68d69635c7 Fix Projects.shareable_dirs
If this tree is not using alternates for object sharing, then we need to
continue to call it a shared directory.

1d00a7e2ae project: initial separation of shared project objects
For now, this is opt-in via environment variables:
  - export REPO_USE_ALTERNATES=1

The shared project logic that shares the internal .git/objects/ dir
directly between multiple projects via the project-objects/ tree has
a lot of KI with random corruption.  It all boils down to projects
sharing objects/ but not refs/.  Git operations that use refs to see
what objects are reachable and discard the rest can easily discard
objects that are used by other projects.

Consider this project layout:
<show fs layout>

There are unique refs in each of these trees that are not visible in
the others.  This means it's not safe to run basic operations like
git prune or git gc.

Since we can't share refs (each project needs to have unique refs
like HEAD in order to function), let's change how we share objects.
The old way involved symlinking .git/objects/ to the project-objects
tree.  The new way shares objects using git's info/alternates.

This means project-objects/ will only contain objects that exist in
the remote project.  Local per-project objects (like when creating
branches and making changes) will never be shared.  When running a
prune or gc operation in the per-project state, it will only ever
repack or discard those per-project objects.  The common shared
objects would only be cleaned up when running a common operation
(i.e. by repo itself).

One downside to this for users is if they try blending unrelated
upstream projects.  For example, in CrOS we have multiple kernel
projects (for diff versions) checked out.  If a dev fetched the
upstream Linus tree into one of them, the objects & tags would
not be shared with the others, so they would have to fetch the
upstream state for each project.  Annoying, but better than the
current corruption situation we're in now.

Also if the dev runs a manual `git fetch` in the per-project to
sync it up to newer state than the last `repo sync` they ran,
the objects would get duplicated.  However, git operations later
on should eventually dedupe this.

630876f9e4 init: add an option --enable-git-lfs-filter
It was reported that git-lfs did not work with git-repo. Specifically,
`git read-tree -u` run by `repo sync` would fail git-lfs's smudge
filter. See https://github.com/github/git-lfs/issues/1422.

In fact, by the time `git read-tree -u` is run, the repository is not
bare. It is just that, the working directory is not the same as the
.git directory. git-lfs's filter should work. No one seems to have
delved into that issue.

Today, with newer versions of git-repo and git-lfs, that issue will
not reproduce. Tested with
- git 2.33, git-lfs 2.13 on macOS
- git 2.17, git-lfs 2.3 on ubuntu

So, it seems fine to add an option --enable-git-lfs-filter, default to
false, and stat that it may not work with older versions of git and
git-lfs in the help doc.

67d6cdf2bc project: store objects in project-objects directly
In order to stop sharing objects/ directly between shared projects,
we have to fetch the remote objects into project-objects/ manually.
So instead of running git operations in the individual project dirs
and relying on .git/objects being symlinked to project-objects/,
tell git to store any objects it fetches in project-objects/.

We do this by leveraging the GIT_OBJECT_DIRECTORY override.  This
has been in git forever, or at least since v1.7.2 which is what we
already hard require.  This tells git to save new objects to the
specified path no matter where it's being run otherwise.

We still otherwise run git in the project-specific dir so that it
can find the right set of refs that it wants to compare against,
including local refs.  For that reason, we also have to leverage
GIT_ALTERNATE_OBJECT_DIRECTORIES to tell git where to find objects
that are not in the upstream remote.  This way git doesn't blow up
when it can't find objects only associated with local commits.

As it stands right now, the practical result is the same: since we
symlink the project objects/ dir to the project-objects/ tree, the
default objects dir, the one we set $GIT_OBJECT_DIRECTORY to, and
the one we set $GIT_ALTERNATE_OBJECT_DIRECTORIES to are actually
all the same.  So this commit by itself should be safe.  But in a
follow up commit, we can replace the symlink with a separate dir
and git will keep working.

