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 <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. + +--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 <n>:: + 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 <directory>:: + Where to create the git repository.

By default, this is the most recent p4 commit reachable + from 'HEAD'. + +-M[<n>]:: + 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 <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. + +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 is equivalent to specifying the + option '--use-client-spec'.

See linkgit:git-diff[1]. + +git-p4.detectCopies:: + Detect copies. See linkgit:git-diff[1]. + +git-p4.detectCopiesHarder:: + Detect copies harder. See linkgit:git-diff[1]. + +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. + + +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. diff --git a/Documentation/git-pull.txt b/Documentation/git-pull.txt index e1da468766..0f18ec891a 100644 --- a/Documentation/git-pull.txt +++ b/Documentation/git-pull.txt @@ -108,7 +108,7 @@ include::merge-options.txt[] fetched, the rebase uses that information to avoid rebasing non-local changes. + -See `branch.<name>.rebase` and `branch.autosetuprebase` in +See `pull.rebase`, `branch.<name>.rebase` and `branch.autosetuprebase` in linkgit:git-config[1] if you want to make `git pull` always use `{litdd}rebase` instead of merging. + diff --git a/Documentation/git-push.txt b/Documentation/git-push.txt index 88acfcd4cc..aede48877f 100644 --- a/Documentation/git-push.txt +++ b/Documentation/git-push.txt @@ -162,6 +162,12 @@ useful if you write an alias or script around 'git push'. is specified.

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. Find a helper. ++ +------------------------------------------- +$ git help -a | grep credential- +credential-foo +------------------------------------------- + +2. Read its description. ++ +------------------------------------------- +$ git help credential-foo +------------------------------------------- + +3. Tell git to use it. ++ +------------------------------------------- +$ git config --global credential.helper foo +------------------------------------------- + +If there are multiple instances of the `credential.helper` configuration +variable, each helper will be tried in turn, and may provide a username, +password, or nothing. 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.<url>.\*`, where <url> 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.

Git can +expose each namespace as an independent repository to pull from and push +to, while sharing the object store, and exposing all the refs to +operations such as linkgit:git-gc[1]. + +Storing multiple repositories as namespaces of a single repository +avoids storing duplicate copies of the same objects, such as when +storing multiple branches of the same source. The alternates mechanism +provides similar support for avoiding duplicates, but alternates do not +prevent duplication between new objects added to the repositories +without ongoing maintenance, while namespaces do. + +To specify a namespace, set the `GIT_NAMESPACE` environment variable to +the namespace. For each ref namespace, git stores the corresponding +refs in a directory under `refs/namespaces/`. For example, +`GIT_NAMESPACE=foo` will store refs under `refs/namespaces/foo/`. You +can also specify namespaces via the `--namespace` option to +linkgit:git[1]. + +Note that namespaces which include a `/` will expand to a hierarchy of +namespaces; for example, `GIT_NAMESPACE=foo/bar` will store refs under +`refs/namespaces/foo/refs/namespaces/bar/`. This makes paths in +`GIT_NAMESPACE` behave hierarchically, so that cloning with +`GIT_NAMESPACE=foo/bar` produces the same result as cloning with +`GIT_NAMESPACE=foo` and cloning from that repo with `GIT_NAMESPACE=bar`. It +also avoids ambiguity with strange namespace paths such as `foo/refs/heads/`, +which could otherwise generate directory/file conflicts within the `refs` +directory. + +linkgit:git-upload-pack[1] and linkgit:git-receive-pack[1] rewrite the +names of refs as specified by `GIT_NAMESPACE`. git-upload-pack and +git-receive-pack will ignore all references outside the specified +namespace. + +The smart HTTP server, linkgit:git-http-backend[1], will pass +GIT_NAMESPACE through to the backend programs; see +linkgit:git-http-backend[1] for sample configuration to expose +repository namespaces as repositories. + +For a simple local test, you can use linkgit:git-remote-ext[1]: + +---------- +git clone ext::'git --namespace=foo %s /tmp/prefixed.git' +---------- + +SECURITY +-------- + +Anyone with access to any namespace within a repository can potentially +access objects from any other namespace stored in the same repository. +You can't directly say "give me object ABCD" if you don't have a ref to +it, but you can do some other sneaky things like: + +.

Requesting other refs, claiming that you have ABCD, at which point the + server may generate deltas against ABCD. + +None of this causes a problem if you only host public repositories, or +if everyone who may read one namespace may also read everything in every +other namespace (for instance, if everyone in an organization has read +permission to every repository). diff --git a/Documentation/gitrepository-layout.txt b/Documentation/gitrepository-layout.txt index eb3d040783..5c891f1169 100644 --- a/Documentation/gitrepository-layout.txt +++ b/Documentation/gitrepository-layout.txt @@ -23,32 +23,25 @@ objects:: Object store associated with this repository.

You can set variables +using "`our $variable = value`"; text from a "#" character until the +end of a line is ignored. See *perlsyn*(1) for details. + +An example: + + # gitweb configuration file for http://git.example.org + # + our $projectroot = "/srv/git"; # FHS recommendation + our $site_name = 'Example.org >> Repos'; + + +The configuration file is used to override the default settings that +were built into gitweb at the time the 'gitweb.cgi' script was generated. + +While one could just alter the configuration settings in the gitweb +CGI itself, those changes would be lost upon upgrade. Configuration +settings might also be placed into a file in the same directory as the +CGI script with the default name 'gitweb_config.perl' -- allowing +one to have multiple gitweb instances with different configurations by +the use of symlinks. + +Note that some configuration can be controlled on per-repository rather than +gitweb-wide basis: see "Per-repository gitweb configuration" subsection on +linkgit:gitweb[1] manpage. + + +DISCUSSION +---------- +Gitweb reads configuration data from the following sources in the +following order: + + * built-in values (some set during build stage), + + * common system-wide configuration file (defaults to + '/etc/gitweb-common.conf'), + + * either per-instance configuration file (defaults to 'gitweb_config.perl' + in the same directory as the installed gitweb), or if it does not exists + then fallback system-wide configuration file (defaults to '/etc/gitweb.conf'). + +Values obtained in later configuration files override values obtained earlier +in the above sequence. + +Locations of the common system-wide configuration file, the fallback +system-wide configuration file and the per-instance configuration file +are defined at compile time using build-time Makefile configuration +variables, respectively `GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM` +and `GITWEB_CONFIG`. + +You can also override locations of gitweb configuration files during +runtime by setting the following environment variables: +`GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM` and `GITWEB_CONFIG` +to a non-empty value. + + +The syntax of the configuration files is that of Perl, since these files are +handled by sourcing them as fragments of Perl code (the language that +gitweb itself is written in). Variables are typically set using the +`our` qualifier (as in "`our $variable = <value>;`") to avoid syntax +errors if a new version of gitweb no longer uses a variable and therefore +stops declaring it. + +You can include other configuration file using read_config_file() +subroutine. For example, one might want to put gitweb configuration +related to access control for viewing repositories via Gitolite (one +of git repository management tools) in a separate file, e.g. in +'/etc/gitweb-gitolite.conf'. To include it, put + +-------------------------------------------------- +read_config_file("/etc/gitweb-gitolite.conf"); +-------------------------------------------------- + +somewhere in gitweb configuration file used, e.g. in per-installation +gitweb configuration file. Note that read_config_file() checks itself +that the file it reads exists, and does nothing if it is not found. +It also handles errors in included file. + + +The default configuration with no configuration file at all may work +perfectly well for some installations. Still, a configuration file is +useful for customizing or tweaking the behavior of gitweb in many ways, and +some optional features will not be present unless explicitly enabled using +the configurable `%features` variable (see also "Configuring gitweb +features" section below). + + +CONFIGURATION VARIABLES +----------------------- +Some configuration variables have their default values (embedded in the CGI +script) set during building gitweb -- if that is the case, this fact is put +in their description. See gitweb's 'INSTALL' file for instructions on building +and installing gitweb. + + +Location of repositories +~~~~~~~~~~~~~~~~~~~~~~~~ +The configuration variables described below control how gitweb finds +git repositories, and how repositories are displayed and accessed. + +See also "Repositories" and later subsections in linkgit:gitweb[1] manpage. + +$projectroot:: + Absolute filesystem path which will be prepended to project path; + the path to repository is `$projectroot/$project`. Set to + `$GITWEB_PROJECTROOT` during installation. This variable has to be + set correctly for gitweb to find repositories. ++ +For example, if `$projectroot` is set to "/srv/git" by putting the following +in gitweb config file: ++ +---------------------------------------------------------------------------- +our $projectroot = "/srv/git"; +---------------------------------------------------------------------------- ++ +then ++ +------------------------------------------------ +http://git.example.com/gitweb.cgi?p=foo/bar.git +------------------------------------------------ ++ +and its path_info based equivalent ++ +------------------------------------------------ +http://git.example.com/gitweb.cgi/foo/bar.git +------------------------------------------------ ++ +will map to the path '/srv/git/foo/bar.git' on the filesystem. + +$projects_list:: + Name of a plain text file listing