perl script inside apache configuration, svn example
For every svn project you have a <Location> section in your apache configuration. Whenever you add a svn project you have to manually add a section in that configuration file.
The configuration file gets very long and whenever you have to change something you have to change it for every project.
You can write a script that generates the big file, but when you add a repositorie you have to run the script and restart apache.
This can be solved by adding a “perl script” inside the apache configuration. First you have to install the mod_perl which allows you to use the module “mod_perl.c”.
Now you can write some perl scripts inside your apache configuration, these scripts will be executed whenever the configuration file is parsed (with a restart/reload).
This is how the mod_perl section in my configuration looks like:
<IfModule mod_perl.c>
<Perl>
#!/usr/bin/perl
sub loop_dir {
my $base = shift;
my $sub = shift;
if($sub) { $sub .= "/";}
opendir(DIR, "$base$sub")
or die "Unable to open SVN repository base '$base$sub'\n";
foreach $project (readdir(DIR)) {
next unless $project =~ /^[[:alnum:]_\-]+$/;
next unless -d "$base$sub$project";
if( -e "$base$sub$project/format"){
print "\nHandling project: $sub$project";
$Location{"/$sub$project"} = {
DAV => 'svn',
SVNPath => "$base$sub$project",
AuthType => 'Basic',
AuthName => "'Cronos CVSVN server'",
AuthLDAPAuthoritative => 'on',
AuthLDAPURL => ' ldap://localhost/ou=users,dc=cronos,dc=be?uid',
AuthLDAPGroupAttribute => 'memberUid',
AuthLDAPGroupAttributeIsDN => 'off',
Require => "group cn=$project,ou=groups,dc=cronos,dc=be",
}
} else {
&loop_dir("$base", "$sub$project");
}
}
closedir(DIR);
}
&loop_dir ('/var/lib/svn/');
</Perl>
</IfModule>
This part of the configuration file will create a <Location> section for every svn-project inside /var/lib/svn it will also looks inside the subdirectories (if the directory is not a project).
