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.

cherry_pick: resolve and read commits in one process

Send a typed revision expression to cat-file --batch over stdin and parse its object header and exact byte length. This safely resolves the commit OID and retrieves its raw message in one Git process instead of separate rev-parse and cat-file calls.
