Revision history for Perl extension Data::BitStream.
0.08 16 Aug 2014
- Updates to documentation.
- Goldbach encoding almost 2x faster (sped up pair search).
0.07 1 Jan 2013
- Change from Mouse to Moo. Mouse has great performance, but the Perl
community is moving toward Moo/Moose and away from Any:Moose and
Mouse. In most cases Moo will be similar performance assuming the
Class::XSAccessor module is installed.
- Remove some Unicode characters that snuck into references.
- Much faster primes for big Goldbach codes. DBXS is still ~30x
faster overall, but almost all of that is the pair search.
- Add BER and Varint codes.
0.06 28 May 2012
- Make all tests numbered.
- Documentation additions (Pod Coverage testing).
- get_arice / put_arice modify the k parameter, just like XS code.
- Update Additive / Goldbach to reflect DBXS and MPFS changes.
0.05 17 May 2012
- Make a couple 64-bit tests work properly with the 'xs' module on
LLP64 systems.
- Add put_raw, from_raw uses it.
- String has custom to_raw and put_raw.
- Inline C for decorrelator / predictor in image compression example.
- Better behavior when doing bad reads.
- Unify a lot of error strings.
- Add generalized Fibonacci coding (order 2-16).
- Add additive and Goldbach G1/G2 codes from Fenwick's 2002 IEEE paper.
- Add comma codes (including ternary comma codes e.g. Fenwick 1996).
- Add block-based taboo codes (Pigeon 2001).
0.04 9 Nov 2011
- Fix late regression in one of the tests, unpack "W" -> "C".
- Minor test and documentation changes.
- Make most error strings consistent.
0.03 Mon Nov 7 06:00:00 2011
- More work on unit tests.
- Add BLVec class to use XS. Inefficient but it works (and even with
the silly setpos/setlen after every call, it's much faster than PP).
- Don't use Vec and BitVec implementations unless specifically asked.
- Lossless image codec example.
- Simple file support (read / write).
- Text methods (code_get, code_put, add_code)
- Performance.
- Clarify POD compression example slightly.
- More tests on 32-bit and big-endian machines.
0.02 Fri Sep 30 08:16:13 2011
- Create dist with tool instead of by hand. Uses version number.
- WordVec was setting the Vec variables.
