------------------------------------------------------------------- Tue Apr 2 09:50:48 UTC 2024 - Dirk Müller <dmueller@suse.com> - update to 3.0.10: * Cython generated incorrect self-casts when directly calling final methods of subtypes. * Internal C names generated from C function signatures could become too long for MSVC. * The noexcept warnings could be misleading in some cases. * The @cython.ufunc implementation could generate incomplete C code. * The libcpp.complex declarations could result in incorrect C++ code. Patch by Raffi Enficiaud. * Several tests were adapted to work with both NumPy 1.x and 2.0. Patch by Matti Picus. * C compiler warnings when the freelist implementation is disabled (e.g. on PyPy) were fixed. It can now be disabled explicitly with the C macro guard CYTHON_USE_FREELISTS=0. * Some C macro guards for feature flags were missing from the NOGIL Python configuration. * Some recently added builtins were unconditionally looked up at module import time (if used by user code) that weren't available on all Python versions and could thus fail the import. * A performance hint regarding exported pxd declarations was improved. ------------------------------------------------------------------- Mon Mar 18 10:56:20 UTC 2024 - Dirk Müller <dmueller@suse.com> - update to 3.0.9: * Assigning const values to non-const variables now issues a warning. * Using noexcept on a function returning Python objects now issues a warning. * Some C-API usage was updated for the upcoming CPython 3.13. Patches by Victor Stinner et al. * The deprecated Py_UNICODE type is no longer used, unless required by user code. * std::string.replace() declarations were added to libcpp.string. Patch by Kieran Geary. * Cython generates incorrect (but harmless) self-casts when directly calling final methods of subtypes. Lacking a better solution, the errors that recent gcc versions produce have been silenced for the time being. Original patch by Michał Górny. * Unused variable warnings about clineno were fixed when C lines in tracebacks are disabled. * Subclass deallocation of extern classes could crash if the base class uses GC. Original patch by Jason Fried. * Type checks for Python memoryview could use an invalid C function. Patch by Xenia Lu. * Calling final fused functions could generate invalid C code. * Declaring extern enums multiple times could generate invalid C code. * pyximport used relative paths incorrectly. Patch by Stefano Rivera. * Running Cython with globbing characters ([]*?) in the module search path could fail. * Literal strings that include braces could change the C code indentation. * The "enum class not importable" warning is now only issued once per enum type. ------------------------------------------------------------------- Sun Jan 14 15:30:24 UTC 2024 - Dirk Müller <dmueller@suse.com> - update to 3.0.8: * Using const together with defined fused types could fail to compile. (Github issue :issue:`5230`) * A "use after free" bug was fixed in parallel sections. (Github issue :issue:`5922`) * Several types were not available as cython.* types in pure Python code. * The generated code is now correct C89 again, removing some C++ style // comments and C99-style declaration-after-code code ordering. This is still relevant for some ols C compilers, specifically ones that match old Python 2.7 installations. ------------------------------------------------------------------- Tue Jan 2 22:01:07 UTC 2024 - Dirk Müller <dmueller@suse.com> - require setuptools ------------------------------------------------------------------- Thu Dec 21 16:15:20 UTC 2023 - Dirk Müller <dmueller@suse.com> - update to 3.0.7: * In the iterator of generator expressions, ``await`` and ``yield`` were not correctly analysed. * ``cpdef`` enums with the same name cimported from different modules could lead to invalid C code. * Some declarations in ``cpython.unicode`` were fixed and extended. * Compiling fused types used in pxd files could crash Cython in Python 3.11+. * Source files with non-ASCII file names could crash Cython. * Includes all bug-fixes and features from the 0.29 maintenance branch ------------------------------------------------------------------- Mon Nov 27 08:49:57 UTC 2023 - Dirk Müller <dmueller@suse.com> - update to 3.0.6: * Features added * Fused def function dispatch is a bit faster. * Declarations for the ``wchar`` PyUnicode API were added. * The Python "nogil" fork is now also detected with the new ``Py_GIL_DISABLED`` macro. * Patch by Hugo van Kemenade (Github issue :issue:`583652`) * Bugs fixed * Comparing dataclasses could give different results than Python. * ``float(std::string)`` generated invalid C code. * Using ``cpdef`` functions with ``cimport_from_pyx`` failed. * A crash was fixed when string-formatting a Python value fails. * On item access, Cython could try the sequence protocol before the mapping protocol * in some cases if an object supports both. * A C compiler warning was resolved. * Complex numbers failed to compile in MSVC with C11. * Patch by Lysandros Nikolaou. (Github issue :issue:`5809`) * Some issues with the Limited API and with PyPy were resolved. * A C++ issue in Python 3.13 was resolved. * Several directives are now also available (as no-ops) in Python code. * An error message was corrected. ------------------------------------------------------------------- Mon Nov 20 12:09:27 UTC 2023 - Dirk Müller <dmueller@suse.com> - avoid obsoletes on provides as we now had a version update ------------------------------------------------------------------- Fri Nov 10 13:13:54 UTC 2023 - Dirk Müller <dmueller@suse.com> - update to 3.0.5: * Preliminary support for CPython 3.13a1 was added to allow early testing. * Bugs fixed * A compiler crash was fixed. * A typo in the ``always_allow_keywords`` directive for Python code was fixed. * Some C compiler warnings were resolved. ------------------------------------------------------------------- Wed Oct 18 06:15:17 UTC 2023 - Daniel Garcia Moreno <daniel.garcia@suse.com> - update to version 3.0.4: * Features added - A new compiler directive show_performance_hints was added to disable the newly added performance hint output. (Github issue :issue:`5748`) * Bugs fixed - `cythonize` required ``distutils even for operations that did not build binaries. (Github issue :issue:`5751`) - A regression in 3.0.3 was fixed that prevented calling inline functions from another inline function in .pxd files. (Github issue :issue:`5748`) - Some C compiler warnings were resolved. Patch by Pierre Jolivet. (Github issue :issue:`5756`) ------------------------------------------------------------------- Tue Oct 17 08:57:05 UTC 2023 - Daniel Garcia Moreno <daniel.garcia@suse.com> - update to version 3.0.3: * Features added - More warnings were added to help users migrate and avoid bugs. (Github issue #5650) - A warning-like category for performance hints was added that bypasses -Werror. (Github issue #5673) - FastGIL now uses standard thread_local in C++. (Github issue #5640) - reference_wrapper was added to libcpp.functional. Patch by Vyas Ramasubramani. (Github issue #5671) - The cythonize command now supports the --cplus option known from the cython command. (Github issue #5736) * Bug fixed - Performance regressions where the GIL was needlessly acquired were fixed. (Github issues #5670, #5700) - A reference leak for exceptions in Python 3.12 was resolved. Patch by Eric Johnson. (Github issue #5724) - fastcall calls with keyword arguments generated incorrect C code. (Github issue #5665) - Assigning the type converted result of a conditional (if-else) expression to int or bool variables could lead to incorrect C code. (Github issue #5731) - Early (unlikely) failures in Python function wrappers no longer set a traceback in order to simplify the C code flow. Being mostly memory allocation