git p4 clone [<sync options>] [<clone options>] <p4 depot path>... git p4 sync [<sync options>] [<p4 depot path>...] git p4 rebase git p4 submit [<submit options>] [<master branch name>]
•Clone a repository:
$ git p4 clone //depot/path/project
•Do some work in the newly created Git repository:
$ cd project $ vi foo.h $ git commit -a -m "edited foo.h"
•Update the Git repository with recent changes from p4, rebasing your work on top:
$ git p4 rebase
•Submit your commits back to p4:
$ git p4 submit
$ git p4 clone //depot/path/project
1.Creates an empty Git repository in a subdirectory called project.
2.Imports the full contents of the head revision from the given p4 depot path into a single commit in the Git branch refs/remotes/p4/master.
3.Creates a local branch, master from this remote and checks it out.
$ git p4 clone //depot/path/project@all
$ git p4 sync
$ mkdir repo-git $ cd repo-git $ git init $ git p4 sync //path/in/your/perforce/depot
$ git p4 rebase
$ git p4 submit
$ git p4 submit topicbranch
$ git p4 submit --shelve $ git p4 submit --update-shelve 1234 --update-shelve 2345
Set the GIT_DIR environment variable. See git(1).-v, --verbose
Provide more progress information.
Import changes into <ref> instead of refs/remotes/p4/master. If <ref> starts with refs/, it is used as is. Otherwise, if it does not start with p4/, that prefix is added.By default a <ref> not starting with refs/ is treated as the name of a remote-tracking branch (under refs/remotes/). This behavior can be modified using the --import-local option.The default <ref> is "master".This example imports a new remote "p4/proj2" into an existing Git repository:--detect-branches
$ git init $ git p4 sync --branch=refs/remotes/p4/proj2 //depot/proj2
Use the branch detection algorithm to find new paths in p4. It is documented below in "BRANCH DETECTION".--changesfile <file>
Import exactly the p4 change numbers listed in file, one per line. Normally, git p4 inspects the current p4 repository state and detects the changes it should import.--silent
Do not print any progress information.--detect-labels
Query p4 for labels associated with the depot paths, and add them as tags in Git. Limited usefulness as only imports labels associated with new changelists. Deprecated.--import-labels
Import labels from p4 into Git.--import-local
By default, p4 branches are stored in refs/remotes/p4/, where they will be treated as remote-tracking branches by git-branch(1) and other commands. This option instead puts p4 branches in refs/heads/p4/. Note that future sync operations must specify --import-local as well so that they can find the p4 branches in refs/heads.--max-changes <n>
Import at most n changes, rather than the entire range of changes included in the given revision specifier. A typical usage would be use @all as the revision specifier, but then to use --max-changes 1000 to import only the last 1000 revisions rather than the entire revision history.--changes-block-size <n>
The internal block size to use when converting a revision specifier such as @all into a list of specific change numbers. Instead of using a single call to p4 changes to find the full list of changes for the conversion, there are a sequence of calls to p4 changes -m, each of which requests one block of changes of the given size. The default block size is 500, which should usually be suitable.--keep-path
The mapping of file names from the p4 depot path to Git, by default, involves removing the entire depot path. With this option, the full p4 depot path is retained in Git. For example, path //depot/main/foo/bar.c, when imported from //depot/main/, becomes foo/bar.c. With --keep-path, the Git path is instead depot/main/foo/bar.c.--use-client-spec
Use a client spec to find the list of interesting files in p4. See the "CLIENT SPEC" section below.-/ <path>
Exclude selected depot paths when cloning or syncing.
Where to create the Git repository. If not provided, the last component in the p4 depot path is used to create a new directory.--bare
Perform a bare clone. See git-clone(1).
