------------------------------------------------------------------- Mon Aug 10 00:30:34 UTC 2015 - arun@gmx.de - update to version 0.23: * Features added + PEP 492 (async/await) was implemented. See https://www.python.org/dev/peps/pep-0492/ + PEP 448 (Additional Unpacking Generalizations) was implemented. See https://www.python.org/dev/peps/pep-0448/ + Support for coverage.py 4.0+ can be enabled by adding the plugin "Cython.Coverage" to the ".coveragerc" config file. + Annotated HTML source pages can integrate (XML) coverage reports. + Tracing is supported in nogil functions/sections and module init code. + When generators are used in a Cython module and the module imports the modules "inspect" and/or "asyncio", Cython enables interoperability by patching these modules during the import to recognise Cython's internal generator and coroutine types. This can be disabled by C compiling the module with "-D CYTHON_PATCH_ASYNCIO=0" or "-D CYTHON_PATCH_INSPECT=0" + When generators or coroutines are used in a Cython module, their types are registered with the Generator and Coroutine ABCs in the collections or collections.abc stdlib module at import time to enable interoperability with code that needs to detect and process Python generators/coroutines. These ABCs were added in CPython 3.5 and are available for older Python versions through the backports_abc module on PyPI. See https://bugs.python.org/issue24018 + Adding/subtracting/dividing/modulus and equality comparisons with constant Python floats and small integers are faster. + Binary and/or/xor/rshift operations with small constant Python integers are faster. + When called on generator expressions, the builtins all(), any(), dict(), list(), set(), sorted() and unicode.join() avoid the generator iteration overhead by inlining a part of their functionality into the for-loop. + Keyword argument dicts are no longer copied on function entry when they are not being used or only passed through to other function calls (e.g. in wrapper functions). + The PyTypeObject declaration in cpython.object was extended. + The builtin type type is now declared as PyTypeObject in source, allowing for extern functions taking type parameters to have the correct C signatures. Note that this might break code that uses type just for passing around Python types in typed variables. Removing the type declaration provides a backwards compatible fix. + wraparound() and boundscheck() are available as no-ops in pure Python mode. + Const iterators were added to the provided C++ STL declarations. + Smart pointers were added to the provided C++ STL declarations. Patch by Daniel Filonik. + NULL is allowed as default argument when embedding signatures. This fixes ticket 843. + When compiling with --embed, the internal module name is changed to __main__ to allow arbitrary program names, including those that would be invalid for modules. Note that this prevents reuse of the generated C code as an importable module. + External C++ classes that overload the assignment operator can be used. Patch by Ian Henriksen. + Support operator bool() for C++ classes so they can be used in if statements. * Bugs fixed + Calling "yield from" from Python on a Cython generator that returned a value triggered a crash in CPython. This is now being worked around. See https://bugs.python.org/issue23996 + Language level 3 did not enable true division (a.k.a. float division) for integer operands. + Functions with fused argument types that included a generic 'object' fallback could end up using that fallback also for other explicitly listed object types. + Relative cimports could accidentally fall back to trying an absolute cimport on failure. + The result of calling a C struct constructor no longer requires an intermediate assignment when coercing to a Python dict. + C++ exception declarations with mapping functions could fail to compile when pre-declared in .pxd files. + cpdef void methods are now permitted. + abs(cint) could fail to compile in MSVC and used sub-optimal code in C++. Patch by David Vierra, original patch by Michael Enßlin. + Buffer index calculations using index variables with small C integer types could overflow for large buffer sizes. Original patch by David Vierra. + C unions use a saner way to coerce from and to Python dicts. + When compiling a module foo.pyx, the directories in sys.path are no longer searched when looking for foo.pxd. Patch by Jeroen Demeyer. + Memory leaks in the embedding main function were fixed. Original patch by Michael Enßlin. + Some complex Python expressions could fail to compile inside of finally clauses. + Unprefixed 'str' literals were not supported as C varargs arguments. + Fixed type errors in conversion enum types to/from Python. Note that this imposes stricter correctness requirements on enum declarations. * Other changes + Changed mangling scheme in header files generated by cdef api declarations. + Installation under CPython 3.3+ no longer requires a pass of the 2to3 tool. This also makes it possible to run Cython in Python 3.3+ from a source checkout without installing it first. Patch by Petr Viktorin. + jedi-typer.py (in Tools/) was extended and renamed to jedityper.py (to make it importable) and now works with and requires Jedi 0.9. Patch by Tzer-jen