| 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 | |

| 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 | |
| 15:50 | Initial implementation of package mtf - a move-to-front transform. check-in: ad5c25d9ab 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 | |
