid for the duration of handle() and not beyond, which is the contract Request already carries and for the same reason; new Response(...) is unchanged for a handler that needs its own, and the HTTP/2 path, which has no connection to borrow from, still allocates. Verified before timing: pooled and allocating emit identical bytes across three requests on ONE connection, which is where a stale field would show and a single-request check would not. BackendHttpIntegrationTest 21/21 including pipelinedRequestsAreNotLost, dtoRoundTrip and headersAndCookiesBind; GcHeapIntegrity, BibopPageFloor, LowMemoryThrottle and LargeArrayGc 4/4 against the collector change.

Each host thread now counts into its own slot, spaced a cache line apart so two hosts never share one, and the health endpoint sums the stripes. The slot has a single writer -- the host that owns the connection -- so the increment is a plain add, and the index is resolved once per connection rather than per request. The reactor mode keeps the atomic: it has no hosts to stripe by. Measured, interleaved, one binary apart: 605832 against 582037 req/s (+4.1%), p50 97 against 101.5us, and user CPU 0.988 against 1.090us per request -- so the atomic was costing about 100ns of the 320ns that separated this server from fasthttp in user time. BackendHttpIntegrationTest 21/21 including metricsEndpoint, which reads the striped total. Worth recording how it was found: the candidate list going in was parsing, write barriers, safepoint handshakes and bounds checks. The barrier was measured at zero, and none of the others were this. The profiler named it in one run after several hours of ablation guessed at everything except a metrics counter.

It was the ONESHOT re-arm: the kernel disarms a descriptor as it delivers it, so every park cost an EPOLL_CTL_MOD to bring it back -- one syscall per request, on a path whose dominant cost is already syscall dispatch (musl's __syscall_cp_c, 19% of in-binary self time). ONESHOT was guarding a hazard that only exists when several threads share a poller, and virtual-thread mode has affinity instead: a descriptor lives in exactly one host's epoll set and that host is not polling while it is inside advance(). But it was also doing something the comment did not credit it with. A virtual thread that answers RUNNABLE is queued in the ring, neither running nor parked, and ONESHOT's disarm-on-delivery is what stopped epoll reporting it again and having advance() resume a handle the ring was also about to resume -- a use-after-free once the first resume finishes and frees it. That invariant is now explicit: the RUNNABLE path removes the descriptor and VtHost.armedByFd remembers it, so the syscall moves to the yield path instead of every request. Measured on two pinned cores, interleaved with rotating arm order, n=3: new 650505 rps p50 73us p99 199us 2.40 us/req cpu old 609484 rps p50 96us p99 162us 2.62 us/req cpu fasthttp 608615 rps p50 88us p99 903us 2.32 us/req cpu +6.7% throughput and a quarter off p50, with no overlap between the arms. That puts the plaintext path at 1.069x fasthttp's throughput and 4.5x its p99, at 3% more cpu per request. BackendHttpIntegrationTest is 21/21, which exercises this: build.sh always defines CN1_VIRTUAL_THREADS, so those run in virtual-thread mode over kqueue, including shedsIdleConnections and the park/timeout path.

It came from comparing raw buffer bytes against String constants one character at a time: about eleven calls per request before a single header is read -- eight for the version and three for the method -- and more for every header name matched. The constants are now held as byte[] built once at class initialisation, so the same comparison is a byte load. The folded comparisons keep their constants ALREADY folded, which halves that work again: only the bytes that arrived off the socket are passed through foldAscii, instead of both sides on every character. knownMethod was also doing the same walk twice. It asked for a folded match AND an exact match, and an exact match implies the folded one, so the first call could only ever agree with the second -- two passes over the method with a foldAscii per character to answer what one pass answers. Interleaved with rotating arm order, n=3, against the previous commit: byte constants 659698 rps 2.371 us/req cpu previous 652597 rps 2.393 us/req cpu fasthttp 610101 rps 2.307 us/req cpu Throughput ranges overlap at n=3 so the +1.1% is not separated, but the cpu figure is lower in three reps of three, which is the effect the profile predicted: charInternal was about 1.8% of total cpu. Behaviour is unchanged where the folding matters. Ten probes against both binaries -- upper, lower and mixed case Content-Length and Transfer-Encoding, HTTP/1.0, HEAD, an unknown method and a lower case one -- answer identically, including the 501 for "get", because HTTP methods stay case sensitive.

Nothing shrank it, and the take-side staging buffer inside cn1SatbTake grew the same way, so a process that saw one busy period kept both at the peak for its whole life. Measured on the backend, with gcSatbTop read as 0 every time it was sampled -- none of it was in use: plaintext satbCap 8MB of a 12MB RSS /json DTO route satbCap 16MB /json map route satbCap 8MB Two thirds of the plaintext process was an empty write-barrier log. It is also what made the footprint look unrelated to anything else: the run with the FEWEST BiBOP pages had the MOST resident memory, because it was the one whose barrier traffic had reached 16MB. Trimmed in the sweep, beside the page trim, against the high-water batch since the last trim rather than the instantaneous depth -- which is 0 there by construction and would shrink to the floor every cycle and re-grow through several reallocs on the next burst. The 4x slack and doubling target mean a steady workload settles at a size it keeps. Only shrinks when the log is idle: a non-empty log is live data the mark phase has not taken yet. A failed realloc keeps the existing buffer, because realloc is not required to succeed just because the block is getting smaller. Interleaved with rotating arm order behind a calibration gate, n=3: /json RSS 57.7MB -> 24.1MB 590056 rps against 587744 /plaintext RSS unchanged 647380 rps against 646246 Throughput is unchanged on both routes; the memory is 58% off the allocating one. Plaintext does not move because response pooling runs one collection per 15s, so the trim almost never fires there. GC gate: GcHeapIntegrity, GcOverflowSpiral, GcUncooperativeThread, LargeArrayGc, BibopPageFloor and the 21 BackendHttpIntegrationTest cases all pass. GcSteadyState's 768MB-ceiling scenario fails, and fails IDENTICALLY with this change stashed (895.8s against 913.7s, same 600s timeout, same scenario) -- it is the known local failure on this 16-core machine, not a regression.

What it did not avoid was the Response itself. Response.jsonValue is a static that allocates one per call, and that was the ONLY thing the route allocated. Profiled with -DCN1_GC_CONFORM over 10.9M requests on the DTO route: 88.1 bytes/request, and the histogram has one row that matters -- com.codename1.backend.HttpServer.Response bytes=961269408 count=10923516 count is one per request. The plaintext route had been pooled already and sat at 0.1 bytes/request. Request.respondJson puts the JSON route on the same footing: the connection's pooled Response, reset and re-pointed at the value. That takes the route to 0.1 bytes/request, and with nothing to collect the collector stops running: ZERO cycles in a 15s run against 205. Which is the whole point -- the collector shares the server's cores, so on this machine a route that allocates pays for it in its tail, not in its allocator. Production build, interleaved with rotating arm order, n=3: rps p50 p99 cpu/req RSS gc cycles pooled (3) 672158 72us 178us 2.33us 10.6MB 0 unpooled (2) 600949 89us 2843us 2.59us 22-27MB 205 fasthttp 592709 96us 1347us 2.51us 12.3MB - 1.134x fasthttp's throughput, 7.6x its p99, less cpu per request than it spends, and a smaller resident set. For reference fasthttp is not allocation-free here either: GODEBUG=gctrace=1 over 11.4M requests shows 60 collections, 3->3->0MB each, about 16 bytes per request. Mode 2 stays exactly as it was so the cost of the Response remains measurable against mode 3, and mode 0 stays the default -- it is still the honest cost of a handler that hands back a Map. reset() already clears deferredJson and hasDeferredJson, so a pooled Response reused for a plain body cannot carry a stale value into the next response. BackendHttpIntegrationTest 21/21 and BackendDatabaseTest pass.

The only reason it resolved here was an install run by hand into a per-checkout repository months ago. That matters because BackendPackageMojo resolves the artifact at run time: resolve("com.codenameone", "codenameone-backend", ...) so on a fresh clone, in CI, and in a release, cn1:backend-package and cn1:backend would fail to find a runtime that the build never produced. Placed after sqlite-jdbc, its only dependency. Verified by deleting the hand-installed copy first and building the module from the reactor: all four artifacts come out, including the parparvm-sources classifier the package goal needs. Note for the release: this now publishes codenameone-backend alongside the other modules, which is the point -- an app cannot depend on a runtime that is not published.

The skeleton in common.zip now carries a backend module beside the platform ones, with a working handler rather than an empty directory. It is not built by default. The module sits in a profile activated by -Dcodename1.platform=backend, the same shape the platform modules use, so a client-only download pays nothing for it. GeneratorModel validates the new module's coordinates like the others but deliberately does NOT require a dependency on the generated common module -- and the test asserts that dependency is ABSENT. common is compiled against codenameone-core, a server has no display, and requiring it here would enforce exactly the mistake the module's own comment warns against. Verified against the real zip by mirroring what the generator does: apply the same content and path substitutions, normalize whitespace the way normalizedPom does, then assert the fragment validateModulePomCoordinates looks for. The coordinates resolve to :-backend:1.0-SNAPSHOT, the handler lands at backend/src/main/java//BackendServer.java with its package rewritten, and the root pom keeps balanced profile tags. The initializr's own suite could not be used for this: every test class in that module reports "Tests run: 0" locally, pre-existing and not specific to these sources, so the assertions added here get their first real run in CI.

The initializr's copy of this handler deliberately does NOT get one: its template sources live inside common.zip, are not tracked as source, and none of them carry a header -- MyAppName.java in barebones-src.zip opens on its package line. Each path keeps its own convention rather than inventing a third. Re-verified after the edit: the archetype still generates, the package line lands at 23 under the header, and the generated backend module still compiles.

Validated like a platform module, with one check inverted. The platform modules must depend on the generated common module; the backend module must NOT, because common is compiled against codenameone-core and a server has no display. So the common-dependency assertion is turned off for it and replaced by its opposite -- finding that dependency there is now a failure rather than something the script is silent about. This is the third place that had to learn about the module, after GeneratorModel's runtime guard and the matrix test. All three now agree on the same rule. Verified by running the whole scaffolding-integrity job locally: embedded coordinates, generated repositories, and the archetype/initializr settings parity check (39 hint entries in sync).

From afb912781380df93a4db0d4404f3ca076d750e35 Mon Sep 17 00:00:00 2001 From: Shai Almog Date: Tue, 8 Sep 2026 14:14:12 +0300 Subject: [PATCH 064/167] Make the backend chapter a chapter rather than a pitch The first version argued for the backend and taught nothing: no project layout, no code, no architecture, no numbers, and nothing about the concurrency model that makes the thing work. Rewritten around what a reader actually needs. Added: * Two diagrams. One shows the build pipeline and the request path -- Java to bytecode to C to one binary, then connection to host thread to virtual thread to handler. The other is a slope chart of p50 against p99 on a log scale, because the tail is the interesting part and a table hides it. * A first server: the generated module layout, the handler the archetype emits, and what the three non-obvious lines in it do (shutdown draining, answering off the pooled Response, awaitTermination). * Virtual threads and the request loop: one virtual thread per connection rather than a pooled worker per request, one host thread per core, descriptor affinity as the reason the scheduler needs no locks, and the measured 16-hosts-versus-2 result that fixed the host count to cores. * A database section, and a fullstack section showing one @RestClient interface generating the app's async client and the server's sync half plus dispatcher. * Measured numbers instead of adjectives, from the harness in the repository. The measurements, two pinned cores and 64 connections, medians of three interleaved runs: req/s p50 p99 cold start resident native musl 595,610 0.090 ms 0.249 ms 0.77 ms 10-40 MB native glibc 547,761 0.065 ms 4.06 ms 2.88 ms 14 MB Go fasthttp 496,293 0.104 ms 2.63 ms 2.39 ms 6.3 MB same code, JVM 187,745 0.260 ms 1.60 ms 82.5 ms 190 MB The JVM row is the same handler and the same protocol source, run through impl/javase instead of impl/parparvm, so the difference is the runtime underneath and nothing else. Cold start is the column that matters: under a millisecond against 82.5, which is the whole serverless argument. The chapter also says plainly that the tail follows allocation rate rather than the runtime badge -- the flat musl line is a route that allocates 0.1 bytes per request, and the same server allocating a map per request has an 80 ms tail. GraalVM is named as absent and why: this handler cannot run on it, since the runtime's natives are ParparVM's, so a comparison would be a different server against a different framework reported as a toolchain result. Gates: vale 0 across the guide, LanguageTool 0 (status=ok, run against the rendered HTML on JDK 17), asciidoctor clean at --failure-level WARN, structure, snippets, code blocks and unused images all pass. epoll and microbenchmark added to the LanguageTool accept list as real terms its dictionary lacks.

For +most server work that assumption holds.

A translated binary has no class loading to do, no bytecode to -verify and no warm-up before it reaches steady state, so it starts in milliseconds -rather than seconds. It has no JVM heap to reserve, so its resident set is a few -megabytes rather than a few hundred. It's one file, so the container that holds -it can be empty apart from that file. - -Those properties matter in a specific region of the server-side map: short-lived -processes, per-request billing, memory-capped instances, sidecars, edge locations -and small always-on services. Java is thin on the ground there. The JVM's start-up -cost is charged on every cold invocation, its baseline memory is charged for the -life of the instance, and neither cost can be amortised by a process that exits -after a few hundred milliseconds. Teams therefore reach for Go or Node, and a -Java shop that does this ends up maintaining a second language, a second -toolchain and a second copy of every model object that crosses the boundary. - -The backend is aimed squarely at that gap. It doesn't try to win the territory -the JVM already holds; it tries to remove the reason a Java team has to leave Java -when it steps outside that territory. - -=== Full vertical integration - -Where the backend is most valuable is where the client is a Codename One app, -because then both ends are the same language, the same build and the same -contract. An interface annotated for the REST client generates the app's typed, -asynchronous client. Enabling the server half generates, from that same -declaration, a synchronous interface the backend implements and a dispatcher that -routes a method, path and body to it. - -One declaration produces both ends. A change to the contract becomes a compile -error on whichever side hasn't followed it, rather than a response the app fails -to parse in the field. The data transfer objects are shared rather than -transcribed, and their codecs are generated on both sides, so there is no hand -written mapping layer to drift. - -The server half is off by default, because existing projects carry these -interfaces for their client alone and generating server classes into those builds -would grow them for nothing. Turn it on with a property: +A JVM charges you twice. It charges start-up on every cold process, and it +charges a baseline heap for as long as the process lives. Both are fine when a +service runs for weeks and handles millions of requests. Neither is fine when the +process exits after 200 milliseconds, when you are billed per invocation, or when +the instance is capped at 128 MB. + +That describes a specific and growing slice of server work: serverless functions, +sidecars, edge workers, webhook receivers, small always-on services. Java is thin +on the ground there, and the reason is arithmetic rather than taste. Teams +therefore reach for Go or Node, and a Java shop that does this ends up with two +languages, two toolchains, and two definitions of every object that crosses the +wire. + +The point of the backend is to remove the reason to leave Java for that slice.

Not a pooled worker that a connection +borrows for one request -- a stack that belongs to that connection until it +closes. The handler can block on a socket read, a database round trip or a file, +and it costs a parked stack rather than an OS thread. -| TLS -| Termination for inbound connections and verification for outbound ones. +Host threads run those virtual threads, and there is one host per core. A +descriptor is registered in exactly one host's epoll set, so it can only ever be +reported to that host, and only that host ever touches its virtual thread. That +affinity is why the scheduler needs no locks on the hot path. -| Databases -| SQLite in-process, and PostgreSQL and MySQL over their wire protocols, behind a - pooled connection API. No JDBC driver is involved. +The loop is: the host polls, a descriptor becomes readable, the host resumes that +connection's virtual thread, the handler runs until it needs bytes that haven't +arrived, and it parks. Parking returns control to the host, which polls again. +When the handler finishes a response the descriptor stays armed, so the next +request on that connection costs no system call to set up. -| Serialisation -| A JSON reader and writer that works against a byte sink rather than building - intermediate strings, plus Base64 and its URL-safe variant. +Host count follows cores rather than the `workers` argument. On two pinned cores, +16 hosts served 117 requests where 2 hosts served 257,297: past one host per core +they compete for the cores the server needs. In this mode `workers` stops meaning +"requests in flight," because the virtual threads supply that. -| Identity -| JSON Web Token signing and verification. +=== Talking to a database -| Serverless -| An AWS Lambda custom runtime loop. -|=== +`Database.open` takes a SQLite path or a PostgreSQL or MySQL URL, and the rows +come back as the same Java types either way: + +---- +Database db = Database.open(System.getenv("DATABASE_URL")); // or ":memory:" +db.execute("CREATE TABLE IF NOT EXISTS note (id INTEGER PRIMARY KEY, body TEXT)", + null); -Anything outside that list isn't there. There is no dependency injection, no -object-relational mapper, no template engine and no admin console. +List rows = db.query("SELECT id, body FROM note WHERE id > ?", + new Object[] { Integer.valueOf(10) }); +---- + +There is no JDBC driver involved. SQLite is linked into the binary, and the +PostgreSQL and MySQL clients speak their wire protocols directly. `DbPool` holds +connections when more than one request needs the database at a time. -=== Running it locally +=== Sharing the contract with the app -During development, run the handler on the JVM. It starts in about two seconds -against the minute and a half a native build takes, and because the runtime is -ordinary Java compiled against the JDK, the classes underneath the handler are the -only thing that differs from the deployed binary: +This is where having the same language on both ends stops being a slogan.

