Four copies of the same loop ran `git remote` and then a serial
`git remote get-url <name>` per remote to answer "which remote has this
URL". On a repo with 58 remotes that is 59 subprocesses -- measured at
1083 ms -- for one question, and worktree create asks it several times.
`git remote -v` answers for every remote from one child, reporting the
same insteadOf-expanded first fetch URL `get-url` prints.
The batched `cat-file --batch-check` branch-conflict probe decides from
stdout, but its WSL route was unfenced, so a login-shell fallback printed
the distro banner onto the stream it parses. That broke the
one-line-per-ref contract, made every batch undecided, and fell straight
back to one `show-ref` per remote -- the cost the batch exists to remove.
Measured at 58 remotes / 4346 branches, spawns and wall time:
push-target remote scan 59 -> 1 (1083 ms -> 8 ms)
branch-conflict probe 60 -> 3 (984 ms -> 43 ms)
configured push target 123 -> 6 (2707 ms -> 157 ms)
* fix(git): narrow fork-remote fetch refspecs to tracked branches
git remote add with no -t writes the wide +refs/heads/*:refs/remotes/<name>/*
refspec, so any later plain `git fetch` (user, agent, or Orca's own Fetch
action) re-imports a fork's entire branch set and its tags -- one real
machine had ~50 leaked/wide fork remotes producing 59,716 remote-tracking
refs. Mint and reuse now pin -t <branch> --no-tags; a rate-limited sweep
narrows and cleans up remotes minted before this fix; gitFetch self-heals
when a narrowed remote's tracked branch is later deleted upstream.
Refs #17828
* fix(git): soften narrow fork-remote refspec against deleted upstream branches
A bare `git fetch` in a worktree checked out on a fork-PR branch resolves to
the pr-* remote via branch.<name>.remote -- not origin -- making it the
dominant fetch shape in Orca's terminal-centric, agent-driven usage. The
previous literal-refspec design hard-failed that fetch ("couldn't find
remote ref") the moment the tracked branch was deleted/renamed upstream,
which is not the narrow edge case it was first described as.
Switch to a trailing-`*`-suffixed refspec source/destination
(refs/heads/<branch>*:refs/remotes/<name>/<branch>*). Verified against real
git: this restores wildcard zero-match tolerance (silent no-op instead of a
hard failure) and lets plain `git fetch --prune` reclaim the stale ref once
the branch disappears, at the cost of also matching sibling branches that
share the literal name as a prefix -- a materially smaller widening than the
original unbounded-import bug.
Also close a race with #17842's orphaned-pr-remote reconciliation sweep:
both sweeps read the same worktree-metadata store to pick candidate remotes,
so reconciliation can `remote remove` a remote this migration is
concurrently narrowing. `ensureRemoteTracksBranchNarrowly`'s plain `config
--add` would silently resurrect a url-less config section in that case;
re-check `remote.<name>.url` (via the new `remoteHasUrl`, plumbing rather
than porcelain `remote get-url`, which falls back to echoing the remote name
as a bogus URL) after the narrowing writes and remove the section if it's
gone.
* fix(git): update stale fork-remote mint assertions for -t/--no-tags and wildcard-suffix refspec
Four test files still asserted the pre-#17828 remote-add shape or the
literal (non-wildcard-suffixed) fetch refspec from before the
deleted-upstream-branch softening commit, so CI went red on that HEAD:
- worktree-push-target-refspec-real-git.test.ts: the migration fixture
asserted a hardcoded tracked-ref count before narrowing. Under git
>= 2.44, `followRemoteHEAD` auto-creates a `refs/remotes/<name>/HEAD`
symref on the first fetch matching the full wildcard refspec, adding
one untracked ref. Made the count/assertions robust to that ref's
presence instead of hand-tuning the constant per git version.
- worktrees-wsl-runtime-routing.test.ts: assertions predated both the
`-t <branch> --no-tags` mint change and the wildcard-suffix refspec
change; updated to the full, correct call sequence and confirmed the
WSL routing options (cwd, wslDistro) are threaded to every call.
