It includes a Python module called ``git_multimail.py``, -which can either be used as a hook script directly or can be imported -as a Python module into another script. - -git-multimail is derived from the Git project's old -contrib/hooks/post-receive-email, and is mostly compatible with that -script. See README.migrate-from-post-receive-email for details about -the differences and for how to migrate from post-receive-email to -git-multimail. - -git-multimail, like the rest of the Git project, is licensed under -GPLv2 (see the COPYING file for details). - -Please note: although, as a convenience, git-multimail may be -distributed along with the main Git project, development of -git-multimail takes place in its own, separate project. See section -"Getting involved" below for more information. - - -By default, for each push received by the repository, git-multimail: - -1. Outputs one email summarizing each reference that was changed. - These "reference change" (called "refchange" below) emails describe - the nature of the change (e.g., was the reference created, deleted, - fast-forwarded, etc.) and include a one-line summary of each commit - that was added to the reference. - -2. Outputs one email for each new commit that was introduced by the - reference change. These "commit" emails include a list of the - files changed by the commit, followed by the diffs of files - modified by the commit. The commit emails are threaded to the - corresponding reference change email via "In-Reply-To". This style - (similar to the "git format-patch" style used on the Git mailing - list) makes it easy to scan through the emails, jump to patches - that need further attention, and write comments about specific - commits. Commits are handled in reverse topological order (i.e., - parents shown before children). For example:: - - [git] branch master updated - + [git] 01/08: doc: fix xref link from api docs to manual pages - + [git] 02/08: api-credentials.txt: show the big picture first - + [git] 03/08: api-credentials.txt: mention credential.helper explicitly - + [git] 04/08: api-credentials.txt: add "see also" section - + [git] 05/08: t3510 (cherry-pick-sequence): add missing '&&' - + [git] 06/08: Merge branch 'rr/maint-t3510-cascade-fix' - + [git] 07/08: Merge branch 'mm/api-credentials-doc' - + [git] 08/08: Git 1.7.11-rc2 - - By default, each commit appears in exactly one commit email, the - first time that it is pushed to the repository. If a commit is later - merged into another branch, then a one-line summary of the commit - is included in the reference change email (as usual), but no - additional commit email is generated. See - `multimailhook.refFilter(Inclusion|Exclusion|DoSend|DontSend)Regex` - below to configure which branches and tags are watched by the hook. - - By default, reference change emails have their "Reply-To" field set - to the person who pushed the change, and commit emails have their - "Reply-To" field set to the author of the commit. - -3. Output one "announce" mail for each new annotated tag, including - information about the tag and optionally a shortlog describing the - changes since the previous tag. Such emails might be useful if you - use annotated tags to mark releases of your project. - - -Requirements ------------- - -* Python 2.x, version 2.4 or later. No non-standard Python modules - are required. git-multimail has preliminary support for Python 3 - (but it has been better tested with Python 2). - -* The ``git`` command must be in your PATH. git-multimail is known to - work with Git versions back to 1.7.1. (Earlier versions have not - been tested; if you do so, please report your results.) - -* To send emails using the default configuration, a standard sendmail - program must be located at '/usr/sbin/sendmail' or - '/usr/lib/sendmail' and must be configured correctly to send emails. - If this is not the case, set multimailhook.sendmailCommand, or see - the multimailhook.mailer configuration variable below for how to - configure git-multimail to send emails via an SMTP server. - - -Invocation ----------- - -``git_multimail.py`` is designed to be used as a ``post-receive`` hook in a -Git repository (see githooks(5)). Link or copy it to -$GIT_DIR/hooks/post-receive within the repository for which email -notifications are desired. Usually it should be installed on the -central repository for a project, to which all commits are eventually -pushed. - -For use on pre-v1.5.1 Git servers, ``git_multimail.py`` can also work as -an ``update`` hook, taking its arguments on the command line. To use -this script in this manner, link or copy it to $GIT_DIR/hooks/update. -Please note that the script is not completely reliable in this mode -[1]_. - -Alternatively, ``git_multimail.py`` can be imported as a Python module -into your own Python post-receive script. This method is a bit more -work, but allows the behavior of the hook to be customized using -arbitrary Python code. For example, you can use a custom environment -(perhaps inheriting from GenericEnvironment or GitoliteEnvironment) to - -* change how the user who did the push is determined - -* read users' email addresses from an LDAP server or from a database - -* decide which users should be notified about which commits based on - the contents of the commits (e.g., for users who want to be notified - only about changes affecting particular files or subdirectories) - -Or you can change how emails are sent by writing your own Mailer -class. The ``post-receive`` script in this directory demonstrates how -to use ``git_multimail.py`` as a Python module. (If you make interesting -changes of this type, please consider sharing them with the -community.) - - -Troubleshooting/FAQ -------------------- - -Please read ``__ for frequently asked -questions and common issues with git-multimail. - - -Configuration -------------- - -By default, git-multimail mostly takes its configuration from the -following ``git config`` settings: - -multimailhook.environment - This describes the general environment of the repository. In most - cases, you do not need to specify a value for this variable: - `git-multimail` will autodetect which environment to use. - Currently supported values: - - generic - the username of the pusher is read from $USER or $USERNAME and - the repository name is derived from the repository's path. - - gitolite - Environment to use when ``git-multimail`` is ran as a gitolite_ - hook. - - The username of the pusher is read from $GL_USER, the repository - name is read from $GL_REPO, and the From: header value is - optionally read from gitolite.conf (see multimailhook.from). - - For more information about gitolite and git-multimail, read - ``__ - - stash - Environment to use when ``git-multimail`` is ran as an Atlassian - BitBucket Server (formerly known as Atlassian Stash) hook. - - **Warning:** this mode was provided by a third-party contributor - and never tested by the git-multimail maintainers. It is - provided as-is and may or may not work for you. - - This value is automatically assumed when the stash-specific - flags (``--stash-user`` and ``--stash-repo``) are specified on - the command line. When this environment is active, the username - and repo come from these two command line flags, which must be - specified. - - gerrit - Environment to use when ``git-multimail`` is ran as a - ``ref-updated`` Gerrit hook. - - This value is used when the gerrit-specific command line flags - (``--oldrev``, ``--newrev``, ``--refname``, ``--project``) for - gerrit's ref-updated hook are present. When this environment is - active, the username of the pusher is taken from the - ``--submitter`` argument if that command line option is passed, - otherwise 'Gerrit' is used. The repository name is taken from - the ``--project`` option on the command line, which must be passed. - - For more information about gerrit and git-multimail, read - ``__ - - If none of these environments