- update to version 0.29.1:180
* Bugs fixed181
+ Extensions compiled with MinGW-64 under Windows could182
misinterpret integer objects larger than 15 bit and return183
incorrect results. (Github issue #2670)184
+ Cython no longer requires the source to be writable when copying185
its data into a memory view slice. Patch by Andrey186
Paramonov. (Github issue #2644)187
+ Line tracing of try-statements generated invalid C code. (Github188
issue #2274)189
+ When using the warn.undeclared directive, Cython's own code190
generated warnings that are now fixed. Patch by Nicolas191
Pauss. (Github issue #2685)192
+ Cython's memoryviews no longer require strides for setting the193
shape field but only the PyBUF_ND flag to be set. Patch by John194
Kirkham. (Github issue #2716)195
+ Some C compiler warnings about unused memoryview code were196
fixed. Patch by Ho Cheuk Ting. (Github issue #2588)197
+ A C compiler warning about implicit signed/unsigned conversion198
was fixed. (Github issue #2729)199
+ Assignments to C++ references returned by operator[] could fail200
to compile. (Github issue #2671)201
+ The power operator and the support for NumPy math functions were202
fixed in Pythran expressions. Patch by Serge Guelton. (Github203
issues #2702, #2709)204
+ Signatures with memory view arguments now show the expected type205
when embedded in docstrings. Patch by Matthew Chan and Benjamin206
Weigel. (Github issue #2634)207
+ Some from ... cimport ... constructs were not correctly208
considered when searching modified dependencies in cythonize()209
to decide whether to recompile a module. Patch by Kryštof210
Pilnáček. (Github issue #2638)211
+ A struct field type in the cpython.array declarations was212

Wed Oct 17 15:29:49 UTC 2018 - Arun Persaud <arun@gmx.de>216
217
- update to version 0.29:218
* Features added219
+ PEP-489 multi-phase module initialisation has been enabled220
again. Module reloads in other subinterpreters raise an221
exception to prevent corruption of the static module state.222
+ A set of mypy compatible PEP-484 declarations were added for223
Cython's C data types to integrate with static analysers in224
typed Python code. They are available in the Cython/Shadow.pyi225
module and describe the types in the special cython module that226
can be used for typing in Python code. Original patch by Julian227
Gethmann. (Github issue #1965)228
+ Memoryviews are supported in PEP-484/526 style type229
declarations. (Github issue #2529)230
+ @cython.nogil is supported as a C-function decorator in Python231
code. (Github issue #2557)232
+ Raising exceptions from nogil code will automatically acquire233
the GIL, instead of requiring an explicit with gil block.234
+ C++ functions can now be declared as potentially raising both235
C++ and Python exceptions, so that Cython can handle both236
correctly. (Github issue #2615)237
+ cython.inline() supports a direct language_level keyword238
argument that was previously only available via a directive.239
+ A new language level name 3str was added that mostly corresponds240
to language level 3, but keeps unprefixed string literals as241
type 'str' in both Py2 and Py3, and the builtin 'str' type242
unchanged. This will become the default in the next Cython243
release and is meant to help user code a) transition more easily244
to this new default and b) migrate to Python 3 source code245
semantics without making support for Python 2.x difficult.246
+ In CPython 3.6 and later, looking up globals in the module dict247
is almost as fast as looking up C globals. (Github issue #2313)248
+ For a Python subclass of an extension type, repeated method249
calls to non-overridden cpdef methods can avoid the attribute250
lookup in Py3.6+, which makes them 4x faster. (Github issue251
#2313)252
+ (In-)equality comparisons of objects to integer literals are253
faster. (Github issue #2188)254
+ Some internal and 1-argument method calls are faster.255
+ Modules that cimport many external extension types from other256
Cython modules execute less import requests during module257
initialisation.258
+ Constant tuples and slices are deduplicated and only created259
once per module. (Github issue #2292)260
+ The coverage plugin considers more C file extensions such as .cc261
and .cxx. (Github issue #2266)262
+ The cythonize command accepts compile time variable values (as263
set by DEF) through the new -E option. Patch by Jerome264
Kieffer. (Github issue #2315)265
+ pyximport can import from namespace packages. Patch by Prakhar266
Goel. (Github issue #2294)267
+ Some missing numpy and CPython C-API declarations were268
added. Patch by John Kirkham. (Github issues #2523, #2520,269
#2537)270
+ Declarations for the pylifecycle C-API functions were added in a271
new .pxd file cpython.pylifecycle.272
+ The Pythran support was updated to work with the latest Pythran273
0.8.7. Original patch by Adrien Guinet. (Github issue #2600)274
+ %a is included in the string formatting types that are optimised275
into f-strings. In this case, it is also automatically mapped276
to %r in Python 2.x.277
+ New C macro CYTHON_HEX_VERSION to access Cython's version in the278
same style as PY_HEX_VERSION.279
+ Constants in libc.math are now declared as const to simplify280
their handling.281
+ An additional check_size clause was added to the ctypedef class282
name specification to allow suppressing warnings when importing283
modules with backwards-compatible PyTypeObject size284
changes. Patch by Matti Picus. (Github issue #2627)285
* Bugs fixed286
+ The exception handling in generators and coroutines under287
CPython 3.7 was adapted to the newly introduced exception288
stack. Users of Cython 0.28 who want to support Python 3.7 are289
encouraged to upgrade to 0.29 to avoid potentially incorrect290
error reporting and tracebacks. (Github issue #1958)291
+ Crash when importing a module under Stackless Python that was292
built for CPython. Patch by Anselm Kruis. (Github issue #2534)293
+ 2-value slicing of typed sequences failed if the start or stop294