projects, or a name of directory + to be scanned for projects. ++ +Project list files should list one project per line, with each line +having the following format ++ +----------------------------------------------------------------------------- +<URI-encoded filesystem path to repository> SP <URI-encoded repository owner> +----------------------------------------------------------------------------- ++ +The default value of this variable is determined by the `GITWEB_LIST` +makefile variable at installation time. If this variable is empty, gitweb +will fall back to scanning the `$projectroot` directory for repositories. + +$project_maxdepth:: + If `$projects_list` variable is unset, gitweb will recursively + scan filesystem for git repositories. The `$project_maxdepth` + is used to limit traversing depth, relative to `$projectroot` + (starting point); it means that directories which are further + from `$projectroot` than `$project_maxdepth` will be skipped. ++ +It is purely performance optimization, originally intended for MacOS X, +where recursive directory traversal is slow. Gitweb follows symbolic +links, but it detects cycles, ignoring any duplicate files and directories. ++ +The default value of this variable is determined by the build-time +configuration variable `GITWEB_PROJECT_MAXDEPTH`, which defaults to +2007. + +$export_ok:: + Show repository only if this file exists (in repository). Only + effective if this variable evaluates to true. Can be set when + building gitweb by setting `GITWEB_EXPORT_OK`. This path is + relative to `GIT_DIR`. git-daemon[1] uses 'git-daemon-export-ok', + unless started with `--export-all`. By default this variable is + not set, which means that this feature is turned off. + +$export_auth_hook:: + Function used to determine which repositories should be shown. + This subroutine should take one parameter, the full path to + a project, and if it returns true, that project will be included + in the projects list and can be accessed through gitweb as long + as it fulfills the other requirements described by $export_ok, + $projects_list, and $projects_maxdepth. Example: ++ +---------------------------------------------------------------------------- +our $export_auth_hook = sub { return -e "$_[0]/git-daemon-export-ok"; }; +---------------------------------------------------------------------------- ++ +though the above might be done by using `$export_ok` instead ++ +---------------------------------------------------------------------------- +our $export_ok = "git-daemon-export-ok"; +---------------------------------------------------------------------------- ++ +If not set (default), it means that this feature is disabled. ++ +See also more involved example in "Controlling access to git repositories" +subsection on linkgit:gitweb[1] manpage. + +$strict_export:: + Only allow viewing of repositories also shown on the overview page. + This for example makes `$gitweb_export_ok` file decide if repository is + available and not only if it is shown. If `$gitweb_list` points to + file with list of project, only those repositories listed would be + available for gitweb. Can be set during building gitweb via + `GITWEB_STRICT_EXPORT`. By default this variable is not set, which + means that you can directly access those repositories that are hidden + from projects list page (e.g. the are not listed in the $projects_list + file). + + +Finding files +~~~~~~~~~~~~~ +The following configuration variables tell gitweb where to find files. +The values of these variables are paths on the filesystem. + +$GIT:: + Core git executable to use. By default set to `$GIT_BINDIR/git`, which + in turn is by default set to `$(bindir)/git`. If you use git installed + from a binary package, you should usually set this to "/usr/bin/git". + This can just be "git" if your web server has a sensible PATH; from + security point of view it is better to use absolute path to git binary. + If you have multiple git versions installed it can be used to choose + which one to use. Must be (correctly) set for gitweb to be able to + work. + +$mimetypes_file:: + File to use for (filename extension based) guessing of MIME types before + trying '/etc/mime.types'. *NOTE* that this path, if relative, is taken + as relative to the current git repository, not to CGI script. If unset, + only '/etc/mime.types' is used (if present on filesystem). If no mimetypes + file is found, mimetype guessing based on extension of file is disabled. + Unset by default. + +$highlight_bin:: + Path to the highlight executable to use (it must be the one from + http://www.andre-simon.de[] due to assumptions about parameters and output). + By default set to 'highlight'; set it to full path to highlight + executable if it is not installed on your web server's PATH. + Note that 'highlight' feature must be set for gitweb to actually + use syntax hightlighting. ++ +*NOTE*: if you want to add support for new file type (supported by +"highlight" but not used by gitweb), you need to modify `%highlight_ext` +or `%highlight_basename`, depending on whether you detect type of file +based on extension (for example "sh") or on its basename (for example +"Makefile"). The keys of these hashes are extension and basename, +respectively, and value for given key is name of syntax to be passed via +`--syntax <syntax>` to highlighter. ++ +For example if repositories you are hosting use "phtml" extension for +PHP files, and you want to have correct syntax-highlighting for those +files, you can add the following to gitweb configuration: ++ +--------------------------------------------------------- +our %highlight_ext; +$highlight_ext{'phtml'} = 'php'; +--------------------------------------------------------- + + +Links and their targets +~~~~~~~~~~~~~~~~~~~~~~~ +The configuration variables described below configure some of gitweb links: +their target and their look (text or image), and where to find page +prerequisites (stylesheet, favicon, images, scripts). Usually they are left +at their default values, with the possible exception of `@stylesheets` +variable. + +@stylesheets:: + List of URIs of stylesheets (relative to the base URI of a page). You + might specify more than one stylesheet, for example to use "gitweb.css" + as base with site specific modifications in a separate stylesheet + to make it easier to upgrade gitweb. For example, you can add + a `site` stylesheet by putting ++ +---------------------------------------------------------------------------- +push @stylesheets, "gitweb-site.css"; +---------------------------------------------------------------------------- ++ +in the gitweb config file. Those values that are relative paths are +relative to base URI of gitweb. ++ +This list should contain the URI of gitweb's standard stylesheet. The default +URI of gitweb stylesheet can be set at build time using the `GITWEB_CSS` +makefile variable. Its default value is 'static/gitweb.css' +(or 'static/gitweb.min.css' if the `CSSMIN` variable is defined, +i.e. if CSS minifier is used during build). ++ +*Note*: there is also a legacy `$stylesheet` configuration variable, which was +used by older gitweb. If `$stylesheet` variable is defined, only CSS stylesheet +given by this variable is used by gitweb. + +$logo:: + Points to the location where you put 'git-logo.png' on your web + server, or to be more the generic URI of logo, 72x27 size). This image + is displayed in the top right corner of each gitweb page and used as + a logo for the Atom feed. Relative to the base URI of gitweb (as a path). + Can be adjusted when building gitweb using `GITWEB_LOGO` variable + By default set to 'static/git-logo.png'. + +$favicon:: + Points to the location where you put 'git-favicon.png' on your web + server, or to be more the generic URI of favicon, which will be served + as "image/png" type. Web browsers that support favicons (website icons) + may display them in the browser's URL bar and next to the site name in + bookmarks. Relative to the base URI of gitweb. Can be adjusted at + build time using `GITWEB_FAVICON` variable. + By default set to 'static/git-favicon.png'. + +$javascript:: + Points to the location where you put 'gitweb.js' on your web server, + or to be more generic the URI of JavaScript code used by gitweb. + Relative to the base URI of gitweb. Can be set at build time using + the `GITWEB_JS` build-time configuration variable. ++ +The default value is either 'static/gitweb.js', or 'static/gitweb.min.js' if +the `JSMIN` build variable was defined, i.e. if JavaScript minifier was used +at build time. *Note* that this single file is generated from multiple +individual JavaScript "modules". + +$home_link:: + Target of the home link on the top of all pages (the first part of view + "breadcrumbs"). By default it is set to the absolute URI of a current page + (to the value of `$my_uri` variable, or to "/" if `$my_uri` is undefined + or is an empty string). + +$home_link_str:: + Label for the "home link" at the top of all pages, leading to `$home_link` + (usually the main gitweb page, which contains the projects list). It is + used as the first component of gitweb's "breadcrumb trail": + `<home link> / <project> / <action>`. Can be set at build time using + the `GITWEB_HOME_LINK_STR` variable. By default it is set to "projects", + as this link leads to the list of projects. Other popular choice it to + set it to the name of site. + +$logo_url:: +$logo_label:: + URI and label (title) for the Git logo link (or your site logo, + if you chose to use different logo image). By default, these both + refer to git homepage, http://git-scm.com[]; in the past, they pointed + to git documentation at http://www.kernel.org[]. + + +Changing gitweb's look +~~~~~~~~~~~~~~~~~~~~~~ +You can adjust how pages generated by gitweb look using the variables described +below. You can change the site name, add common headers and footers for all +pages, and add a description of this gitweb installation on its main page +(which is the projects list page), etc. + +$site_name:: + Name of your site or organization, to appear in page titles. Set it + to something descriptive for clearer bookmarks etc. If this variable + is not set or is, then gitweb uses the value of the `SERVER_NAME` + CGI environment variable, setting site name to "$SERVER_NAME Git", + or "Untitled Git" if this variable is not set (e.g. if running gitweb + as standalone script). ++ +Can be set using the `GITWEB_SITENAME` at build time. Unset by default. + +$site_html_head_string:: + HTML snippet to be included in the <head> section of each page. + Can be set using `GITWEB_SITE_HTML_HEAD_STRING` at build time. + No default value. + +$site_header:: + Name of a file with HTML to be included at the top of each page. + Relative to the directory containing the 'gitweb.cgi' script. + Can be set using `GITWEB_SITE_HEADER` at build time.