is suitable for your setup, then you - can implement a Python class that inherits from Environment and - instantiate it via a script that looks like the example - post-receive script. - - The environment value can be specified on the command line using - the ``--environment`` option. If it is not specified on the - command line or by ``multimailhook.environment``, the value is - guessed as follows: - - * If stash-specific (respectively gerrit-specific) command flags - are present on the command-line, then ``stash`` (respectively - ``gerrit``) is used. - - * If the environment variables $GL_USER and $GL_REPO are set, then - ``gitolite`` is used. - - * If none of the above apply, then ``generic`` is used. - -multimailhook.repoName - A short name of this Git repository, to be used in various places - in the notification email text. The default is to use $GL_REPO - for gitolite repositories, or otherwise to derive this value from - the repository path name. - -multimailhook.mailingList - The list of email addresses to which notification emails should be - sent, as RFC 2822 email addresses separated by commas. This - configuration option can be multivalued. Leave it unset or set it - to the empty string to not send emails by default. The next few - settings can be used to configure specific address lists for - specific types of notification email. - -multimailhook.refchangeList - The list of email addresses to which summary emails about - reference changes should be sent, as RFC 2822 email addresses - separated by commas. This configuration option can be - multivalued. The default is the value in - multimailhook.mailingList. Set this value to "none" (or the empty - string) to prevent reference change emails from being sent even if - multimailhook.mailingList is set. - -multimailhook.announceList - The list of email addresses to which emails about new annotated - tags should be sent, as RFC 2822 email addresses separated by - commas. This configuration option can be multivalued. The - default is the value in multimailhook.refchangeList or - multimailhook.mailingList. Set this value to "none" (or the empty - string) to prevent annotated tag announcement emails from being sent - even if one of the other values is set. - -multimailhook.commitList - The list of email addresses to which emails about individual new - commits should be sent, as RFC 2822 email addresses separated by - commas. This configuration option can be multivalued. The - default is the value in multimailhook.mailingList. Set this value - to "none" (or the empty string) to prevent notification emails about - individual commits from being sent even if - multimailhook.mailingList is set. - -multimailhook.announceShortlog - If this option is set to true, then emails about changes to - annotated tags include a shortlog of changes since the previous - tag. This can be useful if the annotated tags represent releases; - then the shortlog will be a kind of rough summary of what has - happened since the last release. But if your tagging policy is - not so straightforward, then the shortlog might be confusing - rather than useful. Default is false. - -multimailhook.commitEmailFormat - The format of email messages for the individual commits, can be "text" or - "html". In the latter case, the emails will include diffs using colorized - HTML instead of plain text used by default. Note that this currently the - ref change emails are always sent in plain text. - - Note that when using "html", the formatting is done by parsing the - output of ``git log`` with ``-p``. When using - ``multimailhook.commitLogOpts`` to specify a ``--format`` for - ``git log``, one may get false positive (e.g. lines in the body of - the message starting with ``+++`` or ``---`` colored in red or - green). - - By default, all the message is HTML-escaped. See - ``multimailhook.htmlInIntro`` to change this behavior. - -multimailhook.commitBrowseURL - Used to generate a link to an online repository browser in commit - emails. This variable must be a string. Format directives like - ``%()s`` will be expanded the same way as template - strings. In particular, ``%(id)s`` will be replaced by the full - Git commit identifier (40-chars hexadecimal). - - If the string does not contain any format directive, then - ``%(id)s`` will be automatically added to the string. If you don't - want ``%(id)s`` to be automatically added, use the empty format - directive ``%()s`` anywhere in the string. - - For example, a suitable value for the git-multimail project itself - would be - ``https://github.com/git-multimail/git-multimail/commit/%(id)s``. - -multimailhook.htmlInIntro, multimailhook.htmlInFooter - When generating an HTML message, git-multimail escapes any HTML - sequence by default. This means that if a template contains HTML - like ``link``, the reader will see the HTML - source code and not a proper link. - - Set ``multimailhook.htmlInIntro`` to true to allow writing HTML - formatting in introduction templates. Similarly, set - ``multimailhook.htmlInFooter`` for HTML in the footer. - - Variables expanded in the template are still escaped. For example, - if a repository's path contains a ``<``, it will be rendered as - such in the message. - - Read ``__ for more details and - examples. - -multimailhook.refchangeShowGraph - If this option is set to true, then summary emails about reference - changes will additionally include: - - * a graph of the added commits (if any) - - * a graph of the discarded commits (if any) - - The log is generated by running ``git log --graph`` with the options - specified in graphOpts. The default is false. - -multimailhook.refchangeShowLog - If this option is set to true, then summary emails about reference - changes will include a detailed log of the added commits in - addition to the one line summary. The log is generated by running - ``git log`` with the options specified in multimailhook.logOpts. - Default is false. - -multimailhook.mailer - This option changes the way emails are sent. Accepted values are: - - * **sendmail (the default)**: use the command ``/usr/sbin/sendmail`` or - ``/usr/lib/sendmail`` (or sendmailCommand, if configured). This - mode can be further customized via the following options: - - multimailhook.sendmailCommand - The command used by mailer ``sendmail`` to send emails. Shell - quoting is allowed in the value of this setting, but remember that - Git requires double-quotes to be escaped; e.g.:: - - git config multimailhook.sendmailcommand '/usr/sbin/sendmail -oi -t -F \"Git Repo\"' - - Default is '/usr/sbin/sendmail -oi -t' or - '/usr/lib/sendmail -oi -t' (depending on which file is - present and executable). - - multimailhook.envelopeSender - If set then pass this value to sendmail via the -f option to set - the envelope sender address. - - * **smtp**: use Python's smtplib. This is useful when the sendmail - command is not available on the system. This mode can be - further customized via the following options: - - multimailhook.smtpServer - The name of the SMTP server to connect to. The value can - also include a colon and a port number; e.g., - ``mail.example.com:25``. Default is 'localhost' using port 25. - - multimailhook.smtpUser, multimailhook.smtpPass - Server username and password. Required if smtpEncryption is 'ssl'. - Note that the username and password currently need to be - set cleartext in the configuration file, which is not - recommended. If you need to use this option, be sure your - configuration file is read-only. - - multimailhook.envelopeSender - The sender address to be passed to the SMTP server. If - unset, then the value of multimailhook.from is used. - - multimailhook.smtpServerTimeout - Timeout in seconds. - - multimailhook.smtpEncryption - Set the security type. Allowed values: ``none``, ``ssl``, ``tls`` (starttls). - Default is ``none``. - - multimailhook.smtpCACerts - Set the path to a list of trusted CA certificate