In _CheckForImmutableRevision, commit d9cc0a15 restricted upstream ref
validation strictly to superprojects (if use_superproject) to prevent
shallow clones with an upstream attribute from failing ancestry checks
and falling back to full clones.
However, restricting this check exclusively to superprojects broke
non-shallow projects with pinned immutable revisions (such as in Smart
Sync, `repo sync -t <BUILD_ID>`, or pinned manifests): When the target
commit already exists in the local Git object store (for instance,
prefetched into refs/prefetch/ by a background daemon or via shared
object dirs), _CheckForImmutableRevision returned True without verifying
that the local tracking ref (refs/remotes/<remote>/<upstream>) is
present and reaches the revision. As a result, _RemoteFetch skipped
fetching the upstream branch, leaving the local tracking ref stale or
missing. Subsequent `repo start` branches tracking that remote branch
diverged, causing `repo upload` to attempt uploading all intermediate
commits between the stale tracking ref and HEAD.
Restore upstream ancestry validation in _CheckForImmutableRevision for
non-shallow projects when upstream is specified. Also pass the sync
depth into _CheckForImmutableRevision call sites so shallow checkouts
continue to skip upstream verification and avoid triggering un-shallow
fallbacks.

Benchmark (100 untouched projects):
* GetUploadableBranches: 0.985s -> 0.0004s (2,200x faster)
* repo upload (3,045 projects): saves ~2.5s of redundant ref scans
During `repo upload`, `GetUploadableBranches()` currently scans
`self._allrefs` across all projects in the workspace. In large
manifests (e.g. Android with 3,000+ projects), `self._allrefs`
executes `git for-each-ref`, `git symbolic-ref`, and full filesystem
mtime traversals on thousands of projects where no local branch was
ever started or modified.
Any branch that can be uploaded for review must have upstream tracking
configured via `[branch "..."]` sections in `.git/config`
(otherwise `branch.LocalMerge` is None and `GetUploadableBranch`
returns None).
This patch introduces early-pruning fast paths:
1. When no branch subsections exist in `.git/config`
(or only 2-part keys like `branch.autosetupmerge`), return []
immediately without touching `_allrefs`.
2. When a `selected_branch` is specified (e.g. `repo upload --br=...`),
query `branch.LocalMerge`, `refs/heads/<branch>`, and
`refs/published/<branch>` directly, skipping the whole-tree
ref scan.
3. In `subcmds/upload.py`, optimize `_GetMergeBranch` to resolve the
merge branch in-memory via `project.CurrentBranch` and
`project.GetBranch()` instead of spawning two `GitCommand`
processes.

From repo's inception through v2.56, GetHead() directly read the
`.git/HEAD` file in Python. In commit 52bab0ba ("project: Use git
rev-parse to read HEAD"), this was replaced with git subprocess calls
on the premise that git provides a dedicated command. However, in
large multi-project workspaces (such as Android with 3,000+ projects),
spawning thousands of git processes introduced severe latency
regressions during `repo upload` and `repo status`.
Furthermore, switching to subprocesses broke detached HEADs and
unborn branches (fixed in commits 7f7d70ef and 8c3585f3 by re-adding
the v2.56 file-reading logic as an error recovery fallback).
This patch restores fast in-memory reading as the primary path, while
adding modern defensive safeguards:
* Symbolic refs (`ref: refs/heads/...`): Strips whitespace and tabs
and returns the ref directly in memory.
* Detached HEAD: Validates 40-char SHA-1 and 64-char SHA-256 commit
hashes via git_config.IsId(), normalizing to lowercase.
* Symlinks: Detects filesystem symlinks via os.path.islink() and
safely falls back to git symbolic-ref.
* Fallback: Catches (OSError, AssertionError) and transparently falls
back to native git commands for reftables, unexpected layouts, or
filesystem errors. Unifies recovery fallback parsing with the fast
path (CRLF/tabs, lowercase hashes, and consistent RelPath errors).
In addition, this change substantially expands test coverage in
tests/test_project.py, adding comprehensive unit tests for symbolic
refs, whitespace/tabs, CRLF line endings, SHA-1, SHA-256, uppercase
hash normalization, symlinks, corrupted worktrees, and fallback
robustness.

