# Perl filter to handle the log messages from the checkin of files in
# a directory. This script will group the lists of files by log
# message, and mail a single consolidated log message at the end of
# the commit.
#
# This file assumes a pre-commit checking program that leaves the
# names of the first and last commit directories in a temporary file.
#
# IMPORTANT: what the above means is, this script interacts with
# commit_prep, in that they have to agree on the tmpfile name to use.
# See $LAST_FILE below.
#
# How this works: CVS triggers this script once for each directory
# involved in the commit -- in other words, a single commit can invoke
# this script N times. It knows when it's on the last invocation by
# examining the contents of $LAST_FILE. Between invocations, it
# caches information for its future incarnations in various temporary
# files in /tmp, which are named according to the process group and
# the committer (by themselves, neither of these are unique, but
# together they almost always are, unless the same user is doing two
# commits simultaneously). The final invocation is the one that
# actually sends the mail -- it gathers up the cached information,
# combines that with what it found out on this pass, and sends a
# commit message to the appropriate mailing list.
#
# (Ask Karl Fogel <kfogel@collab.net> if questions.)
#
# Contributed by David Hampton <hampton@cisco.com>
# Roy Fielding removed useless code and added log/mail of new files
# Ken Coar added special processing (i.e., no diffs) for binary files
