Lint for and fix the three manual pages that were missing the standard "Part of the linkgit:git[1] suite" end section. We only do this for the man[157] section documents (we don't have anything outside those sections), not files to be included, howto *.txt files etc. We could also add this to the existing (and then renamed) lint-gitlink.perl, but I'm not doing that here. Obviously all of that fits in one script, but I think for something like this that's a one-off script with global variables it's much harder to follow when a large part of your script is some if/else or keeping/resetting of state simply to work around the script doing two things instead of one. Especially because in this case this script wants to process the file as one big string, but lint-gitlink.perl wants to look at it one line at a time. We could also consolidate this whole thing and t/check-non-portable-shell.pl, but that one likes to join lines as part of its shell parsing. So let's just add another script, whole scaffolding is basically: use strict; use warnings; sub report { ... } my $code = 0; while (<>) { ... } exit $code; We'd spend more lines effort trying to consolidate them than just copying that around.

--------
|
|
[verse]
|
|
'git p4 clone' [<sync options>] [<clone options>] <p4 depot path>...
|
|
'git p4 sync' [<sync options>] [<p4 depot path>...]

DESCRIPTION
|
|
-----------
|
|
This command provides a way to interact with p4 repositories
|
|
using Git.
|
|
|
|
Create a new Git repository from an existing p4 repository using
|
|
'git p4 clone', giving it one or more p4 depot paths. Incorporate
|
|
new commits from p4 changes with 'git p4 sync'. The 'sync' command
|
|
is also used to include new branches from other p4 depot paths.
|
|
Submit Git changes back to p4 using 'git p4 submit'. The command
|
|
'git p4 rebase' does a sync plus rebases the current branch onto
|
|
the updated p4 remote branch.
|
|
|
|
|
|
EXAMPLES
|
|
--------
|
|
* 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
|
|
------------
|
|
|
|
|
|
COMMANDS
|
|
--------
|
|
|
|
Clone
|
|
~~~~~
|
|
Generally, 'git p4 clone' is used to create a new Git directory
|
|
from an existing p4 repository:
|
|
------------
|
|
$ git p4 clone //depot/path/project
|
|
------------
|
|
This:
|
|
|
|
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.
|
|
|
|
To reproduce the entire p4 history in Git, use the '@all' modifier on
|
|
the depot path:
|
|
------------
|
|
$ git p4 clone //depot/path/project@all
|
|
------------
|
|
|
|
|
|
Sync
|
|
~~~~
|
|
As development continues in the p4 repository, those changes can
|
|
be included in the Git repository using:
|
|
------------
|
|
$ git p4 sync
|
|
------------
|
|
This command finds new changes in p4 and imports them as Git commits.
|
|
|
|
P4 repositories can be added to an existing Git repository using
|
|
'git p4 sync' too:
|
|
------------
|
|
$ mkdir repo-git
|
|
$ cd repo-git
|
|
$ git init
|
|
$ git p4 sync //path/in/your/perforce/depot
|
|
------------
|
|
This imports the specified depot into
|
|
'refs/remotes/p4/master' in an existing Git repository. The
|
|
`--branch` option can be used to specify a different branch to
|
|
be used for the p4 content.
|
|
|
|
If a Git repository includes branches 'refs/remotes/origin/p4', these
|
|
will be fetched and consulted first during a 'git p4 sync'. Since
|
|
importing directly from p4 is considerably slower than pulling changes
|
|
from a Git remote, this can be useful in a multi-developer environment.
|
|
|
|
If there are multiple branches, doing 'git p4 sync' will automatically
|
|
use the "BRANCH DETECTION" algorithm to try to partition new changes
|
|
into the right branch. This can be overridden with the `--branch`
|
|
option to specify just a single branch to update.
|
|
|
|
|
|
Rebase
|
|
~~~~~~
|
|
A common working pattern is to fetch the latest changes from the p4 depot
|
|
and merge them with local uncommitted changes. Often, the p4 repository
|
|
is the ultimate location for all code, thus a rebase workflow makes
|
|
sense. This command does 'git p4 sync' followed by 'git rebase' to move
|
|
local commits on top of updated p4 changes.
