Conversation
… the terminal A tool call or a fresh session reads a captured output file, gets interrupted mid-run, and starts cold. Two things in the wrapper tripped that caller: an interrupt left pio's build tree running with no record of it (the next invocation started a second build into the same .pio/build/, or pgrep'd and matched itself); and pio's own "[PASSED]" / "N succeeded" lines made a half-finished output file read as green. run-tests.sh: - Run record in .pio/runtests/current.tsv for the life of a run. A second invocation prints RESULT: BUSY and exits 4 without touching the build directory. Valid while the holder pid OR the recorded process group is alive, so a SIGKILLed wrapper with live scons children reads ORPHANED rather than clear. - --status / --wait / --abort. --abort kills the whole tree by pgid. - pio runs under setsid with its pgid recorded; INT/TERM/HUP kill the tree and record RESULT: ABORTED (exit 5), log kept. - One result() for every verdict: prints to the stdout the script started with (a signal can arrive inside a redirected pio call) and writes .pio/runtests/last-result.tsv with head, args, env, finish time, kept log and a tree fingerprint (HEAD + working-tree diff + untracked files). --status marks the last verdict STALE when the tree has changed since. - Banner naming the final RESULT: line as the only verdict. - Non-Linux host: RESULT: UNSUPPORTED, exit 6, instead of the AMBER code. - A failed build removes .pio/build/<env>/meshtasticd, which run bare would reprint the last good run. - FILTERED lists the not-run count, not 77 suite names. bin/run-tests.cmd forwards into WSL with the exit code passed through, so the same command line works from cmd.exe and PowerShell; no logic is duplicated. test/README.md, copilot-instructions.md and the mirrors document the new codes and the rule.

the hard-coded suite totals, using a symbolic placeholder or omitting the total
while preserving the filtered-suite meaning.
In `@bin/run-tests.sh`:
- Around line 281-294: The --wait flow currently tracks only the initial state,
allowing it to follow a later run or read a stale verdict. Update the run-record
and result-record handling around run_state, current.tsv, and last-result.tsv to
persist a unique run ID, capture the observed ID when waiting starts, and wait
for that specific run; return only its matching result, or ABORTED if it
finishes without a matching verdict.
- Around line 338-342: Update the run-start path around run_state() and
current.tsv to acquire a short-lived exclusive lock before checking state and
creating the run record, keeping the lock through the IDLE validation and record
publication. Write current.tsv via a temporary file and atomically rename it
into place, then release the lock only after the record is complete; preserve
existing handling for RUNNING and ORPHANED states and ensure --status cannot
observe or remove a partial record.

… freezing the counter Measured on a full native run: the warm-up, `pio test --without-testing` with no filter, builds AND links every suite - 78 links, 2320 s, 29.7 s each, 39 minutes before the first test ran - and prints a "[PASSED]" line for each program it merely linked. CI never did this; its warm-up is one `platformio run`. The shared src objects are the same whichever suite links them, so the warm-up now links one: the filtered suite when there is one, else test_utf8. The run itself still builds every suite, as it must. The heartbeat counted objects newer than its marker, which sits still through PlatformIO's single-threaded scons dependency scan and through each link - twelve minutes at "430/754 objs, ETA 17m" on that run, which reads as a hung build to a caller who cannot run ps. It now names the phase from the processes in the recorded group: [scons] / [compile] (with the ETA) / [link] / [test], and --status prints the same phase word.

🟠 Major · Return code 5 after an actual --abort.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick winReturn code 5 after an actual
--abort.
abort_cmdrecords or waits for anABORTEDresult with code 5, then exits 0 on every non-idle path. The CLI contract inbin/run-tests.shandtest/README.mddefines code 5 asABORTED, including runs stopped by--abort. Automation therefore treats an aborted run as a successful command. Keep exit 0 for the idle “nothing to abort” case, but return 5 after an actual abort.🤖 Prompt for AI Agents

