When I'm running Devel::Cover with ModPerl::Registry, I get no coverage info except for BEGIN blocks. When I'm running the same script with Devel::Cover from command line or as a CGI, everything works alright (obviously).
How can I make Devel::Cover "see" my code being executed in the runtime?
Here's Devel::Cover related stuff in my httpd.conf:
MaxClients 1
PerlSetEnv DEVEL_COVER_OPTIONS -db,/tmp/cover_db,silent,1
PerlRequire /var/www/project/startup.pl
Here's startup.pl:
#!/usr/bin/perl
use strict;
use warnings;
use Apache2::Directive ();
use File::Basename ();
use File::Find ();
BEGIN {
# Devel::Cover database must be writable by worker processes
my $conftree = Apache2::Directive::conftree->as_hash;
my $name = $conftree->{User}
or die "couldn't find user in Apache config";
print "user=$name\n";
my $uid = getpwnam($name);
defined $uid
or die "couldn't determine uid by name";
no warnings 'redefine';
local $> = $uid;
require Devel::Cover;
my $old_report = \&Devel::Cover::report;
*Devel::Cover::report = sub { local $> = $uid; $old_report->(@_) };
Devel::Cover->import;
}
1;
(As you may see, I made a monkey patch for Devel::Cover since startup.pl is being run by root, but worker processes run under a different user, and otherwise they couldn't read directories created by startup.pl. If you know a better solution, make a note, please.)