|
|
------------
|
|
$ git p4 rebase
|
|
------------
|
|
|
|
|
|
Submit
|
|
~~~~~~
|
|
Submitting changes from a Git repository back to the p4 repository
|
|
requires a separate p4 client workspace. This should be specified
|
|
using the `P4CLIENT` environment variable or the Git configuration
|
|
variable 'git-p4.client'. The p4 client must exist, but the client root
|
|
will be created and populated if it does not already exist.
|
|
|
|
To submit all changes that are in the current Git branch but not in
|
|
the 'p4/master' branch, use:
|
|
------------
|
|
$ git p4 submit
|
|
------------
|
|
|
|
To specify a branch other than the current one, use:
|
|
------------
|
|
$ git p4 submit topicbranch
|
|
------------
|
|
|
|
To specify a single commit or a range of commits, use:
|
|
------------
|
|
$ git p4 submit --commit <sha1>
|
|
$ git p4 submit --commit <sha1..sha1>
|
|
------------
|
|
|
|
The upstream reference is generally 'refs/remotes/p4/master', but can
|
|
be overridden using the `--origin=` command-line option.
|
|
|
|
The p4 changes will be created as the user invoking 'git p4 submit'. The
|
|
`--preserve-user` option will cause ownership to be modified
|
|
according to the author of the Git commit. This option requires admin
|
|
privileges in p4, which can be granted using 'p4 protect'.
|
|
|
|
To shelve changes instead of submitting, use `--shelve` and `--update-shelve`:
|
|
|
|
----
|
|
$ git p4 submit --shelve
|
|
$ git p4 submit --update-shelve 1234 --update-shelve 2345
|
|
----
|
|
|
|
|
|
Unshelve
|
|
~~~~~~~~
|
|
Unshelving will take a shelved P4 changelist, and produce the equivalent git commit
|
|
in the branch refs/remotes/p4-unshelved/<changelist>.
|
|
|
|
The git commit is created relative to the current origin revision (HEAD by default).
|
|
A parent commit is created based on the origin, and then the unshelve commit is
|
|
created based on that.
|
|
|
|
The origin revision can be changed with the "--origin" option.
|
|
|
|
If the target branch in refs/remotes/p4-unshelved already exists, the old one will
|
|
be renamed.
|
|
|
|
----
|
|
$ git p4 sync
|
|
$ git p4 unshelve 12345
|
|
$ git show p4-unshelved/12345
|
|
<submit more changes via p4 to the same files>
|
|
$ git p4 unshelve 12345
|
|
<refuses to unshelve until git is in sync with p4 again>
|
|
|

OPTIONS
|
|
-------
|
|
|
|
General options
|
|
~~~~~~~~~~~~~~~
|
|
All commands except clone accept these options.
|
|
|
|
--git-dir <dir>::
|
|
Set the `GIT_DIR` environment variable. See linkgit:git[1].
|
|
|
|
-v::
|
|
--verbose::
|
|
Provide more progress information.
|
|
|
|
Sync options
|
|
~~~~~~~~~~~~
|
|
These options can be used in the initial 'clone' as well as in
|
|
subsequent 'sync' operations.
|
|
|
|
--branch <ref>::
|
|
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:
|
|
+
|
|
----
|
|
$ git init
|
|
$ git p4 sync --branch=refs/remotes/p4/proj2 //depot/proj2
|
|
----
|
|
|
|
--detect-branches::
|
|
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
|
|
linkgit: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.
|
|
|
|
Clone options
|
|
~~~~~~~~~~~~~
|
|
These options can be used in an initial 'clone', along with the 'sync'
|
|
options described above.
|
|
|
|
--destination <directory>::
|
|
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 linkgit:git-clone[1].
|
|
|
|
Submit options
|
|
~~~~~~~~~~~~~~
|
|
These options can be used to modify 'git p4 submit' behavior.
|
|
|
|
--origin <commit>::
|
|
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 linkgit: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.
|
|
|
|
--commit <sha1>|<sha1..sha1>::
|
|
Submit only the specified commit or range of commits, instead of the full
|
|
list of changes that are in the current Git branch.
|
|
|
|
--disable-rebase::
|
|
Disable the automatic rebase after all commits have been successfully
|
|
submitted. Can also be set with git-p4.disableRebase.
|
|
|
|
--disable-p4sync::
|
|
Disable the automatic sync of p4/master from Perforce after commits have
|
|
been submitted. Implies --disable-rebase. Can also be set with
|
|
git-p4.disableP4Sync. Sync with origin/master still goes ahead if possible.
