* 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
#14397 split `shared/types.ts` into 46 per-domain modules but kept the path as
a re-export barrel so the import sites did not have to change. This removes
the barrel: every consumer now imports from the module that actually declares
the type, and `src/shared/types.ts` is deleted.
Barrels hide where a type lives, make every consumer look like it depends on
the whole domain, and let an unrelated edit invalidate a module that ~2,000
files transitively import.
2,323 import declarations across 2,321 files. Rewritten mechanically: each
specifier was resolved to an absolute path via the TypeScript AST and
recomputed, rather than string-substituted, so alias forms (`@/../../shared/
types`) and per-specifier `type` modifiers survive.
Four cases the mechanical pass had to handle, each found by a gate rather than
by reading the diff:
- Modules inside `src/shared` import the barrel as `./types`, not
`shared/types`. A pre-filter on the latter string skipped 176 of them and
left imports dangling at a deleted file, which surfaced as confusing
`Property 'x' is optional in type 'Repo' but required in Pick<Repo, ...>`
errors rather than "module not found".
- The barrel RENAMED one type on the way through
(`WorkspaceSource as WorkspaceCreateTelemetrySource`), so the original name
in the owning module has to be re-aliased at each consumer.
- Three test files put `;(globalThis as ...)` on the line after the import.
TypeScript parses that `;` as the import statement's terminator, so
replacing through `statement.getEnd()` deletes it and breaks ASI. The
rewrite now stops at the module specifier.
- A file that already imported directly from a module got a SECOND import
from it, because the barrel re-exported those same names — which trips
`import/no-duplicates` under `--deny-warnings`. A post-pass merges
declarations sharing a specifier and type-only-ness; the `import type` plus
`import` pair from one module is left alone, since that form is allowed.
Splitting one barrel import into several genuinely adds lines, which pushed
`terminal-layout-pty-ownership.ts` to 301 counted lines: its 107-character
import must wrap, and neither local type collapses onto one line (101 and 116
characters). Rather than contort a type declaration to fit a line budget,
`collectLeafIds` and `pruneLeaves` move to `terminal-pane-layout-tree.ts` —
they are pure structural operations on the layout tree and independent of PTY
ownership. `visible-worktrees.ts` similarly loses its own mini-barrel
re-export of `isDefaultBranchWorkspace`, with the four real consumers
repointed at the declaring module. No `max-lines` bypass added.
Verified: cold `tsc --noEmit` green on node, cli, and web (buildinfo deleted
first — these projects are `composite: true` and reuse stale caches); the full
`pnpm lint` green, not just bare oxlint — the narrower local check is what let
the duplicate imports reach CI; max-lines ratchet OK at 344.
* 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.
* 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.
- 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
