Description:
greenify 0.4.1
greenify can make Python extension modules having network operations in C
code to be compatible with gevent.
greenify uses the Dynamic Function Redirecting technique same as ELF-Hook
to patch blocking network operations at runtime, without the need modify
the original modules.
Currently greenify only supports ELF format modules, and is tested on Linux.
Install from source
greenify module is installed using setuptools or pip:
python setup.py install
or:
pip install greenify
Usage
Active greenify before initiate environment:
import greenify
greenify.greenify()
Make sure the dynamic module(e.g. libmemcached) is patched before using:
assert greenify.patch_lib('/usr/lib/libmemcached.so')
Import and use the corresponding module, which is now gevent compatible.
Thread Safety
Once activated, the green C functions will, on potentially blocking operation,
pass control to gevent’s main event loop, which may switch to other ready
greenlet which is also in one of the green functions. So, make sure your C
code can handle this kind of execution pause and resume. A thread safe
program usually is ready for greenify, but remember that all the switches
happen in a single thread.
