Conversation
saveCurrentFile() saves whichever tab has focus and returns true as soon as the save is dispatched. A plugin editing an unfocused file therefore had to steal focus first, and openFile() only posts the tab switch - so the save read a stale tab index, persisted the user's other tab, and reported success. saveFile(file) removes focus from the causal chain: it resolves the editor by File, blocks until the write completes, and returns whether the bytes are on disk. A clean buffer counts as saved - CodeEditorView.save() reports "nothing to do" and "write failed" with the same false - and a completed write is verified by byte length to catch truncation. The permission check follows the file-targeted surface (requireWrite + ensureFileAccessible) rather than writableCurrentFile, which inspects the focused file. saveCurrentFile() stays as the "save what the user is looking at" primitive. Guards: the call rejects the main thread up front, since the save itself runs there and blocking from it would deadlock until the timeout. setFilesSaving now resets under NonCancellable so a timed-out save cannot leave the Save action disabled for the session.

Move the count into the flag's main-thread section: off-main it decremented to zero and queued false, which landed after a main-thread save had set true inline.

A failed assertion skipped the looper drain, parking the non-daemon worker on a main-thread hop that never ran. Wrap the body in try/finally, drain and bound the join there, and mark the worker daemon.

Automated code review (xhigh). 13 findings, F01-F13, posted inline.
Likely real bugs: F01 (the fix is defeated by activity recreation), F02 (plugin saves of .gradle.kts/.xml skip sync and generateSources()), F04 (counter can latch the flag on permanently), F05 (double resolution can save the wrong buffer).
Also: F03 main-thread disk IO under StrictMode, F06 unbounded wait / ANR path, F07 stale tab index after the write, F08/F09 doc accuracy and the missing PLUGIN_API_CHANGELOG.md entry, F10-F13 test robustness, coverage gaps, and cleanups.

F01/F13 The save counter moves into EditorViewModel, next to the areFilesSaving flag it guards. The ViewModel is retained across activity recreation while the activity is not, so a save still running under NonCancellable against a destroyed instance no longer clears the flag for a save the recreated instance had already started. Being main-confined by construction now, it is a plain Int rather than an AtomicInteger. F04 The count is floored at zero. Left negative by an unbalanced call, the "reached zero" test never matched again and SaveFileAction stayed disabled for the life of the ViewModel. F12 saveFileResult resolves the editor before raising the flag, so a save with nothing to do (file not open, or buffer already clean) no longer emits true/false for a no-op. F03 The file stat runs on Dispatchers.IO; debug builds install StrictMode's detectDiskReads on the main thread. F05/F07 The write takes the CodeEditorView, not a tab index. The file was being resolved twice through two different indexing schemes with nothing asserting they agreed, and the tab to unmark was resolved from an index captured before a suspending write - a tab closed during a large write stripped the asterisk from the wrong tab. F02 The SaveResult is consumed, as every other save path does: a plugin that saves a Gradle script gets the sync prompt, and one that saves a layout gets generateSources() so R fields for its new resources exist. F06/F08 EditorProviderImpl.saveFile bounds its wait, and its KDoc no longer claims the write runs on the main thread - CodeEditorView.save marshals it to its own write thread. Both KDocs now say plainly that a runBlocking bridge on the main thread deadlocks on the resumption hop. F09 PLUGIN_API_CHANGELOG.md records saveFile so an author can floor plugin.min_ide_version rather than hit the silent default false. F10 The overlapping-save test drains the looper before waiting on it. isIdle reports "nothing queued", not "the worker posted", so a leftover startup message satisfied it immediately. F11 Adds coverage: the plugin-facing SecurityException contract on IdeEditorServiceImpl.saveFile, the no-open-editor and detached-provider false paths, the flag not flapping for a no-op save, and the counter's overlap and floor semantics. Still uncovered - they need a live editor view: clean-buffer-returns-true, a write throw becoming false, and the CancellationException rethrow.

