[701ac713de] Made SizedReader faster by keeping explicit buffer indices. (user: spaskalev, tags: trunk)
22:32
[1717bfae3b] Use 0dev.org/ioutil.SizedWriter as an output buffer for pdc in both compress and decompress modes. (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)

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)

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)
2014-12-21
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)

[2be2ff6bf7] Added a function that reverses the bits in a byte. Coverage: 100.0% of statements. (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)
11:52
