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. + + +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 +------------ + +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'. + + +OPTIONS +------- + +General options +~~~~~~~~~~~~~~~ +All commands except clone accept this option. + +--git-dir :: + Set the 'GIT_DIR' environment variable. See linkgit:git[1]. + +Sync options +~~~~~~~~~~~~ +These options can be used in the initial 'clone' as well as in +subsequent 'sync' operations. + +--branch :: + Import changes into given branch. If the branch starts with + 'refs/', it will be used as is, otherwise the path 'refs/heads/' + will be prepended. The default branch is 'master'. If used + with an initial clone, no HEAD will be checked out. ++ +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 :: + 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. + +--verbose:: + Provide more progress information. + +--detect-labels:: + Query p4 for labels associated with the depot paths, and add + them as tags in 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 :: + Limit the number of imported changes to 'n'. Useful to + limit the amount of history when using the '@all' p4 revision + specifier. + +--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. + +Clone options +~~~~~~~~~~~~~ +These options can be used in an initial 'clone', along with the 'sync' +options described above. + +--destination :: + 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]. + +-/ :: + Exclude selected depot paths when cloning. + +Submit options +~~~~~~~~~~~~~~ +These options can be used to modify 'git p4 submit' behavior. + +--verbose:: + Provide more progress information. + +--origin :: + 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. + + +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. Git-p4 can consult the client +spec when given the '--use-client-spec' option or useClientSpec +variable. + +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 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 '. + The environment variable 'P4USER' can be used instead. + +git-p4.password:: + Password specified as an option to all p4 commands, with + '-P '. + The environment variable 'P4PASS' can be used instead. + +git-p4.port:: + Port specified as an option to all p4 commands, with + '-p '. + The environment variable 'P4PORT' can be used instead. + +git-p4.host:: + Host specified as an option to all p4 commands, with + '-h '. + The environment variable 'P4HOST' can be used instead. + +git-p4.client:: + Client specified as an option to all p4 commands, with + '-c ', including the client spec. + +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.useClientSpec:: + Specify that the p4 client spec should be used to identify p4 + depot paths of interest.

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. + + +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 manual describes +the mechanisms git uses to request these credentials, as well as some +features to avoid inputting these credentials repeatedly. + +REQUESTING CREDENTIALS +---------------------- + +Without any credential helpers defined, git will try the following +strategies to ask the user for usernames and passwords: + +1. If the `GIT_ASKPASS` environment variable is set, the program + specified by the variable is invoked. A suitable prompt is provided + to the program on the command line, and the user's input is read + from its standard output. + +2. Otherwise, if the `core.askpass` configuration variable is set, its + value is used as above. + +3. Otherwise, if the `SSH_ASKPASS` environment variable is set, its + value is used as above. + +4. Otherwise, the user is prompted on the terminal. + +AVOIDING REPETITION +------------------- + +It can be cumbersome to input the same credentials over and over. Git +provides two methods to reduce this annoyance: + +1. Static configuration of usernames for a given authentication context. + +2. Credential helpers to cache or store passwords, or to interact with + a system password wallet or keychain. + +The first is simple and appropriate if you do not have secure storage available +for a password. It is generally configured by adding this to your config: + +--------------------------------------- +[credential "https://example.com"] + username = me +--------------------------------------- + +Credential helpers, on the other hand, are external programs from which git can +request both usernames and passwords; they typically interface with secure +storage provided by the OS or other programs. + +To use a helper, you must first select one to use. Git currently +includes the following helpers: + +cache:: + + Cache credentials in memory for a short period of time. See + linkgit:git-credential-cache[1] for details. + +store:: + + Store credentials indefinitely on disk. See + linkgit:git-credential-store[1] for details. + +You may also have third-party helpers installed; search for +`credential-*` in the output of `git help -a`, and consult the +documentation of individual helpers. Once you have selected a helper, +you can tell git to use it by putting its name into the +credential.helper variable. + +1.

