fix(git): share one failed-command error-text reader between local and the SSH relay (#18398)
* fix(git): share one error-text reader between the local and relay branch-delete fallbacks The relay and the desktop each carried their own `getErrorText`, and they had drifted: the relay read `message` + `stderr` + `stdout`, the desktop only `message` + `stderr`. A `git branch -d` refusal arriving on `stdout` therefore routed the SSH removal through prune-and-retry while the local removal gave up and preserved the branch. Against a real binary the two agree, because Git prints the refusal through `error()` on every supported version — verified on 2.25.1, 2.38.1, 2.49.1 and 2.55.0, none of which put a byte of it on stdout. What the desktop copy actually missed is that Orca classifies errors it built itself, with the Git output on `.stdout`: `worktree remove`'s submodule retry attaches `git status --porcelain` that way on both paths. The stdout-reading form is also already the shared spelling — `isSubmoduleWorktreeRemovalRefusal` uses it for both hosts — so this converges on it rather than on the shorter one. Move the reader to src/shared/git-command-failure-text.ts and the predicate it feeds to src/shared/git-branch-delete-refusal.ts, and delete all three copies. The predicate carries both refusal wordings live in the supported range: Git through 2.40 says "checked out at", 2.43+ says "used by worktree at". The real-binary contract now pins that boundary: the refusal is recognized, it lands on stderr, and stdout stays empty on every Git in the matrix. * fix(test): consolidate the duplicate worktree import in the parity test |

perf(git): answer remote-URL questions from one subprocess, not one per remote (#18158)
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) |