152032cca2 project: move --reference handling to project-objects
When using --reference, the path is written to objects/info/alternates.
The path is accessed inconsistently -- sometimes through projects/ (via
self.gitdir) and sometimes through project-objects/ (via self.objdir).
This works because projects/.../objects is a symlink to the objects dir
under project-objects/.  Change all accesses to go through self.objdir.
This will allow us to stop symlinking projects/.../objects without the
reference dir logic breaking.  The projects/ path is going to use its
alternates file for its own needs.

13576a8caf project: stop symlinking info dir under .git/
Unsharing this directory shouldn't be a problem.  The current repo code
treated it as a file, and while that's actually incorrect, files & dirs
are basically treated the same, so it's practically the same.

Let's enumerate each subpath since there aren't that many.

info/refs:
Only used when the project is exported over git dumb transports (i.e.
a http:// server).  Repo never does this, and it's extremely unlikely
any user has ever done this.  Plus, this proposal talks about unsharing
project refs, so this file should get unshared too.

info/grafts:
A user-configurable file that repo never touches.  Might be useful to
share across projects, but probably rarely (if ever) used by developers,
and forcing them to configure it for each project isn't that big of a
deal.

info/exclude:
info/attributes:
User-configurable files that repo never touches.  Doesn't seem like
most users ever touch these, and if they do, having them do it for
each shared project isn't a big deal.

info/sparse-checkout:
Repo doesn't use sparse checkouts, and it's extremely unlikely to even
work if a user tried doing something themselves.

41289c62b4 project: stop symlinking svn under .git/
This path only matters to users of `git svn` who manually run it in
local projects after they get a full repo client checkout.  With svn
usage falling in general, and with the fact that the source checkout
now symlinks its .git/ state to the internal projects/ path, we don't
need to manage this anymore.

It means the path won't be shared among multiple local projects that
have the same remote, but so it goes.  It was an optimization only,
not functionality required for correctness.  We want to simplify the
internals to stop messing with git state, and this particular path
doesn't seem worth the effort to maintain.

We don't undo any existing svn symlinks if they exist since repo does
not care about them, and their existence doesn't hurt anything.

code.  Throw it all away.  Do it as a separate commit to make the

2a089cfee4 project: migrate worktree .git/ dirs to symlinks
Historically we created a .git/ subdir in each source checkout and
symlinked individual files to the .repo/projects/ paths.  This layer
of indirection isn't actually needed: the .repo/projects/ paths are
guaranteed to only ever have a 1-to-1 mapping with the actual git
checkout.  So we don't need to worry about having files in .git/ be
isolated.

To that end, change how we manage the actual project checkouts from
a dir full of symlinks (and a few files) to a symlink to the internal
.repo/projects/ dir.  This makes the code simpler & faster.

The directory structure we have today is:
.repo/
  project-objects/chromiumos/third_party/kernel.git/
    <paths omitted as not relevant to this change>

9c1fc5bc5d sync: Handle tag ref in "upstream" field
repo sync only handles a git tag properly when it is in the "revision"
field. However, "revision locked manifests" (`repo manifest
--revision-as-HEAD`) specifies the tag in the "upstream" field. The
issue is that this tag is not fetched. Only the commit that the tag
points to is fetched. This cases issues as
self._CheckForImmutableRevision() runs and comes to the conclusion that
the tag was changed while in fact, it was just not fetched. This causes
a full sync.

File docs/manifest-format.md, section Element-project:
> Attribute upstream: Name of the Git ref in which a sha1 can be found.
Used when syncing a revision locked manifest in -c mode to avoid having
to sync the entire ref space. Project elements not setting their own
upstream will inherit this value.

333c0a499b project: init hooks in objdir only
objdir is the .repo/project-objects/ dir based on the remote path.
gitdir is the .repo/projects/ dir based on the local source checkout
path.  When we setup the gitdir, we symlink "hooks" to the one in the
objdir.  But when we go to initialize the hooks, we do it via gitdir.
There is a 1-to-many mapping from project-objects to projects, so
initializing via gitdir can be repetitive.  Collapse the hook init
logic to the objdir init path.