Relative to + the directory containing the gitweb.cgi script. Default value + can be adjusted during build time using `GITWEB_HOMETEXT` variable. + By default set to 'indextext.html'. + +$projects_list_description_width:: + The width (in characters) of the "Description" column of the projects list. + Longer descriptions will be truncated (trying to cut at word boundary); + the full description is available in the 'title' attribute (usually shown on + mouseover). The default is 25, which might be too small if you + use long project descriptions. + +$default_projects_order:: + Default value of ordering of projects on projects list page, which + means the ordering used if you don't explicitly sort projects list + (if there is no "o" CGI query parameter in the URL). Valid values + are "none" (unsorted), "project" (projects are by project name, + i.e. path to repository relative to `$projectroot`), "descr" + (project description), "owner", and "age" (by date of most current + commit). ++ +Default value is "project". Unknown value means unsorted. + + +Changing gitweb's behavior +~~~~~~~~~~~~~~~~~~~~~~~~~~ +These configuration variables control _internal_ gitweb behavior. + +$default_blob_plain_mimetype:: + Default mimetype for the blob_plain (raw) view, if mimetype checking + doesn't result in some other type; by default "text/plain". + Gitweb guesses mimetype of a file to display based on extension + of its filename, using `$mimetypes_file` (if set and file exists) + and '/etc/mime.types' files (see *mime.types*(5) manpage; only + filename extension rules are supported by gitweb). + +$default_text_plain_charset:: + Default charset for text files. If this is not set, the web server + configuration will be used. Unset by default. + +$fallback_encoding:: + Gitweb assumes this charset when a line contains non-UTF-8 characters. + The fallback decoding is used without error checking, so it can be even + "utf-8". The value must be a valid encoding; see the *Encoding::Supported*(3pm) + man page for a list. The default is "latin1", aka. "iso-8859-1". + +@diff_opts:: + Rename detection options for git-diff and git-diff-tree. The default is + (\'-M'); set it to (\'-C') or (\'-C', \'-C') to also detect copies, + or set it to () i.e. empty list if you don't want to have renames + detection. ++ +*Note* that rename and especially copy detection can be quite +CPU-intensive. Note also that non git tools can have problems with +patches generated with options mentioned above, especially when they +involve file copies (\'-C') or criss-cross renames (\'-B'). + + +Some optional features and policies +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Most of features are configured via `%feature` hash; however some of extra +gitweb features can be turned on and configured using variables described +below. This list beside configuration variables that control how gitweb +looks does contain variables configuring administrative side of gitweb +(e.g. cross-site scripting prevention; admittedly this as side effect +affects how "summary" pages look like, or load limiting). + +@git_base_url_list:: + List of git base URLs. These URLs are used to generate URLs + describing from where to fetch a project, which are shown on + project summary page. The full fetch URL is "`$git_base_url/$project`", + for each element of this list. You can set up multiple base URLs + (for example one for `git://` protocol, and one for `http://` + protocol). ++ +Note that per repository configuration can be set in '$GIT_DIR/cloneurl' +file, or as values of multi-value `gitweb.url` configuration variable in +project config. Per-repository configuration takes precedence over value +composed from `@git_base_url_list` elements and project name. ++ +You can setup one single value (single entry/item in this list) at build +time by setting the `GITWEB_BASE_URL` built-time configuration variable. +By default it is set to (), i.e. an empty list. This means that gitweb +would not try to create project URL (to fetch) from project name. + +$projects_list_group_categories:: + Whether to enables the grouping of projects by category on the project + list page. The category of a project is determined by the + `$GIT_DIR/category` file or the `gitweb.category` variable in each + repository's configuration. Disabled by default (set to 0). + +$project_list_default_category:: + Default category for projects for which none is specified. If this is + set to the empty string, such projects will remain uncategorized and + listed at the top, above categorized projects. Used only if project + categories are enabled, which means if `$projects_list_group_categories` + is true. By default set to "" (empty string). + +$prevent_xss:: + If true, some gitweb features are disabled to prevent content in + repositories from launching cross-site scripting (XSS) attacks. Set this + to true if you don't trust the content of your repositories. + False by default (set to 0). + +$maxload:: + Used to set the maximum load that we will still respond to gitweb queries. + If the server load exceeds this value then gitweb will return + "503 Service Unavailable" error. The server load is taken to be 0 + if gitweb cannot determine its value. Currently it works only on Linux, + where it uses '/proc/loadavg'; the load there is the number of active + tasks on the system -- processes that are actually running -- averaged + over the last minute. ++ +Set `$maxload` to undefined value (`undef`) to turn this feature off. +The default value is 300. + +$per_request_config:: + If this is set to code reference, it will be run once for each request. + You can set parts of configuration that change per session this way. + For example, one might use the following code in a gitweb configuration + file ++ +-------------------------------------------------------------------------------- +our $per_request_config = sub { + $ENV{GL_USER} = $cgi->remote_user || "gitweb"; +}; +-------------------------------------------------------------------------------- ++ +If `$per_request_config` is not a code reference, it is interpreted as boolean +value. If it is true gitweb will process config files once per request, +and if it is false gitweb will process config files only once, each time it +is executed. True by default (set to 1). ++ +*NOTE*: `$my_url`, `$my_uri`, and `$base_url` are overwritten with their default +values before every request, so if you want to change them, be sure to set +this variable to true or a code reference effecting the desired changes. ++ +This variable matters only when using persistent web environments that +serve multiple requests using single gitweb instance, like mod_perl, +FastCGI or Plackup. + + +Other variables +~~~~~~~~~~~~~~~ +Usually you should not need to change (adjust) any of configuration +variables described below; they should be automatically set by gitweb to +correct value. + + +$version:: + Gitweb version, set automatically when creating gitweb.cgi from + gitweb.perl. You might want to modify it if you are running modified + gitweb, for example ++ +--------------------------------------------------- +our $version .= " with caching"; +--------------------------------------------------- ++ +if you run modified version of gitweb with caching support. This variable +is purely informational, used e.g. in the "generator" meta header in HTML +header. + +$my_url:: +$my_uri:: + Full URL and absolute URL of the gitweb script; + in earlier versions of gitweb you might have need to set those + variables, but now there should be no need to do it. See + `$per_request_config` if you need to set them still. + +$base_url:: + Base URL for relative URLs in pages generated by gitweb, + (e.g. `$logo`, `$favicon`, `@stylesheets` if they are relative URLs), + needed and used '<base href="$base_url">' only for URLs with nonempty + PATH_INFO. Usually gitweb sets its value correctly, + and there is no need to set this variable, e.g. to $my_uri or "/". + See `$per_request_config` if you need to override it anyway. + + +CONFIGURING GITWEB FEATURES +--------------------------- +Many gitweb features can be enabled (or disabled) and configured using the +`%feature` hash. Names of gitweb features are keys of this hash. + +Each `%feature` hash element is a hash reference and has the following +structure: +---------------------------------------------------------------------- +"<feature_name>" => { + "sub" => <feature-sub (subroutine)>, + "override" => <allow-override (boolean)>, + "default" => [ <options>... ] +}, +---------------------------------------------------------------------- +Some features cannot be overridden per project. For those +features the structure of appropriate `%feature` hash element has a simpler +form: +---------------------------------------------------------------------- +"<feature_name>" => { + "override" => 0, + "default" => [ <options>... ] +}, +---------------------------------------------------------------------- +As one can see it lacks the \'sub' element. + +The meaning of each part of feature configuration is described +below: + +default:: + List (array reference) of feature parameters (if there are any), + used also to toggle (enable or disable) given feature. ++ +Note that it is currently *always* an array reference, even if +feature doesn't accept any configuration parameters, and \'default' +is used only to turn it on or off. In such case you turn feature on +by setting this element to `[1]`, and torn it off by setting it to +`[0]`. See also the passage about the "blame" feature in the "Examples" +section. ++ +To disable features that accept parameters (are configurable), you +need to set this element to empty list i.e. `[]`. + +override:: + If this field has a true value then the given feature is + overriddable, which means that it can be configured + (or enabled/disabled) on a per-repository basis. ++ +Usually given "<feature>" is configurable via the `gitweb.<feature>` +config variable in the per-repository git configuration file. ++ +*Note* that no feature is overriddable by default. + +sub:: + Internal detail of implementation. What is important is that + if this field is not present then per-repository override for + given feature is not supported. ++ +You wouldn't need to ever change it in gitweb config file. + + +Features in `%feature` +~~~~~~~~~~~~~~~~~~~~~~ +The gitweb features that are configurable via `%feature` hash are listed +below. This should be a complete list, but ultimately the authoritative +and complete list is in gitweb.cgi source code, with features described +in the comments. + +blame:: + Enable the "blame" and "blame_incremental" blob views, showing for + each line the last commit that modified it; see linkgit:git-blame[1]. + This can be very CPU-intensive and is therefore disabled by default. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.blame` configuration variable (boolean). + +snapshot:: + Enable and configure the "snapshot" action, which allows user to + download a compressed archive of any tree or commit, as produced + by linkgit:git-archive[1] and possibly additionally compressed. + This can potentially generate high traffic if you have large project. ++ +The value of \'default' is a list of names of snapshot formats, +defined in `%known_snapshot_formats` hash, that you wish to offer. +Supported formats include "tgz", "tbz2", "txz" (gzip/bzip2/xz +compressed tar archive) and "zip"; please consult gitweb sources for +a definitive list. By default only "tgz" is offered. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.blame` configuration variable, which contains +a comma separated list of formats or "none" to disable snapshots. +Unknown values are ignored. + +grep:: + Enable grep search, which lists the files in currently selected + tree (directory) containing the given string; see linkgit:git-grep[1]. + This can be potentially CPU-intensive, of course. Enabled by default. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.grep` configuration variable (boolean). + +pickaxe:: + Enable the so called pickaxe search, which will list the commits + that introduced or removed a given string in a file. This can be + practical and quite faster alternative to "blame" action, but it is + still potentially CPU-intensive. Enabled by default. ++ +The pickaxe search is described in linkgit:git-log[1] (the +description of `-S<string>` option, which refers to pickaxe entry in +linkgit:gitdiffcore[7] for more details). ++ +This feature can be configured on a per-repository basis by setting +repository's `gitweb.pickaxe` configuration variable (boolean). + +show-sizes:: + Enable showing size of blobs (ordinary files) in a "tree" view, in a + separate column, similar to what `ls -l` does; see description of + `-l` option in linkgit:git-ls-tree[1] manpage. This costs a bit of + I/O. Enabled by default. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.showsizes` configuration variable (boolean). + +patches:: + Enable and configure "patches" view, which displays list of commits in email + (plain text) output format; see also linkgit:git-format-patch[1]. + The value is the maximum number of patches in a patchset generated + in "patches" view. Set the 'default' field to a list containing single + item of or to an empty list to disable patch view, or to a list + containing a single negative number to remove any limit. + Default value is 16. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.patches` configuration variable (integer). + +avatar:: + Avatar support. When this feature is enabled, views such as + "shortlog" or "commit" will display an avatar associated with + the email of each committer and author. ++ +Currently available providers are *"gravatar"* and *"picon"*. +Only one provider at a time can be selected ('default' is one element list). +If an unknown provider is specified, the feature is disabled. +*Note* that some providers might require extra Perl packages to be +installed; see 'gitweb/INSTALL' for more details. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.avatar` configuration variable. ++ +See also `%avatar_size` with pixel sizes for icons and avatars +("default" is used for one-line like "log" and "shortlog", "double" +is used for two-line like "commit", "commitdiff" or "tag"). If the +default font sizes or lineheights are changed (e.g. via adding extra +CSS stylesheet in `@stylesheets`), it may be appropriate to change +these values. + +highlight:: + Server-side syntax highlight support in "blob" view. It requires + `$highlight_bin` program to be available (see the description of + this variable in the "Configuration variables" section above), + and therefore is disabled by default. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.highlight` configuration variable (boolean). + +remote_heads:: + Enable displaying remote heads (remote-tracking branches) in the "heads" + list. In most cases the list of remote-tracking branches is an + unnecessary internal private detail, and this feature is therefore + disabled by default. linkgit:git-instaweb[1], which is usually used + to browse local repositories, enables and uses this feature. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.remote_heads` configuration variable (boolean). + + +The remaining features cannot be overridden on a per project basis. + +search:: + Enable text search, which will list the commits which match author, + committer or commit text to a given string; see the description of + `--author`, `--committer` and `--grep` options in linkgit:git-log[1] + manpage. Enabled by default. ++ +Project specific override is not supported. + +forks:: + If this feature is enabled, gitweb considers projects in + subdirectories of project root (basename) to be forks of existing + projects. For each project `$projname.git`, projects in the + `$projname/` directory and its subdirectories will not be + shown in the main projects list. Instead, a \'+' mark is shown + next to `$projname`, which links to a "forks" view that lists all + the forks (all projects in `$projname/` subdirectory). Additionally + a "forks" view for a project is linked from project summary page. ++ +If the project list is taken from a file (`$projects_list` points to a +file), forks are only recognized if they are listed after the main project +in that file. ++ +Project specific override is not supported. + +actions:: + Insert custom links to the action bar of all project pages. This + allows you to link to third-party scripts integrating into gitweb. ++ +The "default" value consists of a list of triplets in the form +`("<label>", "<link>", "<position>")` where "position" is the label +after which to insert the link, "link" is a format string where `%n` +expands to the project name, `%f` to the project path within the +filesystem (i.e. "$projectroot/$project"), `%h` to the current hash +(\'h' gitweb parameter) and `%b` to the current hash base +(\'hb' gitweb parameter); `%%` expands to \'%'. ++ +For example, at the time this page was written, the http://repo.or.cz[] +git hosting site set it to the following to enable graphical log +(using the third party tool *git-browser*): ++ +---------------------------------------------------------------------- +$feature{'actions'}{'default'} = + [ ('graphiclog', '/git-browser/by-commit.html?r=%n', 'summary')]; +---------------------------------------------------------------------- ++ +This adds a link titled "graphiclog" after the "summary" link, leading to +`git-browser` script, passing `r=<project>` as a query parameter. ++ +Project specific override is not supported. + +timed:: + Enable displaying how much time and how many git commands it took to + generate and display each page in the page footer (at the bottom of + page). For example the footer might contain: "This page took 6.53325 + seconds and 13 git commands to generate." Disabled by default. ++ +Project specific override is not supported. + +javascript-timezone:: + Enable and configure the ability to change a common timezone for dates + in gitweb output via JavaScript. Dates in gitweb output include + authordate and committerdate in "commit", "commitdiff" and "log" + views, and taggerdate in "tag" view. Enabled by default. ++ +The value is a list of three values: a default timezone (for if the client +hasn't selected some other timezone and saved it in a cookie), a name of cookie +where to store selected timezone, and a CSS class used to mark up +dates for manipulation. If you want to turn this feature off, set "default" +to empty list: `[]`. ++ +Typical gitweb config files will only change starting (default) timezone, +and leave other elements at their default values: ++ +--------------------------------------------------------------------------- +$feature{'javascript-timezone'}{'default'}[0] = "utc"; +--------------------------------------------------------------------------- ++ +The example configuration presented here is guaranteed to be backwards +and forward compatible. ++ +Timezone values can be "local" (for local timezone that browser uses), "utc" +(what gitweb uses when JavaScript or this feature is disabled), or numerical +timezones in the form of "+/-HHMM", such as "+0200". ++ +Project specific override is not supported. + + +EXAMPLES +-------- + +To enable blame, pickaxe search, and snapshot support (allowing "tar.gz" and +"zip" snapshots), while allowing individual projects to turn them off, put +the following in your GITWEB_CONFIG file: + + $feature{'blame'}{'default'} = [1]; + $feature{'blame'}{'override'} = 1; + + $feature{'pickaxe'}{'default'} = [1]; + $feature{'pickaxe'}{'override'} = 1; + + $feature{'snapshot'}{'default'} = ['zip', 'tgz']; + $feature{'snapshot'}{'override'} = 1; + +If you allow overriding for the snapshot feature, you can specify which +snapshot formats are globally disabled. You can also add any command line +options you want (such as setting the compression level). For instance, you +can disable Zip compressed snapshots and set *gzip*(1) to run at level 6 by +adding the following lines to your gitweb configuration file: + + $known_snapshot_formats{'zip'}{'disabled'} = 1; + $known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6']; + +ENVIRONMENT +----------- +The location of per-instance and system-wide configuration files can be +overridden using the following environment variables: + +GITWEB_CONFIG:: + Sets location of per-instance configuration file. +GITWEB_CONFIG_SYSTEM:: + Sets location of fallback system-wide configuration file. + This file is read only if per-instance one does not exist. +GITWEB_CONFIG_COMMON:: + Sets location of common system-wide configuration file. + + +FILES +----- +gitweb_config.perl:: + This is default name of per-instance configuration file.

It's features include: + +* Viewing multiple Git repositories with common root. +* Browsing every revision of the repository. +* Viewing the contents of files in the repository at any revision. +* Viewing the revision log of branches, history of files and directories, + see what was changed when, by who. +* Viewing the blame/annotation details of any file (if enabled). +* Generating RSS and Atom feeds of commits, for any branch. + The feeds are auto-discoverable in modern web browsers. +* Viewing everything that was changed in a revision, and step through + revisions one at a time, viewing the history of the repository. +* Finding commits which commit messages matches given search term. + +See http://git.kernel.org/?p=git/git.git;a=tree;f=gitweb[] or +http://repo.or.cz/w/git.git/tree/HEAD:/gitweb/[] for gitweb source code, +browsed using gitweb itself. + + +CONFIGURATION +------------- +Various aspects of gitweb's behavior can be controlled through the configuration +file 'gitweb_config.perl' or '/etc/gitweb.conf'. See the linkgit:gitweb.conf[5] +for details. + +Repositories +~~~~~~~~~~~~ +Gitweb can show information from one or more Git repositories. These +repositories have to be all on local filesystem, and have to share common +repository root, i.e. be all under a single parent repository (but see also +"Advanced web server setup" section, "Webserver configuration with multiple +projects' root" subsection). + +----------------------------------------------------------------------- +our $projectroot = '/path/to/parent/directory'; +----------------------------------------------------------------------- + +The default value for `$projectroot` is '/pub/git'. You can change it during +building gitweb via `GITWEB_PROJECTROOT` build configuration variable. + +By default all git repositories under `$projectroot` are visible and available +to gitweb. The list of projects is generated by default by scanning the +`$projectroot` directory for git repositories (for object databases to be +more exact; gitweb is not interested in a working area, and is best suited +to showing "bare" repositories). + +The name of repository in gitweb is path to it's `$GIT_DIR` (it's object +database) relative to `$projectroot`. Therefore the repository $repo can be +found at "$projectroot/$repo". + + +Projects list file format +~~~~~~~~~~~~~~~~~~~~~~~~~ +Instead of having gitweb find repositories by scanning filesystem +starting from $projectroot, you can provide a pre-generated list of +visible projects by setting `$projects_list` to point to a plain text +file with a list of projects (with some additional info). + +This file uses the following format: + +* One record (for project / repository) per line; does not support line +continuation (newline escaping). + +* Leading and trailing whitespace are ignored. + +* Whitespace separated fields; any run of whitespace can be used as field +separator (rules for Perl's "`split(" ", $line)`"). + +* Fields use modified URI encoding, defined in RFC 3986, section 2.1 +(Percent-Encoding), or rather "Query string encoding" (see +link:http://en.wikipedia.org/wiki/Query_string#URL_encoding[]), the difference +being that SP (" ") can be encoded as "{plus}" (and therefore "{plus}" has to be +also percent-encoded). ++ +Reserved characters are: "%" (used for encoding), "{plus}" (can be used to +encode SPACE), all whitespace characters as defined in Perl, including SP, +TAB and LF, (used to separate fields in a record). + +* Currently recognized fields are: +<repository path>:: + path to repository GIT_DIR, relative to `$projectroot` +<repository owner>:: + displayed as repository owner, preferably full name, or email, + or both + +You can generate the projects list index file using the project_index action +(the 'TXT' link on projects list page) directly from gitweb; see also +"Generating projects list using gitweb" section below. + +Example contents: +----------------------------------------------------------------------- +foo.git Joe+R+Hacker+<joe@example.com> +foo/bar.git O+W+Ner+<owner@example.org> +----------------------------------------------------------------------- + + +By default this file controls only which projects are *visible* on projects +list page (note that entries that do not point to correctly recognized git +repositories won't be displayed by gitweb). Even if a project is not +visible on projects list page, you can view it nevertheless by hand-crafting +a gitweb URL. By setting `$strict_export` configuration variable (see +linkgit:gitweb.conf[5]) to true value you can allow viewing only of +repositories also shown on the overview page (i.e. only projects explicitly +listed in projects list file will be accessible). + + +Generating projects list using gitweb +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +We assume that GITWEB_CONFIG has its default Makefile value, namely +'gitweb_config.perl'. Put the following in 'gitweb_make_index.perl' file: +---------------------------------------------------------------------------- +read_config_file("gitweb_config.perl"); +$projects_list = $projectroot; +---------------------------------------------------------------------------- + +Then create the following script to get list of project in the format +suitable for GITWEB_LIST build configuration variable (or +`$projects_list` variable in gitweb config): + +---------------------------------------------------------------------------- +#!