feat(tools): publish apply_patch through the guard (U6, #1375) by easonLiangWorldedtech · Pull Request #1915 · Zoo-Code-Org/Zoo-Code

easonLiangWorldedtech · 2026-10-05T12:10:38Z

What it does

Split unit U6 of #1833, under the plan issued on the tracking issue (5993969784 / 5994039786 / 5994053776). Merge order is U1→U2→U3→U4→U5→U6→U7→U8→U9, so the base for review purposes is U5 (#1914).

One gate scope: the apply_patch tool publishes through the S4 guard, a move carries the source's completeness to its destination instead of claiming completeness for lines the model never read, and a partial-source move onto an observed destination is rejected before any state changes.

Also in this head (205c82592): DiffViewProvider.saveDirectly now rolls back the parent directories it created when the guarded publish is refused (see the Lifecycle note below).

Superseded umbrella PR: feat(tools): track read completeness and guard the diff-view save path (S4b, #1375) #1833 (closed; its content is being landed as units U1–U9).
Tracking issue for the split plan: easonLiangWorldedtech/Zoo-Code#41.

Implementation details

Content source of record: kind: commit, base 7c291bb08 → head 6768ccfaf, replayed onto the current main tip so the branch carries nothing main already has.
Budget (own delta, not the stacked view): 691 a+d / 105 changed executable lines — inside both the size and mutation caps. The GitHub diff also shows the unmerged base units; the numbers above are this unit alone.
apply_patch publishes via guardedWrite, so an unobserved overwrite and a stale version token are rejected with the read-first / re-read-then-retry remediation instead of clobbering the file.
A move re-targets the source's observation onto the destination: the destination inherits the source's complete flag, so a slice/range/truncated/indentation-block source never authorizes a full-file replacement at the new path.
A partial-source move onto a destination that was already observed completely is rejected before any file or registry state is touched.
saveDirectly captures the list createDirectoriesForFile returns and, if the guard rejects, removes those directories innermost-first with rmdir (which refuses a directory another writer populated, so the loop stops at the first failure) and rethrows the original write error.

How to test

# from the repository root, with dependencies installed (pnpm install)
pnpm --dir src exec vitest run --globals core/tools/__tests__/applyPatchTool.guardedWrite.spec.ts
pnpm --dir src exec vitest run --globals integrations/editor/__tests__/DiffViewProvider.spec.ts
pnpm --dir src exec tsc --noEmit
pnpm --dir src exec eslint --prune-suppressions --max-warnings=0 <changed files>

Environment: Node 22+, pnpm 10, Linux/macOS/Windows CI runners (the guard's platform-specific branches are exercised through the injected platform option, not a real Windows host).

Local verification at 205c82592: integrations + core/tools + activate lanes 1340 passed / 17 skipped across 60 files; tsc --noEmit clean; eslint clean on both changed files with no suppression-count increase. The directory-rollback test is a real pin — with the DiffViewProvider.ts change stashed it fails.

Pre-submission checklist

One gate scope; no unrelated changes.
Branch contains the latest upstream/main.
Unit delta inside the size and mutation caps; split plan already issued on [BUG] GPT-5.5 Codex uses incorrect context window #41.
Tests added at the lowest layer that would have failed (tool-level guard tests, provider-level rollback test).
tsc --noEmit clean; eslint clean; src/eslint-suppressions.json counts unchanged.
No .changeset files and no CHANGELOG.md edits (managed by maintainers).
No new user setting, so the persisted-setting round-trip checklist does not apply.

Documentation impact

None. No user-facing setting, command, or documented behavior string changes; the guard's remediation text is already documented in the U4/U5 units.

Additional notes

The mutation-diff advisory gate reports 894 changed executable lines against the 500 cap for this branch's stacked view; the unit's own delta is 105. The remedy is maintainer-side (cap or per-unit run), tracked on [BUG] GPT-5.5 Codex uses incorrect context window #41 (6024918865 / 6025443324); it is not a reason to split this unit further.