errors, they probably would never have created a traceback anyway. (Github issue #5681) - Relative cimports from packages with __init__.py files could fail. (Github issue #5715) - Several issues with the Limited API support were resolved. (Github issues #5641, #5648, #5689) - The code generated for special-casing both Cython functions and PyCFunctions was cleaned up to avoid calling C-API functions that were not meant for the other type respectively. This could previously trigger assertions in CPython debug builds and now also plays better with the Limited API. (Github issues #4804, #5739) - Fix some C compiler warnings. Patches by Ralf Gommers, Oleksandr Pavlyk, Sebastian Koslowski et al. (Github issues #5651, #5663, #5668, #5717, #5726, #5734) - Generating gdb debugging information failed when using generator expressions. Patch by Oleksandr Pavlyk. (Github issue #5552) - Passing a setuptools.Extension into cythonize() instead of a distutils.Extension could make it miss the matching extensions. - cython -M needlessly required distutils, which made it fail in Python 3.12. (Github issue #5681) * Other changes - The visible deprecation warning for DEF was removed again since it proved difficult for some users to migrate away from it. The statement is still meant to be removed at some point (and thus, like IF, should not be used in new code), but the time for sunset is probably not around the corner. (Github issue #4310) - The np_pythran option raise a DeprecationWarning if it receives other values than True and False. This will eventually be disallowed (in line with all other boolean options). ------------------------------------------------------------------- Sun Aug 27 21:37:49 UTC 2023 - Arun Persaud <arun@gmx.de> - update to version 3.0.2: * Bugs fixed + Using None as default value for arguments annotated as int could crash Cython. (Github issue :issue:`5643`) + Default values of fused types that include complex could generate invalid C code with -DCYTHON_CCOMPLEX=0. (Github issue :issue:`5644`) + Using C++ enum class types in extension type method signatures could generate invalid C code. (Github issue :issue:`5637`) - changes from version 3.0.1: * Features added + The error messages regarding exception declarations were improved in order to give better help about possible reasons and fixes. (Github issue :issue:`5547`) * Bugs fixed + Memory view types in Python argument annotations no longer accept None. They now require an explicit Optional[] or a None default value in order to allow None to be passed. This was an oversight in the 3.0.0 release and is a BACKWARDS INCOMPATIBLE change. However, since it only applies to code using Python syntax, it probably only applies to newly written code that was written for Cython 3.0 and can easily be adapted. In most cases, we expect that this change will avoid bugs in user code rather than produce problems. (Github issue :issue:`5612`) + nogil functions using parallel code could freeze when called with the GIL held. (Github issues :issue:`5564`, :issue:`5573`) + Relative cimports could end up searching globally and find the same package installed elsewhere, potentially in another version. (Github issue :issue:`5511`) + Attribute lookups on known standard library modules could accidentally search in the module namespace instead. (Github issue :issue:`5536`) + Using constructed C++ default arguments could generate invalid C++ code. (Github issue :issue:`5553`) + libcpp.memory.make_unique() was lacking C++ exception handling. (Github issue :issue:`5560`) + Some non-public and deprecated CAPI usages were replaced by public (and thus more future proof) API code. + Many issues with the Limited API support were resolved. Patches by Lisandro Dalcin et al. (Github issues :issue:`5549`, :issue:`5550`, :issue:`5556`, :issue:`5605`, :issue:`5617`) + Some C compiler warnings were resolved. Patches by Matti Picus et al. (Github issues :issue:`5557`, :issue:`5555`) + Large Python integers are now stored in hex instead of decimal strings to work around security limits in Python and generally speed up their Python object creation. + NULL could not be used as default for fused type pointer arguments. (Github issue :issue:`5554`) + C functions that return pointer types now return NULL as default exception value. Previously, calling code wasn't aware of this and always tested for raised exceptions. (Github issue :issue:`5554`) + Untyped literal default arguments in fused functions could generate invalid C code. (Github issue :issue:`5614`) + C variables declared as const could generate invalid C code when used in closures, generator expressions, ctuples, etc. (Github issues :issue:`5558`, :issue:`5333`) + Enums could not refer to previously defined enums in their definition. (Github issue :issue:`5602`) + The Python conversion code for anonymous C enums conflicted with regular int conversion. (Github issue :issue:`5623`) + Using memory views for property methods (and other special methods) could lead to refcounting problems. (Github issue :issue:`5571`) + Star-imports could generate code that tried to assign to constant C macros like PY_SSIZE_T_MAX and PY_SSIZE_T_MIN. Patch by Philipp Wagner. (Github issue :issue:`5562`) + CYTHON_USE_TYPE_SPECS can now be (explicitly) enabled in PyPy. + The template parameter "delimeters" in the Tempita Template class was corrected to "delimiters". The old spelling is still available in the main template API but now issues a DeprecationWarning. (Github issue :issue:`5608`) + The cython --version output is now less likely to reach both stdout and stderr. Patch by Eli Schwartz. (Github issue :issue:`5504`) + The sdist was missing the Shadow.pyi stub file. ------------------------------------------------------------------- Wed Jul 19 12:23:38 UTC 2023 - Matej Cepl <mcepl@suse.com> - Update to the official release of 3.0.0: - The complete list is seriously long, so I would relegate you to https://github.com/cython/cython/blob/master/CHANGES.rst - The implemented PEPs are: - PEP-3131: Supporting Non-ASCII Identifiers - PEP-479: generator_stop (enabled by default for language_level=3) - PEP-487: Simpler customisation of class creation - PEP-563: Postponed Evaluation of Annotations - PEP-570: Positional-Only Parameters - PEP-572: Assignment Expressions (a.k.a. the walrus operator :=) - PEP-590: Vectorcall protocol - PEP-614: Relaxing Grammar Restrictions On Decorators - Cython supports all released versions of Python from 2.7 to 3.11 (and some experimental parts of 3.12) inclusive. ------------------------------------------------------------------- Mon Jul 10 19:03:16 UTC 2023 - Matej Cepl <mcepl@suse.com> - Clean up SPEC file. ------------------------------------------------------------------- Sat Jul 8 20:26:51 UTC 2023 - Arun Persaud <arun@gmx.de> - update to version 0.29.36: * Async generators lost their return value in PyPy. (Github issue :issue:`5465`) * The outdated C macro _PyGC_FINALIZED() is no longer used in Py3.9+. * The deprecated Py_OptimizeFlag is no longer used in Python 3.9+. (Github issue :issue:`5343`) * Using the global __debug__ variable but not assertions could lead to compile errors. * The broken HTML template support was removed from Tempita. (Github issue :issue:`3309`) ------------------------------------------------------------------- Sat May 27 21:05:03 UTC 2023 - Dirk Müller <dmueller@suse.com> - update to 0.29.35: * A garbage collection enabled subtype of a non-GC extension type could call into the deallocation function of the super type with GC tracking enabled. This could lead to crashes during deallocation if GC was triggered on the type at the same time. * Some C compile failures and crashes in CPython 3.12 were resolved. * ``except + nogil`` was syntactically not allowed. * ``except +nogil`` (i.e. defining a C++ exception handling