fix(store): gate globals, servers and remote devices against every other element name [DOPE-598 + DOPE-600] - #1097
Conversation
…her element name (DOPE-598, DOPE-600) Move the element-name gate into its own module and split it into two namespaces: compiler symbols (POUs, data types, global variable lists, resource globals, library symbols, unparsed .dt files) and workspace registry (POUs, data types, lists, servers, remote devices). A name is checked only against the kinds it shares a namespace with, so a server may still be named like a global or a library function, while a global named after a POU, a type or a list is refused. Servers and remote devices now go through the gate on create, rename and duplicate. Rename had no check at all: renaming onto an existing server left `files` keyed by the stale name, and a same-name rename queued the server's own file for deletion. Case-only renames are refused for both, since they own a file and the file systems we ship on fold case. Resource globals are checked at both store entry points and at the code view's commit boundary, so the undo path through `setGlobalVariables` stays ungated. The three "+" paths in the globals editor now surface the refusal as a toast instead of dropping the response. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
WalkthroughThe change centralizes case-insensitive name collision checks across project, compiler, library, file, EtherCAT, and global-variable namespaces. Creation, duplication, renaming, copy naming, and global-variable editing now use these checks. Tests cover collision rules and auto-increment behavior. ChangesName collision validation

Mirror review of https://github.com/Autonomy-Logic/openplc-web/pull/746 — the two diffs are byte-identical (verified locally, and
sync / Shared Surface Syncis green on both), so every point below applies verbatim to this PR.
Review — needs changes
The design is right: one gate, two overlapping namespaces instead of one pool, the COMPILER_SYMBOL / WORKSPACE_ELEMENT / OWNS_FILE tables read as the rule itself, and the 6×5 matrix runs against the real store with DISJOINT enumerated independently of the production tables, so it is not a tautology. Extracting the gate into its own module was the right call and the files-registry reasoning behind refusing case-only renames is correct.
Two things stop it: the namespace does not close in both directions for one pair, and three of the paths that can now refuse do not tell the user why. Details below, all verified against the branch.
Must fix
1. store/slices/shared/name-collision.ts:204-227 — the derived <name>_TYPE block omits resource-global, so the collision is order-dependent.
A resource global that takes a list's type name is refused at :191-195 (listOwningTheName, reached because COMPILER_SYMBOL['resource-global'] is true). The mirror block for a new list checks data-type (:205), pou (:208), the other lists (:213, :216), unparsed .dt (:221) and library symbols (:224) — but not resource-global.
Repro: create a resource global named Plant_TYPE, then a Global Variable List named Plant → accepted. Do it in the other order → refused. The result is the generated struct Plant_TYPE next to a VAR_GLOBAL Plant_TYPE — exactly the duplicate symbol this family exists to prevent, reachable only by choosing the order. CodeRabbit flagged this too and its suggested arm is correct:
if (others.some((o) => o.kind === 'resource-global' && nameMatches(o.name, derived))) {
return `"${name}" needs the type name "${derived}", which a global variable already uses`
}Should fix
2. store/slices/project/slice.ts:1055 + store/slices/project/validation/variables.ts:341-345 — the globals "+" button can be permanently refused.
The gate runs after createVariableValidation, and that auto-increment is single-shot: checkVariableName derives one candidate from the globals table only (${nameWithoutNumber}${biggestNumber + 1}) with no retry against the namespace. The candidate is a pure function of the table, so every subsequent click produces the same refused name, and handleCreateVariable only toasts and returns.
Concrete dead end: a POU named GlobalVar plus an empty globals table → the "+" button hardcodes GlobalVar (components/_organisms/global-variables-editor/index.tsx:229-243) and the table can never get its first row. Same shape for any base name whose <base><n> lands on a POU, a data type, a list, a list's _TYPE, an unreadable .dt, or one of the installed library symbols.
Suggested fix: loop the candidate while elementNameCollision(state, candidate, 'resource-global') !== null (bounded, like MAX_AUTO_INCREMENT_ITERATIONS), or pass a nameTaken predicate into createVariableValidation so the auto-increment sees the whole namespace rather than just the table.
3. components/_features/[workspace]/create-element/element-card/index.tsx:220-237 — the create form states the wrong reason for servers and remote devices.
handleCreateServer and handleCreateRemoteDevice call serverSetError('name', { type: 'already-exists' }) / remoteDeviceSetError(...) with no message and no toast, and the form renders fixed text: * Server name already exists or protocol already in use (:512-516) and * Device name already exists (:647-651).
After this PR those two actions can refuse with "Main" is already the name of a POU, … of a data type, … of a global variable list, or the unreadable-.dt message. Repro: POU named Pump, create a server named pump → the form says a server with that name exists; the user opens the servers branch, finds none, and has no way to learn the real reason.
