Howdy,
today I found the final solution. Yay !-)
Very few lines of code, and binary compatible with CPython and Stackless.
That means you need not compile different versions if you switch to
Stackless.
This was the end of a long journey, until I realized:
- PySide does not directly use any structure that stackless changes.
- the only problem is that PySide wants to extend PyType_Type, but stackless
wants to do the same.
Solution:
- turn stackless off in PySide, by defining STACKLESS_OFF
- add the needed padding to SbkObjectType
By definition, STACKLESS_OFF has the effect of producing vanilla CPython,
so it is not even needed to test more than one version. It _is_ already
a plain CPython extension, and if it runs on stackless, it also runs on
CPython.
End of a long journey...
... and I should better remember solutions which were prepared since a
decade.
Well, this use case of STACKLESS_OFF was in fact not known before.
cheers - Chris