function called ``nogil``) is now disallowed to prevent typos. * A C compile failure in PyPy 3.10 was resolved. * Cython modules now use PEP-489 multi-phase init by default in PyPy 3.9 and later. * API header files generated by different Cython versions can now be included in the same C file. * Function signatures containing a type like `tuple[()]` could not be printed. ------------------------------------------------------------------- Fri Apr 21 12:20:26 UTC 2023 - Dirk Müller <dmueller@suse.com> - add sle15_python_module_pythons (jsc#PED-68) ------------------------------------------------------------------- Thu Apr 13 22:40:49 UTC 2023 - Matej Cepl <mcepl@suse.com> - Make calling of %{sle15modernpython} optional. ------------------------------------------------------------------- Mon Apr 3 19:58:40 UTC 2023 - Dirk Müller <dmueller@suse.com> - update to 0.29.34: * A refence leak of the for-loop list/tuple iterable was resolved if the for-loop's ``else:`` branch executes a ``break`` for an outer loop. * Some C compile failures in CPython 3.12 were resolved. * Some old usages of the deprecated Python ``imp`` module were replaced with ``importlib``. * Patch by Matúš Valo. (Github issue :issue:`5300`) * Some issues with ``depfile`` generation were resolved. * Patches by Eli Schwartz. (Github issues :issue:`5279`, :issue:`5291`) ------------------------------------------------------------------- Sat Jan 7 12:27:04 UTC 2023 - Dirk Müller <dmueller@suse.com> - update to 0.29.33: * The ``cythonize`` and ``cython`` commands have a new option ``-M`` / ``--depfile`` to generate ``.dep`` dependency files for the compilation unit. This can be used by external build tools to track these dependencies. * ``const`` fused types could not be used with memory views. * ``wstr`` usage was removed in Python 3.12 and later (PEP-623). * A type check assertion for Cython functions failed in debug Python builds. * Fixed various compiler warnings. * Fixed error when calculating complex powers of negative numbers. * Corrected a small mis-formatting of exception messages on Python 2. * The ``PyUnicode_AsUTF8AndSize()`` C-API function was missing from the CPython declarations. * A performance problem in the compiler was resolved when nesting conditional expressions. * Test suite problems with recent NumPy and CPython versions were resolved. * Other changes * The undocumented, untested and apparently useless syntax ``from somemodule cimport class/struct/union somename`` was deprecated in anticipation of its removal in Cython 3. The type modifier is not needed here and a plain ``cimport`` of the name will do. * Properly disable generation of descriptor docstrings on PyPy since they cause crashes. It was previously disabled, but only accidentally via a typo. * The ``cpow`` directive of Cython 3.0 is available as a no-op. ------------------------------------------------------------------- Wed Oct 26 01:33:21 UTC 2022 - Steve Kowalik <steven.kowalik@suse.com> - Remove leftover Python 2 gubbins. - Stop using handrolled macros for install and update-alternatives, switch to the provided ones. - Update package names in rpmlintrc. ------------------------------------------------------------------- Tue Aug 2 11:51:50 UTC 2022 - Otto Hollmann <otto.hollmann@suse.com> - Update to 0.29.32: - Bugs fixed: * Revert "Using memoryview typed arguments in inner functions is now rejected as unsupported." * from module import * failed in 0.29.31 when using memoryviews - Changes from 0.29.31: - Features added: * A new argument --module-name was added to the cython command to provide the (one) exact target module name from the command line. - Bugs fixed: * Use importlib.util.find_spec() instead of the deprecated importlib.find_loader() function when setting up the package path at import-time. * Require the C compiler to support the two-arg form of va_start on Python 3.10 and higher. * Make fused_type subscriptable in Shadow.py. * Fix the incorrect code generation of the target type in bytearray loops. * Atomic refcounts for memoryviews were not used on some GCC versions by accident. * Silence some GCC -Wconversion warnings in C utility code. * Tuple multiplication was ignored in expressions such as [*(1,) * 2]. * Calling append methods on extension types could fail to find the method in some cases. * Ensure that object buffers (e.g. ndarray[object, ndim=1]) containing NULL pointers are safe to use, returning None instead of the NULL pointer. * Using memoryview typed arguments in inner functions is now rejected as unsupported. * Compilation could fail on systems (e.g. FIPS) that block MD5 checksums at runtime. * Experimental adaptations for the CPython "nogil" fork was added. Note that there is no official support for this in Cython 0.x. ------------------------------------------------------------------- Wed May 18 08:35:39 UTC 2022 - Paolo Stivanin <info@paolostivanin.com> - update to 0.29.30: * Avoid acquiring the GIL at the end of nogil functions. This change was backported in order to avoid generating wrong C code that would trigger C compiler warnings with tracing support enabled. * Function definitions in finally: clauses were not correctly generated. * A case where C-API functions could be called with a live exception set was fixed. * Cython now correctly generates Python methods for both the provided regular and reversed special numeric methods of extension types. * The C union type in pure Python mode mishandled some field names. ------------------------------------------------------------------- Sun Mar 20 20:33:02 UTC 2022 - Dirk Müller <dmueller@suse.com> - update to 0.29.28: * Due to backwards incompatible changes in CPython 3.11a4, the feature flags ``CYTHON_FAST_THREAD_STATE`` and ``CYTHON_USE_EXC_INFO_STACK`` are now disabled in Python 3.11 and later. They are enabled again in Cython 3.0. Patch by David Woods. (Github issue #4610) * A C compiler warning in older PyPy versions was resolved. Patch by Matti Picus. (Github issue #4236) ------------------------------------------------------------------- Wed Feb 2 17:54:50 UTC 2022 - Matej Cepl <mcepl@suse.com> - Make the running the test suite conditional (default off). Seven hours of running it is just too much. ------------------------------------------------------------------- Mon Jan 31 20:31:01 UTC 2022 - Matej Cepl <mcepl@suse.com> - Enable running of the test suite. ------------------------------------------------------------------- Mon Jan 31 13:46:21 UTC 2022 - Paolo Stivanin <info@paolostivanin.com> - update to 0.29.27: * The ``cythonize`` command has a new option ``-M`` to generate ``.dep`` dependency files for the compilation unit. This can be used by external build tools to track these dependencies. * Calls to ``range()`` with more than three arguments did not fail. * Some C compiler warnings about missing type struct initialisers in Py3.10 were resolved. * Cython no longer warns about using OpenMP 3.0 features since they are now considered generally available. ------------------------------------------------------------------- Tue Jan 4 15:59:48 UTC 2022 - Dirk Müller <dmueller@suse.com> - update to 0.29.26: * An incompatibility with CPython 3.11.0a3 was resolved. * The ``in`` operator failed on literal lists with starred expressions. * A C compiler warning in PyPy about a missing struct field initialisation was resolved. ------------------------------------------------------------------- Mon Dec 6 20:16:04 UTC 2021 - Dirk Müller <dmueller@suse.com> - update to 0.29.25: * Several incompatibilities with CPython 3.11 were resolved. * Some C compiler warnings were resolved. * C++ ``std::move()`` should only be used automatically in MSVC versions that support it. * The ``Py_hash_t`` type failed to accept arbitrary "index" values. * Avoid copying unaligned 16-bit values since some platforms