When a hard revision ID is provided in a regular project tag then the

is that if the revisionExpr is a commit, git-repo needs to update
refs/remotes/m/master with update-ref not symbolic-ref, as the latter
must refer to another ref, not to a specific commit.

8e983bbc0f Force a fetch when superproject has a newer SHA1 for remote branch.
For older git-repo versions, we might have only fetched the SHA1
revision that was provided by the project, but have remote branch left
intact as long as they exist. When the remote branch become stale,
some repo operations like rebase would fail, and repo sync would not
correct this situation.

Fix this by tightening the requirement to also require the superproject
provided SHA1 be an ancestor or equal to the tip-of-tree of the remote
branch.

0e776a5837 Fix an issue when syncing with --use-superproject and clone bundles.
It is possible that a clone bundle contained the object referenced by
the branch in the manifest and in the superproject, but not the branch
itself (for example, the branch may be newly created from an existing
branch, or is not vislble to the user downloading the clone bundle).

When --use-superproject is enabled, because we are overriding
revisionExpr with the SHA1 revision provided by the superproject, the
verification step would succeed, but because the expected branch do not
exist, it would confuse git-repo at a later time, as it is expecting the
remote branch to exist in the local clone.

In project.py, fix this by making SetRevisionId() to always remember
the actual branch name and verify it in _CheckForImmutableRevision()
so that we only skip the fetch step when both objects exists locally.

19e409c818 ssh: move proxy usage to the sync subcommand
The only time we really need ssh proxies is when we want to run many
connections and reuse them.  That only happens when running sync.
Every other command makes at most two connections, and even then it's
only one or none.  So the effort of setting up & tearing down ssh
proxies isn't worth it most of the time.

The big reason we want to move this logic to sync is that it's now
using multiprocessing for parallel work.  The current ssh proxy code
is all based on threads, which means none of the logic is working
correctly.  The current ssh design makes it hard to fix when all of
the state lives in the global/module scope.

So the first step to fixing this is top move the setup & teardown to
the one place that really needs it: sync.  No other commands will use
proxies anymore, just direct connections.

76844ba292 project: skip clone bundles when we've already initialized the object dir
The clone bundle logic assumes there is a one-to-one mapping between the
projects/ and project-objects/ trees.  When using shared projects (where
we checkout different branches from the same project), this would lead us
to fetching the same clone bundle multiple times.  Automatically skip the
clone bundle logic if the project-objects/ dir already exists.

84230009ee project: make diff tools synchronous
These are the only users in the tree that process the output as it's
produced.  All others capture all the output first and then process
the results.  However, these functions still don't fully return until
it's finished processing, and these funcs are in turn used in other
synchronous code paths.  So it's unclear whether anyone will notice
that it's slightly slower or less interactive.  Let's try it out and
see if users report issues.

This will allow us to simplify our custom GitCommand code and move it
over to Python's subprocess.run, and will help fix interleaved output
when running multiple commands in parallel (e.g. `repo diff -j8`).

0286e31ec7 Update _CheckForImmutableRevision to use git rev-list
_CheckForImmutableRevision is used to see if repo can
skip fetching a project, but 'git rev-parse' with partial
clone does a data fetch to accomplish this.

Changed to use: 'git rev-list -1 --missing=allow-any <SHA>^0' which
checks the local ref without fetching from the server first.

Bug: [google internal] b/179477822

Testing:
- Unit tests
- Verified init/sync working on aosp-master
- Verified wwith a pinned manifest that local ref check works (no fetch)

Added "--use-superporject" option to sync.py to fetch project SHAs from
superproject. If there are any missing projects in superprojects, it
prints the missing entries and exits. If there are no missing entries,
it will use SHAs from superproject to fetch the projects from git.

Tested the code with the following commands.

$ ./run_tests -v tests/test_git_superproject.py
$ ./run_tests -v

Tested the sync code by copying all the repo changes into my Android

local modification to the code to print the status,

1469c28ec3 project: detach HEAD in internal worktree checkout.
When checkout is done with Git worktrees then the HEAD in the
bare-git repositories point to the initialized default (e.g.
'refs/heads/master'). This default branch does not exist
locally and is not automatically created.
When a user now creates a branch in any git repository named
'master' then it is no longer possible to get rid of this branch,
neither is it possible to switch to another branch and switch
back to this master branch. Git concludes the 'master' branch is
already checked out (in the bare Git) and that results in a
lockdown of this master branch.

