*** This bug is a duplicate of bug 935756 ***
https://bugs.launchpad.net/bugs/935756
** Description changed:
I've been experiencing this with our www.epoptes.org application, but I've
been able to reproduce the problem with
http://twistedmatrix.com/documents/current/core/examples/pbgtk2.py too.
I.e. when I run one of those apps from a console, and then close the
application window, the window does close, but my console prompt doesn't
return. Sometimes the app closes after 20-30 seconds, sometimes it just sits
there forever waiting. An strace tells me it's waiting at some poll() call.
The same programs run fine in previous versions of Ubuntu.
Also, if I put a `reactor.crash()` just before `reactor.stop()`, then those
programs terminate immediately.
+
+ == SRU (I know this bug is a duplicate, but we need to tie this SRU to
epoptes) ==
+ [rational]
+ A workaround for this bug was added to epoptes:
+ reactor.crash()
+
+ Now that the underlying bug was properly fixed, this should be removed
+ as it was just an ugly workaround that might lead to other problems.
+
+ [test case]
+ 1) Run epoptes from the console
+ 2) Close it
+
+ Check that the console returns immediately without errror.
+
+ [regression potential]
+ Just removing an hack, don't expect any regression.
+ Worst case scenario the twisted bug reappears and closing epoptes will hang
again, leaving an extra process running on the machine. As ubuntuone was also
affected by that bug, it's very unlikely it could reappear in the stable
release without us noticing.
