This hook sends emails describing changes introduced by pushes to a git repository. For each reference that was changed, it emits one ReferenceChange email summarizing how the reference was changed, followed by one Revision email for each new commit that was introduced by the reference change. Each commit is announced in exactly one Revision email. If the same commit is merged into another branch in the same or a later push, then the ReferenceChange email will list the commit's SHA1 and its one-line summary, but no new Revision email will be generated. This script is designed to be used as a "post-receive" hook in a git repository (see githooks(5)). It can also be used as an "update" script, but this usage is not completely reliable and is deprecated. To help with debugging, this script accepts a --stdout option, which causes the emails to be written to standard output rather than sent using sendmail. See the accompanying README file for the complete documentation. iN(t make_msgid(t getaddresses(t formataddr(tHeadert0i(sH- Log ----------------------------------------------------------------- sH----------------------------------------------------------------------- tfromttotcctbccsreply-totsendersUTF-8sutf-8sP%(emailprefix)s%(refname_type)s %(short_refname)s created (now %(newrev_short)s)s`%(emailprefix)s%(refname_type)s %(short_refname)s updated (%(oldrev_short)s -> %(newrev_short)s)sP%(emailprefix)s%(refname_type)s %(short_refname)s deleted (was %(oldrev_short)s)ssTo: %(recipients)s Subject: %(subject)s MIME-Version: 1.0 Content-Type: text/plain; charset=%(charset)s Content-Transfer-Encoding: 8bit Message-ID: %(msgid)s From: %(fromaddr)s Reply-To: %(reply_to)s X-Git-Repo: %(repo_shortname)s X-Git-Refname: %(refname)s X-Git-Reftype: %(refname_type)s X-Git-Oldrev: %(oldrev)s X-Git-Newrev: %(newrev)s Auto-Submitted: auto-generated sThis is an automated email from the git hooks/post-receive script. %(pusher)s pushed a change to %(refname_type)s %(short_refname)s in repository %(repo_shortname)s. s\ -- To stop receiving notification emails like this one, please contact %(administrator)s. syThis update removed existing revisions from the reference, leaving the reference pointing at a previous point in the repository history. * -- * -- N %(refname)s (%(newrev_short)s) \ O -- O -- O (%(oldrev_short)s) Any revisions marked "omits" are not gone; other references still refer to them.

An Environment object encapsulates information about the local environment. For example, it knows how to determine: * the name of the repository to which the push occurred * what user did the push * what users want to be informed about various types of changes. An Environment object is expected to have the following methods: get_repo_shortname() Return a short name for the repository, for display purposes. get_repo_path() Return the absolute path to the Git repository. get_emailprefix() Return a string that will be prefixed to every email's subject. get_pusher() Return the username of the person who pushed the changes. This value is used in the email body to indicate who pushed the change. get_pusher_email() (may return None) Return the email address of the person who pushed the changes. The value should be a single RFC 2822 email address as a string; e.g., "Joe User " if available, otherwise "user@example.com". If set, the value is used as the Reply-To address for refchange emails. If it is impossible to determine the pusher's email, this attribute should be set to None (in which case no Reply-To header will be output). get_sender() Return the address to be used as the 'From' email address in the email envelope. get_fromaddr() Return the 'From' email address used in the email 'From:' headers. (May be a full RFC 2822 email address like 'Joe User '.) get_administrator() Return the name and/or email of the repository administrator. This value is used in the footer as the person to whom requests to be removed from the notification list should be sent. Ideally, it should include a valid email address. get_reply_to_refchange() get_reply_to_commit() Return the address to use in the email "Reply-To" header, as a string. These can be an RFC 2822 email address, or None to omit the "Reply-To" header. get_reply_to_refchange() is used for refchange emails; get_reply_to_commit() is used for individual commit emails. They should also define the following attributes: announce_show_shortlog (bool) True iff announce emails should include a shortlog. refchange_showlog (bool) True iff refchanges emails should include a detailed log. diffopts (list of strings) The options that should be passed to 'git diff' for the summary email. The value should be a list of strings representing words to be passed to the command. logopts (list of strings) Analogous to diffopts, but contains options passed to 'git log' when generating the detailed log for a set of commits (see refchange_showlog) commitlogopts (list of strings) The options that should be passed to 'git log' for each commit mail.

It is easy to figure out what commits were added to a *branch* by a Reference change: git rev-list change.old..change.new or removed from a *branch*: git rev-list change.new..change.old But it is not quite so trivial to determine which entirely new commits were added to the *repository* by a push and which old commits were discarded by a push. A big part of the job of this class is to figure out these things, and to make sure that new commits are only detailed once even if they were added to multiple references. The first step is to determine the "other" references--those unaffected by the current push. They are computed by Push._compute_other_ref_sha1s() by listing all references then removing any affected by this push. The commits contained in the repository before this push were git rev-list other1 other2 other3 ... change1.old change2.old ... Where "changeN.old" is the old value of one of the references affected by this push. The commits contained in the repository after this push are git rev-list other1 other2 other3 ... change1.new change2.new ... The commits added by this push are the difference between these two sets, which can be written git rev-list ^other1 ^other2 ... ^change1.old ^change2.old ... change1.new change2.new ... The commits removed by this push can be computed by git rev-list ^other1 ^other2 ... ^change1.new ^change2.new ... change1.old change2.old ... The last point is that it is possible that other pushes are occurring simultaneously to this one, so reference values can change at any time. It is impossible to eliminate all race conditions, but we reduce the window of time during which problems can occur by translating reference names to SHA1s as soon as possible and working with SHA1s thereafter (because SHA1s are immutable).ccs!|]\}}||fVqdS(N((R<RxRU((s//home/cloos/live-x11.git/hooks/git_multimail.pys NsRRRcCsxt|d|j|_|j}|j|jd|jD|_|j|jd|jD|_dS(NRVcss-|]#}|jjdkr|jjVqdS(R|R}N(scommitstag(RRR(R<tchange((s//home/cloos/live-x11.git/hooks/git_multimail.pys gscss-|]#}|jjdkr|jjVqdS(R|R}N(scommitstag(RRR(R<R((s//home/cloos/live-x11.git/hooks/git_multimail.pys ns(Rpt _sort_keytchangest_compute_other_ref_sha1st_compute_rev_exclusion_spectuniont_old_rev_exclusion_spect_new_rev_exclusion_spec(RRtother_ref_sha1s((s//home/cloos/live-x11.git/hooks/git_multimail.pyR^s cCs |j|j|jf|jfS(N(t SORT_ORDERt __class__RR(RR((s//home/cloos/live-x11.git/hooks/git_multimail.pyRtscCstd|jD}t}d}xjtdd|fgD]O}|jdd\}}}|rB|dkrB||krB|j|qBqBW|S(sHReturn the GitObjects referred to by references unaffected by this push.css|]}|jVqdS(N(R(R<R((s//home/cloos/live-x11.git/hooks/git_multimail.pys }ssO%(objectname) %(objecttype) %(refname) %(*objectname) %(*objecttype) %(refname)s for-each-refs --format=%sR iR|(R]RR/RJR^(Rt updated_refsRtfmtRZRRR=((s//home/cloos/live-x11.git/hooks/git_multimail.pyRxs  cCs-djgt|D]}d|f^qS(sReturn an exclusion specification for 'git rev-list'. git_objects is an iterable over GitObject instances.