require them to be aligned. Use memcpy() instead to let the C compiler decide how to do it. * Cython crashed on invalid truthiness tests on C++ types without ``operator bool``. * The declaration of ``PyUnicode_CompareWithASCIIString()`` in ``cpython.unicode`` was incorrect. ------------------------------------------------------------------- Wed Jul 14 08:28:08 UTC 2021 - Paolo Stivanin <info@paolostivanin.com> - Update to 0.29.24: * Inline functions in pxd files that used memory views could lead to invalid C code if the module that imported from them does not use memory views. * Several declarations in ``libcpp.string`` were added and corrected. * Pickling unbound Cython compiled methods failed. * The tracing code was adapted to work with CPython 3.10. * The optimised ``in`` operator failed on unicode strings in Py3.9 and later that were constructed from an external ``wchar_t`` source. Also, related C compiler warnings about deprecated C-API usage were resolved. * Some compiler crashes were resolved. * An incorrect warning about 'unused' generator expressions was removed. * The attributes ``gen.gi_frame`` and ``coro.cr_frame`` of Cython compiled generators and coroutines now return an actual frame object for introspection, instead of ``None``. - Drop cython_use_imgmath.patch ------------------------------------------------------------------- Wed Apr 21 21:19:17 UTC 2021 - Dirk Müller <dmueller@suse.com> - update to 0.29.23: * Some problems with Python 3.10 were resolved. Patches by Victor Stinner and David Woods. (Github issues #4046, #4100) * An incorrect "optimisation" was removed that allowed changes to a keyword dict to leak into keyword arguments passed into a function. Patch by Peng Weikang. (Github issue #3227) * Multiplied str constants could end up as bytes constants with language_level=2. Patch by Alphadelta14 and David Woods. (Github issue #3951) * ``PY_SSIZE_T_CLEAN`` does not get defined any more if it is already defined. Patch by Andrew Jones. (Github issue #4104) ------------------------------------------------------------------- Tue Feb 23 07:22:13 UTC 2021 - Paolo Stivanin <info@paolostivanin.com> - Update to 0.29.22 * Some declarations were added to the provided pxd includes. Patches by Zackery Spytz and John Kirkham. (Github issues #3811, #3882, #3899, #3901) * A crash when calling certain functions in Py3.9 and later was resolved. (Github issue #3917) * ``const`` memory views of structs failed to compile. (Github issue #2251) * ``const`` template declarations could not be nested. Patch by Ashwin Srinath. (Github issue #1355) * The declarations in the ``cpython.pycapsule`` module were missing their ``const`` modifiers and generated incorrect C code. Patch by Warren Weckesser. (Github issue #3964) * Casts to memory views failed for fused dtypes. Patch by David Woods. (Github issue #3881) * ``repr()`` was assumed to return ``str`` instead of ``unicode`` with ``language_level=3`` * Calling ``cpdef`` functions from cimported modules crashed the compiler. Patch by David Woods. (Github issue #4000) * Cython no longer validates the ABI size of the NumPy classes it compiled against. * A C compiler warning about enum value casting was resolved in GCC. (Github issue #2749) * Coverage reporting in the annotated HTML file failed in Py3.9. Patch by Nick Pope. (Github issue #3865) * The embedding code now reports Python errors as exit status. * Long type declarations could lead to (harmless) random changes in the C file when used in auto-generated Python wrappers or pickled classes. ------------------------------------------------------------------- Wed Jul 8 22:36:13 UTC 2020 - Ondřej Súkup <mimi.vx@gmail.com> - Update TO 0.29.21 * Fix a regression in 0.29.20 where __div__ failed to be found in extension types * Fix a regression in 0.29.20 where a call inside of a finally clause could fail to compile * Zero-sized buffers could fail to validate as C/Fortran-contiguous. * exec() did not allow recent Python syntax features in Py3.8+ due to https://bugs.python.org/issue35975 * Binding staticmethods of Cython functions were not behaving like Python methods in Py3 * Pythran calls to NumPy methods no longer generate useless method lookup code. * The PyUnicode_GET_LENGTH() macro was missing from the cpython.* declarations * The deprecated PyUnicode_*() C-API functions are no longer used, except for Unicode strings that contain lone surrogates. Unicode strings that contain non-BMP characters or surrogate pairs now generate different C code on 16-bit Python 2.x Unicode deployments (such as MS-Windows). Generating the C code on Python 3.x is recommended in this case * Some template parameters were missing from the C++ std::unordered_map declaration * Several internal code generation issues regarding temporary variables were resolved ------------------------------------------------------------------- Thu Jun 11 06:30:55 UTC 2020 - Paolo Stivanin <info@paolostivanin.com> - Update to 0.29.20 * Nested try-except statements with multiple return statements could crash due to incorrect deletion of the except as target variable. * The @classmethod decorator no longer rejects unknown input from other decorators. * Fused types could leak into unrelated usages. Patch by David Woods. * Now uses Py_SET_SIZE() and Py_SET_REFCNT() in Py3.9+ to avoid low-level write access to these object field * The built-in abs() function could lead to undefined behaviour when used on the negative-most value of a signed C integer type * Usages of sizeof() and typeid() on uninitialised variables no longer produce a warning * The C++ typeid() function was allowed in C mode * The error position reported for errors found in f-strings was misleading * The new c_api_binop_methods directive was added for forward compatibility, but can only be set to True (the current default value). It can be disabled in Cython 3.0 ------------------------------------------------------------------- Thu May 21 15:16:20 UTC 2020 - Paolo Stivanin <info@paolostivanin.com> - Update to 0.29.19 * Exception position reporting could run into race conditions on threaded code. It now uses function-local variables again. * Error handling early in the module init code could lead to a crash. * Error handling in cython.array creation was improved to avoid calling C-API functions with an error held. * A memory corruption was fixed when garbage collection was triggered during calls to PyType_Ready() of extension type subclasses. (Github issue #3603) * Memory view slicing generated unused error handling code which could negatively impact the C compiler optimisations for parallel OpenMP code etc. Also, it is now helped by static branch hints.