to verify the - server certificate, only supported when ``smtpEncryption`` is - ``tls``. If unset or empty, the server certificate is not - verified. If it targets a file containing a list of trusted CA - certificates (PEM format) these CAs will be used to verify the - server certificate. For debian, you can set - ``/etc/ssl/certs/ca-certificates.crt`` for using the system - trusted CAs. For self-signed server, you can add your server - certificate to the system store:: - - cd /usr/local/share/ca-certificates/ - openssl s_client -starttls smtp \ - -connect mail.example.net:587 -showcerts \ - /dev/null \ - | openssl x509 -outform PEM >mail.example.net.crt - update-ca-certificates - - and used the updated ``/etc/ssl/certs/ca-certificates.crt``. Or - directly use your ``/path/to/mail.example.net.crt``. Default is - unset. - - multimailhook.smtpServerDebugLevel - Integer number. Set to greater than 0 to activate debugging. - -multimailhook.from, multimailhook.fromCommit, multimailhook.fromRefchange - If set, use this value in the From: field of generated emails. - ``fromCommit`` is used for commit emails, ``fromRefchange`` is - used for refchange emails, and ``from`` is used as fall-back in - all cases. - - The value for these variables can be either: - - - An email address, which will be used directly. - - - The value ``pusher``, in which case the pusher's address (if - available) will be used. - - - The value ``author`` (meaningful only for ``fromCommit``), in which - case the commit author's address will be used. - - If config values are unset, the value of the From: header is - determined as follows: - - 1. (gitolite environment only) Parse gitolite.conf, looking for a - block of comments that looks like this:: - - # BEGIN USER EMAILS - # username Firstname Lastname - # END USER EMAILS - - If that block exists, and there is a line between the BEGIN - USER EMAILS and END USER EMAILS lines where the first field - matches the gitolite username ($GL_USER), use the rest of the - line for the From: header. - - 2. If the user.email configuration setting is set, use its value - (and the value of user.name, if set). - - 3. Use the value of multimailhook.envelopeSender. - -multimailhook.administrator - The name and/or email address of the administrator of the Git - repository; used in FOOTER_TEMPLATE. Default is - multimailhook.envelopesender if it is set; otherwise a generic - string is used. - -multimailhook.emailPrefix - All emails have this string prepended to their subjects, to aid - email filtering (though filtering based on the X-Git-* email - headers is probably more robust). Default is the short name of - the repository in square brackets; e.g., ``[myrepo]``. Set this - value to the empty string to suppress the email prefix. You may - use the placeholder ``%(repo_shortname)s`` for the short name of - the repository. - -multimailhook.emailMaxLines - The maximum number of lines that should be included in the body of - a generated email. If not specified, there is no limit. Lines - beyond the limit are suppressed and counted, and a final line is - added indicating the number of suppressed lines. - -multimailhook.emailMaxLineLength - The maximum length of a line in the email body. Lines longer than - this limit are truncated to this length with a trailing ``[...]`` - added to indicate the missing text. The default is 500, because - (a) diffs with longer lines are probably from binary files, for - which a diff is useless, and (b) even if a text file has such long - lines, the diffs are probably unreadable anyway. To disable line - truncation, set this option to 0. - -multimailhook.subjectMaxLength - The maximum length of the subject line (i.e. the ``oneline`` field - in templates, not including the prefix). Lines longer than this - limit are truncated to this length with a trailing ``[...]`` added - to indicate the missing text. This option The default is to use - ``multimailhook.emailMaxLineLength``. This option avoids sending - emails with overly long subject lines, but should not be needed if - the commit messages follow the Git convention (one short subject - line, then a blank line, then the message body). To disable line - truncation, set this option to 0. - -multimailhook.maxCommitEmails - The maximum number of commit emails to send for a given change. - When the number of patches is larger that this value, only the - summary refchange email is sent. This can avoid accidental - mailbombing, for example on an initial push. To disable commit - emails limit, set this option to 0. The default is 500. - -multimailhook.emailStrictUTF8 - If this boolean option is set to `true`, then the main part of the - email body is forced to be valid UTF-8. Any characters that are - not valid UTF-8 are converted to the Unicode replacement - character, U+FFFD. The default is `true`. - - This option is ineffective with Python 3, where non-UTF-8 - characters are unconditionally replaced. - -multimailhook.diffOpts - Options passed to ``git diff-tree`` when generating the summary - information for ReferenceChange emails. Default is ``--stat - --summary --find-copies-harder``. Add -p to those options to - include a unified diff of changes in addition to the usual summary - output. Shell quoting is allowed; see ``multimailhook.logOpts`` for - details. - -multimailhook.graphOpts - Options passed to ``git log --graph`` when generating graphs for the - reference change summary emails (used only if refchangeShowGraph - is true). The default is '--oneline --decorate'. - - Shell quoting is allowed; see logOpts for details. - -multimailhook.logOpts - Options passed to ``git log`` to generate additional info for - reference change emails (used only if refchangeShowLog is set). - For example, adding -p will show each commit's complete diff. The - default is empty. - - Shell quoting is allowed; for example, a log format that contains - spaces can be specified using something like:: - - git config multimailhook.logopts '--pretty=format:"%h %aN <%aE>%n%s%n%n%b%n"' - - If you want to set this by editing your configuration file - directly, remember that Git requires double-quotes to be escaped - (see git-config(1) for more information):: - - [multimailhook] - logopts = --pretty=format:\"%h %aN <%aE>%n%s%n%n%b%n\" - -multimailhook.commitLogOpts - Options passed to ``git log`` to generate additional info for - revision change emails. For example, adding --ignore-all-spaces - will suppress whitespace changes. The default options are ``-C - --stat -p --cc``. Shell quoting is allowed; see - multimailhook.logOpts for details. - -multimailhook.dateSubstitute - String to use as a substitute for ``Date:`` in the output of ``git - log`` while formatting commit messages. This is useful to avoid - emitting a line that can be interpreted by mailers as the start of - a cited message (Zimbra webmail in particular). Defaults to - ``CommitDate:``. Set to an empty string or ``none`` to deactivate - the behavior. - -multimailhook.emailDomain - Domain name appended to the username of the person doing the push - to convert it into an email address - (via ``"%s@%s" % (username, emaildomain)``). More complicated - schemes can be implemented by overriding Environment and - overriding its get_pusher_email() method. - -multimailhook.replyTo, multimailhook.replyToCommit, multimailhook.replyToRefchange - Addresses to use in the Reply-To: field for commit emails - (replyToCommit) and refchange emails (replyToRefchange). - multimailhook.replyTo is used as default when replyToCommit or - replyToRefchange is not set. The shortcuts ``pusher`` and - ``author`` are allowed with the same semantics as for - ``multimailhook.from``. In addition, the value ``none`` can be - used to omit the ``Reply-To:`` field. - - The default is ``pusher`` for refchange emails, and ``author`` for - commit emails. - -multimailhook.quiet - Do not output the list of email recipients from the hook - -multimailhook.stdout - For debugging, send emails to stdout rather than to the - mailer. Equivalent to the --stdout command line option - -multimailhook.scanCommitForCc - If this option is set to true, than recipients from lines in commit body - that starts with ``CC:`` will be added to CC list. - Default: false - -multimailhook.combineWhenSingleCommit - If this option is set to true and a single new commit is pushed to - a branch, combine the summary and commit email messages into a - single email. - Default: true - -multimailhook.refFilterInclusionRegex, multimailhook.refFilterExclusionRegex, multimailhook.refFilterDoSendRegex, multimailhook.refFilterDontSendRegex - **Warning:** these options are experimental. They should work, but - the user-interface is not stable yet (in particular, the option - names may change). If you want to participate in stabilizing the - feature, please contact the maintainers and/or send pull-requests. - If you are happy with the current shape of the feature, please - report it too. - - Regular expressions that can be used to limit refs for which email - updates will be sent. It is an error to specify both an inclusion - and an exclusion regex. If a ``refFilterInclusionRegex`` is - specified, emails will only be sent for refs which match this - regex. If a ``refFilterExclusionRegex`` regex is specified, - emails will be sent for all refs except those that match this - regex (or that match a predefined regex specific to the - environment, such as "^refs/notes" for most environments and - "^refs/notes|^refs/changes" for the gerrit environment). - - The expressions are matched against the complete refname, and is - considered to match if any substring matches. For example, to - filter-out all tags, set ``refFilterExclusionRegex`` to - ``^refs/tags/`` (note the leading ``^`` but no trailing ``$``). If - you set ``refFilterExclusionRegex`` to ``master``, then any ref - containing ``master`` will be excluded (the ``master`` branch, but - also ``refs/tags/master`` or ``refs/heads/foo-master-bar``). - - ``refFilterDoSendRegex`` and ``refFilterDontSendRegex`` are - analogous to ``refFilterInclusionRegex`` and - ``refFilterExclusionRegex`` with one difference: with - ``refFilterDoSendRegex`` and ``refFilterDontSendRegex``, commits - introduced by one excluded ref will not be considered as new when - they reach an included ref. Typically, if you add a branch ``foo`` - to ``refFilterDontSendRegex``, push commits to this branch, and - later merge branch ``foo`` into ``master``, then the notification - email for ``master`` will contain a commit email only for the - merge commit. If you include ``foo`` in - ``refFilterExclusionRegex``, then at the time of merge, you will - receive one commit email per commit in the branch. - - These variables can be multi-valued, like:: - - [multimailhook] - refFilterExclusionRegex = ^refs/tags/ - refFilterExclusionRegex = ^refs/heads/master$ - - You can also provide a whitespace-separated list like:: - - [multimailhook] - refFilterExclusionRegex = ^refs/tags/ ^refs/heads/master$ - - Both examples exclude tags and the master branch, and are - equivalent to:: - - [multimailhook] - refFilterExclusionRegex = ^refs/tags/|^refs/heads/master$ - - ``refFilterInclusionRegex`` and ``refFilterExclusionRegex`` are - strictly stronger than ``refFilterDoSendRegex`` and - ``refFilterDontSendRegex``. In other words, adding a ref to a - DoSend/DontSend regex has no effect if it is already excluded by a - Exclusion/Inclusion regex. - -multimailhook.logFile, multimailhook.errorLogFile, multimailhook.debugLogFile - - When set, these variable designate path to files where - git-multimail will log some messages. Normal messages and error - messages are sent to ``logFile``, and error messages are also sent - to ``errorLogFile``. Debug messages and all other messages are - sent to ``debugLogFile``. The recommended way is to set only one - of these variables, but it is also possible to set several of them - (part of the information is then duplicated in several log files, - for example errors are duplicated to all log files). - - Relative path are relative to the Git repository where the push is - done. - -multimailhook.verbose - - Verbosity level of git-multimail on its standard output. By - default, show only error and info messages. If set to true, show - also debug messages. - -Email filtering aids --------------------- - -All emails include extra headers to enable fine tuned filtering and -give information for debugging. All emails include the headers -``X-Git-Host``, ``X-Git-Repo``, ``X-Git-Refname``, and ``X-Git-Reftype``. -ReferenceChange emails also include headers ``X-Git-Oldrev`` and ``X-Git-Newrev``; -Revision emails also include header ``X-Git-Rev``. - - -Customizing email contents --------------------------- - -git-multimail mostly generates emails by expanding templates. The -templates can be customized. To avoid the need to edit -``git_multimail.py`` directly, the preferred way to change the templates -is to write a separate Python script that imports ``git_multimail.py`` as -a module, then replaces the templates in place. See the provided -post-receive script for an example of how this is done. - - -Customizing git-multimail for your environment ----------------------------------------------- - -git-multimail is mostly customized via an "environment" that describes -the local environment in which Git is running. Two types of -environment are built in: - -GenericEnvironment - a stand-alone Git repository. - -GitoliteEnvironment - a Git repository that is managed by gitolite_. For such - repositories, the identity of the pusher is read from - environment variable $GL_USER, the name of the repository is read - from $GL_REPO (if it is not overridden by multimailhook.reponame), - and the From: header value is optionally read from gitolite.conf - (see multimailhook.from). - -By default, git-multimail assumes GitoliteEnvironment if $GL_USER and -$GL_REPO are set, and otherwise assumes GenericEnvironment. -Alternatively, you can choose one of these two environments explicitly -by setting a ``multimailhook.environment`` config setting (which can -have the value `generic` or `gitolite`) or by passing an --environment -option to the script. - -If you need to customize the script in ways that are not supported by -the existing environments, you can define your own environment class -class using arbitrary Python code. To do so, you need to import -``git_multimail.py`` as a Python module, as demonstrated by the example -post-receive script. Then implement your environment class; it should -usually inherit from one of the existing Environment classes and -possibly one or more of the EnvironmentMixin classes. Then set the -``environment`` variable to an instance of your own environment class -and pass it to ``run_as_post_receive_hook()``. - -The standard environment classes, GenericEnvironment and -GitoliteEnvironment, are in fact themselves put together out of a -number of mixin classes, each of which handles one aspect of the -customization. For the finest control over your configuration, you -can specify exactly which mixin classes your own environment class -should inherit from, and override individual methods (or even add your -own mixin classes) to implement entirely new behaviors. If you -implement any mixins that might be useful to other people, please -consider sharing them with the community! - - -Getting involved ----------------- - -Please, read ``__ for instructions on how to -contribute to git-multimail. - - -Footnotes ---------- - -.. [1] Because of the way information is passed to update hooks, the - script's method of determining whether a commit has already - been seen does not work when it is used as an ``update`` script. - In particular, no notification email will be generated for a - new commit that is added to multiple references in the same - push.