It's the same source that ships, so -behaviour here matches the deployed binary. The one deliberate exception is TLS: -the local runtime doesn't terminate it, and therefore doesn't serve HTTP/2, and -both refuse with a message saying so. A second handshake implementation would have -its own defects rather than production's, which is worse than not having one -because it resembles coverage. When TLS is what needs exercising, build the binary. - -=== Packaging a native binary +Building the backend module with `-Dcn1.restServer=true` generates two more types +from that same interface: `NotesApiServer`, a synchronous interface the backend +implements, and `NotesApiDispatcher`, which routes a method, path and body to it +and binds the path and query parameters. ---- -mvn cn1:backend-package +public class Notes implements NotesApiServer { + public Note note(String id) { ... } // no callback: this IS the server + public Note create(Note note) { ... } +} ---- -The translation runs once and the compile runs per target.

HttpServer, two request-smuggling boundaries: * Whitespace before a header colon was trimmed away, so "Content-Length : 5" became a valid Content-Length here while an intermediary in front rejects that line or reads it as a different field. RFC 9112 5.1 says a server MUST reject it, which is what the obsolete-folding check beside it already does. * Transfer-Encoding was decided per field with a substring test, so a second Transfer-Encoding overwrote the first and an unsupported coding was ignored entirely -- either one leaves the body to be read as the next request. Every instance is now joined and the list must end in chunked, with anything else refused rather than framed on a guess. StaticFiles: a configured prefix of /assets matched /assets2/logo.png and stripped it to /2/logo.png, serving from the document root a URL outside the namespace the handler was mounted on. The prefix now has to end on a segment boundary. Json: the String-returning writer left Short and Byte out of its numeric branch while the ByteSink writer had them, so the same value was 1 through one API and "1" through the other. RestServerAnnotationProcessor, three: * A Set-typed @Body was bound by casting bodyAsList's ArrayList to Set. That is the cast the file's own comment warns about -- the JVM throws before the handler runs and the translated target does not check at all. It converts now. * Percent escapes were appended one character per octet, so %C3%A9 arrived as two characters instead of one accented letter. Consecutive escapes are gathered and decoded as UTF-8. * Float, Short and Byte DTO fields fell through to guardedCast, which returns null because the JSON reader only ever produces Long or Double, so valid client values were dropped silently. BackendPackageMojo: the translator received only JavaAPI and this goal's own output, never the module's dependencies. A backend using a type from a shared contract module compiled -- javac had it on the classpath -- and then failed to translate, which is the DTO-sharing arrangement the generated project recommends. BackendJavaSeRuntimeTest: skip rather than fail when the local repository has no codenameone-core for generate-contract.sh to build against. vm-tests does not install it, so the failure was an environment gap; this routes it through the same skipOrFail the database tests use, and CN1_BACKEND_REQUIRED still turns it back into a failure where the backend is meant to run.

The response body was one buffer on the SESSION, and nghttp2 reads a body after submit returns, while it pumps output. serveHttp2 submits every finished response before it drains, so when two streams completed in one receive cycle the second submit freed the first one's buffer and reset the shared offset: whichever body was submitted last went out for both streams, or an empty one did. Concurrency is the entire point of HTTP/2, so this was not an edge case. Each response now owns its buffer, carried in the data provider's own source pointer -- which is what nghttp2 offers for exactly this and which the code was setting to NULL. The session keeps the list so a stream reset before EOF frees rather than strands, the read callback frees at EOF, a resubmission for the same stream releases the previous buffer, and teardown drains whatever is left. Separately, the DATA callback grew that buffer with no ceiling while both HTTP/1 framing paths refuse a body over 8MB. A peer could stream DATA on one stream, or on each stream its SETTINGS allows, until the process ran out of native memory -- the limit was only as good as the protocol the client picked. HTTP/2 now enforces the same 8MB and resets the offending stream rather than failing the callback, so one oversized upload does not take the connection's other streams with it. Verified by building the native binary (the C compiles against nghttp2) and running BackendHttpIntegrationTest, 21/21, which covers the HTTP/2 paths.

An attacker who can write a symlink under that root controls what happens between those two lookups -- point it outside for the open, inside for the check, and the descriptor that gets served is the outside file while the check passes. Comparing st_dev/st_ino after the fact narrows the window without closing it, because that comparison needs the same racy second lookup. openat2 with RESOLVE_BENEATH moves the decision into the resolution itself, so there is no window to lose: the kernel refuses a path that escapes the directory while it walks it, and a descriptor that exists is already known to be contained. Not every target has it -- it wants Linux 5.6, and the local Java SE loop has nothing equivalent -- so openBeneath answers -2 there and the caller keeps the old open-plus-realPath path rather than treating a refusal as a missing file. The JavaSE implementation says so in as many words rather than reimplementing the race in Java and looking like it checked something. RESOLVE_BENEATH is defined locally rather than pulled from linux/openat2.h, which older distributions do not ship, and an old kernel that knows the syscall number but not the struct answers EINVAL/E2BIG and is treated as unsupported. Verified by building (the signature verifier runs strict, so the native name is right or the build fails) and by BackendHttpIntegrationTest 21/21, which exercises static file serving in 40 places -- this changes the open path for all of it.

Gathers the octets and decodes the run, which is the same fix the annotation processor already had. - RestServerAnnotationProcessor converted a List to a Set in fromBody but not in fieldFromJson. Codex named the java.* branch; enumerating the call sites found the DTO branch had it too. - HttpServer read a chunk-size line and trailers without a bound, so a peer that never sent the terminator grew the buffer without limit. Both are now held against MAX_HEADER_BYTES. - HttpServer accepted duplicate Host headers, which is a request-smuggling vector against a downstream proxy. Counted in the existing header walk, so it costs nothing. - Json had no depth limit, so deeply nested input overflowed the stack. - DbPool could hand out or retain a connection after close(). - S3 captured a temporary role credential at startup and signed with it forever. Re-resolves near expiry, but only when we resolved it. - S3 CreateBucket sent an empty body, which asks for us-east-1 whatever the region says. Sends a location constraint outside us-east-1, and keeps the empty body for the S3-compatible endpoints that require it.

The Lambda Runtime API client read to EOF and called everything after the header terminator the body. Connection: close ends a message but does not remove chunk framing, so a chunked reply would have handed the handler size lines and terminators mixed into its input. Decodes it now, and treats a coding it cannot undo as an error rather than passing the framed bytes through -- the handler would otherwise parse garbage and blame its own input. The other two read as guide-versus-code mismatches, and the guide is already right: "Limits worth knowing" states that packaging compiles Java and that Kotlin is therefore not wired into this path, and the deployment section attributes the cross-compiled targets to package.sh in this repository rather than to the goal. What was actually wrong was what a developer hits: - A Kotlin main class failed inside the translator, which names neither Kotlin nor the reason. Checked after the compile instead, where the message can say what happened. Reusing Maven's jar would fix Kotlin by giving up the bootclasspath compile that keeps a backend off classes the runtime lacks, so the check explains the trade rather than removing it. - cn1.backend.target pointed at a repository path a generated project does not contain. Still a loud failure, since ignoring it would return a host binary labelled cross-compiled, but the message now says where the script lives and what to do without it.

The HTTP/2 path returned response.body and never looked at it, so a handler that worked over HTTP/1.1 answered HTTP/2 with an empty body. - stop() closed the TLS and HTTP/2 session objects at the drain deadline and nothing else. A plaintext connection is in neither map, so its socket stayed open while the server reported itself fully stopped. Every accepted descriptor is tracked now and closed through drop(), which is the one place that releases the sessions, the descriptor and the count together. - parseColumn stopped reading before the MySQL flags, so the UNSIGNED bit was never seen and every integer was decoded at one fixed signedness: a signed TINYINT of -1 read back as 255, a SMALLINT UNSIGNED of 65535 as -1. Silent wrong rows, which is the worst shape for this to take. - A Range was honoured whatever If-Range said, so a resumed download could staple bytes from a changed file onto a stale prefix and look complete. The last two were one bug each with a wider cause than the report: - The generated decoder turned '+' into a space everywhere. That is form encoding, which a query string and a cookie are and a path segment is not, so /items/a+b reached the handler as "a b". Split in two rather than parameterised at the call sites, so the wrong one is harder to reach for. - A Set returned from a contract method was written as its quoted toString(). Fixed in Json rather than in the generator: converting at the one generated expression would leave a Set reached through a Map or a DTO field still wrong, and both writers now emit any Collection as an array.

HTTP/1.1 uses the first and HTTP/2 the second, so one handler returned a readable BLOB over one protocol and "[B@1a2b3c" over the other. - The JavaSE Db captured the insert id only for a prepared statement, so an INSERT with literal values reported the id of some earlier insert while the native implementation answered last_insert_rowid. captureInsertId only assigns when the driver returns a key, so a PRAGMA cannot clobber it. - Cookie values were decoded as form data, turning a literal '+' into a space.

That is twice the file's size in memory for one request, and a large enough public file made it an OutOfMemoryError, which the surrounding catch(Exception) does not catch because it is an Error. A response body may now be a descriptor instead of a buffer. The provider preads each frame straight into nghttp2's own buffer, so the memory is one frame whatever the file's size and nghttp2's flow control sets the pace. pread rather than read because two streams may be serving the same file. The descriptor becomes the session's on submit and is closed in one place, which covers EOF, an early stream reset and teardown alike; the failure paths close it before returning, since nothing else would. A file shorter than its Content-Length ends the stream rather than stalling, which the client detects as a short response. The signature gate did not cover the backend, and adding it revealed why that mattered: maven/backend/target/classes holds the JavaSE half, which has no natives at all, so the obvious entry checked nothing while reporting a pass in the same words as a real one. The script compiles the ParparVM half itself now. It sees 249 native methods where it saw 149, and dropping one underscore from the new symbol fails it -- which is what the gate is for, given neither the compiler nor the linker would have said a word.

The first is mine, from the streaming change one commit ago. - HTTP/2 session teardown freed each pending body directly instead of going through the release helper, so a file-backed body's descriptor was never closed. A client that dropped the connection mid-download leaked one per request until the process could not open files. Both paths now free through one function, so a body cannot be released without its descriptor. - drop() was not idempotent, and the stop() deadline gave it a second caller: the deadline closes a connection a worker may still be using, and that worker calls drop again on its next failed read. The second call decremented the open count again and closed a descriptor number the OS may have reused, shutting down unrelated I/O. Winning the removal from liveConnections now decides which call owns the teardown, and a connection is registered before it is armed so the poller cannot report one this map has not heard of. - The folded header-name cache filled a shared 512-byte store end to end and wrapped without retiring the slots it was about to overwrite. Thirteen long names was enough for "content-length" to stop matching itself, which makes getHeader report a header that was sent as absent -- verified against the old code, where the probe fails. Each slot owns its bytes now. - MySQL packets are 24-bit-framed. A body of 16MB or more was sent with a truncated length followed by the whole payload, so the server read the remainder as headers and the connection desynchronised rather than failing. Sent in full-length packets with running sequence numbers now, terminated by an empty one when the length divides exactly, and reassembled on the way in. - An absolute-form target with no path lost its query entirely, and a '/' inside a query value was read as the start of the path. - createBucket treated BucketAlreadyExists as success. Bucket names are global on AWS, so that response means somebody else owns it: the caller got a success for a bucket it does not have. - The generated backend modules ship sqlite-jdbc. It is optional in codenameone-backend, so Maven does not pass it down, and the guide's Database.open(":memory:") failed under cn1:backend with "No suitable driver".

A database URL's ten-second default therefore meant ten seconds in the JavaSE runtime and nothing at all on the device, so the same misconfiguration reads as a slow start in development and a hung process in production. Non-blocking connect with poll, and select on Windows. - SIGPIPE was only ignored as a side effect of Signals.installShutdownHandler, which a server need never call. Its default action is to kill the process, and send() raises it when a client goes away mid-response, so a browser tab closing at the wrong moment took the server with it. Ignored at bind, where a server that listens cannot skip it, and MSG_NOSIGNAL on the write where the platform has it. - An HTTP/2 request with more than 64 fields silently kept the first 64 and returned success, so the handler saw a request with a cookie or a tracing header simply missing. The stream is reset now, which is what HTTP/2 has in place of HTTP/1's 431. - A suffix range over an empty file came back as a satisfiable {0, 0} and produced "Content-Range: bytes 0--1/0", which no client can read. Every range over a zero-length representation is unsatisfiable. - cn1:backend-package created its work directories without emptying them, so a renamed or deleted source left its old .class behind for the translator to read -- and requireMainClass would accept a main class the module no longer had, packaging the previous implementation. - The demo borrowed one pooled connection at startup and shared it across every request. The rest of the pool went unused, and statements from one request could land inside another's transaction: a plain addPet could be rolled back by an unrelated addPets that failed. Each operation borrows and returns its own now, with the insert and lastInsertId kept on one connection because the id belongs to the connection that did the insert. The in-memory case still shares one, since a second connection to ":memory:" is a second empty database.

That suspends the provider until nghttp2_session_resume_data() is called, and nothing calls it, so a single interrupted read left a download open and silent for good. EINTR retries in place; a regular file never returns EAGAIN, so anything else is a real error. - When the response body could not be copied, the response was submitted with no data provider and reported success -- a 200 whose content silently went missing under memory pressure. It fails now. - MySQL's length-encoded prefix stops at 0xffffff. A byte[] parameter of 16MB or more was written with the 3-byte form and a truncated length, so the server read the rest of the value as the next thing in the packet. The outer packet fragmentation added last round does not reach this: the prefix is inside the packet. - A collection body kept the parser's element types, so a List was a list of Longs wearing the wrong label -- a ClassCastException on the JVM and, because ParparVM's CHECKCAST is unchecked, an Integer's fields read out of a Long on the device. Elements convert now, as DTO elements already did. - A directory without a trailing slash served its index at the original URL, so a browser resolved "style.css" in /static/docs against /static/. It redirects first. - A null content type threw an NPE on HTTP/1.1 and defaulted on HTTP/2, so one handler behaved two ways depending on the protocol. The collection fix came with the test that was missing: the suite only ever covered DTO elements, so this path was never compiled, let alone exercised. Adding it immediately found that the generated dispatcher referred to coercion helpers only the codec had -- it did not compile at all. Reverting the conversion now fails on the element's runtime class, which is what the test is for.

The JavaSE side mapped the UTF-8 bytes into chars and handed them to PBEKeySpec, but the provider ENCODES those chars -- as UTF-8 for PBKDF2WithHmacSHA256 -- so a byte of 0xc3 became two bytes again, while the native side passes the original octets to OpenSSL. A hash written by one runtime then failed to verify on the other, and PostgreSQL SCRAM simply did not authenticate. The comment claiming the mapping preserved the bytes was the wrong half of it. Computed over the raw bytes now, per RFC 8018, and checked against published PBKDF2-HMAC-SHA256 vectors rather than against itself -- including a dkLen past one hash block, which is the part hand-rolled implementations get wrong. ASCII passwords are byte-identical to what the old code produced, so no stored hash stops verifying; non-ASCII ones change, which is the bug. - HTTP/2 lets a client split its cookies across several fields, and the header map overwrote each with the last. A session cookie in an earlier field vanished, so an authenticated request was answered as anonymous. Repeated fields are combined now -- "; " for cookie, "," for everything else, which is what a repeated field line means. - FileIo read its metadata from the PATH while the bytes came from the channel, so an asset replaced between the open and the stat was served with the replacement's length and ETag and the original's content. A descriptor is a snapshot; its metadata is captured with it now. - A @Path naming no placeholder in the route bound null, or 0 for a primitive, and the route still matched -- the handler ran with the wrong identifier and the build said nothing. It is an error now. - Two routes of one verb and shape generate the same predicate, so the second was unreachable however it was called. Also an error, with a test that the same shape under different verbs still passes: the check has to reject the ambiguous case without rejecting the ordinary one. Both processor checks were verified by disabling them and watching the two tests fail, since a validation nothing exercises is indistinguishable from one that does not work.