Once git has acquired both a username and a +password, no more helpers will be tried. + + +CREDENTIAL CONTEXTS +------------------- + +Git considers each credential to have a context defined by a URL. This context +is used to look up context-specific configuration, and is passed to any +helpers, which may use it as an index into secure storage. + +For instance, imagine we are accessing `https://example.com/foo.git`. When git +looks into a config file to see if a section matches this context, it will +consider the two a match if the context is a more-specific subset of the +pattern in the config file. For example, if you have this in your config file: + +-------------------------------------- +[credential "https://example.com"] + username = foo +-------------------------------------- + +then we will match: both protocols are the same, both hosts are the same, and +the "pattern" URL does not care about the path component at all. However, this +context would not match: + +-------------------------------------- +[credential "https://kernel.org"] + username = foo +-------------------------------------- + +because the hostnames differ. Nor would it match `foo.example.com`; git +compares hostnames exactly, without considering whether two hosts are part of +the same domain. Likewise, a config entry for `http://example.com` would not +match: git compares the protocols exactly. + + +CONFIGURATION OPTIONS +--------------------- + +Options for a credential context can be configured either in +`credential.\*` (which applies to all credentials), or +`credential..\*`, where matches the context as described +above. + +The following options are available in either location: + +helper:: + + The name of an external credential helper, and any associated options. + If the helper name is not an absolute path, then the string `git + credential-` is prepended. The resulting string is executed by the + shell (so, for example, setting this to `foo --option=bar` will execute + `git credential-foo --option=bar` via the shell. See the manual of + specific helpers for examples of their use. + +username:: + + A default username, if one is not provided in the URL. + +useHttpPath:: + + By default, git does not consider the "path" component of an http URL + to be worth matching via external helpers. This means that a credential + stored for `https://example.com/foo.git` will also be used for + `https://example.com/bar.git`. If you do want to distinguish these + cases, set this option to `true`. + + +CUSTOM HELPERS +-------------- + +You can write your own custom helpers to interface with any system in +which you keep credentials.

This assures the + integrator that the pulled history is authentic and allows others to + later validate it. +Content-type: text/asciidoc + +Using signed tag in pull requests +================================= + +A typical distributed workflow using Git is for a contributor to fork a +project, build on it, publish the result to her public repository, and ask +the "upstream" person (often the owner of the project where she forked +from) to pull from her public repository. Requesting such a "pull" is made +easy by the `git request-pull` command. + +Earlier, a typical pull request may have started like this: + +------------ + The following changes since commit 406da78032179...: + + Froboz 3.2 (2011-09-30 14:20:57 -0700) + + are available in the git repository at: + + example.com:/git/froboz.git for-xyzzy +------------ + +followed by a shortlog of the changes and a diffstat. + +The request was for a branch name (e.g. `for-xyzzy`) in the public +repository of the contributor, and even though it stated where the +contributor forked her work from, the message did not say anything about +the commit to expect at the tip of the for-xyzzy branch. If the site that +hosts the public repository of the contributor cannot be fully trusted, it +was unnecessarily hard to make sure what was pulled by the integrator was +genuinely what the contributor had produced for the project. Also there +was no easy way for third-party auditors to later verify the resulting +history. + +Starting from Git release v1.7.9, a contributor can add a signed tag to +the commit at the tip of the history and ask the integrator to pull that +signed tag. When the integrator runs `git pull`, the signed tag is +automatically verified to assure that the history is not tampered with. +In addition, the resulting merge commit records the content of the signed +tag, so that other people can verify that the branch merged by the +integrator was signed by the contributor, without fetching the signed tag +used to validate the pull request separately and keeping it in the refs +namespace. + +This document describes the workflow between the contributor and the +integrator, using Git v1.7.9 or later. + + +A contributor or a lieutenant +----------------------------- + +After preparing her work to be pulled, the contributor uses `git tag -s` +to create a signed tag: + +------------ + $ git checkout work + $ ... "git pull" from sublieutenants, "git commit" your own work ... + $ git tag -s -m "Completed frotz feature" frotz-for-xyzzy work +------------ + +Note that this example uses the `-m` option to create a signed tag with +just a one-liner message, but this is for illustration purposes only. It +is advisable to