/bin/sh + +export GITWEB_CONFIG="gitweb_make_index.perl" +export GATEWAY_INTERFACE="CGI/1.1" +export HTTP_ACCEPT="*/*" +export REQUEST_METHOD="GET" +export QUERY_STRING="a=project_index" + +perl -- /var/www/cgi-bin/gitweb.cgi +---------------------------------------------------------------------------- + +Run this script and save its output to a file. This file could then be used +as projects list file, which means that you can set `$projects_list` to its +filename. + + +Controlling access to git repositories +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +By default all git repositories under `$projectroot` are visible and +available to gitweb. You can however configure how gitweb controls access +to repositories. + +* As described in "Projects list file format" section, you can control which +projects are *visible* by selectively including repositories in projects +list file, and setting `$projects_list` gitweb configuration variable to +point to it. With `$strict_export` set, projects list file can be used to +control which repositories are *available* as well. + +* You can configure gitweb to only list and allow viewing of the explicitly +exported repositories, via `$export_ok` variable in gitweb config file; see +linkgit:gitweb.conf[5] manpage. If it evaluates to true, gitweb shows +repositories only if this file named by `$export_ok` exists in its object +database (if directory has the magic file named `$export_ok`). ++ +For example linkgit:git-daemon[1] by default (unless `--export-all` option +is used) allows pulling only for those repositories that have +'git-daemon-export-ok' file. Adding ++ +-------------------------------------------------------------------------- +our $export_ok = "git-daemon-export-ok"; +-------------------------------------------------------------------------- ++ +makes gitweb show and allow access only to those repositories that can be +fetched from via `git://` protocol. + +* Finally, it is possible to specify an arbitrary perl subroutine that will +be called for each repository to determine if it can be exported. The +subroutine receives an absolute path to the project (repository) as its only +parameter (i.e. "$projectroot/$project"). ++ +For example, if you use mod_perl to run the script, and have dumb +HTTP protocol authentication configured for your repositories, you +can use the following hook to allow access only if the user is +authorized to read the files: ++ +-------------------------------------------------------------------------- +$export_auth_hook = sub { + use Apache2::SubRequest (); + use Apache2::Const -compile => qw(HTTP_OK); + my $path = "$_[0]/HEAD"; + my $r = Apache2::RequestUtil->request; + my $sub = $r->lookup_file($path); + return $sub->filename eq $path + && $sub->status == Apache2::Const::HTTP_OK; +}; +-------------------------------------------------------------------------- + + +Per-repository gitweb configuration +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +You can configure individual repositories shown in gitweb by creating file +in the 'GIT_DIR' of git repository, or by setting some repo configuration +variable (in 'GIT_DIR/config', see linkgit:git-config[1]). + +You can use the following files in repository: + +README.html:: + A html file (HTML fragment) which is included on the gitweb project + "summary" page inside `<div>` block element. You can use it for longer + description of a project, to provide links (for example to project's + homepage), etc. This is recognized only if XSS prevention is off + (`$prevent_xss` is false, see linkgit:gitweb.conf[5]); a way to include + a README safely when XSS prevention is on may be worked out in the + future. + +description (or `gitweb.description`):: + Short (shortened to `$projects_list_description_width` in the projects + list page, which is 25 characters by default; see + linkgit:gitweb.conf[5]) single line description of a project (of a + repository). Plain text file; HTML will be escaped. By default set to ++ +------------------------------------------------------------------------------- +Unnamed repository; edit this file to name it for gitweb. +------------------------------------------------------------------------------- ++ +from the template during repository creation, usually installed in +'/usr/share/git-core/templates/'. You can use the `gitweb.description` repo +configuration variable, but the file takes precedence. + +category (or `gitweb.category`):: + Singe line category of a project, used to group projects if + `$projects_list_group_categories` is enabled. By default (file and + configuration variable absent), uncategorized projects are put in the + `$project_list_default_category` category. You can use the + `gitweb.category` repo configuration variable, but the file takes + precedence. ++ +The configuration variables `$projects_list_group_categories` and +`$project_list_default_category` are described in linkgit:gitweb.conf[5] + +cloneurl (or multiple-valued `gitweb.url`):: + File with repository URL (used for clone and fetch), one per line. + Displayed in the project summary page. You can use multiple-valued + `gitweb.url` repository configuration variable for that, but the file + takes precedence. ++ +This is per-repository enhancement / version of global prefix-based +`@git_base_url_list` gitweb configuration variable (see +linkgit:gitweb.conf[5]). + +gitweb.owner:: + You can use the `gitweb.owner` repository configuration variable to set + repository's owner. It is displayed in the project list and summary + page. ++ +If it's not set, filesystem directory's owner is used (via GECOS field, +i.e. real name field from *getpwuid*(3)) if `$projects_list` is unset +(gitweb scans `$projectroot` for repositories); if `$projects_list` +points to file with list of repositories, then project owner defaults to +value from this file for given repository. + +various `gitweb.*` config variables (in config):: + Read description of `%feature` hash for detailed list, and descriptions. + See also "Configuring gitweb features" section in linkgit:gitweb.conf[5] + + +ACTIONS, AND URLS +----------------- +Gitweb can use path_info (component) based URLs, or it can pass all necessary +information via query parameters. The typical gitweb URLs are broken down in to +five components: + +----------------------------------------------------------------------- +.../gitweb.cgi/<repo>/<action>/<revision>:/<path>?<arguments> +----------------------------------------------------------------------- + +repo:: + The repository the action will be performed on. ++ +All actions except for those that list all available projects, +in whatever form, require this parameter. + +action:: + The action that will be run. Defaults to 'projects_list' if repo + is not set, and to 'summary' otherwise. + +revision:: + Revision shown. Defaults to HEAD. + +path:: + The path within the <repository> that the action is performed on, + for those actions that require it. + +arguments:: + Any arguments that control the behaviour of the action. + +Some actions require or allow to specify two revisions, and sometimes even two +pathnames. In most general form such path_info (component) based gitweb URL +looks like this: + +----------------------------------------------------------------------- +.../gitweb.cgi/<repo>/<action>/<revision_from>:/<path_from>..<revision_to>:/<path_to>?<arguments> +----------------------------------------------------------------------- + + +Each action is implemented as a subroutine, and must be present in %actions +hash.

For example to enable 'blame' view add the following to gitweb +configuration file: + +----------------------------------------------------------------------- +$feature{'blame'}{'default'} = [1]; +----------------------------------------------------------------------- + + +Actions: +~~~~~~~~ +The standard actions are: + +project_list:: + Lists the available Git repositories. This is the default command if no + repository is specified in the URL. + +summary:: + Displays summary about given repository. This is the default command if + no action is specified in URL, and only repository is specified. + +heads:: +remotes:: + Lists all local or all remote-tracking branches in given repository. ++ +The latter is not available by default, unless configured. + +tags:: + List all tags (lightweight and annotated) in given repository. + +blob:: +tree:: + Shows the files and directories in a given repository path, at given + revision. This is default command if no action is specified in the URL, + and path is given. + +blob_plain:: + Returns the raw data for the file in given repository, at given path and + revision. Links to this action are marked 'raw'. + +blobdiff:: + Shows the difference between two revisions of the same file. + +blame:: +blame_incremental:: + Shows the blame (also called annotation) information for a file. On a + per line basis it shows the revision in which that line was last changed + and the user that committed the change. The incremental version (which + if configured is used automatically when JavaScript is enabled) uses + Ajax to incrementally add blame info to the contents of given file. ++ +This action is disabled by default for performance reasons. + +commit:: +commitdiff:: + Shows information about a specific commit in a repository. The 'commit' + view shows information about commit in more detail, the 'commitdiff' + action shows changeset for given commit. + +patch:: + Returns the commit in plain text mail format, suitable for applying with + linkgit:git-am[1]. + +tag:: + Display specific annotated tag (tag object). + +log:: +shortlog:: + Shows log information (commit message or just commit subject) for a + given branch (starting from given revision). ++ +The 'shortlog' view is more compact; it shows one commit per line. + +history:: + Shows history of the file or directory in a given repository path, + starting from given revision (defaults to HEAD, i.e. default branch). ++ +This view is similar to 'shortlog' view. + +rss:: +atom:: + Generates an RSS (or Atom) feed of changes to repository. + + +WEBSERVER CONFIGURATION +----------------------- +This section explains how to configure some common webservers to run gitweb. In +all cases, `/path/to/gitweb` in the examples is the directory you ran installed +gitweb in, and contains `gitweb_config.perl`. + +If you've configured a web server that isn't listed here for gitweb, please send +in the instructions so they can be included in a future release. + +Apache as CGI +~~~~~~~~~~~~~ +Apache must be configured to support CGI scripts in the directory in +which gitweb is installed. Let's assume that it is '/var/www/cgi-bin' +directory. + +----------------------------------------------------------------------- +ScriptAlias /cgi-bin/ "/var/www/cgi-bin/" + +<Directory "/var/www/cgi-bin"> + Options Indexes FollowSymlinks ExecCGI + AllowOverride None + Order allow,deny + Allow from all +</Directory> +----------------------------------------------------------------------- + +With that configuration the full path to browse repositories would be: + + http://server/cgi-bin/gitweb.cgi + +Apache with mod_perl, via ModPerl::Registry +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +You can use mod_perl with gitweb. You must install Apache::Registry +(for mod_perl 1.x) or ModPerl::Registry (for mod_perl 2.x) to enable +this support. + +Assuming that gitweb is installed to '/var/www/perl', the following +Apache configuration (for mod_perl 2.x) is suitable. + +----------------------------------------------------------------------- +Alias /perl "/var/www/perl" + +<Directory "/var/www/perl"> + SetHandler perl-script + PerlResponseHandler ModPerl::Registry + PerlOptions +ParseHeaders + Options Indexes FollowSymlinks +ExecCGI + AllowOverride None + Order allow,deny + Allow from all +</Directory> +----------------------------------------------------------------------- + +With that configuration the full path to browse repositories would be: + + http://server/perl/gitweb.cgi + +Apache with FastCGI +~~~~~~~~~~~~~~~~~~~ +Gitweb works with Apache and FastCGI. First you need to rename, copy +or symlink gitweb.cgi to gitweb.fcgi. Let's assume that gitweb is +installed in '/usr/share/gitweb' directory. The following Apache +configuration is suitable (UNTESTED!) + +----------------------------------------------------------------------- +FastCgiServer /usr/share/gitweb/gitweb.cgi +ScriptAlias /gitweb /usr/share/gitweb/gitweb.cgi + +Alias /gitweb/static /usr/share/gitweb/static +<Directory /usr/share/gitweb/static> + SetHandler default-handler +</Directory> +----------------------------------------------------------------------- + +With that configuration the full path to browse repositories would be: + + http://server/gitweb + + +ADVANCED WEB SERVER SETUP +------------------------- +All of those examples use request rewriting, and need `mod_rewrite` +(or equivalent; examples below are written for Apache). + +Single URL for gitweb and for fetching +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +If you want to have one URL for both gitweb and your `http://` +repositories, you can configure Apache like this: + +----------------------------------------------------------------------- +<VirtualHost *:80> + ServerName git.example.org + DocumentRoot /pub/git + SetEnv GITWEB_CONFIG /etc/gitweb.conf + + # turning on mod rewrite + RewriteEngine on + + # make the front page an internal rewrite to the gitweb script + RewriteRule ^/$ /cgi-bin/gitweb.cgi + + # make access for "dumb clients" work + RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ \ + /cgi-bin/gitweb.cgi%{REQUEST_URI} [L,PT] +</VirtualHost> +----------------------------------------------------------------------- + +The above configuration expects your public repositories to live under +'/pub/git' and will serve them as `http://git.domain.org/dir-under-pub-git`, +both as cloneable GIT URL and as browseable gitweb interface. If you then +start your linkgit:git-daemon[1] with `--base-path=/pub/git --export-all` +then you can even use the `git://` URL with exactly the same