Description Al Puzzuoli 2006-05-16 19:05:00 UTC

Steps to reproduce:
I have seen this behavior on both a Ubuntu dapper, as well as a Debian Sid 
system.  It does not occur 100% of the time, but it should happen often enough 
to be very easily reproduceable:

1.  log into gnome as root and run synaptic
2. Press the reload button or alternatively, select several packages for 
installation, and then apply changes.
The crash recorded in the attached log happened when I pressed the reload 
button.
When these hangs occur, it is possible to restore functionality by killing, and 
then reloading orca.

Potential fix for the hang

In debugging this, it seems as though synaptic loves to create and destroy windows as it shows the progress of an upgrade or install.  This seems to cause issues with the desktop from time to time, causing sporadic CORBA COMM_FAILURES to occur when accessing the desktop.  This particular problem seems to occur when orca attempts to reclaim scripts for destroyed windows.  This patch provides a defensive mechanism against these failures - if a failure occurs while attempting to reclaim a script, the routine will just stop trying what it is doing and return.  The logic here is that the desktop will eventually come back to life and the next time the reclaim is done, it will be likely to be more successful.  This appears to fix the hang, but it of course does nothing to improve the general usability of synpatic - that will probably require a script.

debug log for the described hang.

I am still experiencing instability here.  I did a synaptic run, and was able to complete the installation process of a package; However, After the process completed, Orca became unstable, and ultimately hung.   I was able to use flat review to determine that all changes had been applied successfully, but then, I was either unable to close the Synaptic Window, or Orca didn't reflect that it had closed.  I fiddled a bit more with flat review, whereupon Orca hung.  A debug log is attached.

Comment 4 Willie Walker 2006-07-26 15:09:47 UTC

Now that we've added the "don't look at DEFUNCT" objects patch, I took a look at this bug again.  What I've noticed is that Orca slows waaaay down in its processing of events from synaptic (either that or synaptic is flooding orca with zillions of events), but Orca eventually will speak after a few minutes of chunking through the storm.  I'm tempted to replace "hang" in the title with "slows down quite measurably", but I'd like to verify with you that you are now seeing a huge slow down versus a hang with the Orca from GNOME CVS HEAD.

If you get a chance, can you please try the latest code?

Comment 5 Rich Burridge 2006-08-01 00:49:54 UTC

Al, I've just retried this with the latest Orca from CVS HEAD on
Ubuntu Dapper Drake (v6.06) with DECtalk 4.64 as my TTS. I logged
in as root and ran "synaptic" from a terminal window. I followed
the instructions you gave and didn't have any hangs or slow downs
or any other problems. It looks like this problem is now fixed.

Could you please confirm this and I'll close out the bug?  Thanks.

Comment 6 Mike Pedersen 2006-08-01 01:07:46 UTC

Hey Rich, you might want to give this one several run-throughs as some times it works fine.  A good way to test this is by arrowing through lots of packages and selecting some for install.  At some time orca will probably slow down or hang.  Be sure to monitor the whole install process as some times the problem shows up later in the process.

Comment 7 Rich Burridge 2006-08-01 15:56:01 UTC

Mike, I'm not seeing this/these problems. Has the problem
occured for you since Will changed the GIL timeout from 0.0001
to 0.00001?

Comment 8 Willie Walker 2006-08-10 16:33:32 UTC

I can no longer reproduce this with the latest Orca.  Are you still able to reproduce this?

Comment 9 Mike Pedersen 2006-08-16 18:45:55 UTC

I just ran synaptic several times and did not hang.

Comment 10 Willie Walker 2006-08-16 19:02:25 UTC

Based upon Mike's testing, I'm going to close this one out as fixed.  If we come across it again, however, please re-open.
