- Update to 1.6.2
|
|
* Fixed `numpy` import in `toplevel.py`, this makes python-blosc usable without
|
|
numpy once again.
|

|
|
* Updated C-Blosc to 1.14.3
|
|

pickled arrays that were compressed with Python 2.x using Python 3.x. Thanks
|
|
to Simba Nyatsanga and Juan Maree.

|
|
|
- Update to version 1.5.1
|
|
* License updated from MIT to BSD.
|
|
* Updated to C-Blosc 1.11.3.
|
|
- Update to version 1.5.0
|
|
* Added a new `blosc.set_releasegil()` function that allows to
|
|
release/acquire the GIL at will. See PR #116.
|
|
Thanks to Robert McLeod.
|
|
* Updated to C-Blosc 1.11.2.
|
|
* Added tests that detect possible memory leaks.
|
|
Thanks to Robert McLeod.
|
|
- Update to version 1.4.4
|
|
* Updated to C-Blosc 1.11.1. Fixes #115.
|
|
- Update to version 1.4.3
|
|
* Internal C-Blosc sources updated to 1.11.0. Among other things, this
|
|
updates the internal Zstd codec to version 1.0.0 (i.e. it is
|
|
officially apt for production usage!).
|
|
- Update to version 1.4.1
|
|
* Internal C-Blosc sources updated to 1.10.1. This fixes an outstanding issue
|
|
with the clang compiler. For details, see:
|
|
https://github.com/Blosc/bloscpack/issues/50.
|
|
- Update to version 1.4.0
|
|
* Internal C-Blosc sources updated to 1.10.0.
|
|
* Benchmarks updated for a Skylake processor (Xeon E3-1245 v5 @
|
|
3.50GHz).
|
|
- Update to version 1.3.3
|
|
* Internal C-Blosc sources updated to 1.9.3.
|
|
* C-Blosc do not segfaults anymore, so -O1 flag on Linux is not the
|
|
default anymore.
|
|
* SSE2 and AVX2 are now auto-discovered so the internal C-Blosc will be
|
|
compiled with maximum optimization on processors supporting them.
|
|
- Update to version 1.3.2
|
|
* Fixed the version of the include C-Blosc library (should be 1.8.1 not
|
|
1.8.2.dev).
|
|
- Update to version 1.3.1
|
|
* Use the -O1 flag for compiling the included C-Blosc sources on Linux.
|
|
This represents slower performance, but fixes the nasty issue #110.
|
|
Also, it prints a warning for using an external C-Blosc library.
|
|
* Internal C-Blosc version bumped to 1.8.1 for better compatibility
|
|
with gcc 5.3.1 in forthcoming Ubuntu Xenial.
|
|
* Added a protection to avoid using BITSHUFLE with C-Blosc < 1.8.0.
|
|
* Restored old symbols for backward compatibility with pre 1.3.0:
|
|
BLOSC_VERSION_STRING
|
|
BLOSC_VERSION_DATE
|
|
BLOSC_MAX_BUFFERSIZE
|
|
BLOSC_MAX_THREADS
|
|
BLOSC_MAX_TYPESIZE
|
|
However, these are considered deprecated and should be replaced by
|
|
libraries using python-blosc by the ones without the BLOSC_ prefix.
|
|
- Update to version 1.3.0
|
|
* Internal C-Blosc version bumped to 1.8.0. As consequence, support for
|
|
BITSHUFFLE is here. For activating it, just pass `blosc.BITSHUFFLE`
|
|
to the `shuffle` parameter of compression functions.
|
|
* Added a new `as_bytearray=False` parameter to the `decompress()` function
|
|
so that a mutable bytearray will be returned instead of a bytes one
|
|
(inmutable). PR #107. Thanks to Joe Jevnik.
|
|
* The '__all__' variable has been removed from the module. I consider
|
|
this good practice to avoid things like "from blosc import *".
|
|
* For consistency, the next symbols have been renamed:
|
|
BLOSC_VERSION_STRING -> VERSION_STRING,
|
|
BLOSC_VERSION_DATE -> VERSION_DATE,
|
|
BLOSC_MAX_BUFFERSIZE -> MAX_BUFFERSIZE,
|
|
BLOSC_MAX_THREADS -> MAX_THREADS,
|
|
BLOSC_MAX_TYPESIZE -> MAX_TYPESIZE,
|
|
* The `typesize` parameter is set by default to 8 in compression
|
|
functions. This usually behaves well for 4-bytes typesizes too.
|
|
Nevertheless, it is advised to use the actual typesize.
|
|
* The maximum number of threads to use by default is set to 4 (less if
|
|
less cores are detected). Feel free to use more or less threads
|
|
depending on the resources you want to use for compression.
|
|
- Implement single-spec version.