The list and data-type handlers in the same file (:171-185, :200-215) already do this correctly, with a comment saying why — the refusal is often about a POU or a global variable list, not another data type, so the reason has to reach the user. Worth applying the same shape here: pass result.message through and render errors.name.message ?? '<existing fallback>'.
4. components/_molecules/project-tree/index.tsx:302-313 — an EtherCAT remote-device rename now fails silently.
ProjectTreeExpandableLeaf.handleRenameFile does setNewLabel(label); return on failure, with no toast. That component is what renders EtherCAT devices (components/_organisms/explorer/project.tsx:549), and before this PR remoteDeviceActions.rename had no cross-kind check, so the branch was effectively unreachable. Now renaming an EtherCAT bus onto a POU / data type / list / server name snaps the label back with no explanation.
ProjectTreeLeaf next to it already handles this via reportFailedRename (:619-627), whose own comment makes the position explicit: "Snapping the label back is not an explanation: element names share one namespace, so a refusal usually names a POU, data type or list the user cannot see from here." toast is already a module import at :41, so this is a two-line change.
5. components/_organisms/global-variables-editor/index.tsx:358-364 — the code-view gate re-validates rows the commit does not touch.
commitCode loops over every parsed variable with no ignoring and throws on the first collision. Global names were never gated before this PR (origin/development's createVariable has no gate and setGlobalVariables still has none), and the gate includes the whole installed library pool — PID, Scale, Ramp, Delay and friends are all refused for resource-global while isLegalIdentifier accepts them, i.e. names an existing project can already hold.
For such a project: every code-view commit is refused, including one that edits an unrelated row; handleVisualizationTypeChange:191-194 then refuses to go back to the table view (if (!success) return); and the click-outside autocommit re-fires the failure. The acceptance criterion "an existing project already carrying such a collision still opens" holds — but the project becomes uneditable through this view.
Suggested fix: skip any parsed variable whose name is already among state.project.data.configurations.resource.globalVariables (case-insensitively), so only names the commit actually introduces are gated. Also worth a title other than Syntax error at :382 for a namespace refusal.
Tests
6. store/__tests__/shared-slice.test.ts:1463 — leaves the file registry alone when the rename is refused passes unchanged on development, so it does not pin the bug it is named after.
On development, projectActions.updateServerName (store/slices/project/slice.ts:1705) already refuses an exact-match duplicate before any setState, and renameElement propagates that at store/slices/shared/slice.ts:210-211. So files was never corrupted on the exact-duplicate path.
The path that did corrupt it is the case-only rename, which updateServerName's === check let through: it pushed devices/servers/OldServer.json onto pendingDeletions while writing oldserver.json — the same file on a case-folding disk. That test (:1472) asserts only .ok. Moving the registry assertions there would give DOPE-600's headline criterion a test that can actually fail:
expect(state.files['OldServer']).toBeDefined()
expect(state.files['oldserver']).toBeUndefined()
expect(state.project.data.servers?.[0].name).toBe('OldServer')
expect(state.pendingDeletions).toEqual([])7. remoteDeviceActions.rename has no action-level test for either new branch — neither the case-only refusal nor the oldName === newName no-op. The gate-level case (name-collision.test.ts:107) does not prove the action passes oldName as ignoring or that renameElement is skipped, and vitest.config.ts sets branches: 0 for store/slices/, so the coverage gate cannot catch it. The two server tests mirror over directly.
8. global-variables-editor has no test file anywhere in the repo, so the three new toast paths (:240, :268, :285) and the code-view gate (:358) are entirely unexercised — including the regression in point 5. Also missing: a test for "an existing project already carrying such a collision still opens" (it holds by construction today, since no gate runs on the open path, but nothing pins it).
Nits
name-collision.ts:104-116— EtherCAT slaves are outside the pool, yet they own afiles[name]entry (components/_features/[workspace]/editor/device/ethercat/index.tsx:553) and rekey editor/tabs/files on rename (shared/slice.ts:902-906), while the module header claims to cover "every kind that has a tab".ethercatDeviceActions.renamestill checks onlycollectAllSlaveNames. Probably a follow-up card in the family rather than growth here — but the header comment should not overclaim in the meantime.project-tree/index.tsx:687-697—allElementNames, which feedsnextCopyName, still excludes resource globals and derived_TYPEnames, so Duplicate can propose a name the widened gate refuses, forever (same pure-function problem as point 2). E.g. POUMainplus a global namedMain_copy.components/_molecules/global-variables-table/editable-cell.tsx:98-114— the rename-impact modal is awaited before the new gate runs, so the user answers "rename N blocks?" and only then learns the name is taken. The illegal-identifier check at:90runs before the modal, so the file's own convention is name-first.store/slices/project/slice.ts:1110-1115— the gate runs before the target row is resolved, so an update dispatched with a stalerowIdreportsVariable already exists: …instead ofVariable not found.