perf(git): pack the loose refs Orca's own fetches leave behind (#17857)
* perf(git): pack the loose refs Orca's own fetches leave behind Orca strips git's auto-maintenance off every fetch it issues (GIT_FETCH_SKIP_AUTO_MAINTENANCE_CONFIG_ARGS) and never compensated, so nothing in an Orca-driven checkout ever packs refs. One real machine reached 36,574 loose refs, where `git show-ref -- main` costs 5.2s and every worktree create pays for it. Add an idle-time, per-repo `git pack-refs --all --prune`, armed by the fetches that create the debt. It runs only after ten minutes of quiet on that repo, only above 1000 loose refs (probed with a walk bounded by that threshold, not by the backlog), one at a time across the whole app, at the background admission tier, and never while an agent is working, a create is prepared or in flight, a worktree removal is deleting refs, the app is quitting, or the machine is on battery. A user who set `maintenance.auto=false` or `gc.auto=0` has opted out. Measured on a 36,001-loose-ref fixture (macOS/APFS, git 2.44): `show-ref` 5.5-12.2s -> 30-49ms, `for-each-ref` 4.0-10.8s -> 43-48ms. Also fixes a pre-existing bug the split exposed: `--path-format=absolute` is ignored before git 2.31, and taking rev-parse's stdout raw collapsed every repo on such a host onto one fetch-serialization key. Refs #17828 * perf(git): make idle ref maintenance preemptible and cheaper to probe The idle veto was one-directional: it stopped a pack from starting during a create, removal, or agent work, but nothing stopped those from starting during a pack. A user-clicked Fetch, a branch delete, or a worktree removal that needed `packed-refs.lock` mid-rewrite could fail with `unable to create packed-refs.lock` -- a git error with no visible cause. Make the pack cancellable end to end. An AbortSignal now reaches the `pack-refs` child and both pre-pack probes, and `pause()` aborts what is running, waits for it to actually stop, and holds a suspension count so nothing new starts until the caller releases. Every entry point that deletes a ref takes that pause: gitFetch, gitPull, gitFastForward, removeWorktree, forceDeleteLocalBranch, prepareWorktreeCreateCheckout, addWorktree. Five more triggers close the rest of the window: battery drop, window focus, quit, the attempt deadline, and any other git command queueing for an admission slot. Judge a pack by re-probing the backlog rather than by the child's exit code. Measured in the field: another Orca session moved a branch mid-pack, git reported `cannot lock ref`, skipped that ref and packed the rest -- 36,688 loose refs down to 3. On a machine running several sessions that is the normal case, and retrying it would be wrong. Probe with one batched `readdir` per directory instead of streaming `opendir`, which issues a thread-pool round trip every 32 entries: 177ms -> 23ms on a real 36,600-ref repository, with half the event-loop lag. The walk stays strictly sequential so it can never occupy more than one of libuv's four filesystem threads. `PackRefsLockOwnership` makes a lock left by SIGKILL attributable, and only reclaims one when a marker exists, the lock is older than any pack-refs could run for, and the recorded process is gone. Refs #17828 * fix(git): wait out the packed-refs lock instead of killing the pack Measured on Git 2.55/APFS with 37k loose refs: a full `pack-refs --all --prune` takes 23-32s but holds `packed-refs.lock` for only 0.03-1.37s of it. The other ~95% is the prune phase, during which a concurrent `fetch --prune`, `branch -D` or `update-ref` succeeds every time -- per-ref locks last microseconds and git retries for `core.filesRefLockTimeout`. So the abort-on-everything design was strictly harmful. SIGTERM into the prune loop strands an empty `refs/**/*.lock` about one time in five (9/30, 5/40, 6/30 kills): `tempfile.c` opens the lock O_EXCL before `activate_tempfile()` links it into the list the signal handler walks, and a pack does ~36k lock cycles. Afterwards `update-ref -d` on that ref fails with `cannot lock ref ... File exists`, permanently. On Windows `taskkill /f` never runs git's handlers at all, so an abort inside the rewrite strands `packed-refs.lock` every time. Never signal the child. `packRefs` no longer takes an abort signal; it polls `packed-refs.lock` and reports the window through a `PackedRefsLockReporter`. `pause()` resolves when the lock is released -- bounded, and free during the prune -- while the suspension counter still blocks new attempts. Battery and window-focus become do-not-start rather than stop-what-is-running, and quit waits for the lock and lets the child finish orphaned. For strands that already exist, `PackRefsLockOwnership` now also reclaims `refs/**/*.lock` under the same three conditions plus a 0-byte check, and a lock carrying our own not-yet-reclaimable marker records `locked` with a 30min retry instead of the 6h failure cooldown -- so a Windows strand self-heals in half an hour rather than six. Reverts the git admission-scheduler event bus, which existed only to drive the abort this removes. Refs #17828 * test(git): make the ref-maintenance waits survive a loaded runner CI shard 4/8 failed on `restarts every armed countdown when the user does ref work themselves`, which passes locally. The `until()` helper spun a fixed 200 event-loop turns and then returned silently, so on a contended runner the filesystem probe had not finished and the assertion that followed failed with an unrelated message. Bound the wait by wall clock instead and throw a named error, which immediately exposed a second latent bug: the single-flight test's second wait could never succeed, because the deferred repo's retry is on a faked `setTimeout` that spinning the real loop never advances. It had been passing only because the old helper gave up quietly. Add a timer-aware variant for those, and have the countdown test await a signal the fake pack resolves rather than polling at all. Verified stable across five sequential runs and once under load average 32 with six concurrent suites. Refs #17828 |

fix(git): recover commit ref badges on Git older than 2.43 (#17923)
GIT_HISTORY_COMMIT_FORMAT asked for decorations with %(decorate:…), which Git 2.43 introduced. Older Git prints the placeholder verbatim and exits zero, so nothing raised and every commit in the Source Control panel silently lost its branch, remote and tag badges. The record now also carries %D (Git 2.10) on its own line, selected by an exact match against the unexpanded placeholder — a ref name can never contain the \x1f that Git expands inside the echoed text. %n emits the %D line on both sides of the boundary, so the message index is fixed and a missed match degrades to no badges rather than a corrupted message. The decoration separator is now bound to the field that produced the text instead of sniffed from it. A lone decoration carries no separator, so the old sniff split `refs/heads/feat,one` into two bogus refs. Verified against real Git 2.38.1 and 2.49.1.

