Description Douglas Miles 2008-08-13 15:18:03 UTC

Description of problem:

GTK2 is used in Eclipse IDE (eclipse.org) to display it's source code editors
All tested versions of eclipse 3.2/3.3/3.4 old and new work fine with
gtk2-2.13.5-1 and earier.

2.13.6-1 and newer makes application hang when it os first going to show a source code editor.

At first glance this might seem like an Eclipse application bug, however this effects very anchient incarnations of eclipse as well as new ones. and is narrowed down to as recent as 5 versions back of gtk2.

Version-Release number of selected component (if applicable):
2.12.11-1 cant reproduce
2.13.5-1 cant reproduce
2.13.6-1 reproduces this
2.13.6-2 reproduces this
2.13.6-3 reproduces this

How reproducible:
Every time.
possible x86_64 is required.

Steps to Reproduce:
1. Install Eclipse (Fedora Eclispe is fine (any version)) yum install eclipse
2. Install 2.13.6-1 or later.
3. Start eclipse.
4. Create a new project.
5. Create a .java file in the project.
6. Try to open the java file.

Actual results:
The editor sits there blank waiting for gtk2 to tell it that the view pane (drawing?) is completed.

Expected results:
For the "Java File" view part to start

Additional info:

Since eclipse is waiting for the call to gtk2 to return it is possible to queue up more tasks in eclipse.. Like opening a properties dialog.. these dialogs do not depend on GTK2. Shut down eclipse from the File menu.. Eclipse will give up waiting for GTK2 and the forementioned queued windows will pop up.

Steps to workarround:
use 2.13.5-1 or earier

Comment 2 Matthias Clasen 2008-08-14 20:17:49 UTC

If you could attach with gdb to the editor when it gets stuck and generate a stacktrace, that might be helpful.

Comment 3 Douglas Miles 2008-08-15 08:45:58 UTC

Here is java's quick version of a stack trace "_gtk_enumerate_printers"

(I am having trouble getting gdb to give me anyhting usefull at the moment)

Comment 4 Andrew Overholt 2008-08-15 14:36:34 UTC

Douglas:  your stacktrace looks decent enough to me, but in case you wondered, [1] has details on how to produce one from Eclipse.

It looks like this may be this bug:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=215234

Upstream notes on how to work around this issue:

http://www.eclipse.org/swt/faq.php#printOnGTKHangs
-> eclipse -vmargs -Dorg.eclipse.swt.internal.gtk.disablePrinting

https://bugs.eclipse.org/bugs/show_bug.cgi?id=213487#c8

indicates that upstream Eclipse believes it to be a gtk bug but I can't find a reference to one.

Matthias:  are you aware of such a bug?  There are a few other interesting bits of information here:

Comment 5 Douglas Miles 2008-08-16 08:46:49 UTC

Andrew, thank you for the -Dorg.eclipse.swt.internal.gtk.disablePrinting.
It did workarround this!

Also of note: 
"gtk_enumerate_printers needs events to complete" 
http://bugzilla.gnome.org/show_bug.cgi?id=346903

In my case and (probably many others) my unix printing (cups etc) isn't configured corretly. And cups or smb is causing the blocking to gtk2.

Comment 6 Matthias Clasen 2008-08-16 19:37:51 UTC

FYI: I've reopened the upstream bug, and I think we can at least prevent gtk_enumerate_printers() from blocking if cups is not responding.

Comment 7 Matthias Clasen 2008-09-25 19:01:16 UTC

Should be fixed in rawhide