Patch by Kryštof Pilnáček. (Github issue #2638) + A struct field type in the cpython.array declarations was corrected. Patch by John Kirkham. (Github issue #2712) ------------------------------------------------------------------- Wed Oct 17 15:29:49 UTC 2018 - Arun Persaud <arun@gmx.de> - update to version 0.29: * Features added + PEP-489 multi-phase module initialisation has been enabled again. Module reloads in other subinterpreters raise an exception to prevent corruption of the static module state. + A set of mypy compatible PEP-484 declarations were added for Cython's C data types to integrate with static analysers in typed Python code. They are available in the Cython/Shadow.pyi module and describe the types in the special cython module that can be used for typing in Python code. Original patch by Julian Gethmann. (Github issue #1965) + Memoryviews are supported in PEP-484/526 style type declarations. (Github issue #2529) + @cython.nogil is supported as a C-function decorator in Python code. (Github issue #2557) + Raising exceptions from nogil code will automatically acquire the GIL, instead of requiring an explicit with gil block. + C++ functions can now be declared as potentially raising both C++ and Python exceptions, so that Cython can handle both correctly. (Github issue #2615) + cython.inline() supports a direct language_level keyword argument that was previously only available via a directive. + A new language level name 3str was added that mostly corresponds to language level 3, but keeps unprefixed string literals as type 'str' in both Py2 and Py3, and the builtin 'str' type unchanged. This will become the default in the next Cython release and is meant to help user code a) transition more easily to this new default and b) migrate to Python 3 source code semantics without making support for Python 2.x difficult. + In CPython 3.6 and later, looking up globals in the module dict is almost as fast as looking up C globals. (Github issue #2313) + For a Python subclass of an extension type, repeated method calls to non-overridden cpdef methods can avoid the attribute lookup in Py3.6+, which makes them 4x faster. (Github issue #2313) + (In-)equality comparisons of objects to integer literals are faster. (Github issue #2188) + Some internal and 1-argument method calls are faster. + Modules that cimport many external extension types from other Cython modules execute less import requests during module initialisation. + Constant tuples and slices are deduplicated and only created once per module. (Github issue #2292) + The coverage plugin considers more C file extensions such as .cc and .cxx. (Github issue #2266) + The cythonize command accepts compile time variable values (as set by DEF) through the new -E option. Patch by Jerome Kieffer. (Github issue #2315) + pyximport can import from namespace packages. Patch by Prakhar Goel. (Github issue #2294) + Some missing numpy and CPython C-API declarations were added. Patch by John Kirkham. (Github issues #2523, #2520, #2537) + Declarations for the pylifecycle C-API functions were added in a new .pxd file cpython.pylifecycle. + The Pythran support was updated to work with the latest Pythran 0.8.7. Original patch by Adrien Guinet. (Github issue #2600) + %a is included in the string formatting types that are optimised into f-strings. In this case, it is also automatically mapped to %r in Python 2.x. + New C macro CYTHON_HEX_VERSION to access Cython's version in the same style as PY_HEX_VERSION. + Constants in libc.math are now declared as const to simplify their handling. + An additional check_size clause was added to the ctypedef class name specification to allow suppressing warnings when importing modules with backwards-compatible PyTypeObject size changes. Patch by Matti Picus. (Github issue #2627) * Bugs fixed + The exception handling in generators and coroutines under CPython 3.7 was adapted to the newly introduced exception stack. Users of Cython 0.28 who want to support Python 3.7 are encouraged to upgrade to 0.29 to avoid potentially incorrect error reporting and tracebacks. (Github issue #1958) + Crash when importing a module under Stackless Python that was built for CPython. Patch by Anselm Kruis. (Github issue #2534) + 2-value slicing of typed sequences failed if the start or stop index was None. Patch by Christian Gibson. (Github issue #2508) + Multiplied string literals lost their factor when they are part of another constant expression (e.g. 'x' * 10 + 'y' => 'xy'). + String formatting with the '%' operator didn't call the special __rmod__() method if the right side is a string subclass that implements it. (Python issue 28598) + The directive language_level=3 did not apply to the first token in the source file. (Github issue #2230) + Overriding cpdef methods did not work in Python subclasses with slots. Note that this can have a performance impact on calls from Cython code. (Github issue #1771) + Fix declarations of builtin or C types using strings in pure python mode. (Github issue #2046) + Generator expressions and lambdas failed to compile in @cfunc functions. (Github issue #459) + Global names with const types were not excluded from star-import assignments which could lead to invalid C code. (Github issue #2621) + Several internal function signatures were fixed that lead to warnings in gcc-8. (Github issue #2363) + The numpy helper functions set_array_base() and get_array_base() were adapted to the current numpy C-API recommendations. Patch by Matti Picus. (Github issue #2528) + Some NumPy related code was updated to avoid deprecated API usage. Original patch by jbrockmendel. (Github issue #2559) + Several C++ STL declarations were extended and corrected. Patch by Valentin Valls. (Github issue #2207) + C lines of the module init function were unconditionally not reported in exception stack traces. Patch by Jeroen Demeyer. (Github issue #2492) + When PEP-489 support is enabled, reloading the module overwrote any static module state. It now raises an exception instead, given that reloading is not actually supported. + Object-returning, C++ exception throwing functions were not checking that the return value was non-null. Original patch by Matt Wozniski (Github Issue #2603) + The source file encoding detection could get confused if the c_string_encoding directive appeared within the first two lines. (Github issue #2632) + Cython generated modules no longer emit a warning during import when the size of the NumPy array type is larger than what was found at compile time. Instead, this is assumed to be a backwards compatible change on NumPy side. * Other changes + Cython now emits a warning when no language_level (2, 3 or '3str') is set explicitly, neither as a cythonize() option nor as a compiler directive. This is meant to prepare the transition of the default language level from currently Py2 to Py3, since that is what most new users will expect these days. The future default will, however, not enforce unicode literals, because this has proven a major obstacle in the support for both Python 2.x and 3.x. The next major release is intended to make this change, so that it will parse all code that does not request a specific language level as Python 3 code, but with str literals. The language level 2 will continue to be supported for an indefinite time. + The documentation was restructured, cleaned up and examples are now tested. The NumPy tutorial was also rewritten to simplify the running example. Contributed by Gabriel de Marmiesse. (Github issue #2245) + Cython compiles less of its own modules at build time to reduce the installed package size to about half of its previous size. This makes the compiler slightly slower, by about 5-7%. ------------------------------------------------------------------- Sat Aug 11 16:12:10 UTC 2018 - arun@gmx.de - update to version 0.28.5: * The discouraged usage of GCC's attribute optimize("Os") was replaced by the similar attribute cold to reduce the code impact of the module init functions. (Github issue #2494) * A reference leak in Py2.x was fixed when comparing str to unicode for equality. ------------------------------------------------------------------- Thu Jul 12 03:33:30 UTC 2018 - arun@gmx.de - update to version 0.28.4: * Bugs fixed + Reallowing tp_clear() in a subtype of an @no_gc_clear extension type generated an invalid C function call to the (non-existent) base type implementation. (Github issue #2309) + Exception catching based on a non-literal (runtime) tuple could fail to match the exception. (Github issue #2425) + Compile fix for CPython 3.7.0a2. (Github issue #2477) ------------------------------------------------------------------- Sun May 27 16:30:35 UTC 2018 - arun@gmx.de - update to version 0.28.3: * Set iteration was broken in non-CPython since 0.28. * UnicodeEncodeError in Py2 when %s formatting is optimised for unicode strings. (Github issue #2276) * Work around a crash bug in g++ 4.4.x by disabling the size reduction setting of the module