…record publish Review findings on meshtastic#11862, all three valid: - --wait stored a state and then waited for any record to clear, so a run that finished and a second that started between polls would be followed to the second's verdict, and a run that turned ORPHANED mid-wait could print a stale last-result. Each run now has an id (pid-start) in current.tsv and last-result.tsv; --wait captures it and reports only a matching verdict, else ABORTED-without-verdict. - run_state() then the current.tsv write was a check-then-act pair: two invocations in the same instant could both see IDLE. The pair is now one critical section under a short-lived flock, and both records are published by rename so no reader can see a partial file. The record stays the ownership token; the lock only serializes the handoff (a SIGKILLed holder releases flock but not the record, which is why flock alone was rejected). - The FILTERED and AMBER examples in copilot-instructions.md carried a literal suite count, which the same document says never to do. Verified on a live run: --status RUNNING, a concurrent start refused BUSY, a --wait started before --abort reported the aborted run's own verdict with the matching id, exit 5; no build process survived.
What
bin/run-tests.shgains a run record,--status/--wait/--abort, process-group ownership of thepiobuild tree, a persisted last verdict, and three new exit codes. Plus a WSL forwarder (bin/run-tests.cmd) and the matching doc updates. No change to the verdict logic, the shared-state check, shards or CI.Why
The wrapper was written for a human at a terminal. A caller that reads a captured output file and can be interrupted mid-run (a tool call, a backgrounded job, a fresh session) trips over two things:
EXIT, to delete its temp logs. Kill the shell andpio → scons → cc1pluskeep running with no lock, no pid file, and the log gone. The next invocation either starts a second build into the same.pio/build/(andrm -rfs the running run's state summary), orpgrep -fs and matches itself.[PASSED]per suite andN succeededper invocation long before the wrapper'sRESULT:line exists, so a partial output file reads as a completed green run.How
.pio/runtests/current.tsv(pid, pgid, start, args, HEAD, log, progress) for the life of a run; removed by the oneresult()function every verdict now goes through. A second invocation printsRESULT: BUSY, exit 4, and touches nothing. A record is valid while the holder pid or the recorded process group is alive —flockalone would not do, since a SIGKILLed holder releases the lock while its scons children live on; that case reports ORPHANED and only--abort(or the tree finishing) clears it.--statusprints RUNNING / ORPHANED with progress, or IDLE with the last verdict.--waitattaches and exits with the verdict.--abortkills the tree by pgid from any shell.pioruns undersetsidwith its pgid recorded;INT/TERM/HUPkill the tree and recordRESULT: ABORTED(exit 5), log kept. Ctrl-C at a terminal now actually stops the build..pio/runtests/last-result.tsvwith the kept log, plus a tree fingerprint (HEAD + working-tree diff + untracked files by content).--statusrecomputes it and marks the verdict STALE when the tree has changed — persisting a verdict without this would make "a GREEN from before the current edits" the most convincing false green there is.result()prints to the stdout the script started with (fd 3): a signal can arrive inside a pio call whose stdout is redirected to a log, and the verdict was disappearing into it.RESULT:line as the only verdict.RESULT: UNSUPPORTED, exit 6 — it used to exit 2, the AMBER code, which reads as "ran, passed with caveats"..pio/build/<env>/meshtasticd, which run bare would reprint the last good run. (An mtime check is not usable: an unchanged tree legitimately skips the relink.)bin/run-tests.cmd:wsl.exe --cd "%~dp0.." -e ./bin/run-tests.sh %*, exit code passed through. A forwarder, not a port — the header's argument for staying Linux-only stands, and CI never runs the native suite on Windows.Exit codes 0–3 are unchanged. Everything new is keyed on the checkout's own
.pio/, so separate worktrees still run independently.Verified
On WSL2:
--statusIDLE; a stale record (dead pid, dead pgid) self-clears; a real-e native -f test_utf8 --quietshows RUNNING with the whole compiler tree in its own pgid; a concurrent invocation getsBUSYexit 4;--abortfrom another shell leaves noscons/cc1plussurvivor and records ABORTED; a run to completion prints exactly the banner (stderr) andRESULT: FILTERED …(stdout), exit 3, and--statusthen reports it — marked STALE after a further edit.trunk fmtclean.Not exercised:
drop_stale_program()needs a failing build;run-tests.cmdneeds a Windows shell — a checkout on the WSL filesystem (\\wsl$\…path throughwsl --cd) is the case to try first.Summary by CodeRabbit