perf(git): bound ref and worktree scans (#17655)
* perf(git): bound ref and worktree scans * fix(repo-search): clamp oversized ref limits * fix(worktree): keep strict worktree listing unshared The shared-scan re-export flipped every `listWorktreesStrict` caller from an isolated subprocess to the coalesced scan. `git worktree prune` in the removal recovery path does not bump the scan generation, so a post-prune verification could join a pre-prune scan, see the stale row, and report a successful removal as a stale registration. The same gap defeats the post-archive-hook rechecks that exist to catch an external Git client locking the row. Restore the unshared export and make coalescing opt-in via `listWorktreesSharedStrict`, which existing callers already use deliberately. * fix(git): separate a proven absent ref from a failed probe `show-ref --verify --quiet` exits 1 for a missing ref, but so does `wsl.exe` when its own launch fails, so reading any exit 1 as absence collapsed `unverifiable` into `exited`. A genuine miss prints nothing while a wrapper failure always explains itself, so require empty stderr alongside the exit code; a runner that reports no stderr at all keeps its exit-code contract. That same signal removes a spawn regression: `show-ref` is a direct-git read under WSL, and the runner retried any numeric exit through the user's interactive login shell. The replaced `for-each-ref` exited 0 on a miss, so absence never retried; every absent probe now would. Treat a quiet exit 1 as Git control flow and skip the fallback. Also narrow the hosted-review suffix fallback: the replaced `refs/remotes/*/<base>` could not cross a slash, but `show-ref -- <base>` matches at any depth, so `origin/feature/main` answered a query for `main` and submitted a review against a base the provider rejects. Refresh the real-binary compatibility contract to the shipped excludes, and assert exact probe concurrency rather than an upper bound so a regression to serial probing fails. |

Fix rebase race by fetching to private ref before rebasing (#15990)
* 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

perf(git): reuse pinned OIDs for SSH file diffs (#13586)
Forward the renderer's already-pinned {mergeBase, headOid} to the SSH relay so a single-file branch diff reads the two blobs directly instead of rediscovering live HEAD. Six sequential git processes become two concurrent reads, and a branch move mid-review no longer changes which revision is displayed.
Equivalence with the legacy route is proven against real Git across 14 change types; wire compatibility is proven over a real SSH socket against relay bundles built from main and from the pre-merge-base.

perf(worktrees): delete worktree directories after the removal returns (#12416)
* perf(worktrees): delete worktree directories after the removal returns `git worktree remove` deleted the whole checkout inline, so the remove IPC held the watcher/PTY gate for the entire recursive delete (prod traces: worktree.remove.git_remove p50 8-14s, p90 29s, max 34.7s). Local removals now rename the checkout into a hidden sibling trash root, clear Git's registration for the missing path, and delete the moved tree in the background. Renames that cannot run (WSL, other volume, Windows open handles) fall back to the previous in-place removal unchanged. * test(worktrees): keep no empty trash root when the rename cannot run * fix(worktrees): harden deferred trash cleanup * fix(worktrees): keep WSL trash on its owning host |

fix(git-history): stop reading the option marker as the resolved ref name (#10906)
`rev-parse --verify` swallows --end-of-options, but --symbolic-full-name deliberately echoes it -- on every git version tested, 2.25 through 2.49: $ git rev-parse --symbolic-full-name --end-of-options feature --end-of-options refs/heads/feature resolveSymbolicFullName took the first non-empty line, so it returned the literal string "--end-of-options" instead of the ref. That value flows into gitHistoryRefFromFullName, matches none of the refs/heads, refs/remotes, or refs/tags prefixes, and every named branch and tag in git history was silently categorized as a plain commit with a garbage id. Skip the marker line. Version-independent bug; no test covered it. Also pins git's echo behavior in the real-binary compatibility suite, so if a future git stops emitting the marker the reason for the skip gets re-read rather than the assumption quietly rotting.