It includes a Python module called ``git_multimail.py``, +which can either be used as a hook script directly or can be imported +as a Python module into another script. + +git-multimail is derived from the Git project's old +contrib/hooks/post-receive-email, and is mostly compatible with that +script. See README.migrate-from-post-receive-email for details about +the differences and for how to migrate from post-receive-email to +git-multimail. + +git-multimail, like the rest of the Git project, is licensed under +GPLv2 (see the COPYING file for details). + +Please note: although, as a convenience, git-multimail may be +distributed along with the main Git project, development of +git-multimail takes place in its own, separate project. Please, read +``__ for more information. + + +By default, for each push received by the repository, git-multimail: + +1. Outputs one email summarizing each reference that was changed. + These "reference change" (called "refchange" below) emails describe + the nature of the change (e.g., was the reference created, deleted, + fast-forwarded, etc.) and include a one-line summary of each commit + that was added to the reference. + +2. Outputs one email for each new commit that was introduced by the + reference change. These "commit" emails include a list of the + files changed by the commit, followed by the diffs of files + modified by the commit. The commit emails are threaded to the + corresponding reference change email via "In-Reply-To". This style + (similar to the "git format-patch" style used on the Git mailing + list) makes it easy to scan through the emails, jump to patches + that need further attention, and write comments about specific + commits. Commits are handled in reverse topological order (i.e., + parents shown before children). For example:: + + [git] branch master updated + + [git] 01/08: doc: fix xref link from api docs to manual pages + + [git] 02/08: api-credentials.txt: show the big picture first + + [git] 03/08: api-credentials.txt: mention credential.helper explicitly + + [git] 04/08: api-credentials.txt: add "see also" section + + [git] 05/08: t3510 (cherry-pick-sequence): add missing '&&' + + [git] 06/08: Merge branch 'rr/maint-t3510-cascade-fix' + + [git] 07/08: Merge branch 'mm/api-credentials-doc' + + [git] 08/08: Git 1.7.11-rc2 + + By default, each commit appears in exactly one commit email, the + first time that it is pushed to the repository. If a commit is later + merged into another branch, then a one-line summary of the commit + is included in the reference change email (as usual), but no + additional commit email is generated. See + `multimailhook.refFilter(Inclusion|Exclusion|DoSend|DontSend)Regex` + below to configure which branches and tags are watched by the hook. + + By default, reference change emails have their "Reply-To" field set + to the person who pushed the change, and commit emails have their + "Reply-To" field set to the author of the commit. + +3. Output one "announce" mail for each new annotated tag, including + information about the tag and optionally a shortlog describing the + changes since the previous tag. Such emails might be useful if you + use annotated tags to mark releases of your project. + + +Requirements +------------ + +* Python 2.x, version 2.4 or later. No non-standard Python modules + are required. git-multimail has preliminary support for Python 3 + (but it has been better tested with Python 2). + +* The ``git`` command must be in your PATH. git-multimail is known to + work with Git versions back to 1.7.1. (Earlier versions have not + been tested; if you do so, please report your results.) + +* To send emails using the default configuration, a standard sendmail + program must be located at '/usr/sbin/sendmail' or + '/usr/lib/sendmail' and must be configured correctly to send emails. + If this is not the case, set multimailhook.sendmailCommand, or see + the multimailhook.mailer configuration variable below for how to + configure git-multimail to send emails via an SMTP server. + +* git-multimail is currently tested only on Linux. It may or may not + work on other platforms such as Windows and Mac OS. See + ``__ to improve the situation. + + +Invocation +---------- + +``git_multimail.py`` is designed to be used as a ``post-receive`` hook in a +Git repository (see githooks(5)). Link or copy it to +$GIT_DIR/hooks/post-receive within the repository for which email +notifications are desired. Usually it should be installed on the +central repository for a project, to which all commits are eventually +pushed. + +For use on pre-v1.5.1 Git servers, ``git_multimail.py`` can also work as +an ``update`` hook, taking its arguments on the command line. To use +this script in this manner, link or copy it to $GIT_DIR/hooks/update. +Please note that the script is not completely reliable in this mode +[1]_. + +Alternatively, ``git_multimail.py`` can be imported as a Python module +into your own Python post-receive script. This method is a bit more +work, but allows the behavior of the hook to be customized using +arbitrary Python code. For example, you can use a custom environment +(perhaps inheriting from GenericEnvironment or GitoliteEnvironment) to + +* change how the user who did the push is determined + +* read users' email addresses from an LDAP server or from a database + +* decide which users should be notified about which commits based on + the contents of the commits (e.g., for users who want to be notified + only about changes affecting particular files or subdirectories) + +Or you can change how emails are sent by writing your own Mailer +class. The ``post-receive`` script in this directory demonstrates how +to use ``git_multimail.py`` as a Python module. (If you make interesting +changes of this type, please consider sharing them with the +community.) + + +Troubleshooting/FAQ +------------------- + +Please read ``__ for frequently asked +questions and common issues with git-multimail. + + +Configuration +------------- + +By default, git-multimail mostly takes its configuration from the +following ``git config`` settings: + +multimailhook.environment + This describes the general environment of the repository. In most + cases, you do not need to specify a value for this variable: + `git-multimail` will autodetect which environment to use. + Currently supported values: + + generic + the username of the pusher is read from $USER or $USERNAME and + the repository name is derived from the repository's path. + + gitolite + Environment to use when ``git-multimail`` is ran as a gitolite_ + hook. + + The username of the pusher is read from $GL_USER, the repository + name is read from $GL_REPO, and the From: header value is + optionally read from gitolite.conf (see multimailhook.from). + + For more information about gitolite and git-multimail, read + ``__ + + stash + Environment to use when ``git-multimail`` is ran as an Atlassian + BitBucket Server (formerly known as Atlassian Stash) hook. + + **Warning:** this mode was provided by a third-party contributor + and never tested by the git-multimail maintainers. It is + provided as-is and may or may not work for you. + + This value is automatically assumed when the stash-specific + flags (``--stash-user`` and ``--stash-repo``) are specified on + the command line. When this environment is active, the username + and repo come from these two command line flags, which must be + specified. + + gerrit + Environment to use when ``git-multimail`` is ran as a + ``ref-updated`` Gerrit hook. + + This value is used when the gerrit-specific command line flags + (``--oldrev``, ``--newrev``, ``--refname``, ``--project``) for + gerrit's ref-updated hook are present. When this environment is + active, the username of the pusher is taken from the + ``--submitter`` argument if that command line option is passed, + otherwise 'Gerrit' is used. The repository name is taken from + the ``--project`` option on the