index was None. Patch by Christian Gibson. (Github issue #2508)295
+ Multiplied string literals lost their factor when they are part296
of another constant expression (e.g. 'x' * 10 + 'y' => 'xy').297
+ String formatting with the '%' operator didn't call the special298
__rmod__() method if the right side is a string subclass that299
implements it. (Python issue 28598)300
+ The directive language_level=3 did not apply to the first token301
in the source file. (Github issue #2230)302
+ Overriding cpdef methods did not work in Python subclasses with303
slots. Note that this can have a performance impact on calls304
from Cython code. (Github issue #1771)305
+ Fix declarations of builtin or C types using strings in pure306
python mode. (Github issue #2046)307
+ Generator expressions and lambdas failed to compile in @cfunc308
functions. (Github issue #459)309
+ Global names with const types were not excluded from star-import310
assignments which could lead to invalid C code. (Github issue311
#2621)312
+ Several internal function signatures were fixed that lead to313
warnings in gcc-8. (Github issue #2363)314
+ The numpy helper functions set_array_base() and get_array_base()315
were adapted to the current numpy C-API recommendations. Patch316
by Matti Picus. (Github issue #2528)317
+ Some NumPy related code was updated to avoid deprecated API318
usage. Original patch by jbrockmendel. (Github issue #2559)319
+ Several C++ STL declarations were extended and corrected. Patch320
by Valentin Valls. (Github issue #2207)321
+ C lines of the module init function were unconditionally not322
reported in exception stack traces. Patch by Jeroen323
Demeyer. (Github issue #2492)324
+ When PEP-489 support is enabled, reloading the module overwrote325
any static module state. It now raises an exception instead,326
given that reloading is not actually supported.327
+ Object-returning, C++ exception throwing functions were not328
checking that the return value was non-null. Original patch by329
Matt Wozniski (Github Issue #2603)330
+ The source file encoding detection could get confused if the331
c_string_encoding directive appeared within the first two332
lines. (Github issue #2632)333
+ Cython generated modules no longer emit a warning during import334
when the size of the NumPy array type is larger than what was335
found at compile time. Instead, this is assumed to be a336
backwards compatible change on NumPy side.337
* Other changes338
+ Cython now emits a warning when no language_level (2, 3 or339
'3str') is set explicitly, neither as a cythonize() option nor340
as a compiler directive. This is meant to prepare the transition341
of the default language level from currently Py2 to Py3, since342
that is what most new users will expect these days. The future343
default will, however, not enforce unicode literals, because344
this has proven a major obstacle in the support for both Python345
2.x and 3.x. The next major release is intended to make this346
change, so that it will parse all code that does not request a347
specific language level as Python 3 code, but with str348
literals. The language level 2 will continue to be supported for349
an indefinite time.350
+ The documentation was restructured, cleaned up and examples are351
now tested. The NumPy tutorial was also rewritten to simplify352
the running example. Contributed by Gabriel de353
Marmiesse. (Github issue #2245)354
+ Cython compiles less of its own modules at build time to reduce355
the installed package size to about half of its previous356
size. This makes the compiler slightly slower, by about 5-7%.357

``libcpp.string``. Patch by Alex Huszagh. (Github issue #2123)399
* The C++11 methods ``reserve()`` and ``bucket_count()`` are declared for400
``std::unordered_map``. Patch by Valentin Valls. (Github issue #2168)401
+ Bugs fixed402
* The copy of a read-only memoryview was considered read-only as well, whereas403
a common reason to copy a read-only view is to make it writable. The result404
of the copying is now a writable buffer by default.405
(Github issue #2134)406
* The ``switch`` statement generation failed to apply recursively to the body of407
converted if-statements.408
* ``NULL`` was sometimes rejected as exception return value when the returned409
type is a fused pointer type.410
Patch by Callie LeFave. (Github issue #2177)411
* Fixed compatibility with PyPy 5.11.412
Patch by Matti Picus. (Github issue #2165)413

when the templates mix const with ctypedef. (Github issue #2148)426
* Undeclared C++ no-args constructors in subclasses could make the427
compilation fail if the base class constructor was declared without428
nogil. (Github issue #2157)429
* Bytes %-formatting inferred basestring (bytes or unicode) as result type430
in some cases where bytes would have been safe to infer. (Github issue #2153)431

436
- update to version 0.28:437
* Features added438
+ Cdef classes can now multiply inherit from ordinary Python439
classes. (The primary base must still be a c class, possibly440
object, and the other bases must not be cdef classes.)441
+ Type inference is now supported for Pythran compiled NumPy442
expressions. Patch by Nils Braun. (Github issue #1954)443
+ The const modifier can be applied to memoryview declarations to444
allow read-only buffers as input. (Github issues #1605, #1869)445
+ C code in the docstring of a cdef extern block is copied446
verbatimly into the generated file. Patch by Jeroen447
Demeyer. (Github issue #1915)448
+ When compiling with gcc, the module init function is now tuned449
for small code size instead of whatever compile flags were450
provided externally. Cython now also disables some code451
intensive optimisations in that function to further reduce the452
code size. (Github issue #2102)453
+ Decorating an async coroutine with @cython.iterable_coroutine454
changes its type at compile time to make it iterable. While this455
is not strictly in line with PEP-492, it improves the456
interoperability with old-style coroutines that use yield from457
