Bug 428838

Created attachment 291722 [details]
Patch to conduit spec file

Not sure this is the way to go (overriding %{_libdir} -- but otherwise if the
package is built on 64-bit machines it will install files in a different
location), so I have not patched the remaining shebang-scripts.

Would you be looking for a comaintainer, by any chance? This package looks
really interesting. Thanks.

I have a build that appears to work, but when I exit, I get:
python: Modules/gcmodule.c:276: visit_decref: Assertion `gc->gc.gc_refs != 0'
failed.
4a8de83b-5090-5b69-3b181b5a-3b235430 is dumped

Is that something you've seen in your build?

I'm reluctant to push any build, even to devel, while this is appearing.  Here
is my build for F-8: http://koji.fedoraproject.org/koji/taskinfo?taskID=366851

If you want to help with the package, request permissions in packagedb and I'll
set you up.

Mine has the assertion failure, but nothing is dumped:

python: Modules/gcmodule.c:276: visit_decref: Assertion `gc->gc.gc_refs != 0'
failed.

It might be better to wait for 0.4.0 then? That's the next stable version. I've
asked for permission in packagedb, thanks.

It looks to be a python bug since there is no native code in conduit.  If you
have time, install the python-debuginfo files and get a stacktrace.

Although this doesn't seems to be a conduit bug, I don't want to do any releases
on this until we have a better understanding of the problem.  It would cause a
bunch of bug reports to be filed.

Look like there have been released a 0.3.6 version.

http://www.conduit-project.org/wiki/0.3.6

If you guys need somebody to test the package, then just let med know

The build in comment #2 is 0.3.6 if you want to test drive it.  I'm assuming
you'll run into bug #429970 though which is currently blocking a new release.

Michel, if I understand your comment on bug #429970, you have tested the build
on rawhide and it does not crash?  If that is so, I'm going to push out a build
to rawhide to get wider testing/feedback.

I have not tested that particular build -- there does not seem to be any way to
download it. I'm still on my hacked-together 0.3.5, which also suffered from the
assertion failures before I upgraded to Rawhide.

But yes, push it and I'll give it a spin, thanks.

I have made a local build for F8 of 0.3.6 located here.

http://timlau.fedorapeople.org/files/test/conduit/

i get the
python: Modules/gcmodule.c:276: visit_decref: Assertion `gc->gc.gc_refs != 0'
failed.

on exit.
I look like the Flickr sync i working in 0.3.6 :)

Here is a rawhide build:

conduit-0.3.8-1.fc8 has been submitted as an update for Fedora 8

conduit-0.3.8-1.fc8 has been pushed to the Fedora 8 testing repository.  If problems still persist, please make note of it in this bug report.
 If you want to test the update, you can install it with 
 su -c 'yum --enablerepo=updates-testing update conduit'.  You can provide feedback for this update here: http://admin.fedoraproject.org/updates/F8/FEDORA-2008-1972

In testing, I'm getting a SEGFAULT:

Can someone confirm whether or not this is:
http://bugzilla.gnome.org/show_bug.cgi?id=509702

There is a test case in 
http://bugzilla.gnome.org/show_bug.cgi?id=509702#c28

If that causes the crash, then the bug is in your python gnomevfs bindings. (As
this has not been reported on anything but RH/Fedora and PLD Linux...)

Tried the test case you referenced on a fully updated F8:

[bjohnson@localhost ~]$ python
Python 2.5.1 (r251:54863, Oct 30 2007, 13:54:11) 
[GCC 4.1.2 20070925 (Red Hat 4.1.2-33)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> def _(*args, **kwargs):
...     pass
... 
>>> import gnomevfs
>>> t1 = gnomevfs.VolumeMonitor()
>>> t1.connect("volume-mounted",_)
1L
>>> t2 = gnomevfs.VolumeMonitor()
>>> t2.connect("volume-mounted",_)
2L
>>> 

Although, when I run it non-interactively:

[bjohnson@localhost tmp]$ python t
python: Modules/gcmodule.c:276: visit_decref: Assertion `gc->gc.gc_refs != 0'
failed.
Aborted
[bjohnson@localhost tmp]$

So it's a bug in the gnomevfs bindings rather than conduit. Most applications
don't hit this because they only have one volume monitor instance, but because
of our plugins we've ended up with 2 - thus triggering the bug.

The assertion hints that we are allocating something more than once, but only
freeing it once, so the reference count isn't 0 with python is closing.

It seems to only happen on F8/PLD Linux boxes so far, so i don't want to report
it directly GNOME bugzilla...

Is gnome-vfs2 the right component for this bug?

I have an update to conduit that disables the iPod and N800 modules for now
(enabling any of them trigger the gnome-vfs bug). Also updates the iPod
dependency to python-gpod, not libgpod, and fixes the Firefox detection to be
multilib-aware.