path. + +Setting the environment variable `GITWEB_CONFIG` will tell gitweb to use the +named file (i.e. in this example '/etc/gitweb.conf') as a configuration for +gitweb. You don't really need it in above example; it is required only if +your configuration file is in different place than built-in (during +compiling gitweb) 'gitweb_config.perl' or '/etc/gitweb.conf'. See +linkgit:gitweb.conf[5] for details, especially information about precedence +rules. + +If you use the rewrite rules from the example you *might* also need +something like the following in your gitweb configuration file +('/etc/gitweb.conf' following example): +---------------------------------------------------------------------------- +@stylesheets = ("/some/absolute/path/gitweb.css"); +$my_uri = "/"; +$home_link = "/"; +$per_request_config = 1; +---------------------------------------------------------------------------- +Nowadays though gitweb should create HTML base tag when needed (to set base +URI for relative links), so it should work automatically. + + +Webserver configuration with multiple projects' root +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +If you want to use gitweb with several project roots you can edit your +Apache virtual host and gitweb configuration files in the following way. + +The virtual host configuration (in Apache configuration file) should look +like this: +-------------------------------------------------------------------------- +<VirtualHost *:80> + ServerName git.example.org + DocumentRoot /pub/git + SetEnv GITWEB_CONFIG /etc/gitweb.conf + + # turning on mod rewrite + RewriteEngine on + + # make the front page an internal rewrite to the gitweb script + RewriteRule ^/$ /cgi-bin/gitweb.cgi [QSA,L,PT] + + # look for a public_git folder in unix users' home + # http://git.example.org/~<user>/ + RewriteRule ^/\~([^\/]+)(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \ + [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT] + + # http://git.example.org/+<user>/ + #RewriteRule ^/\+([^\/]+)(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \ + [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT] + + # http://git.example.org/user/<user>/ + #RewriteRule ^/user/([^\/]+)/(gitweb.cgi)?$ /cgi-bin/gitweb.cgi \ + [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT] + + # defined list of project roots + RewriteRule ^/scm(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \ + [QSA,E=GITWEB_PROJECTROOT:/pub/scm/,L,PT] + RewriteRule ^/var(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \ + [QSA,E=GITWEB_PROJECTROOT:/var/git/,L,PT] + + # make access for "dumb clients" work + RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ \ + /cgi-bin/gitweb.cgi%{REQUEST_URI} [L,PT] +</VirtualHost> +-------------------------------------------------------------------------- + +Here actual project root is passed to gitweb via `GITWEB_PROJECT_ROOT` +environment variable from a web server, so you need to put the following +line in gitweb configuration file ('/etc/gitweb.conf' in above example): +-------------------------------------------------------------------------- +$projectroot = $ENV{'GITWEB_PROJECTROOT'} || "/pub/git"; +-------------------------------------------------------------------------- +*Note* that this requires to be set for each request, so either +`$per_request_config` must be false, or the above must be put in code +referenced by `$per_request_config`; + +These configurations enable two things. First, each unix user (`<user>`) of +the server will be able to browse through gitweb git repositories found in +'~/public_git/' with the following url: + + http://git.example.org/~<user>/ + +If you do not want this feature on your server just remove the second +rewrite rule. + +If you already use `mod_userdir` in your virtual host or you don't want to +use the \'~' as first character, just comment or remove the second rewrite +rule, and uncomment one of the following according to what you want. + +Second, repositories found in '/pub/scm/' and '/var/git/' will be accessible +through `http://git.example.org/scm/` and `http://git.example.org/var/`. +You can add as many project roots as you want by adding rewrite rules like +the third and the fourth. + + +PATH_INFO usage +~~~~~~~~~~~~~~~ +If you enable PATH_INFO usage in gitweb by putting +---------------------------------------------------------------------------- +$feature{'pathinfo'}{'default'} = [1]; +---------------------------------------------------------------------------- +in your gitweb configuration file, it is possible to set up your server so +that it consumes and produces URLs in the form + + http://git.example.com/project.git/shortlog/sometag + +i.e. without 'gitweb.cgi' part, by using a configuration such as the +following. This configuration assumes that '/var/www/gitweb' is the +DocumentRoot of your webserver, contains the gitweb.cgi script and +complementary static files (stylesheet, favicon, JavaScript): + +---------------------------------------------------------------------------- +<VirtualHost *:80> + ServerAlias git.example.com + + DocumentRoot /var/www/gitweb + + <Directory /var/www/gitweb> + Options ExecCGI + AddHandler cgi-script cgi + + DirectoryIndex gitweb.cgi + + RewriteEngine On + RewriteCond %{REQUEST_FILENAME} !-f + RewriteCond %{REQUEST_FILENAME} !-d + RewriteRule ^.* /gitweb.cgi/$0 [L,PT] + </Directory> +</VirtualHost> +---------------------------------------------------------------------------- +The rewrite rule guarantees that existing static files will be properly +served, whereas any other URL will be passed to gitweb as PATH_INFO +parameter. + +*Notice* that in this case you don't need special settings for +`@stylesheets`, `$my_uri` and `$home_link`, but you lose "dumb client" +access to your project .git dirs (described in "Single URL for gitweb and +for fetching" section). A possible workaround for the latter is the +following: in your project root dir (e.g. '/pub/git') have the projects +named *without* a .git extension (e.g. '/pub/git/project' instead of +'/pub/git/project.git') and configure Apache as follows: +---------------------------------------------------------------------------- +<VirtualHost *:80> + ServerAlias git.example.com + + DocumentRoot /var/www/gitweb + + AliasMatch ^(/.*?)(\.git)(/.*)?$ /pub/git$1$3 + <Directory /var/www/gitweb> + Options ExecCGI + AddHandler cgi-script cgi + + DirectoryIndex gitweb.cgi + + RewriteEngine On + RewriteCond %{REQUEST_FILENAME} !-f + RewriteCond %{REQUEST_FILENAME} !-d + RewriteRule ^.* /gitweb.cgi/$0 [L,PT] + </Directory> +</VirtualHost> +---------------------------------------------------------------------------- + +The additional AliasMatch makes it so that + + http://git.example.com/project.git + +will give raw access to the project's git dir (so that the project can be +cloned), while + + http://git.example.com/project + +will provide human-friendly gitweb access. + +This solution is not 100% bulletproof, in the sense that if some project has +a named ref (branch, tag) starting with 'git/', then paths such as + + http://git.example.com/project/command/abranch..git/abranch + +will fail with a 404 error. + + +BUGS +---- +Please report any bugs or feature requests to git@vger.kernel.org, +putting "gitweb" in the subject of email. + +SEE ALSO +-------- +linkgit:gitweb.conf[5], linkgit:git-instaweb[1] + +'gitweb/README', 'gitweb/INSTALL' + +GIT +--- +Part of the linkgit:git[1] suite diff --git a/Documentation/howto/maintain-git.txt b/Documentation/howto/maintain-git.txt index d527b30770..8823a37067 100644 --- a/Documentation/howto/maintain-git.txt +++ b/Documentation/howto/maintain-git.txt @@ -176,7 +176,7 @@ by doing the following: - Update "What's cooking" message to review the updates to existing topics, newly added topics and graduated topics. - This step is helped with Meta/UWC script (where Meta/ contains + This step is helped with Meta/cook script (where Meta/ contains a checkout of the 'todo' branch). - Merge topics to 'next'.

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 <nitfol@example.com>" +------------ + +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 <nitfol@example.com>" + Merge: 406da78 703f05a + Author: Inte Grator <xyzzy@example.com> + 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 idea +is that you would use these pre-tested macros to solve a +very specific set of problems, and they would run fast. +Caution: no side-effects in arguments please!! They may be +evaluated MANY times!! + +These macros operate a stack of objects. Each object starts life +small, and may grow to maturity. (Consider building a word syllable +by syllable.) An object can move while it is growing. Once it has +been "finished" it never changes address again. So the "top of the +stack" is typically an immature growing object, while the rest of the +stack is of mature, fixed size and fixed address objects. + +These routines grab large chunks of memory, using a function you +supply, called `obstack_chunk_alloc'. On occasion, they free chunks, +by calling `obstack_chunk_free'. You must define them and declare +them before using any obstack macros. + +Each independent stack is represented by a `struct obstack'. +Each of the obstack macros expects a pointer to such a structure +as the first argument. + +One motivation for this package is the problem of growing char strings +in symbol tables. Unless you are "fascist pig with a read-only mind" +--Gosper's immortal quote from HAKMEM item 154, out of context--you +would not like to put any arbitrary upper limit on the length of your +symbols. + +In practice this often means you will build many short symbols and a +few long symbols. At the time you are reading a symbol you don't know +how long it is. One traditional method is to read a symbol into a +buffer, realloc()ating the buffer every time you try to read a symbol +that is longer than the buffer. This is beaut, but you still will +want to copy the symbol from the buffer to a more permanent +symbol-table entry say about half the time. + +With obstacks, you can work differently. Use one obstack for all symbol +names. As you read a symbol, grow the name in the obstack gradually. +When the name is complete, finalize it. Then, if the symbol exists already, +free the newly read name. + +The way we do this is to take a large chunk, allocating memory from +low addresses. When you want to build a symbol in the chunk you just +add chars above the current "high water mark" in the chunk. When you +have finished adding chars, because you got to the end of the symbol, +you know how long the chars are, and you can create a new object. +Mostly the chars will not burst over the highest address of the chunk, +because you would typically expect a chunk to be (say) 100 times as +long as an average object. + +In case that isn't clear, when we have enough chars to make up +the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed) +so we just point to it where it lies. No moving of chars is +needed and this is the second win: potentially long strings need +never be explicitly shuffled. Once an object is formed, it does not +change its address during its lifetime. + +When the chars burst over a chunk boundary, we allocate a larger +chunk, and then copy the partly formed object from the end of the old +chunk to the beginning of the new larger chunk. We then carry on +accreting characters to the end of the object as we normally would. + +A special macro is provided to add a single char at a time to a +growing object. This allows the use of register variables, which +break the ordinary 'growth' macro. + +Summary: + We allocate large chunks. + We carve out one object at a time from the current chunk. + Once carved, an object never moves. + We are free to append data of any size to the currently + growing object. + Exactly one object is growing in an obstack at any one time. + You can run one obstack per control block. + You may have as many control blocks as you dare. + Because of the way we do it, you can `unwind' an obstack + back to a previous state.

Sometimes, though, when an old line and a new line are very +similar, it's hard to immediately see the difference. + +You can use "--color-words" to highlight only the changed portions of +lines. However, this can often be hard to read for code, as it loses +the line structure, and you end up with oddly formatted bits. + +Instead, this script post-processes the line-oriented diff, finds pairs +of lines, and highlights the differing segments. It's currently very +simple and stupid about doing these tasks. In particular: + + 1. It will only highlight a pair of lines if they are the only two + lines in a hunk. It could instead try to match up "before" and + "after" lines for a given hunk into pairs of similar lines. + However, this may end up visually distracting, as the paired + lines would have other highlighted lines in between them. And in + practice, the lines which most need attention called to their + small, hard-to-see changes are touching only a single line. + + 2. It will find the common prefix and suffix of two lines, and + consider everything in the middle to be "different". It could + instead do a real diff of the characters between the two lines and + find common subsequences. However, the point of the highlight is to + call attention to a certain area. Even if some small subset of the + highlighted area actually didn't change, that's OK.