init function in this version. (Github issue #2235) ------------------------------------------------------------------- Wed Apr 18 02:15:50 UTC 2018 - toddrme2178@gmail.com - Version update to 0.28.2 + Features added * ``abs()`` is faster for Python long objects. * The C++11 methods ``front()`` and ``end()`` were added to the declaration of ``libcpp.string``. Patch by Alex Huszagh. (Github issue #2123) * The C++11 methods ``reserve()`` and ``bucket_count()`` are declared for ``std::unordered_map``. Patch by Valentin Valls. (Github issue #2168) + Bugs fixed * The copy of a read-only memoryview was considered read-only as well, whereas a common reason to copy a read-only view is to make it writable. The result of the copying is now a writable buffer by default. (Github issue #2134) * The ``switch`` statement generation failed to apply recursively to the body of converted if-statements. * ``NULL`` was sometimes rejected as exception return value when the returned type is a fused pointer type. Patch by Callie LeFave. (Github issue #2177) * Fixed compatibility with PyPy 5.11. Patch by Matti Picus. (Github issue #2165) + Other changes * The NumPy tutorial was rewritten to use memoryviews instead of the older buffer declaration syntax. Contributed by Gabriel de Marmiesse. (Github issue #2162) ------------------------------------------------------------------- Mon Mar 19 13:23:58 UTC 2018 - tchvatal@suse.com - Version update to 0.28.1: * PyFrozenSet_New() was accidentally used in PyPy where it is lacking from the C-API. * Assignment between some C++ templated types were incorrectly rejected when the templates mix const with ctypedef. (Github issue #2148) * Undeclared C++ no-args constructors in subclasses could make the compilation fail if the base class constructor was declared without nogil. (Github issue #2157) * Bytes %-formatting inferred basestring (bytes or unicode) as result type in some cases where bytes would have been safe to infer. (Github issue #2153) * None was accidentally disallowed as typed return value of dict.pop(). ------------------------------------------------------------------- Sat Mar 17 00:30:56 UTC 2018 - arun@gmx.de - update to version 0.28: * Features added + Cdef classes can now multiply inherit from ordinary Python classes. (The primary base must still be a c class, possibly object, and the other bases must not be cdef classes.) + Type inference is now supported for Pythran compiled NumPy expressions. Patch by Nils Braun. (Github issue #1954) + The const modifier can be applied to memoryview declarations to allow read-only buffers as input. (Github issues #1605, #1869) + C code in the docstring of a cdef extern block is copied verbatimly into the generated file. Patch by Jeroen Demeyer. (Github issue #1915) + When compiling with gcc, the module init function is now tuned for small code size instead of whatever compile flags were provided externally. Cython now also disables some code intensive optimisations in that function to further reduce the code size. (Github issue #2102) + Decorating an async coroutine with @cython.iterable_coroutine changes its type at compile time to make it iterable. While this is not strictly in line with PEP-492, it improves the interoperability with old-style coroutines that use yield from instead of await. + The IPython magic has preliminary support for JupyterLab. (Github issue #1775) + The new TSS C-API in CPython 3.7 is supported and has been backported. Patch by Naotoshi Seo. (Github issue #1932) + Cython knows the new Py_tss_t type defined in PEP-539 and automatically initialises variables declared with that type to Py_tss_NEEDS_INIT, a value which cannot be used outside of static assignments. + The set methods .remove() and .discard() are optimised. Patch by Antoine Pitrou. (Github issue #2042) + dict.pop() is optimised. Original patch by Antoine Pitrou. (Github issue #2047) + Iteration over sets and frozensets is optimised. (Github issue #2048) + Safe integer loops (< range(2^30)) are automatically optimised into C loops. + alist.extend([a,b,c]) is optimised into sequential list.append() calls for short literal sequences. + Calls to builtin methods that are not specifically optimised into C-API calls now use a cache that avoids repeated lookups of the underlying C function. (Github issue #2054) + Single argument function calls can avoid the argument tuple creation in some cases. + Some redundant extension type checks are avoided. + Formatting C enum values in f-strings is faster, as well as some other special cases. + String formatting with the '%' operator is optimised into f-strings in simple cases. + Subscripting (item access) is faster in some cases. + Some bytearray operations have been optimised similar to bytes. + Some PEP-484/526 container type declarations are now considered for loop optimisations. + Indexing into memoryview slices with view[i][j] is now optimised into view[i, j]. + Python compatible cython.* types can now be mixed with type declarations in Cython syntax. + Name lookups in the module and in classes are faster. + Python attribute lookups on extension types without instance dict are faster. + Some missing signals were added to libc/signal.pxd. Patch by Jeroen Demeyer. (Github issue #1914) + The warning about repeated extern declarations is now visible by default. (Github issue #1874) + The exception handling of the function types used by CPython's type slot functions was corrected to match the de-facto standard behaviour, so that code that uses them directly benefits from automatic and correct exception propagation. Patch by Jeroen Demeyer. (Github issue #1980) + Defining the macro CYTHON_NO_PYINIT_EXPORT will prevent the module init function from being exported as symbol, e.g. when linking modules statically in an embedding setup. Patch by AraHaan. (Github issue #1944) * Bugs fixed + If a module name is explicitly provided for an Extension() that is compiled via cythonize(), it was previously ignored and replaced by the source file name. It can now be used to override the target module name, e.g. for compiling prefixed accelerator modules from Python files. (Github issue #2038) + The arguments of the num_threads parameter of parallel sections were not sufficiently validated and could lead to invalid C code. (Github issue #1957) + Catching exceptions with a non-trivial exception pattern could call into CPython with a live exception set. This triggered incorrect behaviour and crashes, especially in CPython 3.7. + The signature of the special __richcmp__() method was corrected to recognise the type of the first argument as self. It was previously treated as plain object, but CPython actually guarantees that it always has the correct type. Note: this can change the semantics of user code that previously relied on self being untyped. + Some Python 3 exceptions were not recognised as builtins when running Cython under Python 2. + Some async helper functions were not defined in the generated C code when compiling simple async code. (Github issue #2075) + Line tracing did not include generators and coroutines. (Github issue #1949) + C++ declarations for unordered_map were corrected. Patch by Michael Schatzow. (Github issue #1484) + Iterator declarations in C++ deque and vector were corrected. Patch by Alex Huszagh. (Github issue #1870) + The const modifiers in the C++ string declarations were corrected, together with the coercion behaviour of string literals into C++ strings. (Github issue #2132) + Some declaration types in libc.limits were corrected. Patch by Jeroen Demeyer. (Github issue #2016) + @cython.final was not accepted on Python classes with an @cython.cclass decorator. (Github issue #2040) + Cython no longer creates useless and incorrect PyInstanceMethod wrappers for methods in Python 3. Patch by Jeroen Demeyer. (Github issue #2105) + The builtin bytearray type could not be used as base type of cdef classes.

