fix(write-to-file): address partial filesystem error review - #1066
easonLiangWorldedtech wants to merge 40 commits into
Conversation
…oo-Code-Org#703) - Remove unguarded createDirectoriesForFile call from handlePartial; the call was a redundant optimization (execute() already creates dirs before open()) and its unguarded throw caused the partial-block advancement gate in presentAssistantMessage to be skipped, permanently stalling the agent loop - Move createDirectoriesForFile in execute() inside the try block so EROFS/ EACCES errors route through handleError with diffViewProvider.reset() cleanup and consecutive-mistake counting, rather than escaping unhandled - Add regression tests covering both failure paths
…_file filesystem failure When write_to_file hits a filesystem error (EROFS/EACCES) the streaming phase left the "Zoo wants to edit this file" spinner running, surfaced the same error twice (handlePartial + execute), and spawned a new partial tool message on every subsequent streaming delta. - Add Task.finalizePartialToolAsk() to finalize a partial tool ask without blocking on user input, dismissing the spinner. - handlePartial swallows streaming filesystem errors (after finalizing the spinner and resetting the diff view) so only the authoritative execute() error is reported, eliminating the duplicate error bubble. - Track partialStreamFailed so later streaming deltas short-circuit instead of re-attempting and spawning repeated partial tool messages. - Add regression tests for spinner finalization, single-error reporting, and no repeated partial messages.

📝 SummarySummary by CodeRabbit
WalkthroughThe change adds partial tool-ask finalization and per-task streamed-write state management. WriteToFileTool now handles streaming and execution failures with diff cleanup, and creates parent directories during execution. Failed-task cleanup clears the tool’s state before disposing the task.

111-125: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winMissing-param early returns bypass the new per-task cleanup and error-safe reset.
These two guard clauses return before the

resetDiffViewAfterWritewrapper, calling the rawtask.diffViewProvider.reset()instead — reintroducing the unguarded-reset risk fixed elsewhere in this PR.If a prior partial delta already registered abort cleanup / seeded path-stabilization state for this task, a subsequent malformed block (missing
path/content) leaves that state stale for the next write_to_file call in the same task.🛠️ Proposed fix

Task.dispose() removes every listener, so a task disposed without an abort first (ClineProvider.cleanupFailedHistoryTask()) never runs the TaskAborted cleanup and the WriteToFileTool singleton keeps that task and its diff-view provider. The tool now exposes clearTaskState() and the direct disposal path calls it while the task is still present. The provider-shutdown path already aborts before disposal and is unchanged. Regression test asserts the order: the entry is gone before dispose() runs.

Update ??merged with upstream/main (2026-09-16)
Merged
upstream/main(99025b1fb) into this branch to resolve the merge conflicts. The PR's own delta against current main is unchanged: thewrite_to_file/ task-persistence fixes and the regression tests described above.Addressed the two remaining CodeRabbit findings (final commit
3d23d9d86):Task.spec.ts: the deletion-dependentfinalizePartialToolAsktest now restores the shared task directory (and theupdateClineMessagespy) in afinallyblock, so a rejecting operation or a failed assertion cannot leave sibling tests without their real persistence directory.writeToFileTool.spec.ts: both missing-parameter tests now prove the cleanup branchawaitsrevertChanges()beforereset()??therevertChangesmock awaits a deferred promise,reset()is asserted not to run while the revert is pending, and the final order is exactly["revert", "reset"].Updated the extension coverage population baseline in
src/scripts/verify-coverage-contract.mjs(30_229 to 30_299 instrumented lines, record count unchanged at 469) to account for this PR's added source lines on top of current main (ef7a941dc).n- Local evidence on the final head: mutation preflight on the unit delta ??extension **98 valid / 98 killed**, 0 timeout, 0 survived, 0 noCoverage (local gate green); the two touched spec files 172 passed / 5 skipped;tsc --noEmit` and ESLint clean with unchanged suppression counts.Re-merged upstream/main a second time (b9e2bda) after main advanced again: the only conflict was src/scripts/verify-coverage-contract.mjs, resolved by taking main’s version — main removed the absolute coverage-population baseline (updated by ef7a941) in favor of per-lane lcov validation and merged-report checks.
Fixed the two new CodeRabbit findings (a704b15): (1) BaseTool.handle() now exposes an onParameterParseFailure() teardown boundary for the native-args parse-failure path where execute() never runs - WriteToFileTool reports the captured streaming filesystem error under the writing-file context (instead of the incidental parse error) and clears the per-task state (streamFailed guard + abort listener); (2) the prevent-focus approval-denial branch now resets the provider state (editType/originalContent) so a later write re-checks the file system. Regression tests added for both; local mutation preflight on the final head: extension 116 valid / 116 killed, 0 survived, 0 noCoverage.
Addressed the follow-up CodeRabbit findings on the fix commits (7b6835f, 9d75b10): the execute() error path now runs the diff revert/reset cleanup in a finally around handleError (the production handleError awaits Task.say(), which rejects on an aborted task, so a rejected handleError can no longer skip the cleanup), and the regression tests prove the revert-then-reset sequencing with a deferred-promise pattern (reset() asserted not-called while the deferred revert is pending) plus the exact registered abort-listener reference.
Follow-up (8a5bf2d): the parse-failure teardown boundary now also restores the diff document (revert then reset). Streaming can open the diff view with unapproved partial content, and when the final block then fails to parse, execute() never runs, so its error cleanup never fires without this -- a user save could persist content the write never completed. Regression tests added for both the successful-streaming and streaming-failure parse paths.
