a (light) binding for blast/pklib (dclimplode)

dclimplode

a (light) binding for https://github.com/madler/zlib/blob/master/contrib/blast/blast.c and https://github.com/ladislav-zezula/StormLib/blob/master/src/pklib/implode.c

DCL stands for PKWARE(R) Data Compression Library.

o = dclimplode.compressobj()
s = o.compress(b'hello')+o.flush()
o = dclimplode.decompressobj()
o.decompress(s) == b'hello'

tested versions

• Python 2.7
• Python 3.9
• PyPy [2.7] 7.3.3
• PyPy [3.7] 7.3.5
  • For PyPy2, pip needs to be 20.1.x cf https://github.com/pypa/pip/issues/8653
  • PyPy needs to be 7.3.1+ cf https://github.com/pybind/pybind11/issues/2436
• Pyston [3.8] 2.3

special thanks

• https://github.com/JoshVarga/blast showed dclimplode compression by Ladislav Zezula (I knew dclimplode decompression in zlib for a long time though)
• unlike deflate64 infback9, making dclimplode blast resumable does not look possible (for me). instead I used threaded decoder. basic idea is from https://github.com/miurahr/pyppmd/pull/33#issuecomment-894676975 ('s linked commit f224a04).