Wei. ------------------------------------------------------------------- Wed Jul 29 16:09:38 UTC 2015 - toddrme2178@gmail.com - Enable tests except on SLES 12 and openSUSE 13.2. ------------------------------------------------------------------- Wed Jul 29 11:47:46 UTC 2015 - toddrme2178@gmail.com - Remove unneeded numpy dependency to avoid dependency loop. ------------------------------------------------------------------- Tue Jul 21 07:47:31 UTC 2015 - coolo@suse.com - create dummy alternative to avoid 13.1's post-build-check bug ------------------------------------------------------------------- Tue Jul 21 04:04:43 UTC 2015 - arun@gmx.de - specfile: * fixing update_alternatives ------------------------------------------------------------------- Sun Jul 19 15:35:48 UTC 2015 - arun@gmx.de - specfile: (adapted from 2.7 version) * updated use of update_alternatives * added dependencies needed for test gcc-c++, numpy, numpy-devel * added dependency xml * (tried running tests, but for some distributions one test still failed, so didn't enable the tests) ------------------------------------------------------------------- Sun Jun 21 02:42:59 UTC 2015 - arun@gmx.de - update to version 0.22.1: * Crash when returning values on generator termination. * In some cases, exceptions raised during internal isinstance() checks were not propagated. * Runtime reported file paths of source files (e.g for profiling and tracing) are now relative to the build root directory instead of the main source file. * Tracing exception handling code could enter the trace function with an active exception set. * The internal generator function type was not shared across modules. * Comparisons of (inferred) ctuples failed to compile. * Closures inside of cdef functions returning void failed to compile. * Using const C++ references in intermediate parts of longer expressions could fail to compile. * C++ exception declarations with mapping functions could fail to compile when pre-declared in .pxd files. * C++ compilation could fail with an ambiguity error in recent MacOS-X Xcode versions. * C compilation could fail in pypy3. * Fixed a memory leak in the compiler when compiling multiple modules. * When compiling multiple modules, external library dependencies could leak into later compiler runs. Fix by Jeroen Demeyer. This fixes ticket 845. ------------------------------------------------------------------- Sat Feb 14 16:33:14 UTC 2015 - arun@gmx.de - specfile: * Cython->cython in tar ball name on pypi * fix update alternatives - update to version 0.22: * C functions can coerce to Python functions, which allows passing them around as callable objects. * C arrays can be assigned by value and auto-coerce from Python iterables and to Python lists (and tuples). * Extern C functions can now be declared as cpdef to export them to the module's Python namespace. Extern C functions in pxd files export their values to their own module, iff it exists. * Anonymous C tuple types can be declared as (ctype1, ctype2, ...). * PEP 479: turn accidental StopIteration exceptions that exit generators into a RuntimeError, activated with future import "generator_stop". See http://legacy.python.org/dev/peps/pep-0479/ * Looping over reversed(range()) is optimised in the same way as range(). Patch by Favian Contreras. * Mismatching 'except' declarations on signatures in .pxd and .pyx files failed to produce a compile error. * Failure to find any files for the path pattern(s) passed into cythonize() is now an error to more easily detect accidental typos. * The logaddexp family of functions in numpy.math now has correct declarations. * In Py2.6/7 and Py3.2, simple Cython memory views could accidentally be interpreted as non-contiguous by CPython, which could trigger a CPython bug when copying data from them, thus leading to data corruption. See CPython issues 12834 and 23349. * Preliminary support for defining the Cython language with a formal grammar. To try parsing your files against this grammar, use the --formal_grammar directive. Experimental. * _ is no longer considered a cacheable builtin as it could interfere with gettext. * Cythonize-computed metadata now cached in the generated C files. * Several corrections and extensions in numpy, cpython, and libcpp pxd files. ------------------------------------------------------------------- Thu Jan 8 12:24:06 UTC 2015 - dimstar@opensuse.org - Fix usage of update-alternatives. ------------------------------------------------------------------- Wed Dec 31 20:00:38 UTC 2014 - arun@gmx.de - specfile: add python3 again (complains about missing xml package otherwise) - update to version 0.21.2: * Crash when assigning a C value to both a Python and C target at the same time. * Automatic coercion from C++ strings to "str" generated incomplete code that failed to compile. * Declaring a constructor in a C++ child class erroneously required a default constructor declaration in the super class. * "resize_smart()" in "cpython.array" was broken. * Functions in "libcpp.cast" are now declared as "nogil". * Some missing C-API declarations were added. * Py3 main code in embedding program code was lacking casts. * Exception related to distutils "Distribution" class type in pyximport under latest CPython 2.7 and 3.4 releases when