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

d80b95514e Traversal doesn't load leaves, but returns the key. This way, the write() call can (after a future commit) write to full leaves without loading them beforehand. 2016-07-15 20:12:24 +02:00

0dbfdf3e2b When shrinking a tree, LeafTraverser takes care of decreasing tree depth, not DataTree anymore. This way, LeafTraverser is now responsible for increasing and decreasing depth as necessary. 2016-07-14 12:55:54 +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

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

fd5dd2c6e1 New way of handling block deletions: Set last-update-client-id to zero instead of increasing version number. This has the same effect (i.e. invalidates all known block versions) and it additionally allows for checking in a local list whether a block is deleted or not. 2016-06-26 22:15:52 -07:00

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

03f59b69da Since 0.9.3-alpha set the config value cryfs.blocksizeBytes wrongly to 32768 (but didn't use the value), we have to add a workaround. 2016-03-26 23:56:56 +08:00
Sebastian Messmer
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