instead of await.458
+ The IPython magic has preliminary support for459
JupyterLab. (Github issue #1775)460
+ The new TSS C-API in CPython 3.7 is supported and has been461
backported. Patch by Naotoshi Seo. (Github issue #1932)462
+ Cython knows the new Py_tss_t type defined in PEP-539 and463
automatically initialises variables declared with that type to464
Py_tss_NEEDS_INIT, a value which cannot be used outside of465
static assignments.466
+ The set methods .remove() and .discard() are optimised. Patch by467
Antoine Pitrou. (Github issue #2042)468
+ dict.pop() is optimised. Original patch by Antoine469
Pitrou. (Github issue #2047)470
+ Iteration over sets and frozensets is optimised. (Github issue471
#2048)472
+ Safe integer loops (< range(2^30)) are automatically optimised473
into C loops.474
+ alist.extend([a,b,c]) is optimised into sequential list.append()475
calls for short literal sequences.476
+ Calls to builtin methods that are not specifically optimised477
into C-API calls now use a cache that avoids repeated lookups of478
the underlying C function. (Github issue #2054)479
+ Single argument function calls can avoid the argument tuple480
creation in some cases.481
+ Some redundant extension type checks are avoided.482
+ Formatting C enum values in f-strings is faster, as well as some483
other special cases.484
+ String formatting with the '%' operator is optimised into485
f-strings in simple cases.486
+ Subscripting (item access) is faster in some cases.487
+ Some bytearray operations have been optimised similar to bytes.488
+ Some PEP-484/526 container type declarations are now considered489
for loop optimisations.490
+ Indexing into memoryview slices with view[i][j] is now optimised491
into view[i, j].492
+ Python compatible cython.* types can now be mixed with type493
declarations in Cython syntax.494
+ Name lookups in the module and in classes are faster.495
+ Python attribute lookups on extension types without instance496
dict are faster.497
+ Some missing signals were added to libc/signal.pxd. Patch by498
Jeroen Demeyer. (Github issue #1914)499
+ The warning about repeated extern declarations is now visible by500
default. (Github issue #1874)501
+ The exception handling of the function types used by CPython's502
type slot functions was corrected to match the de-facto standard503
behaviour, so that code that uses them directly benefits from504
automatic and correct exception propagation. Patch by Jeroen505
Demeyer. (Github issue #1980)506
+ Defining the macro CYTHON_NO_PYINIT_EXPORT will prevent the507
module init function from being exported as symbol, e.g. when508
linking modules statically in an embedding setup. Patch by509
AraHaan. (Github issue #1944)510
* Bugs fixed511
+ If a module name is explicitly provided for an Extension() that512
is compiled via cythonize(), it was previously ignored and513
replaced by the source file name. It can now be used to override514
the target module name, e.g. for compiling prefixed accelerator515
modules from Python files. (Github issue #2038)516
+ The arguments of the num_threads parameter of parallel sections517
were not sufficiently validated and could lead to invalid C518
code. (Github issue #1957)519
+ Catching exceptions with a non-trivial exception pattern could520
call into CPython with a live exception set. This triggered521
incorrect behaviour and crashes, especially in CPython 3.7.522
+ The signature of the special __richcmp__() method was corrected523
to recognise the type of the first argument as self. It was524
previously treated as plain object, but CPython actually525
guarantees that it always has the correct type. Note: this can526
change the semantics of user code that previously relied on self527
being untyped.528
+ Some Python 3 exceptions were not recognised as builtins when529
running Cython under Python 2.530
+ Some async helper functions were not defined in the generated C531
code when compiling simple async code. (Github issue #2075)532
+ Line tracing did not include generators and coroutines. (Github533
issue #1949)534
+ C++ declarations for unordered_map were corrected. Patch by535
Michael Schatzow. (Github issue #1484)536
+ Iterator declarations in C++ deque and vector were537
corrected. Patch by Alex Huszagh. (Github issue #1870)538
+ The const modifiers in the C++ string declarations were539
corrected, together with the coercion behaviour of string540
literals into C++ strings. (Github issue #2132)541
+ Some declaration types in libc.limits were corrected. Patch by542
Jeroen Demeyer. (Github issue #2016)543
+ @cython.final was not accepted on Python classes with an544
@cython.cclass decorator. (Github issue #2040)545
+ Cython no longer creates useless and incorrect PyInstanceMethod546
wrappers for methods in Python 3. Patch by Jeroen547
Demeyer. (Github issue #2105)548
+ The builtin bytearray type could not be used as base type of549
cdef classes. (Github issue #2106)550

- update to version 0.25:595
+ Features added596
* def/cpdef methods of cdef classes benefit from Cython's internal function597
implementation, which enables introspection and line profiling for them.598
Implementation sponsored by Turbostream (www.turbostream-cfd.com).599
* The distutils extension ``Cython.Distutils.build_ext`` has now been updated600
to use cythonize which properly handles dependencies. The old extension can601
still be found in ``Cython.Distutils.old_build_ext`` and is now deprecated.602
* Calls to Python functions are faster, following the recent "FastCall"603
optimisations that Victor Stinner implemented for CPython 3.6.604
See https://bugs.python.org/issue27128 and related issues.605
* The new METH_FASTCALL calling convention for PyCFunctions is supported606
in CPython 3.6. See https://bugs.python.org/issue27810607
* C++ classes can now have typedef members. STL containers updated with608
value_type.609
* Support for bazel using a the pyx_library rule in //Tools:rules.bzl.610
* Initial support for using Cython modules in Pyston. Patch by Daetalus.611
