Subject: [PATCH] Add Python 3.11 support
|
||||
|
||||
Link: https://github.com/unbit/uwsgi/pull/2453
|
||||
|
||||
* Use PyFrame_GetCode().
|
||||
* Add PyFrame_GetCode() for Python 3.8 and older.
|
||||
* Add UWSGI_PY311 macro: defined on Python 3.11 and newer.
|
||||
* struct uwsgi_python: "current_recursion_depth" becomes
|
||||
"current_recursion_remaining" and current_frame type becomes
|
||||
_PyCFrame** on Python 3.11.
|
||||
|
||||
Related Python 3.11 changes:
|
||||
|
||||
* https://docs.python.org/dev/whatsnew/3.11.html#id6
|
||||
* The PyFrameObject structure became opaque.
|
||||
* PyThreadState.frame (PyFrameObject) became PyThreadState.cframe
|
||||
(_PyCFrame) in Python 3.11.
|
||||
* PyThreadState: recursion_depth was replaced with
|
||||
recursion_remaining + recursion_limit.