The new build_ext is available as ``new_build_ext``. ------------------------------------------------------------------- Wed Oct 26 14:55:49 UTC 2016 - toddrme2178@gmail.com - Fix source URL. ------------------------------------------------------------------- Wed Oct 26 01:36:12 UTC 2016 - toddrme2178@gmail.com - update to version 0.25: + Features added * def/cpdef methods of cdef classes benefit from Cython's internal function implementation, which enables introspection and line profiling for them. Implementation sponsored by Turbostream (www.turbostream-cfd.com). * The distutils extension ``Cython.Distutils.build_ext`` has now been updated to use cythonize which properly handles dependencies. The old extension can still be found in ``Cython.Distutils.old_build_ext`` and is now deprecated. * Calls to Python functions are faster, following the recent "FastCall" optimisations that Victor Stinner implemented for CPython 3.6. See https://bugs.python.org/issue27128 and related issues. * The new METH_FASTCALL calling convention for PyCFunctions is supported in CPython 3.6. See https://bugs.python.org/issue27810 * C++ classes can now have typedef members. STL containers updated with value_type. * Support for bazel using a the pyx_library rule in //Tools:rules.bzl. * Initial support for using Cython modules in Pyston. Patch by Daetalus. * Dynamic Python attributes are allowed on cdef classes if an attribute ``cdef dict __dict__`` is declared in the class. Patch by empyrical. * Cython implemented C++ classes can make direct calls to base class methods. Patch by empyrical. * New directive ``cython.no_gc`` to fully disable GC for a cdef class. Patch by Claudio Freire. * Buffer variables are no longer excluded from ``locals()``. Patch by da-woods. * Building f-strings is faster, especially when formatting C integers. * for-loop iteration over "std::string". * ``libc/math.pxd`` provides ``e`` and ``pi`` as alias constants to simplify usage as a drop-in replacement for Python's math module. * Speed up cython.inline(). * Binary lshift operations with small constant Python integers are faster. * Some integer operations on Python long objects are faster in Python 2.7. * Support for the C++ ``typeid`` operator. + Significant Bugs fixed * Division of complex numbers avoids overflow by using Smith's method. * Some function signatures in ``libc.math`` and ``numpy.pxd`` were incorrect. Pach by Michael Seifert. + Other changes * The "%%cython" IPython/jupyter magic now defaults to the language level of the current jupyter kernel. The language level can be set explicitly with "%%cython -2" or "%%cython -3". - update to version 0.24.1: * IPython cell magic was lacking a good way to enable Python 3 code semantics. It can now be used as "%%cython -3". * Follow a recent change in PEP 492 and CPython 3.5.1 that now requires the __aiter__() method of asynchronous iterators to be a simple def method instead of an async def method. * Coroutines and generators were lacking the __module__ special attribute. * C++ std::complex values failed to auto-convert from and to Python complex objects. * Namespaced C++ types could not be used as memory view types due to lack of name mangling. Patch by Ivan Smirnov. * Assignments between identical C++ types that were declared with differently typedefed template types could fail. * Rebuilds could fail to evaluate dependency timestamps in C++ mode. Patch by Ian Henriksen. * Macros defined in the distutils compiler option do not require values anymore. Patch by Ian Henriksen. * Minor fixes for MSVC, Cygwin and PyPy. - specfile: * changed to https for source url * updated source url to files.pythonhosted.org - update to version 0.24: * Features added + PEP 498: Literal String Formatting (f-strings). Original patch by Jelle Zijlstra. https://www.python.org/dev/peps/pep-0498/ + PEP 515: Underscores as visual separators in number literals. https://www.python.org/dev/peps/pep-0515/ + Parser was adapted to some minor syntax changes in Py3.6, e.g. https://bugs.python.org/issue9232 + The embedded C code comments that show the original source code can be discarded with the new directive emit_code_comments=False. + Cpdef enums are now first-class iterable, callable types in Python. + Ctuples can now be declared in pure Python code. + Posix declarations for DLL loading and stdio extensions were added. Patch by Lars Buitinck. + The Py2-only builtins unicode(), xrange(), reduce() and long are now also available in compile time DEF expressions when compiling with Py3. + Exception type tests have slightly lower overhead. This fixes ticket 868. + @property syntax fully supported in cdef classes, old syntax deprecated. + C++ classes can now be declared with default template parameters. * Bugs fixed + C++ exceptions raised by overloaded C++ operators were not always handled. Patch by Ian Henriksen. + C string literals were previously always stored as non-const global variables in the module. They are now stored as global constants when possible, and otherwise as non-const C string literals in the generated code that uses them. This improves compatibility with strict C compiler options and prevents non-const strings literals with the same content from being incorrectly merged. + Compile time evaluated str expressions (DEF) now behave in a more useful way by turning into Unicode strings when compiling under Python 3. This allows using them as intermediate values in expressions. Previously, they always evaluated to bytes objects. + isinf() declarations in libc/math.pxd and numpy/math.pxd now reflect the actual tristate int return value instead of using bint. + Literal assignments to ctuples avoid Python tuple round-trips in some more corner cases. + Iteration over dict(...).items() failed to get optimised when dict arguments included keyword arguments. + cProfile now correctly profiles cpdef functions and methods. - update to version 0.23.5: * Compile errors and warnings in integer type conversion code. This fixes ticket 877. Patches by Christian Neukirchen, Nikolaus Rath, Ian Henriksen. * Reference leak when "*args" argument was reassigned in closures. * Truth-testing Unicode strings could waste time and memory in Py3.3+. * Return values of async functions could be ignored and replaced by None. * Compiler crash in CPython 3.6. * Fix prange() to behave identically to range(). The end condition was miscalculated when the range was not exactly divisible by the step. * Optimised all(genexpr)/any(genexpr) calls could warn about unused code. This fixes ticket 876. - Remove unneeded python-Cython-c++11.patch ------------------------------------------------------------------- Mon Feb 1 10:30:06 UTC 2016 - toddrme2178@gmail.com - update to version 0.23.4: * Memory leak when calling Python functions in PyPy. * Compilation problem with MSVC in C99-ish mode. * Warning about unused values in a helper macro. - update to version 0.23.3: * Invalid C code for some builtin methods. This fixes ticket 856 again. * Incorrect C code in helper functions for PyLong conversion and string decoding. This fixes ticket 863, ticket 864 and ticket 865. Original patch by Nikolaus Rath. * Large folded or inserted integer constants could use too small C integer types and thus trigger a value wrap-around. * The coroutine and generator types of Cython now also register directly with the Coroutine and Generator ABCs in the backports_abc module if it can be imported. This fixes ticket 870. - update to version 0.23.2: * Compiler crash when analysing some optimised expressions. * Coverage plugin was adapted to coverage.py 4.0 beta 2. * C++ destructor calls could fail when '&' operator is overwritten. * Incorrect C literal generation for large integers in compile-time evaluated DEF expressions and constant folded expressions. * Byte string constants could end up as Unicode strings when originating from compile-time evaluated DEF expressions. * Invalid C code when caching known builtin methods. This fixes ticket 860. * ino_t in posix.types was not declared as unsigned. * Declarations in libcpp/memory.pxd were missing operator!