Windows/IOCP crashes about asyncoro

[alxchk]

After some testing I'm not sure about the reason of this issue. WSASend bla-bla only acquires with WinDbg, probably right in time of crash. Without WinDbg it just dies on recv or about it after some time.

gc.disable() doesn't fix the problem

I am not actually familiar with IOCP. The implementation is based on documentation of API (i.e., the only "experience" I have with IOCP is in implementing it for asyncoro). If you are familiar with it, please check/fix.

I didn't quite understand '_schedule' comment above. In the current master polling has been revamped and likely may affect how the error manifests.

Is it possible to use asyncoro's RCI and/or discoro instead of rpyc?

Well, my even worse. I will try to figure out the problem, but for windows I don't know how to monitor memory issues properly.

I tried asyncoro from pip

Unfortunately no, because main project is already written using rpyc.

I started thread in pywin32 tracker (https://sourceforge.net/p/pywin32/bugs/744/), maybe somebody knows what to do

[pgiri]

Please post here if there is any useful info regarding this. I am hoping to release asyncoro 4.4.0 tomorrow, unless there are any show stoppers (I have a few commits pending). Please test again with the release and see if you can reproduce this issue.

Same story with current master. Python interpreter dies in GC. I placed minimal working part of failed program here - https://gist.github.com/alxchk/482055c284dc3289f1b61b843908c2af
I have next setup with 100% reproduce:

1. Windows 7/10
2. rpyc_classic on Linux host
3. asyncoroproxy-test.py runned on Windows host
4. Firefox + Socks5 proxy walks via asyncoroproxy from Windows host
5. Open several sites simultaneously (and youtube among them)

Can you try asyncoro without IOCP? If you comment import pywintypes around line 920, or add raise Exception('') in that block, asyncoro will use select poller instead of IOCP. select is not efficient, but will narrow down problem.

You can also try Python 3.5 / 3.6 with 32 or 64 bit versions to find which setup is causing this.

With select I cant get crash, but it sooooo sloooow. I'd better rewrite stuff with pyuv instead of using this backend :)

I can't check it with python3 right now - looks like a lot of stuff should be fixed to be compatible with python3 in my script
