It is planned to make - 'not None' the default in a future version. For now, a warning is issued - (once per Pyrex run) if you do not specify one or the other. - - - Extension types may have a 'nogc' option to suppress GC support. - -Modifications: - - - Exceptions caught by an except clause are no longer put into the thread - state and cannot be retrieved using sys.exc_info(). To access the caught - exception, it must be bound to a name in the except clause. A third name - can be supplied to capture the traceback. - - - PyString_InternFromString is now exposed under the name 'cintern' because - it is not a complete substitute for 'intern' (it can't handle strings - containing null bytes). [John Arbash Meinel] - - - Disabled size check for cimported types because it was generating too - many false positives in the field. - - - Added __fastcall calling convention. Also no longer assuming that an - unspecified calling convention is the same as __cdecl. - - - Operations between signed and unsigned ints of the same size now have - an unsigned result. - - - Py_ssize_t now ranked between long and long long. - - - Declaration of __new__ in an extension type is now an error, in - preparation for introducing new semantics. - - - Added size_t type, and made sizeof() return it. - -Bug fixes: - - - When casting the result of a function call to a Python type, the - function could be called twice. [David Martinez] - - - __Pyx_GetException was not taking account of the fact that the traceback - could be NULL. - - - sizeof(module.typename) did not work. [Daniele Pianu] - - -0.9.8.6 -------- - -Enhancements: - - - Check for gil when calling a function declared 'execpt *' or 'except ?'. - Acquire gil when reporting unraisable exception. - - - Added iter2() function for 2-argument form of iter(). - -Bug fixes: - - - Compiler crashed if base class of extension type was incompletely - defined. - - - Compiler crash on misspelled method name in property declaration. - [Stefan Behnel] - - - Fixed deprecation warnings in 2.6 - - - Always preserve explicit type casts for non-Python types. - [Alexander Belchenko] - - - Added workaround for threading initialisation bug in Python 2.3. - [Lisandro Dalcin] - - - Deleting dict item with integer key did not work. [Titus Brown] - - - Header files for cimported modules included in wrong order. - [Stephane Drouard] - - - Don't allow a member of a ctypedef struct to reference itself. - [Tim Wakeham] - - - Compiler crash due to attribute reference in compile-time expression. - [Hoyt Koepke] - - - Public extension type attribute with cname didn't work. - [Mark Ellis] - - - Memory leak related to exporting C functions. [Lisandro Dalcin] - - - Compiler crash on return outside function. [Kurt Smith] - - - Scope problem with extension types declared in pxd. [KS Sreeram] - - - Calling a builtin method of a subclass of a builtin class did not work. - - - Builtin hash() function had wrong return type. [John Arbash Meinel] - - -Modifications: - - - Added 'tags' to .hgignore file. [Kirill Smelkov] - - - Disallow overriding a builtin method in a subclass of a builtin class. - - -0.9.8.5 -------- - -Bug fixes: - - - Function export code was erroneously generated for 'extern' functions - declared in a .pxd file. [Sebastian Sable] - - - The 'api' option was not recognised with 'ctypedef public class'. - [Lisandro Dalcin] - - - MACOSX_DEPLOYMENT_TARGET is no longer set unless the undocumented -X - option is being used. Hopefully this will prevent complaints about it - from distutils. [Martin Field] - - - Recognize MS_WINDOWS as well as WIN32. [Alexander Belchenko] - - - Hexadecimal compile-time constants did not work. [Devan] - -Enhancements: - - - Dependency files (.dep) are only created when compiling with timestamp - checking or recursion enabled. - -Deprecations: - - - The features introducted in 0.9.8 and 0.9.8.1 for cross-forward-declaring - extension types between .pxd files turn out to be unnecessary, since - the circular import problems they are aimed at can be avoided using - ordinary forward delcarations in the .pxd files ahead of any cimports. - - -0.9.8.4 -------- - -Bug fixes: - - - Incorrect code generated for Python indexing with an unsigned int. - [Christopher Williams] - - -0.9.8.3 -------- - -Bug fixes: - - - Compiling multiple source files at once should work as advertised - now. - - - Assignment of a nogil function to a non-nogil function pointer - is now allowed. - - - Applying += or -= to a pointer and an integer did not work. - [Arc Riley] - - - Compiling a .pyx file whose name is not a valid module name now - reports an error instead of generating invalid C code. - [Robert Bradshaw] - - - Integer indexing optimisation now performed only for signed - index types, to avoid change of semantics with index values - greater than the maximum positive signed int value. [Robert - Bradshaw] - - - Non-void function declared 'except *' could produce C compiler - warning about uninitialised variable. [Lisandro Dalcin] - - -0.9.8.2 -------- - -Enhancements: - - - A block of external functions can be declared nogil at once. - - cdef extern from "somewhere.h" nogil: - ... - -Bug fixes: - - - The nogil attribute was not being checked for a match when - comparing function signatures. - - - Improved error message for C method signature mismatch between - a class and its base class. - -Bug workarounds: - - - Multiple source files passed to Main.compile are being compiled - in separate contexts for the time being until I can sort out a - problem. You probably won't notice any difference except that - there will be no speed advantage over compiling them separately. - - -0.9.8.1 -------- - -Enhancements: - - - It is no longer necessary to specify the base class of an - extension type in a forward declaration. Also, if the class is - defined in a .pxd file, the base class only needs to be specified - in the .pxd file, not the .pyx file. - [Arc Riley] - - - There's now an even easier way to forward-declare a struct, union - or extension type in another module: - - from blarg cimport class Foo - - This simultaneously cimports the name Foo and forward-declares - it as an extension type. As well as 'class', you can also use - 'struct' or 'union'. - -Modifications: - - - Casting a non-Python pointer type to a Python type no longer - generates an incref, unless one is required for other reasons. - [Arc Riley] - - - More checks added for gil-requiring operations performed without - holding the gil. - - -0.9.8 ------ - -New features: - - * Augmented assignment operators (+=, etc.) are now supported. - - * Package directories - - Modules in packages no longer need to have dotted names. Instead, - a Python-like package directory structure can be used, with - package dirs marked by containing an __init__.py or __init__.pyx. - - Top-level package directories are found by searching the include - directories