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
2014-12-23
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
2014-12-22
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
2014-12-21
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
2014-12-20
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
2014-12-19
21:54
Implemented commands/pdc using predictor. Made predictor's Compressor(...) return an io.Writer. check-in: c9f3a59cb6 user: spaskalev tags: trunk
2014-12-16
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
2014-12-15
21:22
Added diff.D struct; Added an RFC1978 Predictor compressor implementation and a test check-in: 67794bdf14 user: spaskalev tags: trunk
2014-12-14

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
