Hi, I was unable to start Bugzilla in mod_perl mode using Class::Load version 0.11 and 0.12. There were no error/warning messages, apache just wouldn't start. Reverting to version 0.10 solved the problem. Best I can tell, DateTime-Timezone-1.41 requires Class::Load. Perl: v5.8.8 built for x86_64-linux-thread-multi Machine: RHE5 2.6.18-238.12.1.el5xen #1 SMP, x86_64 I have no easy way to provide a test case. But I also reported the problem to the Bugzilla team: https://bugzilla.mozilla.org/show_bug.cgi?id=700219 Thanks, Albert -- IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.

Thanks for letting us know there's a problem (which will help us correlate data if more people report it), but there's really nothing we can do to help you without some indication of what the error is. Can you load DateTime in isolation, outside of Bugzilla, to see if that still causes an error?

No errors occurred when I had a separate script that loaded DateTime in isolation and called a DateTime function. Show quoted text

It seems likely that this may be the same as the bug I just submitted against DBD::Oracle and Module::Runtime: https://rt.cpan.org/Public/Bug/Display.html?id=72989 https://rt.cpan.org/Public/Bug/Display.html?id=72988 The short version is: if you load Module::Runtime and have an Oracle database connection open within mod_perl2, it will crash on start/restart (it seems to crash when Apache2 forks). I was not able to reproduce this bug with a SQLite database connection. I was assuming it was Oracle specific, but I did not try MySQL.

Oddly, I am not able to reproduce this issue on Ubuntu 9.10 with Perl version v5.10.0.

I narrowed it down. The problem only occurs if I statically compile mod_perl (httpd 2.2.21, mod_perl 2.0.5). If I dynamically load mod_perl, I am able to use the latest Class::Load version. -- IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.

I thought it was pretty standard (and safe) to use a dynamic mod_perl with Apache 2, unlike with Apache 1. I'm probably not going to look into this. It sounds like something a mod_perl hacker might have more success with.

This is a side effect of Params::Classify notbeing thread-safe. This is addressed in Class::Load 0.17, which requires a new Module::Require, which no longer uses Params::Classify (see also RT#72988).
