dumblock

This package provides decorators that will try to acquire redis lock before calling decorated function.

Installation

pip install dumblock

Usage

Set DUMBLOCK_REDIS_URL in your django settings:

DUMBLOCK_REDIS_URL = "redis://localhost:6379"

lock_or_exit

Decorator. Before decorated function starts, try to acquire redis lock with specified key. If lock is acquired successfully, proceed executing the function. Otherwise, return immediately. The key argument can contain templated string, wich will be rendered with args and kwargs, passed to the function.

Example:

@lock_or_exit('lock_work_{}')
def workwork(x):
    pass

workwork(3)  # Will try to acquire redis lock 'lock_work_3'

lock_wait

Decorator. Before decorated function starts, try to acquire redis lock with specified key, waiting for waittime seconds if needed. If lock is acquired successfully, proceed executing the function. Otherwise, raise dumblock.TimeoutError. The key argument can contain templated string, wich will be rendered with args and kwargs, passed to the function.

Example:

@lock_wait('lock_work_{}', waittime=4)
def workwork(x):
    pass

workwork(3)  # Will try to acquire redis lock 'lock_work_3' for 4 seconds