compose a well-written explanation of what the topic does +to justify why it is worthwhile for the integrator to pull it, as this +message will eventually become part of the final history after the +integrator responds to the pull request (as we will see later). + +Then she pushes the tag out to her public repository: + +------------ + $ git push example.com:/git/froboz.git/ +frotz-for-xyzzy +------------ + +There is no need to push the `work` branch or anything else. + +Note that the above command line used a plus sign at the beginning of +`+frotz-for-xyzzy` to allow forcing the update of a tag, as the same +contributor may want to reuse a signed tag with the same name after the +previous pull request has already been responded to. + +The contributor then prepares a message to request a "pull": + +------------ + $ git request-pull v3.2 example.com:/git/froboz.git/ frotz-for-xyzzy >msg.txt +------------ + +The arguments are: + +. the version of the integrator's commit the contributor based her work on; +. the URL of the repository, to which the contributor has pushed what she + wants to get pulled; and +. the name of the tag the contributor wants to get pulled (earlier, she could + write only a branch name here). + +The resulting msg.txt file begins like so: + +------------ + The following changes since commit 406da78032179...: + + Froboz 3.2 (2011-09-30 14:20:57 -0700) + + are available in the git repository at: + + example.com:/git/froboz.git tags/frotz-for-xyzzy + + for you to fetch changes up to 703f05ad5835c...: + + Add tests and documentation for frotz (2011-12-02 10:02:52 -0800) + + ----------------------------------------------- + Completed frotz feature + ----------------------------------------------- +------------ + +followed by a shortlog of the changes and a diffstat. Comparing this with +the earlier illustration of the output from the traditional `git request-pull` +command, the reader should notice that: + +. The tip commit to expect is shown to the integrator; and +. The signed tag message is shown prominently between the dashed lines + before the shortlog. + +The latter is why the contributor would want to justify why pulling her +work is worthwhile when creating the signed tag. The contributor then +opens her favorite MUA, reads msg.txt, edits and sends it to her upstream +integrator. + + +Integrator +---------- + +After receiving such a pull request message, the integrator fetches and +integrates the tag named in the request, with: + +------------ + $ git pull example.com:/git/froboz.git/ tags/frotz-for-xyzzy +------------ + +This operation will always open an editor to allow the integrator to fine +tune the commit log message when merging a signed tag. Also, pulling a +signed tag will always create a merge commit even when the integrator does +not have any new commit since the contributor's work forked (i.e. 'fast +forward'), so that the integrator can properly explain what the merge is +about and why it was made. + +In the editor, the integrator will see something like this: + +------------ + Merge tag 'frotz-for-xyzzy' of example.com:/git/froboz.git/ + + Completed frotz feature + # gpg: Signature made Fri 02 Dec 2011 10:03:01 AM PST using RSA key ID 96AFE6CB + # gpg: Good signature from "Con Tributor " +------------ + +Notice that the message recorded in the signed tag "Completed frotz +feature" appears here, and again that is why it is important for the +contributor to explain her work well when creating the signed tag. + +As usual, the lines commented with `#` are stripped out. The resulting +commit records the signed tag used for this validation in a hidden field +so that it can later be used by others to audit the history. There is no +need for the integrator to keep a separate copy of the tag in his +repository (i.e. `git tag -l` won't list the `frotz-for-xyzzy` tag in the +above example), and there is no need to publish the tag to his public +repository, either. + +After the integrator responds to the pull request and her work becomes +part of the permanent history, the contributor can remove the tag from +her public repository, if she chooses, in order to keep the tag namespace +of her public repository clean, with: + +------------ + $ git push example.com:/git/froboz.git :frotz-for-xyzzy +------------ + + +Auditors +-------- + +The `--show-signature` option can be given to `git log` or `git show` and +shows the verification status of the embedded signed tag in merge commits +created when the integrator responded to a pull request of a signed tag. + +A typical output from `git show --show-signature` may look like this: + +------------ + $ git show --show-signature + commit 02306ef6a3498a39118aef9df7975bdb50091585 + merged tag 'frotz-for-xyzzy' + gpg: Signature made Fri 06 Jan 2012 12:41:49 PM PST using RSA key ID 96AFE6CB + gpg: Good signature from "Con Tributor " + Merge: 406da78 703f05a + Author: Inte Grator + Date: Tue Jan 17 13:49:41 2012 -0800 + + Merge tag 'frotz-for-xyzzy' of example.com:/git/froboz.git/ + + Completed frotz feature + + * tag 'frotz-for-xyzzy' (100 commits) + Add tests and documentation for frotz + ... +------------ + +There is no need for the auditor to explicitly fetch the contributor's +signature, or to even be aware of what tag(s) the contributor and integrator +used to communicate the signature.