specified by -I options (analogous to PYTHONPATH). - - * Dependency tracking - - The Pyrex compiler records information about other source files cimported - or included, and can automatically compile all the modules a given module - depends on, with timestamp checking. - - This is enabled by a -r (recursive) option to the compiler, e.g. - - pyrexc -r mainmodule.pyx - - There are also two other new command-line options: - - -t Enable timestamp checking. This is implied with -r. - - -f Overrides implied -t when using -r and forces all - dependent modules to be compiled regardless of timestamps. - - * Nogil restrictions relaxed - - C functions declared nogil can now have Python objects as arguments. - The argument names are read-only inside the function when this is done. - - Among other things, this allows C methods to be declared nogil (this - couldn't be done before because 'self' is always an object argument). - - * Circular cimports - - There is now a way of forward-declaring a struct, union or extension type - into another module. This allows two .pxd files to define extension types - that refer to each other without running into circular import problems. - For example: - - cimport blarg - cdef class blarg.Blarg # Forward declaration - - cdef class Foo: - cdef blarg.Blarg blg - - -0.9.7.2 -------- - - Bug fixes: - - - Another integer indexing problem fixed. - - -0.9.7.1 -------- - - Bug fixes: - - - The optimisation for indexing using a C int failed when the - object being indexed was a mapping rather than a sequence. - [Arc Riley] - - Modifications: - - - Old integer for-loop syntax is no longer deprecated. - - -0.9.7 ------ - -New features: - - - Builtin constants and types are known, and are referenced directly - with no dictionary lookup. - - - Direct calls are made to certain methods of lists and dicts when - their type is statically known. - - - New builtin functions 'typecheck' and 'issubtype' added, providing - safer type checking than isinstance and issubclass (which can be - overridden). - -Enhancements: - - - Redundant type test eliminated when assigning the result of an - extension type constructor call to a variable of the same type. - - - No tp_traverse and tp_clear functions generated for types - without Python attributes. - - - Safer code generated in tp_clear. [Stefan Behnel] - - - Indexing with a C int type generates calls to PySequence_GetItem - and PySequence_SetItem. - - - Integer for-loop syntax streamlined to 'for x < i < y'. - - - Appropriate C code generated for compile-time expressions - evaluating to float nan, inf and -inf. [Stefan Behnel] - -Bug fixes: - - - Value raised by assert statement now only evaluated if the - assertion fails. [Stefan Behnel] - - - Comparing a value of an enum type with another value of a type - which is ctypedefed to the same enum type gave a spurious type - error. [Matt Hammond] - - - Comparing an int with a float resulted in the float being cast - to an int before comparison. [Robin Becker] - - - Compiler crashed on an invalid argument to a 'with nogil' statement. - [Stefan Behnel] - - - Incorrect code generated for function with keyword only args - and no * or ** args. [Stefan Behnel] - - - GC type with non-GC base type caused crash due to trying to call - non-existent base tp_traverse and tp_clear functions. [Stefan Behnel] - - - Compile-time IF with no ELSE clause crashed compiler. [Kirk McDonald] - - - Values in enum declaration were not being checked for appropriate type. - [Simon Burton] - - - Improved the error message from attempting to declare a struct or - union member as a function. [Yong Sun] - - - Referring to an undefined name in a compile-time constant crashed - the compiler. [Stefan Behnel] - - -0.9.6.4 -------- - -Bug fixes: - - - Errors in setup.py corrected. - - - Incorrect error checking code generated for builtin functions - and type slots with return type Py_ssize_t. [Robert Bradshaw] - - - A counted reference was not kept to the module, so if the entry - in sys.modules was replaced, the module was freed prematurely. - [Franck Pommerau] - - - A cimport statement inside a function crashed the compiler. - [Robert Bradshaw] - - - __Pyx_ImportModule routine wasn't protected from multiple - definition when including _api.h files. [Stefan Behnel] - - - Temp variables holding exception values were not being set to - NULL after use in an except clause. [Robert Bradshaw] - - - Protect __stdcall and __cdecl from redefinition. [Jim Kleckner] - - - A temp var was not being set to NULL after api function import - code. [Stefan Behnel] - - - __Pyx_ImportFunction was incorrectly decrefing a borrowed - reference. [Stefan Behnel] - -Enhancements: - - - Functions declared with_gil and external functions declared nogil - are now allowed to have Python arguments and return types. - - -0.9.6.3 -------- - -Enhancements: - - - C API now only uses a single name in the module namespace - instead of one for each exported C function. [Stefan Behnel] - - - Multiple declarations with the same visibility and api options - can now be grouped into a 'cdef' block. - - - The 'api' keyword can now be used on extension types to cause - generation of an api.h file when there are no exported C functions. - - - Added a getattr3() builtin for the three-argument form of getattr. - -Bug fixes: - - - Setup.py no longer uses an import to get the version number - being installed, to avoid a problem with setuptools. - - - If a struct or union was forward-declared, certain types of error - message misleadingly referenced the source location of the forward - declaration rather than the definition. - - - Calling convention specifier was being emitted in function - prototypes but not the corresponding definitions. [Atsuo Ishimoto] - - - Added support for the --force option to Pyrex.Distutils. - [Alexander Belchenko] - - - Compile-time "==" operator did not work. [Simon King] - - - Header files generated for public and api declarations now - only contain types declared as 'public', instead of all types - defined in the module. [Stefan Behnel] - - -0.9.6.2 -------- - -Bug fixes: - - - Corrected a problem with declaration ordering in generated C - code involving forward-declared struct, union or extension types. - - - New distutils extension: Only compile .pyx if it is newer - than the corresponding .c file. - - -0.9.6.1 -------- - -Bug fixes: - - - Changed os.uname to platform.uname for portability. - [Alexander Belchenko] - - - Fixed C compiler warning about incompatible types in 2.5. - [Alexander Belchenko] - - - Also fixed a few other 2.5 problems. - - - Fixed problem with the Extension class in the new Pyrex.Distutils - module. - - -0.9.6 ------ - -New Features: - - - Top-level C functions defined in one module can now be used in - another via cimport, and a C API can be produced to allow them - to be used from C code without linking to the extension module. - See "Interfacing with External C Code" and "Sharing Declarations - between Pyrex Modules" in the Language Overview. [Stefan Behnel] - - - Facilities added for releasing the GIL around a section of code - and acquiring it on entry to a C function. See "Acquiring and - Releasing the GIL under "Interfacing with External C Code" in - the Language Overview. [Ulisses Furquim, Stefan Behnel] - - - Some conditional compilation facilities have been added. See - "Conditional Compilation" under "Language Basics" in the - Language Overview. [Sam Rushing] - -Language Changes: - - - The __new__ special method of extension types is being renamed - to "__cinit__". For now, you will get a warning whenever you - declare a __new__ method for an extension type, and it will - automatically be renamed to __cinit__ for you. In the next - release, the warning will become an error and no renaming will - occur. In some later release, the __new__ method may be - re-introduced with different semantics. It is recommended that - you begin updating your sources now to use __cinit__. - - - A 'raise' statement with no arguments (i.e. to re-raise the - last exception caught) is now required to be lexically within - the 'except' clause which caught the exception. This change was - necessary to efficiently support preserving the exception if an - intervening call raises and catches a different exception. - - - The following new reserved words have been added: - - with, DEF, IF, ELIF, ELSE - -Enhancements: - - - Calls to many of the builtin functions are now compiled as - direct calls to Python/C API routines. - - - A C type explicitly declared as 'signed' is represented as - such in the generated code, to acommodate platforms where - 'char' is unsigned by default. [Francesc Altet] - - - Python function can now have an argument of type "unsigned - char". [Alexander Belchenko] - - - A new Pyrex.Distutils implementation has been added, which - exports an Extension type supporting the following options: - - pyrex_include_dirs - list of dirs to search for Pyrex header files - pyrex_create_listing_file - bool - write errs to listing file - pyrex_cplus - bool - generate C++ code - pyrex_c_in_temp - bool - put generated C files in temp dir - pyrex_gen_pxi - bool - generate .pxi file for public declarations - - [Contributed by Billie G. Allie] - - - Assert statements can be compiled out by arranging for - PYREX_WITHOUT_ASSERTIONS to be #defined at C compilation time. - [Contributed by Stefan Behnel] - - - Support for __index__ slot added to extension types. - [William Stein] - - - Exception types now properly checked according to pre or post - 2.5 rules as appropriate. - - - Py_ssize_t support added. [Stefan Behnel] - - - Windows __stdcall and __cdecl qualifiers now supported. - [Suggested by Eric Devolder] - - - Keyword-only argument support added. [Suggested by Stefan Behnel] - - - An 'include' statement can now appear anywhere that another kind - of statement or declaration can appear, instead of being restricted - to the top level. [Caio Marcelo] - - - Unnecessary PyErr_Occurred() call to check result of - PyString_AsString() no longer made. - - - Complicated C types are displayed more readably in error messages. - -Modifications: - - - A Python function argument declared as "char" or "unsigned - char" now expects a Python integer rather than a string of - length 1, for consistency with the way automatic conversions - are done elsewhere. - - - Support for string and tuple exceptions dropped. - -Bug fixes: - - - If an external ctypedef type was used as the type of an - argument to a Python function, a declaration was generated - using the underlying type rather than the typedef name. - [Francesc Altet] - - - Some problems with int/enum and pointer/array compatibility - fixed. [Eric Huss, Stefan Behnel, Jiba] - - - Eliminated C compiler warning when comparing an extension - type reference to None using 'is' or 'is not' - - - Eliminated C compiler warnings about docstrings of C functions - and special methods being unused. [Francesc Altet] - - - When compiling with -O, raising an exception in a C function - that couldn't propagate exceptions produced a compiler - warning about the return value possibly being uninitialised. - - - Fixed warning about function declaration not being a prototype - caused by C method table initialisation code. - - - Spurious initialisation was generated for unused local variable. - [Helmut Jarausch] - - - Declaration of a non-extern C function without definition - was not detected. [Lenard Lindstrom] - - - Applying ** directly to two C int types is now disallowed due - to ambiguity (it's not clear whether to use C pow() or convert - to Python ints). [Didier Deshommes] - - - Traverse and clear code was being inadvertently generated for - the __weakref__ slot of a weakly-referenceable extension type. - [Peter Johnson] - - - Statements other than def inside a property declaration were - crashing the compiler. [Sven Berkvens] - - - Defining an extension type with different visibility from its - declaration in a .pxd file crashed the compiler. - [Alex Coventry] - - - Instantiating an exception type whose base class __new__ method - raises an exception caused a segfault. [Gustavo Sverzut Barbieri] - - - The 'import pkg.module as name' form of import statement did not - work correctly. [Dan] - - - Fixed error-checking typo in __Pyx_GetStarArgs(). [Eric Huss] - - - Trailing comma now allowed on argument list. [Jim Kleckner] - - - Behaviour of reraise made to match Python more closely. - [Eric Huss] - - - An empty C variable declaration crashed the compiler. - - - Now includes math.h instead of generating own declaration - of pow(). [Leif Strand] - - - Missing import of sys in LinuxSystem.py added. [Scott Jackson] - - - Typecasts using a ctypedef type were not using the ctypedef - name. [Alexander Belchenko] - - - Workaround added to setup.py for a problem with bdist_wininst. - [Alexander Belchenko] - - - Subtle error in parsing empty function declarators corrected. - - - Checks added for some type combinations that are illegal in C: - array of functions, function returning function or array, cast - to a function. - - -0.9.5.1a --------- - -Bug fixes: - - - Package list now calculated dynamically in setup.py so that - it will work with or without the testing framework installed. - - -0.9.5.1 -------- - -Bug fixes: - - - Comparing two values of the same enum type incorrectly - produced an error. [Anders Gustafsson] - - - Compiler crash caused by assigning a Python value to - a variable of an enum type. [Peter Johnson] - - - Comparison between pointer and array incorrectly produced - a type mismatch error. [Helmut Jarausch] - - - Unused local Python variable had spurious init/cleanup code - generated for it, causing C compilation errors. [Helmut Jarausch] - - - Updated list of packages in setup.py. - -Modifications: - - - NULL