git-p4 - Perforce <-> Git converter using git-fast-import
|
|
|
|
Usage
|
|
=====
|
|
|
|
git-p4 supports two main modes: Importing from Perforce to a Git repository is
|
|
done using "git-p4 sync". Submitting changes from Git back to Perforce is
|
|
done using "git-p4 submit".
|
|
|
|
Importing
|
|
=========
|
|
|
|
The procedure is simple:
|
|
|
|
mkdir repo-git
|
|
cd repo-git
|
|
git init
|
|
git-p4 sync //path/in/your/perforce/depot
|
|
|
|
This will import the current head revision of the specified depot path into a
|
|
"p4" branch of your git repository. You can use the --branch=mybranch option
|
|
to use a different branch.
|
|
|
|
If you want to import the entire history of a given depot path just use
|
|
|
|
git-p4 sync //path/in/depot@all
|
|
|
|
To achieve optimal compression you may want to run 'git repack -a -d -f' after
|
|
a big import. This may take a while.
|
|
|
|
Support for Perforce integrations is still work in progress. Don't bother
|
|
trying it unless you want to hack on it :)
|
|
|
|
|
|
Incremental Imports
|
|
===================
|
|
|
|
After an initial import you can easily synchronize your git repository with
|
|
newer changes from the Perforce depot by just calling
|
|
|
|
git-p4 sync
|
|
|
|
in your git repository.
|
|
|
|
It is recommended to run 'git repack -a -d -f' from time to time when using
|
|
incremental imports to optimally combine the individual git packs that each
|
|
incremental import creates through the use of git-fast-import.
|
|
|
|
Submitting
|
|
==========
|
|
|
|
git-p4 has support for submitting changes from a git repository back to the
|
|
Perforce depot. This requires a Perforce checkout separate to your git
|
|
repository. To submit all changes that are in the current git branch but not in
|
|
the "p4" branch (or "origin" if "p4" doesn't exist) simply call
|
|
|
|
git-p4 submit
|
|
|
|
in your git repository. If you want to submit changes in a specific branch that
|
|
is not your current git branch you can also pass that as an argument:
|
|
|
|
git-p4 submit mytopicbranch
|
|
|
|
You can override the reference branch with the --origin=mysourcebranch option.
|
|
|
|
If a submit fails you may have to "p4 resolve" and submit manually. You can
|
|
continue importing the remaining changes with
|
|
|
|
git-p4 submit --continue
|
|
|
|
After submitting you should sync your perforce import branch ("p4" or "origin")
|
|
from Perforce using git-p4's sync command.