The string is transformed +by git into a command to be executed using these rules: + + 1. If the helper string begins with "!", it is considered a shell + snippet, and everything after the "!" becomes the command. + + 2. Otherwise, if the helper string begins with an absolute path, the + verbatim helper string becomes the command. + + 3. Otherwise, the string "git credential-" is prepended to the helper + string, and the result becomes the command. + +The resulting command then has an "operation" argument appended to it +(see below for details), and the result is executed by the shell. + +Here are some example specifications: + +---------------------------------------------------- +# run "git credential-foo" +foo + +# same as above, but pass an argument to the helper +foo --bar=baz + +# the arguments are parsed by the shell, so use shell +# quoting if necessary +foo --bar="whitespace arg" + +# you can also use an absolute path, which will not use the git wrapper +/path/to/my/helper --with-arguments + +# or you can specify your own shell snippet +!f() { echo "password=`cat $HOME/.secret`"; }; f +---------------------------------------------------- + +Generally speaking, rule (3) above is the simplest for users to specify. +Authors of credential helpers should make an effort to assist their +users by naming their program "git-credential-$NAME", and putting it in +the $PATH or $GIT_EXEC_PATH during installation, which will allow a user +to enable it with `git config credential.helper $NAME`. + +When a helper is executed, it will have one "operation" argument +appended to its command line, which is one of: + +`get`:: + + Return a matching credential, if any exists. + +`store`:: + + Store the credential, if applicable to the helper. + +`erase`:: + + Remove a matching credential, if any, from the helper's storage. + +The details of the credential will be provided on the helper's stdin +stream. The credential is split into a set of named attributes. +Attributes are provided to the helper, one per line. Each attribute is +specified by a key-value pair, separated by an `=` (equals) sign, +followed by a newline. The key may contain any bytes except `=`, +newline, or NUL. The value may contain any bytes except newline or NUL. +In both cases, all bytes are treated as-is (i.e., there is no quoting, +and one cannot transmit a value with newline or NUL in it). The list of +attributes is terminated by a blank line or end-of-file. + +Git will send the following attributes (but may not send all of +them for a given credential; for example, a `host` attribute makes no +sense when dealing with a non-network protocol): + +`protocol`:: + + The protocol over which the credential will be used (e.g., + `https`). + +`host`:: + + The remote hostname for a network credential. + +`path`:: + + The path with which the credential will be used. E.g., for + accessing a remote https repository, this will be the + repository's path on the server. + +`username`:: + + The credential's username, if we already have one (e.g., from a + URL, from the user, or from a previously run helper). + +`password`:: + + The credential's password, if we are asking it to be stored. + +For a `get` operation, the helper should produce a list of attributes +on stdout in the same format. A helper is free to produce a subset, or +even no values at all if it has nothing useful to provide. Any provided +attributes will overwrite those already known about by git. + +For a `store` or `erase` operation, the helper's output is ignored. +If it fails to perform the requested operation, it may complain to +stderr to inform the user. If it does not support the requested +operation (e.g., a read-only store), it should silently ignore the +request. + +If a helper receives any other operation, it should silently ignore the +request.