* Dynamic Python attributes are allowed on cdef classes if an attribute612
``cdef dict __dict__`` is declared in the class. Patch by empyrical.613
* Cython implemented C++ classes can make direct calls to base class methods.614
Patch by empyrical.615
* New directive ``cython.no_gc`` to fully disable GC for a cdef class.616
Patch by Claudio Freire.617
* Buffer variables are no longer excluded from ``locals()``.618
Patch by da-woods.619
* Building f-strings is faster, especially when formatting C integers.620
* for-loop iteration over "std::string".621
* ``libc/math.pxd`` provides ``e`` and ``pi`` as alias constants to simplify622
usage as a drop-in replacement for Python's math module.623
* Speed up cython.inline().624
* Binary lshift operations with small constant Python integers are faster.625
* Some integer operations on Python long objects are faster in Python 2.7.626
* Support for the C++ ``typeid`` operator.627
+ Significant Bugs fixed628
* Division of complex numbers avoids overflow by using Smith's method.629
* Some function signatures in ``libc.math`` and ``numpy.pxd`` were incorrect.630
Pach by Michael Seifert.631
+ Other changes632
* The "%%cython" IPython/jupyter magic now defaults to the language level of633
the current jupyter kernel. The language level can be set explicitly with634
"%%cython -2" or "%%cython -3".635
- update to version 0.24.1:636
* IPython cell magic was lacking a good way to enable Python 3 code637
semantics. It can now be used as "%%cython -3".638
* Follow a recent change in PEP 492 and CPython 3.5.1 that now639
requires the __aiter__() method of asynchronous iterators to be a640
simple def method instead of an async def method.641
* Coroutines and generators were lacking the __module__ special642
attribute.643
* C++ std::complex values failed to auto-convert from and to Python644
complex objects.645
* Namespaced C++ types could not be used as memory view types due to646
lack of name mangling. Patch by Ivan Smirnov.647
* Assignments between identical C++ types that were declared with648
differently typedefed template types could fail.649
* Rebuilds could fail to evaluate dependency timestamps in C++650
mode. Patch by Ian Henriksen.651
* Macros defined in the distutils compiler option do not require652
values anymore. Patch by Ian Henriksen.653
* Minor fixes for MSVC, Cygwin and PyPy.654
- specfile:655
* changed to https for source url656
* updated source url to files.pythonhosted.org657
- update to version 0.24:658
* Features added659
+ PEP 498: Literal String Formatting (f-strings). Original patch660
by Jelle Zijlstra. https://www.python.org/dev/peps/pep-0498/661
+ PEP 515: Underscores as visual separators in number662
literals. https://www.python.org/dev/peps/pep-0515/663
+ Parser was adapted to some minor syntax changes in Py3.6,664
e.g. https://bugs.python.org/issue9232665
+ The embedded C code comments that show the original source code666
can be discarded with the new directive667
emit_code_comments=False.668
+ Cpdef enums are now first-class iterable, callable types in669
Python.670
+ Ctuples can now be declared in pure Python code.671
+ Posix declarations for DLL loading and stdio extensions were672
added. Patch by Lars Buitinck.673
+ The Py2-only builtins unicode(), xrange(), reduce() and long are674
now also available in compile time DEF expressions when675
compiling with Py3.676
+ Exception type tests have slightly lower overhead. This fixes677
ticket 868.678
+ @property syntax fully supported in cdef classes, old syntax679
deprecated.680
+ C++ classes can now be declared with default template681
parameters.682
* Bugs fixed683
+ C++ exceptions raised by overloaded C++ operators were not684
always handled. Patch by Ian Henriksen.685
+ C string literals were previously always stored as non-const686
global variables in the module. They are now stored as global687
constants when possible, and otherwise as non-const C string688
literals in the generated code that uses them. This improves689
compatibility with strict C compiler options and prevents690
non-const strings literals with the same content from being691
incorrectly merged.692
+ Compile time evaluated str expressions (DEF) now behave in a693
more useful way by turning into Unicode strings when compiling694
under Python 3. This allows using them as intermediate values in695
expressions. Previously, they always evaluated to bytes objects.696
+ isinf() declarations in libc/math.pxd and numpy/math.pxd now697
reflect the actual tristate int return value instead of using698
bint.699
+ Literal assignments to ctuples avoid Python tuple round-trips in700
some more corner cases.701
+ Iteration over dict(...).items() failed to get optimised when702
dict arguments included keyword arguments.703
+ cProfile now correctly profiles cpdef functions and methods.704
- update to version 0.23.5:705
* Compile errors and warnings in integer type conversion code. This706
fixes ticket 877. Patches by Christian Neukirchen, Nikolaus Rath,707
Ian Henriksen.708
* Reference leak when "*args" argument was reassigned in closures.709
* Truth-testing Unicode strings could waste time and memory in710
Py3.3+.711
* Return values of async functions could be ignored and replaced by712
None.713
* Compiler crash in CPython 3.6.714
* Fix prange() to behave identically to range(). The end condition715
was miscalculated when the range was not exactly divisible by the716
step.717
* Optimised all(genexpr)/any(genexpr) calls could warn about unused718
code. This fixes ticket 876.719
- Remove unneeded python-Cython-c++11.patch720
721
-------------------------------------------------------------------722
Mon Feb 1 10:30:06 UTC 2016 - toddrme2178@gmail.com723
724
- update to version 0.23.4:725
* Memory leak when calling Python functions in PyPy.726
* Compilation problem with MSVC in C99-ish mode.727
* Warning about unused values in a helper macro.728
- update to version 0.23.3:729
* Invalid C code for some builtin methods. This fixes ticket 856730
again.731
* Incorrect C code in helper functions for PyLong conversion and732
