never recursively removed after point-in-time verification when moveDirectory
falls back after EPERM or EXDEV. Use an atomic ownership transfer before
cleanup; if unavailable, retain the source and report the destination as
complete, rather than deleting it or relying on a post-deletion check.

existence is recorded before writing spec.md. During rollback, pass that
recorded state to pruneEmptyDirs and remove only directories created by the
operation, preserving pre-existing capability directories and their permissions
or ACLs.

fs.rename of a non-leaf change directory fails with EPERM on Windows when a watcher holds a handle. The fallback required a staging rename of the same directory, so it never ran: specs were rolled back after printing success, and a newly created capability was left as an empty folder git cannot see. Copy from the original source when staging also fails with EPERM/EXDEV, and prune empty capability dirs on rollback. Closes Fission-AI#1895 AI-assisted (Grok)
Addresses both review findings on the copy fallback. The staging rename was what claimed the source before it was deleted. Falling back without it means copy-then-remove now runs against the live change directory, which the archive claim does not cover, and a recursive remove deletes whatever is there at that moment - including a file written after the final fingerprint, which never reached the destination. Cleanup now removes a named set: the entries listed after the last verification, deepest first. A later arrival is not in that set, so it is never deleted, and the rmdir of its parent fails with ENOTEMPTY, which the caller already reports as a retained destination. The move fails loudly rather than completing with data missing. Rollback of a created spec pruned the capability directory unconditionally, which also removed one the user already had, along with its mode and ACLs. The snapshot now records whether that parent existed, and only a directory this write created is pruned. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

- Line 1014: Update snapshot capture and rollback pruning around the
parentExisted field and pruneEmptyDirs call: record the deepest existing
ancestor of the target directory at or below mainSpecsDir, then use that
ancestor as the pruning boundary and avoid pruning when it is the target’s
direct parent. Add or reuse a helper such as deepestExistingAncestor, ensuring
pre-existing nested directories are never removed.

Thanks @kevin9327 — good catch on the staging gate never letting the copy fallback run. I rebased onto 1. The unstaged cleanup (the major one). The staging rename was what claimed the source before it got deleted. Falling back without it means copy-then-remove now runs against the live change directory, which the archive claim doesn't cover — and Rather than retain the source (which would leave the change looking both active and archived, defeating the fix), cleanup now removes a named set: the entries listed after the last verification, deepest first. A later arrival isn't in that set, so it's never deleted — and the 2. Rollback pruning. Proof. Two new tests, each mutation-tested — reverting the corresponding fix in isolation makes exactly that test fail:
One note: the CI approved and running. Ready for maintainer review. |
Both follow-ups from CodeRabbit's second pass, and both are right. The removal listing was taken after the final fingerprint, which left the window it was meant to close: a file arriving between the fingerprint and the listing landed in the set and was deleted, having never reached the destination. Listing before the verification makes the two orderings exhaustive - an arrival either changes the fingerprint and aborts the move, or is absent from the set and survives. The one case this cannot cover, an edit to an already-listed file, is now stated in the comment. `parentExisted` only described the target's direct parent, so a nested capability id whose intermediate directory already existed still lost it: the prune walked to the specs root. The snapshot now records the deepest pre-existing ancestor and passes it as the prune boundary, which pruneEmptyDirs never removes. That one mechanism covers the flat case too.

Second CodeRabbit pass found two more, and both were right — pushed. Listing ordering. I had taken the removal listing after the final fingerprint, which left open exactly the window it was meant to close: a file arriving between the fingerprint and the listing landed in the set and got deleted, having never reached the destination. Listing before the verification makes the two orderings exhaustive — an arrival either changes the fingerprint and aborts the move, or is absent from the set and survives to trip Nested prune boundary.

Summary
openspec archiveon Windows can fail withEPERMrenaming the change directory (a watcher holds a handle on a directory that still has children). The copy fallback was gated on a staging rename of that same directory, so it never ran. Specs were then rolled back afterSpecs updated successfully, and a newly created capability was left as an empty directory git cannot see.This copies from the original source when dest rename and staging rename fail with
EPERM/EXDEV. Fingerprints still abort if the tree changes mid-copy. A staging failure that is notEPERM/EXDEVstill leaves the source untouched. Rollback of a created spec now also prunes the empty capability directory.Closes #1895