Upstream location from which commits are identified to submit to p4. By default, this is the most recent p4 commit reachable from HEAD.-M
Detect renames. See git-diff(1). Renames will be represented in p4 using explicit move operations. There is no corresponding option to detect copies, but there are variables for both moves and copies.--preserve-user
Re-author p4 changes before submitting to p4. This option requires p4 admin privileges.--export-labels
Export tags from Git as p4 labels. Tags found in Git are applied to the perforce working directory.-n, --dry-run
Show just what commits would be submitted to p4; do not change state in Git or p4.--prepare-p4-only
Apply a commit to the p4 workspace, opening, adding and deleting files in p4 as for a normal submit operation. Do not issue the final "p4 submit", but instead print a message about how to submit manually or revert. This option always stops after the first (oldest) commit. Git tags are not exported to p4.--shelve
Instead of submitting create a series of shelved changelists. After creating each shelve, the relevant files are reverted/deleted. If you have multiple commits pending multiple shelves will be created.--update-shelve CHANGELIST
Update an existing shelved changelist with this commit. Implies --shelve. Repeat for multiple shelved changelists.--conflict=(ask|skip|quit)
Conflicts can occur when applying a commit to p4. When this happens, the default behavior ("ask") is to prompt whether to skip this commit and continue, or quit. This option can be used to bypass the prompt, causing conflicting commits to be automatically skipped, or to quit trying to apply commits, without prompting.--branch <branch>
After submitting, sync this named branch instead of the default p4/master. See the "Sync options" section above for more information.
Import p4 labels.
Import one commit with all files in the #head change under that tree."//depot/my/project@all"
Import one commit for each change in the history of that depot path."//depot/my/project@1,6"
Import only changes 1 through 6."//depot/proj1@all //depot/proj2@all"
Import all changes from both named depot paths into a single repository. Only files below these directories are included. There is not a subdirectory in Git for each "proj1" and "proj2". You must use the --destination option when specifying more than one depot path. The revision specifier must be specified identically on each depot path. If there are files in the depot paths with the same name, the path with the most recently updated version of the file is the one that appears in Git.
git p4 clone --detect-branches //depot@all
git init depot cd depot git config git-p4.branchList main:branch1 git p4 clone --detect-branches //depot@all .
User specified as an option to all p4 commands, with -u <user>. The environment variable P4USER can be used instead.git-p4.password
Password specified as an option to all p4 commands, with -P <password>. The environment variable P4PASS can be used instead.git-p4.port
Port specified as an option to all p4 commands, with -p <port>. The environment variable P4PORT can be used instead.git-p4.host
Host specified as an option to all p4 commands, with -h <host>. The environment variable P4HOST can be used instead.git-p4.client
Client specified as an option to all p4 commands, with -c <client>, including the client spec.git-p4.retries
Specifies the number of times to retry a p4 command (notably, p4 sync) if the network times out. The default value is 3. Set the value to 0 to disable retries or if your p4 version does not support retries (pre 2012.2).
