wsgidav.lock_manager

Description

Implements the LockManager object that provides the locking functionality.

The LockManager requires a LockStorage object to implement persistence. Two alternative lock storage classes are defined in the lock_storage module:

• wsgidav.lock_storage.LockStorageDict
• wsgidav.lock_storage.LockStorageShelve

The lock data model is a dictionary with these fields:

root:

Resource URL.

principal:

Name of the authenticated user that created the lock.

type:

Must be ‘write’.

scope:

Must be ‘shared’ or ‘exclusive’.

depth:

Must be ‘0’ or ‘infinity’.

owner:

String identifying the owner.

timeout:

Seconds remaining until lock expiration. This value is passed to create() and refresh()

expire:

Converted timeout for persistence: expire = time() + timeout.

token:

Automatically generated unique token.