in Pyrex source now translated into NULL instead of 0 - in C code, to allow for the possibility of calling something - not defined with a prototype in an external header. [Adapted Cat] - - -0.9.5 ------ - -Enhancements: - - - Exception return values may now be specified by arbitrary - constant expressions of appropriate type, not just literals. - [Stefan Behnel] - - - Redundant type check now omitted when passing a literal None - to a function expecting an extension type. [Patch by Sam Rushing] - - - New-style classes now allowed as exceptions for compatibility - with Python 2.5 (inheritance from BaseException not currently - checked). [Stefan Behnel] - - - Sequence unpacking is now done using the iterator protocol - instead of indexing. - - - Allocation of an empty tuple is avoided when making a - Python call with no arguments. [Stefan Behnel] - - - Most warnings about unused variables and labels have been - eliminated. - - - Support for running the test suite on Linux added but not - yet fully tested. [Based in part on patch by Eric Wald]. - - - Makefile included for compiling the patched Carbon File module - used by the MacOSX test code. - -Modifications: - - - Type rules for enums tightened for compatibility with C++. - - - Direct assignment from float to int disallowed to prevent - C++ compilation warnings. - - - Hex literals left as hex in C code to avoid warnings from - the C compiler about decimal constants becoming unsigned. - -Bug fixes: - - - Exception raised during argument conversion could cause crash - due to uninitialised local variables. [Konrad Hinsen] - - - Assignment to a C attribute of an extension type from a - different type could generate C code with a pointer type - mismatch. [Atsuo Ishimoto] - - - Backslash in a string literal before a non-special character - was not handled correctly. [Yuan Mang] - - - Temporary vars used by del statement not being properly - released, sometimes leading to double decrefs. [Jiba] - - - A return statement whose expression raises an exception - inside a try-except that catches the exception could cause - a crash. [Anders Gustafsson] - - - Fixed type compatibility checking problem between pointers - and arrays. [Lenard Lindstrom] - - - Circular imports between modules defining extension types - caused unresolvable import order conflicts. [Mike Wyatt] - - - Cimporting multiple submodules from the same package caused - a redefined name error for the top level name. [Martin Albrecht] - - - Incorrect reference counting when assigning to an element of an - array that is a C attribute of an extension type. [Igor Khavkine] - - - Weak-referenceable extension types were not implemented - properly. [Chris Perkins, Peter Johnson] - - - Crash if C variable declared readonly outside an extension - type definition. [Eric Huss] - -Doc updates: - - - Expanded discussion of the need for type declarations to enable - access to attributes of extension types. - - - Added a section "Source Files and Compilation" explaining the - rules for naming of source files of modules residing in packages, - and instructions for using the compiler and distutils extension. - - -0.9.4.1 -------- - -Bug fixes: - - - Fixed indentation problem in Pyrex.Distutils.build_ext. - [Oliver Grisel] - - -0.9.4 ------ - -Improvements: - - - All use of lvalue casts has been eliminated, for - compatibility with gcc4. - - - PyMODINIT_FUNC now used to declare the module init function. - - - Generated code should be compilable as either C or C++. - When compiling as C++, "extern C" is used where appropriate - to preserve linkage semantics. - - - An extension type can be made weak-referenceable by - giving it a C attribute of type object called __weakref__. - - - Source files opened in universal newlines mode. - - - Support for public extension type C attributes of type - long long and unsigned long long added (but not tested). - [Sam Rushing] - - - Distutils include directories now passed to Pyrex compiler. - [Konrad Hinsen] - - - Integer constants with an "L" suffix are now allowed - and are converted to Python long integers. [Rainer Deyke] - - - A broken .c file is no longer left behind if there are - compilation errors. - - - Using the result of a Python indexing or attribute access - operation as a char * is no longer considered an error in - most cases, as the former behaviour proved to be more - annoying than helpful. - -Bug fixes: - - - Fixed problems with conversion from Python integers to - C unsigned longs. Now use PyInt_AsUnsignedLongMask and - PyInt_AsUnsignedLongLongMask instead of the PyLong_* - functions (which only work on Python longs). [Wim Vree] - - - C unsigned ints now converted to/from Python longs intead - of Python ints to avoid overflow problems. [Heiko Wundram] - - - Correct PyArg_ParseTuple format characters now used for - unsigned types. [Jeff Bowden] - - - Nonzero return value from a base class tp_traverse call - is handled. - - - Taking sizeof an incomplete type caused a crash while - producing an error message. [Drew Perttula] - - - If a module cimported itself, definitions of global variables - were generated twice. [Parzival Herzog] - - - Distutils extension updated to handle changed signature of - swig_sources(). [David M. Cooke] - - - Incorrect C code generated for a raw string containing a double - quote preceded by a backslash. [Thomas Drake] - - - Declaration of public C function with an exception value written - to generated .pxi file without the except clause. [Robby Dermody] - - - __delitem__ method of an extension type with no __setitem__ - did not get called. [Richard Boulton] - - - A spurious Py_INCREF was generated when a return statement - required a type test. [Jonathan Doda] - - - Casting a value to a function pointer and then immediately - calling it generated a cast to a function instead of a cast - to a function pointer. [Simon Burton] - - - Py_TPFLAGS_HAVE_GC was not being set on an extension type that - inherited from an external extension type that used GC but did - not itself have any PyObject* attributes. - [Michael Hordijk] - - - A return statement inside a for statement leaked a reference - to the loop's iterator. - [Jürgen Kartnaller] - - - Full module name now appears in __module__ attribute of classes - and extension types, provided a correct dotted name is used - for the .pyx file. [Giovanni Bajo] - - - Public extension type with no C attributes produced an - invalid .pxi file. [Simon Burton] - - - Using a dict constructor as the second operand of a boolean - expression crashed the Pyrex compiler. - [Stefan Behnel] - - - A C declaration list ending with a comma resulted in invalid - C code being generated. [Alex Coventry] - - - A raw string containing two consecutive backslashes produced - incorrect C code. [Helmut Jarausch] - - - An error is reported if you attempt to declare a special - method of an extension type using 'cdef' instead