Description Chris Withers 2011-08-22 05:28:10 EEST
Hi,

I'm using EPD 7.1 on Mac OS X, which ships with PySide 1.0.5 and IPython 0.11.

I'm using the IPython Qt Console a lot, but I'm finding that it crashes pretty
frequently and for no apparent reason. I initially raised this as an IPython
bug, but they suggested it was a PySide issue so filing here.

Here's an example from Apple's crash reporter:

Comment 1 Chris Withers 2011-08-22 22:09:25 EEST
Seems to be potentially related to the tool tips that pop up when you open a
bracket after a callable name in IPython, but this is just an observation...
Comment 2 Hugo Parente Lima 2011-08-23 20:21:03 EEST
We need a way to reproduce the crash, a stacktrace without debug symbols and
with no info about what Python code was executed give us absolutely no chance
to fix this bug.

Could you provide more info?
Comment 3 Chris Withers 2011-08-23 20:32:12 EEST
The "way to reproduce" for me is just to use the IPython console, typing,
moving mouse, etc.
Within an hour, I will have had at least one and likely two or 3 crashes. As I
said, the tooltips that appear when the ( of a function call is types seem to
be often, but not always, when the crashes happen.

I don't know how to get debug symbols working, I use EPD specifically so that I
don't have to fight the war of compiling things on Mac OS X.
Comment 4 Hugo Parente Lima 2011-08-23 20:40:52 EEST
Ok, let see what can we do... if you find a code snippet that crash more often,
feel free to attach it.
Comment 5 Chris Withers 2011-08-23 20:42:14 EEST
If it helps, I don't think I've ever seen a crash while actually running a
piece of code.
It's always been while just typing or moving the mouse over the IPython winder,
or dragging to select code to copy'n'paste.
Comment 6 Hugo Parente Lima 2011-08-23 21:00:54 EEST
And the code has some event handler?
Comment 7 Chris Withers 2011-08-25 21:32:51 EEST
"IPython winder" -> "IPython window"

Event handlers? No idea, I'd guess so, but I'm just using IPython, which I've
been told is using pyside for its Qt bindings...
Comment 8 renato filho 2011-08-31 00:00:50 EEST
this happen only when coding PySide code?

. Did you have write some code, or only import PySide?
. What kind of code have you write?
. Could you provide step by step how to reproduce the bug?
Comment 9 Chris Withers 2011-08-31 10:53:50 EEST
Please see https://github.com/ipython/ipython/issues/711 for reference.

I am not "coding pyside code".
I did not write code, other than in the IPython window.
I did not write code that imports PySide. I believe IPython 0.11 uses PySide
for its Qt bindings when using IPython's qtconsole.

I have experienced this code when just using IPython, the code I'm writing
doesn't seem to matter.
The problem appears to be with IPython's use of PySide on Mac OS X.

I have already provided a step-by-step guide to reproduce in my comments 3 and
5 above.
Comment 10 Min RK 2011-11-01 21:35:44 EET
I've isolated the issue.  It happens reliably when
`QtGui.qApp.topLevelAt(QtGui.QCursor.pos())` is called and the cursor is not
over a Qt element.

PyQt returns None in this case, while PySide segfaults every time.  I presume
this is just a NULL return that PySide doesn't check.

Simple Test case: https://gist.github.com/1331650

I was running PySide 1.0.6 on OSX, and could reproduce this issue 100% of the
time, but it seems to be fixed in 1.0.7, so you may be able to close the issue.
Comment 11 Hugo Parente Lima 2011-11-01 22:44:10 EET
PySide also returns None here and no crashes happens, but I'm not on Mac.

Linux
PySide from git HEAD of today.
Qt 4.7.4
Comment 12 Matti Airas 2012-03-08 16:57:18 EET
PySide is now a Qt-addon and uses Qt Project's JIRA tool for tracking bugs.
Please verify that the bug is still valid and re-submit it in the address
below:

Sorry for the inconvenience!