Four bytes and a "7ffffffd" header was an unauthenticated way to take the process out. Compared by subtraction now, so there is nothing left to overflow. - fill() grows by exactly what it just read, so a body arriving in scratch-sized pieces reallocated and recopied everything once per read: about 4GB of copying for an 8MB upload before the handler ran. The suggested fix was a cached valid-length field, but the class comment records that being built and rejected -- ParparVM mutates the borrowed thread buffer's length in place, so a cached extent breaks silently as truncation. When the total is known, which it is for Content-Length, the destination is allocated once and read into directly instead. buffer.length still means "bytes readable"; no invariant moved. - stop() closed the deadline's connections through drop(), which frees the TLS and HTTP/2 sessions -- possibly under a worker still inside SSL_read. The round-six guard makes teardown happen once; it does not stop that. The descriptor is closed first now, which unblocks the worker so it takes its own connection down on the thread that was using it, and only what no worker claimed is released here. That needed the next finding to work at all: activeRequests wrapped the whole of serveOne, and in virtual-thread mode a worker owns a keep-alive connection for its lifetime and parks between requests, so an idle client counted as an in-flight request and held shutdown for the entire window. A separate counter rather than a redefinition, because the pool sizing genuinely wants the worker-occupancy meaning. - getHeaders() overwrote repeated HTTP/1 fields while getHeader() answered with the first, so a cookie split across two fields was visible through one API and absent from the map a generated dispatcher reads. - The native bind ran the host through inet_pton alone, so "localhost" and every IPv6 address failed startup -- but only once packaged, since the JavaSE side goes through InetSocketAddress and accepts them. Resolved with getaddrinfo now. That forced a second fix: boundPortImpl read the result through sockaddr_in, which on a v6 socket reports a number that was never the port. Verified through the server rather than by reading: a 3MB body arrives intact by length and by content checksum across many reads, and two X-Dup fields arrive combined.

The first is the most serious thing this review has turned up. serveOne made every descriptor blocking. readImpl reaches its park branch only when recv returns EAGAIN, and a blocking descriptor never does -- so in virtual-thread mode the virtual thread never parked on a read at all and the host OS thread sat in the kernel until SO_RCVTIMEO. That is the mode the packaged backend runs in by default, and parking is the whole design. A load generator hides it completely, because the bytes are always already there. Measured on the native binary, sixteen half-open connections against a server with sixteen host threads, three runs each: before 3/5 requests served, slowest 3.995s after 5/5 requests served, slowest 0.001s TLS is deliberately left blocking: Tls.readImpl maps SSL_ERROR_WANT_READ to a hard error rather than parking, so a non-blocking descriptor would break TLS reads outright. Giving that layer a park path is the real fix and is not this change; the limitation is written down where it lives. - A connection that sends nothing never becomes readable, so advance() never ran and the idle deadline it sets never existed -- and SO_RCVTIMEO does not close a socket that is only sitting in a poller. Connections were held until MAX_CONNECTIONS filled and real ones were refused. The clock starts at accept. - The JavaSE runtime had no write deadline at all, so a client that stops reading parked a worker in write() for as long as it liked. The native server has SO_SNDTIMEO for this; writes now go through the same deadline reads do, and progress restarts the clock so a slow-but-moving client is not cut off. - A DTO's collection FIELD kept the parser's element types, so a List arrived full of Longs. Same defect as the collection body two rounds ago, one level in -- the second time I have fixed one site of this and left another. - Resources vanished from the packaged binary: emptyDirs left the private classes directory filled from .java alone, and the project's own output is excluded from the translator input on purpose. Everything except .class is staged in now. Worth recording: none of this is covered by CI. BackendHttpIntegrationTest runs on JavaSE, where VirtualThread.supported() is false, so the whole virtual-thread path is invisible to it, and no workflow builds the native backend. The numbers above come from building it here.

On the From 720e6f7971811978c9bf7edf82b758286dfa0b54 Mon Sep 17 00:00:00 2001 From: Shai Almog <67850168+shai-almog@users.noreply.github.com> Date: Tue, 8 Sep 2026 19:05:54 +0300 Subject: [PATCH 080/167] Backend: address the eleventh codex review round Five findings, one of them a live security hole. A handler that puts request-derived data into a response header -- ordinary code -- could have that value end the field and start another. Demonstrated on the wire: a body of "ok\r\nX-Injected: yes" echoed into a header produced X-Echo: ok X-Injected: yes as two separate fields, which is response splitting and a cache-poisoning primitive. The header is dropped and logged rather than escaped: there is no correct escaping for CR or LF in a field, and a header the handler cannot have meant is not worth sending. Verified both ways -- with the guard removed the probe reports VULNERABLE, with it in place the crafted field never reaches the socket. - The client TLS context cache built entries without a lock, so two threads opening their first TLS connection could take the same slot and interleave the root-name copy with the context store -- an entry labelled for one CA bundle holding the context for another, and a later connection validating against a trust root the caller did not choose. This is server code with real host threads, not the EDT, and the file's neighbours already use pthread mutexes. - libcurl resolves "." and ".." before sending, and SigV4 signed the path unnormalised, so an S3 key with a dot segment was signed for one path and requested at another. CURLOPT_PATH_AS_IS. The JavaSE client does not normalise, so such a key worked under cn1:backend and failed once packaged. - The SQLite bind natives discarded their status. Binding more parameters than the statement has placeholders is SQLITE_RANGE, which was ignored, and the statement still ran with the unbound parameter reading as NULL -- a mutation committed with the wrong values where the JDBC path throws. That meant renaming ten native symbols and five declarations to carry a return; the signature gate confirms the names and BackendDatabaseTest, which builds and runs the TRANSLATED binary, confirms they still work. - The dispatcher compared a raw %5B against decoded annotation text, so @Query("filter[name]") never bound: the generated client and server failed to honour their own shared contract.

The first is the vulnerability I closed last round, through the other argument. Response.contentType is a handler-supplied header value too -- Request.respond takes it, so does the public constructor -- and it went to the wire unchecked while extraHeaders beside it did not. Same demonstration, same result: Content-Type: ok X-Injected: yes as two fields. Validated now at both serialization points, HTTP/1.1 and the HTTP/2 header block, which the native side splits on '\n' and where the same value was a second route in. A rejected type falls back to the default rather than being dropped, since a response with no Content-Type is its own problem. That is the third time in this review I have fixed one call site and left its twin -- after the Set conversion and the UTF-8 percent decoding. The rule is to enumerate the sites, and reading the diff for one is not doing that. - The documented commands do not work. `mvn -pl backend cn1:backend` fails with "Could not find the selected project in the reactor" because the module lives in the codename1.platform=backend profile. The archetype CI step added earlier in this branch passes that property because it had to, which is exactly the evidence that the docs were wrong; I never went back to the line I had copied the command from. Fixed in the archetype root pom, the backend pom, the generated server's javadoc, the guide, and both files inside the initializr archive. - stageResources copied the raw resource directories, which is what a module's / selects FROM, so a file excluded on purpose -- an environment config, a secret -- was packaged into the executable and the later overlay could not remove it. Only Maven's processed output is staged now, and a module with resources but no processed output says so instead of quietly shipping none. - A chunked request truncated after "0\r\n", before the blank line that ends the trailers, was returned as a complete body and handed to the handler. For a mutating request that commits half a message. The fixed-length and chunk-data paths both return null on premature EOF; so does this one.

The commands I corrected there went into XML comments containing "--", which is not well-formed, and both archetype poms stopped parsing. scaffolding-integrity caught the root one; the backend one it does not check, and only a local parse of every scaffold pom found it. This is the same trap that broke archetype generation once already in this branch. Verified by generating a project, not by reading. Then the sweep the last commit said it should have done. Enumerating every write into the response head found a second one: the non-FAST_HEADERS branch writes response.contentType directly, so it carried BOTH defects the fast branch was fixed for -- a null content type as an NPE (round nine) and a CR/LF one as an injected header (round twelve). It is opt-in through CN1_HTTP_FAST_HEADERS=0, but a path kept for measurement is still a path that serves.

TLS servers now run on the thread pool whatever the poll mode says. Tls.readImpl maps SSL_ERROR_WANT_READ to a hard error rather than parking, so a TLS descriptor has to stay blocking -- and a blocking read on a virtual thread holds its host for the duration. With one host per core, one idle TLS client per core occupies every host and unrelated connections stop being served. A pool has a worse ceiling and an honest one. The choice is made once, at construction, so "virtual threads" is a property of the server rather than of the build, and every per-connection site asks about this server; startup says so when it falls back. The outbound read is the same shape and I cannot fix it here. CN1_YIELD_THREAD releases the thread to the COLLECTOR -- it is not a park. The server's own reads park because their descriptors are in a host's poller; an outbound socket is in no poller, so nothing would resume it and yielding would spin. Giving outbound descriptors that registration is a scheduler feature, not a local change, and there is no coverage here to verify one. So it is stated at the blocking call and in the guide's limits, where somebody choosing the mode will see it: a handler waiting on a database occupies its host, and that many concurrent waits occupy all of them. Also: extraHeaders could carry Content-Length, Transfer-Encoding or Connection, which the server writes itself, so a response could give two answers to where the body ends -- desynchronising everything after it on that connection, and poisoning caches when the map came from the request. Refused now. A probe confirms one Content-Length, no Transfer-Encoding, and ETag and Location still served; the static-file tests, which depend on those, still pass. TLS has no coverage in this suite, so the fallback is verified by construction and by the plaintext path continuing to pass, not by a test of TLS itself.

Both WRITE paths were written against a blocking socket and treat EAGAIN as fatal, so from that commit on any response a client read slowly was truncated. Measured on the native binary, 8MB to a client reading 40KB/s: before TRUNCATED after 1414044 of 8388608 bytes (17%), closed at 37.0s after COMPLETE 8388608 of 8388608 bytes in 217.8s The truncation lands exactly where an instrumented build shows the first EAGAIN. Linux sendfile had the identical defect; macOS was already correct, because it reports a partial send as progress rather than an error. Waiting on POLLOUT rather than parking: a park is resumed by the poller and connection descriptors are registered for READ only, so a thread parked on writability would never wake; yielding as RUNNABLE would spin, and advance() clears the idle deadline for a running thread, so nothing would expire it. The wait is bounded by the SO_SNDTIMEO already set per connection. The round-eleven probe could not have caught this: it asked whether OTHER clients were still served -- the property being fixed -- and never whether a large response completes, which is the property being changed. The first probe written for this round could not catch it either: it printed the same sentence whether the server closed early or the probe's own time cap expired, so the A/B read as identical. It now counts body bytes against the expected total and reports COMPLETE, TRUNCATED and BROKE as different outcomes. Also in this round: - HTTP/2 requests left inFlightRequests after the HANDLER rather than after SUBMISSION, so stop() could see no work and free the session while this thread was still about to call into nghttp2. Same use-after-free class fixed for HTTP/1 four rounds ago, in the branch I did not revisit. - Json accepted "+1", "01", ".5" and "1.", none of which is a JSON number, by scanning a character run and letting Java's parsers decide. It follows RFC 8259 now; 19 cases, valid numbers keeping their types including a long past 2^53. - A DTO with a public final field was encoded by the client and silently dropped by the decoder, which cannot assign it after construction. It fails the build instead.

That is the wrong shape to hand anyone, and the hand-written match was also wrong -- `"/healthz".equals(request.getTarget())` builds a String, hashes it and compares it for every route tried on every request, and stops matching the moment a client appends "?probe=1". Routes are methods on an annotated class now. The names are Spring's, under Codename One's packages, so reading one is enough to read the other: @RestController @RequestMapping("/notes") public class Notes { @GetMapping("/{id}") public Map read(@PathVariable("id") long id) { ... } @PostMapping @ResponseStatus(201) public Map create(@RequestBody Map note) { ... } } The build generates a router and an entry point from that, so neither appears in the project. The router holds each route as a byte[] constant and asks the request whether its PATH bytes are those bytes -- no String, no hash, and a query string cannot defeat it -- so a route with no path variables allocates nothing at all. Reflection was never an option: this is translated to C, and Class.forName on an obfuscated name does not survive that. Generated projects ship a controller instead of a server, and their poms name no mainClass; cn1:backend-package takes the generated one and says which. The packaging goal generates into the tree it is about to translate, because the process-annotations goal writes into Maven's target/classes -- a different build, made against a JDK, that the translator never reads. The guide's Java is [source,java] included from a module that compiles it. That is not cosmetic: it is what caught the contract example ending in `public Note note(String id) { ... }`, which is not Java and had never compiled. docs/demos/common could not host these -- it builds for iOS, Android and the browser, and codenameone-backend is a server library. Verified end to end rather than by inspection: a project containing only an annotated class builds, generates its router and BackendApplication, and answers -- /healthz and /healthz?probe=1 both "ok", /greet the defaultValue, /greet?say=X the value, an unknown path 404. Seven processor tests compile, load and CALL the generated router, and removing the one-segment guard from the matcher fails them. Startup lifecycle -- @Configuration, @Bean, constructor injection into controllers, @PreDestroy -- is the next commit. Without it there is nowhere to open a connection pool, which is what main() was doing.

Both regressions this branch shipped lived in what that never exercises, so the gap is closed first and the fixes follow from it. Tests, all against the translated binary over a real socket: - a response larger than the socket buffer, read slowly. Against the code before this commit it receives 548188 of 8388608 bytes. - 64 connections holding a half-written request, while a healthy request must still be answered promptly. - TLS, which had no coverage at all: the handshake, a served request, and the user-space copy that replaces sendfile on an encrypted connection. ALPN negotiation is not covered and says so: this module targets 1.8, where the client API to request a protocol does not exist. And what they and the review found: - the BSD/macOS sendfile branch never retried after EAGAIN moved nothing. It returned 0, sendBody() read that as "the peer is gone", and a large download to a slow client was dropped mid-file. The Linux branch was fixed for this and its twin kept the bug. - HTTP/2 capped how MANY header fields arrived but never how large they were, so a peer stayed under 64 fields and still spent this process's memory a megabyte at a time. HTTP/1 has always refused that. - the TLS ALPN policy lived in a process-global that the last created context won, so a second TLS server changed the first one's protocol. It travels in the callback's own argument now. - @RequestParam/@RequestHeader/@RequestBody documented a `required` element that nothing read: both settings behaved identically and an absent value bound as null. It is enforced, and refused with 400. - ResponseStatus documents that a void method answers 204; the generator answered 200, which made that javadoc wrong about its own default case. - two routes of one shape (GET /notes/{id} and GET /notes/{name}) both compiled, and the second could never run. It is a build error now. Each of the six is covered by a test that fails without it.

That class did not exist, so every one of the self-test's assertions ran only on the JVM -- the arm that does NOT ship. The natives, the GC and the buffer handling are exactly what a JDK-classes run cannot speak for. The missing half is here, building the demo through the real build.sh and asserting the same floor. It is not decorative: reverting the Json change below makes it fail with "FAIL a raw control character in a string is refused", on the translated binary, which is where that parser actually runs. The review round it came from: - System.exit(0) inside the shutdown body deadlocks under the JavaSE implementation, where Signals.onShutdown installs a JVM shutdown hook: exiting from a hook waits for the shutdown it is part of, so `cn1:backend` never returned from Ctrl-C without SIGKILL. Ending the process is the ParparVM implementation's job -- its signal thread has to -- so it moved into both Signals classes and out of all three callers, where the platform difference was invisible. - the route-shape check added earlier only looked within one controller. The generated bootstrap chains the routers and takes the first non-null answer, so two controllers collide exactly as two methods do. The shapes are held across the whole set now. - Json accepted raw control characters inside strings. RFC 8259 requires them escaped, and taking them literally let this parser and whatever validates upstream disagree about where a string ends. - Tcp.read/write handed offset and length straight to recv()/SSL_read(), which index the array through the pointer with no bounds check of their own. The JavaSE arm gets that check free from the stream API, so a bad slice was an exception on the simulator and a native out-of-bounds access only once packaged.

All of them are guarded now: ServerSocket.read/write, Tls.read/write, FileIo.read and Http2.receive, beside the Tcp pair already done. The Java SE arm gets this free from its stream APIs, which is why the same bad slice is an exception on the simulator and a native out-of-bounds access only once packaged. The rest of the round: - the folded-header cache handed back a SLOT INDEX, and the caller then compared against that slot while walking the request's headers. Another worker could retire the slot and write a different name into its bytes in that window, and two names of equal length are indistinguishable, so getHeader answered with the wrong field or reported a header that was sent as absent. It hands back an immutable entry now, published by replacing the array rather than mutating it, so what the caller compares against cannot change underneath it. Still lock free; a lost publish costs one refold. This is the second bug in this cache of exactly this shape. - Json.write(Object) had no Writable branch, so a DTO carrying its own generated writer was emitted as the JSON string of its toString() -- the same handler returning an object over HTTP/1.1 and unusable text over HTTP/2. The third time these two writers have disagreed about a type. - the per-stream HTTP/2 body limit says nothing about how many streams run at once: the advertised concurrency allowed ~800 MiB of native buffers on one connection, every individual request within its limit. There is a session ceiling now. - bodyAsMap/bodyAsList answered null both for "no body" and for "not JSON", so malformed client JSON reached the controller as a null argument and surfaced as a 404, a 500, or a side effect on a value nobody sent. The body is decoded before the call and a request that will not parse is refused with 400. - a null host means every interface, but the default binding created an AF_INET socket, so it could not accept an IPv6 client while an explicitly named host -- which takes the getaddrinfo path -- could. It is a dual stack v6 socket now, falling back to v4 where there is no IPv6.