of 'def'. - [Sam Rushing] - -0.9.3 ------ - -Enhancements: - - - Types defined with a ctypedef in a 'cdef extern from' block - are now referred to by the typedef name in generated C code, - so it is no longer necessary to match the type in the C - header file exactly. - - - Conversion to/from unsigned long now done with - PyLong_AsUnsignedLong and PyLong_FromUnsignedLong. [Dug Song] - - - A struct, union or enum definition in a 'cdef extern from' - block may now be left empty (using 'pass'). This can be useful - if you need to declare a variable of that type, but don't need - to refer to any of its members. - - - More flexible about ordering of qualifiers such as 'long' and - 'unsigned'. ["John (J5) Palmieri"] - - -Bug fixes: - - - Non-interned string literals used in a Python class - definition did not work. [Atsuo Ishimoto, Andreas Kostyrka] - - - Return types of the buffer interface functions for extension - types have been corrected. [Dug Song] - - - Added 'static' to declarations of string literals. [Phil Frost] - - - Float literals are now copied directly to the C code as written, - to avoid problems with loss of precision. [Mario Pernici] - - - Inheriting from an extension type with C methods defined in - another Pyrex module did not work. [Itamar Shtull-Trauring] - -0.9.2.1 -------- - -Bug fixes: - - - Corrected an import statement setup.py, and made it - check for a unix platform in a more reliable way. - -0.9.2 ------ - -Enhancements: - - - Names of Python global variables and attributes are now - interned, and PyObject_GetAttr/SetAttr are used instead - of PyObject_GetAttrString/SetAttrString. String literals - which resemble Python identifiers are also interned. - - - String literals are now converted to Python objects only - once instead of every time they are used. - - - NUL characters are now allowed in Python string literals. - - - Added some missing error checking code to the beginning - of module init functions. It's unlikely the operations - involved would ever fail, but you never know. - -Bug fixes: - - - Corrected some problems introduced by moving the Plex - package. - -0.9.1.1 -------- - -Bug fixes: - - - Corrected a problem in the setup.py (pyrexc script incorrectly - named). - - - Updated the distutils extension to match changes in the - Pyrex compiler calling interface. - - - Doing 'make clean' in Demos/callback was removing a little too - much (that's why cheesefinder.c kept disappearing). - -0.9.1 ------ - -Enhancements: - - - A C method can now call an inherited C method by the usual - Python technique. [Jiba] - - - The __modname__ of a Python class is now set correctly. [Paul Prescod] - - - A MANIFEST.in file has been added to the distribution to - facilitate building rpms. [contributed by Konrad Hinsen] - -Bug fixes: - - - Conditional code now generated to allow for the renaming of LONG_LONG - to PY_LONG_LONG that occurred between Python 2.2 and 2.3. - - - Header files referenced in cimported modules were not being included. - [Tom Popovich] - - - References to C functions and variables in a cimported module were - not being recognised if made from within a local scope. [Tom Popovich] - - - Spurious declarations in code generated for a "finally" block. - [Brandon Long] - - - Attempting to return a value from a __contains__ method didn't work. - [Andreas Kostyrka] - - - Incorrect code generated for an extension type with C methods - inheriting from a base type with no C methods. [Robin Becker] - - - Failure to report an error if a C method was defined in the - implementation part of an extension type that was not declared - in the corresponding definition part. Documentation also updated - to explain that this is necessary. [Jiba] - - - Made it an error to forward-declare an extension type with - a different base class specification from its subsequent - definition. [Jiba] - - - C attributes of an extension type were not being propagated - through more than one level of inheritance. [Jiba] - - - If a garbage collection occurred early enough in the __new__ - method of an extension type with Python-valued C attributes, - a crash could occur in its tp_traverse function. - [reported by Jiba, fix suggested by Paul Prescod] - - - An empty vtable struct is no longer generated for extension - types with no C methods. [Robin Becker] - - - Memory was leaked in the sq_item function of an extension - type with a __getitem__ method. [Atsuo Ishimoto] - - - Code generated to work around a bug in some versions of Python - 2.2 which fails to initialise the tp_free slot correctly in - some circumstances. [Matthias Baas] - - - Compiler crash when defining an extension type with a base - class specified by a dotted name. [Alain Pointdexter] - - - Referencing an extension type defined in a cimported module - at run time did not work correctly. [Alain Pointdexter] - - - Incorrect object struct code generated for an extension type - whose base class was defined in a .pxd file. [Alain Pointdexter] - - - Redeclaring a type that wasn't previously an extension type - as an extension type caused a compiler crash. [Scott Robinson] - - - Incorrect code was generated for return statements in a - special method with no return value. [Gary Bishop] - - - Single-line def statement did not work. [Francois Pinard] - -Modifications: - - - Only the last pathname component of the .pyx file is reported in - backtraces now. [Bryan Weingarten] - - - Documentation corrected to remove the erroneous statement that - extension classes can have a __del__ method. [Bryan Weingarten] - - - Note added to documentation explaining that it is not possible - for an extension type's __new__ method to explicitly call the - inherited __new__ method. - - - The version of Plex included with Pyrex is now installed - as a subpackage of the Pyrex package, rather than as a - top-level package, so as not to interfere with any other - version of Plex the user may have installed. - -0.9 ---- - -New features: - - - Extension types can have properties. See the new "Properties" - section in the "Extension Types" page. - - - An extension type can inherit from a builtin type or another - extension type. See "Subclassing" in the "Extension Types" page. - - - Extension types can have C methods, which can be overridden - in derived extension types. See "C Methods" in the "Extension Types" - page. - -Enhancements: - - - Conversion is now performed between C long longs and Python - long integers without chopping to the size of a C long. - Also the Python PY_LONG_LONG type is now used for long longs - for greater portability. - -Bug fixes: - - - Names were sometimes being generated that were insufficiently - unique in the presence of cimported declarations. - - - Changed the way the included filename table is declared from - char *[] to char **, to stop MSVC from complaining about it - having an unknown size. [Alexander A Naanou] - - - Second