📝 Summary

Summary by CodeRabbit

New Features
- File changes are checked against versions observed during reads, helping prevent accidental overwrites when files have changed.
- Partial reads are distinguished from complete reads, and edits requiring the full file are blocked when only part was observed.
- File writes use safer staging and publishing, preserve existing permissions, and support backups.
- JSON writes can be confined to a specified directory.
- Read results report clipped lines separately from omitted lines.
Bug Fixes
- Writes through symlinks and failed writes receive improved safeguards, including cleanup that avoids altering existing content.

Walkthrough

The change adds per-task file observations and guarded publishing for reads, patches, diffs, and editor saves. It also adds staged text publishing and updates JSON writes to use resolved targets, optional path confinement, and the shared text-writing implementation.

Changes

Observed reads and guarded writes

Layer / File(s)	Summary
File observations and read completeness `src/core/task/*`, `src/core/tools/ReadFileTool.ts`, `src/core/tools/ApplyDiffTool.ts`, `src/core/tools/ApplyPatchTool.ts`, `src/integrations/misc/indentation-reader.ts`, associated tests	Tasks now own an `ObservationRegistry` for file versions and read completeness. Stable reads record observations; completeness reflects truncation, clipping, read ranges, and lossy decoding.
Guard checks and serialized publication `src/core/tools/guardedWrite.ts`, `src/core/tools/__tests__/guardedWrite.spec.ts`	The new guarded writer supports create, update, and edit checks. It serializes writes by path, checks versions under a resolved-path lock, and refreshes observations after successful publication.
Patch, diff, and editor write paths `src/core/tools/ApplyPatchTool.ts`, `src/core/tools/ApplyDiffTool.ts`, `src/integrations/editor/DiffViewProvider.ts`, associated tests	Patch and diff writes pass explicit write kinds. `DiffViewProvider` records preview observations, uses guarded publishing, and handles rejected writes and placeholder cleanup.

Atomic text and JSON publishing

Layer / File(s)	Summary
Text staging, commit, and cleanup `src/services/file-safety/safeWriteText.ts`, `src/services/file-safety/__tests__/*`	The new `safeWriteText` implementation resolves targets, validates staging paths, stages and flushes content, and handles backups, commit, metadata, and cleanup.
Confined JSON writes and resolved-target locking `src/utils/safeWriteJson.ts`, `src/utils/__tests__/safeWriteJson*`	`safeWriteJson` adds optional path confinement and uses resolved targets and lock keys. It stages JSON beside the target and delegates backup and commit operations to `safeWriteText`.

Merge Risk: 🔵 Low · up to 205c8

Guarded file publishing is generally sound. Two edge cases remain. Concurrent first writes under a symlinked missing parent can take different locks. Accepting or reverting a diff in one task can close another task's diff tab. The PR is mergeable with follow-up awareness.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 5a0dd

The change improves protection against stale and partial-file overwrites. However, replacing an existing file can weaken Windows access restrictions when permission restoration fails. Some move operations also retain their existing non-atomic behavior.

Retained concerns

Medium · security · inferred: Existing-file direct tool writes now replace the file instead of updating it in place. On Windows, publication precedes DACL restoration, and failures saving or restoring the original DACL are swallowed. Where the replacement has broader permissions than the original, an approved content edit can therefore expose the file to additional readers or writers, temporarily or persistently. Successful restoration mitigates the persistent case but does not make access-control preservation a publication precondition.

Security review details

Security Blast Radius

inferred — The inspected exposure is host filesystem content published with the extension process's existing authority. The Windows concern affects individual rewritten files whose original DACL is more restrictive than the replacement's permissions; additional principals may gain read or write access without receiving elevated process privileges.

Security Findings and Attack Paths

inferred — A legitimate approved write to a Windows file with a restrictive explicit DACL reaches replacement publication. If saving or restoring that DACL fails, the write still succeeds. A principal permitted by the replacement's broader permissions can then read or modify content previously restricted by the original DACL. The failure behavior is demonstrated by mocked tests; deployment-specific permission widening was not reproduced.