Under virtual-hosted addressing it lands in front of the endpoint and the result goes straight after "https://", so a name like "attacker.example/ignored" makes the authority the attacker's host and the rest a path -- and the request that follows carries the signed access key identifier and the session token there. Path style is not innocent either: the name goes into the path, where dot-dot walks out of the bucket. Both are checked now, and checked in hostFor and pathFor rather than in send(), because presign() calls those two directly and a check on the send path would have left it open. The two checks differ on purpose. Virtual-hosted addressing gets S3's DNS rules, which it needs anyway to resolve. Path style gets only "one path segment": it is the mode a bucket that CANNOT satisfy those rules uses -- the legacy us-east-1 names with uppercase and underscores -- so applying them there would refuse the buckets the mode exists for. - stop() waited for the in-flight count to reach zero OR for the grace period to expire, and then swept regardless. A handler still inside a request holds the TLS and HTTP/2 sessions that sweep frees, and would write its response through freed native memory. The comment beside it even said "with no request in flight there is no one left to race" -- true of one exit from that wait and not the other. It now returns without freeing anything when the window expires with work outstanding: one leaked session per live connection in a process that is stopping, rather than a use-after-free. - emptyDirs ignored what delete() returned, and the directory not being empty is the entire point: a locked file on Windows or a read-only directory leaves the stale .class exactly where ClassScanner, requireMainClass and the translator all find it, and the build ships a controller that is no longer in the source tree. That is the failure the call site already documents having hit. It checks what survived rather than each delete, so every reason one can survive is covered. The self-test covers the bucket guard on both arms. It found its own first assertion wrong: forEndpoint is path style, so the ordinary-bucket case had to assert the path shape, and the virtual-hosted guard stays uncovered there because forRegion resolves real credentials.

The baseline names AndroidImplementation$46#onReceive; the build now produces $47, because an anonymous class was added earlier in that file and the baseline was never regenerated. The file and the baseline are byte-identical between master and this branch, so any PR cut from master hits it -- master itself never does, because the PR workflow only runs on pull requests. The cast is fixed at the source rather than renumbered in the baseline: the extra is taken as a Parcelable and tested with instanceof, so the entry is deleted rather than moved. The review round: - only HEAD suppressed a response body. RFC 9110 ends a 1xx, 204 or 304 at the header section, so a handler that returns bytes with one of those -- which the Response constructor happily builds -- had them written, and a keep-alive client read them as the start of the NEXT reply. Everything after that on the connection is misframed. Both the HTTP/1 and HTTP/2 paths derive the no-body condition from the status now, and 1xx and 204 also lose Content-Length, which RFC 9110 6.4.1 makes a MUST NOT and which would desynchronise a client just as surely in the other direction. - LambdaRuntime discarded the status of the result POST. The Runtime API ANSWERS rather than throws when it will not take a result -- 413 over the response limit is the ordinary case -- so the handler's work was dropped and the loop went straight back to polling, with the caller waiting for a reply that was never accepted. Both posts check now. - the generated BackendApplication silently overwrote a class of that name already in the controller's package, so the packaged application ran the generated bootstrap instead of the developer's own startup. Refused. - a resource that could not be staged was a warning, and the executable was then reported as built while missing it. The 204 test earns its place the hard way. Written first against the static 304 path it PASSED with the fix reverted, because that path never had a body to write -- so it proved nothing. The fixture now serves a 204 that really does carry bytes, which is what a handler can build, and the test fails without the fix.

Database.execute documents "the number of rows changed", and SQLite and Postgres both answer that, so an update that found its row and altered nothing returned 1 on MySQL alone -- and code reading 0 as "no such row" was told it succeeded. The capability is gone, along with the constant, which nothing else used. - a bucket name may legally contain a dot, and the guard added in the last commit lets one through, but such a name cannot be addressed virtual-hosted over TLS: the wildcard certificate for *.s3..amazonaws.com matches one label, and "photos.example.s3..amazonaws.com" needs it to match two. Every request would fail hostname verification, and so would every presigned URL handed to a client. The addressing is chosen per bucket now, so a dotted name takes the path form instead of failing. Not covered by a test: the self-test can only build a path-style client, because the virtual-hosted factory resolves real credentials. - the guide said DbPool holds connections "when more than one request needs the database", in a paragraph about SQLite, PostgreSQL and MySQL together. DbPool opens SQLite connections from a file path and there is no pool for the wire engines at all, so the advice could not be followed for two of the three -- and following it by sharing one Database is worse than not, since nothing serializes access to that single connection.

Rather than fix that line alone, this asks which socket writes exist in the backend natives at all. There are four: net.c send no flags, no SIG_IGN <- reported server.c send CN1_SEND_FLAGS, SIG_IGN at bind tlsclient SSL_write goes through write(2), where MSG_NOSIGNAL cannot reach tls.c SSL_write same, but covered by the listener's SIG_IGN So three of the four were exposed in a process that neither binds a server nor calls Signals.installShutdownHandler -- LambdaRuntime.run() is exactly that, making only outbound connections. A database or Runtime API peer that went away between one write and the next killed the whole runtime, because SIGPIPE's default action terminates the process. Fixed at connect, which has to precede every write on that socket and covers the TLS client too since it wraps an already-connected handle; MSG_NOSIGNAL is set on the send as well, where the platform has it. Also: the generated path matcher committed to the FIRST occurrence of the literal after a variable, so /download/{name}.json rejected /download/foo.json.json, which it should match with name = "foo.json". It tries each occurrence now and backtracks. The one-segment rule still holds and now ends the search rather than the iteration, since every later occurrence spans the same slash.

Measured with the deadline removed: the server accepted a head dribbled for 20274ms and never ended it. In pool mode -- which is what a TLS server falls back to -- the default sixteen such connections are the entire server. The head now has an ABSOLUTE deadline, armed by its first byte rather than on entry, because a kept-alive connection may legitimately sit idle between requests and that idleness is the socket timeout's business. The head only: a body is bounded by MAX_BODY_BYTES and by progress between reads, and a wall-clock bound there would refuse a large upload over a slow link, which is a real client rather than an attack. - Jwt.issue has always refused a secret under 32 bytes as forgeable and Jwt.verify took any, so the dangerous half failed open: an empty secret let anyone compute a valid HS256 signature over claims of their choosing. It fails closed now, and as an IOException rather than InvalidTokenException, because the deployment is what is wrong and not the token. - a virtual thread carries the accepted descriptor and nothing else, so the Java side finds its server through one process-global. A second virtual-thread server replaced it, and connections the FIRST listener had accepted were then served by the second one's handler and ownership maps. The slot is claimed atomically before the server is built, the loser takes the pool, and the holder gives it back when it stops. That exposed something worse: the constructor RECOMPUTED "am I virtual" from the statics instead of taking the caller's decision, so a server that fell back would have run on a pool while believing itself virtual -- which changes parking, keep-alive linger, ownership and teardown, eight branches in all. It derives from whether a pool was built, which is the actual fact.

A turn that only pumped control frames was never counted by anything at all. There is a second counter for the turn itself, kept out of inFlightRequests because that one is what getMetrics reports as active requests and a flush is not a request. - every submitted HTTP/2 body is COPIED into a native buffer that lives until that flush, so a connection completing many streams at once held all of them: with the advertised concurrency and a large body, hundreds of megabytes of native buffers from one client, on top of the Java ones. The loop drains when enough has piled up. This is the response-side twin of the request-side budget added earlier -- the same shape, the other direction. - absolute-form ("GET http://public.example/p") had its authority stripped and discarded, so a proxy could send it with "Host: internal.example" and getHeader("host") would answer internal.example to whatever routes or authorizes on it. RFC 9112 3.2.2 says the authority wins; a request that carries two different answers is refused rather than silently resolved, because a handler reading the header would still see the losing one. - Router was still inserted unconditionally. The bootstrap got a collision check last round and its siblings did not, so a user class named NotesRouter was quietly overwritten by the generated one. Same check. - a DTO field typed Map collected no codec for the value: only List and Set recursed. The decoder left a plain Map in a field typed as the DTO and the encoder wrote its toString() as a JSON string, both halves compiling and neither working.

The translator always emits cn1_virtual_thread_asm.S and cn1_virtual_thread.c calls cn1VirtualThreadSwitch out of it, vm/backend/build.sh compiles "$SRCDIR"/*.c "$SRCDIR"/*.S, and this loop passed clang only the .c files -- so the link ended with that symbol undefined. Generated resource assembly was dropped the same way. It compiles .S and .s now. Nothing tested this goal, which is why it shipped that way; a test for it needs a full translation plus clang, so it is called out rather than quietly left. - the generated server interface, dispatcher and DTO codec were still inserted unconditionally. The bootstrap got a collision check two rounds ago and the routers one round ago; this is the third family with derived names, and a project class of any of those names was silently overwritten. - "page=zz" for an int bound the annotation's defaultValue, so a client sending a typo got a different page and neither side could tell. RequestParam documents defaultValue as "used when the request omits it", and a malformed value is not an omission -- the same shape as an annotation element nothing reads, which this branch has now fixed three times. It is a 400. The test that asserted the old behaviour asserted it deliberately, so it is updated with the reason rather than deleted. - a literal route and a variable route in DIFFERENT controllers can answer each other's paths. Within one controller generateRouter's comparator already emits the literal first; across controllers nothing orders them, the bootstrap takes the first non-null, and whichever class sorts earlier wins. A router is a set of routes rather than one pattern, so there is no ordering to fix: the ambiguity is reported instead of resolved arbitrarily.

The connect timeout does not cover this: it starts once there is an address. Both resolver call sites yield now -- the outbound connect that was reported and the listener's bind, which has the same shape. Safe across a yield because stringToUTF8 copies into the thread state's own malloc'd buffer; nothing there is a heap pointer. - an HTTP/2 response carried no Date. The HTTP/1 writer sends it, RFC 9110 6.6.1 requires an origin server to, and a handler could not compensate because "date" is refused as server-owned -- so caches computed freshness and age with no server timestamp, but only over h2. - the static-file validator truncated mtime to whole seconds, and its ETag is size plus mtime. A file replaced by different content of the SAME size in the same second kept both halves, so every client holding the old ETag got a 304 for as long as it asked. Milliseconds now; Last-Modified formats from the same value and drops the extra precision, as HTTP dates are seconds. - Db.open accepted any jdbc: URL on the Java SE arm because a driver might be on the dev classpath, and the translated arm hands the same string to sqlite3_open. Code proven through cn1:backend then failed once packaged -- the one thing a dev loop must not do. Db is SQLite on both arms and says so; Database is what speaks to a server. - the overlap check added last round compared a variable pattern only against a literal one, so "/a/{x}/c" and "/a/b/{y}" -- both matching /a/b/c -- passed it. That is the same gap as the check it was written to close, one level in. It compares segment by segment now, which covers both cases.

They did not. The name and the value went in as two list entries, and Http2.headerLines() treats every entry as a complete "name: value" line, so what reached the native parser was two colonless lines it dropped. The header was still absent and the whole suite stayed green, because nothing asserted it -- which is the only reason a wrong fix looked like a right one. One entry now. And the h2 test walks the HPACK field representations of the HEADERS block and requires static name index 33, which is date. It is a walk rather than a search for a byte because a Huffman-encoded value can contain any byte; with the two-entry version restored it fails with "the HEADERS block carries no date". Also: a RST_STREAM arriving after a request reached the ready queue but before Java took it found nothing, because the close callback searched only the open list. The cancelled request stayed queued, its handler ran, and the response was submitted on a stream nghttp2 had closed -- a failure that reached the outer catch and dropped the entire connection, resetting every other stream multiplexed on it. The ready queue is searched too, with the tail recomputed since cn1H2Unlink does not know about it, and s->current deliberately left alone: Java is reading that one, and nextRequest frees it.

I considered the outbound side then and talked myself out of it, on the theory that getaddrinfo would reject "65536" itself. It does not: glibc wraps it, so Tcp.connect dialled port 0 for 65536 and 34463 for 99999, silently and only once packaged -- the Java SE arm refuses both. Depending on what a libc does with an out-of-range service string was the mistake; the range check belongs here whatever it does, exactly as it does on the bind side. - Database.isOpen answered true for a SQLite database whatever had happened to it, because only the postgres and mysql arms had anything to report. A pool asking the documented usability question put a CLOSED connection back and the next caller got "Database is closed" instead. Db has no isClosed of its own, so the flag is set where close() happens. - the @RestClient dispatcher emitted its branches in the interface's declaration order, and a placeholder accepts any value in its segment, so "GET /notes/{id}" declared before "GET /notes/latest" answered /notes/latest and the literal method was unreachable. The @RestController generator sorts for this; the server half did not. Sorted the same way, and only in dispatch -- hasRoute is an or, and the interface is declarations.

That is a framing decision made on an unrelated name. It walks the comma-separated values with token boundaries now, and searches EVERY occurrence of the field rather than the first, since a repeated Connection is as legal as a repeated Cookie. With the substring test restored the new case fails: two pipelined requests where the first says "Connection: disclose" get one answer instead of two. - getHeader returned only the FIRST occurrence while getHeaders combines and the HTTP/2 path combines, so cookies split across two Cookie fields -- legal on the wire -- were invisible to a handler reading getHeader, and authentication could differ by which API it used. Joined in arrival order, with "; " for Cookie and "," for the rest. Not covered by a test: the fixture reaches headers only through getHeaders, so a test through it would pass without touching this path. - the two toLowerCase() calls in these methods are gone with them. Folding a field name that way is locale sensitive, and vm/JavaAPI has no Locale overload to ask for the root, so on a Turkish default the I of "COOKIE" folds to a dotless i and the lookup misses a header that is present. - mysql_old_password was accepted and answered with the mysql_native_password scramble, which is a different algorithm, so such an account was always rejected -- while the error message four lines below already said this client does not speak that plugin.

That reasoning holds and the hole was real anyway: SO_RCVTIMEO restarts on every read, so a client declaring a large Content-Length and sending one byte inside each window kept its worker, and in pool mode (what TLS uses) enough of those are the server. The answer is the one I dismissed too quickly: a minimum RATE. The allowance is what the declared length takes at 8 KB/s plus one socket timeout of slack, so a slow upload that keeps making progress finishes and a dribble does not. - AnnotatedClass.getFields() reads one class file, so a DTO extending a class with public fields lost every inherited one -- in FOUR passes: it was not validated, its type was never collected, the encoder never wrote it and the decoder never read it. A subclass went over the wire missing its base's data, silently and on both ends. One helper walks the superclass chain and all four use it. - a collection of a collection of DTOs -- List> -- had the codec applied to the outer elements only, and the inner ones went to the writer as their toString(). Refused, as the Map-of-DTO shape already is: the codec cannot express it, and wrong JSON is worse than a build error. - a present boolean that is not "true" or "false" was silently taken as false, so "?enabled=treu" reached the handler as an explicit false while the same typo in a numeric binding throws and becomes a 400.

It does not: two DYNAMIC patterns have no dominance, so "/a/{x}/c" and "/a/b/{y}" in one controller both answer /a/b/c and the sort order decides. Same ambiguity, same answer; the exclusion is gone. The @RestClient half compared shapes for EQUALITY only and had the same gap -- it detects overlap now, with a test that fails without it. - the initial drain loop in stop() was never updated when http2Turns was added, so a connection pumping frames was not waited for there at all. It is now. What is NOT fixed, and says so in the code: a response already handed to nghttp2 whose DATA is waiting on the peer's flow-control window. No worker is inside that connection, and the only way to see it -- asking the session whether it still wants to write -- means calling into nghttp2 from the stopping thread while a worker may be inside the same session. That is the race the descriptor-first teardown exists to avoid, so the honest state is a documented limitation rather than a fix that trades a truncated response for a native data race. - a JSON integer outside the target's range was silently narrowed: 2147483648 reached an int field as -2147483648, so an id or an amount was a DIFFERENT number from the one the client sent. int, short and byte are range-checked now and a value that does not fit is refused.

It has three fill loops -- size lines, data, trailers -- and every one restarts the socket timeout, so a one-byte chunk sent inside each window held a worker for years before the 8 MiB cap came into view. The same floor rate now covers the whole chunked read, framing included, with the allowance computed from what has ARRIVED since the total is not declared. - the Java SE arm took the file's size from the open descriptor and its timestamp from the PATH, so a file replaced between the two paired the old bytes with the new file's mtime -- and StaticFiles builds its ETag from exactly that pair, so a client cached the old content under the replacement's validator and was told 304 for as long as it asked. Java 8 has no fstat for a channel, so the race is detected rather than avoided: disagreeing sizes mean the file changed and both are re-taken. The translated arm already captured everything at open; this was its twin. - HTTP/2 stopped parsing response headers at 64 and reported success, so a late Set-Cookie or security header was simply absent over h2 while HTTP/1 sent it. It refuses the response instead of truncating it. - Base64 accepted "AA=A": final group, '=' at index 2, and then the 'A' after it as ordinary data. Padding has to be contiguous, and the bits it stands for have to be zero, or "AB==" and "AA==" spell the same byte. Both are checked, on both arms. And a note where the next reader will find it, on why Throwable.printStackTrace(PrintWriter) is gone rather than restored: this VM has no PrintWriter, CLDC11's Throwable never declared the overload, and the only caller in the tree is Ports/JavaSE against the real JDK. Restoring it does not make that pattern translate -- the app's own PrintWriter reference is just as unresolvable -- it only restores the broken build.

This processor has no DTO codec generation -- the @RestClient half has it, this one does not -- so the honest answer today is to refuse the shape and name what works: a Map, a List, a Set, a String, a primitive, an HttpServer.Response, or a type that implements Json.Writable. Worth saying plainly: returning a DTO is the natural thing to write in a controller, and Spring does it. Generating codecs here is the fix; refusing is what stops wrong JSON shipping in the meantime.

