Lots of places suggest using the -c or --current-branch option to the repo command to reduce the amount of code downloaded. However, it no longer seems to be available:

repo --time -c -j2 sync
Usage: repo [-p|--paginate|--no-pager] COMMAND [ARGS]

main.py: error: no such option: -c

Is there an alternative switch now or has the functionality been completely removed?

Can I get an old version of the repo wrapper from somewhere that still has the -c switch and use that?

Is there a problem with using -c?

My use case is to get a specific branch of CyanogenMod and build a ROM for my phone.

EDIT: Interestingly, the sync.py appears to have the option in it.

grep -a2 current-branch .repo/repo/subcmds/sync.py
of a project from server.

The -c/--current-branch option can be used to only fetch objects that
are on the branch specified by a project's revision.

                 help='detach projects back to manifest revision')
    p.add_option('-c', '--current-branch',
                 dest='current_branch_only', action='store_true',
                 help='fetch only current branch from server')

Maybe attribute upstream of project element in manifest.xml is a solution for your question.

According to the document of manifest file

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.

As noted in the edit to the question, the switch is still available.

The confusion has come from the fact that there are actually 2 python scripts in use in repo --time -c -j2 sync.

repo is one script, it then sends parameters to the sync script.

-c and -j are parameters to the sync script and --time is a parameter to the repo script.

Therefore, the command should be

repo --time sync -c -j2
