Submitting changes from Git back to Perforce is +done using "git-p4.py submit". + +Importing +========= + +The procedure is simple: + + mkdir repo-git + cd repo-git + git init + git-p4.py sync //path/in/your/perforce/depot + +This will import the current head revision of the specified depot path into the +master branch of your git repository. You can use the --branch=mybranch option +to let git-p4 import from Perforce into a git branch of your choice. + +If you want to import the entire history of a given depot path just use + + git-p4.py sync //path/in/depot@all + + +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.p4 sync + +in your git repository. git-p4 stores the depot path of the original import in +the .git/config file and remembers the last imported p4 revision as a git tag +called p4/ . + +Submitting +========== + +git-p4 has EXPERIMENTAL support for submitting changes from a git repository +back to a Perforce depot. This requires a Perforce checkout separate to your +git repository. This is the basic procedure: + + cd path/to/your/perforce/checkout + git-p4.py submit --git-dir=/path/to/your/git/repository + +This will create a temporary git branch, use git-rev-list to find out which git +commits are in your current branch but not in the "origin" branch. You can +override the name of the "origin" branch by using the --origin=mybranch option. +The "origin" branch has to be the branch populated with git-p4's sync +operation. + +After some preparations (which might take a while) git-p4 enters a loop where +it will first show a Perforce submit template and a diff of the change to +apply. After quitting the pager with 'q' git-p4 asks for confirmation for +issuing the "p4 submit" command and also gives you the option of editing the +submit template using "e". + +If a submit fails you may have to "p4 resolve" and submit manually. You can +continue importing the remaining changes with + + git-p4.py submit --git-dir=/path/to/your/git/repository --continue + +After submitting you should sync your origin branch from Perforce using +git-p4's sync command. + -- 2.26.2