argument of assert statement was not being coerced - to a Python value. [Francois Pinard] - - - Return statement without value wasn't accepted in some - extension type special methods when it should have been. - [Francois Pinard] - - - Attempting to call a non-function C value crashed the - compiler. [John J Lee] - - - Functions declared as "except *" were not returning exceptions. - [John J Lee] - - - A syntax warning from Plex about assignment to None has - been eliminated. [Gordon Williams] - - - Public function declaration with empty argument list was - producing (void) in .pxi file. [Michael P. Dubner] - - - Incorrect error signalling code was being generated in the - __hash__ special method of an extension type. - - -0.8.1 ------ - -Bug fixes: - - - Names of structs, unions and enums in external header - files were getting mangled when they shouldn't have been. - [Norman Shelley] - - - Modified distutils extension so that it will stop before - compiling the C file if the Pyrex compiler reports errors. - [John J Lee] - - -0.8 ---- - -New features: - - - INCOMPATIBLE CHANGE: The type object of an external extension - type is now imported at run time using the Python import - mechanism. To make this possible, an 'extern' extension type - declaration must DECLARE THE MODULE from which the extension - type originates. See the new version of the "Extension Types" - documentation for details. - - This change was made to eliminate the need for Pyrex to be - told the C name of the type object, or for the Pyrex module - to be linked against the object code providing the type object. - - You will have to update any existing external extension type - declarations that you are using. I'm sorry about that, but it - was too hard to support both the old and new ways. - - - Compile-time importing: A Pyrex module can now import declarations - from another Pyrex module using the new 'cimport' statement. See - the new section on "Sharing Declarations Between Pyrex Modules" in - the documentation. - -Minor improvements: - - - An error is reported if you declare a struct, union or - extension type using 'cdef' in one place and 'ctypedef' - in another. - - - Struct, union and extension types can only be forward- - declared using 'cdef', not 'ctypedef' (otherwise invalid - C code would be generated). - - - The 'global' statement can be used at the module level to - declare that a name is a module-level name rather than a - builtin. This can be used to access module attributes such - as __name__ that would otherwise be assumed to be builtins. - [Pat Maupin] - - - The 'assert' statement now accepts a second argument. - [Francois Pinard] - -Bug fixes: - - - When using Python 2.3, "True" or "False" could sometimes - turn up in generated code instead of "1" or "0". [Adam Hixson] - - - Function return value not always converted to or from a - Python object when it should have been. - - - Certain kinds of error in a function call expression - could crash the compiler. ["Edward C. Jones"] - - - Fixed memory leak in functions with * or ** args. [Alexander A Naanou] - - -0.7.1 ------ - -Bug fixes: - - - Calling a function declared as returning an extension - type could crash the compiler. - - - A function call with type errors in the argument list - could crash the compiler. - - - An 'else' clause on a for-from statement could crash - the compiler. - - - Incorrect casting code was generated when a generic - object argument of a special method was declared as - being of an extension type. [Phillip J. Eby] - - - A blank line that couldn't be interpreted wholly as - a valid indentation sequence caused a syntax error. - In particular, a formfeed character on an otherwise - blank line wasn't accepted. [Francois Pinard] - - - Parallel assignments were incorrectly optimised. - - - A bare tuple constructor with an extra comma at the - end of a line caused a syntax error. - -0.7 ---- - -New features: - - - Attributes of extension types can be exposed to Python - code, either read/write or read-only. - - - Different internal and external names can be specified - for C entities. - - - None is a compile-time constant, and more efficient code - is generated to reference it. - - - Command line options for specifying directories to - search for include files. - -Enhancements: - - - More efficient code is generated for access to Python - valued C attributes of extension types. - - - Cosmetic code improvement: Less casting back and forth - between extension types and PyObject * when referencing - C members of the object struct. - - - C arguments and variables declared as an extension type - can take the value None. - - - Form feed characters are accepted as whitespace. - - - Function names in tracebacks are qualified with - module name and class name. - -Bug fixes: - - - A sufficiently complex expression in a boolean context - could cause code to be generated twice for the same - subexpression. - - - Incorrect casting code was generated when passing an - extension type to a function expecting a generic Python - object. - - - Executable statements are now disallowed inside a - cdef class block (previously they silently caused - crazy C code to be generated). - - - Tracebacks should now report the correct filename for - functions defined in files included with the 'include' - statement. - - - The documentation incorrectly claimed that an extension - type can't have a __del__ method. In fact, it can, and - it behaves as expected. - - -0.6.1 ------ - -Bug fixes: - - - Fixed broken distutils extension. - - - -0.6 ---- - -New features: - - - Command line options for reporting version number, - requesting a listing file and specifying the name of - the generated C file. - - - An 'include' statement allows inclusion of declarations - from other Pyrex source files. - - - If there are any public declarations, a Pyrex include - file is generated (as well as a .h file) containing - declarations for them. - - - Extension types can be declared public, so their C - attributes are visible to other Pyrex and C code. - - - Try-except statements can now have an 'else' clause. - [Francois Pinard] - - - Multiple simple statements can be placed on one line - separated by semicolons. - - - A suite consisting of a simple statement list can now - be placed on the same line after the colon in most - cases. [Francois Pinard] - - - The automatic coercion of a C string to a C char has - been removed (it proved to be too error-prone). - Instead, there is a new form of literal for C - character constants: c'X' - - - The __get__ special method (used by descriptor objects) - now allows for the possibility of the 2nd or 3rd - arguments being NULL. Also the __set__ method has been - split into two methods, __set__ and __delete__. - [Phillip J. Eby] - -Bug fixes: - - - Values unpacked into a non-Python destination variable - were not being converted before assignment. [Gareth Watts] - - - Hex constants greater than 0x7fffffff caused compiler - to crash. [Gareth Watts] - - - Type slots are no longer statically initialised with - extern function pointers, to avoid problems with - some compilers. The hack in the distutils extension - to work around this by compiling as C++ has been - disabled. [Phillip J. Eby] - - - Fixed several more instances of the error-reporting - routine being called with arguments in the wrong - order. Hoping I've *finally* got all of them now... - - - Nested for-from loops used the same control variable. - [Sebastien de Menten] - - - Fixed some other error message related bugs. [Francois Pinard] - - - Assigning to slice didn't work. [Francois Pinard] - - - Temp variables were being declared as extension - types and then being assigned PyObject *'s. All - Python temp vars are now declared as PyObject *. - [Francois Pinard] - -0.5 ---- - -Bug fixes: - - - Algorithm for allocating temp variables redesigned - to fix various errors concerning temp - variable re-use. [Mark Rowe] - - - Memory leak occured sometimes when an implicit - type test was applied to the result of an - expression. [Christoph Wiedemann] - - - __set__ method of extension types had wrong - signature. [Josh Littlefield] - -0.4.6 ------ - -Bug fixes: - - - Indexing multi-dimensional C arrays didn't - work. [Gary Dietachmayer] - - -0.4.5 ------ - -New features: - - - There is now a 'public' declaration for - making Pyrex-defined variables and functions - available to external C code. A .h file is - also generated if there are any public - declarations. - -Enhancements: - - - Defining __len__/__getitem__ methods in an - extension class fills sq_length/sq_item slots - as well as mp_length/mp_subscript. [Matthias Baas] - - - The Distutils extension now allows .c files - to be incorporated along with .pyx files. - [Modification to Distutils extension contributed - by Darrell Gallion] - -Bug fixes: - - - Float literals without a decimal point - work again now. [Mike Rovner, Peter Lepage] - - - Compiler crashed if exception value didn't - match function return type. [Michael JasonSmith] - - - The setup.py file should now install the - Lexicon.pickle file in the right place. - [Patch supplied by David M. Cooke] - - - Compiler crashed when compiling a C function that - returned an extension type. - [David M. Cooke] - - - Anonymous enum types did not have C code - suppressed inside an extern-from block. [Matthew Mueller] - - -0.4.4 ------ - -Enhancements: - - - Tracebacks now extend into Pyrex function - calls and show line numbers in the Pyrex - source file. - - - Syntax for float literals made more lenient - (no longer requires digits both before and - after the point). [Peter Lepage] - - - Method calls can be made on string literals - (e.g. ",".join(x)). [Pedro Rodriguez] - -Bug fixes: - - - Incorrect refcount code generated when a - Python function needing argument type tests - had local Python variables. [Matthias Baas] - - - 'self' parameter of __getitem__ method of - extension type had wrong implicit type. [Peter Lepage] - - - Repaired breakage introduced by trying to - allow an empty parameter list to be written - as (void). No longer attempting to allow - this (too hard to parse correctly). [Peter Lepage] - - - Found bug in Plex 1.1.2 which was the *real* - cause of the two-newlines-in-a-row problem. - Removed the Opt(Eol)+Str("\n") hacks in - the scanner which were working around this - before. [Pedro Rodriguez] - - - __call__ special method of extension types - had wrong signature. [Peter Lepage] - - -0.4.3 ------ - -New language features: - - - For-from loop for iterating over integer - ranges, using pure C loop where possible. - -Enhancements: - - - sizeof() can now be applied to types as - well as variables. - - - Improved handling of forward-declared - extension types. - -Bug fixes: - - - Two newlines in a row in a triple quoted - string caused a parse error on some - platforms. [Matthias Baas] - - - Fixed problem with break and continue in - the else-clause of a loop. - - -0.4.2 ------ - -New language features: - - - C functions can be declared as having an - exception return value, which is checked - whenever the function is called. If an - exception is detected inside a C function - for which no exception value is declared, - a warning message is printed and the - exception is cleared. - - - Cascaded assignments (i.e. a = b = c - are now supported. - - - Anonymous enum declarations are allowed, - for when you just want to declare constants. - - - The C types "long long" and "long double" - are now understood. Also, "int" is optional - after "short" or "long". - -Enhancements: - - - A * argument in a function call can now be - any sequence, not just a tuple. - - - A C char* or char[] will be turned into - a char by taking its first character if - used in a context where a char is required, - thus allowing a string literal to be used as - a char literal. - - - C string * C int or vice versa is now - interpreted as Python string replication. - - - Function arguments are checked for void or - incomplete type. - -Bug fixes: - - - Non-external extension types show up in the - module dict once more (this got broken in - 0.4.1). - - - A spurious decref has been removed from the - runtime support code for the "import" statement. - Hopefully this will prevent the crashes some - people have been experiencing when importing - builtin modules. [Mathew Yeates] - -0.4.1 ------ - -New language features: - - - "ctypedef struct/union/enum/class" statements - added, for use in extern-from blocks when a - header file uses a ctypedef to declare a - tagless struct, union or enum type. - - - "pass" allowed in an extern-from block. - - - "cdef extern from *" for when you don't want - to specify an include file name. - - - Argument names may be omitted in function - signatures when they're not needed. - - - New reserved word NULL for the null C pointer. - -Compiler enhancements: - - - Lexicon is now picked in binary format, so - startup should be much faster on slower - machines. - - - If Pyrex decides to rebuild the lexicon and - then finds that it can't write a pickle file, - it now prints a warning and carries on - instead of crashing. - - - Chat about hash codes and lexicon pickling - now turned off by default except when creating - a new lexicon (which ought never happen now - unless you change the scanner). - -Bug fixes: - - - Modified the runtime support code for "import" - statements, hopefully fixing problem with using - a Pyrex module in conjunction with py2exe. - - - DL_EXPORT now used in both the prototype and - definition of the module init function. - - - Exception state is now saved and restored around - calls to an extension type __dealloc__ method, - to avoid screwing up if the object is deallocated - while an exception is being propagated. - - - Making an attribute reference