command line, which must be passed. + + For more information about gerrit and git-multimail, read + ``__ + + If none of these environments is suitable for your setup, then you + can implement a Python class that inherits from Environment and + instantiate it via a script that looks like the example + post-receive script. + + The environment value can be specified on the command line using + the ``--environment`` option. If it is not specified on the + command line or by ``multimailhook.environment``, the value is + guessed as follows: + + * If stash-specific (respectively gerrit-specific) command flags + are present on the command-line, then ``stash`` (respectively + ``gerrit``) is used. + + * If the environment variables $GL_USER and $GL_REPO are set, then + ``gitolite`` is used. + + * If none of the above apply, then ``generic`` is used. + +multimailhook.repoName + A short name of this Git repository, to be used in various places + in the notification email text. The default is to use $GL_REPO + for gitolite repositories, or otherwise to derive this value from + the repository path name. + +multimailhook.mailingList + The list of email addresses to which notification emails should be + sent, as RFC 2822 email addresses separated by commas. This + configuration option can be multivalued. Leave it unset or set it + to the empty string to not send emails by default. The next few + settings can be used to configure specific address lists for + specific types of notification email. + +multimailhook.refchangeList + The list of email addresses to which summary emails about + reference changes should be sent, as RFC 2822 email addresses + separated by commas. This configuration option can be + multivalued. The default is the value in + multimailhook.mailingList. Set this value to "none" (or the empty + string) to prevent reference change emails from being sent even if + multimailhook.mailingList is set. + +multimailhook.announceList + The list of email addresses to which emails about new annotated + tags should be sent, as RFC 2822 email addresses separated by + commas. This configuration option can be multivalued. The + default is the value in multimailhook.refchangeList or + multimailhook.mailingList. Set this value to "none" (or the empty + string) to prevent annotated tag announcement emails from being sent + even if one of the other values is set. + +multimailhook.commitList + The list of email addresses to which emails about individual new + commits should be sent, as RFC 2822 email addresses separated by + commas. This configuration option can be multivalued. The + default is the value in multimailhook.mailingList. Set this value + to "none" (or the empty string) to prevent notification emails about + individual commits from being sent even if + multimailhook.mailingList is set. + +multimailhook.announceShortlog + If this option is set to true, then emails about changes to + annotated tags include a shortlog of changes since the previous + tag. This can be useful if the annotated tags represent releases; + then the shortlog will be a kind of rough summary of what has + happened since the last release. But if your tagging policy is + not so straightforward, then the shortlog might be confusing + rather than useful. Default is false. + +multimailhook.commitEmailFormat + The format of email messages for the individual commits, can be "text" or + "html". In the latter case, the emails will include diffs using colorized + HTML instead of plain text used by default. Note that this currently the + ref change emails are always sent in plain text. + + Note that when using "html", the formatting is done by parsing the + output of ``git log`` with ``-p``. When using + ``multimailhook.commitLogOpts`` to specify a ``--format`` for + ``git log``, one may get false positive (e.g. lines in the body of + the message starting with ``+++`` or ``---`` colored in red or + green). + + By default, all the message is HTML-escaped. See + ``multimailhook.htmlInIntro`` to change this behavior. + +multimailhook.commitBrowseURL + Used to generate a link to an online repository browser in commit + emails. This variable must be a string. Format directives like + ``%()s`` will be expanded the same way as template + strings. In particular, ``%(id)s`` will be replaced by the full + Git commit identifier (40-chars hexadecimal). + + If the string does not contain any format directive, then + ``%(id)s`` will be automatically added to the string. If you don't + want ``%(id)s`` to be automatically added, use the empty format + directive ``%()s`` anywhere in the string. + + For example, a suitable value for the git-multimail project itself + would be + ``https://github.com/git-multimail/git-multimail/commit/%(id)s``. + +multimailhook.htmlInIntro, multimailhook.htmlInFooter + When generating an HTML message, git-multimail escapes any HTML + sequence by default. This means that if a template contains HTML + like ``link``, the reader will see the HTML + source code and not a proper link. + + Set ``multimailhook.htmlInIntro`` to true to allow writing HTML + formatting in introduction templates. Similarly, set + ``multimailhook.htmlInFooter`` for HTML in the footer. + + Variables expanded in the template are still escaped. For example, + if a repository's path contains a ``<``, it will be rendered as + such in the message. + + Read ``__ for more details and + examples. + +multimailhook.refchangeShowGraph + If this option is set to true, then summary emails about reference + changes will additionally include: + + * a graph of the added commits (if any) + + * a graph of the discarded commits (if any) + + The log is generated by running ``git log --graph`` with the options + specified in graphOpts. The default is false. + +multimailhook.refchangeShowLog + If this option is set to true, then summary emails about reference + changes will include a detailed log of the added commits in + addition to the one line summary. The log is generated by running + ``git log`` with the options specified in multimailhook.logOpts. + Default is false. + +multimailhook.mailer + This option changes the way emails are sent. Accepted values are: + + * **sendmail (the default)**: use the command ``/usr/sbin/sendmail`` or + ``/usr/lib/sendmail`` (or sendmailCommand, if configured). This + mode can be further customized via the following options: + + multimailhook.sendmailCommand + The command used by mailer ``sendmail`` to send emails. Shell + quoting is allowed in the value of this setting, but remember that + Git requires double-quotes to be escaped; e.g.:: + + git config multimailhook.sendmailcommand '/usr/sbin/sendmail -oi -t -F \"Git Repo\"' + + Default is '/usr/sbin/sendmail -oi -t' or + '/usr/lib/sendmail -oi -t' (depending on which file is + present and executable). + + multimailhook.envelopeSender + If set then pass this value to sendmail via the -f option to set + the envelope sender address. + + * **smtp**: use Python's smtplib. This is useful when the sendmail + command is not available on the system. This mode can be + further customized via the following options: + + multimailhook.smtpServer + The name of the SMTP server to connect to. The value can + also include a colon and a port number; e.g., + ``mail.example.com:25``. Default is 'localhost' using port 25. + + multimailhook.smtpUser, multimailhook.smtpPass + Server username and password. Required if smtpEncryption is 'ssl'. + Note that the username and password currently need to be + set cleartext in the configuration file, which is not + recommended. If you need to use this option, be sure your + configuration file is read-only. + + multimailhook.envelopeSender + The sender address to be passed to the SMTP server. If + unset, then the value of multimailhook.from is used. + + multimailhook.smtpServerTimeout + Timeout in seconds. Default is 10. + + multimailhook.smtpEncryption + Set the security type. Allowed