2f3c3316e4 Update revisionId if required when using extend-project
When a hard revision ID is provided in a regular project tag then the
revisionId is updated as well if it is a commit hash.  The difference
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.

9d96f58f5f make file removal a bit more robust
Some of the file removal calls are subject to race conditions (if
something else deletes the file), so extend our remove API to have
an option to ignore ENOENT errors.  Then update a bunch of random
call sites to use this new functionality.

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.

b16b9d26bd project: fix error display when output_redir is disabled
We always pass in output_redir when syncing, but that's the common case:
there are a few situations (like `repo init`) where we don't pass in a
buffer, and if any errors show up in that case, we'd crash.  Rely on the
print function to handle this logic for us.

339f2df1dd ssh: rewrite proxy management for multiprocessing usage
We changed sync to use multiprocessing for parallel work.  This broke
the ssh proxy code as it's all based on threads.  Rewrite the logic to
be multiprocessing safe.

Now instead of the module acting as a stateful object, callers have to
instantiate a new ProxyManager class that holds all the state, an pass
that down to any users.

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.

command line options (e.g. `repo info -c --no-current-branch`) which

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

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.

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`).

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

Tested the sync code by copying all the repo changes into my Android
AOSP checkout and adding <superporject> tag to default.xml. With
local modification to the code to print the status,

.../WORKING_DIRECTORY$ repo sync --use-superproject
repo: executing 'git clone' url: sso://android/platform/superproject
repo: executing 'git ls-tree'
Success: []

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.

When intializing a new repo with the --reference option on Windows 10

error: object directory C:/<PATH_TO_MIRROR>/<REPO_NAME>.git/objects?

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

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.

that if the file is non-existent - it contains a wild card.
This has the side effect that a target file that does not
exist at the moment of the check is considered to contain a
wild card, this leads itself to softlink not being created.

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.

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.

31990f0097 project: move successful fetch output behind verbose
Syncing projects works fine the majority of the time.  So rather than
dump all of that noisy output to stdout, lets capture it and only show
when things fail or in verbose mode.  This tidies up the default `repo
sync` output.

ed4f2113d2 project: make syncing a little more self-healing
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.

Reject paths in <copyfile> & <linkfile> that try to use symlinks or

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.

6856f98467 Fix repo mirror with --current-branch
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.

6da17751ca prune: handle branches that track missing branches
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.

2ba5a1e963 sync: try to fast forward merge branches before checking published state
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>

70d861fa29 sync: improve output with intermingled progress bars and status
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.

600f49278a project: fix encoding handling with git commands
The GitCommand Wait helper takes care of decoding bytes to strings
for us.  That means we don't have to decode stdout ourselves which
is what our local rev list, ls-remote, and generic get_attr helpers
were doing.

If we don't use Wait though to capture the output but instead go
directly to the subprocess stdout, we do have to handle decoding
ourselves.  This is what the diff helpers were doing.

f7c51606f0 hooks: support external hooks running different Python version
As we convert repo to support Python 3, the version of Python that we
use might not be the version that repo hooks users have written for.
Since repo upgrades are not immediate, and not easily under direct
control of end users (relative to the projects maintaining the hook
code), allow hook authors to declare the version of Python that they
want to use.

Now repo will read the shebang from the hook script and compare it
against the version of Python repo itself is running under.  If they
differ, we'll try to execute a separate instance of Python and have
it load & execute the hook.  If things are compatible, then we still
use the inprocess execution logic that we have today.

This allows repo hook users to upgrade on their own schedule (they
could even upgrade to Python 3 ahead of us) without having to worry
about their supported version being exactly in sync with repo's.

Different from restricting clone-depth, the user will have full access

Currently we read the binary stream from the subprocess code directly
before waiting for it to finish, but there's no need to do so as we
aren't streaming the output to the user.  This also means we pass up
binary data to the caller as we don't go through GitCommand's internal
logic which decodes the stream as utf-8.

Simplify the code by calling Wait first, then splitting the entire
captured output in one line.

c5b0e23490 project: Set config option to skip lfs process filter
During sync, repo runs `git read-tree --reset -u -v HEAD` which causes
git-lfs's smudge filter to run, which fails because git-lfs does not
work with bare repositories.

