Problem Statement

• Improve lock unlock interfaces code written in utils by adding the duration of lock to be acquired by a thread.

Design

Added new parameter in lock as duration which will update for how much time a thread can acquire lock.
if a new thread wants to acquire the lock, test_lock() interface will check if the lock_end time which is calculated by duration is less than current time and if the new thread can acquire the lock or not.

Test Cases

from cortx.utils.conf_store import Conf
Conf.load('p0', 'consul://ssc-vm-g3-rhev4-3306.colo.seagate.com/conf8')
Conf.load('p1', 'consul://ssc-vm-g3-rhev4-3306.colo.seagate.com/conf8')
Conf.load('p2', 'consul://ssc-vm-g3-rhev4-3306.colo.seagate.com/conf8')

1. test "lock" interface

Conf.lock('p0', owner='p0', domain='prov', duration=30)
True

2. test "test_lock" interface

Conf.test_lock('p1', owner='p1', domain='prov')
False

3. test "unlock" interface

Conf.unlock('p0', owner='p0', domain='prov')
True

4. test "lock" repeat

Conf.lock('p0', owner='p0', domain='prov', duration=30)
True
Conf.lock('p0', owner='p0', domain='prov', duration=30)
True
Conf.lock('p1', owner='p1', domain='prov', duration=30)
False
Conf.lock('p0', owner='p0', domain='prov', duration=30)
True

5. lock at one thread and test “lock” from a different thread

Conf.lock('p0', owner='p0', domain='prov', duration=30)
True
Conf.lock('p1', owner='p1', domain='prov', duration=30)
False

6. lock at one thread and test “unlock” from a different thread

Conf.lock('p0', owner='p0', domain='prov', duration=30)
True
Conf.unlock('p1', owner='p1', domain='prov')
False

7. test “unlock” repeat

Conf.unlock('p1', owner='p1', domain='prov')
False
Conf.unlock('p1', owner='p1', domain='prov')
False
Conf.unlock('p1', owner='p1', domain='prov')
False

8. lock with two different domains

Conf.lock('p0', owner='p0', domain='prov', duration=30)
True
Conf.lock('p0', owner='p0', domain='hare', duration=30)
True

9. lock from one thread and test “unlock with force=true” from another thread

Conf.lock('p0', owner='p0', domain='prov', duration=30)
True
Conf.unlock('p1', owner='p1', domain='prov', force=True)
True

10. unlock from one thread and test “lock” from another

Conf.unlock('p1', owner='p1', domain='prov', force=True)
True
Conf.lock('p0', owner='p0', domain='prov', duration=30)
True