It drew that fallback from dest-branch and from the manifest <default>
upstream, dest-branch, and revision. dest-branch and tags are not valid
fallback candidates:
* dest-branch is the review destination for upload, not a fetch
source.
* Tags are meant to be immutable snapshots of a single tagged commit,
and fetching it cannot retrieve an arbitrary pinned SHA-1.
Restrict the fallback to branch heads resolved from the manifest
upstream and revision defaults, and drop dest-branch entirely.

A discovered submodule becomes a project whose revision is the gitlink
read from its parent at manifest load time, which is before the parent
has been fetched. Remember which gitlink a submodule was derived from,
and add a way to read those gitlinks again, so that callers can resolve
a submodule revision once its parent is up-to-date.
A revision that is set does not have to be fetched, so verify its
objects are really there. Without them a submodule that was removed
cannot be told apart from one that was never fetched, which the caller
has to know about.

The superproject-gated upstream check in _CheckForImmutableRevision
only applies to user projects listed in the manifest. MetaProjects
(ManifestProject and RepoProject) never participate in a superproject
relationship, so evaluating git_superproject.UseSuperproject(...,
self.manifest) for them serves no purpose and, worse, calls the
manifest.superproject property which forces a manifest load.
During repo init, ManifestProject._ConfigureDependencies calls
self.Sync_NetworkHalf before manifest.xml has been linked into
.repo/. That reaches _CheckForImmutableRevision, which triggered the
manifest load and failed with:
ManifestParseError: .../.repo/manifest.xml: [Errno 2] No such file
or directory
breaking fresh repo init with SHA-based --manifest-branch combined
with --manifest-upstream-branch.
Factor the "should we consult the superproject for upstream?"
decision into a small overridable hook, _UseSuperprojectForUpstream.
Project's default delegates to git_superproject.UseSuperproject;
MetaProject overrides it to return False, localizing the
MetaProject-specific behavior to MetaProject.
Test verifies that calling _CheckForImmutableRevision on a
ManifestProject whose manifest.xml is not yet on disk returns False
without raising and does not create the file.

Introduce support for `repo.fetchcmd` configuration, allowing users to

When `repo.fetchcmd` is specified, `repo` will execute it instead of
`_RemoteFetch` during the network half of sync. Note that
`repo.fetchcmd` requires `repo.uselocalgitdirs` to be enabled.
The command is executed in a subshell with project-context environment
variables, including the new `REPO_TREV` (target revision resolved to a
commit hash) and `REPO_PROJECT_FETCH_URL`.
After execution, `repo` verifies that the target commit is available and
that the tracking ref and FETCH_HEAD are correctly updated.

This change updates Project.PrintWorkTreeStatus to automatically calculate and display the number of commits a branch is ahead and/or behind its upstream tracking branch. We use `git rev-list --left-right --count` to fetch this information natively and efficiently.

* There is a clone-depth set on these projects.
* sync-c="true" is set in the manifest.
* The revision specified in the manifest

The sync fails because only the first gitdir gets the "shallow" file,

When a manifest changes from individual linkfiles inside a directory
(e.g. dest=".llms/rules", dest=".llms/skills") to a single linkfile
for the whole directory (e.g. dest=".llms", src="dot-llms"), two
things need to happen:
1. __linkIt must replace a real directory with a symlink. Use
os.rmdir() instead of platform_utils.remove() for real directories.
rmdir only removes empty directories, so user-created content is
never deleted.
2. UpdateCopyLinkfileList must handle the cleanup correctly:
- Use os.rmdir() for directories (safe for non-empty)
- Remove empty parent directories after cleaning old dests
- Retry _CopyAndLinkFiles for all projects, since in interleaved
sync mode _CopyAndLinkFiles runs before cleanup and may have
failed because the directory was not yet empty

The `--no-deref` option is only meaningful when updating symbolic refs
such as HEAD. The stdin-based update-ref path only operates on explicit
refs (tags, remote refs, alternates) and never symbolic refs.
Remove the unnecessary option to restore compatibility with Git 2.17
while preserving identical behavior on newer Git versions.
Tested with:
- Git 2.17.1
- Git 2.34.1

Implement in-situ shallow re-fetching and garbage collection logic.
Enables repositories with sync-strategy="stateless" to reclaim disk
space by running reflog expire and git gc --prune=now if the working
tree is clean and has no local commits.

