[rt-users] experiences on perl 5.8.0 -> 5.8.3 upgrade

[Koos van den Hout]

Just for those seeking hints how to solve this..

I upgraded perl from 5.8.0. to 5.8.3 on our RT machine. I thought modules
would keep working, RT would keep working and I just would get uncorrupted
attachments in the process (we are trying to get other people to use RT for
mail handling who may have a positive stance towards html and .doc
attachments).

I got the following problems: internal server errors, empty pages on
updates, empty pages on search, search results missing from search pages,
and entries in the apache error_log:

I have things running again without these problems, by searching for perl
5.8.0 modules that were still used:

:/usr/lib/perl5/site_perl/5.8.0# find . -atime -1 -type f -ls

The big culprit seemed to be the DBI module. After a forced
remove/reinstall in a 5.8.3 environment, things started working normal
again. I also upgraded a lot of other modules in the process and recompiled
mod_perl (and apache).

I hope someone else can benefit from this ;)
