synchronization - named reentrant/recursive lock (RLock) in Python -

-

the python multiprocessing module has class reentrant/recursive locks:

from multiprocessing import rlock  l = rlock() l.acquire() l.acquire() l.release() l.release()

this works great processes forked common parent process and, hence, can share same rlock object. however, situations independent processes (example: web server + cron job), 1 need named lock. unfortunately, rlock() not accept name argument lock. there solution allows this?

l = rlock('mylock') l.acquire() l.release()

check out oslo_concurrency.lockutils. has lock context manager , synchronized decorator, both of take name , other handy interprocess-friendly parameters.