-2) Import the head revision from the given Perforce path into a git branch -called "p4" (remotes/p4 actually) - -3) Create a master branch based on it and check it out. - -If you want the entire history (not just the head revision) then you can simply -append a "@all" to the depot path: - - git-p4 clone //depot/project/main@all myproject - - - -If you want more control you can also use the git-p4 sync command directly: - - mkdir repo-git - cd repo-git - git init - git-p4 sync //path/in/your/perforce/depot - -This will import the current head revision of the specified depot path into a -"remotes/p4/master" branch of your git repository. You can use the ---branch=mybranch option to import into a different branch. - -If you want to import the entire history of a given depot path simply use: - - git-p4 sync //path/in/depot@all - - -Note: - -To achieve optimal compression you may want to run 'git repack -a -d -f' after -a big import. This may take a while. - -Incremental Imports -=================== - -After an initial import you can continue to synchronize your git repository -with newer changes from the Perforce depot by just calling - - git-p4 sync - -in your git repository. By default the "remotes/p4/master" branch is updated. - -Advanced Setup -============== - -Suppose you have a periodically updated git repository somewhere, containing a -complete import of a Perforce project. This repository can be cloned and used -with git-p4. When updating the cloned repository with the "sync" command, -git-p4 will try to fetch changes from the original repository first. The git -protocol used with this is usually faster than importing from Perforce -directly. - -This behaviour can be disabled by setting the "git-p4.syncFromOrigin" git -configuration variable to "false". - -Updating -======== - -A common working pattern is to fetch the latest changes from the Perforce depot -and merge them with local uncommitted changes. 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. - -The Perforce changelists will be created with the user who ran git-p4. If you -use --preserve-user then git-p4 will attempt to create Perforce changelists -with the Perforce user corresponding to the git commit author. You need to -have sufficient permissions within Perforce, and the git users need to have -Perforce accounts. Permissions can be granted using 'p4 protect'. - -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. Rebase your latest -# changes against the latest changes in Perforce: - git-p4 rebase -# Submit your locally committed changes back to Perforce - git-p4 submit -# ... and synchronize with Perforce - git-p4 rebase - - -Configuration parameters -======================== - -git-p4.user ($P4USER) - -Allows you to specify the username to use to connect to the Perforce repository. - - git config [--global] git-p4.user public - -git-p4.password ($P4PASS) - -Allows you to specify the password to use to connect to the Perforce repository. -Warning this password will be visible on the command-line invocation of the p4 binary. - - git config [--global] git-p4.password public1234 - -git-p4.port ($P4PORT) - -Specify the port to be used to contact the Perforce server. As this will be passed -directly to the p4 binary, it may be in the format host:port as well. - - git config [--global] git-p4.port codes.zimbra.com:2666 - -git-p4.host ($P4HOST) - -Specify the host to contact for a Perforce repository. - - git config [--global] git-p4.host perforce.example.com - -git-p4.client ($P4CLIENT) - -Specify the client name to use - - git config [--global] git-p4.client public-view - -git-p4.allowSubmit - - git config [--global] git-p4.allowSubmit false - -git-p4.syncFromOrigin - -A useful setup may be that you have a periodically updated git repository -somewhere that contains a complete import of a Perforce project. That git -repository can be used to clone the working repository from and one would -import from Perforce directly after cloning using git-p4. If the connection to -the Perforce server is slow and the working repository hasn't been synced for a -while it may be desirable to fetch changes from the origin git repository using -the efficient git protocol. git-p4 supports this setup by calling "git fetch origin" -by default if there is an origin branch. You can disable this using: - - git config [--global] git-p4.syncFromOrigin false - -git-p4.useclientspec - - git config [--global] git-p4.useclientspec false - -The P4CLIENT environment variable should be correctly set for p4 to be -able to find the relevant client. This client spec will be used to -both filter the files cloned by git and set the directory layout as -specified in the client (this implies --keep-path style semantics). - -git-p4.skipSubmitModTimeCheck - - git config [--global] git-p4.skipSubmitModTimeCheck false - -If true, submit will not check if the p4 change template has been modified. - -git-p4.preserveUser - - git config [--global] git-p4.preserveUser false - -If true, attempt to preserve user names by modifying the p4 changelists. See -the "--preserve-user" submit option. - -git-p4.allowMissingPerforceUsers - - git config [--global] git-p4.allowMissingP4Users false - -If git-p4 is setting the perforce user for a commit (--preserve-user) then -if there is no perforce user corresponding to the git author, git-p4 will -stop. With allowMissingPerforceUsers set to true, git-p4 will use the -current user (i.e. the behavior without --preserve-user) and carry on with -the perforce commit. - -git-p4.skipUserNameCheck - - git config [--global] git-p4.skipUserNameCheck false - -When submitting, git-p4 checks that the git commits are authored by the current -p4 user, and warns if they are not. This disables the check. - -Implementation Details... -========================= - -* Changesets from Perforce are imported using git fast-import. -* The import does not require anything from the Perforce client view as it just uses - "p4 print //depot/path/file#revision" to get the actual file contents. -* Every imported changeset has a special [git-p4...] line at the - end of the log message that gives information about the corresponding - Perforce change number and is also used by git-p4 itself to find out - where to continue importing when doing incremental imports. - Basically when syncing it extracts the perforce change number of the - latest commit in the "p4" branch and uses "p4 changes //depot/path/...@changenum,#head" - to find out which changes need to be imported. -* git-p4 submit uses "git rev-list" to pick the commits between the "p4" branch - and the current branch. - The commits themselves are applied using git diff/format-patch ... | git apply - diff --git a/contrib/git-jump/README b/contrib/git-jump/README new file mode 100644 index 0000000000..1cebc328cb --- /dev/null +++ b/contrib/git-jump/README @@ -0,0 +1,92 @@ +git-jump +======== + +Git-jump is a script for helping you jump to "interesting" parts of your +project in your editor. It works by outputting a set of interesting +spots in the "quickfix" format, which editors like vim can use as a +queue of places to visit (this feature is usually used to jump to errors +produced by a compiler). For example, given a diff like this: + +------------------------------------ +diff --git a/foo.c b/foo.c +index a655540..5a59044 100644 +--- a/foo.c ++++ b/foo.c +@@ -1,3 +1,3 @@ + int main(void) { +- printf("hello word!\n"); ++ printf("hello world!\n"); + } +----------------------------------- + +git-jump will feed this to the editor: + +----------------------------------- +foo.c:2: printf("hello word!\n"); +----------------------------------- + +Obviously this trivial case isn't that interesting; you could just open +`foo.c` yourself. But when you have many changes scattered across a +project, you can use the editor's support to "jump" from point to point. + +Git-jump can generate three types of interesting lists: + + 1. The beginning of any diff hunks. + + 2. The beginning of any merge conflict markers. + + 3. Any grep matches. + + +Using git-jump +-------------- + +To use it, just drop git-jump in your PATH, and then invoke it like +this: + +-------------------------------------------------- +# jump to changes not yet staged for commit +git jump diff + +# jump to changes that are staged for commit; you can give +# arbitrary diff options +git jump diff --cached + +# jump to merge conflicts +git jump merge + +# jump to all instances of foo_bar +git jump grep foo_bar + +# same as above, but case-insensitive; you can give +# arbitrary grep options +git jump grep -i foo_bar +-------------------------------------------------- + + +Related Programs +---------------- + +You can accomplish some of the same things with individual tools. For +example, you can use `git mergetool` to start vimdiff on each unmerged +file. `git jump merge` is for the vim-wielding luddite who just wants to +jump straight to the conflict text with no fanfare. + +As of git v1.7.2, `git grep` knows the `--open-files-in-pager` option, +which does something similar to `git jump grep`. However, it is limited +to positioning the cursor to the correct line in only the first file, +leaving you to locate subsequent hits in that file or other files using +the editor or pager. By contrast, git-jump provides the editor with a +complete list of files and line numbers for each match. + + +Limitations +----------- + +This scripts was written and tested with vim. Given that the quickfix +format is the same as what gcc produces, I expect emacs users have a +similar feature for iterating through the list, but I know nothing about +how to activate it. + +The shell snippets to generate the quickfix lines will almost certainly +choke on filenames with exotic characters (like newlines). diff --git a/contrib/git-jump/git-jump b/contrib/git-jump/git-jump new file mode 100755 index 0000000000..a33674e47a --- /dev/null +++ b/contrib/git-jump/git-jump @@ -0,0 +1,69 @@ +#!/bin/sh + +usage() { + cat <<\EOF +usage: git jump <mode> [<args>] + +Jump to interesting elements in an editor. +The <mode> parameter is one of: + +diff: elements are diff hunks.

