Grubbs) -# Branch specific controls added by voisine@bytemobile.com (Aaron Voisine) -# -# CVS "commitinfo" for matching repository names, running the program it finds -# on the same line. More information is available in the CVS man pages. -# -# ==== INSTALLATION: -# -# To use this program as I intended, do the following four things: -# -# 0. Install PERL. :-) -# -# 1. Put one line, as the *only* non-comment line, in your commitinfo file: -# -# DEFAULT /usr/local/bin/cvs_acls -# -# 2. Install this file as /usr/local/bin/cvs_acls and make it executable. -# -# 3. Create a file named $CVSROOT/CVSROOT/avail. -# -# ==== FORMAT OF THE avail FILE: -# -# The avail file determines whether you may commit files. It contains lines -# read from top to bottom, keeping track of a single "bit". The "bit" -# defaults to "on". It can be turned "off" by "unavail" lines and "on" by -# "avail" lines. ==> Last one counts. -# -# Any line not beginning with "avail" or "unavail" is ignored. -# -# Lines beginning with "avail" or "unavail" are assumed to be '|'-separated -# triples: (All spaces and tabs are ignored in a line.) -# -# {avail.*,unavail.*} [|user,user,... [|repos,repos,... [|branch,branch,...]]] -# -# 1. String starting with "avail" or "unavail". -# 2. Optional, comma-separated list of usernames. -# 3. Optional, comma-separated list of repository pathnames. -# These are pathnames relative to $CVSROOT. They can be directories or -# filenames. A directory name allows access to all files and -# directories below it. -# 4. Optional, comma-separated list of branch tags. -# If not specified, all branches are assumed. Use HEAD to reference the -# main branch. -# -# Example: (Text from the ';;' rightward may not appear in the file.) -# -# unavail ;; Make whole repository unavailable. -# avail|dgg ;; Except for user "dgg". -# avail|fred, john|bin/ls ;; Except when "fred" or "john" commit to -# ;; the module whose repository is "bin/ls" -# avail|ed|/bin/ls|stable ;; Except when "ed" commits to the "stable" -# ;; branch of the "bin/ls" repository -# -# PROGRAM LOGIC: -# -# CVS passes to @ARGV an absolute directory pathname (the repository -# appended to your $CVSROOT variable), followed by a list of filenames -# within that directory. -# -# We walk through the avail file looking for a line that matches the -# username, repository and branch. -# -# A username match is simply the user's name appearing in the second -# column of the avail line in a space-or-comma separate list. -# -# A repository match is either: -# - One element of the third column matches $ARGV[0], or some -# parent directory of $ARGV[0]. -# - Otherwise *all* file arguments ($ARGV[1..$#ARGV]) must be -# in the file list in one avail line. -# - In other words, using directory names in the third column of -# the avail file allows committing of any file (or group of -# files in a single commit) in the tree below that directory. -# - If individual file names are used in the third column of -# the avail file, then files must be committed individually or -# all files specified in a single commit must all appear in -# third column of a single avail line. -# -# A branch match is either: -# - When no branches are listed in the fourth column. -# - One element from the fourth column matches each of the tag -# names for $ARGV[1..$#ARGV] found in the CVS/Entries file. -# - HEAD specified in the fourth column will match if there -# is no tag listed in the CVS/Entries file. -# - -$debug = 0; -$cvsroot = $ENV{'CVSROOT'}; -$availfile = $cvsroot .
