| 18:52 | [38f8e62c81] Renamed MinReader to BlockReader. The later is now used by predictor's decompressor to simplify the code and deal away with the need for internal buffering. (user: spaskalev tags: trunk) | |
| 18:39 | [70896f73e9] Additional fixes and code simplification for MinReader (user: spaskalev tags: trunk) | |
| 14:27 | [4195e7817d] minReader fixes (user: spaskalev tags: trunk) | |
| 10:38 | [47b221d5b4] Added MinReader to ioutils, CC at 100% (user: spaskalev tags: trunk) | |
| 09:32 | [c62581c2a6] Removed the compressor alias type from predictor, use ioutil.WriterFunc (user: spaskalev tags: trunk) | |
| 08:15 | [2b049247ed] Removed the decompressor alias type from predictor, use ioutil.ReaderFunc (user: spaskalev tags: trunk) | |
| 07:52 | [2bcd5307ea] Added package ioutil with io.Writer and io.Reader function wrappers (user: spaskalev tags: trunk) | |

| 19:52 | [89bfe97384] Added documentation for the decompressor (user: spaskalev tags: trunk) | |
| 19:28 | [9dfd3cb1a2] Extracted the predictor's hash function as a method of the context struct. Minor changes to the decompressor's variables. (user: spaskalev tags: trunk) | |
| 17:15 | [27ecac81d3] Calculate the decompressed block length outside of the predictor loop (user: spaskalev tags: trunk) | |
| 16:41 | [6d10a1d28f] Integrate the decompressor2 branch into trunk now that it is faster. (user: spaskalev tags: trunk) | |
| 16:35 | [42ba1f458d] Closed-Leaf: Decompressor - try to fill as much as possible in the output buffer in a single pass. (user: spaskalev tags: decompressor2) | |
| 15:34 | [e9b80a705b] Fixed a nasty variable shadowing bug :) (user: spaskalev tags: decompressor2) | |
| 14:23 | [ae0940d072] Read available bytes and the end of the buffer and decompress in a singe pass (user: spaskalev tags: decompressor2) | |

| 23:26 | [52e14c83da] Closing the decompressor2 branch as this implementation is slower than the naive one. (user: spaskalev tags: decompressor2) | |
| 23:24 | [1f73d90f65] The decompressor now tries to fill in the whole output buffer in a single call. (user: spaskalev tags: trunk) | |
| 22:52 | [630530df49] Removed TODOs, renamed readCount->rc, wrapped->reader (user: spaskalev tags: trunk) | |
| 22:12 | [bd1368b81f] Check in the new decompressor implementation in a separate branch (user: spaskalev tags: decompressor2) | |
| 19:38 | [1a4bdf36e2] Added debug/pprof to ease basic cpu profiling (user: spaskalev tags: trunk) | |
| 17:23 | [7b74fd57f8] Fixed a rare case of losing data from the decompressor's internal result buffer. (user: spaskalev tags: trunk) | |
| 01:59 | [2be2ff6bf7] Added a function that reverses the bits in a byte. Coverage: 100.0% of statements. (user: spaskalev tags: trunk) | |

| 17:44 | [4f0d26907d] Buffer the input on decompressing, not the decompressor itself. This takes pdc -d < linux-3.18.1.tar.pdc > linux-3.18.1.tar down to 11 seconds from 13 minutes :) (user: spaskalev tags: trunk) | |
| 13:04 | [d516e7425d] Decompressor might loose part of the underlying buffer array by reslicing, fixed by copy (user: spaskalev tags: trunk) | |
| 11:52 | [723ffeb1fd] [predictor] Removed the buffer from the context struct, allocate the input slice buffer on creation with make. (user: spaskalev tags: trunk) | |
|
2014-12-19
| ||
| 21:54 | [c9f3a59cb6] Implemented commands/pdc using predictor. Made predictor's Compressor(...) return an io.Writer. (user: spaskalev tags: trunk) | |
|

| 23:29 | [0f4bc650d1] Removed err variable from compressor (user: spaskalev tags: trunk) | |
| 22:56 | [1847f77062] Reworked the compressor's buffering code, switched to table testing, add step testing for the compressor. Code coverage at 88.3% (user: spaskalev tags: trunk) | |
| 16:04 | [10013ae789] Removed goto from predictor's compressor, added more tests that invoke both compress/decompress (user: spaskalev tags: trunk) | |
| 04:03 | [b838653282] Fixed issues with both compressor and decompressor, added more tests (user: spaskalev tags: trunk) | |
