sync: skip the bloat check for projects without a worktree

2026-09-23T20:27:01+00:00

Skip shallow clone bloat checks during --network-only syncs and filter out projects whose worktree directory does not exist on disk. Also return None quietly from _GetStatusSnapshot() when a project lacks an existing worktree directory.

project: don't rerun git status after a failed snapshot

2026-09-23T20:26:55+00:00

When a status snapshot fails, fall back directly to _IsDirtyLegacy() instead of IsDirty() to avoid running git status twice. Expose Project.GetDirtyAndHead() so sync bloat checks can inspect worktree state without invoking private Project methods.

info: reuse branch snapshots and combine history walks

2026-09-21T20:40:06+00:00

Derive the current branch from GetBranches so attached HEAD and refs are resolved once, including overview reporting. Replace the two complementary rev-list calls in --all output with one --left-right symmetric-difference walk and partition its records in memory.

project: make fast-forward merges explicit

2026-09-21T20:39:56+00:00

Every caller expects _FastForward to reject a merge commit. Always pass --ff-only and remove the optional parameter so a violated ancestry assumption fails instead of silently creating a merge.

sync: reuse status HEAD in the bloat scan

2026-09-21T20:39:21+00:00

The shallow-project bloat check already needs dirty state. Request branch metadata in that same porcelain-v2 snapshot and use branch.oid instead of launching a separate rev-parse, with the existing calls retained as a fallback.

command: preserve project filters in regex selection

2026-09-16T11:54:02+00:00

`FindProjects` gets its candidate projects from `GetProjects` and then applies regex matching. However, it only forwards `all_manifests`, so other project filters are lost on regex paths. As a result, `repo forall -r/-i --groups` falls back to the configured group selection instead of using the requested groups. Similarly, `repo list -r --groups` ignores the requested groups, and `repo list -r --all` still excludes projects without a checkout. Pass `groups` and `missing_ok` through `FindProjects`, and forward the existing options from `forall` and `list`. When no group override is given, keep using each manifest's effective groups. Add regression tests for `FindProjects` and both command paths.

sync: keep generated jobs-checkout help host-independent

2026-09-16T11:51:54+00:00

The default shown for `--jobs-checkout` comes from `DEFAULT_LOCAL_JOBS`, which depends on the host CPU count. As a result, regenerating the sync and smartsync manpages on a different machine can change their output even though repo's behavior has not changed. Use shared CPU-based help formatting for `--jobs` and `--jobs-checkout`. Interactive help still shows the actual default, while generated manpages describe it without including a host-specific value. Runtime job selection is unchanged. Add coverage for both help modes and regenerate the affected manpages.

sync: implement reprojectcmd for the local half

2026-09-15T19:53:01+00:00

Add `repo.reprojectcmd`, the checkout counterpart to `repo.fetchcmd`. When set, `repo sync` runs this command instead of Git to materialize a project's index and worktree at the target tree, while `repo` handles ref updates directly via `git update-ref`. This replaces Git's tree materialization steps: detaching HEAD, fast-forwarding, and hard-resetting. Rebasing is not delegated, and the command is skipped if HEAD is already at the target, if HEAD is ahead of the target during fast-forward, or for MetaProjects. The command runs in a subshell with project environment variables (such as `REPO_TREV`). Before running, `repo` ensures no operation is in progress and no staged changes exist. Worktree collision detection is delegated to the command (preserving benign unstaged/untracked edits). Afterward, `repo` verifies that HEAD was untouched and that the index matches the target tree. Like `repo.fetchcmd`, this requires `repo.uselocalgitdirs`. Nested projects and submodules are unsupported; `repo sync` fails if the manifest contains any while `repo.reprojectcmd` is enabled. Verified end-to-end with repo init using local-gitdirs, repo.fetchcmd, and repo.reprojectcmd ('git -C $REPO_PATH read-tree -m -u $REPO_TREV'): * Verified detached HEAD checkout and correct reflog generation across projects. * Verified benign unstaged edits and untracked files survive checkout. * Verified conflicting untracked files fail with exit 128 without clobbering worktree. * Verified staged changes fail upfront before reprojectcmd is executed.

upload: bypass branch editor with explicit branch and -y

2026-09-09T19:10:24+00:00

When uploading across multiple projects with --yes and an explicit branch specified (via --current-branch / -c or --branch / --br), repo previously still opened the interactive branch selection editor. If an explicit branch and --yes are provided, bypass the interactive editor and upload all matching pending branches directly.
