Hi Rakesh,

The way that I implemented this was to have the perl script that is
run by commitinfo read the CVS/Entries file

# start perl code extract


use strict;
use vars qw(%lockedbranch %cvsbranch %branchtag);

# the list of locked branches ... may also be read from a file
# like $CVSROOT/lockedbranches or something if desired
my @lockedbranches = qw(release_1 release_2 release_1a);
foreach my $key (@lockedbranches) {
    $lockedbranch{$key} = 1;

if (open(ENTRIES, 'CVS/Entries')) {
    my $ent;
    while ($ent = <ENTRIES>) {
        # /file/ver/timestamp/options/tag_or_date
        my(undef, $filename, $version, $ts, $opt, $tag) = split('/', $ent);
        if ($tag =~ /^T(.*)/) {
            # tag indication
            $cvsbranch{$filename} = $1;
        } elsif ($tag eq '') {
            $cvsbranch{$filename} = '';
        } else {
            $cvsbranch{$filename} = $tag;
} else {
    die("Cannot open CVS/Entries.\n");

my $directory = $ARGV[0];
shift @ARGV;

my $die = 0;
foreach my $arg (@ARGV) {
    if ($lockedbranch{$cvsbranch{$arg}}) {
        print STDERR "$directory/$arg is on a locked branch\n";
        $die = 1 unless ($directory eq 'CVSROOT');

exit 1 if ($die);

#...perform other commitinfo checks here...

exit 0;

# end perl code extract

Of course, this may not be the most optimal method (and I didn't
actually test this particular code example), but you should be able
get the idea of how to do the job from it.

        Good luck,
        -- Mark