Two claims in the PR description that the code does not support
- "A resource global can no longer be named after … an unparsed
.dtfile" — it can.name-collision.ts:183gates that check onWORKSPACE_ELEMENT[kind], which excludesresource-global, andname-collision.test.ts:136assertsgate('broken','resource-global')isnull. The code looks defensible to me — the transpiler emits fromproject.data.dataTypesandunparsedDataTypeFilesis never referenced undersrc/backend, so the file is echoed to disk but not compiled — so it is the description that needs the correction, along with the pre-existing comment atname-collision.ts:219-220that asserts the opposite. - "
updateServerNamequeues the old file for deletion, so a no-op rename would mark the server's own file deleted on the next save" (shared/slice.ts:702-703, and the same for devices at:790-791) — it would not:updateServerName:1705andupdateRemoteDeviceName:2027already refuse an identical name before reaching thependingDeletions.push. The early return is still worth keeping (it makes the no-op contract explicit and returnsok: trueinstead of a spurious failure), but the justification is not the one written down, andexpect(pendingDeletions).toEqual([])atshared-slice.test.ts:1478cannot fail as a result.
Finally, "Validated manually … every refusal in both directions" is a bit stronger than what is there: point 1 is a direction that is not refused, and points 3, 4 and 5 are paths where the refusal does not reach the user.
…, DOPE-600) The derived `<list>_TYPE` check now also looks at resource globals, so the list/global pair is refused in either creation order. EtherCAT slaves join the workspace namespace as their own kind: slave rename, scan-bus add, repository add and bus duplication go through the gate, `generateUniqueSlaveName` takes a predicate so the add paths keep auto-suffixing, and the other workspace kinds refuse a slave's name. The globals "+" button feeds the gate into the row validator's auto-increment instead of refusing the candidate, so a POU holding the seed name no longer blocks the table forever. The code view gates only the names a commit introduces, so a project that already carries a global named after a library symbol stays editable through it. The server and remote device create forms, the EtherCAT bus rename and the globals table cell now report the gate's reason, the cell before the rename-impact modal; Duplicate picks its `_copy` name through the gate; `updateVariable` reports a missing row before judging its name. Tests pin the case-only rename against the file registry for servers and devices, cover the auto-increment loop and its bound, the code-view helper, the slave paths, and a project that already carries a collision still loading.

Mirror of https://github.com/Autonomy-Logic/openplc-web/pull/746 — I verified the two diffs are byte-identical, so this review applies verbatim.
Review round closed — approving
I verified every item against the code on the follow-up commit rather than taking the summary, and all of it holds.
Must fix
- The derived
_TYPEarm now carries theresource-globalcase (name-collision.ts:216), and the matrix test covers both creation orders — a global namedPlant_TYPEbefore the listPlant, and the reverse. The order-dependent hole is closed.
Should fix
2. createVariableValidation takes a nameTaken predicate, folds it into taken() and now loops the candidate under MAX_AUTO_INCREMENT_ITERATIONS (variables.ts:332,342,346). The predicate is passed only for scope === 'global', so no other caller changes shape, and the post-validator gate stays as a bound backstop. The dead end I described is a test now: POU GlobalVar plus an empty table yields GlobalVar0.
3. handleCreateServer / handleCreateRemoteDevice pass result.message into setError and toast it, and the form renders errors.name.message ?? <the old fallback> (:524, :659) — the same shape the list and data-type handlers already used.
4. ProjectTreeExpandableLeaf.handleRenameFile toasts the reason before snapping the label back, so the EtherCAT bus rename no longer fails silently.
5. commitCode goes through newGlobalNameCollision, which skips every name the globals table already holds (case-insensitively) and gates only what the commit introduces. A project carrying PID or Scale stays editable through the code view and can return to the table, and the refusal is titled Variable already exists instead of Syntax error.
Tests
6. The exact-duplicate registry test is gone and the assertions moved onto the path that actually corrupted the registry: the case-only rename test now pins files, the element name and pendingDeletions, for servers and for remote devices.
7. remoteDeviceActions.rename has the case-only, same-name no-op and cross-kind cases at action level.
8. The code-view gate became a pure helper with its own four-case describe — including one that proves the skip is real (gate('Scale', 'resource-global') refuses while check('Scale', 'Level') passes) — plus a store test that a project already carrying a server/list collision loads with both elements present.
Declining the global-variables-editor component test is fine by me: Monaco in jsdom is a harness, not a test, and the substantive half of that item became a tested pure helper. Worth its own card rather than this PR.
On the EtherCAT slaves. That was a nit and it came back as a new kind in the gate, wired through ethercatDeviceActions.rename, scan-bus add, repository add and bus duplication, with generateUniqueSlaveName taking a predicate so the add paths keep auto-suffixing. Scope growth inside a review round is the thing I would normally push back on, but it arrived with real coverage — the kind matrix, its own same-kind message, the case-only rule, the unreadable .dt case, eleven action-level cases for the rename and slave duplication in element-duplicate.test.ts. Judged on the code, it is better than the follow-up card I suggested.