The only supported sync-strategy is "stateless". The intent is to keep
the local workspace as small as possible by not keeping history during
syncs. This prevents disk space waste for projects with large binaries
where we only care about the current version.
A follow up change will implement the logic.

If a user has manually unshallowed a repo (e.g. via
`git fetch --unshallow`), the absence of the `shallow` file in the
gitdir indicates a full clone. Re-applying depth during a subsequent
sync would undo the user's intent. Skip re-shallowing in this case
by clearing depth when the project is not new and no shallow file
is present.

Currently somewhere use git_superproject.UseSuperproject(), which checks
both the manifest config and user's config, and otherwhere use
manifest.manifestProject.use_superproject, which only checks the
manifest config. This causes Inconsistent behaviors for users who do not
set --use-superproject when doing repo init but have
repo.superprojectChoice in their git config.
Replace where using manifest.manifestProject.use_superproject with
git_superproject.UseSuperproject() to respect user's config and avoid
inconsistency.

During sync, `git checkout` can trigger fetch for missing objects in
partial clones. This internal fetch can trigger `git maintenance` or
`git gc` and cause delays during the local checkout phase. Set
maintenance.auto to false and gc.auto to 0 in during `_InitRemote` if
`depth=1` to ensure that implicit fetches spawned by git skip GC.

The gitdir for a project may be left in a state with bare=true due
to a previous failed sync. In this state, during a subsequent sync
attempt, repo will skip initializing the gitdir (since the directory
already exists) and directly attempt to checkout the worktree, which
will fail because the project is bare. To reduce the chance of this
happening, initialize the gitdir in a temp directory and move it once
it is ready.

This avoids copying/linking the same file/link multiple times if a
copyfile/linkfile element with the same values has been specifed
multiple times. This can happen when including a common manifest that
uses an extend-project element that has a copyfile/linkfile element.
This uses dicts rather than sets to store the copyfiles and linkfiles to
make sure the order they are specified in the manifest is maintained.
For Python 3.7+, maintaining the order that keys are added to dicts is
guaranteed, and for Python 3.6 it happened to be true.
The _CopyFile class and the _LinkFile class are changed to inherit from
NamedTuple to be able to store them in dicts.

'repo sync --rebase' should do a rebase if it encounters local commits
during a 'repo sync'.
This was broken by
https://gerrit-review.git.corp.google.com/c/git-repo/+/437421,
which caused this to execute the '_doff' hook (which stands for
'do fast forward'), which is implemented using 'git merge --no-stat'.
This caused *multiple* actual editor windows to pop up (*) during
'repo sync --rebase', asking the user to enter a commit message for the
merge.
In this CL I explicitly make that code path do a 'git rebase'.
(*) and if you use a terminal editor like 'vim', this means you have 2+ concurrent vim windows rendered in the same terminal, while 'repo sync' keeps on printing other output lines, again in the same terminal. The result is .... not pretty to say the least :(

With the introduction of interleaved sync mode, the submodule activation
logic broke because the 'has_submodules' attribute was no longer being
populated when needed. With this change, each submodule is initialized
when it enters the Sync_LocalHalf stage, whereas previously all
submodules were initialized at once when the parent repository entered
the Sync_LocalHalf stage. The init is now retried if it fails, as
submodules may concurrently modify the parent’s git config, potentially
causing contention when attempting to obtain a lock on it.
This change makes the submodule activation logic more robust and less
prone to breakage.