values: ``none``, ``ssl``, ``tls`` (starttls). + Default is ``none``. + + multimailhook.smtpCACerts + Set the path to a list of trusted CA certificate to verify the + server certificate, only supported when ``smtpEncryption`` is + ``tls``. If unset or empty, the server certificate is not + verified. If it targets a file containing a list of trusted CA + certificates (PEM format) these CAs will be used to verify the + server certificate. For debian, you can set + ``/etc/ssl/certs/ca-certificates.crt`` for using the system + trusted CAs. For self-signed server, you can add your server + certificate to the system store:: + + cd /usr/local/share/ca-certificates/ + openssl s_client -starttls smtp \ + -connect mail.example.net:587 -showcerts \ + /dev/null \ + | openssl x509 -outform PEM >mail.example.net.crt + update-ca-certificates + + and used the updated ``/etc/ssl/certs/ca-certificates.crt``. Or + directly use your ``/path/to/mail.example.net.crt``. Default is + unset. + + multimailhook.smtpServerDebugLevel + Integer number. Set to greater than 0 to activate debugging. + +multimailhook.from, multimailhook.fromCommit, multimailhook.fromRefchange + If set, use this value in the From: field of generated emails. + ``fromCommit`` is used for commit emails, ``fromRefchange`` is + used for refchange emails, and ``from`` is used as fall-back in + all cases. + + The value for these variables can be either: + + - An email address, which will be used directly. + + - The value ``pusher``, in which case the pusher's address (if + available) will be used. + + - The value ``author`` (meaningful only for ``fromCommit``), in which + case the commit author's address will be used. + + If config values are unset, the value of the From: header is + determined as follows: + + 1. (gitolite environment only) + 1.a) If ``multimailhook.MailaddressMap`` is set, and is a path + to an existing file (if relative, it is considered relative to + the place where ``gitolite.conf`` is located), then this file + should contain lines like:: + + username Firstname Lastname + + git-multimail will then look for a line where ``$GL_USER`` + matches the ``username`` part, and use the rest of the line for + the ``From:`` header. + + 1.b) Parse gitolite.conf, looking for a block of comments that + looks like this:: + + # BEGIN USER EMAILS + # username Firstname Lastname + # END USER EMAILS + + If that block exists, and there is a line between the BEGIN + USER EMAILS and END USER EMAILS lines where the first field + matches the gitolite username ($GL_USER), use the rest of the + line for the From: header. + + 2. If the user.email configuration setting is set, use its value + (and the value of user.name, if set). + + 3. Use the value of multimailhook.envelopeSender. + +multimailhook.MailaddressMap + (gitolite environment only) + File to look for a ``From:`` address based on the user doing the + push. Defaults to unset. See ``multimailhook.from`` for details. + +multimailhook.administrator + The name and/or email address of the administrator of the Git + repository; used in FOOTER_TEMPLATE. Default is + multimailhook.envelopesender if it is set; otherwise a generic + string is used. + +multimailhook.emailPrefix + All emails have this string prepended to their subjects, to aid + email filtering (though filtering based on the X-Git-* email + headers is probably more robust). Default is the short name of + the repository in square brackets; e.g., ``[myrepo]``. Set this + value to the empty string to suppress the email prefix. You may + use the placeholder ``%(repo_shortname)s`` for the short name of + the repository. + +multimailhook.emailMaxLines + The maximum number of lines that should be included in the body of + a generated email. If not specified, there is no limit. Lines + beyond the limit are suppressed and counted, and a final line is + added indicating the number of suppressed lines. + +multimailhook.emailMaxLineLength + The maximum length of a line in the email body. Lines longer than + this limit are truncated to this length with a trailing ``[...]`` + added to indicate the missing text. The default is 500, because + (a) diffs with longer lines are probably from binary files, for + which a diff is useless, and (b) even if a text file has such long + lines, the diffs are probably unreadable anyway. To disable line + truncation, set this option to 0. + +multimailhook.subjectMaxLength + The maximum length of the subject line (i.e. the ``oneline`` field + in templates, not including the prefix). Lines longer than this + limit are truncated to this length with a trailing ``[...]`` added + to indicate the missing text. This option The default is to use + ``multimailhook.emailMaxLineLength``. This option avoids sending + emails with overly long subject lines, but should not be needed if + the commit messages follow the Git convention (one short subject + line, then a blank line, then the message body). To disable line + truncation, set this option to 0. + +multimailhook.maxCommitEmails + The maximum number of commit emails to send for a given change. + When the number of patches is larger that this value, only the + summary refchange email is sent. This can avoid accidental + mailbombing, for example on an initial push. To disable commit + emails limit, set this option to 0. The default is 500. + +multimailhook.excludeMergeRevisions + When sending out revision emails, do not consider merge commits (the + functional equivalent of `rev-list --no-merges`). + The default is `false` (send merge commit emails). + +multimailhook.emailStrictUTF8 + If this boolean option is set to `true`, then the main part of the + email body is forced to be valid UTF-8. Any characters that are + not valid UTF-8 are converted to the Unicode replacement + character, U+FFFD. The default is `true`. + + This option is ineffective with Python 3, where non-UTF-8 + characters are unconditionally replaced. + +multimailhook.diffOpts + Options passed to ``git diff-tree`` when generating the summary + information for ReferenceChange emails. Default is ``--stat + --summary --find-copies-harder``. Add -p to those options to + include a unified diff of changes in addition to the usual summary + output. Shell quoting is allowed; see ``multimailhook.logOpts`` for + details. + +multimailhook.graphOpts + Options passed to ``git log --graph`` when generating graphs for the + reference change summary emails (used only if refchangeShowGraph + is true). The default is '--oneline --decorate'. + + Shell quoting is allowed; see logOpts for details. + +multimailhook.logOpts + Options passed to ``git log`` to generate additional info for + reference change emails (used only if refchangeShowLog is set). + For example, adding -p will show each commit's complete diff. The + default is empty. + + Shell quoting is allowed; for example, a log format that contains + spaces can be specified using something like:: + + git config multimailhook.logopts '--pretty=format:"%h %aN <%aE>%n%s%n%n%b%n"' + + If you want to set this by editing your configuration file + directly, remember that Git requires double-quotes to be escaped + (see git-config(1) for more information):: + + [multimailhook] + logopts = --pretty=format:\"%h %aN <%aE>%n%s%n%n%b%n\" + +multimailhook.commitLogOpts + Options passed to ``git log`` to generate additional info for + revision change emails. For example, adding --ignore-all-spaces + will suppress whitespace changes. The default options are ``-C + --stat -p --cc``.

The shortcuts ``pusher`` and + ``author`` are allowed with the same semantics as for + ``multimailhook.from``. In addition, the value ``none`` can be + used to omit the ``Reply-To:`` field. + + The default is ``pusher`` for refchange emails, and ``author`` for + commit emails. + +multimailhook.quiet + Do not output the list of email recipients from the hook + +multimailhook.stdout + For debugging, send emails to stdout rather than to the + mailer.