|
|
|
|
- Update to version 1.2.8
|
|
* Updated to c-blosc v1.7.0. However, the new bitshuffle filter
|
|
has not been made public because recent reports indicate that
|
|
it seems too green for production.
|
|
* Support bytes-like objects that support the buffer interface
|
|
as input to compress and decompress. On Python 2.x this
|
|
includes unicode, on Python 3.x it doesn't. (#80 #94 @esc)
|
|
* Fix a memory leak in decompress. Added tests to catch memory
|
|
leaks. (#102 #103 #104 @sdvillal)
|
|
* Various miscellaneous fixes and improvements.

|
|
* Added wrapper for the expert function ``set_blocksize``.
|
|
(#72 @esc)
|
|
* Fix setup.py to allow compilation on posix architectures
|
|
without SSE2. (#70 @andreas-schwab)
|

Thu Jul 17 09:32:38 UTC 2014 - toddrme2178@gmail.com
|
|
|
|
- Update to 1.2.4
|
|
- Updated to c-blosc 1.4.0. This added support for non-Intel
|
|
architectures, most specially those not supporting unaligned access.
|

Thu May 8 12:14:34 UTC 2014 - toddrme2178@gmail.com
|
|
|
|
- Update to 1.2.3
|
|
- Updated to c-blosc 1.3.5. This removed a 'pointer from integer
|
|
without a cast' compiler warning due to a bad macro definition.
|
|
- Update to 1.2.2
|
|
- Updated to c-blosc 1.3.4. This fixed a false buffer overrun
|
|
condition. This bug made c-blosc (and hence python-blosc) to fail,
|
|
even if the failure was not real.
|
|
- Update to 1.2.1
|
|
- Updated to c-blosc 1.3.3.
|
|
- Added a new `cname2clib` map for programatically determine the library
|
|
associated to a compressor.
|
|
- New `get_clib(cbuffer)` that tells which compression library format
|
|
has been used to created the compressed `cbuffer`.
|
|
- Update to 1.2.0
|
|
- This release adds support for the multiple compressors added in Blosc
|
|
1.3 series.
|
|
- Added new `cname` parameter in compression functions like
|
|
`compress()`, `compress_ptr()` and `pack_array()`.
|
|
- Added a new utility function named `compressor_list()` that returns
|
|
the list of compressors supported in the Blosc build.
|
|
- Added 'bench/compress_ptr.py' for comparing times of the different
|
|
compressors in Blosc and NumPy.
|
|
- Update to 1.1.0
|
|
- Added new `compress_ptr` and `decompress_ptr` functions that allows to
|
|
compress and decompress from/to a data pointer. These are low level
|
|
calls and user must make sure that the pointer data area is safe.
|
|
- Since Blosc (the C library) already supports to be installed as an
|
|
standalone library (via cmake), it is also possible to link
|
|
python-blosc against a system Blosc library.
|
|
- The Python calls to Blosc are now thread-safe (another consequence of
|
|
recent Blosc library supporting this at C level).
|
|
- Many checks on types and ranges of values have been added. Most of
|
|
the calls will now complain when passed the wrong values.
|
|
- Docstrings are much improved. Also, Sphinx-based docs are available
|
|
now.
|
|
- Update to 1.0.6
|
|
- Fix compile error with msvc compilers. Thanks to Christoph Gohlke.
|
|
- Update to 1.0.5
|
|
- Upgraded to latest Blosc 1.1.4.
|
|
- Better handling of condition errors, and improved memory releasing in
|
|
case of errors (thanks to Valentin Haenel and Han Genuit).
|
|
- Better handling of types (should compile without warning now, at least
|
|
with GCC).
|
|
- Update to 1.0.4
|
|
- Optimized the amount of data copied during compression (using
|
|
_PyBytes_Resize() now instead of old PyBytes_FromStringAndSize()).
|
|
This leads to improvements in compression speed ranging from 1.2x for
|
|
highly compressible chunks up to 7x for mostly uncompressible data.
|
|
Thanks to Valentin Haenel for this nice contribution.
|
|
- Use external blosc library. The internal one builds a bad version
|
|
of zlib.
