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.

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.

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.

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.

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.

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.

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.

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.

When intializing a new repo with the --reference option on Windows 10
the objects/info/alternates in each git repository is created with
Windows line endings (\r\n), leading to the following error:
error: object directory C:/<PATH_TO_MIRROR>/<REPO_NAME>.git/objects?

This can be fixed by simply using unix line endings on both

Instead of hardcoding "master" as our default, use the remote server's
default branch instead. For most people, this should be the same as
"master" already. For projects moving to "main", it means we'll use
the new name automatically rather than forcing people to use -b main.
For repositories that never set up a default HEAD, we should still use
the historical "master" default.

The intention of the check is to verify whether the target

This has the side effect that a target file that does not
exist at the moment of the check is considered to contain a

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.

We have a few files that we optionally symlink from the work tree
.git/ to the .repo/projects/ path. If they don't exist when we
first initialize, then we skip creating symlinks. If the files
are created later on under the work tree .git/, repo gets upset.
This can happen with the packed-refs file: if we don't have any
packed refs initially, we don't symlink it. But if git tries to
pack refs later on and creates the file, the project gets wedged.
We could create an empty file initially and then symlink it, but
for some files, it's not clear we want to always do that (e.g.
the .git/shallow setting). Instead, lets make handling of these
paths more dynamic. If they show up later on in the work tree
.git/ only, we'll take care of relocating & symlinking. This
also makes repo a little more robust and autorecovers incase a
path goes missing in one of the dirs.
Ideally we wouldn't monkey around at all here, but considering
the only option we give to users currently is to blow things
away with --force-sync, this seems a bit better.

Add a helper function to unify the duplication of finding the full
path to the symbolic HEAD ref. This makes it easy to handle git
worktrees where .git is a file rather than a dir/symlink.

Reject paths in <copyfile> & <linkfile> that try to use symlinks or
non-file or non-dirs.
We don't fully validate <linkfile> when src is a glob as it's a bit
complicated -- any component in the src could be the glob. We make
sure the destination is a directory, and that any paths in that dir
are created as symlinks. So while this can be used to read any path,
it can't be abused to write to any paths.

Before a2cd6aeae8, "repo mirror with --current-branch" fetches git data
using command
git fetch --progress --update-head-ok cros --tags
No refspec is specified, thus it fetches default refspec, which is +refs/heads/*:refs/heads/*
After a2cd6aeae8, the fetch command became
git fetch --progress --update-head-ok cros --tags +refs/tags/*:refs/tags/*
It did not only add tags refspec, but also suppressed the fetching of default refspec.
In other words, repo mirrors doesn't work if current_branch_only=True.
This CL explicitly adds the default refspec to command line if none is
specified.

Series of steps:
* Create a local "b1" branch with `repo start b1` that tracks a remote
branch (totally fine)
* Manually create a local "b2" branch with `git branch --track b1 b2`
that tracks the local "b1" (uh-oh...)
* Delete the local "b1" branch manually or via `repo prune` (....)
* Try to process the "b2" branch with `repo prune`
Since b2 tracks a branch that no longer exists, everything blows up
at this point as we try to probe the non-existent ref. Instead, we
should flag this as unknown and leave it up to the user to resolve.
This probably could come up if a local branch was tracking a remote
branch that was deleted from the server, and users ran something like
`repo sync --prune` which cleaned up the remote refs.

If the local branch changed state since its last upload, the data
cached in .git/config related to the last uploaded CL might not be
that relevant. If we're able to fast forward merge to the latest
tree state, then let's do that. This would be akin to checking
out a detached head before syncing where we already switch state.
If we aren't able to fast forward merge, then it's not a big deal
as we'll continue on to the existing branch checking logic.
This would be easy to reproduce by doing something like:
$ repo start foo .
$ git revert HEAD
$ repo upload --cbr .
$ git reset --hard HEAD^
<CL is merged>
$ repo sync .
<we can fast forward>

If you run `repo sync -l foo` without first `repo sync -n foo`,
repo sets up an invalid gitdir tree that gets wedged and requires
manual recovery. Add a sanity check to abort cleanly first.

Hitting Ctrl-C in the middle of this func will leave the .git in a
bad state that requires manual recovery. The code tries to catch
all exceptions and recover by deleting the incomplete .git dir, but
it omits KeyboardInterrupt which Exception misses.
We could add that to the recovery path, but we can make this more
robust with a different approach: set up everything in .git.tmp/
and only move it to .git/ once we've fully initialized it.

When displaying progress bars, we use \r to reset the cursor to the
start of the line before showing the new update. This assumes the
new line will fully erase whatever was displayed there previously.
The "done" codepath tries to handle this by including a few extra
spaces at the end of the message to "white out" what was there.
Lets replace that hack with the standard ECMA escape sequence that
clears the current line completely. This is the CSI "erase in line"
sequence that the terminal will use to delete all content. The \r
is still needed to move the cursor to the start of the line. Using
this sequence should be OK since we're already assuming the terminal
is ECMA compliant with our use of coloring sequences. We also put
the \r after the CSI sequence on the off chance the terminal can't
process it and displays a few bytes of garbage.
The other improvement is to the syncbuffer API. When it dumps its
status information, it almost always comes after a progress bar
update which leads to confusing comingled output. Something like:
Fetching projects: 100% (2/2) error: src/platform2/: branch ...
Since the progress bar is "throw away", have the syncbuffer reset
the current output to the start of the line before showing whatever
messages it has queued.
