3.6 Mon Feb 7 17:37:31 CET 2011
- fixed hash calculation in C♯ version (Tiago Freitas Leal).
- unroll copy for small sizes, use memcpy for larger sizes,
greatly speeding up decompression in most cases.
- finally disable rep movsb - it's a big loss on modern intel cpus,
and only a small win on amd cpus.
- improve C++ compatibility of the code.
- slightly improve compressor speed.
- halved memory requirements for compressor on 64 bit architectures,
which can improve the speed quite a bit on older cpus.
3.5 Fri May 1 02:28:42 CEST 2009
- lzf_compress did sometimes write one octet past the given output
buffer (analyzed and nice testcase by Salvatore Sanfilippo).
3.4 Tue Sep 2 06:45:00 CEST 2008
- the fix from 3.3 introduced a compression bug, which is fixed in
this release (which explains the mysterious prerelease...). Thanks
once more to Clément Calmels.
3.3 Mon Aug 25 03:17:42 CEST 2008
- lzf_compress could access memory after the given input buffer
when outputting back references. reported with nice testcase
by Clément Calmels.
3.2 Fri May 9 18:52:23 CEST 2008
- include a workaround for failing POSIX and real-world compliance
on 64 bit windows (microsoft claims to support POSIX, but is far
from it). (bug found and analysed nicely by John Lilley).
3.1 Fri Nov 30 11:33:04 CET 2007
- IMPORTANT BUGFIX: a too long final literal run would corrupt data
in the encoder (this was introduced in 3.0 only, earlier versions
are safe).
3.0 Tue Nov 13 22:13:09 CET 2007
- switched to 2-clause bsd with "GPL v2 or any later version" option.
- speed up compression by ~10-15% in common cases
by some manual unrolling.
- import some compiler tricks from JSON::XS, for further speed-ups.
- tune hash functions depending on ULTRA_FAST or VERY_FAST settings.
- for typical binary data (e.g. /bin/bash, memory dumps,
canterbury corpus etc.), speed is now comparable to fastlz, but
with better compression ratio. with ULTRA_FAST, it's typically
3-15% faster than fastlz while still maintaining a similar ratio.
(amd64 and core 2 duo, ymmv). thanks a lot for the competition :)
- undo inline assembly in compressor, it is no longer helpful.
- no changes to the decompressor.
- use a HLOG of 16 by default now (formerly 15).
2.1 Fri Nov 2 13:34:42 CET 2007
- switched to a 2-clause bsd license with GPL exception.
- get rid of memcpy.
- tentatively use rep movsb on x86 and x86_64 (gcc only) for a
moderate speed improvement.
- applied patch by Kein-Hong Man to maske lzf.c compile under
the crippled mingw32 environment.
2.0 Fri Feb 16 23:11:18 CET 2007
- replaced lzf demo by industrial-strength lzf utility with behaviour
similar other compression utilities. Thanks for Stefan Traby for
rewriting it!
- fix state arg prototype.
1.7 Wed Sep 27 17:29:15 CEST 2006
- remove bogus "unlzf" patch.
note to self: never accept well-meant patches.
- make lzf more robust in presence of padding bytes or sudden eof.
1.6 Fri Jul 7 17:31:26 CEST 2006
- the lzf example utility will now uncompress if invoked
as "unlzf" (patch by Scott Feeney).
- add CHECK_INPUT option that adds more checks for input
data validity.
- help applications that do not pass in the correct length
(such as php) by returning either EINVAL or E2BIG.
- default HLOG size is now 15 (cpu caches have increased).
- documentation fixes.
1.51 Thu Apr 14 22:15:46 CEST 2005
- incorporated C♯ implementation of both the en- and decoder,
written by "Oren J. Maurice".
You can find it in the cs/ subdirectory.
- make FRST, NEXT IDX overridable if lzf_c.c is directly included
in the code.
1.5 Tue Mar 8 20:23:23 CET 2005
- incorporated improvements by Adam D. Moss,
which includes a new VERY_FAST mode which is
a bit slower than ULTRA_FAST but much better,
and enabled it as default.
1.401 Thu Mar 3 18:00:52 CET 2005
- use cstring in c++, not string.h.
- change of contact address.
1.4 Wed Dec 15 08:08:49 CET 2004
- very very slight tuning of the hashing function.
1.3 Thu Mar 25 15:41:17 CET 2004
- changed license of lzf core code to explicitly allow
relicensing under the GPLv2.
- added VPATH support as suggested by Björn Eriksson.
1.2 Mon Dec 29 13:47:28 CET 2003
- avoid spurious memory accesses after the to-be-compressed
memory region. originally reported by Michal Zalewski.
- flip LZF_STACK_ARG meaning (to be correct).
1.1 Tue Dec 23 05:48:32 CET 2003
- removed #warn directive, it's not worth the hassle.
- add LZF_STACK_ARG and AVOID_ERRNO configurations
for embedded systems.
- make it compile cleanly as c++.
- some small documentation and code fixes.
1.0 Sun Nov 17 12:37:37 CET 2002
- slightly better compression ratio, almost unmeasurably
slower.
- some documentation fixes.
0.4 Thu Jun 13 14:11:10 CEST 2002
- typoe fix.
- lzf demo program now properly decompresses small files.
- fix another 64 bit issue, found by Laurent Deniel.
0.3 Tue Jan 16 13:21:14 CET 2001
- fix silly beginners 32/64 bit mistake.
0.2 Thu Jan 4 05:56:42 CET 2001
- now totally independent of autoconfig, for
easy inclusion into other programs.
- much better fine-tuning, faster and better than 0.1.
0.1 2000
- initial release.