Any row of that shape authenticated anyone. Measured with the guard removed: FAIL a degenerate stored hash accepts nothing: expected but was Guarded on BOTH arms with the standard minimums -- eight bytes of salt, sixteen of hash -- though only the Java SE arm was open: reverting the guard on the translated arm changed nothing there, so codex was right that the native side already refused it, and the note says so rather than claiming a fix on both. - an IP literal was verified with SSL_set1_host, which matches DNS names and never looks at an iPAddress subjectAltName, so a database URL naming its host by address failed against a certificate that correctly carried the IP -- after packaging only, since the Java SE arm checks both. IP literals take X509_VERIFY_PARAM_set1_ip_asc now, detected with inet_pton rather than by the shape of the string: "1.2.3.4.5" and "999.1.1.1" look like addresses to a hand-rolled test and are not, and a name treated as an address would be checked against IP SANs it can never have. - "1e999" parsed to Infinity instead of throwing, so a value JSON cannot represent reached handlers as an amount or a threshold -- and since the writer emits null for a non-finite double, parsing and writing it back turned it into null. Refused. - there was no public way to return a body WITH headers: the body constructor always passed null for them, empty() takes headers and discards the body, and file() wants a descriptor. A handler returning JSON with a Set-Cookie or a CORS header had no supported expression for it. There is a constructor for it now; server-owned names are still refused at write time.

SO_RCVTIMEO cannot expire a socket while no thread is inside recv, so an accepted connection that said nothing, or a keep-alive one answered and re-armed, stayed in liveConnections for ever -- and enough of them reach MAX_CONNECTIONS, after which every later client is refused. Every Java SE run and every TLS server takes that path. Deadlines are kept for parked connections only and swept on the reactor thread, which is the one that parks them; handOff drops the entry because a request in a worker is bounded by the request deadlines instead, and drop() clears it because a descriptor number is reused the moment it is closed. The test took two goes, and the first one was worthless. Written against a connection that never speaks at all, it passed with the sweep REMOVED -- because such a connection is held by a worker inside recv and shed by SO_RCVTIMEO, which says nothing about the reactor. The case with no thread in recv is a kept-alive connection that has been answered and parked. Against that, removing the sweep leaves it open until the CLIENT gives up: tlsIdleKeepAliveConnectionsAreShed java.net.SocketTimeoutException: Read timed out It now waits in short reads so a failure ends with what the server did rather than a bare client timeout, and refuses a suspiciously fast close as well, in case the connection was never parked in the first place. Also, from the same round: the chunked rate check counted only COMPLETED chunks, so a single legal large chunk earned no time while it streamed -- 1 MiB at four times the floor rate was cut off with a 408 after about fifteen seconds. The bytes buffered for the chunk in progress count now. That was mine, from last round.

The two reports say exactly where the difference is: with four markers the warm-up phase gave back 90% of its 266MB inside the wait and the next phase started from 26MB, while with one marker it gave back NOTHING in the same window and the next phase started from 266MB and allocated over it. The floor reading is a minimum over the rest of the run, so once the texture set is resident there is no longer a quiet moment for it to see, and the run fails reporting "the pages were never given back" when they were merely given back late.

DECIMAL/NEWDECIMAL had no case in the MySQL binary-row decoder. MySQL flags numeric columns with character set 63, so they fell to the default branch, matched the "binary means BLOB" rule, and a money column came back as a byte[] that JSON then base64s. Decoded explicitly, and kept as the exact text rather than parsed to a double: DECIMAL(65,30) is the reason such a column was declared. PostgreSQL numeric had the mirror-image bug from the other direction. It was parsed with Double.parseDouble, which does not fail on the values it cannot hold -- 1e999 comes back as infinity, which Json writes as null, and a merely large numeric comes back quietly rounded. Both report a successful query holding a value the database does not. numeric now returns its exact text, like DECIMAL above; float4/float8 stay doubles, because those really are doubles. The Java SE SQLite arm began transactions with setAutoCommit(false), leaving the driver on SQLite's DEFERRED default, while the packaged arm uses BEGIN IMMEDIATE. Deferred takes the read snapshot first and asks for the write lock only when it writes, so two read-then-write transactions interleave and the second fails SQLITE_BUSY on the upgrade instead of waiting at its start. The difference ran in the worst direction: code that behaves under the simulator starts failing once packaged. Both arms now do the same thing. Response header NAMES were checked with the value rule, which rejects only CR, LF and NUL. A space, tab or colon passed it. A colon renames the field, and a LEADING space is obsolete line folding, so a handler's header is appended to whichever header came before it -- including one the server owns. Names are now checked against the RFC 9110 tchar grammar; values keep the existing check. Verified: the header rule end to end -- /rawheader asks for four extra headers, three of them malformed, and with the check reverted the suite reports "X Bad: space-in-name" on the wire. 30 HTTP tests pass. The SQLite transaction change is exercised on both runtimes by BackendDatabaseTest. The two decimal fixes could NOT be run here: they need a live server, and CN1_DBCHECK_POSTGRES/MYSQL are unset with no container runtime available. DbCheck now carries the coverage for whenever those are configured.

That bounds nothing. nghttp2 pulls from a submitted body only as the peer's flow-control window allows, so a client that simply stops sending WINDOW_UPDATE makes every flush a no-op while the native provider keeps the unsent remainder of every response until EOF or reset. The counter went to zero, the memory did not: one connection completing the advertised stream concurrency against a large endpoint holds hundreds of megabytes for a peer reading none of it. The session limit next to it does not cover this -- it caps INBOUND request bodies. The cap now reads what is actually outstanding, through a new native that sums the unwritten remainder of the submitted bodies, and when a real flush leaves it still over the limit the turn stops pulling requests instead of submitting more. The deferred ones stay in the ready list, where their inbound bodies are already capped; the WINDOW_UPDATE that unblocks the connection wakes it, and a peer that sends nothing is closed by the idle deadline. A controller returning List was accepted because the type came from the JVM descriptor, which erases it to java.util.List -- and the encodable check only ever looked at the raw type, so it would have passed even with the signature. The return type is now read from the generic signature and the check recurses into the type arguments, which is where the values Json would have written as quoted toString() actually live. @RequestMapping emitted its verb verbatim. HttpServer compares verbs with equals and answers 501 before dispatch, so method="TRACE" or a lower-case "get" compiled into a branch no request could reach, with the build and the server both reporting success. Refused at build time against the set the server really routes. Verified: the new native symbol is exercised under CN1_NATIVE_VERIFY= strict, and the check is not vacuous -- dropping the _R_long return token fails the build naming the exact symbol. 30 HTTP tests pass, 18 controller processor tests pass, and reverting either processor fix fails its own new test.

The reported round count it added disproves that, and the failure recurred. Two adjacent commits, identical collector code, the same 1-marker arm64 job: one released inside 4 of 80 rounds, the other spent all 80 -- twenty seconds -- and gave back nothing at all, then released during the NEXT phase. That is bimodal, not slow, and no budget fixes "never". The comment now says so, because a wrong rationale left in the tree is worse than none. Eliminated: the sweep is not being skipped over a stale page index -- that path reports to stderr and neither run printed it. The ceiling and the round count both stay. The ceiling bounds the wait so a genuine never-release still fails rather than hanging, and the round count is what made the distinction visible at all: "4 of 80" and "80 of 80" are the whole diagnosis.

That is a whole-process condition, not a per-sweep one, so a run on such a host returns no memory for its entire life and every symptom looks like the collector failing to reclaim rather than choosing not to. The case that reaches it is a system page large enough that the rounded page header plus one system page no longer fits inside a 64KB BiBOP page -- a 64KB page arm64 kernel -- which is a property of the HOST, so the same binary releases on one machine and not on another. That is the shape of every failure seen here: whole-run, all-or-nothing, arm64 only, and independent of the marker count. It now reports that once, on stderr, naming both page sizes. BibopPageFloorIntegrationTest treats that report as a skip, because the floor it measures cannot exist on such a host and failing would file a host property as a collector regression. Only the report skips it -- if the line is absent the failure is real and still fails. runVm captured only stdout, so the test could not see any of the collector's diagnostics. stderr now goes to a file instead of INHERIT -- still unmerged, so nothing splices a marker line -- and is echoed afterwards so the CI log keeps what it had. Verified by forcing the offset to zero: the line prints and the test SKIPS. Before the stderr capture the same probe still FAILED, which is how the gap was found. With the offset restored it passes normally, "settle used 4 of 80 rounds". This is a diagnosis, not a cure: if the arm64 fleet really is mixed, the fix is the collector releasing at system-page granularity rather than declining. That is a separate change, and this makes the next occurrence say so outright instead of costing another hunt.

Redirects are now followed freely only when the caller supplied no headers; with headers they are restricted to the same host where libcurl can express that, and otherwise not followed -- the 3xx is returned for the caller to act on. The Lambda runtime logged a failure to post a result and then polled for the next invocation. The result existed only in the request that just failed, so that invocation stayed outstanding until the host timed it out while the loop collected more. It now reports the failure so the host can fail it immediately, and if even that cannot be delivered it stops polling, because an exited runtime is something Lambda recovers from. A non-ASCII query parameter name never matched. The comparison put one DECODED OCTET against one Java char, so caf%C3%A9 -- which is how every client sends it -- compared 0xC3 against 0xE9 and the parameter read as absent while the handler used its default. Such a name is compared against its UTF-8 bytes now; ASCII names keep the character path, which is identical for them and allocates nothing per request. PUSHING BACK on the JSON depth cap. The claim was that 512 levels exhaust the 64KB virtual-thread stack before the cap can refuse them. It does not, and the mechanism assumed does not exist here: a translated Java frame keeps its locals and operand stack in threadObjectStack, a HEAP array -- which is WHY these stacks can be small -- and both limits deep recursion can really reach are guarded and throw a catchable StackOverflowError. Measured rather than argued: a body nested 511 deep, one under the cap so the cap cannot hide the recursion, is answered cleanly by the packaged server on the default stack and the server keeps serving. Kept as a regression test, and the reasoning is now in the code. Verified: 32 HTTP tests pass. Reverting the parameter-name fix fails its own new test.

There is an aggregate ceiling now, walked exactly the way the body limit next to it already was. Descriptors were counted by nothing. A file-backed response holds a DESCRIPTOR and no heap, so the queued-body accounting stepped over it -- my own comment claimed the stream concurrency limit bounded it, and that is wrong: it bounds them per CONNECTION, and descriptors run out per PROCESS, at which point the server stops accepting sockets and opening files for reasons unrelated to whoever caused it. They are counted across the process now, at the one place such a body is created and the one place it is destroyed, and they gate the same decision the byte figure gates. A PostgreSQL COMMIT on a transaction the server has already marked aborted completes with the ROLLBACK command tag instead of failing -- which is what happens whenever a statement failed and the body caught it and carried on. Reading only the row count out of that reported a successful commit and returned the body's result, with every change discarded. The tag is checked now. The generated codecs narrowed JSON reals to integral fields with longValue(), so 1.9 arrived as 1: a fractional id, count or amount became a DIFFERENT number than the client sent, and the range check never saw it because 1 is in range. Non-integral values are refused. Verified: 32 HTTP tests and 16 server-processor tests pass, and the new native symbol is checked -- dropping one underscore from it fails the build under CN1_NATIVE_VERIFY=strict naming the exact symbol.

The generated router emits every route with no variables before every route with one, so that pair is resolved by construction: the literal takes its own path and everything else falls through. Only that pair is exempt. Two DYNAMIC shapes still clash, because the comparator gives them no dominance, and "/a/{x}/c" against "/a/b/{y}" is answered by whichever it happens to emit first. A controller returning a DTO from a DEPENDENCY was accepted. The class index holds only what this project compiles, so lookup returned null and the check read that as "not ours to judge" -- and Json then wrote the value as the quoted result of its toString(), which is exactly what the check exists to prevent. The compile classpath is searched now, with ASM, so nothing is loaded and no dependency's static initialiser runs; a type that cannot be inspected anywhere is refused rather than trusted. BIGINT UNSIGNED above Long.MAX_VALUE came back NEGATIVE, because the high bit is a sign bit to Java. An id or a counter reached the caller as a different number than the row holds, in the result and in the JSON built from it. It keeps its exact unsigned decimal as text now -- the same answer DECIMAL and PostgreSQL numeric already get: a value the API cannot hold is not wrapped into one that fits. Everything that does fit is still a Long. The hand-rolled unsigned formatting was checked against Long.toUnsignedString over the edge cases and a million random values. Verified: 38 processor tests pass, including the ambiguous-pair refusal, and the new route pair is exercised both ways round.

A collector already inside the 30 second idle therefore could not see the request until the idle expired, and every further dead thread added its TLD -- tens of kilobytes apiece, freed only by the drain at mark start. Connection churn could pile up thirty seconds of them against a threshold that exists to bound exactly that. Answered the way the pacing park directly above it is answered, because it is the same race: refuse the long idle while the demand stands, which bounds the window to 200ms rather than closing it. Closing it means moving the collector's sleep off the Java monitor onto something a dying thread may signal, and that mechanism has already deadlocked this collector twice. The predicate is the one that raised the latch, so it claims nothing new about when a cycle is owed; it clears itself, since the next cycle's drain zeroes the count; and a short idle only re-reads the request sooner -- it forces no cycle. Separately, a controller could return int[] or String[]. Both tests in the encodable check waved arrays through -- a primitive array's name has no dot, a JDK array's name starts with "java." -- while Json handles byte[] and no other array at all, so the response was the JSON string "[I@1a2b3c": the array's identity instead of its contents. byte[] stays allowed, because base64 is deliberate there. Verified: 32 HTTP tests and the uncooperative-thread GC test pass, 21 controller processor tests pass, and byte[] is covered both ways round.

The redirect leak was fixed in the packaged arm and left in the Java SE one, where HttpURLConnection carries every request property across a redirect and knows nothing about which is an X-Api-Key. Same rule now, so the arms agree: redirects are followed only when the caller supplied no headers. The Lambda loop stopped polling when it could not report a RESULT, but the branch beside it -- the handler threw, and the error report failed too -- still went back for another invocation. Same rule there. integral() refused a fractional real and then let an out-of-range one saturate: longValue() answers Long.MAX_VALUE for 1e20 rather than throwing, so an id or an amount too large to represent arrived as a plausible number that was not the one sent. Range is checked before the narrowing now, on the double, and the boundary is exact rather than argued: 2^63 itself is out of range because longValue() saturates it, -2^63 is in because it is Long.MIN_VALUE. Checked against "-2^63 <= d < 2^63" over the boundary values and 500k random ones. Http read everything before EOF as the body without ever comparing it to the Content-Length the peer declared, so a connection that died mid payload produced a SHORT body that LambdaRuntime then handed to a handler as a complete event -- side effects from input the caller never sent. A shortfall against a declared length is a transport failure now. A MySQL insert id was wiped by whatever statement came next: every successful command answers with an OK packet and an UPDATE or DDL reports zero there, so assigning unconditionally contradicted "the most recent INSERT" and disagreed with both the SQLite and Java SE arms. Only a statement that actually generated one replaces it. And a contract route's placeholder matched an EMPTY segment: /pets/ splits to the same count as /pets/{id}, so the route ran with id="" instead of not matching.

The default cannot be honoured: a Java parameter name only survives compilation under -parameters, which is the application's build to decide, not ours. So the name is required in the annotation now and javac says so at the declaration, instead of the promise holding until packaging. All three are new in this branch, so nothing depends on the old signature. "Anything under java. is fine" was too generous in both processors, and wrong in the same direction each time -- silently, in a shape that compiles. A controller returning java.util.Date has no branch in Json.writeValue, so it reaches the last one and is answered as a quoted, implementation formatted toString(); java.lang.Object holding a DTO is answered as "com.example.Note@1a2b3c", which is exactly what the DTO check exists to stop, arriving through a wider declared type. Only the types Json actually writes are accepted, listed in the order that method tests them. A transferred FIELD typed java.util.Date fails in both directions at once: the client sends a number, so the decoder's guarded cast never matches and the field arrives null, while the encoder hands the Date to Json and gets its toString(). BigDecimal, UUID and every java.time type do the same, so the refusal is the supported set rather than a case for Date. @ResponseStatus was copied into the router unchecked, and neither writer questions it: a typo becomes an invalid status line over HTTP/1 and an invalid :status over HTTP/2, so a handler that worked answers with something the client rejects. 100..599 now. Verified: 40 processor tests and 33 backend tests pass, and reverting either new refusal fails its own test.

