distlock-client 0.1.1

安装

pip install distlock-client

用法

1. 使用锁api。

from distlock_client import Lock
from distlock_client import get_app_unique_name
from .services import do_something

def view01(request):
    lockName = "view01_lock"
    appid = get_app_unique_name()
    server = "http://127.0.0.1/"
    lock = Lock(appid, server)

    locked = lock.safe_acquire(lockName, 60)
    if locked:
        try:
            do_something()
        finally:
            lock.safe_release(lockName)

1. 与语句一起使用。

from distlock_client import Lock
from distlock_client import distlock
from distlock_client import get_app_unique_name
from .services import do_something

def view01(request):
    lockName = "view01_lock"
    appid = get_app_unique_name()
    server = "http://127.0.0.1/"
    lock = Lock(appid, server)
    with distlock(lock, lockName) as locked:
        if locked:
            do_something()
