This way the hook doesn't have to keep being tweaked as porcelain learns new features like color and pagination. While at it, replace the "git rev-list | git shortlog" idiom with plain "git shortlog" for simplicity. Except for depending less on the value of settings like '[log] abbrevCommit', no change in output intended.

# An example hook script to mail out commit update information.
|
|
#
|
|
# NOTE: This script is no longer under active development. There
|
|
# is another script, git-multimail, which is more capable and
|
|
# configurable and is largely backwards-compatible with this script;
|
|
# please see "contrib/hooks/multimail/". For instructions on how to
|
|
# migrate from post-receive-email to git-multimail, please see
|
|
# "README.migrate-from-post-receive-email" in that directory.
|
|
#
|
|
# This hook sends emails listing new revisions to the repository
|
|
# introduced by the change being reported. The rule is that (for
|
|
# branch updates) each commit will appear on one email and one email
|
|
# only.
|
|
#
|
|
# This hook is stored in the contrib/hooks directory. Your distribution
|
|
# will have put this somewhere standard. You should make this script
|
|
# executable then link to it in the repository you would like to use it in.
|
|
# For example, on debian the hook is stored in
|
|
# /usr/share/git-core/contrib/hooks/post-receive-email:
|
|
#
|
|
# chmod a+x post-receive-email
|
|
# cd /path/to/your/repository.git
|
|
# ln -sf /usr/share/git-core/contrib/hooks/post-receive-email hooks/post-receive
|
|
#
|
|
# This hook script assumes it is enabled on the central repository of a
|
|
# project, with all users pushing only to it and not between each other. It
|
|
# will still work if you don't operate in that style, but it would become
|
|
# possible for the email to be from someone other than the person doing the
|
|
# push.
|
|
#
|
|
# To help with debugging and use on pre-v1.5.1 git servers, this script will
|
|
# also obey the interface of hooks/update, taking its arguments on the
|
|
# command line. Unfortunately, hooks/update is called once for each ref.
|
|
# To avoid firing one email per ref, this script just prints its output to
|
|
# the screen when used in this mode. The output can then be redirected if
|
|
# wanted.
|
|
#
|
|
# Config
|
|
# ------
|
|
# hooks.mailinglist
|
|
# This is the list that all pushes will go to; leave it blank to not send
|
|
# emails for every ref update.
|
|
# hooks.announcelist
|
|
# This is the list that all pushes of annotated tags will go to. Leave it
|
|
# blank to default to the mailinglist field. The announce emails lists
|
|
# the short log summary of the changes since the last annotated tag.
|
|
# hooks.envelopesender
|
|
# If set then the -f option is passed to sendmail to allow the envelope
|
|
# sender address to be set
|
|
# hooks.emailprefix
|
|
# All emails have their subjects prefixed with this prefix, or "[SCM]"
|
|
# if emailprefix is unset, to aid filtering
|
|
# hooks.showrev
|
|
# The shell command used to format each revision in the email, with
|
|
# "%s" replaced with the commit id. Defaults to "git rev-list -1
|
|
# --pretty %s", displaying the commit id, author, date and log
|
|
# message. To list full patches separated by a blank line, you
|
|
# could set this to "git show -C %s; echo".
|
|
# To list a gitweb/cgit URL *and* a full patch for each change set, use this:
|
|
# "t=%s; printf 'http://.../?id=%%s' \$t; echo;echo; git show -C \$t; echo"
|
|
# Be careful if "..." contains things that will be expanded by shell "eval"
|
|
# or printf.
|
|
# hooks.emailmaxlines
|
|
# The maximum number of lines that should be included in the generated
|
|
# email body. 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.
|
|
# hooks.diffopts
|
|
# Alternate options for the git diff-tree invocation that shows changes.
|
|
# 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.
|
|
#
|
|
# Notes
|
|
# -----
|
|
# All emails include the headers "X-Git-Refname", "X-Git-Oldrev",
|
|
# "X-Git-Newrev", and "X-Git-Reftype" to enable fine tuned filtering and
|
|
# give information for debugging.

# O is $oldrev for $refname
|
|
# N is $newrev for $refname
|
|
# X is a revision pointed to by some other ref, for which we may
|
|
# assume that an email has already been generated.
|
|
# In this case we want to issue an email containing only revisions
|
|
# 3, 4, and N. Given (almost) by
|
|
#
|
|
# git rev-list N ^O --not --all
|
|
#
|
|
# The reason for the "almost", is that the "--not --all" will take
|
|
# precedence over the "N", and effectively will translate to
|
|
#
|
|
# git rev-list N ^O ^X ^N
|
|
#
|
|
# So, we need to build up the list more carefully. git rev-parse
|
|
# will generate a list of revs that may be fed into git rev-list.
|
|
# We can get it to make the "--not --all" part and then filter out
|
|
# the "^N" with:
|
|
#
|
|
# git rev-parse --not --all | grep -v N
|
|
#
|
|
# Then, using the --stdin switch to git rev-list we have effectively
|
|
# manufactured
|
|
#
|
|
# git rev-list N ^O ^X
|
|
#
|
|
# This leaves a problem when someone else updates the repository
|
|
# while this script is running. Their new value of the ref we're
|
|
# working on would be included in the "--not --all" output; and as
|
|
# our $newrev would be an ancestor of that commit, it would exclude
|
|
# all of our commits. What we really want is to exclude the current
|
|
# value of $refname from the --not list, rather than N itself. So:
|
|
#
|
|
# git rev-parse --not --all | grep -v $(git rev-parse $refname)
|
|
#
|
|
# Get's us to something pretty safe (apart from the small time
|
|
# between refname being read, and git rev-parse running - for that,
|
|
# I give up)
|
|
#
|
|
#
|
|
# Next problem, consider this:
|
|
# * --- B --- * --- O ($oldrev)
|
|
# \
|
|
# * --- X --- * --- N ($newrev)
|
|
#
|
|
# That is to say, there is no guarantee that oldrev is a strict
|
|
# subset of newrev (it would have required a --force, but that's
|
|
# allowed). So, we can't simply say rev-list $oldrev..$newrev.
|
|
# Instead we find the common base of the two revs and list from
|
|
# there.
|
|
#
|
|
# As above, we need to take into account the presence of X; if
|
|
# another branch is already in the repository and points at some of
|
|
# the revisions that we are about to output - we don't want them.
|
|
# The solution is as before: git rev-parse output filtered.
|
|
#
|
|
# Finally, tags: 1 --- 2 --- O --- T --- 3 --- 4 --- N
|
|
#
|
|
# Tags pushed into the repository generate nice shortlog emails that
|
|
# summarise the commits between them and the previous tag. However,
|
|
# those emails don't include the full commit messages that we output
|
|
# for a branch update. Therefore we still want to output revisions
|
|
# that have been output on a tag email.
|
|
#
|
|
# Luckily, git rev-parse includes just the tool. Instead of using
|
|
# "--all" we use "--branches"; this has the added benefit that
|
|
# "remotes/" will be ignored as well.
|
|
|
|
# List all of the revisions that were removed by this update, in a