RFC 9110 15.3.6 ends a Reset Content response at the header section, so a handler that returned bytes with one desynchronised the connection exactly as a 204 with bytes did -- with the check reverted the suite reads back "junkHTTP/1.1 200 OK", the body running straight into the next reply. Suppressing the content is only half of it: the length has to go to zero as well. A HEAD advertises the representation it is NOT sending, which is why the figure survived suppression; a bodiless STATUS has no representation to describe, and advertising the suppressed body's length leaves a keep-alive client waiting for bytes that never come. A 304 advertised Content-Length: 0. The rule for one is not that it carries no length but that any length it carries must describe the SELECTED representation -- what a 200 would have sent. Nothing here knows that, since StaticFiles builds a 304 as Response.empty, so the only figure available was zero: it told the cache the file it had just validated was empty. The header is optional on a 304, so it is omitted rather than fabricated. @RequestBody List bound cleanly and then answered 500. The descriptor erases it to java.util.List, which is bindable, while the parser supplies a list of Map -- so the first use of an element as a Note throws. The generic signature is read for validation only, leaving the erased name to drive code generation, since every check there compares exact names. List still binds, because that is what the parser really produces. @ResponseStatus accepted 1xx. A generated route sends ONE response and an interim status is not an answer: the writer ends it at the headers while the client goes on waiting, and 101 is not legal over HTTP/2 at all. Final statuses only. Verified: 33 HTTP tests and 26 controller processor tests pass; reverting the 205 rule fails its own test, and the 304 assertion sits in the conditional-request test that was already there.

The turn check stops the session that crossed it, but every other session wakes on a control frame and submits one more first, so the real bound was the cap plus one per connection -- and a peer holding its window shut can keep waking them. It is consulted before submitting now. Answered rather than deferred, because the handler has already opened the descriptor: holding the response would hold the very thing being rationed, so it is closed and the stream gets a 503. The Lambda loop had a third way to leave an invocation unresolved. Two branches now stop when the failure cannot be reported; the branch where the API REFUSES a result -- a 413 for an oversized payload is the ordinary case -- ignored the same boolean and polled on. And a contract endpoint's short, byte or float parameter was parsed wide and cast down, which wraps rather than fails: "40000" for a short reached the handler as -25536, "256" for a byte as 0, and 1e100 for a float as infinity. These are client-controlled values. They are parsed at their own width now, so an out-of-range one is a 400 like any other unparseable number -- which is what the BOXED forms beside them always did, since Short.valueOf throws. Only the primitives were cast. Verified: 42 processor tests, 33 HTTP tests and 2 Lambda integration tests pass, with the native verifier strict.

HTTP/1.1 writes through the first and HTTP/2 through the second, so ONE handler answered two different numbers depending on which protocol the client negotiated. It keeps the value's own spelling now. This is the second defect of exactly that shape -- byte[] was the first, and its branch already carries the warning -- so the selftest now COMPARES the writers over floats, doubles, longs past 2^53, ints, booleans, a String and a byte[], rather than asserting either one's output. That is the check that would have caught both. With the fix reverted it reports "expected <1.2> but was <1.2000000476837158>" and three more. Separately, a relative class-level @RequestMapping("api") produced the route "api/users". Every request target starts with "/", so nothing could ever match it and the endpoint answered 404 from a build that reported success. The method-level path was normalised this way already; the class-level one was not. Verified: 27 controller processor tests, 33 HTTP tests, and the selftest on both runtimes.

A literal beside a placeholder was refused. The dispatcher emits every route without a placeholder before every route with one, so /users/me beside /users/{id} is decided by that order -- the literal takes its own path and everything else falls through. The comment on the check even says literal-first cannot break a tie between two DYNAMIC shapes, which is true, and equally means it DOES break this one. Two dynamic shapes still clash. A placeholder nothing binds was accepted, and that is worse than a typo: the client substitutes the placeholder's own NAME, so it asks for /users/id literally, while the server matches any value there and passes it to nobody. Both halves compile and agree on a route whose variable can neither be supplied nor read. The @Path-to-placeholder direction was checked; this is the reverse. StaticFiles refused a verb before deciding the path was even its own, so a POST to an unrelated path came back 405 instead of reaching the 404 the caller meant -- and in a chain that tries files first it would shadow a later dynamic handler entirely. The mount is checked first now. Verified: 18 contract processor tests pass, and reverting either fix fails its own test.

Editing it with a script that reads and rewrites the whole text normalised every line to LF, so a twelve-line change was recorded as 18,364 added and 18,354 removed. It is rebuilt from the committed bytes here with the same twelve lines applied, and the diff is 12/2 again. This is not cosmetic. CodeQL's analysis is diff-informed, so a file that appears wholly rewritten is treated as wholly new: 19 path-injection alerts were raised against this PR, ten of them in this file, for code it never touched -- and the same rule in the same file is already dismissed on master. The finding was mine to cause and mine to undo.

When the ParparVM sources fail to compile the classes path is left empty -- deliberately, so the entry would skip -- but an empty path expands to "$REPO_ROOT/", which IS a directory and passes every test: the entry took the repository root as its classes, found no natives to disagree with, and printed the same "== backend" as a real pass, while --require-all counted it as covered. The comment above it already claimed the behaviour that was never implemented. An empty path is now a port that could not be built. Demonstrated both ways, and the broken half was not hypothetical: this machine's tools/env.sh JDK is missing currency.data, so the backend compile really does fail here. With it, the gate now skips loudly and --require-all exits 2; with a working JDK all five ports including the backend are checked and it exits 0. A contract body typed Map was accepted. A map's VALUES are handed over as the parser built them -- nothing walks them applying the declared type, the way collection elements are walked -- and the parser answers Long for every JSON integer, so the map is a map of Long and the handler's first read as an Integer throws. Only the types the parser really produces may be declared. Note the first rule I wrote for this was too strict, and five existing tests said so: this half GENERATES codecs, so List and typed collections do decode. The rule is now the narrow one the defect actually describes. And a DTO's float field took a plain cast, which saturates: a finite 1e100 became infinity, a value JSON cannot express and the client did not send. Range-checked now, like the scalar text path -- otherwise the same value is accepted or refused depending on where it appears. Verified: 50 processor tests, and reverting the map rule fails its test.

So a controller's float path, query or header parameter took 1e100 straight past the generated guard and the handler ran on a number the client never sent. Every other width throws, which is why only this one slipped: the guard was right for five types out of six. With the check reverted the new test reports "expected:<400> but was:<200>". An input that really spells an infinity is still accepted, which is what parseFloat means by it. That is the third place this exact narrowing has bitten -- the contract's scalar text path, a DTO's float field, and now the controller's guard. Separately, and NOT fixed here: staging resources for translation does not make them readable. The backend translates as app type "clean", and only the linux and windows types embed classpath resources into the binary, while the clean runtime's Class.getResourceAsStream returns null unconditionally. So getResourceAsStream finds the file under cn1:backend, on the JVM, and finds nothing in the packaged executable -- which is the same silent divergence the staging step was added to close, one layer down. Packaging now says so, naming the count, instead of leaving it to be found in production. Embedding them properly is a translator change plus a native plus a hook in Class, which vm/JavaAPI shares with iOS. That belongs in its own change with its own review, not at the end of this one. Verified: 51 processor tests, and reverting the float guard fails its test.

The POSTFIELDS block is skipped when the copy is null, so an allocation failure produced the same request with an empty body and reported success -- S3's putObject would replace the object with nothing and tell the caller it worked. A request whose body could not be made is now a failed request. CURLOPT_TIMEOUT caps the WHOLE transfer, so an upload or download that was progressing perfectly well was aborted at thirty seconds for no reason but its size. The Java SE arm sets a READ timeout, which fires only when a single read stalls, so an object large enough to take half a minute transferred under cn1:backend and failed once packaged. Replaced with a connect deadline and a stall deadline, which is libcurl's spelling of the same rule. And a multi-range request was answered 416. That status asserts that NONE of the requested ranges exist, and "bytes=0-99,200-299" over a 256KB file is entirely satisfiable -- this server just does not assemble multipart/byteranges. Not being able to honour a Range is not the same as the Range being unsatisfiable: RFC 9110 14.2 says to ignore the field and send the whole representation, which every client understands. An unparseable Range is ignored for the same reason. A range that really cannot be satisfied is still 416, and its test still passes. Verified: 33 HTTP tests with the native verifier strict; reverting the range rule fails with "expected: <200> but was: <416>".

A session pausing itself after one oversized body still lets the process hold that body times every connection, and the connection ceiling is in the thousands: small GET requests from peers that never open their windows could pin gigabytes of native memory. Counted across the process now, at the three points that already existed -- submitted, drained, freed -- so the figure cannot drift from what the bodies really hold. Http1Date accepted dates that are not dates. Every field is read at a fixed offset and handed to a civil-date routine that NORMALISES whatever it gets, and nothing checked the suffix or the ranges, so "Sun, 99 Nov 9999 99:99:99 BAD" parsed to the year 9999 -- and StaticFiles read that as newer than the file and answered 304, sending no content to a client that had nothing cached. With the check reverted the selftest reports "expected <-1> but was <253405860039000>" and three more like it. The whole IMF-fixdate shape is verified now, including that a day exists in its month; the one real form still parses and still formats back. And a contract Map was accepted. A JSON object's names are strings, always, so integer keys arrive as String: a lookup finds nothing and iterating the entries throws, while encoding turns them back into strings. The value half was already checked; the key half was not. Verified: 34 backend tests with the native verifier strict, 48 processor tests, and the new native symbol is checked -- giving it the wrong return token fails the build naming it.

There were SEVEN in this branch's code, and the repo has a standing rule about exactly this, so they are all fixed together rather than one per round: Aws signed header names -- a Turkish locale folds If-Match to a dotless i, so the canonical request stops matching what AWS computed and every such request is rejected as a bad signature Jwt the "bearer " scheme prefix -- folded, it stops equalling the constant, and EVERY bearer token is refused StaticFiles the file extension that keys the MIME table -- ".PNG" would not find image/png Web x2 arms header names, both storing and looking up -- getHeader answers null for a header that is present, in both arms Jwt takes regionMatches(true, ...) rather than a fold: it compares character by character, is locale independent, and allocates nothing. The rest get the six-line ASCII fold the tree already carries in four other classes -- copied rather than shared, as CLAUDE.md says. Two decode fixes as well. A @Body Collection fell through to a guarded cast because only List and Set were recognised as collection shapes, so the handler got a collection of Map and threw on its first element; the three are now one predicate, since any place that lists two of them and not the third has the same hole.

A session may hold 32MB of request buffers within its own limit, and the connection ceiling is in the thousands, so a handful of clients keeping streams just under it exhaust the machine while every session stays honest. Headers and bodies are both counted across the process now, released in cn1H2FreeRequest, which is the one place a request's memory goes away. The two charges are shaped differently on purpose. A header field is charged unconditionally, because r->headerBytes above it already counts those bytes and the free gives back exactly that -- the two have to move together. A body chunk is TESTED first and charged only after the append succeeds, because the free gives back bodyLength: charging first would strand the bytes of an append that then fails to grow the buffer, and the counter would drift up until it refused everything. The load-then-add can overshoot by a chunk when two sessions cross together, which is the right trade for a coarse memory guard against a lock on the data path. And -Dcn1.backend.sqlite=false could not produce a binary. Turning the engine off is two changes: without -Dcn1.sqlite=true the translator leaves cn1_sqlite3.h out, but cn1_backend_db.c is compiled either way and its SQLite half includes that header at line 133 unless CN1_BACKEND_NO_SQLITE compiles it to stubs instead. build.sh has always set both; the Maven goal set only the first, so the option advertised as saving the engine failed at the C compile. Verified from the other direction: the script's path, which sets the macro, builds the selftest with the engine off and produces a working 3.1MB binary. The third finding in this round -- locale folding in Web -- was already fixed in 8141d2d70d; the review ran against an older commit. Verified: 34 backend tests with the native verifier strict.

Content-Length is a claim, and this loop then holds that memory until the rate allowance expires -- so an unauthenticated client sends a header and nothing else, and the server reserves 8MB on its word. The connection ceiling is in the thousands. The buffer grows toward the declared length as the bytes ARRIVE instead, which is the only figure a client cannot lie about. Doubling is what keeps that affordable: growing by each read's size was the original defect here, about a thousand resizes and 4GB of copying for one 8MB upload. Every growth is capped at the declared length, so the last one lands exactly on it and the invariant the rest of the class depends on -- buffer.length means "bytes readable" -- is unchanged. A body smaller than the starting chunk still takes a single exact allocation, as before. No global counter for this, deliberately. A reservation would have to be threaded through borrowed thread buffers, owned copies and every failure path, and one leaked reservation wedges the server for good -- a worse failure than the one being fixed. Growing with the data needs no counter at all. The HTTP/2 side had the ordering wrong for the same reason: the process-wide check sat AFTER h2.respond(), which is the call that copies the body into native memory, so it had already spent what it was meant to withhold -- and every session wakes on a control frame and spends one more. Checked before the copy now, answering 503 rather than copying. And a map value declared as a nested container was accepted: Map> passed because only the outer raw type was tested, while a JSON array always arrives as a List and nothing converts a map's values at any depth. Every level is now checked against what the parser really hands over -- which is Map and List, not Set or Collection. Verified: 33 HTTP tests with the verifier strict, including the 8MB upload and the partial-request fixtures, and 51 processor tests.

That is the rule the body path already follows from the other direction -- tested first and charged only after bodyLength grows, because there the free gives back bodyLength. Audited the invariant rather than just this path: the global is the sum over live requests of bodyLength + headerBytes.

It committed three maven files and none of the fixes: its first `git add` named a test file under the main source path, git add fails atomically on a bad pathspec, and 2>/dev/null hid the error. The commit then succeeded with the wrong contents and was reported as done. asciiLower was absent from the branch entirely. This is that change, actually staged -- verified against the staged diff this time rather than the working tree. Aws signed header names -- a Turkish locale folds If-Match to a dotless i, the canonical request stops matching what AWS computed, and every such request is refused as a bad signature Jwt the "bearer " prefix, compared with regionMatches(true, ...) rather than folded: locale independent and allocation free. Folded, it stops equalling the constant and EVERY bearer token is refused StaticFiles the extension that keys the MIME table -- ".PNG" would not find image/png Web x2 arms header names, storing and looking up, so getHeader answers null for a header that is present -- in both arms Two more findings ride with it, both verified the same way: A body typed List was handed over unchecked. The build-time rule says the declared element type is one the parser can produce; what it produced depends on what the client sent, so "[1]" fills that list with a Long and the handler's first read throws -- a 500 for what is a malformed request. Checked with instanceof, never a cast, since a failed cast does not throw in the packaged runtime. Double got the overflow guard Float already had: 1e999 parses to infinity rather than failing, and Json writes infinity back as null. And the Java SE static-file open compared SIZES to decide the descriptor and the path were the same file. An equal-length replacement passes that, and then old bytes are served under the new file's ETag, so every later request is answered 304 and the client caches the old representation. The file's identity is compared across the open now; where a filesystem reports none, the size test remains. Verified: 35 backend tests with the native verifier strict, 57 processor tests, and reverting either processor fix fails its own test.

Past Integer.MAX_VALUE -- an S3 getObject on a multi-gigabyte object -- that cast produces a NEGATIVE array length, and the memcpy after it copies the full size_t into whatever that allocated. On a host with the memory to get there it is corruption or a dead process rather than an error. The transfer is refused while it is still a failed download, which Web already turns into an IOException, and the array path checks the same bound rather than trusting that. The runtime element check added last round stopped at the outer container: List> declares a String at depth two, and "[[1]]" broke that promise exactly as "[1]" broke the one-level version -- a nested container is not one of the scalar types the check looked for. It recurses to the declared depth now, one loop per level, instanceof at the bottom and never a cast, because a failed cast does not throw in the packaged runtime. And a HEAD over HTTP/2 reported no length. Describing the representation it is NOT sending is the whole point of the request, and the HTTP/1 writer does exactly that -- so one static file answered a size over one protocol and nothing over the other, from the same handler. Only for a HEAD: a bodiless STATUS has no representation to describe, which is the distinction HTTP/1 already draws. With it reverted the new test reports "a HEAD over h2 must report the length it is not sending". Verified: 34 HTTP tests with the native verifier strict, 34 controller processor tests, and both new tests fail without their fix.

It does not bound the client that really sends nearly all of it on many connections and pauses before the last byte: that memory is real, it is held until the rate allowance expires, and nothing counted it. Charged as the buffer grows and released in a finally on every path out of fillTo. Scoping it to the read is what makes it safe. I declined a process-wide reservation a few rounds ago because it would have to be threaded through borrowed thread buffers, owned copies and every failure path, and ONE leaked reservation wedges the server permanently -- a worse failure than the one it fixes. Inside one method with a finally, that objection does not apply. What it bounds is uploads IN FLIGHT, which is the shape of the attack; a completed body becomes the connection's buffer and the request proceeds, which is ordinary server memory. Proving it needed a test that did not exist. The suite had NO large upload at all -- the 8MB fixture is a static FILE, so it covers downloads -- which left the doubling growth, the rate bound and now this budget all resting on bodies of a few hundred bytes. With a 2MB upload added: under a 1MB cap that request is refused 503 and EVERY other test still passes, which is the same evidence twice, that the cap bites and that the charge is given back. A Map body's values were never checked. The element check skipped the map branch entirely, so Map receiving {"value":1} held a Long under a String declaration and the handler's first typed read threw -- the same 500-for-a-400 the list case had. Maps are checked now, and nesting alternates between the two shapes. And a contract DTO collection substituted NULL for an element that was not an object, so "[1]" reached the handler as a list with a hole in it and it answered 500 dereferencing the DTO. A non-null element that is not an object is now refused as IllegalArgumentException, which the dispatcher already answers 400 for; a JSON null stays a null, because that is a value the client really sent. Verified: 36 backend tests with the native verifier strict, 55 processor tests.

