When -a <//p4repo/path> and <branch> are specified a new branch with the -given name will be created and the initial import will begin. - -Once the initial import is complete you can do an incremental import -of new commits from the Perforce repository. You do this by checking -out the appropriate git branch and then running `git-p4import` without -any options. - -The standard p4 client is used to communicate with the Perforce -repository; it must be configured correctly in order for `git-p4import` -to operate (see below). - - -OPTIONS -------- --q:: - Do not display any progress information. - --v:: - Give extra progress information. - -\--authors:: - Specify an authors file containing a mapping of Perforce user - ids to full names and email addresses (see Notes below). - -\--notags:: - Do not create a tag for each imported commit. - -\--stitch:: - Import the contents of the given perforce branch into the - currently checked out git branch. - -\--log:: - Store debugging information in the specified file. - --t:: - Specify that the remote repository is in the specified timezone. - Timezone must be in the format "US/Pacific" or "Europe/London" - etc. You only need to specify this once, it will be saved in - the git config file for the repository. - -<//p4repo/path>:: - The Perforce path that will be imported into the specified branch. - -<branch>:: - The new branch that will be created to hold the Perforce imports. - - -P4 Client ---------- -You must make the `p4` client command available in your $PATH and -configure it to communicate with the target Perforce repository. -Typically this means you must set the "$P4PORT" and "$P4CLIENT" -environment variables. - -You must also configure a `p4` client "view" which maps the Perforce -branch into the top level of your git repository, for example: - ------------- -Client: myhost - -Root: /home/sean/import - -Options: noallwrite clobber nocompress unlocked modtime rmdir - -View: - //public/jam/... //myhost/jam/... ------------- - -With the above `p4` client setup, you could import the "jam" -perforce branch into a branch named "jammy", like so: - ------------- -$ mkdir -p /home/sean/import/jam -$ cd /home/sean/import/jam -$ git init -$ git p4import //public/jam jammy ------------- - - -Multiple Branches ------------------ -Note that by creating multiple "views" you can use `git-p4import` -to import additional branches into the same git repository. -However, the `p4` client has a limitation in that it silently -ignores all but the last "view" that maps into the same local -directory. So the following will *not* work: - ------------- -View: - //public/jam/... //myhost/jam/... - //public/other/... //myhost/jam/... - //public/guest/... //myhost/jam/... ------------- - -If you want more than one Perforce branch to be imported into the -same directory you must employ a workaround. A simple option is -to adjust your `p4` client before each import to only include a -single view. - -Another option is to create multiple symlinks locally which all -point to the same directory in your git repository and then use -one per "view" instead of listing the actual directory. - - -Tags ----- -A git tag of the form p4/xx is created for every change imported from -the Perforce repository where xx is the Perforce changeset number. -Therefore after the import you can use git to access any commit by its -Perforce number, e.g. git show p4/327. - -The tag associated with the HEAD commit is also how `git-p4import` -determines if there are new changes to incrementally import from the -Perforce repository. - -If you import from a repository with many thousands of changes -you will have an equal number of p4/xxxx git tags. Git tags can -be expensive in terms of disk space and repository operations. -If you don't need to perform further incremental imports, you -may delete the tags. - - -Notes ------ -You can interrupt the import (e.g. ctrl-c) at any time and restart it -without worry. - -Author information is automatically determined by querying the -Perforce "users" table using the id associated with each change. -However, if you want to manually supply these mappings you can do -so with the "--authors" option. It accepts a file containing a list -of mappings with each line containing one mapping in the format: - ------------- - perforce_id = Full Name <email@address.com> ------------- - - -Author ------- -Written by Sean Estabrooks <seanlkml@sympatico.ca> - - -GIT ---- -Part of the gitlink:git[7] suite |
