15e807cf3c forall: improve pool logic
Use a pool contextmanager to take care of the messy details like
properly cleaning it up when aborting.

7c871163c8 status: improve parallel execution stability
The status command runs a bunch of jobs in parallel, and each one
is responsible for writing to stdout directly.  When running many
noisy jobs in parallel, output can get intermingled.  Pass down a
StringIO buffer for writing to so we can return the entire output
as a string so the main job can handle displaying it.  This fixes
interleaved output as well as making the output stable: we always
display results in the same project order now.  By switching from
map to imap, this ends up not really adding any overhead.

6a2400a4d0 command: unify --job option & default values
Extend the Command class to support adding the --jobs option to the
parser if the command declares it supports running in parallel.  Also
pull the default value used for the number of local jobs into the
command module so local commands can share it.

c5bbea8db3 git_command: make execution synchronous
Every use of GitCommand in the tree just calls Wait as soon as it's
instantiated.  Move the bulk of the logic into the init path to make
the call synchronous to simplify.  We'll cleanup the users of the
Wait API to follup commits -- having this split makes it easier to
track down regressions.

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`).

21dce3d8b3 init: added --use-superproject option to clone superproject.
Added --no-use-superproject to repo and init.py to disable use of
manifest superprojects.

Replaced the term "sha" with "commit id".

Added _GetBranch method to Superproject object.

Moved shared code between init and sync into SyncSuperproject function.
This function either does git clone or git fetch. If git fetch fails
it does git clone.

Changed Superproject constructor to accept manifest, repodir and branch
to avoid passing them to multiple functions as argument.

Changed functions that were raising exceptions to return either True
or False.

Saved the --use-superproject option in config as repo.superproject.
Updated internal-fs-layout.md document.

Updated the tests to work with the new API changes in Superproject.

Performance for the first time sync has improved from 20 minutes to
around 15 minutes.

Tested the code with the following commands.

$ ./run_tests -v

Tested the sync code by using repo_dev alias and pointing to this CL.

$ repo init took around 20 seconds longer because of cloning of superproject.

$ time repo_dev init -u sso://android.git.corp.google.com/platform/manifest -b master --partial-clone --clone-filter=blob:limit=10M --repo-rev=main --use-superproject
...
real	0m35.919s
user	0m21.947s
sys	0m8.977s

First run
$ time repo sync --use-superproject
...
real	16m41.982s
user	100m6.916s
sys	19m18.753s

No difference in repo sync time after the first run.

does Clone if Fetch fails.

1fd7bc2438 sync: superproject performance changes.
After updating all project’s revsionIds with the SHAs from superproject,
write the updated manifest into superproject_override.xml file. Reload
that file for future Reloads. This file is created in exp-superproject
directory.

Moved most of the code that is superproject specific into
git_superproject.py and wrote test code.

If git pull fails, did a git clone of the superproject.

We saw performance gains for consecutive repo sync's. The time to sync
went down from around 120 secs to 40 secs when repo sync is executed
consecutively.

e5670c8812 launcher: add a requirements framework to declare version dependencies
Currently we don't have a way for the checked out repo version to
declare the version of tools it needs before we start running it.
For somethings, like git, it's not a big deal as it can handle all
the asserts itself.  But for things like Python, it's impossible
to reliably check before executing.

We're in this state now:
- we've been allowing Python 3.4, so the launcher accepts it
- the repo codebase starts using Python 3.6 features
- launcher tries to import us but hits syntax errors
- user is left confused and assuming new repo is broken because
  they're seeing syntax errors

This scenario is playing out with old launchers that still accept
Python 2, and will continue to play out as time goes on and we want
to require newer versions of Python 3.

Lets create a JSON file to declare all these system requirements.
That file format is extremely stable, so loading & parsing from
even ancient versions of Python shouldn't be a problem.  Then the
launcher can read these settings and check the system state before
attempting to execute any code.  If the tools are too old, it can
clearly diagnose & display information to the user as to the real
problem (and not emit tracebacks or syntax errors).

We have a couple of different tool version checks already (git,
python, ssh) and can harmonize them in a single place.

This also allows us to assert a reverse dependency if the need
ever comes up: force the user to upgrade their `repo` launcher
before we'll let them run us.  Even though the launcher warns
whenever a newer release is available, some users seem to ignore
that, or they don't use repo that often (on the scale of years),
and their upgrade jump is so dramatic that they fall back into
the syntax error pit.

Hopefully by the end of the year we can assume enough people
have upgraded their launcher such that we can delete all of the
duplicate version checks in the codebase.  But until then, we'll
keep them to maintain coverage.

At most one superproject may be specified. It will be used
to specify the URL of superproject.

It would have 3 attributes: remote, name, and default.
Only "name" is required while the others have reasonable defaults.

<remote name="superproject-url" review="<url>" />
<superproject remote="superproject-url" name="platform/superproject"/>

TODO: This CL only implements the parsing logic and further work
will be in followup CLs.

128f34e874 main: require Python 3.5 now
We've been warning about Python 3.4 for almost a year.  This drops
support for these systems:
* Ubuntu Trusty: released Apr 2014, EOL Apr 2022
* Debian Jessie: released Apr 2015, EOL Jun 2020

So the min required distros would now be:
* Ubuntu Xenial: released Sep 2015 w/Python 3.5
* Debian Stretch: released Jun 2017 w/Python 3.6

I don't think we're quite ready to drop Python 3.5 which would affect
Ubuntu Xenial -- we'd have to update to Ubuntu Bionic from Apr 2018.
Let's see how much the community reacts to loss of Python 3.4 first.

2) Specify path via --git_trace2_event_log option

A unique logfile name is generated per repo execution (based on the repo session-id).

Testing:
1) Verified git config 'trace2.eventtarget' and flag enable logging.
2) Verified version/start/end events are expected format:

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.

8add62325d Add parallelism to 'branches' command
Spread the operation of querying which local branches exist across a
pool of processes and build the name map of projects -> branches as
these tasks finish rather than blocking on the entire query. The search
operations are submitted in batches to reduce the overhead of interprocess
communication. The `chunksize` argument used to control this batch size
was selected by incrementing through powers of two until it stopped being
faster.

5e2f32fe13 init: reset hard to --repo-rev
When updating the tracking ref to whatever the user requested,
make sure we reset state completely rather than trying to update
the ref to it.  This avoids confusing git as to the current state
of the tree, and is more inline with user intentions: if they made
a local change to the checkout, but ran repo init with a specific
rev, we shouldn't stay wedged forever until they manually clean it
all up.
