ijuma committed faa7dc76:

Remove unnecessary cast from byte to int.
ijuma committed f96f18dd:

Reformat files in compress.lzf to use the formatting standards used by Voldemort.
ijuma committed a345e2cd:

Remove dependency on h2-lzf.jar as we now include a LZF implementation in the source code.
ijuma committed e645a9fb:

Change LzfCompressionStrategy to use LZFEncoder and LZFDecoder.
ijuma committed bfa206a2:

Move LZF files to the right folder.
cowtowncoder committed 564d9d78:

Refactoring: moved lzf codec stuff in voldemort.store.compress.lzf
cowtowncoder committed 01cd4ff0:

Added license information (and related)
cowtowncoder committed b57cb9fa:

Fixed 2 remaining bugs: now passes large collection of documents without hitch
cowtowncoder committed 188e7961:

Added a unit test (pointed out one bug that's fixed; also, seems like there is one rarer one to fix)
cowtowncoder committed 16f00dd2:

Last part of refactoring.
cowtowncoder committed edc1bd44:

Additional refactoring.
cowtowncoder committed 32306a57:

Refactoring
cowtowncoder committed c9487e66:

Added compressor, seems to work for both directions. Note: compression results vary bit from c version due to different hash method, block sizes
cowtowncoder committed 44a6f90e:

First changes: added simple command-line tool (LZF.java) to check compress/decompress; created block codec (currently just implements decompress). But decompress code now uses "official" format, and works (as per brief testing, can correctly decompress lzf command line tool compressed files). And block codec is more efficient than streaming, for specific use case of V (as far as I can see).
ijuma committed cfac750e:

Import from SVN r2110.