This was fixed in I091ff37998131e2e6bbc59aa37ee352fe12d7fcd to
automatically disable this smudge filter. However, later versions of
Git (2.11.0) introduced a new filter protocol [1], to avoid spawning
a new command for each filtered file. This was implemented in Git-LFS
1.5.0 [2].

This patch fixes the issue by setting the git lfs process filter, in
addition to the smudge filter. For any projects that have LFS objects,
`git lfs pull` must still be executed manually afterwards.

If a tag is rewritten on the server (which is bad), trying to recover
locally with `repo sync --force-sync` doesn't actually work.  People
have to manually delete things themselves to fix syncing.  While tags
should never be rewritten in practice, allow users to easily recover
from broken servers.

project.py:Project.UploadForReview method is modified to accept a

disable sending emails completely.

Default repo upload behavior is not being changed.

     patches uploaded without these command line options still trigger
     email notifications.

09f0abb0ef init: --dissociate option to copy objects borrowed with --reference
"repo init --reference" has two purposes: to decrease bandwidth used
at clone time, and to decrease disk usage afterward, by using the
reference repositories as an alternate store of objects even after
the clone. The downside is that it makes the borrowing repositories
dependent on the reference repositories, so it is easy to end up
with missing objects by mistake after a cleanup operation like "git
gc".

To prevent that, v2.3.0-rc0~30^2 (clone: --dissociate option to mark
that reference is only temporary, 2014-10-14), "git clone" gained a
--dissociate option that makes --reference reuse objects from the
reference repository at clone time but copy them over instead of
using the reference as an alternate. This is more straightforward to
use than plain --reference, at the cost of higher disk usage.

Introduce a --dissociate to "repo init" that brings the same benefits
to repo. The option is simply passed on to "git clone".

d5cec5e752 Add support for creating symbolic links on Windows
Replace all calls to os.symlink with platform_utils.symlink.

The Windows implementation calls into the CreateSymbolicLinkW Win32
API, as os.symlink is not supported.

Separate the Win32 API definitions into a separate module
platform_utils_win32 for clarity.

e4e94d26ae init: add --submodules to sync manifest submodules
repo sync can sync submodules via the --fetch-submodules option.
However, if the manifest repo has submodules, those will not be synced.
Having submodules in the manifest repo -- while not commonly done -- can
be useful for inheriting a manifest from another project using <include>
and layering changes on top of it.  In this way, you can avoid having to
deal with merge conflicts between your own manifests and the other
project's manifests (for example, if you're managing an Android fork).

Add a --submodule option to init that automatically syncs the submodules
in the manifest repo whenever the manifest repo changes.

6c5944606a Fix checkout error when depth passed to repo init and revision is a sha1
Currently, if direct fetch of a sha1 is not supported by git server and
depth option is used, we fallback on syncing the upstream branch by
ignoring depth option.

This fallback doesn't work in next 2 cases:
(1) upstream attribute is not specified in manifest
(2) depth option is passed to repo init command
    (not with clone-depth attribute in manifest)

This commit do the following:
- fixes (1) by updating condition used to apply fallback
  first we retry with depth set to None, then by syncing all branches
- fixes (2) by passing depth as argument of _RemoteFetch() method
  thus, its value is not set again to depth value passed to repo init
  command when applying fallback

ec287902e6 _CheckDirReference: log actual error before suggesting --force-sync
A recent backward incompatible change created confusion and loss of
productivity and highlighted the very limited amount of information
provided when repo sync fails; merely recommending to --force-sync
and blow-up git repos without any hint as to why. The addition of
this basic _error(...) call would have provided a clue and will in
the future.

4d5bb68d58 status: add -q/--quiet option
The --quiet option reduces the output to just
a list of projects with modified workspaces (and
orphans if -o is specified)

A common use case is when performing a full-workspace
merge.  The integrator will kick-off a merge via:

    repo forall -c git merge <some tag>

And then produce a short list of conflicted projects via:

    repo status -q

The integrator can then iteratively fix and clean up all conficted
components.  The merge is complete when:

    repo status -q

    returns no output.