setuptools is being imported later. ------------------------------------------------------------------- Thu Dec 18 10:45:11 UTC 2014 - p.drouand@gmail.com - Remove make dependencies on python3-2to3 and python3, python3-devel is sufficient - Do not explicitely require python3, let RPM handle it ------------------------------------------------------------------- Wed Dec 17 09:52:48 UTC 2014 - p.drouand@gmail.com - Fix cygdb name typo in file list ------------------------------------------------------------------- Tue Dec 9 16:02:19 UTC 2014 - toddrme2178@gmail.com - Improve update-alternatives. ------------------------------------------------------------------- Sat Dec 6 00:00:33 UTC 2014 - arun@gmx.de - specfile: removed Cython-fix-version-detection.patch (got fixed upstream) - update to version 0.21.1: * Features added - New cythonize option -a to generate the annotated HTML source view. - Missing C-API declarations in cpython.unicode were added. - Passing language='c++' into cythonize() globally enables C++ mode for all modules that were not passed as Extension objects (i.e. only source files and file patterns). - Py_hash_t is a known type (used in CPython for hash values). - PySlice_*() C-API functions are available from the cpython.slice module. - Allow arrays of C++ classes. * Bugs fixed - Reference leak for non-simple Python expressions in boolean and/or expressions. - To fix a name collision and to reflect availability on host platforms, standard C declarations [ clock(), time(), struct tm and tm* functions ] were moved from posix/time.pxd to a new libc/time.pxd. Patch by Charles Blake. - Rerunning unmodified modules in IPython's cython support failed. Patch by Matthias Bussonier. - Casting C++ std::string to Python byte strings failed when auto-decoding was enabled. - Fatal exceptions in global module init code could lead to crashes if the already created module was used later on (e.g. through a stale reference in sys.modules or elsewhere). - cythonize.py script was not installed on MS-Windows. * Other changes - Compilation no longer fails hard when unknown compilation options are passed. Instead, it raises a warning and ignores them (as it did silently before 0.21). This will be changed back to an error in a future release. ------------------------------------------------------------------- Sun Nov 09 23:12:00 UTC 2014 - Led <ledest@gmail.com> - fix bashisms in pre script ------------------------------------------------------------------- Fri Sep 12 10:52:18 UTC 2014 - toddrme2178@gmail.com - Add Cython-fix-version-detection.patch This is a patch from upstream that restores version information whose removal is preventing several packages from correctly detecting Cython's presence. It is already merged upstream and so should be in the next release. Note that despite what upstream says, python-tables/python3-tables is NOT the only package affected by this, which is why the patch is going here instead of python-tables/python3-tables. python-bcolz/python3-bcolz is an example of another package affected. ------------------------------------------------------------------- Thu Sep 11 09:30:20 UTC 2014 - toddrme2178@gmail.com - Update to 0.21 (2014-09-10) * Features added * C (cdef) functions allow inner Python functions. * Enums can now be declared as cpdef to export their values to the module's Python namespace. Cpdef enums in pxd files export their values to their own module, iff it exists. * Allow @staticmethod decorator to declare static cdef methods. This is especially useful for declaring "constructors" for cdef classes that can take non-Python arguments. * Taking a ``char*`` from a temporary Python string object is safer in more cases and can be done inside of non-trivial expressions, including arguments of a function call. A compile time error is raised only when such a pointer is assigned to a variable and would thus exceed the lifetime of the string itself. * Generators have new properties ``__name__`` and ``__qualname__`` that provide the plain/qualified name of the generator function (following CPython 3.5). See http://bugs.python.org/issue21205 * The ``inline`` function modifier is available as a decorator ``@cython.inline`` in pure mode. * When cygdb is run in a virtualenv, it enables the same virtualenv inside of the debugger. Patch by Marc Abramowitz. * PEP 465: dedicated infix operator for matrix multiplication (A @ B). * HTML output of annotated code uses Pygments for code highlighting and generally received a major overhaul by Matthias Bussonier. * IPython magic support is now available directly from Cython with the command "%load_ext cython". Cython code can directly be executed in a cell when marked with "%%cython". Code analysis is available with "%%cython -a". Patch by Martín Gaitán. * Simple support for declaring Python object types in Python signature annotations. Currently requires setting the compiler directive ``annotation_typing=True``. * New directive ``use_switch`` (defaults to True) to optionally disable the optimization of chained if statement to C switch statements. * Defines dynamic_cast et al. in ``libcpp.cast`` and C++ heap data structure operations in ``libcpp.algorithm``. * Shipped header declarations in ``posix.