string decoding. This fixes ticket 863, ticket 864 and ticket733
865. Original patch by Nikolaus Rath.734
* Large folded or inserted integer constants could use too small C735
integer types and thus trigger a value wrap-around.736
* The coroutine and generator types of Cython now also register737
directly with the Coroutine and Generator ABCs in the738
backports_abc module if it can be imported. This fixes ticket 870.739
- update to version 0.23.2:740
* Compiler crash when analysing some optimised expressions.741
* Coverage plugin was adapted to coverage.py 4.0 beta 2.742
* C++ destructor calls could fail when '&' operator is overwritten.743
* Incorrect C literal generation for large integers in compile-time744
evaluated DEF expressions and constant folded expressions.745
* Byte string constants could end up as Unicode strings when746
originating from compile-time evaluated DEF expressions.747
* Invalid C code when caching known builtin methods. This fixes748
ticket 860.749
* ino_t in posix.types was not declared as unsigned.750
* Declarations in libcpp/memory.pxd were missing operator!(). Patch751
by Leo Razoumov.752
* Static cdef methods can now be declared in .pxd files.753
- update to version 0.23.1:754
* Invalid C code for generators. This fixes ticket 858.755
* Invalid C code for some builtin methods. This fixes ticket 856.756
* Invalid C code for unused local buffer variables. This fixes757
ticket 154.758
* Test failures on 32bit systems. This fixes ticket 857.759
* Code that uses "from xyz import *" and global C struct/union/array760
variables could fail to compile due to missing helper761
functions. This fixes ticket 851.762
* Misnamed PEP 492 coroutine property cr_yieldfrom renamed to763
cr_await to match CPython.764
* Missing deallocation code for C++ object attributes in certain765
extension class hierarchies.766
* Crash when async coroutine was not awaited.767
* Compiler crash on yield in signature annotations and default768
argument values. Both are forbidden now.769
* Compiler crash on certain constructs in finally clauses.770
* Cython failed to build when CPython's pgen is installed.771
- update to version 0.23:772
* Features added773
+ PEP 492 (async/await) was implemented. See774
https://www.python.org/dev/peps/pep-0492/775
+ PEP 448 (Additional Unpacking Generalizations) was776
implemented. See https://www.python.org/dev/peps/pep-0448/777
+ Support for coverage.py 4.0+ can be enabled by adding the plugin778
"Cython.Coverage" to the ".coveragerc" config file.779
+ Annotated HTML source pages can integrate (XML) coverage780
reports.781
+ Tracing is supported in nogil functions/sections and module init782
code.783
+ When generators are used in a Cython module and the module784
imports the modules "inspect" and/or "asyncio", Cython enables785
interoperability by patching these modules during the import to786
recognise Cython's internal generator and coroutine types. This787
can be disabled by C compiling the module with "-D788
CYTHON_PATCH_ASYNCIO=0" or "-D CYTHON_PATCH_INSPECT=0"789
+ When generators or coroutines are used in a Cython module, their790
types are registered with the Generator and Coroutine ABCs in791
the collections or collections.abc stdlib module at import time792
to enable interoperability with code that needs to detect and793
process Python generators/coroutines. These ABCs were added in794
CPython 3.5 and are available for older Python versions through795
the backports_abc module on PyPI. See796
https://bugs.python.org/issue24018797
+ Adding/subtracting/dividing/modulus and equality comparisons798
with constant Python floats and small integers are faster.799
+ Binary and/or/xor/rshift operations with small constant Python800
integers are faster.801
+ When called on generator expressions, the builtins all(), any(),802
dict(), list(), set(), sorted() and unicode.join() avoid the803
generator iteration overhead by inlining a part of their804
functionality into the for-loop.805
+ Keyword argument dicts are no longer copied on function entry806
when they are not being used or only passed through to other807
function calls (e.g. in wrapper functions).808
+ The PyTypeObject declaration in cpython.object was extended.809
+ The builtin type type is now declared as PyTypeObject in source,810
allowing for extern functions taking type parameters to have the811
correct C signatures. Note that this might break code that uses812
type just for passing around Python types in typed813
variables. Removing the type declaration provides a backwards814
compatible fix.815
+ wraparound() and boundscheck() are available as no-ops in pure816
Python mode.817
+ Const iterators were added to the provided C++ STL declarations.818
+ Smart pointers were added to the provided C++ STL819
declarations. Patch by Daniel Filonik.820
+ NULL is allowed as default argument when embedding821
signatures. This fixes ticket 843.822
+ When compiling with --embed, the internal module name is changed823
to __main__ to allow arbitrary program names, including those824
that would be invalid for modules. Note that this prevents reuse825
of the generated C code as an importable module.826
+ External C++ classes that overload the assignment operator can827
be used. Patch by Ian Henriksen.828
+ Support operator bool() for C++ classes so they can be used in829
if statements.830
* Bugs fixed831
+ Calling "yield from" from Python on a Cython generator that832
returned a value triggered a crash in CPython. This is now being833
worked around. See https://bugs.python.org/issue23996834
+ Language level 3 did not enable true division (a.k.a. float835
division) for integer operands.836
+ Functions with fused argument types that included a generic837
'object' fallback could end up using that fallback also for838
other explicitly listed object types.839
+ Relative cimports could accidentally fall back to trying an840
absolute cimport on failure.841
+ The result of calling a C struct constructor no longer requires842
an intermediate assignment when coercing to a Python dict.843
