This library was created in order to ease the synchronization of several processes using shared resources, like a caching directory or a SQLite database. All of them can use the resources, but only one should update them.
The library is being used in several INB projects.
import datetime
import os
import time
from RWFileLock import RWFileLock
lock = RWFileLock("/tmp/rwfilelock.lock")
with lock.shared_lock():
print(
f"[{datetime.datetime.now().isoformat()}] Got shlock {os.getpid()}"
)
time.sleep(7)
print(
f"[{datetime.datetime.now().isoformat()}] Releasing shlock {os.getpid()}"
)