beginFileSave() moves inside performFileSave's try. Its block is guaranteed to run - the context's job is NonCancellable - but withContext still honours prompt cancellation on resume when the caller is off-main, so it could increment the count and then throw past an un-armed finally. The retained counter made that latch areFilesSaving on for the rest of the session. OverlappingSaveFlagTest now pins the precondition: the flag is raised even though the call throws. The write runs off the main thread on every path. saveFileResult, saveResult and saveAllResult each dispatch to IO, because saveEditorInternal stats the file - CodeEditorView.save's own pre-check plus the timestamp bookkeeping - and both plugin entry points could arrive on Main: saveFile from a plugin coroutine, saveCurrentFile via lifecycleScope. That makes the public KDoc's "any dispatcher, the main one included" true rather than aspirational. Editor and view-container access moves back onto Main: frag.file and frag.isModified are read in one Main.immediate hop, hasUnsavedFiles() and getEditorAtIndex() get their own. CodeEditorView.save's internal ordering is unchanged and shared with saveAll, so it stays out of scope here. The write plus its bookkeeping is NonCancellable. CodeEditorView.save is not cancellation-atomic: cut between writeTo and markUnmodified(), or before the tab loses its asterisk, it leaves the bytes on disk with the buffer still flagged dirty - so saveFile could report false for a file that was written. Scoped per file inside saveEditorInternal rather than at the call site, so every entry point gets it and a multi-file save can still stop between files. The changelog said an older IDE "silently returns false". It does not: the default body keeps the addition compatible for implementers of the interface, but a caller compiled against 26.36 emits INVOKEINTERFACE against a host interface that has no saveFile, so the call site fails with NoSuchMethodError. Corrected in both the changelog and the plugin-api KDoc. Drops the GPL header from the two new test files, whose URL goes off-device. Matches the majority of app test files (26 of 43) and every plugin-manager test; the 2983 existing files that carry it are left alone.

Re-review after the QA fixes. Confirmed genuinely fixed: the counter moved into the retained EditorViewModel, the coerceAtLeast(0) floor, the view-instead-of-index handoff (both index schemes verified to be the same one, so re-resolving via findIndexOfEditorByFile is sound), the changelog entry, the plain var over AtomicInteger, beginFileSave() inside the try, and the Dispatchers.IO hops. withContext's ensureActive() semantics check out: beginFileSave cannot throw before incrementing, so the counter is balanced.
7 findings below, no criticals: 4 MEDIUM, 3 MINOR. The mediums cluster on one theme - the false return still does not mean what the two KDocs say it means, and the cancellation path still drops post-write work.

A save's answer is now a FileSaveOutcome - WRITTEN, ALREADY_CLEAN, NOT_OPEN or FAILED - recorded in a holder the caller passes in, rather than a bare Boolean returned through a scope that may already be cancelled. Three of the review findings were the same shape: a Boolean cannot say what happened. The bound in EditorProviderImpl.saveFile no longer turns a completed write into false. NonCancellable made the write atomic, but the resume still threw TimeoutCancellationException into withTimeoutOrNull, which yielded null. The outcome is set from inside the NonCancellable section, so it survives the cancellation and is what saveFile returns; the log line no longer claims to have aborted something that ran to completion. CodeEditorView.save's "nothing to do" false is no longer reported as a failed write. Past the pre-check, an unmodified buffer means a concurrent UI save-all wrote this same content and marked it clean, so that is ALREADY_CLEAN, not FAILED. And an IllegalStateException from save() can only be the binding getter's "Binding has been destroyed", raised by markUnmodified()/notifySaved() after the write - the write section itself uses the nullable _binding? - so a tab closed mid-save loses its bookkeeping, not its bytes. Every claim that content reached disk is checked against disk before it is returned. The post-write follow-ups moved inside NonCancellable. isSyncNeeded and generateSources() sat outside it, and the file.exists() check above them was itself a suspension point, so a cancellation landing after the write dropped the sync prompt for a Gradle script already on disk, and the R fields for a layout's new resources. IdeEditorServiceImpl.saveFile wraps ensureFileAccessible in Dispatchers.IO - it stats the filesystem through the host pathValidator or canonicalPath, one frame above the hop added to keep this off the main thread. areFilesModified is computed in the block that writes it. Sampling it in an earlier Main.immediate hop and consuming it in a later queued one let an edit made in another tab meanwhile be clobbered by a stale false, greying out Save over a dirty buffer. Also drops a queue round-trip from the NonCancellable section. Reverts the module-wide isReturnDefaultValues in plugin-manager. It was there for two Log.d calls; those now go through slf4j, as the module's other service impls already do, so no android.jar stub is needed and the other four test classes keep failing loudly on unmocked Android calls. android.util.Log was IdeEditorServiceImpl's only android import. Drops the claim that the default body keeps saveFile compatible for implementers. plugin-api sets no -Xjvm-default, so it compiles to an abstract interface method plus a DefaultImpls static - both in the ABI dump - and a previously-compiled implementer would get AbstractMethodError, not the default.
Description

saveCurrentFile()API resolves its target based on UI tab focus and launches asynchronously, leading to desynchronization since it returnstruebefore persistence actually occurs. This PR introduces a new file-targetedIdeEditorService.saveFile(File)API that resolves the editor strictly by file, suspends until the write completes, and accurately returns the true on-disk outcome.Details