+ C++ exception declarations with mapping functions could fail to844
compile when pre-declared in .pxd files.845
+ cpdef void methods are now permitted.846
+ abs(cint) could fail to compile in MSVC and used sub-optimal847
code in C++. Patch by David Vierra, original patch by Michael848
Enßlin.849
+ Buffer index calculations using index variables with small C850
integer types could overflow for large buffer sizes. Original851
patch by David Vierra.852
+ C unions use a saner way to coerce from and to Python dicts.853
+ When compiling a module foo.pyx, the directories in sys.path are854
no longer searched when looking for foo.pxd. Patch by Jeroen855
Demeyer.856
+ Memory leaks in the embedding main function were fixed. Original857
patch by Michael Enßlin.858
+ Some complex Python expressions could fail to compile inside of859
finally clauses.860
+ Unprefixed 'str' literals were not supported as C varargs861
arguments.862
+ Fixed type errors in conversion enum types to/from Python. Note863
that this imposes stricter correctness requirements on enum864
declarations.865
* Other changes866
+ Changed mangling scheme in header files generated by cdef api867
declarations.868
+ Installation under CPython 3.3+ no longer requires a pass of the869
2to3 tool. This also makes it possible to run Cython in Python870
3.3+ from a source checkout without installing it first. Patch871
by Petr Viktorin.872
+ jedi-typer.py (in Tools/) was extended and renamed to873
jedityper.py (to make it importable) and now works with and874
requires Jedi 0.9. Patch by Tzer-jen Wei.875

Features added954
* C functions can coerce to Python functions, which allows passing them955
around as callable objects.956
* C arrays can be assigned by value and auto-coerce from Python iterables957
and to Python lists (and tuples).958
* Extern C functions can now be declared as cpdef to export them to959
the module's Python namespace. Extern C functions in pxd files export960
their values to their own module, iff it exists.961
* Anonymous C tuple types can be declared as (ctype1, ctype2, ...).962
* PEP 479: turn accidental StopIteration exceptions that exit generators963
into a RuntimeError, activated with future import "generator_stop".964
See http://legacy.python.org/dev/peps/pep-0479/965
* Looping over ``reversed(range())`` is optimised in the same way as966
``range()``. Patch by Favian Contreras.967
Bugs fixed968
* Mismatching 'except' declarations on signatures in .pxd and .pyx files failed969
to produce a compile error.970
* Failure to find any files for the path pattern(s) passed into ``cythonize()``971
is now an error to more easily detect accidental typos.972
* The ``logaddexp`` family of functions in ``numpy.math`` now has correct973
declarations.974
* In Py2.6/7 and Py3.2, simple Cython memory views could accidentally be975
interpreted as non-contiguous by CPython, which could trigger a CPython976
bug when copying data from them, thus leading to data corruption.977
See CPython issues 12834 and 23349.978
Other changes979
* Preliminary support for defining the Cython language with a formal grammar.980
To try parsing your files against this grammar, use the --formal_grammar directive.981
Experimental.982
* ``_`` is no longer considered a cacheable builtin as it could interfere with983
gettext.984
* Cythonize-computed metadata now cached in the generated C files.985

- Improve update-alternatives.1007
- Remove Cython-fix-version-detection.patch 1008
(got fixed upstream)1009
- update to version 0.21.1:1010
* Features added1011
- New cythonize option -a to generate the annotated HTML source view.1012
- Missing C-API declarations in cpython.unicode were added.1013
- Passing language='c++' into cythonize() globally enables C++ mode1014
for all modules that were not passed as Extension objects1015
(i.e. only source files and file patterns).1016
- Py_hash_t is a known type (used in CPython for hash values).1017
- PySlice_*() C-API functions are available from the cpython.slice module.1018
- Allow arrays of C++ classes.1019
* Bugs fixed1020
- Reference leak for non-simple Python expressions in boolean and/or expressions.1021
- To fix a name collision and to reflect availability on host1022
platforms, standard C declarations [ clock(), time(), struct tm1023
and tm* functions ] were moved from posix/time.pxd to a new1024
libc/time.pxd. Patch by Charles Blake.1025
- Rerunning unmodified modules in IPython's cython support1026
failed. Patch by Matthias Bussonier.1027
- Casting C++ std::string to Python byte strings failed when1028
auto-decoding was enabled.1029
- Fatal exceptions in global module init code could lead to1030
crashes if the already created module was used later on1031
(e.g. through a stale reference in sys.modules or elsewhere).1032
- cythonize.py script was not installed on MS-Windows.1033
* Other changes1034
- Compilation no longer fails hard when unknown compilation1035
options are passed. Instead, it raises a warning and ignores1036
them (as it did silently before 0.21). This will be changed back1037
to an error in a future release.1038

1047
- Add Cython-fix-version-detection.patch1048
This is a patch from upstream that restores version information1049
whose removal is preventing several packages from correctly1050
detecting Cython's presence. It is already merged upstream and 1051
so should be in the next release.1052
Note that despite what upstream says, 1053
python-tables/python3-tables is NOT the only package affected by1054
this, which is why the patch is going here instead of 1055
python-tables/python3-tables.1056
python-bcolz/python3-bcolz is an example of another package1057
affected.1058

-------------------------------------------------------------------1060
Thu Sep 11 09:30:20 UTC 2014 - toddrme2178@gmail.com1061
1062
- Update to 0.21 (2014-09-10)1063
* Features added1064
* C (cdef) functions allow inner Python functions.1065
* Enums can now be declared as cpdef to export their values to1066
the module's Python namespace. Cpdef enums in pxd files export1067
