Howdy,
this seems to be an important one, because of PySide's popularity.
While I'm not convinced that PySide is really bug-free... I have
to ask the Wing guys about how stable it is meanwhile.
What is your impression about the games that stackless plays
with the heaptype - do you see a way to get rid of this potential
source of hidden bugs?
How much of soft-switching would we loose if we stop using
this extra table at all. What alternatives do we have?
Since I'm working with pyside myself in a project, I get into the weird
situation
of not using Stackless, which is kind of ironic ;-)

The thing is, stackless has always been able to cope with PyTypeObjects coming
from external, because they do not have the Py_TPFLAGS_HAVE_STACKLESS_EXTENSION
flag on them and can thus be recognized. I think Anselm's patch just guarded
us against another of those issues.
But is that the issue that was causing the crashes with PySide? I thought
PySide were doing something more sinister, like copying static types and not
realizing it had to copy the trailing stackless extensions too. But I could be
wrong.
However, the remaining errors could be just another case where an external type
object's size is incorrectly used.

I thought we fixed that with Anselm's patch?

So, previously the issue with PySide was how it had a conflicting
redefinition of the PyTypeObject structure from stackless. I think.
Has it stopped doing that?

Hi,
Is anyone using PySide with Stackless and getting crashes?
Hi,
Okay, other than the crash on exit I emailed about above, I'm now
getting something more serious. I've tried reproducing it with
mainline Python 2.7.3 and failed. There's something broken with
Stackless, and it is directly related to when it is used with PySide.
In the case of the following stacktrace, the VM appears to get
confused or corrupt state. The sequence of activity is basically to
open a PySide window, open a file dialog, select a file, use the
given path to do file operations. Why it has suddenly started
repeatedly happening, I do not know. I've been doing what is now the
reproduction case for the last hour or so without a sign of it.
$ /c/Python27/python qtui.py
XXX lineno: 90, opcode: 0
Traceback (most recent call last):
File "qtui.py", line 192, in on_file_open_menu
line_count = run.UI_display_file(file_path)
...
hunk_id = file_info.uint32(f.read(4))
SystemError: unknown opcode
I'll try and find time to look into it, but this isn't how I want to
spend my time
:-)
Cheers,
Richard.