|
|
|
|
Hooks for submit
|
|
----------------
|
|
|
|
p4-pre-submit
|
|
~~~~~~~~~~~~~
|
|
|
|
The `p4-pre-submit` hook is executed if it exists and is executable.
|
|
The hook takes no parameters and nothing from standard input. Exiting with
|
|
non-zero status from this script prevents `git-p4 submit` from launching.
|
|
It can be bypassed with the `--no-verify` command line option.
|
|
|
|
One usage scenario is to run unit tests in the hook.
|
|
|
|
p4-prepare-changelist
|
|
~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The `p4-prepare-changelist` hook is executed right after preparing
|
|
the default changelist message and before the editor is started.
|
|
It takes one parameter, the name of the file that contains the
|
|
changelist text. Exiting with a non-zero status from the script
|
|
will abort the process.
|
|
|
|
The purpose of the hook is to edit the message file in place,
|
|
and it is not suppressed by the `--no-verify` option. This hook
|
|
is called even if `--prepare-p4-only` is set.
|
|
|
|
p4-changelist
|
|
~~~~~~~~~~~~~
|
|
|
|
The `p4-changelist` hook is executed after the changelist
|
|
message has been edited by the user. It can be bypassed with the
|
|
`--no-verify` option. It takes a single parameter, the name
|
|
of the file that holds the proposed changelist text. Exiting
|
|
with a non-zero status causes the command to abort.
|
|
|
|
The hook is allowed to edit the changelist file and can be used
|
|
to normalize the text into some project standard format. It can
|
|
also be used to refuse the Submit after inspect the message file.
|
|
|
|
p4-post-changelist
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
The `p4-post-changelist` hook is invoked after the submit has
|
|
successfully occurred in P4. It takes no parameters and is meant
|
|
primarily for notification and cannot affect the outcome of the
|
|
git p4 submit action.
|
|
|
|
|
|
|
|
Rebase options
|
|
~~~~~~~~~~~~~~
|
|
These options can be used to modify 'git p4 rebase' behavior.
|
|
|
|
--import-labels::
|
|
Import p4 labels.
|
|
|
|
Unshelve options
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
--origin::
|
|
Sets the git refspec against which the shelved P4 changelist is compared.
|
|
Defaults to p4/master.
|
|
|
|
DEPOT PATH SYNTAX
|
|
-----------------
|
|
The p4 depot path argument to 'git p4 sync' and 'git p4 clone' can
|
|
be one or more space-separated p4 depot paths, with an optional
|
|
p4 revision specifier on the end:
|
|
|
|
"//depot/my/project"::
|
|
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.
|
|
|
|
See 'p4 help revisions' for the full syntax of p4 revision specifiers.
|
|
|
|
|
|
CLIENT SPEC
|
|
-----------
|
|
The p4 client specification is maintained with the 'p4 client' command
|
|
and contains among other fields, a View that specifies how the depot
|
|
is mapped into the client repository. The 'clone' and 'sync' commands
|
|
can consult the client spec when given the `--use-client-spec` option or
|
|
when the useClientSpec variable is true. After 'git p4 clone', the
|
|
useClientSpec variable is automatically set in the repository
|
|
configuration file. This allows future 'git p4 submit' commands to
|
|
work properly; the submit command looks only at the variable and does
|
|
not have a command-line option.
|
|
|
|
The full syntax for a p4 view is documented in 'p4 help views'. 'git p4'
|
|
knows only a subset of the view syntax. It understands multi-line
|
|
mappings, overlays with '+', exclusions with '-' and double-quotes
|
|
around whitespace. Of the possible wildcards, 'git p4' only handles
|
|
'...', and only when it is at the end of the path. 'git p4' will complain
|
|
if it encounters an unhandled wildcard.
|
|
|
|
Bugs in the implementation of overlap mappings exist. If multiple depot
|
|
paths map through overlays to the same location in the repository,
|
|
'git p4' can choose the wrong one. This is hard to solve without
|
|
dedicating a client spec just for 'git p4'.
|
|
|
|
The name of the client can be given to 'git p4' in multiple ways. The
|
|
variable 'git-p4.client' takes precedence if it exists. Otherwise,
|
|
normal p4 mechanisms of determining the client are used: environment
|
|
variable `P4CLIENT`, a file referenced by `P4CONFIG`, or the local host name.
