1git-p4.py - Perforce <-> Git converter using git-fast-import 2 3Usage 4===== 5 6git-p4 supports two main modes: Importing from Perforce to a Git repository is 7done using "git-p4.py sync". Submitting changes from Git back to Perforce is 8done using "git-p4.py submit". 9 10Importing 11========= 12 13The procedure is simple: 14 15 mkdir repo-git 16 cd repo-git 17 git init 18 git-p4.py sync //path/in/your/perforce/depot 19 20This will import the current head revision of the specified depot path into the 21master branch of your git repository. You can use the --branch=mybranch option 22to let git-p4 import from Perforce into a git branch of your choice. 23 24If you want to import the entire history of a given depot path just use 25 26 git-p4.py sync //path/in/depot@all 27 28 29Support for Perforce integrations is still work in progress. Don't bother 30trying it unless you want to hack on it :) 31 32 33Incremental Imports 34=================== 35 36After an initial import you can easily synchronize your git repository with 37newer changes from the Perforce depot by just calling 38 39 git-p4.p4 sync 40 41in your git repository. git-p4 stores the depot path of the original import in 42the .git/config file and remembers the last imported p4 revision as a git tag 43called p4/<changenum> . 44 45Submitting 46========== 47 48git-p4 has EXPERIMENTAL support for submitting changes from a git repository 49back to a Perforce depot. This requires a Perforce checkout separate to your 50git repository. This is the basic procedure: 51 52 cd path/to/your/perforce/checkout 53 git-p4.py submit --git-dir=/path/to/your/git/repository 54 55This will create a temporary git branch, use git-rev-list to find out which git 56commits are in your current branch but not in the "origin" branch. You can 57override the name of the "origin" branch by using the --origin=mybranch option. 58The "origin" branch has to be the branch populated with git-p4's sync 59operation. 60 61After some preparations (which might take a while) git-p4 enters a loop where 62it will first show a Perforce submit template and a diff of the change to 63apply. After quitting the pager with 'q' git-p4 asks for confirmation for 64issuing the "p4 submit" command and also gives you the option of editing the 65submit template using "e". 66 67If a submit fails you may have to "p4 resolve" and submit manually. You can 68continue importing the remaining changes with 69 70 git-p4.py submit --git-dir=/path/to/your/git/repository --continue 71 72After submitting you should sync your origin branch from Perforce using 73git-p4's sync command. 74
