[issue43007] set_wakeup_fd() only works in main thread

2021-11-20 Thread MeneMeneTekel

Finally... it works for me - I migrated to

 - Windows Server 2019 Datacenter
 - WinPython 3.9.5
 - Apache24 AH
 - Django 3.2.9
 - mod_wsgi-4.9.0-cp39-cp39-win_amd64

Whoever made that it works again thanks a lot ;-)

[issue43007] set_wakeup_fd() only works in main thread

2021-06-04 Thread MeneMeneTekel

Update: I just tried it again with 
 - Windows 10 Pro, 21H1
 - WinPython 3.9.4
 - Apache24
 - Django 3.2.4
 - mod_wsgi-4.8.0-cp39-cp39-win_amd64

Actually, there is no change, it got even worse. i.e. this wake up situation 
occurs more often. 

Remember: Changing WinPython 3.9.4 to WinPython 3.7.7 with 
mod_wsgi-4.7.1-cp37-cp37m-win_amd64 and all works fine!

Perhaps it's useful to have a stack trace? Here we are:

[issue43007] set_wakeup_fd() only works in main thread

2021-01-23 Thread MeneMeneTekel 


New submission from MeneMeneTekel :

This problem is marked as solved in issue38563, BUT the solution refers to some 
signal issues being solved - I'm using Python 3.8.7 on windows 10, where a 
signal solution may not work. I.e. my django (vers. 3.1.5) website crashes 
every second call with the message:

  File 
"C:\Winpython\WPy64-3870\python-3.8.7.amd64\lib\asyncio\proactor_events.py", 
line 632, in __init__
signal.set_wakeup_fd(self._csock.fileno())
ValueError: set_wakeup_fd only works in main thread