|
|
|
|
|
|
BRANCH DETECTION
|
|
----------------
|
|
P4 does not have the same concept of a branch as Git. Instead,
|
|
p4 organizes its content as a directory tree, where by convention
|
|
different logical branches are in different locations in the tree.
|
|
The 'p4 branch' command is used to maintain mappings between
|
|
different areas in the tree, and indicate related content. 'git p4'
|
|
can use these mappings to determine branch relationships.
|
|
|

If you have a repository where all the branches of interest exist as
|
|
subdirectories of a single depot path, you can use `--detect-branches`
|
|
when cloning or syncing to have 'git p4' automatically find
|
|
subdirectories in p4, and to generate these as branches in Git.
|
|
|
|
For example, if the P4 repository structure is:
|
|
----
|
|
//depot/main/...
|
|
//depot/branch1/...
|
|
----
|
|
|
|
And "p4 branch -o branch1" shows a View line that looks like:
|
|
----
|
|
//depot/main/... //depot/branch1/...
|
|
----
|
|
|
|
Then this 'git p4 clone' command:
|
|
----
|
|
git p4 clone --detect-branches //depot@all
|
|
----
|
|
produces a separate branch in 'refs/remotes/p4/' for //depot/main,
|
|
called 'master', and one for //depot/branch1 called 'depot/branch1'.
|
|
|
|
However, it is not necessary to create branches in p4 to be able to use
|
|
them like branches. Because it is difficult to infer branch
|
|
relationships automatically, a Git configuration setting
|
|
'git-p4.branchList' can be used to explicitly identify branch
|
|
relationships. It is a list of "source:destination" pairs, like a
|
|
simple p4 branch specification, where the "source" and "destination" are
|
|
the path elements in the p4 repository. The example above relied on the
|
|
presence of the p4 branch. Without p4 branches, the same result will
|
|
occur with:
|
|
----
|
|
git init depot
|
|
cd depot
|
|
git config git-p4.branchList main:branch1
|
|
git p4 clone --detect-branches //depot@all .
|
|

|
|
|
|
|
PERFORMANCE
|
|
-----------
|
|
The fast-import mechanism used by 'git p4' creates one pack file for
|
|
each invocation of 'git p4 sync'. Normally, Git garbage compression
|
|
(linkgit:git-gc[1]) automatically compresses these to fewer pack files,
|
|
but explicit invocation of 'git repack -adf' may improve performance.
|
|
|
|
|
|
CONFIGURATION VARIABLES
|
|
-----------------------
|
|
The following config settings can be used to modify 'git p4' behavior.
|
|
They all are in the 'git-p4' section.
|
|
|
|
General variables
|
|
~~~~~~~~~~~~~~~~~
|
|
git-p4.user::
|
|
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).
|
|
|
|
Clone and sync variables
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
git-p4.syncFromOrigin::
|
|
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 config git-p4.branchList main:branchA
|
|
git config --add git-p4.branchList main:branchB
|
|
-------------
|
|
|
|
git-p4.ignoredP4Labels::
|
|
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 config git-p4.largeFileSystem GitLFS
|
|
-------------
|
|
|
|
git-p4.largeFileExtensions::
|
|
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:
|
|
+
|
|
-------------
|
|
git config --add git-p4.mapUser "p4user = First Last <mail@address.com>"
|
|
-------------
|
|
+
|
|
A mapping will override any user information from P4. Mappings for
|
|
multiple P4 user can be defined.
|
|
|
|
Submit variables
|
|
~~~~~~~~~~~~~~~~
|
|
git-p4.detectRenames::
|
|
Detect renames. See linkgit:git-diff[1]. This can be true,
|
|
false, or a score as expected by 'git diff -M'.
|
|
|
|
git-p4.detectCopies::
|
|
Detect copies. See linkgit:git-diff[1]. This can be true,
|
|
false, or a score as expected by 'git diff -C'.
|
|
|
|
git-p4.detectCopiesHarder::
|
|
Detect copies harder. See linkgit: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'.
|
|
|
|
git-p4.disableRebase::
|
|
Do not rebase the tree against p4/master following a submit.
|
|
|
|
git-p4.disableP4Sync::
|
|
Do not sync p4/master with Perforce following a submit. Implies git-p4.disableRebase.
|
|
|
|
IMPLEMENTATION DETAILS
|
|
----------------------
|
|
* 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.