Because importing commits from other Git repositories is much faster than importing them from p4, a mechanism exists to find p4 changes first in Git remotes. If branches exist under refs/remote/origin/p4, those will be fetched and used when syncing from p4. This variable can be set to false to disable this behavior.git-p4.branchUser
One phase in branch detection involves looking at p4 branches to find new ones to import. By default, all branches are inspected. This option limits the search to just those owned by the single user named in the variable.git-p4.branchList
List of branches to be imported when branch detection is enabled. Each entry should be a pair of branch names separated by a colon (:). This example declares that both branchA and branchB were created from main:git-p4.ignoredP4Labels
git config git-p4.branchList main:branchA git config --add git-p4.branchList main:branchB
List of p4 labels to ignore. This is built automatically as unimportable labels are discovered.git-p4.importLabels
Import p4 labels into git, as per --import-labels.git-p4.labelImportRegexp
Only p4 labels matching this regular expression will be imported. The default value is [a-zA-Z0-9_\-.]+$.git-p4.useClientSpec
Specify that the p4 client spec should be used to identify p4 depot paths of interest. This is equivalent to specifying the option --use-client-spec. See the "CLIENT SPEC" section above. This variable is a boolean, not the name of a p4 client.git-p4.pathEncoding
Perforce keeps the encoding of a path as given by the originating OS. Git expects paths encoded as UTF-8. Use this config to tell git-p4 what encoding Perforce had used for the paths. This encoding is used to transcode the paths to UTF-8. As an example, Perforce on Windows often uses "cp1252" to encode path names.git-p4.largeFileSystem
Specify the system that is used for large (binary) files. Please note that large file systems do not support the git p4 submit command. Only Git LFS is implemented right now (see https://git-lfs.github.com/ for more information). Download and install the Git LFS command line extension to use this option and configure it like this:git-p4.largeFileExtensions
git config git-p4.largeFileSystem GitLFS
All files matching a file extension in the list will be processed by the large file system. Do not prefix the extensions with ..git-p4.largeFileThreshold
All files with an uncompressed size exceeding the threshold will be processed by the large file system. By default the threshold is defined in bytes. Add the suffix k, m, or g to change the unit.git-p4.largeFileCompressedThreshold
All files with a compressed size exceeding the threshold will be processed by the large file system. This option might slow down your clone/sync process. By default the threshold is defined in bytes. Add the suffix k, m, or g to change the unit.git-p4.largeFilePush
Boolean variable which defines if large files are automatically pushed to a server.git-p4.keepEmptyCommits
A changelist that contains only excluded files will be imported as an empty commit if this boolean option is set to true.git-p4.mapUser
Map a P4 user to a name and email address in Git. Use a string with the following format to create a mapping:A mapping will override any user information from P4. Mappings for multiple P4 user can be defined.
git config --add git-p4.mapUser "p4user = First Last <firstname.lastname@example.org>"
Detect renames. See git-diff(1). This can be true, false, or a score as expected by git diff -M.git-p4.detectCopies
Detect copies. See git-diff(1). This can be true, false, or a score as expected by git diff -C.git-p4.detectCopiesHarder
Detect copies harder. See git-diff(1). A boolean.git-p4.preserveUser
On submit, re-author changes to reflect the Git author, regardless of who invokes git p4 submit.git-p4.allowMissingP4Users
When preserveUser is true, git p4 normally dies if it cannot find an author in the p4 user map. This setting submits the change regardless.git-p4.skipSubmitEdit
The submit process invokes the editor before each p4 change is submitted. If this setting is true, though, the editing step is skipped.git-p4.skipSubmitEditCheck
After editing the p4 change message, git p4 makes sure that the description really was changed by looking at the file modification time. This option disables that test.git-p4.allowSubmit
By default, any branch can be used as the source for a git p4 submit operation. This configuration variable, if set, permits only the named branches to be used as submit sources. Branch names must be the short names (no "refs/heads/"), and should be separated by commas (","), with no spaces.git-p4.skipUserNameCheck
If the user running git p4 submit does not exist in the p4 user map, git p4 exits. This option can be used to force submission regardless.git-p4.attemptRCSCleanup
If enabled, git p4 submit will attempt to cleanup RCS keywords ($Header$, etc). These would otherwise cause merge conflicts and prevent the submit going ahead. This option should be considered experimental at present.git-p4.exportLabels
Export Git tags to p4 labels, as per --export-labels.git-p4.labelExportRegexp
Only p4 labels matching this regular expression will be exported. The default value is [a-zA-Z0-9_\-.]+$.git-p4.conflict
Specify submit behavior when a conflict with p4 is found, as per --conflict. The default behavior is ask.
•Changesets from p4 are imported using Git fast-import.
•Cloning or syncing does not require a p4 client; file contents are collected using p4 print.
•Submitting requires a p4 client, which is not in the same location as the Git repository. Patches are applied, one at a time, to this p4 client and submitted from there.
•Each commit imported by git p4 has a line at the end of the log message indicating the p4 depot location and change number. This line is used by later git p4 sync operations to know which p4 changes are new.
