hello there,
I have written a small standalone Python web server in C using libev.
I want to run it within a Python thread to make it possible to share
memory easily.
Unfortunately it seems like the thread that runs the libev mainloop
blocks any other Python thread: Once the libev loop has been started,
code in other threads won't be executed any more. If I send a request
to the server -- so the libev thread leaves the libev loop code and
enters my web server C code -- other Python threads' code is executed.
Until the C code re-enters the libev code.
I tried threading priorities, but that didn't change anything.
Changing the backend doesn't change anything, either (I tried epoll and
select).
I debugged around a little bit and found out that the other Python
threads all stop some mystic `sem_wait`. Not that this is something to
worry about -- but could it be that something deadlocks there? Or is it
just libev that doesn't give the poor(ly implemented) Python interpreter
a chance of taking back control? ;-)
I'm glad about any suggestions on how to fix this stuff.
Thanks!
Jonas
PS: If you want code:
git clone git://github.com/jonashaag/bjoern
cd bjoern
make get-http-parser
make
python tests
