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.

2345906d04 project: stop symlinking description file under .git/
Nothing uses this path.  It’s only for exporting git dirs e.g. for
online gitweb use which probably no one does.  It is not the same
description file as exists on servers we cloned from.  Leaving it
as the default plain text file will simplify code.

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

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.

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:

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.

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.

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.

While this provides a way to undo earlier command line options (e.g.
`repo sync --tags --no-tags`) which can be helpful for scripting &

7356114d90 add --no-current-branch option to invert --current-branch
For most commands, this is more about providing a way to undo earlier
command line options (e.g. `repo info -c --no-current-branch`) which
can be helpful for scripting & automation.  But for the sync command,
this is helpful to undo the setting that exists in the manifest itself.

With this in place, tweak the sync current_branch_only logic to only
apply the manifest settings when the user hasn't specified a command
line option.

aabf79d3f0 sync: Fix a corner case when both superproject and depth used.
When depth is used, we would fetch only SHA1 when superproject is
used, as the result, only the manifest branch is being recorded,
and commands like repo start would fail.

Fix this by saving the upstream branch value in the overlay
manifest and add the upstream branch to fetch list.

6823bc269d sync: cleanup sleep+retry logic a bit
Make sure we print a message whenever we retry so it's clear to the
user why repo is pausing for a long time, and why repo might have
passed even though it displayed some errors earlier.

Also unify the sleep logic so we don't have two independent methods.
This makes it easier to reason about.

Also don't sleep if we're in the last iteration of the for loop.  It
doesn't make sense to and needlessly slows things down when there are
real errors.

If the current project doesn't have any local branches, then there's

it avoids checking repository validity.  Since we aren't going to do

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`).
