Sat May 9 22:26:55 UTC 2015 - arun@gmx.de
- specfile:
* updated copyright year
* removed modname
* updated source url to pypi
* add setuptools requirement
* updated version number requirement for numpy and numexpr
* README.txt -> README.rst
* added pttree bin
- update to version 3.2.0:
* The nrowsinbuf is better computed now for EArray/CArray having a
small chunkshape in the main dimension. Fixes #285.
* PyTables should be installable very friendly via pip, including
NumPy being installed automatically in the unlikely case it is not
yet installed in the system. Thanks to Andrea Bedini.
* setup.py has been largely simplified and now it requires
setuptools. Although we think this is a good step, please keep us
informed this is breaking some installation in a very bad manner.
* setup.py now is able to used pkg-config, if available, to locate
required libraries (hdf5, bzip2, etc.). The use of pkg-config can
be controlled via setup.py command line flags or via environment
variables. Please refer to the installation guide (in the User
Manual) for details. Closes gh-442.
* It is now possible to create a new node whose parent is a softlink
to another group (see gh-422). Thanks to Alistair Muldal.
* link.SoftLink objects no longer need to be explicitly
dereferenced. Methods and attributes of the linked object are now
automatically accessed when the user acts on a soft-link (see
gh-399). Thanks to Alistair Muldal.
* Now ptrepack recognizes hardlinks and replicates them in the
output (repacked) file. This saves disk space and makes repacked
files more conformal to the original one. Closes gh-380.
* New pttree script for printing HDF5 file contents as a pretty
ASCII tree (closes gh-400). Thanks to Alistair Muldal.
* The internal Blosc library has been downgraded to version
1.4.4. This is in order to still allow using multiple threads
inside Blosc, even on multithreaded applications (see gh-411,
gh-412, gh-437 and gh-448).
* The print_versions() function now also reports the version of
compression libraries used by Blosc.
* Now the setup.py tries to use the ‘-march=native’ C flag by
default. In falls back on ‘-msse2’ if ‘-march=native’ is not
supported by the compiler. Closes gh-379.
* Fixed a spurious unicode comparison warning (closes gh-372 and
gh-373).
* Improved handling of empty string attributes. In previous versions
of PyTables empty string were stored as scalar HDF5 attributes
having size 1 and value ‘0’ (an empty null terminated string). Now
empty string are stored as HDF5 attributes having zero size
* Added a new cookbook recipe and a couple of examples for simple
threading with PyTables.
* The redundant utilsextension.get_indices() function has been
eliminated (replaced by slice.indices()). Closes gh-195.
* Allow negative indices in point selection (closes gh-360)
* Index wasn’t being used if it claimed there were no
results. Closes gh-351 (see also gh-353)
* Atoms and Col types are no longer generated dynamically so now it
is easier for IDEs and static analysis tool to handle them (closes
gh-345)
* The keysort functions in idx-opt.c have been cythonised using
fused types. The perfomance is mostly unchanged, but the code is
much more simpler now. Thanks to Andrea Bedini.
* Small unit tests re-factoring:
+ print_versions() and tests.common.print_heavy() functions
moved to the tests.common module
+ always use print_versions() when test modules are called as scripts
+ use the unittest2 package in Python 2.6.x
+ removed internal machinery used to replicate unittest2 features
+ always use tests.common.PyTablesTestCase as base class for all test cases
+ code of the old tasts.common.cleanup() function has been moved to tests.common.PyTablesTestCase.tearDown() method
+ new implementation of tests.common.PyTablesTestCase.assertWarns() compatible with the one provided by the standard unittest module in Python >= 3.2
+ use tests.common.PyTablesTestCase.assertWarns() as context manager when appropriate
+ use the unittest.skipIf() decorator when appropriate
+ new :class:tests.comon.TestFileMixin: class
* Fixed compatibility problems with numpy 1.9 and 1.10-dev (closes
gh-362 and gh-366)
* Fixed compatibility with Cython >= 0.20 (closes gh-386 and gh-387)
* Fixed support for unicode node names in LRU cache (only Python 2
was affected). Closes gh-367 and gh-369.
* Fixed support for unicode node titles (only Python 2 was
affected). Closes gh-370 and gh-374.