Gates. CI green on both PRs. I compared the two diffs directly, not only via the sync check: byte-identical. The description corrections are real — the mirror link is back, the claim about an unreadable .dt standing in a global's way is now stated correctly as the opposite, and the no-op rename is justified by the mechanism that actually applies rather than by a deletion that never happened.
Two leftovers, neither blocking
collectAllSlaveNamesno longer has a production caller:allElementNamesis gone and the EtherCAT paths use the gate predicate, so only the definition and its six tests remain, whilenamedElementscollects slaves inline. Worth deleting, or keeping with a line saying why if something outside the shared surface still uses it.- One new
asinunique-slave-name.ts:40(existing as NameTaken), avoidable by restructuring the ternary so the narrowing carries. The commit's other casts areas constor test fixtures.
Both are cosmetic and fine as a follow-up. Approving.

Bug fix: no Requirements Gathering page, and no Cybersecurity Risk Assessment trigger area is touched — store validation and one toast in the globals editor.
Problem
Two holes in element-name uniqueness, one card each:
createVariable/updateVariableonly checked the globals table itself, and the globals code view committed whatever parsed. The compiler then saw two symbols with one name.files[]keyed by the stale name (the old file was never dropped, the new name pointed at nothing), and renaming a server to its own name queued its own file for deletion on the next save.Both cards are the last two children of the DOPE-577 family, so they land together: they share the gate, and fixing one without the other leaves the same class of collision open from the other side.
Fix
The gate moves to its own module —
store/slices/shared/name-collision.ts— so the project slice and the globals editor can call it (it lived insideshared/slice.ts, unreachable fromproject/slice.tswithout a cycle).elementNameCollision(state, name, kind, ignoring?)is the single entry point;nameMatchesis re-exported for the callers that still need a plain compare.Two namespaces, not one pool. A kind is checked only against the kinds it shares a namespace with:
So a server may still be named like a resource global or like a library function (
Scale), because neither reaches the compiler through the server; a resource global namedScale, or after a POU, a type or a list, is refused. The<name>_TYPElist check, the library-symbol check and the unparsed.dtfile check keep their existing scope and messages verbatim.Servers and remote devices go through the gate on create, rename and duplicate. Rename checks the new name with the old one as
ignoring; a same-name rename is an explicit no-op (without itupdateServerNamematches the element against itself and reports a duplicate). Since both kinds own a file, case-only renames are refused like they are for POUs — the file systems we ship on fold case, soModbus→modbuswould pushdevices/servers/Modbus.jsonontopendingDeletionswhile writing the same file under the new spelling. The same-kind messages areServer already exists/Remote device already exists. The create form and the EtherCAT bus rename now carry the gate's reason to the user instead of a fixed "already exists" or a silent snap-back, and Duplicate picks its_copyname through the gate so the second duplicate lands on the first try.Resource globals are gated at both store entry points.
createVariablefeeds the gate into the row validator's auto-increment (createVariableValidationtakes anameTakenpredicate, bounded like the location loop), so the "+" button's clone steps past POU, type, list and library names the same way it steps past its own table — a POU namedGlobalVarno longer blocks the first row forever.updateVariablechecks only whennamechanges and only once the row is found, ignoring the row's current name so a case-only edit of a global stays allowed (globals own no file). The globals code view runsnewGlobalNameCollisionat its commit boundary: only names the commit introduces are gated, names the table already holds pass, so a project that already carries a global named after a library symbol stays editable through that view; the undo path throughsetGlobalVariablesstays ungated. The table's name cell checks the gate before asking about reference propagation. The three "+" paths in the editor surface a refusal as a toast; they used to drop the response silently.Not touched: undo/redo, project load (a project already carrying a collision still opens), the Requirements/CRA pages, any backend.
Behaviour changes worth knowing

From Gustavo's review: the derived
_TYPEarm now checks resource globals (order-independent); the globals "+" auto-increments against the whole namespace instead of dead-ending; the server/device create form and the EtherCAT bus rename report the gate's reason; the code view gates only introduced names; Duplicate's_copyname goes through the gate; the table cell checks the name before the rename-impact modal;updateVariablereports a missing row before judging its name; comments and this description corrected (unparsed.dtvs globals, the no-op rename reason). EtherCAT slaves join the workspace namespace as their own kind:ethercatDeviceActions.rename, scan-bus add, repository add and bus duplication all go through the gate (generateUniqueSlaveNametakes a predicate, so auto-suffixing still steps past a taken name instead of refusing), and every other workspace kind refuses a slave's name. The same-kind message for slaves is unchanged.Shared surface:
