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%.
