+ 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.
Tested the code with the following commands.
$ ./run_tests -v
Tested the sync code by using repo_dev alias and pointing to this CL.
$ 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
