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.