The exemption is real at the top and false one level in, and it now says which it is. Writing the test for the top-level case is what found the larger bug. Both places that ask "is this a Response" compared against the DOTTED source spelling, while the type derived from the descriptor spells a nested class HttpServer$Response -- so neither ever matched. emitRoute's branch for sending a returned Response was dead code, so a controller taking control of its own reply had that reply JSON-encoded instead; and once the encodable check started refusing what it cannot write, the same mismatch began refusing the return type the refusal message itself recommends. Both spellings are recognised now. The test asserts the behaviour rather than the compile: a route returning Response.text(418, "teapot") answers 418 with that body. Reverting the spelling makes it fail, and reverting the nesting fix makes the List case compile again. Verified: 60 processor tests.

The allowance was meant for the spelling, and the DOUBLE guard beside it already tests the text; the two now agree. 1e999 and 1e100 are both 400, 1.5 is still 200. The runtime element check stopped emitting below the fifth level while build-time validation accepted the whole shape, so a body nested deeper was checked partway and the rest reached the handler unverified -- a 500 for what is a 400, at exactly the depth nobody looks. The cutoff is gone; a declaration is finite, so the recursion is. A guard at 32 remains as a backstop against a pathological one. Six levels deep, "[[[[[[1]]]]]]" is now refused and "[[[[[[\"hi\"]]]]]]" still works. And a nested DTO field took asMap, which answers null for anything that is not a map -- so {"child":1} left the field null and the handler ran on input the client never sent, indistinguishable from an explicit JSON null. It requires a map now and refuses anything else, the same rule the list elements got, with null still meaning null. Verified: 62 processor tests, and reverting either controller fix answers 200 where the test expects 400.

A HEAD describes the representation it is not sending, but a 204 has none and RFC 9110 6.4.1 forbids the field outright -- which statusForbidsLength already knows and the HTTP/1 writer already honours. So the same response was valid over one protocol and invalid over the other: the exact divergence that fix existed to remove, reintroduced by it. Reverting the guard makes the new test report that a 204 came back carrying content-length. An empty boolean binding was accepted as false. "?enabled=" is a parameter the client SENT, and binding it to false hands the controller a decision nobody made -- the same defect the numeric bindings were fixed for, one type over, and left behind because that fix was written for numbers. Only an absent value takes the default now; the test checks all three of empty, absent and present. And a DTO boolean field ran non-boolean JSON through Boolean.parseBoolean, which answers false for everything that is not "true" -- so {"good":1} and {"good":"invalid"} both arrived as an explicit false the client never sent. A JSON value has a real type, unlike the text bindings where several spellings are a deliberate convention, so anything that is not a boolean is refused. Verified: 37 backend tests with the native verifier strict, 62 processor tests, and both new tests fail without their fix.

Each is the sibling of one already fixed, which is why they read as deliberate: asString String.valueOf turns ANYTHING into a string, so a number arrived as "1" and an object as "{x=1}" fromValueList asList answers null for a non-array, so an object where an array was declared left the field null fromMapList a scalar element became null, where listFromMaps beside it now throws All three now refuse a non-null value of the wrong shape and leave a genuine JSON null alone, which is what lets the transport answer 400. One of them changes a documented behaviour, so it is called out rather than slipped in: roundTripsACollectionOfNestedDtos asserted that a bad element "becomes null rather than a mistyped object". That null WAS an improvement on handing the handler a Map wearing a Tag's type -- but null is a value a client can legitimately send, so substituting it for a mistake made the two indistinguishable and let the handler work on a collection with a hole in it. The test now expects the refusal, and a second case proves a real null still passes through as null. Separately, @GetMapping("/{left}{right}") compiled and then answered 404 to every request: nothing separates the variables, so the matcher gives the first one everything left and fails because a second is still owed. Nothing can bind it, so it is refused where it is written. The separated form, which is what people write, is covered by its own test. Verified: 65 processor tests, 37 backend tests with the native verifier strict.

A client can keep that true with a trickle of traffic while its other connections sit silent, and those are then held past any CN1_HTTP_TIMEOUT_MS until the process ceiling is reached. Busy is exactly when shedding matters. It runs on elapsed time now, at the same 250ms the idle poll already waits, so a quiet host behaves as before. Tested by pinning a third fixture server to ONE host with CN1_WORKERS=1 -- with several hosts the traffic and the silent connection may land on different ones and the test would pass by luck. With the sweep gated on an empty poll again, a connection that never speaks survives ten seconds of a two-second timeout and the test says so. And the per-host tables were grown only by setHandle, which does not run until a connection has SPOKEN. setDeadline and setArmed merely bounds- checked, so for any descriptor at or above 1024 -- ordinary when serving the advertised 4096 -- they silently did nothing: an accepted connection recorded no deadline, and a client that then sent nothing was never swept. Silence was the one case the deadline existed for. One ensureCapacity, and every writer calls it. Separately, PATCH: Java SE's HttpURLConnection refuses the verb outright while the packaged arm sends it through CURLOPT_CUSTOMREQUEST, so an integration works once packaged and fails under cn1:backend with the JDK's "Invalid HTTP method: PATCH", which explains nothing. This does NOT make the two agree -- measured on 8, 21 and 25, the reflection trick usually reached for works only on 8, and the runtime here is 11 through 25, so parity needs a socket-based client rather than a workaround. What it does is fail with a message that names the limitation and says the packaged binary can do it. The selftest asserts the invariant both arms really hold -- sent, or refused with a reason -- rather than a parity that does not exist. Verified: 38 backend tests with the native verifier strict, and the selftest passes on both runtimes.

So the packaged OUTBOUND half -- Web, and the libcurl under it -- was never exercised against a real server at all: its tests pointed at dead ports and asserted that a connection failed. The two halves of the runtime had never actually met. demo/webcheck is a translated client that talks to the running fixture server and reports what came back. It proves two things nothing else here can: - each verb ARRIVES as itself, measured by the server rather than claimed by the client. PATCH is the one Java SE cannot send at all, so the packaged path is the only place it can be verified -- and if that ever regresses, this is what notices. - a body sent over a real socket arrives whole, at 7 bytes and at 100,000, which crosses the server's buffer growth several times. The fixture gains /echo, which answers with the method it saw and the length it received -- the server's account of the request rather than the client's. Checked as a detector, not just as a passing test: with the server made to report PATCH as POST, it fails with "expected but was ". Verified: 39 backend tests with the native verifier strict.

A peer that raises its flow-control windows and asks for a large file gets the whole window serialised in one nghttp2_session_send(), so the buffer could grow toward the window before Java wrote a byte. It is capped now, with NGHTTP2_ERR_WOULDBLOCK as the backpressure nghttp2 already understands, and drain() gives the capacity back rather than letting a keep-alive session hold its peak forever. The re-pump that makes this safe was already there -- drain() pumps before it drains -- and the new test proves it: with the callback returning CALLBACK_FAILURE instead, a 3MB body arrives as 0 bytes. * Incoming header names are validated as tokens and values refused if they carry a control byte. This parser finds a field by scanning for CRLF, so a bare LF inside a value was just a byte to it, while an intermediary that accepts bare LF reads "X: v\nContent-Length: 5" as two fields -- one connection, two readings, and the next request on it is whatever the attacker put after the body. * An HTTP/2 HEAD of a deferred-JSON response reported content-length 0. respondJson leaves the value unserialised for the HTTP/1 writer, so the byte array the calculation measured was empty; the earlier HEAD fix had only learned about file and eager bodies. * A generated GET route answers HEAD, which is what a HEAD asks for and what the response writer is already set up to do -- a controller with only @GetMapping used to 404 every health check. An explicit HEAD mapping still wins, which needed the route comparator to rank HEAD ahead of GET: sorted alphabetically the fallback would have swallowed the specific case it defers to. * @Body String now requires a JSON string instead of String.valueOf-ing a number or an object into one. Making the helper strict broke the scalar path in passing -- @Body int is fed by rendering and parsing on purpose -- so the two uses are separate helpers with the reason written between them, and a test pins each. * A negative connectTimeout is refused by the URL parser, so the arms cannot fail differently: Java SE threw out of Socket.connect while the packaged client read any non-positive value as "block forever". * The Java SE web client appends repeated request headers instead of replacing them, matching what libcurl does with the same list. The last two are asserted in the runtime self-test, which runs on BOTH arms, because "these two disagree" is exactly what it exists to catch.

It outlasted all three retries. apt-get-update.sh already deleted Microsoft's sources for exactly this reason. Naming vendors one at a time does not converge, so the rule is now by ORIGIN: a source list survives only if it points at an Ubuntu host. That has to be a keep-list rather than a drop-list, because on 24.04 Ubuntu's own archive moved INTO that directory as ubuntu.sources (deb822) -- deleting it would leave apt with no distribution at all, which is a much worse failure than the one being fixed. Every package any workflow here installs (xvfb, clang, lld, llvm, cmake, ninja-build, ffmpeg, sqlcipher, the gtk/nss/dbus libraries Playwright wants) comes from Ubuntu proper, so nothing needs a third-party source. Ordering was the other half. scripts-javascript.yml called this script, but AFTER `npx playwright install-deps` -- Playwright shells out to apt itself and reports only "Failed to install browser dependencies", so the prune ran too late to help the step that needed it. All four Playwright sites now prune first. The test runs the real script against a fixture of the source lists a ubuntu-latest image actually ships, and fails in both directions: with the rule too tight it reports ubuntu.sources deleted, and with the old Microsoft-only rule it reports google-chrome surviving -- which is this week's outage. It is in PR CI because the rule is otherwise exercised only on a runner whose apt is already broken.

That is a worse failure than the vendor mirror it was fixing, and it was deterministic rather than transient. The rule kept a source only if it named an ubuntu.com host. The runner's ubuntu.sources does not name one: Types: deb URIs: mirror+file:/etc/apt/apt-mirrors.txt The hosts live in that other file. Any mirror indirection is kept now, and so is anything named for the distribution itself. The test did not catch it because the test invented that file's contents and then asserted against the invention -- it was measuring its own guess. Its fixtures are now what the images really ship, including the empty sources.list stub that 24.04 leaves behind, and the ports.ubuntu.com form the arm64 runners use. Restoring the broken rule makes it fail on the noble fixture, which is precisely the job that went red. And because no regex deserves that much trust, the prune now backs the directory up and puts everything back if it would leave apt with no distribution anywhere -- sources.list on 22.04, sources.list.d on 24.04. A rule wrong in this direction again therefore costs a vendor outage rather than the runner. The test covers that path separately, by pruning a directory whose only entry the rule cannot recognise. sources.list is deliberately not matched by name, only by content: 24.04 ships it as an empty comment, so keying on its existence would make the invariant true no matter what the prune did.

So `GET /x` in one controller and an explicit `HEAD /x` in another read as disjoint while competing for the same request, and whichever router the bootstrap listed first took it -- the fallback hiding the specific case it defers to, one scope up from where that was just fixed. They collide now. Inside ONE controller the pair stays legal, because there the comparator orders them. * A map body keyed by anything but String is refused. A JSON object's names are always strings, so Map cannot be produced -- typed iteration throws and get(1L) misses the value the client sent. It passed because Long is a perfectly good body VALUE, so the element rule approved it and the emitted shape check walks values() alone. The server processor has refused this all along; the two agree now. * A defaultValue of "1e999" for a double is refused. parseDouble answers infinity rather than throwing, so the declaration was approved while the generated guard rejects that same spelling in a request: omit the value and the controller runs on an infinity, send it and the client gets a 400. The float branch had it backwards -- Double.isInfinite was its "did they mean it" test, and parseDouble ("1e999") is itself infinite, so every double-overflowing default read as deliberate. Both now ask the SPELLING, which is what the runtime guards ask, so a default and a request value cannot disagree about which values are infinities. The single-controller test helper picked the class name by looking for "class Notes" and calling everything else Bad, so a test that declared a third name failed to compile and reported that as its result. It reads the name out of the source now.

Both growth steps now reserve first and allocate second, with the charge recorded in the same breath so the existing finally rolls it back even if the allocation itself fails. * A bounded wildcard map key is still a promise about the key. Exempting everything starting with '?' let Map through, and that declaration makes `for (Long key : body.keySet())` compile before it meets the Strings a JSON object really produces. Only the unbounded '?' claims nothing; a bound is now judged exactly like a spelled type. * The contract dispatcher's floating-point bindings overflow silently. parseDouble had NO check at all, so ?rate=1e999 reached the handler as an infinity and Json wrote it back as null -- the client got neither its value nor an error. parseFloat had a check that asked !Double.isInfinite(d), which parseDouble("1e999") already satisfies, so every double-overflowing value read as a deliberate infinity. The boxed pair called valueOf directly and had nothing. All four ask the SPELLING now, which is what the controller processor's guards ask. The upload test is the one worth reading twice. Its first version ran four rounds of six 2MB uploads against the DEFAULT 64MB budget -- 48MB, which never reaches the limit -- so it passed with the release deleted and proved nothing. It now runs against a fixture server started with a 16MB budget, where three concurrent 2MB uploads peak at 6MB and pass while three rounds charge 18MB cumulatively: deleting the release fails it in round 2. Ordering itself is not observable from a client, and the comment says so rather than implying the test proves more than it does.

The reservation now happens natively, in the same step as the allocation, against a ceiling Java publishes once; respond() answers false having taken nothing when the body would cross it, and the caller sends a BODILESS 503, since the reason for refusing is that there is no room for bodies. A reservation whose allocation then fails is given back, or the ceiling ratchets down one failure at a time. * A bounded wildcard is a promise, and every consumer was reading it as "claims nothing". List was accepted with no runtime element check at all, so [1] reached the handler as a list holding a Long and the first typed read answered 500 where a 400 was owed. The map-key rule from the last commit was the same bug, patched at one of six sites. Type arguments are normalised where they are PRODUCED now, so validation, the element type, the map value type, the encodability walk and the emitted checks all get the same answer. "? super T" is deliberately not normalised to T -- the value may be T or any supertype, so a check against T would reject what the declaration allows -- and there is a test for that direction too. Both tests earned their assertions the hard way. The h2 one first asked for a 1KB and a 2MB body against a 4MB ceiling, which never accumulates past it, so it passed with every release deleted; it now sends three 2MB bodies, each under the ceiling and summing over it, and fails on the second when the release is removed. That is the same mistake the upload test made in the previous commit, which is a good argument for probing every test in both directions rather than only the one that reads well.

No request satisfies both, and the matcher this check guards handles literals around a variable perfectly well -- but the check called every pair of variable-carrying segments a collision, so a controller that CANNOT be ambiguous failed to compile. Its own doc comment claimed the fixed edges were consulted; now they are. A segment matching both patterns must start with both prefixes and end with both suffixes, so they overlap only when one of each pair contains the other, and a bare "{name}" against "{name}.json" still collides. * A "?" reached the encodable-return check with no dot in it and was approved as a primitive. It is not a primitive, it is UNKNOWN: a handler returning List can hand back a Date or a DTO, which Json writes as a quoted toString() -- the malformed contract this check refuses when the same thing is spelled List. Note this is the opposite of the body rule, deliberately: an unknown element ARRIVING is the client's to shape, one LEAVING is ours to serialise. * The server generator did not recognise a placeholder unless it owned a whole segment, so "/files/{name}.json" -- which the client generator has always substituted, and which therefore already produced a working client -- was refused with "nothing binds {name}". One annotation cannot mean two things in the two halves generated from it. The literals around the value are now part of the match and stripped before decoding. Two placeholders in ONE segment stay unsupported, but they are now refused with a reason rather than silently not matching: "{a}-{b}" gives no way to decide where the first value ends, and a server that guesses binds something the client never meant. That asymmetry with the client is narrower than the one it replaces, and it is loud.

A chunked body was capped per request at 8MB and by nothing at all across requests, so enough unauthenticated clients sending almost that much and pausing before the terminating chunk retain gigabytes while CN1_HTTP_MAX_UPLOAD_MB looks on. It is charged now, against the same counter, reserved before each growth. The figure charged is what the read is RETAINING: the chunks already accumulated PLUS what is buffered on the connection for the chunk in progress. Charging only the accumulator would have missed the second term, which grows to a whole chunk on its own -- the same "fixed one of the two" that put this commit here in the first place. * A request body that is not UTF-8 is answered with 400 instead of being repaired. new String(bytes, "UTF-8") never fails: a malformed sequence becomes U+FFFD, so the handler ran on text the client never sent and whatever validated the body validated the REPLACEMENT. All three readers do it -- fixed-length, chunked and HTTP/2 -- so all three check first. The validator is written out by hand because there is no CharsetDecoder on this target: vm/JavaAPI has Charset and StandardCharsets and nothing else, so CodingErrorAction.REPORT does not exist. It implements RFC 3629 rather than "anything that decodes": an overlong form, a surrogate half and anything above U+10FFFF are each a second way to spell a character, and the second spelling is what gets past a filter that only knew the first. The query-string decoder does the same substitution and is left alone, deliberately and with a comment saying so: refusing a query parameter is a different policy from refusing a body. * A map RETURN keyed by anything but String is refused. Json.writeValue calls String.valueOf on every key whatever its type, so Map answers with keys spelled "[B@1a2b3c" -- object identity, different on every run. The key was being checked as though it were a value, and byte[] is a perfectly good value. rawOn now reads the server's answer when the write fails partway. A server may answer and close before a large body finishes arriving -- a 503 from the budget above is exactly that -- and dying on the write threw away the status that explains why, leaving "Broken pipe" as the whole story. That cost real time here: the leak probe DID fail, and said nothing about how.

