wsgidav.lock_storage.LockStorageDict

class wsgidav.lock_storage.LockStorageDict

Bases: object

An in-memory lock manager storage implementation using a dictionary.

R/W access is guarded by a thread.lock object.

Also, to make it work with a Shelve dictionary, modifying dictionary members is done by re-assignment and we call a _flush() method.

This is obviously not persistent, but should be enough in some cases. For a persistent implementation, see lock_manager.LockStorageShelve().

Notes

expire is stored as expiration date in seconds since epoch (not in seconds until expiration).

The dictionary is built like:

  { 'URL2TOKEN:/temp/litmus/lockme': ['opaquelocktoken:0x1d7b86...',
                                      'opaquelocktoken:0xd7d4c0...'],
    'opaquelocktoken:0x1d7b86...': { 'depth': '0',
                                     'owner': "<?xml version='1.0' encoding='UTF-8'?>\n<owner xmlns="DAV:">litmus test suite</owner>\n",