to a method of - an extension type caused a compiler crash. - - - Doc string in new-style class definition - caused a run-time error. - - - Insufficient parentheses were put around C type - casts. - - - Constructors for extension types are now read-only - C global variables instead of entries in the - module dict. This change was needed to prevent - Numeric from blowing up due to touching its - typeobject before import_numeric() could be called. - -0.4 ---- - -New features: - - - "cdef extern from" statement allows inclusion - of C header files to be specified, solving - a number of problems including: - - Clashes between Pyrex and C declarations, - due to "const" and other reasons - - Windows-specific features required in - function declarations - - Helping deal with types such as "size_t" - - Helping deal with functions defined as - macros - - - Access to internals of pre-existing extension - types is now possible by placing an extension - type declaration inside a "cdef extern from" - block. - -Bug fixes: - - - Error not reported properly when passing - wrong number of args to certain special - methods of extension types. [Mitch Chapman] - - - Compile-time crash when defining an extension - type with a __hash__ method. - -Minor enhancements: - - - Hashing of the scanner source file made more - platform-independent, making spurious regeneration - of the pickle less likely. - - -0.3.4 ------ - -Bug fixes: - - - Runtime crash when using * or ** args in - a method of an extension type fixed. [Matthew Mueller] - - - Compiler crash when using default argument - values in a method of a Python class. [Mike Rovner] - -Enhancements: - - - Type slots filled with functions from outside - the extension module are now initialised dynamically, - which should eliminate at least some of the - "initialiser is not constant" problems experienced - on Windows. [Marek Baczek] - - - On Windows, __declspec(dllexport) is now used for - the module init func declaration (or should be -- - I haven't tested this). [Marek Baczek] - - - The compiler shouldn't attempt to rewrite the - Lexicon.pickle file unless the source has been - changed (hashing is used now instead of comparing - timestamps). So there should be no problem any more - with installing Pyrex read-only. - -0.3.3 ------ - -Bug fixes: - -* A void * can be assigned from any other -pointer type. -* File names in error messages no longer -quoted (this was apparently confusing some -editors). [Matthew Mueller] - -* Reference to a struct member which is an -array is coerced to a pointer. [Matthew Mueller] - -* Default argument values did not work -in methods of an extension type. [Matthew Mueller] - -* Single or double quote characters in a -triple-quoted string didn't work. [Matthew Mueller] - -* Using *args in a function definition -sometimes caused a crash at runtime. [Matthew Mueller] - -* A hack is included which tries to make -functions in Python.h which use 'const' -accessible from Pyrex. But it doesn't -work on all platforms. Thinking about a -better solution. - - -New features: - -* Comment containing Pyrex version number -and date/time at top of generated C file. [Matthias Baas] - - -0.3.2 ------ - -Bug fixes: - -* The & operator works again. [Matthias Baas] - -* The & operator had incorrect precedence. - -* "SystemError: 'finally' pops bad exception" -under some circumstances when raising an -exception. [Matthias Baas] - -* Calling a Python function sometimes leaked -a reference. - -* Crash under some circumstances when casting -a Python object reference to a C pointer type. -[Michael JasonSmith] - -* Crash when redeclaring a function. [Matthias Baas] - -* Crash when using a string constant inside -a Python class definition. [Mike Rovner] - -* 2-element slice indexing expressions. [Mike Rovner] - -* Crash when encountering mixed tabs and -spaces. [Mike Rovner] - -New features: - -* A wider variety of constant expressions is -now accepted for enum values, array -dimensions, etc. [Mike Rovner] - - -0.3.1 ------ - -New features: - -* More special methods for extension types: -__delitem__, __delslice__, __getattr__, -__setattr__, __delattr__ - -* Module-level variable of a Python object type -declared with 'cdef' is private to the module, and -held in a C variable instead of the module dict. - -* External C functions with variable argument lists -can be declared and called. - -* Pyrex-defined Python functions can have default -argument values and * and ** arguments, and can be -called with keyword arguments. - -* Pointer-to-function types can be declared. - -* Pyrex now supports a declaration syntax that -C doesn't! Example: - - cdef (int (*)()) foo() # function returning a function ptr - -* There is now a ctypedef statement. - -* Extension types can now be forward-declared. - -* All permutations of (non-Unicode) string literals -and escape codes should work now. - -* Hex and octal integer literals. - -* Imaginary number literals. - -* Docstrings are now supported. - -Bug fixes: - -* Type tests are performed when using a Python object -in a context requiring a particular extension type. - -* Module-level variable holding the type object -of an extension type had incorrect type. - -0.3 ---- - -New features: - -* Extension types! Yay! - -0.2.2 ------ - -Bug fixes: - -* Fixed error message generation again after a previous -bug was accidentally re-indroduced. - -* Removed the declaration of isspace() from the code -generated for print statement support (it's not needed -and was conflicting with the system-supplied one on -some platforms). - -0.2 ---- - -New features: - -* Executable statements are now allowed at the -top level of a module. - -* Python class definitions are now supported, with -the following limitations: - - - Class definitions are only allowed at the top - level of a module, not inside a control structure - or function or another class definition. - - - Assigning a Pyrex-defined Python function to a - class attribute outside of the class definition - will not create a method (because it's not an - interpreted Python function and therefore - won't trigger the bound-method creation magic). - - - The __metaclass__ mechanism and the creation of - new-style classes is not (yet) supported. - -* Casting between Python and non-Python types is -better supported. - -Bug fixes: - -* Fixed bug preventing for-loops from working. - - -0.1.1 ------ - -* I've discovered a flaw in my algorithm for releasing -temp variables. Fixing this properly will require some -extensive reworking; I've put in a hack in the meantime -which should work at the cost of using more temp variables -than are strictly necessary. - -* Fixed bug preventing access to builtin names from -working. This should also have fixed the import -statement, but I haven't tested it. - -* Fixed some errors in __Pyx_GetExcValue. - -* Fixed bug causing boolean expressions to malfunction -sometimes. |