- worktrees-create-metadata-persistence.test.ts and
orca-runtime-tests/worktree-removal-and-reconciliation.spec.ts: same
class of staleness, found via CI job log cross-referencing rather
than being explicitly flagged.
Verified out of scope: the SSH fork-remote mint path
(prepareWorktreePushTargetSsh) is untouched by this PR -- it never
persists a `remote.<name>.fetch` refspec at all, using
provider.fetchRemoteTrackingRef for a targeted per-branch fetch
instead -- so worktrees-ssh-fork-push-target-remote.test.ts needed no
change.
* fix(git): migrate pr-* remotes with zero worktree-metadata trace too
The migration sweep's candidate discovery was purely metadata-driven
(store.getAllWorktreeMeta()), so a pr-* remote whose every referencing
worktree was removed outside preserve-on-delete (metadata purged, not
just the worktree) was permanently invisible to it and stayed on the
wide default forever.
Field data from a manual migration run against a real user's repo (31
pr-* remotes, 34,637 tracking refs, only 18 actually needed) found
exactly this: 15 of 31 remotes had no branch pinning them at all.
Widen discovery to every pr-* remote git reports on disk, in addition
to metadata-derived candidates. For a remote with no branch provenance
from either metadata or surviving branch.*.remote/.pushRemote config,
there's nothing to narrow *to* -- clear its fetch refspec entirely
instead (stays pushable, imports nothing on a plain fetch), gated on
it still carrying the untouched stock wide default so a user's own
custom pr-*-named remote isn't touched. Removing the remote outright
stays #17842's job.
Adds clearForkRemoteFetchRefspec (fork-remote-refspec.ts), 3 new
mocked-exec tests, and a real-git integration test proving a
subsequent plain `git fetch` on the cleared remote imports nothing.
* Fix rebase race by fetching to private ref before rebasing
`git pull --rebase` is vulnerable to concurrent fetches modifying remote-tracking refs during execution. Fetch to a temporary private ref (refs/orca/rebase/*) first, then rebase from that stable ref to avoid the race condition.
* Fix rebase race by fetching to private ref with timeout
Concurrent fetches can interfere with remote-tracking refs between
fetch and rebase. Use a unique private ref and 60-second timeout to
isolate each rebase operation and prevent hangs on stalled remotes.
Extract gitPullRebaseFromBase to a dedicated module.
* fix rebase race by fetching to private ref with timeouts
Concurrent fetches can replace FETCH_HEAD and remote-tracking refs between
fetch and rebase, causing the rebase to fail. Fetch to a temporary private
ref instead, use --no-write-fetch-head when available (Git 2.29+), and
serialize FETCH_HEAD access for older versions. Add process termination
barriers to ensure proper cleanup and extend timeouts for SSH operations.
* Fix rebase race by fetching to both private and tracking refs
Concurrent fetches between source and rebase can replace remote-tracking refs,
causing rebases to use stale bases. Now fetch to both a private ref and the
remote-tracking ref simultaneously, ensuring the tracking ref stays current.
Also improves process termination for WSL guests with process-group tracking,
fixes process-tree termination timeouts on POSIX, and serializes FETCH_HEAD
operations for linked worktrees through their shared Git directory.
* Add WSL setsid --wait probe and barrier termination timeout
Probe for `setsid --wait` support and fall back to unwrapped execution for BusyBox compatibility. Add a deadline for process termination barriers to prevent hanging when tree termination cannot be verified. Update tests for cross-platform compatibility.
* Add wsl-process-group-termination to WSL invocation allowlist
* Serialize per-worktree git mutations to fix rebase race
Introduce operation locking for each worktree to prevent concurrent
mutations (like rebase) from interfering with each other. Ensures
rebasing a linked worktree doesn't affect the source worktree state.
Add SIGKILL fallback if process termination barriers cannot verify
tree termination.
* Serialize pull and fastForward operations per-worktree
- Extract generic git operation lock to reuse locking pattern
- Refactor existing locks to use the generic implementation
- Apply per-worktree serialization to pull and fastForward to prevent races
* Route WSL group termination through runWslProcess
ce743a4fd0 silenced the wsl-invocation boundary guard by appending
wsl-process-group-termination.ts to the allowlist. That fixture only
grows when the scanner learns to see a spawn it was blind to, and only
shrinks for a migration -- this was new code on this branch, so the
entry was the boundary regressing rather than the guard getting honest.
