e37d84a3d6 fspp::Dir, fspp::File and fspp::Symlink don't inherit from fspp::Node anymore. This allows file systems to return a generic fspp::Node instead of a concrete subclass when the operation doesn't need to know what type of node it is. 2017-01-21 19:16:35 +00:00

9e9369b9ed Performance optimization: When removing or shrinking a tree, we don't load/read leaves anymore. Loading inner nodes is enough to get all block IDs and then we can delete the leaves from their IDs without loading them. 2016-07-13 11:27:31 +02:00

3425760daf Implement migration for old filesystems that don't have parent pointers. 2016-06-27 20:03:44 -07:00
Sebastian Messmer
397de9372f Each blob stores a parent pointer (i.e. the ID of the directory that contains this blob). This stores the directory structure in a conflict-proof way and can be used to resolve such conflicts. 2016-06-27 18:22:13 -07:00

514dbcb6c7 ClientId is not loaded/generated inside of KnownBlockVersions, but in CryDevice. This way, CryDevice also has access to the ClientID. This is later needed to recognize whether we're in a single-client or in a multi-client setting. 2016-06-26 22:15:52 -07:00
Sebastian Messmer
839a511c4d When an integrity violation is detected, any further access to the file system is blocked. This ensures that the user notices the integrity violation. 2016-06-26 22:15:52 -07:00
Sebastian Messmer
c84a230afd VersionCountingBlockStore is initialized with a flag, saying whether missing blocks are integrity errors. This flag is meant to be activated in a single-client scenario to have this additional integrity check. 2016-06-26 22:15:52 -07:00
