Description Igor Foox 2006-02-02 16:57:15 UTC 
Description of problem:
The plugin cannot refresh 2 bugs at the same time from one bugzilla. Small 'x'
icons appear on the bugs and their information is not fetched.

Version-Release number of selected component (if applicable):
0.1.2

How reproducible:
Almost always. Sometimes doesn't happen in an unpredictable fasion.

Steps to Reproduce:
1.Make query with more than 1 result.
2.Select group of bugs, right click, hit Refresh.
3.While previous group still refreshin, select another group, right-click, hit
Refresh.
  
Actual results:
Red 'x' icons appear on all/some icons of the bugs that should be refreshed. No
info is fetched. Sometimes an error message pops up.

Expected results:
No erros, multiple bugs fetched simultaneously.

Additional info:

This seems to be happening in the HTTPConnection.ConnectingThread class in the
getStream() method.

This might be more than one bug in a relaed area of code, but here's one path
through the code that breaks it.

Comment 4 Igor Foox 2006-02-02 19:49:20 UTC 
Tom, could you take a look? Maybe you would be able to figure out where the
problem is occuring here.
Comment 5 Igor Foox 2006-02-02 20:17:45 UTC 
I can't reproduce this with the lateset gcc from rawhide (4.1.0-0.18), so it may
be something that's fixed there.

With 4.0 I see:

This sounds vaguely familiar, I think it is a known http protocol
handler bug that was fixed for 4.1.  I can't reproduce with my 4.1 gcj.

Unless you need this fixed in 4.0.x, I am going to stop looking at it now.
We could close it as fixed/rawhide, what do you think?
Comment 7 Igor Foox 2006-02-07 21:05:26 UTC 
It's not very high-priority, so I'll close this as fixed/rawhide. If you happen
to have to have a lot of free time on your hands it'd be nice to be fix this ;-).