Fix fork PR/MR worktree creation race via durable review-head refs (#10429)
* Fix fork PR/MR worktree creation race via durable review-head refs
When creating a fork PR/MR worktree, concurrent `git fetch origin` operations
clobber the shared FETCH_HEAD, causing the wrong commit to be checked out.
Fetch PR/MR heads into dedicated per-review refs (`refs/orca/pull/<N>`,
`refs/orca/merge-requests/<N>`) that persist and isolate each head from other
fetches. Gracefully keep the compare-base when the fetch fails but the local
ref already exists, avoiding silent fallback to the wrong branch on transient
network errors.
* Bound PR/MR head fetches with 60s timeout
Prevent PR/MR creation from hanging when a remote is stalled or
unreachable. Both GitHub and GitLab head fetches now enforce a
60-second timeout, matching the bound used in the create-path
fetch. Durable refs (refs/orca/pull/*, refs/orca/merge-requests/*)
decouple the ref from FETCH_HEAD, preserving legacy client semantics.
* test: align CI expectations with main PowerShell/sparse regressions
PR checks merge into main, which recently changed PowerShell launch args
(cwd restore after profiles) and sparse-checkout detection (require
core.sparseCheckout). Derive PowerShell spawn args from the production
resolver, mock the sparse config flag, reset shared worktree list scan
cache between tests, and stop requiring floating polls to avoid getRepos
hydration.
* Address review follow-ups on durable review-head refs
- Unify PR review-head remote selection: local and SSH GitHub paths share
resolveGitHubReviewHeadRemote, which prefers the remote mapping to the
hosting GitHub project (upstream before origin, matching work-item/API
candidate order) so contributor clones fetch refs/pull from the repo
that actually hosts the PR.
- Soft-keep durable review heads: when the PR/MR head fetch fails but
refs/orca/pull/<N> / refs/orca/merge-requests/<iid> still resolves,
keep the pinned SHA (warn) instead of failing resolve, mirroring the
compare-base fallback. Extracted shared compare-base soft-keep into
compare-base-ref-fetch.ts.
- Extract fetchGitLabMergeRequestHeadRef (local + SSH) parallel to the
GitHub helper; bound its local fetch with the shared 60s timeout.
- Share relay-style fetch validation (positive safe-integer id, remote
not starting with "-") between relay and local helpers via
review-head-tracking-ref.ts; move REVIEW_HEAD_FETCH_TIMEOUT_MS there.
- Drop the githubPullRequestHeadLocalRef re-export; resolve head SHAs via
rev-parse --verify <ref>^{commit}.
- Add GitLab anti-FETCH_HEAD regression test plus durable-head soft-keep
and remote-selection unit tests.

* test: supply live getRepos for terminal-retirement hydrates
Main's headless tab hydrate (#9343) skips worktree keys whose repo is not
in getRepos. Retirement tests that rebuild mobile tabs from a persisted
session now advertise the fixture repo as live so PR Checks merge stays green.
* fix(editor): extract RichMarkdownEditor props to stay under max-lines
Main's SSH external-image wiring (#10323) pushed RichMarkdownEditor.tsx over
the 400-line tsx budget, failing PR Checks lint on every merge into main.
Move the props type into a sibling module so the component stays under the
limit without disabling max-lines.
* Make durable review-head refs remote-identity scoped
Embed remote name + URL hash into refs/orca/pull|merge-requests refs to prevent soft-keep from serving wrong project's PR/MR when FETCH_HEAD is clobbered by concurrent fetch. Fetch functions now return the written ref path (writer-authoritative) so callers rev-parse exactly what was fetched, not re-derive identity. Soft-keep only applies to transient errors (timeout, network); fails hard on missing refs, auth failures, and stale relay. Relay returns localRef so client avoids re-hashing (URL normalization can disagree).

