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 |
|
========= |
|
|
|
You can simply start with |
|
|
|
git-p4 clone //depot/path/project |
|
|
|
or |
|
|
|
git-p4 clone //depot/path/project myproject |
|
|
|
This will create an empty git repository in a subdirectory called "project" (or |
|
"myproject" with the second command), import the head revision from the |
|
specified perforce path into a git "p4" branch, create a master branch off it |
|
and check it out. If you want the entire history (not just the head revision) then |
|
you can simply append a "@all" to the depot path: |
|
|
|
git-p4 clone //depot/project/main@all myproject |
|
|
|
|
|
|
|
If you want more control you can also use the git-p4 sync command directly: |
|
|
|
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 :) |
|
|
|
For convenience there's also the git-p4 clone command that works similar to |
|
git-clone and combines the creation of the git repository with the the initial |
|
import and the branch setup |
|
|
|
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. By default the "p4" branch is updated. |
|
|
|
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. |
|
|
|
Updating |
|
======== |
|
|
|
A common working pattern is to fetch the latest changes from the Perforce depot |
|
and merge them with local uncommitted changes. The recommended way is to use |
|
git's rebase mechanism to preserve linear history. git-p4 provides a convenient |
|
|
|
git-p4 rebase |
|
|
|
command that calls git-p4 sync followed by git rebase to rebase the current |
|
working branch. |
|
|
|
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.
