Gavin Mak ead4b2d7aa sync: Implement fetchcmd for standard Git layouts
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 \
    --no-repo-verify \
    --use-local-gitdirs
...

> git config --file .repo/manifests.git/config repo.fetchcmd 'mkdir -p $REPO_PATH && cd $REPO_PATH && if [ ! -d .git ]; then git init && git remote add aosp $REPO_PROJECT_FETCH_URL; fi && git fetch aosp $REPO_TREV && git reset --hard $REPO_TREV && mkdir -p .git/refs/remotes/aosp && echo $REPO_TREV > .git/refs/remotes/aosp/main && echo $REPO_TREV > .git/FETCH_HEAD'

> ~/git-repo/repo sync -j32

Brian Gan e7cac4bca6 status: Show ahead/behind info for local branches
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.

Gavin Mak 88a7e88e54 info: Report actual checked-out HEAD revision
When `repo info` runs, the reported "Current revision" is resolved using
the manifest's target branch tracking ref (e.g. refs/remotes/goog/main).

Introduce Project.GetHeadRevisionId(), which gets the checked-out HEAD
commit in the worktree, and use it in `repo info` with a fallback to the
old behavior if the project is not checked out.

Sainath Varanasi 3af9e2f146 project: fix sync of shallow projects sharing objdir
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

Xin Li c883613e31 sync: Skip copyfile/linkfile for unavailable projects
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.

Josef Malmström 1db50e49fb Add support for self referencing submodules
When working with relative submodule paths, The "./" needs special
handling similar to "../".

See information on:
https://git-scm.com/docs/git-submodule
Which currently states:
"<repository> is the URL of the new submodule’s origin repository.
This may be either an absolute URL, or (if it begins with ./ or ../),
the location relative to the superproject’s default remote
repository (Please note that to specify a repository foo.git which is
located right next to a superproject bar.git, you’ll have to use
../foo.git instead of ./foo.git - as one might expect when following
the rules for relative URLs - because the evaluation of relative URLs
in Git is identical to that of relative directories)."

The implementation also was not handling file/directory names
starting with "." or "..". Explicitly look for "./" and "../"
instead.

Carlos Fernandez 5534f164d6 linkfile: Handle directory-to-symlink transitions safely
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

Becky Siegel b43a20b859 project: Avoid skipping fetches for shallow clones without .git/shallow
When optimizing fetches for projects with immutable revisions, the fetch
should not be skipped if the project is configured for a shallow clone
(depth > 0) but the .git/shallow file is missing. The absence of the
.git/shallow file means the repository is not a shallow clone, or the
shallow clone is incomplete, so a fetch is necessary to ensure the
revision is present.

Miyako.Enei 8869a30283 project: Drop --no-deref from update-ref --stdin
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.

Tested with:
  - Git 2.17.1
  - Git 2.34.1

Kaushik Lingarkar 50c6226075 Prevent leftover bare gitdirs after failed sync attempts
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.

Peter Kjellerstedt 412367bfaf project: Use dicts to keep track of copyfiles and linkfiles
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.

Jeroen Dhollander e4872ac8ba sync: Use 'git rebase' during 'repo sync --rebase'
'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 :(

Kaushik Lingarkar 4623264809 Fix submodule initialization in interleaved sync mode
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.

Krzysztof Wesolowski d9cc0a1526 Fix shallow clones when upstream attribute is present
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.

hand, when repo synchronize a projcet with submodules inside, it

When a project contains submodules, project.py parses the .gitmodules

option. Consequently, this parameter is not propgated to newly
created Project instance for that submodule.

During such operation, git is restoring workspace based on the current

host. That will leave affected repository in a bad state with partially
