8367096d02 superproject: Added --depth=1 argument to git fetch command.
Tested the code with the following commands.

$ ./run_tests -v

Without --depth

$ time repo_dev init -u sso://googleplex-android.git.corp.google.com/platform/manifest -b master --repo-rev=main --use-superproject
real    6m48.086s
user    3m27.281s
sys     1m1.386s

With --depth=1
$ time repo_dev init -u sso://googleplex-android.git.corp.google.com/platform/manifest -b master --repo-rev=main --use-superproject

real    2m49.637s
user    2m51.458s
sys     0m39.108s

From dwillemsen@:
 "For me it's the difference between 9m28s using the current code and
  16s using --depth=1 while fetching the superproject."

080877e413 superproject: pass groups to ToXml method.
Added the following methods to XmlManifest class.
+ GetDefaultGroupsStr() - return 'default,platform-' + platform.system().lower()
+ GetGroupsStr() - Same as gitc_utils.py's _manifest_groups func.

+ Replaced gitc_utils.py's_manifest_groups calls with GetGroupsStr.
+ Used the above methods to get groups in command.py::GetProjects
  and part of init.py.

TODO: clean up these funcs to take structured group data more instead
      of passing strings around everywhere that need parsing.

Tested the code with the following commands.

$ ./run_tests -v

Tested the sync code by using repo_dev alias and pointing to this CL
and verified prebuilts/fullsdk-linux directory has all the folders.

Tested repo init and repo sync with --use-superproject and without
--use-superproject argument.

$ repo_dev init -u sso://android.git.corp.google.com/platform/manifest -b androidx-main  --partial-clone --clone-filter=blob:limit=10M --repo-rev=main --use-superproject

$ repo_dev sync -c -j32

ef99ec07b4 superproject: Display status messages during repo init/sync.
Superproject objects accept the optional argument “quiet”.
The following progress messages are displayed if quiet is false.

Displayed the following message whenever we find we have to make a new
folder (aka new remote), because if you started with repo init android
and later do googleplex-android that is when it will be slow.

"<location>: Performing initial setup for superproject; this might take
several minutes.".

After fetch completion, added the following notification:
"<location>: Initial setup for superproject completed."

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_dev init -u persistent-https://googleplex-android.git.corp.google.com/platform/manifest -b rvc-dev  --partial-clone --clone-filter=blob:limit=10M --repo-rev=main  --use-superproject

ceba2ddc13 sync: superproject - support for switching hosts and switching branches.
+ superproject will be fetched into a directory with the name
  “<remote name>-superproject.git” instead of the current
  “superproject.git” folder.

+ Deleted  _Clone method and added _Init method.

+ _Init method will do “git init --bare <remote>-superproject.git”.
  It will create the folder and set up a bare repository in
  <remote>-superproject.git folder.

+ _Fetch method, will pass <remote url>, <branch> arguments.
  Moved the --filter argument from “git clone” to “git fetch”.
  _Fetch method will execute the following command to fetch
  superproject. Added --no-tags argument.

  master:  git fetch <remote url> --force --no-tags --filter blob:none
  branch:  git fetch <remote url> --force --no-tags --filter blob:none \
           <branch>:<branch>

+ Performance improvements for aosp-master
  ++ repo init performance improved from 35 seconds to 17 seconds.
  ++ repo init --use-superproject is around 5 to 7 secsonds slower.
  ++ repo sync --use-superproject is around 3 to 4 minutes faster.

$ ./run_tests -v

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.

8d43dea6ea sync: pass --bare option when doing git clone of superproject.
Changed "git pull" to "git fetch" as we are using --bare option. Used the
following command to fetch:
  git fetch origin +refs/heads/*:refs/heads/* --prune

Pass --branch argument to Superproject's UpdateProjectsRevisionId function.

Returned False/None when directories don't exist instead of raise
GitError exception from _Fetch and _LsTree functions. The caller of Fetch
does Clone if Fetch fails.

Tested the code with the following commands.

$ ./run_tests -v

Tested the init and sync code by copying all the repo changes into my Android
AOSP checkout and running repo sync with --use-superproject option.

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.

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
AOSP checkout and doing a repo sync --use-superproject twice.

First run
$ time repo sync --use-superproject
...
real	21m3.745s
user	97m59.380s
sys	19m11.286s

After two consecutive sync runs
$ time repo sync -c -j8 --use-superproject

user	0m29.937s

ef267722f8 sync: Added --filter=blob:none for git clone of superproject.
+ This is without --depth option. This is done for reachability.
  Server doesn't know what you know about in the history so it always

  If we have the full history it can send you incremental update history
  which is very small and fast.
