5 # An example hook script to mail out commit update information. This hook
6 # sends emails listing new revisions to the repository introduced by the
7 # change being reported. The rule is that (for branch updates) each commit
8 # will appear on one email and one email only.
11 # This is Girocco-customized version. No matter what is said below, it has
13 # * Calling with arguments is same as giving them on stdin.
14 # * Optional fourth parameter is project name, used at most places instead
16 # * Optional fifth parameter is email sender.
17 # * Optional sixth parameter is extra e-mail header to add.
18 # * If MAIL_SH_OTHER_BRANCHES is set it is taken as branch tips of already seen
19 # revisions when running show_new_revisions and mail.sh skips its own
20 # computation. If it starts with '@' the rest is the hash of a blob that
21 # contains the information (one tip per line).
22 # If MAIL_SH_OTHER_BRANCHES is not set, guess at what they are.
23 # MAIL_SH_OTHER_BRANCHES is ignored if updates are piped in via stdin.
25 # * Default subject prefix is site name.
26 # * Unsubscribe instructions in email footer.
27 # * Default showrev includes gitweb link and show -C.
28 # * Nicer subject line.
29 # * Limit mail size to 256kb.
32 # This hook is stored in the contrib/hooks directory. Your distribution
33 # will have put this somewhere standard. You should make this script
34 # executable then link to it in the repository you would like to use it in.
35 # For example, on debian the hook is stored in
36 # /usr/share/git-core/contrib/hooks/post-receive-email:
38 # chmod a+x post-receive-email
39 # cd /path/to/your/repository.git
40 # ln -sf /usr/share/git-core/contrib/hooks/post-receive-email hooks/post-receive
42 # This hook script assumes it is enabled on the central repository of a
43 # project, with all users pushing only to it and not between each other. It
44 # will still work if you don't operate in that style, but it would become
45 # possible for the email to be from someone other than the person doing the
51 # This is the list that all pushes will go to; leave it blank to not send
52 # emails for every ref update.
54 # If true new revisions are shown in reverse order (i.e. oldest to newest)
56 # If true do not include the actual diff when showing new commits (the
57 # summary information will still be shown). Default is false.
59 # This is the list that all pushes of annotated tags will go to. Leave it
60 # blank to default to the mailinglist field. The announce emails lists
61 # the short log summary of the changes since the last annotated tag.
62 # hooks.envelopesender
63 # If set then the -f option is passed to sendmail to allow the envelope
64 # sender address to be set
66 # All emails have their subjects prefixed with this prefix, or "[SCM]"
67 # if emailprefix is unset, to aid filtering
69 # The shell command used to format each revision in the email, with
70 # "%s" replaced with the commit id. Defaults to "git rev-list -1
71 # --pretty %s", displaying the commit id, author, date and log
72 # message. To list full patches separated by a blank line, you
73 # could set this to "git show -C %s; echo".
74 # To list a gitweb/cgit URL *and* a full patch for each change set, use this:
75 # "t=%s; printf 'http://.../?id=%%s' \$t; echo;echo; git show -C \$t; echo"
76 # Be careful if "..." contains things that will be expanded by shell "eval"
81 # All emails include the headers "X-Git-Refname", "X-Git-Oldrev",
82 # "X-Git-Newrev", and "X-Git-Reftype" to enable fine tuned filtering and
83 # give information for debugging.

429 # In this case we want to issue an email containing only revisions
430 # 3, 4, and N. Given (almost) by
432 # git rev-list N ^O --not --all
434 # The reason for the "almost", is that the "--not --all" will take
435 # precedence over the "N", and effectively will translate to
437 # git rev-list N ^O ^X ^N
439 # So, we need to build up the list more carefully. git rev-parse
440 # will generate a list of revs that may be fed into git rev-list.
441 # We can get it to make the "--not --all" part and then filter out
444 # git rev-parse --not --all | grep -v N
446 # Then, using the --stdin switch to git rev-list we have effectively
449 # git rev-list N ^O ^X
451 # This leaves a problem when someone else updates the repository
452 # while this script is running. Their new value of the ref we're
453 # working on would be included in the "--not --all" output; and as
454 # our $newrev would be an ancestor of that commit, it would exclude
455 # all of our commits. What we really want is to exclude the current
456 # value of $refname from the --not list, rather than N itself. So:
458 # git rev-parse --not --all | grep -v $(git rev-parse $refname)
460 # Get's us to something pretty safe (apart from the small time
461 # between refname being read, and git rev-parse running - for that,
465 # Next problem, consider this:
466 # * --- B --- * --- O ($oldrev)
468 # * --- X --- * --- N ($newrev)
470 # That is to say, there is no guarantee that oldrev is a strict
471 # subset of newrev (it would have required a --force, but that's
472 # allowed). So, we can't simply say rev-list $oldrev..$newrev.
473 # Instead we find the common base of the two revs and list from
476 # As above, we need to take into account the presence of X; if
477 # another branch is already in the repository and points at some of
478 # the revisions that we are about to output - we don't want them.
479 # The solution is as before: git rev-parse output filtered.
481 # Finally, tags: 1 --- 2 --- O --- T --- 3 --- 4 --- N
483 # Tags pushed into the repository generate nice shortlog emails that
484 # summarise the commits between them and the previous tag. However,
485 # those emails don't include the full commit messages that we output
486 # for a branch update. Therefore we still want to output revisions
487 # that have been output on a tag email.