To repoduce this issue, run these commands in a repo tree
checked out with --worktree:
- git checkout master # assuming the remote repo has a master branch,
                      # a local tracking branch master is created here
- git checkout -b temp
- git checkout master # This one now fails
- git branch -d master # fails too
The failure is caused by Git assuming the master branch is checked out
by the bare git repository since HEAD is pointing towards it.

To workaround this, we always detach HEAD in the bare-git when
syncing.  We don't need it to point to a ref in general, but we
would like it to be valid so git tools "just work" if they're run
in here.

"master" already.  For projects moving to "main", it means we'll use

For repositories that never set up a default HEAD, we should still use
the historical "master" default.

21b7fbe14d project: fix m/ pseudo ref handling with git worktrees
Since most ref namespaces are shared among all worktrees, trying to
set the pseudo m/<branch> in the common git repo ends up clobbering
each other when using shared checkouts.  For example, in CrOS:
  <project path="src/third_party/kernel/v3.8"
           name="chromiumos/third_party/kernel"
           revision="refs/heads/chromeos-3.8" />
  <project path="src/third_party/kernel/v3.10"
           name="chromiumos/third_party/kernel"
           revision="refs/heads/chromeos-3.10" />

Trying to set m/master in chromiumos/third_party/kernel.git/ will
keep clobbering the other.

Instead, when using git worktrees, lets set the m/ pseudo ref to
point into the refs/worktree/ namespace which is unique to each
git worktree.  So we have in the common dir:
  chromiumos/third_party/kernel.git/:
    refs/remotes/m/master:
      ref: refs/worktree/m/master
And then in each worktree we point refs/worktree/m/master to the
respective manifest revision expression.  Now people can use the
m/master in each git worktree and have it resolve to the right
commit for that worktree.

75264789c0 project: fix worktree init under Windows
Git likes to create .git files with read-only permissions which makes
it difficult to open+truncate+write in situ under Windows.  Delete it
before we write the file content to workaround.

7951e14385 project: fallback to hardlinks with git hooks
Windows requires Administrator access to create symlinks.  We can
mitigate this a bit by falling back to hardlinks as those may be
created by any user on the system.  Do this with the git hooks as
these are supposed to be internal only and people shouldn't be
modifying them.  If they do, they'll have to delink first.  This
seems worth it to allow repo usage without extra privileges.

d9254599f9 manifest/tests: get them passing under Windows
We also need to check more things in the manifest/project handlers,
and use platform_utils in a few places to address Windows behavior.

Drop Python 2.7 from Windows testing as it definitely doesn't work
and we won't be fixing it.

746e7f664e project: unify StartBranch flows behind git-update-ref
We're using this for git worktrees because it handles the .git file
format, but it should work for all flows.  Unify to simplify.  This
also fixes the worktree logic which duplicated .git/config settings.

c0d1866b35 project/sync: move DeleteProject helper to Project
Since deleting a source checkout involves a good bit of internal
knowledge of .repo/, move the DeleteProject helper out of the sync
code and into the Project class itself.  This allows us to add git
worktree support to it so we can unlock/unlink project checkouts.

f81c72ed77 project: set core.repositoryFormatVersion=1 when using extensions
When using extensions, make sure we set the git repo format version
so git knows to check the extension compatibility.  We can add a
helper to the Project API to simplify this and make it foolproof.

979d5bdc3e add experimental git worktree support
This provides initial support for using git worktrees internally
instead of our own ad-hoc symlink tree.  It's been lightly tested
which is why it's not currently exposed via --help.

When people opt-in to worktrees in an existing repo client checkout,
no projects are migrated.  Instead, only new projects will use the
worktree method.  This allows for limited testing/opting in without
having to completely blow things away or get a second checkout.