They should work, but + the user-interface is not stable yet (in particular, the option + names may change). If you want to participate in stabilizing the + feature, please contact the maintainers and/or send pull-requests. + If you are happy with the current shape of the feature, please + report it too. + + Regular expressions that can be used to limit refs for which email + updates will be sent. It is an error to specify both an inclusion + and an exclusion regex. If a ``refFilterInclusionRegex`` is + specified, emails will only be sent for refs which match this + regex. If a ``refFilterExclusionRegex`` regex is specified, + emails will be sent for all refs except those that match this + regex (or that match a predefined regex specific to the + environment, such as "^refs/notes" for most environments and + "^refs/notes|^refs/changes" for the gerrit environment). + + The expressions are matched against the complete refname, and is + considered to match if any substring matches. For example, to + filter-out all tags, set ``refFilterExclusionRegex`` to + ``^refs/tags/`` (note the leading ``^`` but no trailing ``$``). If + you set ``refFilterExclusionRegex`` to ``master``, then any ref + containing ``master`` will be excluded (the ``master`` branch, but + also ``refs/tags/master`` or ``refs/heads/foo-master-bar``). + + ``refFilterDoSendRegex`` and ``refFilterDontSendRegex`` are + analogous to ``refFilterInclusionRegex`` and + ``refFilterExclusionRegex`` with one difference: with + ``refFilterDoSendRegex`` and ``refFilterDontSendRegex``, commits + introduced by one excluded ref will not be considered as new when + they reach an included ref. Typically, if you add a branch ``foo`` + to ``refFilterDontSendRegex``, push commits to this branch, and + later merge branch ``foo`` into ``master``, then the notification + email for ``master`` will contain a commit email only for the + merge commit. If you include ``foo`` in + ``refFilterExclusionRegex``, then at the time of merge, you will + receive one commit email per commit in the branch. + + These variables can be multi-valued, like:: + + [multimailhook] + refFilterExclusionRegex = ^refs/tags/ + refFilterExclusionRegex = ^refs/heads/master$ + + You can also provide a whitespace-separated list like:: + + [multimailhook] + refFilterExclusionRegex = ^refs/tags/ ^refs/heads/master$ + + Both examples exclude tags and the master branch, and are + equivalent to:: + + [multimailhook] + refFilterExclusionRegex = ^refs/tags/|^refs/heads/master$ + + ``refFilterInclusionRegex`` and ``refFilterExclusionRegex`` are + strictly stronger than ``refFilterDoSendRegex`` and + ``refFilterDontSendRegex``. In other words, adding a ref to a + DoSend/DontSend regex has no effect if it is already excluded by a + Exclusion/Inclusion regex. + +multimailhook.logFile, multimailhook.errorLogFile, multimailhook.debugLogFile + + When set, these variable designate path to files where + git-multimail will log some messages. Normal messages and error + messages are sent to ``logFile``, and error messages are also sent + to ``errorLogFile``. Debug messages and all other messages are + sent to ``debugLogFile``. The recommended way is to set only one + of these variables, but it is also possible to set several of them + (part of the information is then duplicated in several log files, + for example errors are duplicated to all log files). + + Relative path are relative to the Git repository where the push is + done. + +multimailhook.verbose + + Verbosity level of git-multimail on its standard output. By + default, show only error and info messages. If set to true, show + also debug messages. + +Email filtering aids +-------------------- + +All emails include extra headers to enable fine tuned filtering and +give information for debugging. All emails include the headers +``X-Git-Host``, ``X-Git-Repo``, ``X-Git-Refname``, and ``X-Git-Reftype``. +ReferenceChange emails also include headers ``X-Git-Oldrev`` and ``X-Git-Newrev``; +Revision emails also include header ``X-Git-Rev``. + + +Customizing email contents +-------------------------- + +git-multimail mostly generates emails by expanding templates. The +templates can be customized. To avoid the need to edit +``git_multimail.py`` directly, the preferred way to change the templates +is to write a separate Python script that imports ``git_multimail.py`` as +a module, then replaces the templates in place. See the provided +post-receive script for an example of how this is done. + + +Customizing git-multimail for your environment +---------------------------------------------- + +git-multimail is mostly customized via an "environment" that describes +the local environment in which Git is running. Two types of +environment are built in: + +GenericEnvironment + a stand-alone Git repository. + +GitoliteEnvironment + a Git repository that is managed by gitolite_. For such + repositories, the identity of the pusher is read from + environment variable $GL_USER, the name of the repository is read + from $GL_REPO (if it is not overridden by multimailhook.reponame), + and the From: header value is optionally read from gitolite.conf + (see multimailhook.from). + +By default, git-multimail assumes GitoliteEnvironment if $GL_USER and +$GL_REPO are set, and otherwise assumes GenericEnvironment. +Alternatively, you can choose one of these two environments explicitly +by setting a ``multimailhook.environment`` config setting (which can +have the value `generic` or `gitolite`) or by passing an --environment +option to the script. + +If you need to customize the script in ways that are not supported by +the existing environments, you can define your own environment class +class using arbitrary Python code. To do so, you need to import +``git_multimail.py`` as a Python module, as demonstrated by the example +post-receive script. Then implement your environment class; it should +usually inherit from one of the existing Environment classes and +possibly one or more of the EnvironmentMixin classes. Then set the +``environment`` variable to an instance of your own environment class +and pass it to ``run_as_post_receive_hook()``. + +The standard environment classes, GenericEnvironment and +GitoliteEnvironment, are in fact themselves put together out of a +number of mixin classes, each of which handles one aspect of the +customization. For the finest control over your configuration, you +can specify exactly which mixin classes your own environment class +should inherit from, and override individual methods (or even add your +own mixin classes) to implement entirely new behaviors. If you +implement any mixins that might be useful to other people, please +consider sharing them with the community! + + +Getting involved +---------------- + +Please, read ``__ for instructions on how to +contribute to git-multimail. + + +Footnotes +--------- + +.. [1] Because of the way information is passed to update hooks, the + script's method of determining whether a commit has already + been seen does not work when it is used as an ``update`` script. + In particular, no notification email will be generated for a + new commit that is added to multiple references in the same + push. A workaround is to use --force-send to force sending the + emails. + +.. _gitolite: https://github.com/sitaramc/gitolite diff --git a/contrib/hooks/multimail/doc/gitolite.rst b/contrib/hooks/multimail/doc/gitolite.rst index 00aedd9c57..5054833105 100644 --- a/contrib/hooks/multimail/doc/gitolite.rst +++ b/contrib/hooks/multimail/doc/gitolite.rst @@ -46,6 +46,15 @@ and add:: config multimailhook.mailingList = # Where emails should be sent config multimailhook.from = # From address to use +Note that by default, gitolite forbids ``<`` and ``>`` in variable +values (for security/paranoia reasons, see +`compensating for UNSAFE_PATT +`__ +in gitolite's documentation for explanations and a way to disable +this).