*`` were extended to cover more of the POSIX API. Patches by Lars Buitinck and Mark Peek. * Optimizations * Simple calls to C implemented Python functions/methods are faster. This also speeds up many operations on builtins that Cython cannot otherwise optimise. * The "and"/"or" operators try to avoid unnecessary coercions of their arguments. They now evaluate the truth value of each argument independently and only coerce the final result of the whole expression to the target type (e.g. the type on the left side of an assignment). This also avoids reference counting overhead for Python values during evaluation and generally improves the code flow in the generated C code. * The Python expression "2 ** N" is optimised into bit shifting. See http://bugs.python.org/issue21420 * Cascaded assignments (a = b = ...) try to minimise the number of type coercions. * Calls to ``slice()`` are translated to a straight C-API call. * Bugs fixed * Crash when assigning memory views from ternary conditional expressions. * Nested C++ templates could lead to unseparated ">>" characters being generated into the C++ declarations, which older C++ compilers could not parse. * Sending SIGINT (Ctrl-C) during parallel cythonize() builds could hang the child processes. * No longer ignore local setup.cfg files for distutils in pyximport. Patch by Martin Teichmann. * Taking a ``char*`` from an indexed Python string generated unsafe reference counting code. * Set literals now create all of their items before trying to add them to the set, following the behaviour in CPython. This makes a difference in the rare case that the item creation has side effects and some items are not hashable (or if hashing them has side effects, too). * Cython no longer generates the cross product of C functions for code that uses memory views of fused types in function signatures (e.g. ``cdef func(floating[:] a, floating[:] b)``). This is considered the expected behaviour by most users and was previously inconsistent with other structured types like C arrays. Code that really wants all type combinations can create the same fused memoryview type under different names and use those in the signature to make it clear which types are independent. * Names that were unknown at compile time were looked up as builtins at runtime but not as global module names. Trying both lookups helps with globals() manipulation. * Fixed stl container conversion for typedef element types. * ``obj.pop(x)`` truncated large C integer values of x to ``Py_ssize_t``. * ``__init__.pyc`` is recognised as marking a package directory (in addition to .py, .pyx and .pxd). * Syntax highlighting in ``cython-mode.el`` for Emacs no longer incorrectly highlights keywords found as part of longer names. * Correctly handle ``from cython.submodule cimport name``. * Fix infinite recursion when using super with cpdef methods. * No-args ``dir()`` was not guaranteed to return a sorted list. * Other changes * The header line in the generated C files no longer contains the timestamp but only the Cython version that wrote it. This was changed to make builds more reproducible. * Removed support for CPython 2.4, 2.5 and 3.1. * The licensing implications on the generated code were clarified to avoid legal constraints for users. - Update to 0.20.2 (2014-06-16) * Features added * Some optimisations for set/frozenset instantiation. * Support for C++ unordered_set and unordered_map. * Bugs fixed * Access to attributes of optimised builtin methods (e.g. ``[].append.__name__``) could fail to compile. * Memory leak when extension subtypes add a memory view as attribute to those of the parent type without having Python object attributes or a user provided dealloc method. * Compiler crash on readonly properties in "binding" mode. * Auto-encoding with ``c_string_encoding=ascii`` failed in Py3.3. * Crash when subtyping freelist enabled Cython extension types with Python classes that use ``__slots__``. * Freelist usage is restricted to CPython to avoid problems with other Python implementations. * Memory leak in memory views when copying overlapping, contiguous slices. * Format checking when requesting non-contiguous buffers from ``cython.array`` objects was accidentally omitted in Py3. * C++ destructor calls in extension types could fail to compile in clang. * Buffer format validation failed for sequences of strings in structs. * Docstrings on extension type attributes in .pxd files were rejected. ------------------------------------------------------------------- Thu Jul 31 16:53:10 UTC 2014 - dimstar@opensuse.org - Rename rpmlintrc to %{name}-rpmlintrc. Follow the packaging guidelines. ------------------------------------------------------------------- Thu May 8 11:40:51 UTC 2014 - toddrme2178@gmail.com - Update to version 0.20.1 * List/Tuple literals multiplied by more than one factor were only multiplied by the last factor instead of all. * Lookups of special methods (specifically for context managers) could fail in Python <= 2.6/3.1. * Local variables were erroneously appended to the signature introspection of Cython implemented functions with keyword-only arguments under Python 3. * In-place assignments to variables with inferred Python builtin/extension types could fail with type errors if the result value type was incompatible with the type of the previous