By default set to "$GIT_BINDIR/git", which - in turn is by default set to "$(bindir)/git". If you use git from binary - package, set this to "/usr/bin/git". This can just be "git" if your - webserver has a sensible PATH. If you have multiple git versions - installed it can be used to choose which one to use. - * $version - Gitweb version, set automatically when creating gitweb.cgi from - gitweb.perl. You might want to modify it if you are running modified - gitweb. - * $projectroot - Absolute filesystem path which will be prepended to project path; - the path to repository is $projectroot/$project. Set to - $GITWEB_PROJECTROOT during installation. This variable have to be - set correctly for gitweb to find repositories. - * $projects_list - Source of projects list, either directory to scan, or text file - with list of repositories (in the "<URI-encoded repository path> SP - <URI-encoded repository owner>" line format; actually there can be - any sequence of whitespace in place of space (SP)). Set to - $GITWEB_LIST during installation. If empty, $projectroot is used - to scan for repositories. - * $my_url, $my_uri - Full URL and absolute URL of gitweb script; - in earlier versions of gitweb you might have need to set those - variables, now there should be no need to do it. See - $per_request_config if you need to set them still. - * $base_url - Base URL for relative URLs in pages generated by gitweb, - (e.g. $logo, $favicon, @stylesheets if they are relative URLs), - needed and used only for URLs with nonempty PATH_INFO via - <base href="$base_url">. Usually gitweb sets its value correctly, - and there is no need to set this variable, e.g. to $my_uri or "/". - See $per_request_config if you need to set it anyway. - * $home_link - Target of the home link on top of all pages (the first part of view - "breadcrumbs"). By default set to absolute URI of a page ($my_uri). - * @stylesheets - List of URIs of stylesheets (relative to base URI of a page). You - might specify more than one stylesheet, for example use gitweb.css - as base, with site specific modifications in separate stylesheet - to make it easier to upgrade gitweb. You can add 'site' stylesheet - for example by using - push @stylesheets, "gitweb-site.css"; - in the gitweb config file. - * $logo_url, $logo_label - URI and label (title) of GIT logo link (or your site logo, if you choose - to use different logo image). By default they point to git homepage; - in the past they pointed to git documentation at www.kernel.org. - * $projects_list_description_width - The width (in characters) of the projects list "Description" column. - Longer descriptions will be cut (trying to cut at word boundary); - full description is available as 'title' attribute (usually shown on - mouseover). By default set to 25, which might be too small if you - use long project descriptions. - * $projects_list_group_categories - Enables the grouping of projects by category on the project list page. - The category of a project is determined by the $GIT_DIR/category - file or the 'gitweb.category' variable in its repository configuration. - Disabled by default. - * $project_list_default_category - Default category for projects for which none is specified. If set - to the empty string, such projects will remain uncategorized and - listed at the top, above categorized projects. - * @git_base_url_list - List of git base URLs used for URL to where fetch project from, shown - in project summary page. Full URL is "$git_base_url/$project". - You can setup multiple base URLs (for example one for git:// protocol - access, and one for http:// "dumb" protocol access). Note that per - repository configuration in 'cloneurl' file, or as values of gitweb.url - project config. - * $default_blob_plain_mimetype - Default mimetype for blob_plain (raw) view, if mimetype checking - doesn't result in some other type; by default 'text/plain'. - * $default_text_plain_charset - Default charset for text files. If not set, web server configuration - would be used. - * $mimetypes_file - File to use for (filename extension based) guessing of MIME types before - trying /etc/mime.types. Path, if relative, is taken currently as - relative to the current git repository. - * $fallback_encoding - Gitweb assumes this charset if line contains non-UTF-8 characters. - Fallback decoding is used without error checking, so it can be even - 'utf-8'. Value must be valid encoding; see Encoding::Supported(3pm) man - page for a list. By default 'latin1', aka. 'iso-8859-1'. - * @diff_opts - Rename detection options for git-diff and git-diff-tree. By default - ('-M'); set it to ('-C') or ('-C', '-C') to also detect copies, or - set it to () if you don't want to have renames detection. - * $prevent_xss - If true, some gitweb features are disabled to prevent content in - repositories from launching cross-site scripting (XSS) attacks. Set this - to true if you don't trust the content of your repositories. The default - is false. - * $maxload - Used to set the maximum load that we will still respond to gitweb queries. - If server load exceed this value then return "503 Service Unavailable" error. - Server load is taken to be 0 if gitweb cannot determine its value. Set it to - undefined value to turn it off. The default is 300. - * $highlight_bin - Path to the highlight executable to use (must be the one from - http://www.andre-simon.de due to assumptions about parameters and output). - Useful if highlight is not installed on your webserver's PATH. - [Default: highlight] - * $per_request_config - If set to code reference, it would be run once per each request. You can - set parts of configuration that change per session, e.g. by setting it to - sub { $ENV{GL_USER} = $cgi->remote_user || "gitweb"; } - Otherwise it is treated as boolean value: if true gitweb would process - config file once per request, if false it would process config file only - once. Note: $my_url, $my_uri, and $base_url are overwritten with - their default values before every request, so if you want to change - them, be sure to set this variable to true or a code reference effecting - the desired changes. The default is true. - -Projects list file format -~~~~~~~~~~~~~~~~~~~~~~~~~ - -Instead of having gitweb find repositories by scanning filesystem starting -from $projectroot (or $projects_list, if it points to directory), you can -provide list of projects by setting $projects_list to a text file with list -of projects (and some additional info). This file uses the following -format: - -One record (for project / repository) per line, whitespace separated fields; -does not support (at least for now) lines continuation (newline escaping). -Leading and trailing whitespace are ignored, any run of whitespace can be -used as field separator (rules for Perl's "split(' ', $line)"). Keyed by -the first field, which is project name, i.e. path to repository GIT_DIR -relative to $projectroot. Fields use modified URI encoding, defined in -RFC 3986, section 2.1 (Percent-Encoding), or rather "Query string encoding" -(see http://en.wikipedia.org/wiki/Query_string#URL_encoding), the difference -being that SP (' ') can be encoded as '+' (and therefore '+' has to be also -percent-encoded). Reserved characters are: '%' (used for encoding), '+' -(can be used to encode SPACE), all whitespace characters as defined in Perl, -including SP, TAB and LF, (used to separate fields in a record). - -Currently list of fields is - * <repository path> - path to repository GIT_DIR, relative to $projectroot - * <repository owner> - displayed as repository owner, preferably full name, - or email, or both - -You can additionally use $projects_list file to limit which repositories -are visible, and together with $strict_export to limit access to -repositories (see "Gitweb repositories" section in gitweb/INSTALL). - - -Per-repository gitweb configuration -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -You can also configure individual repositories shown in gitweb by creating -file in the GIT_DIR of git repository, or by setting some repo configuration -variable (in GIT_DIR/config). - -You can use the following files in repository: - * README.html - A .html file (HTML fragment) which is included on the gitweb project - summary page inside <div> block element. You can use it for longer - description of a project, to provide links (for example to project's - homepage), etc. This is recognized only if XSS prevention is off - ($prevent_xss is false); a way to include a readme safely when XSS - prevention is on may be worked out in the future. - * description (or gitweb.description) - Short (shortened by default to 25 characters in the projects list page) - single line description of a project (of a repository). Plain text file; - HTML will be escaped. By default set to - Unnamed repository; edit this file to name it for gitweb. - from the template during repository creation. You can use the - gitweb.description repo configuration variable, but the file takes - precedence. - * category (or gitweb.category) - Singe line category of a project, used to group projects if - $projects_list_group_categories is enabled. By default (file and - configuration variable absent), uncategorized projects are put in - the $project_list_default_category category. You can use the - gitweb.category repo configuration variable, but the file takes - precedence. - * cloneurl (or multiple-valued gitweb.url) - File with repository URL (used for clone and fetch), one per line. - Displayed in the project summary page. You can use multiple-valued - gitweb.url repository configuration variable for that, but the file - takes precedence. - * gitweb.owner - You can use the gitweb.owner repository configuration variable to set - repository's owner. It is displayed in the project list and summary - page. If it's not set, filesystem directory's owner is used - (via GECOS field / real name field from getpwiud(3)). - * various gitweb.* config variables (in config) - Read description of %feature hash for detailed list, and some - descriptions. - - -Webserver configuration ------------------------ - -If you want to have one URL for both gitweb and your http:// -repositories, you can configure apache like this: - -<VirtualHost *:80> - ServerName git.example.org - DocumentRoot /pub/git - SetEnv GITWEB_CONFIG /etc/gitweb.conf - - # turning on mod rewrite - RewriteEngine on - - # make the front page an internal rewrite to the gitweb script - RewriteRule ^/$ /cgi-bin/gitweb.cgi - - # make access for "dumb clients" work - RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ /cgi-bin/gitweb.cgi%{REQUEST_URI} [L,PT] -</VirtualHost> - -The above configuration expects your public repositories to live under -/pub/git and will serve them as http://git.domain.org/dir-under-pub-git, -both as cloneable GIT URL and as browseable gitweb interface. -If you then start your git-daemon with --base-path=/pub/git --export-all -then you can even use the git:// URL with exactly the same path. - -Setting the environment variable GITWEB_CONFIG will tell gitweb to use -the named file (i.e. in this example /etc/gitweb.conf) as a -configuration for gitweb.

Plumbing strings should not be translated, since + they're part of Git's API. + + - Adjust the strings so that they're easy to translate. Most of the + advice in `info '(gettext)Preparing Strings'` applies here. + + - If something is unclear or ambiguous you can use a "TRANSLATORS" + comment to tell the translators what to make of it. These will be + extracted by xgettext(1) and put in the po/*.po files, e.g. from + git-am.sh: + + # TRANSLATORS: Make sure to include [y], [n], [e], [v] and [a] + # in your translation. The program will only accept English + # input at this point. + gettext "Apply? [y]es/[n]o/[e]dit/[v]iew patch/[a]ccept all " + + Or in C, from builtin/revert.c: + + /* TRANSLATORS: %s will be "revert" or "cherry-pick" */ + die(_("%s: Unable to write new index file"), action_name(opts)); + +We provide wrappers for C, Shell and Perl programs. Here's how they're +used: + +C: + + - Include builtin.h at the top, it'll pull in in gettext.h, which + defines the gettext interface. Consult with the list if you need to + use gettext.h directly. + + - The C interface is a subset of the normal GNU gettext + interface. We currently export these functions: + + - _() + + Mark and translate a string. E.g.: + + printf(_("HEAD is now at %s"), hex); + + - Q_() + + Mark and translate a plural string. E.g.: + + printf(Q_("%d commit", "%d commits", number_of_commits)); + + This is just a wrapper for the ngettext() function. + + - N_() + + A no-op pass-through macro for marking strings inside static + initializations, e.g.: + + static const char *reset_type_names[] = { + N_("mixed"), N_("soft"), N_("hard"), N_("merge"), N_("keep"), NULL + }; + + And then, later: + + die(_("%s reset is not allowed in a bare repository"), + _(reset_type_names[reset_type])); + + Here _() couldn't have statically determined what the translation + string will be, but since it was already marked for translation + with N_() the look-up in the message catalog will succeed. + +Shell: + + - The Git gettext shell interface is just a wrapper for + gettext.sh. Import it right after git-sh-setup like this: + + . git-sh-setup + . git-sh-i18n + + And then use the gettext or eval_gettext functions: + + # For constant interface messages: + gettext "A message for the user"; echo + + # To interpolate variables: + details="oh noes" + eval_gettext "An error occured: \$details"; echo + + In addition we have wrappers for messages that end with a trailing + newline. I.e. you could write the above as: + + # For constant interface messages: + gettextln "A message for the user" + + # To interpolate variables: + details="oh noes" + eval_gettextln "An error occured: \$details" + + More documentation about the interface is available in the GNU info + page: `info '(gettext)sh'`. Looking at git-am.sh (the first shell + command to be translated) for examples is also useful: + + git log --reverse -p --grep=i18n git-am.sh + +Perl: + + - The Git::I18N module provides a limited subset of the + Locale::Messages functionality, e.g.: + + use Git::I18N; + print __("Welcome to Git!\n"); + printf __("The following error occured: %s\n"), $error; + + Run `perldoc perl/Git/I18N.pm` for more info. + + +Testing marked strings +---------------------- + +Even if you've correctly marked porcelain strings for translation +something in the test suite might still depend on the US English +version of the strings, e.g. to grep some error message or other +output. + +To smoke out issues like these Git can be compiled with gettext poison +support, at the top-level: + + make GETTEXT_POISON=YesPlease + +That'll give you a git which emits gibberish on every call to +gettext. It's obviously not meant to be installed, but you should run +the test suite with it: + + cd t && prove -j 9 ./t[0-9]*.sh + +If tests break with it you should inspect them manually and see if +what you're translating is sane, i.e. that you're not translating +plumbing output. + +If not you should replace calls to grep with test_i18ngrep, or +test_cmp calls with test_i18ncmp. If that's not enough you can skip +the whole test by making it depend on the C_LOCALE_OUTPUT +prerequisite.