Migrate the kill instead. terminate() now calls runWslProcess with the
script form (`<shell> -c <script> -- <args>`), which keeps the group id
in $1, so the payload is unchanged. The script is plain POSIX, so it
must not pin shell: 'bash'; it calls only builtins and coreutils on the
default PATH and reads no login environment, so loginPath is 'none'.
wrapGuestArgs() is untouched: its argv is spliced into git/runner.ts's
own wsl.exe invocation, which is a long-standing allowlist entry.
The unit test now mocks runWslProcess and asserts the spec shape --
distro, loginPath, the group id in args -- so a regression back to a raw
spawn fails here as well as at the boundary guard.
* Assert cleanup is defined before accessing properties
* Fall back to a merge when a divergent pull has no reconciliation strateg
- Git 2.27+ refuses `git pull` on divergent branches unless pull.rebase or
pull.ff is configured. Retry with `--no-rebase` (Git's historical default)
so pulls succeed out of the box on fresh hosts.
- Skip the fallback whenever the caller already specified a reconciliation
strategy (e.g. --ff-only, --rebase) so explicit policies still fail as
expected on divergence.
- Applied identically in the local git pull path and the relay/SSH git
handler so both surfaces behave the same way.
* Refactor divergent-pull merge fallback into shared helper
Extracts the retry-as-merge logic (duplicated between local git and
relay SSH pull paths) into `runPullWithDivergenceFallback` in
git-remote-error.ts, so both callers share one implementation and
test coverage.
* feat(source-control): add Fix push failure with AI for pre-push hooks
Detect pre-push hook failures separately from auth/transport errors so
push toasts and inline messages no longer suggest checking repo access.
Mirror the commit-failure recovery flow with a fixPushFailure action,
summary panel, details dialog, and agent launch recipe in Settings.

* Enable pushing to configured push targets for existing fork reviews
* Resolve push targets using branch.pushRemote, remote.pushDefault,
and URL-valued remotes normalized to matching named remotes.
* Support this push target resolution on both local and relay/SSH
git handlers to prevent drift in SSH worktrees.
* Offer "Push" instead of "Publish Branch" in the Source Control UI
when a linked review exists and a valid push target is available.
* Prevent pushing a feature branch's base branch (e.g. main) directly
to a fork via remote.pushDefault.
* Keep fork push target when contributor branch matches base branch name
Ensure that a fork push target is not incorrectly discarded when its
branch name matches the base branch name on another remote (for example,
targeting fork/main while the base is origin/main).
Previously, the matching logic only compared the branch leaf name, which
treated different remotes as identical and disabled the push target. We
now qualify the ref comparison with the remote name to differentiate them.
Detect when git push operations fail due to un-pushed or out-of-sync
submodules, and extract the specific submodule name to provide clear,
actionable guidance to the user.
Additionally, update the Source Control error UI to allow better text
wrapping and word-breaking for detailed error alerts.
- Resolve an effective upstream so legacy branches tracking origin/main use
origin/<branch> when that remote branch exists.
- Pull, sync, and ahead/behind status now operate on the same branch the UI
reports, including after non-fast-forward push rejections.
* Create PRs directly from Source Control
- Replace the modal flow with an inline PR composer in the sidebar
- Keep PR creation state and validation scoped per worktree
- Rename the recovery action to clarify it only pushes before creating PRs
* Clean up fork PR remotes after worktree deletion
- Track Orca-created push target remotes in worktree metadata
- Reuse ownership markers when later worktrees share the same fork remote
- Fetch only the selected PR base instead of every remote before drafting PRs
- Mirror local branch cleanup for SSH worktree deletion
* Stabilize pull request creation flow
- Keep PR actions and composer fields locked while generation or creation is in flight
- Refresh git status, branch comparison, and history after remote actions settle
- Disable push-only actions on diverged branches so users sync first
* Make PR context generation read-only
- Stop rebasing or probing HEAD before collecting PR draft context
- Allow git operations on known repo roots without refreshing worktree cache
