Description Jiri Pirko 2009-10-15 14:59:17 UTC 
Created attachment 364932 [details]
test script

Description of problem:

When I use Fedora::Bugzilla->get_bug() to get a big BZ (e.g. with 4MB attachment), it gets stuck after a while and top shows ~99% cpu usage for this script. I use bz504799 to trigger this.

Version-Release number of selected component (if applicable):

0.10-1 - I tried 0.13 from CPAN and problem is still there.
How reproducible:
always

Steps to Reproduce:
run attached script
  
Actual results:
Script will never finish and consumes ~98% of cpu.

Expected results:
Script finishes.

Thanks for the reports!  I'm working on a number of enhancements/fixes, and will address these shortly.
Comment 2 Chris Weyl 2009-10-16 04:18:05 UTC 
Interesting -- Im "not authorized to access bug#504799".  Do you have another bug where you're seeing this?

Ups, this is private bz. I'll try to find another...
Comment 4 Jiri Pirko 2009-10-16 08:43:29 UTC 
ok - here's the bz you can use (16MB attachment) - bz515677
Comment 5 Chris Weyl 2009-10-18 07:55:21 UTC 
Hmmm....  Looks like this is actually an XML::Twig issue, reportes as rt35672; there's a 3.33 "development" kicking around on xmltwig.com that resolves this.

http://rt.cpan.org/Public/Bug/Display.html?id=35672
http://xmltwig.com/xmltwig/XML-Twig-3.33.tar.gz

I've filed another tix asking that it be "officially" released to the CPAN; if that happens we can easily update perl-XML-Twig...  If it doesn't, we should still look at updating perl-XML-Twig, as there are 2+ years of fixes/enhancements in there.
Comment 6 Jiri Pirko 2009-10-18 16:34:37 UTC 
Right, I installed XML-Twig-3.33.tar.gz and the issue does not occur.

Thanks Chris.
Comment 7 Marcela Mašláňová 2009-10-19 15:29:35 UTC 
I believe these bug fixes are valuable and we should update XML::Twig. In Changes are mainly bugfixes so I hope it will be ok.
Comment 8 Chris Weyl 2009-10-22 03:51:41 UTC 
Ok, so no response from the author.  I'm going to deploy 3.33 into production on a couple systems at work tomorrow and see what happens...  Assuming everything goes OK (as I believe it will) I'll update our package here.
Comment 9 Marcela Mašláňová 2009-10-22 07:38:47 UTC 
Um, I've already update to 0.33 in F-12 and rawhide. I believe with comparison to other Fedora updates, this is only small risk.
Comment 10 Chris Weyl 2009-10-22 14:44:03 UTC 
No problem. :) The author did just respond and state that he is going to cut a new GA release "ASAP", so hopefully we can switch over when that comes out.  (I have a feeling it's also going to be called 3.33)
Comment 11 Marcela Mašláňová 2010-02-09 12:32:31 UTC 
I'd like to close it as nextrelease (F-12).