fix(worktrees): stop surfacing prunable git worktrees as live workspaces (#8409)
* fix(worktrees): stop surfacing prunable git worktrees as live workspaces A worktree still registered in git but whose directory was deleted (git's `prunable` state) was enumerated as a normal workspace, producing repeated pty:spawn DaemonProtocolError / fs:readDir ENOENT loops and a blank pane. - Parse the `prunable` porcelain field (Git >= 2.36) in both the main and relay worktree-list parsers. - For Git < 2.36 (no `prunable` field), probe each linked worktree path for existence on the fallback line-block path, skipping locked registrations to mirror git's own prunable rules. - Omit prunable worktrees from the detected-workspace enumeration only; removal/cleanup flows keep seeing them. - Extend the real-binary compatibility contract with the 2.36 `prunable` boundary. Fixes #8389 Claude-Session: https://claude.ai/code/session_018Rg1Bpq4GGwmz613hq6RSD * fix(worktrees): pin the prunable/locked porcelain annotations to their real Git 2.31 boundary The prunable and locked annotations landed in Git 2.31, five releases before `worktree list -z` (2.36); only -z defines the capability fallback boundary. Correct the compatibility contract so a future matrix entry in the 2.31-2.35 range passes, and reword the fallback comments: on 2.31-2.35 the annotations still parse and the existence probe is a backstop; only Git <2.31 relies on it outright. * fix(worktrees): omit prunable registrations from the Space scan A prunable registration has no directory to size or reclaim, so Space rendered it as a dead "Missing" row whose checkbox stayed disabled with no prune/remove affordance (reported on macOS after a reboot cleared /private/tmp under 16 registrations). Skip prunable entries in the scan, matching the workspace enumeration; removal flows list worktrees separately and still see them. --------- Co-authored-by: kaynan <kaynan.camargo@terceiro-sky.com.br> Co-authored-by: Brennan Benson <79079362+brennanb2025@users.noreply.github.com> |

Suppress Git Credential Manager OAuth popup loop in Orca-run git — clone, terminals/agents, setup hooks (fixes #7652) (#7986)
* Suppress Git Credential Manager OAuth popup on git clone (fixes #7652)
Orca's git runner disables the interactive credential prompt on every git
call that goes through gitExecFileAsync/gitStreamStdout, but the two raw
'git clone' spawns (desktop repos:clone and the runtime clone path) passed
no env, so they inherited process.env with no guard. On Windows a clone
that needs GitHub auth then makes Git Credential Manager pop its
'Connect to GitHub' OAuth window, and in a network-restricted intranet the
browser/device flow never completes while git's credential retry re-pops it.
Apply nonInteractiveGitEnv() to both clone spawns so the prompt is
suppressed (GCM_INTERACTIVE=never, credential.interactive=false,
GIT_TERMINAL_PROMPT=0). The credential *helper* is kept, so cached-token
clones for private repos still work; only the interactive fallback popup is
disabled and the clone fails fast with a clear error instead.
* Suppress GCM OAuth popup in agent terminals and setup hooks too (#7652)
The clone-spawn fix stopped Orca's own managed git from popping Git
Credential Manager, but git run in terminals and setup scripts inherited
process.env with no guard. That is the more likely source of the reported
loop: agents are told to run 'git pull --rebase'/'git fetch'/retry 'git
push' (preamble + conflict/push-failure prompts), and each retry re-pops
GCM's 'Connect to GitHub' window in a network-restricted intranet.
Apply the credential-prompt guard to:
- setup/archive/hook scripts (hooks.ts non-WSL exec env), which run
unattended on worktree create/archive.
- the shared PTY host env (buildPtyHostEnv), via a small
applyTerminalGitCredentialPromptGuard helper. Agent terminals are
guarded unconditionally (they cannot dismiss a GUI popup); user
terminals are guarded by default via the new
terminalSuppressGitCredentialPrompt setting so power users can opt out.
The credential helper is kept, so cached gh auth still works; only the
interactive fallback prompt is disabled. Verified end-to-end in a real
Orca terminal (GIT_TERMINAL_PROMPT=0 + GCM_INTERACTIVE=never by default;
absent when the opt-out is set).
