------------------------------------------------------------------- Sun Sep 27 01:24:15 UTC 2015 - arun@gmx.de - update to version 3.2.2: * Fix AssertionError in Row.__init_loop. See gh-477. * Fix issues with Cython 0.23. See gh-481. * Only run tables.tests.test_basics.UnicodeFilename if the filesystem encoding is utf-8. Closes gh-485. * Fix missing missing PyErr_Clear. See gh-#486. * Fix the C type of some numpy attributes. See gh-494. * Cast selection indices to integer. See gh-496. * Fix indexesextension._keysort_string. Closes gh-497 and gh-498. - changes from version 3.2.1.1: * Fix permission on distributed source distribution ------------------------------------------------------------------- Mon Aug 10 00:38:11 UTC 2015 - arun@gmx.de - update to version 3.2.1: * Fix indexesextension._keysort. Fixes gh-455. Thanks to Andrew Lin. ------------------------------------------------------------------- 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. ------------------------------------------------------------------- Mon May 6 06:56:52 UTC 2013 - highwaystar.ru@gmail.com - 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. - for api changes check RELEASE_NOTES.txt
