| 20:53 | Renamed BlockReader to SizedReader, modified ioutil tests for 100% code coverage check-in: 11d1c50cd5 user: spaskalev tags: trunk | |
| 19:18 | Fixing ioutil tests to compile :) check-in: b0ff11dfcd user: spaskalev tags: trunk | |
| 18:52 | 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. check-in: 38f8e62c81 user: spaskalev tags: trunk | |
| 18:39 | Additional fixes and code simplification for MinReader check-in: 70896f73e9 user: spaskalev tags: trunk | |
| 14:27 | minReader fixes check-in: 4195e7817d user: spaskalev tags: trunk | |
| 10:38 | Added MinReader to ioutils, CC at 100% check-in: 47b221d5b4 user: spaskalev tags: trunk | |
| 09:32 | Removed the compressor alias type from predictor, use ioutil.WriterFunc check-in: c62581c2a6 user: spaskalev tags: trunk | |
| 08:15 | Removed the decompressor alias type from predictor, use ioutil.ReaderFunc check-in: 2b049247ed user: spaskalev tags: trunk | |
| 07:52 | Added package ioutil with io.Writer and io.Reader function wrappers check-in: 2bcd5307ea user: spaskalev tags: trunk | |

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

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

| 17:44 | 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 :) check-in: 4f0d26907d user: spaskalev tags: trunk | |
| 13:04 | Decompressor might loose part of the underlying buffer array by reslicing, fixed by copy check-in: d516e7425d user: spaskalev tags: trunk | |
| 11:52 | [predictor] Removed the buffer from the context struct, allocate the input slice buffer on creation with make. check-in: 723ffeb1fd user: spaskalev tags: trunk | |

| 21:54 | Implemented commands/pdc using predictor. Made predictor's Compressor(...) return an io.Writer. check-in: c9f3a59cb6 user: spaskalev tags: trunk | |

| 23:29 | Removed err variable from compressor check-in: 0f4bc650d1 user: spaskalev tags: trunk | |
| 22:56 | Reworked the compressor's buffering code, switched to table testing, add step testing for the compressor. Code coverage at 88.3% check-in: 1847f77062 user: spaskalev tags: trunk | |
| 16:04 | Removed goto from predictor's compressor, added more tests that invoke both compress/decompress check-in: 10013ae789 user: spaskalev tags: trunk | |
| 04:03 | Fixed issues with both compressor and decompressor, added more tests check-in: b838653282 user: spaskalev tags: trunk | |
| 01:55 | Added hamming weight lookup table for bytes in package bits. Added a PoC predictor decompressor implementation check-in: 60ca5b4b7b user: spaskalev tags: trunk | |

| 20:41 | Buffer stdout, use os.Args instead of flag check-in: 074a26f76b user: spaskalev tags: trunk | |
| 12:11 | Skip diagonals shorter than the current match check-in: e01b36769d user: spaskalev tags: trunk | |

| 00:16 | Initial implementation of a diff program and required libraries check-in: be5950faa4 user: spaskalev tags: trunk | |
| 00:04 | initial empty check-in check-in: 6c8d2e7c32 user: root tags: trunk | |
