Task 0 (#689 worktree wipe): F1-F5 committed on task/689 (663ffa5, 11c2ce3) with tests. fmt, flare-git-core (246), work_item_pipeline (116), and wipe-guard tests pass. Open: clippy dead-code error on fast_stall in src/agent_launch_tests.rs (not touched by this branch); full workspace tests and the fails-on-master check for the regression test were not run.


Opened by claude-code on flared:c997d745ae66 for item #689 via agentflare.

Summary by CodeRabbit

  • New Features
    • Added safeguards against accidentally deleting or publishing large numbers of tracked files. Unstaged deletions can be restored, and explicit force or an allow-mass-deletion label can permit completion.
    • Worktree cleanup now moves directories aside before deletion, helping preserve data if removal fails.
  • Bug Fixes
    • Git commands now use the repository associated with their working directory, avoiding interference from inherited Git settings.
    • Worktrees with live claims or intact repository data are protected from being cleared.
    • Checkpointing and publishing now stop when mass deletions cannot be verified or are not allowed.

📝 Walkthrough

Walkthrough

The changes filter Git repository-location variables, protect worktree reclamation, detect mass deletions, and add guards to item completion, pushes, and implementer checkpoints.

Changes

Worktree mass-deletion safeguards

Layer / File(s) Summary
Git environment and safe worktree reclamation
crates/flare-git-core/src/shell.rs, crates/flare-git-core/src/snapshot.rs, crates/flare-git-core/src/worktree.rs, crates/flare-git-core/src/worktree_orphans.rs, crates/flare-git-core/src/worktree_tests.rs, crates/flare-git-core/src/worktree_wipe_tests.rs, src/mcp_server/item.rs, src/cli/work.rs
Git child commands clear repository-location variables. Worktree reclamation checks pointer integrity and live claims before clearing a directory. Removal parks directories before deletion. A failed reclamation that reports that nothing was deleted preserves the claim.
Mass-deletion detection and worktree restoration
crates/flare-git-core/src/worktree_wipe_guard.rs, crates/flare-git-core/src/worktree.rs, crates/flare-git-core/src/worktree_wipe_tests.rs
Worktree and branch checks identify deletions above the configured thresholds. During reclamation, the guard restores mass-deleted files when the deletions are unstaged and no other changes are present.
Item completion and push guards
src/worktree/mod.rs, src/mcp_server/item.rs, src/mcp_server/item_force.rs, src/mcp_server/tests/item_wipe_guard_tests.rs, src/mcp_server/tests/mod.rs
Item completion checks uncommitted changes before auto-commit and checks branch deletions before pushing. Force or the allow-mass-deletion label can waive the guard.
Implementer checkpoint guard
src/work_item_pipeline.rs, src/work_item_pipeline/tests.rs
Implementer checkpoints check for mass deletions unless the allowance is set. The SDD loop fails the step when checkpointing returns an error.

Merge Risk: ⚪ Minimal · up to 6256c

The change adds safeguards so a claimed item's worktree is no longer wiped and the wipe is not committed or pushed. Pushes that delete many tracked files are refused unless explicitly waived, and every waiver is recorded with its reason. The previously raised concerns appear addressed, and no blocking issues remain.

Explanation

The description provides limited test status and known gaps, but it does not follow the required template. It omits the Summary, Test plan checklist, and Notes for reviewers sections, including risk areas and backwards compatibility.

Resolution

Rewrite the description using the repository template. Add a Summary that explains the changes and motivation, complete the Test plan checkboxes for all required commands, and add Notes for reviewers covering risk areas and backwards compatibility. Preserve the reported clippy failure and unrun tests.

270-275: 🩺 Stability & Availability | 🔵 Trivial | 💤 Low value

The trash sweep can delete another call's parked copy while that call is still deleting it.

After a successful rename, this code calls remove_dir_all on every entry in the shared .worktrees/.trash. Separate job processes can reclaim different worktrees at the same time. If that happens, one process's sweep can run while another process is still inside delete_parked on its own parked copy. Both processes then delete the same tree. On Windows, this can produce errors and log noise. On all platforms, it removes the guarantee that a leftover copy belongs to an earlier, finished call. Data is not lost, because the source path was already renamed away. Restrict the sweep to entries older than a grace period, or skip entries whose names match an in-flight stamp.

270 - 275:
Update the `.trash` sweep around `delete_parked` to skip entries that may belong
to an in-flight deletion, using an age-based grace period or by excluding names
matching an in-flight stamp. Only call `remove_dir_all` for entries confirmed to
be from an earlier, finished call.

Inline comments:
Review comments at @crates/flare-git-core/src/worktree_wipe_guard.rs:
- Around line 105-108: Update branch_mass_deletion to handle merge-base failure
explicitly instead of treating it as a valid missing fork. Fail closed so the
branch’s history is not reduced to checking only its tip commit when merge-base
cannot determine the common ancestor.

Review comments at @src/mcp_server/item_force.rs:
- Line 158: Update the forced mass-deletion flow around `force_takeover` so it
records the supplied `force_reason` before committing or pushing even when the
caller already owns the claim and `force_takeover` returns `Ok(None)`. Preserve
the existing takeover audit and avoid posting a duplicate when takeover already
recorded it.

Review comments at @src/mcp_server/item.rs:
- Line 1197: Update the error rollback branch that calls roll_back_claim to
retain and pass before_claim’s held-before flag instead of discarding it. Update
roll_back_claim to restore the prior item state and assignee, releasing the
owner’s claim only when the request acquired it.

Review comments at @src/mcp_server/tests/item_wipe_guard_tests.rs:
- Line 8: Update the Git command creation in the temporary-repository tests to
use the repository’s sanitized Git helper, or explicitly remove GIT_DIR,
GIT_WORK_TREE, and GIT_INDEX_FILE from each child command. Ensure mutating add,
commit, and restore commands target only the temporary worktree, regardless of
inherited environment variables.