their values to their own module, iff it exists.1068
* Allow @staticmethod decorator to declare static cdef methods.1069
This is especially useful for declaring "constructors" for1070
cdef classes that can take non-Python arguments.1071
* Taking a ``char*`` from a temporary Python string object is safer1072
in more cases and can be done inside of non-trivial expressions,1073
including arguments of a function call. A compile time error1074
is raised only when such a pointer is assigned to a variable and1075
would thus exceed the lifetime of the string itself.1076
* Generators have new properties ``__name__`` and ``__qualname__``1077
that provide the plain/qualified name of the generator function1078
(following CPython 3.5). See http://bugs.python.org/issue212051079
* The ``inline`` function modifier is available as a decorator1080
``@cython.inline`` in pure mode.1081
* When cygdb is run in a virtualenv, it enables the same virtualenv1082
inside of the debugger. Patch by Marc Abramowitz.1083
* PEP 465: dedicated infix operator for matrix multiplication (A @ B).1084
* HTML output of annotated code uses Pygments for code highlighting1085
and generally received a major overhaul by Matthias Bussonier.1086
* IPython magic support is now available directly from Cython with1087
the command "%load_ext cython". Cython code can directly be1088
executed in a cell when marked with "%%cython". Code analysis1089
is available with "%%cython -a". Patch by Martín Gaitán.1090
* Simple support for declaring Python object types in Python signature1091
annotations. Currently requires setting the compiler directive1092
``annotation_typing=True``.1093
* New directive ``use_switch`` (defaults to True) to optionally disable1094
the optimization of chained if statement to C switch statements.1095
* Defines dynamic_cast et al. in ``libcpp.cast`` and C++ heap data1096
structure operations in ``libcpp.algorithm``.1097
* Shipped header declarations in ``posix.*`` were extended to cover1098
more of the POSIX API. Patches by Lars Buitinck and Mark Peek.1099
* Optimizations1100
* Simple calls to C implemented Python functions/methods are faster.1101
This also speeds up many operations on builtins that Cython cannot1102
otherwise optimise.1103
* The "and"/"or" operators try to avoid unnecessary coercions of their1104
arguments. They now evaluate the truth value of each argument1105
independently and only coerce the final result of the whole expression1106
to the target type (e.g. the type on the left side of an assignment).1107
This also avoids reference counting overhead for Python values during1108
evaluation and generally improves the code flow in the generated C code.1109
* The Python expression "2 ** N" is optimised into bit shifting.1110
See http://bugs.python.org/issue214201111
* Cascaded assignments (a = b = ...) try to minimise the number of1112
type coercions.1113
* Calls to ``slice()`` are translated to a straight C-API call.1114
* Bugs fixed1115
* Crash when assigning memory views from ternary conditional expressions.1116
* Nested C++ templates could lead to unseparated ">>" characters being1117
generated into the C++ declarations, which older C++ compilers could1118
not parse.1119
* Sending SIGINT (Ctrl-C) during parallel cythonize() builds could1120
hang the child processes.1121
* No longer ignore local setup.cfg files for distutils in pyximport.1122
Patch by Martin Teichmann.1123
* Taking a ``char*`` from an indexed Python string generated unsafe1124
reference counting code.1125
* Set literals now create all of their items before trying to add them1126
to the set, following the behaviour in CPython. This makes a1127
difference in the rare case that the item creation has side effects1128
and some items are not hashable (or if hashing them has side effects,1129
too).1130
* Cython no longer generates the cross product of C functions for code1131
that uses memory views of fused types in function signatures (e.g.1132
``cdef func(floating[:] a, floating[:] b)``). This is considered the1133
expected behaviour by most users and was previously inconsistent with1134
other structured types like C arrays. Code that really wants all type1135
combinations can create the same fused memoryview type under different1136
names and use those in the signature to make it clear which types are1137
independent.1138
* Names that were unknown at compile time were looked up as builtins at1139
runtime but not as global module names. Trying both lookups helps with1140
globals() manipulation.1141
* Fixed stl container conversion for typedef element types.1142
* ``obj.pop(x)`` truncated large C integer values of x to ``Py_ssize_t``.1143
* ``__init__.pyc`` is recognised as marking a package directory1144
(in addition to .py, .pyx and .pxd).1145
* Syntax highlighting in ``cython-mode.el`` for Emacs no longer1146
incorrectly highlights keywords found as part of longer names.1147
* Correctly handle ``from cython.submodule cimport name``.1148
* Fix infinite recursion when using super with cpdef methods.1149
* No-args ``dir()`` was not guaranteed to return a sorted list.1150
* Other changes1151
* The header line in the generated C files no longer contains the1152
timestamp but only the Cython version that wrote it. This was1153
changed to make builds more reproducible.1154
* Removed support for CPython 2.4, 2.5 and 3.1.1155
* The licensing implications on the generated code were clarified1156
to avoid legal constraints for users.1157

* Support for C++ unordered_set and unordered_map.1170
* Access to attributes of optimised builtin methods (e.g.1171
``[].append.__name__``) could fail to compile.1172
* Memory leak when extension subtypes add a memory view as attribute1173
to those of the parent type without having Python object attributes1174
or a user provided dealloc method.1175
* Compiler crash on readonly properties in "binding" mode.1176
* Auto-encoding with ``c_string_encoding=ascii`` failed in Py3.3.1177
* Crash when subtyping freelist enabled Cython extension types with1178