* Fixed a bug that caused the silent truncation of unicode
attributes containing the ‘0’ character. Closes gh-371.
* Fixed descr_from_dtype() to work as expected with complex
types. Closes gh-381.
* Fixed the tests.test_basics.ThreadingTestCase test case. Closes
gh-359.
* Fix incomplete results when performing the same query twice and
exhausting the second iterator before the first. The first one
writes incomplete results to seqcache (gh-353)
* Fix false results potentially going to seqcache if
tableextension.Row.update() is used during iteration (see gh-353)
* Fix Column.create_csindex() when there’s NaNs
* Fixed handling of unicode file names on windows (closes gh-389)
* No longer not modify sys.argv at import time (closes gh-405)
* Fixed a performance issue on NFS (closes gh-402)
* Fixed a nasty problem affecting results of indexed queries. Closes
gh-319 and probably gh-419 too.
* Fixed another problem affecting results of indexed queries
too. Closes gh-441.
* Replaced "len(xrange(start, stop, step))" -> "len(xrange(0, stop -
start, step))" to fix issues with large row counts with Python
2.x. Fixes #447.
* Cython is not a hard dependency anymore (although developers will
need it so as to generated the C extension code).
* The number of threads used by default for numexpr and Blosc
operation that was set to the number of available cores have been
reduced to 2. This is a much more reasonable setting for not
creating too much overhead.

Thu May 8 11:15:34 UTC 2014 - toddrme2178@gmail.com
- New version 3.1.1
- Fixed a critical bug that caused an exception at import time.
The error was triggered when a bug in long-double detection is detected
in the HDF5 library (see :issue:`275`) and numpy_ does not expose
`float96` or `float128`. Closes :issue:`344`.
- The internal Blosc_ library has been updated to version 1.3.5.
This fixes a false buffer overrun condition that made c-blosc to fail,
even if the problem was not real.
- New version 3.1.0
- New features¶
- Now PyTables is able to save/restore the default value
of EnumAtom types.
- Implemented support for the H5FD_SPLIT driver.
- New quantization filter: the filter truncates floating point
data to a specified precision before writing to disk.
This can significantly improve the performance of compressors.
- Added new VLArray.get_row_size() method to VLArray for querying
the number of atoms of a VLArray row. Closes gh-24 and gh-315.
- The internal Blosc library has been updated to version 1.3.2.
All new features introduced in the Blosc 1.3.x series, and in
particular the ability to leverage different compressors within
Blosc (see the Blosc Release Notes), are now available in
PyTables via the blosc filter.
- Improvements¶
- The node caching mechanism has been completely redesigned to
be simpler and less dependent from specific behaviours of
the __del__ method. Now PyTables is compatible with the
forthcoming Python 3.4. Closes gh-306.
- PyTables no longer uses shared/cached file handlers.
This change somewhat improves support for concurrent reading
allowing the user to safely open the same file in different
threads for reading (requires HDF5 >= 1.8.7). More details
about this change can be found in the Backward incompatible
changes section. See also gh-130, gh-129 gh-292 and gh-216.
- PyTables is now able to detect and use external installations
of the Blosc library (closes gh-104). If Blosc is not found in
the system, and the user do not specify a custom installation
directory, then it is used an internal copy of the Blosc source
code.
- Automatically disable extended float support if a buggy version
of HDF5 is detected (see also Issues with H5T_NATIVE_LDOUBLE).
- Documented an unexpected behaviour with string literals in query
conditions on Python 3 (closes gh-265)
- The deprecated getopt module has been dropped in favour of
argparse in all command line utilities (close gh-251)
- Improved the installation section of the PyTables User’s Guide.
- instructions for installing PyTables via pip have been added.
- added a reference to the Anaconda, Canopy and Christoph
Gohlke suites (closes gh-291)
- Enabled Travis-CI builds for Python 3.3
- Tables.read_coordinates() now also works with boolean indices input.
- Improved compatibility with numpy >= 1.8 (see gh-259)
- The code of the benchmark programs (bench directory) has been updated.
