41146282ca Add test cases for tree traversal 2016-07-14 11:41:49 +02:00

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

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

a7f13ad7c1 When creating a file system, the user can choose whether to choose missing blocks as integrity violations. 2016-06-26 23:24:32 -07:00
Sebastian Messmer
2451a8c46f Add --missing-block-is-integrity-violation option. The option doesn't have an effect yet though. 2016-06-26 22:16:44 -07:00

be8dffb24d MyClientId is generated outside of CryDevice to give the CryConfigCreator access to it. 2016-06-26 22:15:52 -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

1c654305a8 In integrity violations, use individual messages saying which check exactly failed. 2016-06-26 22:15:52 -07:00

f066b45954 VersionCountingBlockStore::forEachBlock() has an integrity check checking that all expected blocks are still existing. 2016-06-26 22:15:52 -07:00

491b277cee In case of an integrity violation, tell the user how they can reset integrity data. 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
2284571127 Add test cases to KnownBlockVersionsTest 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
Sebastian Messmer
e02021ecdc Throw an IntegrityViolationError exception instead of just logging integrity violations. This makes sure the user notices. 2016-06-26 22:15:52 -07:00
