| 01:25 | [2b1ed8e45e] Removed pdc's output buffer when decompressing as io.Copy uses a sufficiently-large buffer internally. (user: spaskalev, tags: trunk) | |
| 00:55 | [4dfcff962c] 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. (user: spaskalev, tags: trunk) | |
| 00:43 | [50507bd510] Extracted predictor's compressor and decompressor code into separate structs that embed Sized{Writer,Reader} (user: spaskalev, tags: trunk) | |

| 21:40 | [e1778aba98] 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. (user: spaskalev, tags: trunk) | |
| 19:07 | [c28a763d5e] Implemented ioutil/SizedWriter. CC at 100%. (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) | |

|
2014-12-20
| ||
| 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) | |
