Subject: remove git/ directory
X-Git-Url: http://repo.macrolet.net/gitweb/?a=commitdiff_plain;h=e494c66720ee54082aee7870c77ee963ddf9bb40;p=sbcl.git

remove git/ directory

The scripts therein weren't directly relevant for SBCL development,
only for infrastructure to assist that development; additionally,
they are derived from git examples licensed under the GPL, and it
was difficult to explain the effects of this in a short paragraph
in the master COPYING file.  A new sbcl-git-hooks repository is
available on SourceForge for these and any other infrastructure
customizations.

-#
-# (Modified for SBCL.)
-#
-# Copyright (c) 2007 Andy Parkins
-#
-# An example hook script to mail out commit update information.  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 fedora 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.
-#
-# 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.
-#
-# 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.

-# this is and calls the appropriate body-generation routine after outputting
-# the common header

-# taken care of by the functions it calls:
-#  - generate_email_header

-#  - generate_delete_XXXX_email

-	# 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