Python classes that use ``__slots__``.1179
* Freelist usage is restricted to CPython to avoid problems with other1180
Python implementations.1181
* Memory leak in memory views when copying overlapping, contiguous slices.1182
* Format checking when requesting non-contiguous buffers from1183
``cython.array`` objects was disabled in Py3.1184
* C++ destructor calls in extension types could fail to compile in clang.1185
* Buffer format validation failed for sequences of strings in structs.1186

Thu May 8 11:40:51 UTC 2014 - toddrme2178@gmail.com1191
1192
- Update to version 0.20.11193
* List/Tuple literals multiplied by more than one factor were only multiplied1194
by the last factor instead of all.1195
* Lookups of special methods (specifically for context managers) could fail1196
in Python <= 2.6/3.1.1197
* Local variables were erroneously appended to the signature introspection1198
of Cython implemented functions with keyword-only arguments under Python 3.1199
* In-place assignments to variables with inferred Python builtin/extension1200
types could fail with type errors if the result value type was incompatible1201
with the type of the previous value.1202
* The C code generation order of cdef classes, closures, helper code,1203
etc. was not deterministic, thus leading to high code churn.1204
* Type inference could fail to deduce C enum types.1205
* Type inference could deduce unsafe or inefficient types from integer1206
assignments within a mix of inferred Python variables and integer1207
variables.1208

Fri Jan 31 10:19:40 UTC 2014 - speilicke@suse.com1222
1223
- Update to version 0.20:1224
* Support for CPython 3.4.1225
* Support for calling C++ template functions.1226
* yield is supported in finally clauses.1227
* The C code generated for finally blocks is duplicated for each exit1228
case to allow for better optimisations by the C compiler.1229
* Cython tries to undo the Python optimisationism of assigning a bound1230
method to a local variable when it can generate better code for the1231
direct call.1232
* Constant Python float values are cached.1233
* String equality comparisons can use faster type specific code in1234
more cases than before.1235
* String/Unicode formatting using the '%' operator uses a faster1236
C-API call.1237
* bytearray has become a known type and supports coercion from and1238
to C strings. Indexing, slicing and decoding is optimised. Note that1239
this may have an impact on existing code due to type inference.1240
* Using cdef basestring stringvar and function arguments typed as1241
basestring is now meaningful and allows assigning exactly1242
str and unicode objects, but no subtypes of these types.1243
* Support for the __debug__ builtin.1244
* Assertions in Cython compiled modules are disabled if the running1245
Python interpreter was started with the "-O" option.1246
* Some types that Cython provides internally, such as functions and1247
generators, are now shared across modules if more than one Cython1248
implemented module is imported.1249
* The type inference algorithm works more fine granular by taking the1250
results of the control flow analysis into account.1251
* A new script in bin/cythonize provides a command line frontend1252
to the cythonize() compilation function (including distutils build).1253
* The new extension type decorator @cython.no_gc_clear prevents1254
objects from being cleared during cyclic garbage collection, thus1255
making sure that object attributes are kept alive until deallocation.1256
* During cyclic garbage collection, attributes of extension types that1257
cannot create reference cycles due to their type (e.g. strings) are1258
no longer considered for traversal or clearing. This can reduce the1259
processing overhead when searching for or cleaning up reference cycles.1260
* Package compilation (i.e. __init__.py files) now works, starting1261
with Python 3.3.1262
* The cython-mode.el script for Emacs was updated. Patch by Ivan Andrus.1263
* An option common_utility_include_dir was added to cythonize() to save1264
oft-used utility code once in a separate directory rather than as1265
part of each generated file.1266
* unraisable_tracebacks directive added to control printing of1267
tracebacks of unraisable exceptions.1268

1272
- update to 0.19.2:1273
* Some standard declarations were fixed or updated, including the previously1274
incorrect declaration of PyBuffer_FillInfo() and some missing bits in1275
libc.math.1276
1277
* Heap allocated subtypes of type used the wrong base type struct at the1278
C level.1279
1280
* Calling the unbound method dict.keys/value/items() in dict subtypes could1281
call the bound object method instead of the unbound supertype method.1282
1283
* "yield" wasn't supported in "return" value expressions.1284
1285
* Using the "bint" type in memory views lead to unexpected results.1286
It is now an error.1287
1288
* Assignments to global/closure variables could catch them in an illegal state1289
while deallocating the old value.1290

Mon May 13 08:17:40 UTC 2013 - dmueller@suse.com1298
1299
- update to 0.19.1:1300
* Completely empty C-API structs for extension type slots (protocols like1301
number/mapping/sequence) are no longer generated into the C code.1302
* Docstrings that directly follow a public/readonly attribute declaration1303
in a cdef class will be used as docstring of the auto-generated property.1304
This fixes ticket 206.1305
* The automatic signature documentation tries to preserve more semantics1306
of default arguments and argument types. Specifically, bint arguments1307
now appear as type bool.1308
* A warning is emitted when negative literal indices are found inside of1309
a code section that disables wraparound handling. This helps with1310
fixing invalid code that might fail in the face of future compiler1311
optimisations.1312
* Constant folding for boolean expressions (and/or) was improved.1313
* Added a build_dir option to cythonize() which allows one to place1314
the generated .c files outside the source tree.1315
