| 15:12 | Use a common fibonacci number source for each encoder and decoder. Dropped the two-bytes buffer from the encoder struct. check-in: f1a8d5baa9 user: spaskalev tags: trunk | |
| 14:11 | Initial implementation and test of fibonacci.Reader(io.Reader) io.Reader that decodes bytes encoded from fibonacci.Writer(..). CC at 97.5% check-in: 4b9f9bff39 user: spaskalev tags: trunk | |
| 06:34 | Fixed Decode's length return and added a test for it. Reduce encoder's buffer to 2 bytes. CC at 98.3% check-in: ea97951fcd user: spaskalev tags: trunk | |
| 05:30 | Added a proper test for fibonacci.Writer that writes 0-255, converts the resulting bits to a string and compares against the result of Numbers.Code for each value. check-in: c7c8d6445f user: spaskalev tags: trunk | |
| 04:58 | Added fibonacci.Writer(io.Writer) io.Writer that encodes bytes. check-in: 93fcb281a1 user: spaskalev tags: trunk | |

| 22:59 | Dropped the Nth method and return a populated slice by fibonacci.New(size). Changed all access to direct indexing. CC at 100% check-in: ffb139e305 user: spaskalev tags: trunk | |
| 15:01 | Minor opmitization to fibonacci's decoding. Changed plaindiff to show line numbers starting from 1. check-in: 9f5054e305 user: spaskalev tags: trunk | |
| 14:03 | Added encoding/fibonacci (cc: 100%) check-in: 7a1684ea05 user: spaskalev tags: trunk | |

| 18:06 | [mtf] Removed :to indices from copy(..) destinations. check-in: c07658474d user: spaskalev tags: trunk | |
| 17:19 | Integrate ioutil.ReadByte from the bpe branch into trunk. check-in: 00c4e0e448 user: spaskalev tags: trunk | |
| 17:16 | • Edit [7f9a25c94d]: Add propagating "hidden". artifact: 8ddd22d05d user: spaskalev | |

| 21:35 | Added 0dev.org/types, providing aliases that implement sort.Interface for [u]int{8|16|32|64} check-in: 129d90b4a8 user: spaskalev tags: trunk | |
| 16:02 | Initial implementation of commands/mtf (based on commands/pdc) check-in: e72b637df4 user: spaskalev tags: trunk | |

| 08:48 | Allocate the predictor's decompression buffer per Read call. check-in: f06f8cd058 user: spaskalev tags: trunk | |
| 01:25 | Removed pdc's output buffer when decompressing as io.Copy uses a sufficiently-large buffer internally. check-in: 2b1ed8e45e user: spaskalev tags: trunk | |
| 00:55 | Predictor's compressor and decompressor structures now implement io.Writer/io.Reader in order to deal away with function indirection but they do not follow the required semantics. Those are provided by the SizedWriter/SizedReader wrappers returned by the constructor functions. check-in: 4dfcff962c user: spaskalev tags: trunk | |
| 00:43 | Extracted predictor's compressor and decompressor code into separate structs that embed Sized{Writer,Reader} check-in: 50507bd510 user: spaskalev tags: trunk | |
| 00:26 | Extracted SizedWriter to a sizedWriter struct with a Write() method. check-in: 46da7a6ae9 user: spaskalev tags: trunk | |

| 23:58 | 0dev.org/ioutil/SizedReader is now as fast as bufio.Reader if not faster for a buffer of 4096 bytes. Switched pdc to use it for decompression buffering and removed profiling code from the former check-in: 2cec92909f user: spaskalev tags: trunk | |
| 23:45 | Extracted SizedReader to a sizedReader type with a Read() method. Closures seem to be slower in Go 1.4 and there is no real need for SizedReader to be a closure. check-in: b703c38e0b user: spaskalev tags: trunk | |
| 23:33 | Made SizedReader faster by keeping explicit buffer indices. check-in: 701ac713de user: spaskalev tags: trunk | |
| 22:32 | Use 0dev.org/ioutil.SizedWriter as an output buffer for pdc in both compress and decompress modes. check-in: 1717bfae3b user: spaskalev tags: trunk | |
| 21:40 | Fixed SizedWriter behavior so that it follows io.Writer's Write(...) contract. Added more tests for 100% CC on the ioutil package. Predictor's compressor now uses SizedWriter and no longer has to do any internal buffering. check-in: e1778aba98 user: spaskalev tags: trunk | |
| 19:07 | Implemented ioutil/SizedWriter. CC at 100%. check-in: c28a763d5e user: spaskalev tags: trunk | |
| 08:24 | Added an explicit copyright notice in the code. check-in: ffd1ab7b0c user: spaskalev tags: trunk | |

| 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 | |
| 13:38 | • Edit [52e14c83da]: Remove the "Closed" mark. Cancel "hidden". artifact: 2551e58fc8 user: spaskalev | |

| 23:29 | • Edit [52e14c83da]: Add propagating "hidden". artifact: aa1a7f0390 user: spaskalev | |
| 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 | |
