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 from 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 - -Example -======= - -# Clone a repository - git-p4 clone //depot/path/project -# Enter the newly cloned directory - cd project -# Do some work... - vi foo.h -# ... and commit locally to gi - git commit foo.h -# In the meantime somebody submitted changes to the Perforce depot.