(). Patch by Leo Razoumov. * Static cdef methods can now be declared in .pxd files. - update to version 0.23.1: * Invalid C code for generators. This fixes ticket 858. * Invalid C code for some builtin methods. This fixes ticket 856. * Invalid C code for unused local buffer variables. This fixes ticket 154. * Test failures on 32bit systems. This fixes ticket 857. * Code that uses "from xyz import *" and global C struct/union/array variables could fail to compile due to missing helper functions. This fixes ticket 851. * Misnamed PEP 492 coroutine property cr_yieldfrom renamed to cr_await to match CPython. * Missing deallocation code for C++ object attributes in certain extension class hierarchies. * Crash when async coroutine was not awaited. * Compiler crash on yield in signature annotations and default argument values. Both are forbidden now. * Compiler crash on certain constructs in finally clauses. * Cython failed to build when CPython's pgen is installed. - 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.

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. Bugs fixed * 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. Other changes * 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. ------------------------------------------------------------------- Thu Feb 5 11:35:45 UTC 2015 - hpj@urpla.net - fix update-alternatives handling in a distribution backwards compatible way ------------------------------------------------------------------- Fri Jan 9 15:20:31 UTC 2015 - dimstar@opensuse.org - Re-enable test-suite. - Add gcc-c++ BuildRequires: needed for the test-suite to be able to pass. ------------------------------------------------------------------- Thu Jan 8 12:22:10 UTC 2015 - dimstar@opensuse.org - Fix usage of update-alternatives. ------------------------------------------------------------------- Thu Dec 18 10:48:28 UTC 2014 - p.drouand@gmail.com - Improve update-alternatives. - Remove 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 22:57:00 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. ------------------------------------------------------------------- Thu Jul 31 16:26:07 UTC 2014 - dimstar@opensuse.org - Rename rpmlintrc to %{name}-rpmlintrc. Follow the packaging guidelines. ------------------------------------------------------------------- Thu Jul 24 05:32:47 UTC 2014 - mcihar@suse.cz - Update to version 0.20.2: * Some optimisations for set/frozenset instantiation. * Support for C++ unordered_set and unordered_map. * 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 disabled 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. - add python-xml to build requirements for testsuite ------------------------------------------------------------------- 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. ------------------------------------------------------------------- Mon Feb 3 18:51:50 UTC 2014 - jengelh@inai.de - Cython grew a dependency on saxutils (and since then, libplist failed to build). Add python-xml as a Requires to avoid: [...] File "/usr/lib64/python2.7/site-packages/Cython/Compiler/Annotate.py", line 6, in <module> from xml.sax.saxutils import escape as html_escape. ImportError: No module named xml.sax.saxutils ------------------------------------------------------------------- Fri Jan 31 10:19:40 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. ------------------------------------------------------------------- Mon Oct 21 12:13:57 UTC 2013 - dmueller@suse.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 17:06:20 UTC 2013 - p.drouand@gmail.com - Implement update-alternatives ------------------------------------------------------------------- Mon May 13 08:17:40 UTC 2013 - dmueller@suse.com - update to 0.19.1: * Completely empty C-API structs for extension type slots (protocols like number/mapping/sequence) are no longer generated into the C code. * Docstrings that directly follow a public/readonly attribute declaration in a cdef class will be used as docstring of the auto-generated property. This fixes ticket 206. * The automatic signature documentation tries to preserve more semantics of default arguments and argument types. Specifically, bint arguments now appear as type bool. * A warning is emitted when negative literal indices are found inside of a code section that disables wraparound handling. This helps with fixing invalid code that might fail in the face of future compiler optimisations. * Constant folding for boolean expressions (and/or) was improved. * Added a build_dir option to cythonize() which allows one to place the generated .c files outside the source tree. ------------------------------------------------------------------- Mon Apr 29 11:58:41 UTC 2013 - dmueller@suse.com - Update to version 0.19: + Please see http://wiki.cython.org/ReleaseNotes-0.19 ------------------------------------------------------------------- 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 ------------------------------------------------------------------- Thu Nov 22 15:32:14 UTC 2012 - saschpe@suse.de - Update to version 0.17.2: + Please see http://wiki.cython.org/ReleaseNotes-0.17.2 - Drop excessive macro usage - No need for "-fno-strict-aliasing" anymore - One rpmlintrc is enough ------------------------------------------------------------------- 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 ------------------------------------------------------------------- Mon Apr 23 11:09:29 UTC 2012 - vdziewiecki@suse.com -Update to 0.16: http://wiki.cython.org/ReleaseNotes-0.16 ------------------------------------------------------------------- Wed Feb 29 19:07:57 UTC 2012 - pascal.bleser@opensuse.org - add rpmlintrc to mask false positives ------------------------------------------------------------------- Wed Sep 21 12:34:19 UTC 2011 - saschpe@suse.de - Update to version 0.15.1: * Please see http://wiki.cython.org/ReleaseNotes-0.15.1 ------------------------------------------------------------------- Tue Sep 6 13:25:54 UTC 2011 - saschpe@suse.de - Add Provides/Obsoletes for python-cython ------------------------------------------------------------------- Fri Sep 2 11:03:40 UTC 2011 - saschpe@suse.de - Fixed a typo - Removed testsuite again, fixes SLE build ------------------------------------------------------------------- Fri Sep 2 09:50:25 UTC 2011 - saschpe@suse.de - Update to version 0.15: * For loop docs fix and pointer iteration. * Pure decorators now implemented. * fix bug #707: optimised dict iteration over non-trivial expressions fail... * optimise object.pop() for sets * Py2.4 fix: PySet_Pop() appeared in Py2.5 * Py3.3 test fix * Support module level control flow and Entry-level error on uninitialized - Spec file cleanup: - Fixed wrong EOL encodings and non-excutable scripts - Set license to Apache-2.0 - Run testsuite ------------------------------------------------------------------- Wed Apr 20 00:29:18 UTC 2011 - prusnak@opensuse.org - updated to 0.14.1 - changes too numerous to list, see the following for more details: * http://wiki.cython.org/ReleaseNotes-0.13 * http://wiki.cython.org/ReleaseNotes-0.14 * http://wiki.cython.org/ReleaseNotes-0.14.1 ------------------------------------------------------------------- Sun Jun 6 21:21:32 UTC 2010 - dimstar@opensuse.org - Use renewed python-macros, also for compatibility with other build targets. ------------------------------------------------------------------- Sun Jun 6 12:14:18 UTC 2010 - dimstar@opensuse.org - Initial package of Cython 0.12.1