Trust Boundaries and Controls

observed — Observation authority is task-scoped and separates content completeness from filesystem version identity. The guard checks cancellation after queueing and under the lock, rejects stale versions, and retains partial completeness after targeted edits.
observed — Publication deliberately follows existing symlink referents and rejects dangling links. Move containment is lexical, while ignore matching resolves referents but allows outside-directory paths or errors. Tool writes already followed symlinks at the base, so this is not established as a new tool escape. JSON writes now follow referents instead of replacing links; production-path attacker control remains unresolved.

Resilience and Maintainability Implications

observed — Rejected editor saves use discard-only recovery rather than writing the original preview back over newer disk content. Placeholder removal checks its captured version under the shared lock, and overlapping teardown operations are serialized. Successful publication clears an unchanged dirty buffer by reloading from disk rather than performing another unguarded save.
observed — Move destination publication and source deletion remain separate operations. Source deletion has no version check and its failure is logged rather than propagated; the non-focus move branch still uses raw destination writes. Comparison with the base confirms these lifecycle limitations predate the PR, so they are not retained as newly introduced concerns.

Hardening Proposals

proposed — Make preservation of an existing Windows DACL a publication precondition: prepare and verify equivalent restrictions on the replacement before making it visible, and reject the write when preservation cannot be established.
proposed — Document the resolved-target authorization policy for tool and persistence writes, then test outside-workspace referents and referent changes. Treat source-version-protected move cleanup and consistent guarding across execution modes as follow-up work for the existing lifecycle gaps.

Full details: Regression Evidence

Explanation

ApplyDiffTool added two stat-failure branches without focused coverage. At lines 76 and 78, pre-read and post-read fs.stat failures are caught and treated as an unobserved read, while the diff operation continues. applyDiffTool.guardedWrite.spec.ts covers stable stats, mismatched stats, matching observations, and stale observations (lines 221-292), but it has no test for either stat rejection. The existing ReadFileTool tests do not cover this separate ApplyDiffTool path.

Resolution

Add focused ApplyDiffTool tests for pre-read fs.stat rejection and post-read fs.stat rejection. Assert that the diff read still proceeds without a tool failure, the observation registry remains unchanged, and the save follows the expected fail-closed guard behavior.

Full details: Security Boundaries

Explanation

The new safeWriteJson(..., { confineTo }) path has a symlink TOCTOU that bypasses its allowlist. safeWriteJson checks the canonical target under the lock at src/utils/safeWriteJson.ts:202-205, then stages and calls safeWriteText at line 246. safeWriteText resolves the path again at src/services/file-safety/safeWriteText.ts:231-237 and renames to that result at line 480. If /workspace/link initially points inside the confined directory and a concurrent local process changes it to /outside after the check, the write is committed to /outside/file without another confinement check. This is a concrete changed path that can overwrite a secret or PII file outside the approved directory.

Resolution

Make confinement and publication use one stable, canonical target. Do not re-resolve a mutable symlink path after the confinement check. Anchor directory creation, staging, and the final rename to an opened confined-directory handle with no-follow semantics, or otherwise use atomic no-follow filesystem operations. Pass the confinement requirement into the final publish primitive and revalidate the exact rename target as part of that primitive.

Full details: Lifecycle Resource Cleanup

Explanation

safeWriteText can leak newly created parent directories. The new implementation creates dirPath at lines 235-237, then validates a caller-supplied tempPath at lines 245-299. Invalid staging input throws before the cleanup try begins at line 306. For a new nested target with an out-of-directory or invalid staging path, the write rejects but leaves empty parent directories behind.

Resolution

Track which parent directories safeWriteText creates, and wrap directory creation plus staging validation in cleanup handling. On any pre-publish failure, remove only those directories that remain empty, from the innermost directory outward. Do not remove pre-existing or caller-owned directories.