value. * The C code generation order of cdef classes, closures, helper code, etc. was not deterministic, thus leading to high code churn. * Type inference could fail to deduce C enum types. * Type inference could deduce unsafe or inefficient types from integer assignments within a mix of inferred Python variables and integer variables. ------------------------------------------------------------------- Tue Feb 4 08:50:21 UTC 2014 - speilicke@suse.com - Update to version 0.20: * Support for CPython 3.4. * Support for calling C++ template functions. * yield is supported in finally clauses. * The C code generated for finally blocks is duplicated for each exit case to allow for better optimisations by the C compiler. * Cython tries to undo the Python optimisationism of assigning a bound method to a local variable when it can generate better code for the direct call. * Constant Python float values are cached. * String equality comparisons can use faster type specific code in more cases than before. * String/Unicode formatting using the '%' operator uses a faster C-API call. * bytearray has become a known type and supports coercion from and to C strings. Indexing, slicing and decoding is optimised. Note that this may have an impact on existing code due to type inference. * Using cdef basestring stringvar and function arguments typed as basestring is now meaningful and allows assigning exactly str and unicode objects, but no subtypes of these types. * Support for the __debug__ builtin. * Assertions in Cython compiled modules are disabled if the running Python interpreter was started with the "-O" option. * Some types that Cython provides internally, such as functions and generators, are now shared across modules if more than one Cython implemented module is imported. * The type inference algorithm works more fine granular by taking the results of the control flow analysis into account. * A new script in bin/cythonize provides a command line frontend to the cythonize() compilation function (including distutils build). * The new extension type decorator @cython.no_gc_clear prevents objects from being cleared during cyclic garbage collection, thus making sure that object attributes are kept alive until deallocation. * During cyclic garbage collection, attributes of extension types that cannot create reference cycles due to their type (e.g. strings) are no longer considered for traversal or clearing. This can reduce the processing overhead when searching for or cleaning up reference cycles. * Package compilation (i.e. __init__.py files) now works, starting with Python 3.3. * The cython-mode.el script for Emacs was updated. Patch by Ivan Andrus. * An option common_utility_include_dir was added to cythonize() to save oft-used utility code once in a separate directory rather than as part of each generated file. * unraisable_tracebacks directive added to control printing of tracebacks of unraisable exceptions. ------------------------------------------------------------------- Tue Oct 22 14:18:37 UTC 2013 - toddrme2178@gmail.com - update to 0.19.2: * Some standard declarations were fixed or updated, including the previously incorrect declaration of ``PyBuffer_FillInfo()`` and some missing bits in ``libc.math``. * Heap allocated subtypes of ``type`` used the wrong base type struct at the C level. * Calling the unbound method dict.keys/value/items() in dict subtypes could call the bound object method instead of the unbound supertype method. * "yield" wasn't supported in "return" value expressions. * Using the "bint" type in memory views lead to unexpected results. It is now an error. * Assignments to global/closure variables could catch them in an illegal state while deallocating the old value. ------------------------------------------------------------------- Fri Oct 11 17:47:46 UTC 2013 - p.drouand@gmail.com - Implement update-alternatives ------------------------------------------------------------------- Wed Apr 3 06:50:48 UTC 2013 - arun@gmx.de - fixed python3 build by including 2to3 and python3 as dependencies ------------------------------------------------------------------- Wed Mar 27 12:17:42 UTC 2013 - speilicke@suse.com - Update to version 0.18: + Please see http://wiki.cython.org/ReleaseNotes-0.18 ------------------------------------------------------------------- Fri Nov 30 14:04:52 UTC 2012 - toddrme2178@gmail.com - Fix building on openSUSE 12.1 and 12.2 ------------------------------------------------------------------- Thu Nov 22 15:33:16 UTC 2012 - saschpe@suse.de - Update to version 0.17.2: + Please see http://wiki.cython.org/ReleaseNotes-0.18.2 - Drop excessive macro usage - No need for "-fno-strict-aliasing" anymore - One rpmlintrc is enough - Python3 binary suffix should be "-%{py3_ver}" ------------------------------------------------------------------- Thu Jun 14 12:24:59 UTC 2012 - toddrme2178@gmail.com - Fix building on openSUSE 11.4 ------------------------------------------------------------------- Fri May 25 07:47:16 UTC 2012 - toddrme2178@gmail.com - Fix .py/.pyc issues ------------------------------------------------------------------- Fri May 18 10:52:46 UTC 2012 - toddrme2178@gmail.com - Add python 3 package - Clean up spec file formatting - Remove setbadness from rplintrc files
