Introduce support for `repo.fetchcmd` configuration, allowing users to
specify a custom command to fetch project data instead of
`_RemoteFetch`.
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.
Tested with:
```
> ~/git-repo/repo init -u https://android-review.googlesource.com/platform/manifest \
--repo-url file:///usr/local/google/home/gavinmak/git-repo \
--groups developers \

When viewing `repo status`, it is difficult to distinguish between branches that have active unpushed changes and stale branches that are fully synced. Previously, developers had to run commands like `repo forall -c "git status"` to see their ahead/behind counts.
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.
If the branch is completely synced with upstream, no extra text is shown.
Added tests for ahead-only, behind-only, diverged, no-tracking, and fully-synced branch states.

Repo sync fails when the following conditions are met:
* There are several checkouts of the same project
in different paths.
* The checkouts are using git hashes as revisions
(not branches).
* There is a clone-depth set on these projects.
* sync-c="true" is set in the manifest.
* The revision specified in the manifest
has moved forward since the first repo init.
The sync fails because only the first gitdir gets the "shallow" file,
and subsequent dirs can't be synced.
Do not optimize away the fetch when the conditions above happen.
Simplified the boolean check in Sync_NetworkHalf and _RemoteFetch
using has_shallow, renamed loop variable to avoid shadowing.
Test: create a manifest matching conditions above, repo init,
forward the hash, and repo sync.
Test: added tests in test_project.py

Commit 5534f16 made UpdateCopyLinkfileList to retry _CopyAndLinkFiles
for all projects in the manifest to handle directory-to-symlink
transistions. However, for partial sync's (e.g. repo sync <project>),
projects not included in the sync may not have their local directories
populated, attempts to perform the operation on unavailable projects
would result in dangling symlinks, or errors like:
error: Cannot copy file <source> to <destination>
Fix this by adding a check inside _CopyAndLinkFiles in project.py to
so these operations happen only when the project's worktree exists
and is a directory.

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

repo calls `git update-ref --stdin` when updating multiple refs during
repo init and repo sync. Historically, `--no-deref` was also passed.
Older Git 2.17 which we still support rejects the combination of
`--stdin` and `--no-deref`, emitting a usage error even when the stdin
input is valid.
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.

- Git 2.17.1
- Git 2.34.1

For Python 3.7+, maintaining the order that keys are added to dicts is

This was broken by

This caused *multiple* actual editor windows to pop up (*) during

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

The _CheckForImmutableRevision method was modified in commit 0e776a58 to
include upstream branch validation for superproject scenarios. However,
this change inadvertently broke shallow clones when both clone-depth and
upstream attributes are specified in regular (non-superproject)
manifests.
Issue: When upstream is present, _CheckForImmutableRevision performs two
additional checks: 1. git rev-list on the upstream reference 2. git
merge-base --is-ancestor between revision and upstream
In shallow clones, the upstream branch history may not be available
locally, causing these checks to fail. This triggers the retry mechanism
that removes depth limitations, effectively converting shallow clones to
full clones, resulting in excessive disk usage.
Fix: Make upstream validation conditional on superproject usage. This
preserves the original superproject fix while restoring the method's
original behavior for regular scenarios - checking only if the immutable
revision (SHA1/tag) exists locally.
Note: The SetRevisionId method from the same commit 0e776a58 is left
unchanged as it only stores upstream information (no git operations),
which is beneficial for preserving branch context for commands like
'repo start' without causing fetch-related issues.
The fix ensures that manifests with both clone-depth and upstream work
correctly in non-superproject scenarios, maintaining shallow clone
efficiency and reducing disk usage.

host. That will leave affected repository in a bad state with partially
checked out workspace. The follow up repo sync won't try to fix such