…ve (U1, issue 1375) Split unit U1 of PR 1833. Three changes, each with a test that fails without it: - a caller-supplied staging path is checked for location and file type before anything is written, so an arbitrary path or a symlink cannot be published onto the target; - a failed parent-directory fsync on POSIX is reported as PostCommitDurabilityError instead of being swallowed, so a successful return never claims durability the filesystem did not grant; - the staged file and this write's own staging directory are released before RollbackFailureError is thrown. Focused coverage for resolveLockKey added: canonical parent directory, a dangling-link chain, and termination at the bounded depth on a two-link cycle.

…ishTarget (U1, issue 1375) The resolver may fall back to the given path only when lstat also reports the path as absent. An EACCES or EIO failure says nothing about whether the path is a link, so falling back would publish through a link we were not allowed to inspect. Focused tests added for both branches.

… type-sound compile failed at the unit head on three points: - RollbackFailureError needs a string backupPath, but the throw now happens after cleanup, so the `string | null` narrowing was lost. The failure is now held as { error, backupPath }. - The async lstat stand-in is built on the Stats prototype so it satisfies fsSync.Stats. - The realpath/readlink mocks are typed to the real signatures; the readlink mock answers once because only the link path is read. tsc clean, 50 tests pass, ESLint --max-warnings=0 clean, no suppression change.

📢 Thoughts on this report? Let us know!

The any usage this entry covered is gone in the rewritten file, so the count drops 4 -> 3. eslint --prune-suppressions --max-warnings=0 confirms it.

The read tools record the observed on-disk version through task.observationRegistry, but the field was only declared in a later unit, so at this head the call dereferences undefined and the mocked e2e run fails on the read_file smoke tests. The registry is introduced by this unit, so the field belongs here. tsc clean on this unit, 11 observationRegistry tests pass, ESLint --max-warnings=0 clean.

The two any usages this entry covered are gone in the rewritten spec, so the count drops 98 -> 96. eslint --prune-suppressions --max-warnings=0 confirms it.

…a copy - applyDiffTool.guardedWrite.spec: four `await tool.execute(...) as unknown as void` suffixes were double assertions that changed nothing; execute already returns Promise<void>, and the other tests in the same file await it plainly. - safeWriteJson: three comments still described the old backup contract (rename the target away, roll it back on failure). safeWriteText takes the backup as a COPY, never moves the target, and removes the copy on failure, so the comments now say that: the lock-key walk tolerates a dangling link because a create or a peer mid-staging can present one, Step 2 delegates backup + commit (not rollback), and a failed safeWriteText leaves the target holding the pre-write bytes. Local: 33 passed / 4 skipped across the two specs; eslint clean on both files.

Pushed 205c82592 and rewrote the description.

Lifecycle Resource Cleanup (Warning) — fixed. saveDirectly created the parent directories and threw away the list createDirectoriesForFile returns. When the guard rejects — a task cancelled while the write waited on the chain, a stale version, an unobserved overwrite — the error path resets the provider, but the provider never recorded those directories, so empty scaffolding stayed in the workspace for a write that never happened.

The list is now captured and removed innermost-first with rmdir when the publish fails, using the same discipline as the existing open()/discard cleanup: rmdir refuses a directory another writer populated in the meantime, so the loop stops at the first failure and nothing in use is deleted. The original write error is rethrown unchanged.

Test drives the real guard: an unobserved write into two freshly created directories rejects with the read-first remediation and both directories are removed in reverse order. Verified as a real pin — with the DiffViewProvider.ts change stashed the new test fails.

Description check (Warning) — fixed. The body now follows the repository template: related-issue links (epic #1375, superseded #1833, split plan on #41), implementation details, copy-pasteable test commands with environment, a completed pre-submission checklist, documentation impact, additional notes (including the mutation-diff stacked-view caveat) and the N/A screenshot/video and reviewer-contact sections.

Local: integrations + core/tools + activate lanes 1340 passed / 17 skipped across 60 files; tsc --noEmit clean; eslint clean on both files with no suppression-count increase.

