Sebastian Messmer
bbdd8a548b Special case treatment for traversals until exactly the last leaf has to load the last leaf to grow it. Before this commit, we just always loaded the last traversed leaf and checked its size. Now we only do so if it's the right border leaf. This saves us loading some leaves. 2016-07-17 10:16:09 +02:00

Sebastian Messmer
eab7cb1df4 Implement BlockStore::overwrite(). This is the last step in ensuring that the write() call doen't have to load leaves if they're only overwritten anyhow. 2016-07-16 11:42:06 +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

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

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

fd5dd2c6e1 New way of handling block deletions: Set last-update-client-id to zero instead of increasing version number.

1a72d3c226 Deleting a block doesn't set the version number to MAX_UINT64, but just increases it by one. This makes sure, that if (in case of a synchronization conflict) the block is reintroduced by another client, this is accepted. 2016-06-26 22:15:52 -07:00
Sebastian Messmer
5534b56ce3 When increasing the version number, don't only look at the version number in the block, but also at the last version number given to it by the current client. Ensure, the new version number is higher than both. 2016-06-26 22:15:52 -07:00
Sebastian Messmer

40c64a879c Hide fuse quirks inside the Fuse class. 
fuse_main needs the program arguments as char ** instead of const char ** or (even better) vector<string>.
With this commit, we hide that inside the Fuse class. Everything outside handles these arguments as vector<string> and passes it as such to the Fuse class.

b9ac810414 - The version field in the config file is updated when the file system is opened with a newer CryFS version (i.e. it is migrated to the newer version). 
- We introduced a CreatedWithVersion field instead which gets the semantics the version field had before (i.e. which version of CryFS was the file system originally created with)
- Move VersionCompare to gitversion package