- Fixed some warning related to non-unicode file names
(the Windows bytes API has been deprecated in Python 3.4)
- Bugs fixed¶
- Fixed detection of platforms supporting Blosc
- Fixed a crash that occurred when one attempts to write a numpy array
to an Atom (closes gh-209 and gh-296)
- Prevent creation of a table with no columns.
- Fixed a memory leak that occured when iterating over
CArray/EArray objects.
- Make NaN types sort to the end. Closes gh-282 and gh-313
- Fixed selection on float columns when NaNs are present.
- Fix computation of the buffer size for iterations on rows.
The buffers size was overestimated resulting in a MemoryError
in some cases. Closes gh-316. Thamks to bbudescu.
- Better check of file open mode. Closes gh-318.
- The Blosc filter now works correctly together with fletcher32. Closes gh-21.
- Close the file handle before trying to delete the corresponding file.
Fixes a test failure on Windows.
- Use integer division for computing indices (fixes some warning on Windows)
- Use external python3-blosc. The internal one builds a bad version
of zlib.

- initial python3 package based on 3.0.0
New features
------------
* Since this release PyTables provides full support to Python_ 3
(closes :issue`188`).
* The entire code base is now more compliant with coding style guidelines
describe in the PEP8_ (closes :issue:`103` and :issue:`224`).
See `API changes`_ for more details.
* Basic support for HDF5 drivers. Now it is possible to open/create an
HDF5 file using one of the SEC2, DIRECT, LOG, WINDOWS, STDIO or CORE
drivers. Users can also set the main driver parameters (closes
:issue:`166`).
Thanks to Michal Slonina.
* Basic support for in-memory image files. An HDF5 file can be set from or
copied into a memory buffer (thanks to Michal Slonina). This feature is
only available if PyTables is built against HDF5 1.8.9 or newer.
Closes :issue:`165` and :issue:`173`.
* New :meth:`File.get_filesize` method for retrieving the HDF5 file size.
* Implemented methods to get/set the user block size in a HDF5 file
(closes :issue:`123`)
* Improved support for PyInstaller_. Now it is easier to pack frozen
applications that use the PyTables package (closes: :issue:`177`).
Thanks to Stuart Mentzer and Christoph Gohlke.
* All read methods now have an optional *out* argument that allows to pass a
pre-allocated array to store data (closes :issue:`192`)
* Added support for the floating point data types with extended precision
(Float96, Float128, Complex192 and Complex256). This feature is only
available if numpy_ provides it as well.
Closes :issue:`51` and :issue:`214`. Many thanks to Andrea Bedini.
* New :program:`pt2to3` tool is provided to help users to port their
applications to the new API (see `API changes`_ section).
Improvements
------------
* Improved runtime checks on dynamic loading of libraries: meaningful error
messages are generated in case of failure.
Also, now PyTables no more alters the system PATH.
Closes :issue:`178` and :issue:`179` (thanks to Christoph Gohlke).
* Improved list of search paths for libraries as suggested by Nicholaus
Halecky (see :issue:`219`).
* Removed deprecated Cython_ include (.pxi) files. Contents of
:file:`convtypetables.pxi` have been moved in :file:`utilsextension.pyx`.
Closes :issue:`217`.
* The internal Blosc_ library has been upgraded to version 1.2.1.
* Pre-load the bzip2_ library on windows (closes :issue:`205`)
* The :meth:`File.get_node` method now accepts unicode paths
(closes :issue:`203`)
* Improved compatibility with Cython_ 0.19 (see :issue:`220` and
:issue:`221`)
* Improved compatibility with numexpr_ 2.1 (see also :issue:`199` and
:issue:`241`)
* Improved compatibility with development versions of numpy_
(see :issue:`193`)
* Packaging: since this release the standard tar-ball package no more includes
the PDF version of the "PyTables User Guide", so it is a little bit smaller
now. The complete and pre-build version of the documentation both in HTML
and PDF format is available on the file `download area`_ on SourceForge.net.
Closes: :issue:`172`.
* Now PyTables also uses `Travis-CI`_ as continuous integration service.
All branches and all pull requests are automatically tested with different
Python_ versions. Closes :issue:`212`.
Other changes
-------------
* PyTables now requires Python 2.6 or newer.