Review comments at @src/core/tools/ApplyDiffTool.ts:
- Around line 76-97: Extract the stat-bracketed read and observation logic
around versionTokenOfStat in ApplyDiffTool.execute into one shared helper, then
reuse it across the read, diff, patch, and DiffViewProvider paths. Centralize
the prior-observation rule so a mismatched version remains stale rather than
being refreshed as partial, and return the read content with its stable token.

Review comments at @src/integrations/editor/DiffViewProvider.ts:
- Line 858: In DiffViewProvider’s revertChanges paths for new and existing
files, replace closeAllDiffViews with closeOwnDiffView(absolutePath) so
reverting closes only this provider’s diff view. Apply the same change to the
accept path in saveChanges, preserving the existing surrounding behavior.

Review comments at @src/services/file-safety/safeWriteText.ts:
- Around line 192-196: Update canonicalDirKey to resolve the nearest existing
ancestor and append the missing path components so its lock key remains stable
before and after parent directories are created. Fall back to a lexical path
only for ENOENT; propagate other realpath errors instead of silently producing a
different key.

Review comments at @src/utils/safeWriteJson.ts:
- Around line 259-263: Update the catch comment in the `safeWriteJson` flow to
reflect both outcomes: a failure before commit leaves the target unchanged,
while a `PostCommitDurabilityError` occurs after the new content is published.
Describe backup cleanup as best-effort within `safeWriteText`, and retain the
`.new` file cleanup explanation without implying that a failed write always
leaves the target unchanged.

Learning: In Zoo-Code's src/services/file-safety/safeWriteText.ts, staging/target identity comparisons must use filesystem stats with { bigint: true }. NTFS/ReFS inode and device identifiers can exceed Number.MAX_SAFE_INTEGER. Number rounding can reject a valid staging file or fail to detect a staging file that aliases the target.

… one lock key per file - DiffViewProvider: the accept path in saveChanges and both revertChanges paths still called closeAllDiffViews(), which closes EVERY clean diff tab in the workbench. With Task.run() letting TaskScheduler run tasks concurrently, one task accepting or denying an edit tore down another task's diff view while that task's provider still held its activation listener and deferred scroll timer against a tab that was gone. All three now use closeOwnDiffView(absolutePath), matching reset() and the rejected-save cleanup this unit already introduced. - safeWriteText canonicalDirKey: realpath(dirPath).catch(() => dirPath) kept every alias component while the parent directory did not exist yet, so the same new file got one lock key before its parent existed and another one after - two writers, two locks. The key now walks to the nearest EXISTING ancestor and re-appends the missing components, which is the rule the docstring already promised. - safeWriteJson: the catch comment claimed the commit rename is safeWriteText's last step, so a failed write leaves the pre-write bytes. A PostCommitDurabilityError is raised AFTER the rename (parent-directory fsync), where the target already holds the NEW bytes; a restore or retry written against that comment would overwrite published content. The comment now names that exception. Tests: revertChanges closes only its own tab (and does not call closeAllDiffViews); resolveLockKey stays canonical while the parent directory is missing. The saveChanges accept assertion was updated to closeOwnDiffView. Pins: restoring closeAllDiffViews in revertChanges fails the new tab test; restoring the lexical parent fallback fails the lock-key test. Not changed: the apply_diff vs apply_patch prior-observation rule. Both paths fail closed (applyPatchTool.execute.spec 'does not carry completeness across a version the model never read' asserts the full-file replacement is rejected), and the six read+observe copies live on four independent unit branches, so a shared helper cannot land in this unit. Local: integrations/editor + services/file-safety + utils + core/tools = 1609 passed / 10 skipped; tsc --noEmit 0; eslint 0 err / 0 warn on all five touched files.

@coderabbitai full review

Re-requested at head 3f5c99ee2: three of the four findings from the review at 205c82592 are fixed (diff-view teardown scope, lock-key stability, stale catch comment); the read+observe consolidation is answered inline with the verification and a follow-up plan on #41. CI at the previous head was 7/7 green.

The any usage this entry covered is gone in the rewritten file, so the count drops 4 -> 3. eslint --prune-suppressions --max-warnings=0 confirms it.