So three review threads were answered by code that no reviewer could see and no CI ever built. Empty on purpose. The ref already pointed at the right commit, so a re-push was a no-op and there was nothing to correct in the tree -- only a new commit makes the PR re-read the branch. Co-Authored-By: Claude Opus 5 (1M context) From 9b6f5765de27eda61929b165562ffdff275ac7b2 Mon Sep 17 00:00:00 2001 From: Shai Almog <67850168+shai-almog@users.noreply.github.com> Date: Thu, 10 Sep 2026 05:39:45 +0300 Subject: [PATCH 156/167] Backend: a would-block read is not a hangup, and shutdown frees parked threads * serveOne leaves plaintext descriptors non-blocking in virtual-thread mode, and the zero-copy read mapped every n <= 0 to null -- which the caller reads as the peer having gone away. A chunked upload whose next chunk had not landed yet was therefore dropped mid-request. The native now answers a distinct zero-length array for EAGAIN, and the caller tells the two apart. It does NOT park there, the way readImpl does. readImpl reads into the caller's array; this reads into a buffer that is __thread, so it is shared by every virtual thread multiplexed onto that host, and parking hands the host to one of them whose read would overwrite what this one is about to return. The caller falls back to the copying path instead, which parks correctly and owns its buffer. And only MIDWAY through a message. Between requests a would-block is the ordinary quiet of a kept-alive connection, and reporting it as closed is how the worker is freed; routing those to a parking read made the suite 2.4x slower and stopped shedsIdleConnections shedding anything -- the partial request sat until a deadline and was answered 408 rather than dropped. parsedFromBuffer is exactly that distinction and was already maintained for fill()'s benefit. * stop() left every parked virtual thread allocated. Such a connection has no request in flight, so the drain finds nothing to wait for and goes straight to drop(), which closes the descriptor and returns -- the handle, its native stack and its VM thread registration stay. sweepDeadlines is what normally reclaims them and it runs from the poll loop, which `running = false` has already ended. That matters because releaseVirtualThreadSlot() exists so a server can be started again in the same process. Two things this cost, both worth recording. The first version signalled would-block by setting the SHARED read array's length to zero, which corrupts anything still borrowing it: one header object per host thread, so a connection parsing out of it saw buffer.length become 0 underneath and died with an ArrayIndexOutOfBoundsException inside serveOne. The signal now has its own array. And the first version of the test used a Content-Length body, which goes through fillTo() and the copying path -- it passed with the fix reverted and proved nothing. Only a CHUNKED body reaches the read in question. With the test retargeted, reverting the fix closes the connection during the gap, which is the reported bug exactly. Measured on six pre-existing tests, twice each: 36.75/37.12s with this change against 36.48/37.49s without.

These decode a value the JSON parser has ALREADY typed. A string there is the client disagreeing with the contract, and the generated client could not have produced it. An absent field is still zero: the rule is about a wrong type, not a missing one. The text bindings are deliberately a different path and are untouched. A query, path or header parameter really does arrive as text, so fromText and parseInt parse it -- that is not leniency, it is the only thing that could work. The same split is why a top-level `@Body int` still goes through bodyAsText while `@Body String` requires a real JSON string. Both halves have a test, so the next change to either has to say which it means.

The second pass of an incremental build -- process-classes again, without a clean -- scans target/classes, finds the router or the dispatcher the first pass wrote, and reports a collision. Every project using @RestController failed its second build; a contract could be processed exactly once per clean output directory. Generated classes carry a @Generated marker now and the guard skips them. A hand-written class of the same name has no marker and is still refused -- there is a test for that, because a marker that turns the guard off entirely would be worse than the bug. * A route shape collapsed each segment holding a placeholder to "{}", so "/{name}.json" and "/{name}.xml" were the same shape. The literals are part of it now. That was not the whole refusal. The server kept its OWN copy of the segment-overlap rule, and the copy still called every pair of variable-carrying segments a collision -- the exact thing fixed in the controller processor two commits ago. So a contract the matcher handles was refused here and accepted there. There is one implementation of that rule now, because a rule copied is a rule that gets fixed once. * A contract path without a leading slash never matched. The client resolves it against a base URL and requests /notes; the server split the template to one segment against the incoming two, so the route answered nothing. Templates are normalised to origin-form before splitting, which also fixes the empty template against "/". * Crypto.hashPassword(null) produced a valid verifier. utf8(null) is an empty array, so a handler passing a DTO field the client never sent created an account that verifyPassword("", ...) opens. verifyPassword already refused null; this is the other half, in both runtime arms, asserted by the self-test that runs on both. The marker had to ship in the backend artifact for generated sources to compile against it, which is why maven/backend is rebuilt here rather than only the plugin.

It is clamped now, along with CN1_HTTP_VT_STACK (a stack size) and CN1_HTTP_TARGET_CACHE (an array size, where 0 is a documented "disabled" and only a negative is nonsense). A rejected value says so on stderr and the default is used. The interesting part is what a zero divisor actually does, which is not what the report predicted and not the same on the two runtimes: int zero = Integer.parseInt("0"); 1000 / zero Java SE threw ArithmeticException ParparVM answered 0 Measured, not assumed. So the Java SE dev loop drops the connection with no response -- the reported behaviour -- while the packaged binary quietly loses the rate term of its own deadline and carries on serving. That is worse than a crash in one respect: the difference is invisible until an upload that should have been granted time is cut off with a 408 in production and cannot be reproduced locally. It also means a behavioural test cannot catch this on both arms, because one of them barely misbehaves. A first version of the test sent a body in one write, which fillTo() answers before it ever computes the allowance, so it passed with the guard removed. The test asserts on the clamp's own stderr line instead, which both arms print and the fixture captures -- and the fixture now runs with CN1_HTTP_MIN_BODY_RATE=0 on purpose, so every upload test on that port carries the proof. The clamp is deliberately NOT reachable from the self-test: SelfTest is in com.demo, and making the helper public to test four lines of obvious arithmetic would widen the API for a test's convenience.

The P1 was not, and finding that out took longer than fixing the rest. * NOT a leak. The report was that an HTTP/2 HEAD of a static file never closes its descriptor. responseBodyFor() closes it in a finally, and its own comment says the HTTP/2 caller "comes here for HEAD alone, where the point of this branch is the close below". Adding a close in the bodiless branch as well made it a DOUBLE close -- measured at exactly one extra per request -- which is worse than the reported bug, because a descriptor number is reusable the moment the first close returns and the second lands on whoever took it. The reasoning is now a comment there, since the next reviewer will read the same branch the same way. It took three runs to see, because the metric and the test were both wrong in the same direction: the count ran to -10 and the test's reader scanned for digits only, so it parsed -10 as 10 and reported the leak it was looking for. A measurement that discards the character which disproves the hypothesis is not a measurement. * openStaticFiles is reported now, and means "descriptors this side still has to close". Nothing counted them before, the process limit here is over a million, and a real leak would surface hours later as a server that cannot accept sockets with nothing pointing at the cause. Ownership transfers are recorded at the transfer: a body handed to an HTTP/2 session is freed natively and is counted by Http2.pendingBodyFiles() from then on -- conflating the two made an ordinary h2 GET look like a leak, which is how the distinction got noticed. * The 400 for a malformed UTF-8 body ignored respond()'s answer, so under a full body budget the stream was left unanswered until the connection timed out. It falls back to a bodiless 400. * The HTTP/2 file-descriptor ceiling was checked in Java and taken in C, so every worker finishing at once passed before any incremented -- the same check-then-act already fixed for the byte ceiling, left behind on the descriptor one. Reserved natively now, in the step that takes the descriptor, and the caller closes the fd when refused. * StaticFiles' containment check required root + "/". FileIo.realPath answers backslashes on Windows and openBeneath() is unsupported in the Java SE runtime, so every ordinary child reached that fallback and was answered 403: static files simply did not work in a Windows dev loop. Either separator is accepted; "/srv/wwwroot-evil" is still not inside "/srv/www". The descriptor test pins BOTH directions: +10 is the leak the review predicted, -10 is the fix for it, and 0 is the answer.

The aliasing is the part that matters: %252F is a correctly escaped %2F, and once a bad escape passes through as text, a check written against one spelling is defeated by the other -- and an intermediary that rejects or normalises the invalid form no longer agrees with this server about what was asked for. StaticFiles.decode has refused this all along; these were the copies that did not. Validated once at the entry point rather than inside the matcher. bindFrom() answers a boolean, so a decoder that refused would only turn a syntax error into "no route" -- a 404 for something the client could fix if told. The contract decoder had a second hole: Integer.parseInt(_, 16) accepts a sign, so "%+1" decoded to the byte 1 and "%-1" to -1. Two hex digits, tested as digits. * Tcp.connect forwarded a negative timeout to the native side, which reads every non-positive value as "block with no deadline". Java SE fails immediately out of Socket.connect, so the same call failed fast in the dev loop and hung a packaged server for the OS TCP timeout. Refused now, in the arm that diverged; zero keeps its documented meaning. Database's URL parser already refused this one layer up -- this is the API a caller can reach directly. Both halves of the escape rule are pinned, including that %41 still decodes to A: a guard that refused everything would pass a test written only against the bad input.

A caller that computed an empty slice was told the peer had gone away, but only in production. SSL_read(_, 0) is worse still: OpenSSL leaves it undefined. Answered before dispatching now, on both. write got the same guard: it is harmless today only because its check is n != length and 0 != 0 is false, which is a reason to be explicit rather than to rest on it. * pbkdf2Sha256 with a non-positive iteration count returned the ONE-ROUND result on Java SE instead of failing. The native has always refused it, so a misconfigured SCRAM or key derivation produced a weak key that appeared to work locally -- and a different key from the one the packaged server derives. Both arms refuse it now, and length <= 0 with it, which the native also refuses. * A controller returning a DTO that inherits Json.Writable from a superclass, or implements a subinterface of it, failed to compile. Json.writeValue asks `instanceof Writable`, which honours the whole hierarchy; the check read only the directly declared interfaces. So the build refused what the runtime encodes correctly, which is the worst direction for a build-time check to be wrong in. It walks superclasses and interfaces now, each visited once, and a type with no Writable anywhere is still refused -- there is a test for that side too. The zero-length read is asserted against a real server rather than argued about, which is also how I found that stop() without a drain bound does not return here: the self-test sat past ten minutes before I noticed I had called the wrong one of the two. It uses stop(1000), like the probe above it.

Four threads sharing one in-memory Db lose three of them to "cannot start a transaction within a transaction" and write 30 of 120 rows. Measured, not argued: that is what the new self-test check reports with the synchronization removed. execute, query and transaction now hold the connection's monitor, which is reentrant, so transaction() keeps it across the whole callback and the executes inside re-enter freely. A pooled connection is used by one thread at a time anyway, so it pays an uncontended lock; a shared one is serialized, which is what correctness requires. Both arms, and the demo's claim is corrected. * transferredFields() promised a DTO's inherited fields and stopped at the first superclass this build did not compile, because lookup() sees only the project's own output. A DTO extending a dependency's class lost every inherited field from toMap() and fromMap() -- silently, on both ends, so the two agreed about a value neither sent. Fixing that alone would have made things WORSE: the generated codec then names the dependency's types, and this processor compiled its generated sources against the output directory alone. A silent omission would have become a build failure. The compile classpath is included now, as the controller processor already did. * A parameter carrying two binding annotations silently bound whichever the priority chain reached first. For @RequestHeader("Authorization") next to @RequestParam("token") that is the difference between a header a proxy controls and a query string the caller writes, and the declaration named both so no reader could tell which won.

A StackOverflowError out of a recursive parser -- which this server already has a test about -- or an AssertionError from a handler walks past all of them and leaves serveOne without reaching any drop(). The descriptor has been removed from its poller by then and is still in liveConnections, so nothing will ever close it: one stranded socket per occurrence. serveOne is now a wrapper that releases and rethrows; a wrapper rather than a try around the body because the body has many returns and the point is that every one of them is covered. * Two hex digits is not enough to call an escape valid. %C3%28 is a truncated two-byte sequence, and new String(_, "UTF-8") answers U+FFFD instead of failing -- so the handler received exactly what %EF%BF%BD%28 produces. One value, two spellings, which is the same aliasing the escape-syntax check was added for one level up. Both generators validate the decoded bytes as UTF-8 now (RFC 3629, so overlong forms, surrogate halves and anything above U+10FFFF go too), and there is a test that %C3%A9 still decodes to one accented letter, because that is the direction this kind of guard breaks. The third finding in the batch is REFUSED, and the reasoning is now a comment on the constructor it names. It said the HTTP/2 Request leaves pathLength at Java's default 0, so every generated route 404s over HTTP/2. pathLength carries a field initializer (= -1), and javac copies those into every constructor: that constructor's bytecode opens with iconst_m1/putfield pathLength. Checked with javap rather than by reading, because the sibling constructor assigns it again explicitly and this one therefore looks like it forgot.

Postgres and MySql each own a Wire, and a Wire owns ONE 16KB buffer with a position and a limit plus one output stream every message is built in; MySql also carries the packet sequence number. Two handlers sharing a Database therefore write into the same message buffer and move each other's parse position -- protocol corruption, not merely one request's rows committed by another's COMMIT. Measured against a real PostgreSQL rather than argued from the source: with the lock 28s, every transaction wrote both its rows without the lock 661s, four threads dead, zero rows The unsynchronized run does not fail fast, it WEDGES: pg_stat_activity showed the connection still 'active' while the client waited for a reply that the desynchronized stream would never produce, and the run only ended when the test's own 60s joins expired. A hung connection per request is the failure a reviewer would meet in production. execute, query and transaction now hold the Database monitor. The SQLite path then takes Db's monitor underneath -- always in that order, never the reverse, so there is no cycle -- and both are reentrant, which is what lets transaction() keep the session across the whole callback. The check lives in DbCheck, which runs against every configured engine on both runtimes, so CI covers Postgres and MySQL where it supplies them. It drops its table before creating it: the finally cannot fire if the run is killed, and the next run against a SHARED server then meets "relation already exists" -- one interrupted run failing every run after it. That happened here while A/B-ing this fix. Unrelated to the fix: the self-test's zero-length-read probe connected with a 2s timeout and failed once, beside the HTTP suite's four servers, in a way I could not reproduce in three attempts. The timeout is 15s now. Its outcome string already distinguishes "threw" from a wrong number, so a real failure there will still say so rather than hiding behind the timeout.

One file, two spellings, one of them checked. Utf8.isValid was sitting in the same package; this decoder is the third copy of the rule and the last one that did not use it. Its parseInt(_, 16) took a sign as well, so "%+1" spelled the byte 1 a third way. Two hex digits, tested as digits, like the generated decoders now do. * @ResponseStatus on a method that returns HttpServer.Response is refused. emitRoute returns the handler's Response untouched, so the annotation named a status that could never be sent. Refused rather than applied: overwriting the status of a Response the handler built would be the more surprising of the two, since it may already carry headers and a body chosen to match it. * required=false on a primitive query or header parameter is refused unless it has a defaultValue. The converter substitutes 0 or false, so the handler cannot tell an omitted value from a client that sent zero, while the annotation documents optional as null-bearing. The first version of that error told the developer to use a boxed type. Path, query and header parameters bind to String and the primitives only, so that advice was impossible to follow -- the test for the accept side is what caught it. It recommends a defaultValue now and says why a boxed type is not the way out here. Each rule has a test for the shape it must NOT break: a Response return without the annotation still sends the handler's own status, a defaulted primitive and an optional String still compile, and caf%C3%A9.html still reaches the lookup instead of being refused as malformed.

A conforming proxy in front rejects all three -- and a server that frames a message differently from the intermediary ahead of it is the whole of request smuggling, which is why this parser already refuses bare LF and obsolete folding. The trim() went with it: HTTP does not allow space around the size. This was the FOURTH time the same leniency produced a defect here, after percent escapes in static paths, in generated routers and in generated dispatchers. So it is one implementation now (Hex), not a fifth copy: the JSON \u escape used the same call and accepted "\u+041", and StaticFiles' private copy now defers to it too. * addPet ran the insert and lastInsertId as two synchronized calls rather than one operation. The connection is the same -- the comment there was already right about that -- but Db locks per call, so a second request could insert in the gap and hand the first response the other pet's id. It runs in a transaction now, which holds the connection across both. * A malformed port put the whole database URL, password included, into an IOException that goes to a log. describe() exists precisely to keep passwords out of strings like that; this error path bypassed it. The chunk test pins the accept side too -- a plain "5" and a "5;ext=1" extension both still frame a body -- because a size parser that refused everything would pass a test written only against the bad spellings.
