- include a workaround for failing POSIX and real-world compliance |
4 |
|
|
on 64 bit windows (microsoft claims to support POSIX, but is far |
5 |
|
|
from it). (bug found and analysed nicely by John Lilley). |

in the encoder (this was introduced in 3.0 only, earlier versions |

root |
1.37 |
- switched to 2-clause bsd with "GPL v2 or any later version" option. |
14 |
root |
1.33 |
- speed up compression by ~10-15% in common cases |
15 |
|
|
by some manual unrolling. |
16 |
root |
1.37 |
- import some compiler tricks from JSON::XS, for further speed-ups. |
17 |
root |
1.33 |
- tune hash functions depending on ULTRA_FAST or VERY_FAST settings. |
18 |
|
|
- for typical binary data (e.g. /bin/bash, memory dumps, |
19 |
|
|
canterbury corpus etc.), speed is now comparable to fastlz, but |
20 |
|
|
with better compression ratio. with ULTRA_FAST, it's typically |
21 |
root |
1.34 |
3-15% faster than fastlz while still maintaining a similar ratio. |
22 |
|
|
(amd64 and core 2 duo, ymmv). thanks a lot for the competition :) |

- undo inline assembly in compressor, it is no longer helpful. |
24 |

- get rid of memcpy. |
30 |

- tentatively use rep movsb on x86 and x86_64 (gcc only) for a |
31 |

moderate speed improvement. |

- the lzf example utility will now uncompress if invoked |
48 |
|
|
as "unlzf" (patch by Scott Feeney). |
49 |
|
|
- add CHECK_INPUT option that adds more checks for input |
50 |
|
|
data validity. |
51 |

- help applications that do not pass in the correct length |
52 |
|

(such as php) by returning either EINVAL or E2BIG. |

a bit slower than ULTRA_FAST but much better, |
