Thomas Heller a06a1a88ee Add pickle support to ctypes types. 2008-02-13 20:21:53 +00:00
Brett Cannon 8352585909 Make sure a switch statement does not have repetitive case statements.
Error found through LLVM post-2.1 svn.
2008-02-07 22:27:10 +00:00
Thomas Heller 55b8c3e26f Fixed refcounts and error handling.
Should not be merged to py3k branch.
2008-02-06 20:29:17 +00:00
Thomas Heller 99120c4f7e Revert rev. 59925, it breaks comtypes (I need to further examine this). 2008-01-28 08:44:13 +00:00
Christian Heimes d7e1b2bd17 static PyObject* variables should use PyString_InternFromString() instead of PyObject_FromString() to store a python string in a function level static var. 2008-01-28 02:07:53 +00:00
Neal Norwitz b3c8243c47 Update to newer version of ffi. Fixes crashes and test failures of longdouble 2008-01-27 17:10:43 +00:00
Thomas Heller 5ca924038d Invert the checks in get_[u]long and get_[u]longlong. The intent was
to not accept float types; the result was that integer-like objects
were not accepted.

Ported from release25-maint.

Thomas Heller 71dba4ccee Replace Py_BuildValue with PyTuple_Pack because it is faster.
Also add a missing DECREF.
2008-01-24 18:54:12 +00:00
Thomas Heller e4c03e4520 Use a PyDictObject again for the array type cache; retrieving items
from the WeakValueDictionary was slower by nearly a factor of 3.

To avoid leaks, weakref proxies for the array types are put into the
cache dict, with weakref callbacks that removes the entries when the
type goes away.

Brett Cannon a35a8b11c3 Fix a function pointer declaration to silence the compiler. 2008-01-17 18:45:10 +00:00
Thomas Heller 0f75f9847a Use 'g' instead of 'D' as the ctypes typecode for c_longdouble, for
compliance with PEP 3118.
2008-01-16 20:34:37 +00:00
Thomas Heller 415c1e36a9 Raise a TypeError instead of a ValueError when too many initializers
are used in a Structure or Union constructor.
2008-01-16 19:45:51 +00:00
Thomas Heller 02ec289f3e Raise a TypeError if conflicting positional and named arguments are
passed to a Structure or Union constructor.
2008-01-16 19:37:33 +00:00
Thomas Heller 902d30752f Convert the internal ctypes array type cache to a WeakValueDict so
that array types do not live longer than needed.

Thomas Heller 7a66a1becc Issue 1821: configure libffi for amd64 on FreeeBSD. 2008-01-14 10:35:28 +00:00
Amaury Forgeot d'Arc 7cdf5f5c31 ?Why did my tests not notice this before?
Slots inheritance is very different from OO inheritance.
This code lead to infinite recursion on classes derived from StructType.
2008-01-14 01:07:27 +00:00
Amaury Forgeot d'Arc 08ccf202e6 As discussed in issue 1700288:
ctypes takes some liberties when creating python types: it modifies the types'
__dict__ directly, bypassing all the machinery of type objects which deal with
special methods.  And this broke recent optimisations of method lookup.
Now we try to modify the type with more "official" functions.
2008-01-14 00:22:44 +00:00
Thomas Heller 43617bc610 Fix a potential 'SystemError: NULL result without error'.
NULL may be a valid return value from PyLong_AsVoidPtr.

Will backport to release25-maint.
2008-01-11 20:29:19 +00:00
Thomas Heller c682614df0 Raise an error instead of crashing with a segfault when a NULL
function pointer is called.

Will backport to release25-maint.

Thomas Heller 41f278ffa5 Use relative instead of absolute filenames in the C-level tracebacks.
This prevents traceback prints pointing to files in this way:

  File "\loewis\25\python\Modules\_ctypes\callbacks.c", line 206, in 'calling callback function'
2008-01-08 15:15:09 +00:00
Christian Heimes 000a074c95 Modified PyImport_Import and PyImport_ImportModule to always use absolute imports by calling __import__ with an explicit level of 0
Added a new API function PyImport_ImportModuleNoBlock. It solves the problem with dead locks when mixing threads and imports

Christian Heimes e93237dfcc #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE and Py_REFCNT. Macros for b/w compatibility are available. 2007-12-19 02:37:44 +00:00

implementation in C.
2007-11-27 12:22:11 +00:00
Thomas Heller 469b2a52cd ffi_type_longdouble may be already #defined.
See issue 1324.

Thomas Heller 2825b2ea44 Add a 'c_longdouble' type to the ctypes module. 2007-09-07 06:32:17 +00:00
Matthias Klose 38336406eb - Fix libffi configure for hppa*-*-linux* | parisc*-*-linux*. 2007-09-04 20:46:02 +00:00
Thomas Wouters dcb3c382ac Somewhat-preliminary slice-object and extended slicing support for ctypes.
The exact behaviour of omitted and negative indices for the Pointer type may
need a closer look (especially as it's subtly different from simple slices)
but there's time yet before 2.6, and not enough before 3.0a1 :-)

Martin v. Löwis 6819210b9e PEP 3123: Provide forward compatibility with Python 3.0, while keeping
backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
PyVarObject_HEAD_INIT.

Thomas Heller fe31d77dc0 PyType_stgdict() returns a borrowed reference which must not be
Py_DECREF'd.

Thomas Heller ef4fff3435 Fix for SF# 1649098: avoid zero-sized array declaration in structure. 2007-07-13 17:46:54 +00:00
Thomas Heller 1421b00162 Repair COMError. Since exceptions are new style classes now, setting
the methods and docstring after the type creation does not work, they
must be in the dictionary before creating the type.
2007-07-13 13:59:39 +00:00
Thomas Heller 410c3b58c9 Use "O&" in calls to PyArg_Parse when we need a 'void*' instead of "k"
or "K" codes.

Thomas Heller 1ad576c267 Do not truncate 64-bit pointers to 32-bit integers.
Fixes SF #1703286, will backport to release25-maint.
2007-05-04 19:54:22 +00:00
Thomas Heller db3bfdf141 On 64-bit Windows, ffi_arg must be 8 bytes long. This fixes the
remaining crashes in the ctypes tests, when functions return float or
double types.
2007-05-04 08:20:41 +00:00
Thomas Heller 9b73d0aed5 Don't truncate pointers to integers (on win64 platform). 2007-05-03 12:05:20 +00:00
Thomas Heller 68bb9a1418 When accessing the .value attribute of a c_wchar_p instance, and the
instance does not point to a valid wchar_t zero-terminated string,
raise a ValueError.  c_char_p does this already.

The ValueError message now contains the correct pointer address.

Will backport to release25-maint.
2007-04-30 16:04:57 +00:00
Thomas Heller 5a901bd3cc Make sure to call PyErr_NoMemory() in several places where
PyMem_Malloc() could potentially fail.

Will backport to the release25-maint branch.

Thomas Heller e6a7039451 Prevent creation (followed by a segfault) of array types when the size
overflows the valid Py_ssize_t range.  Check return values of
PyMem_Malloc.

Will backport to release25-maint.
2007-03-23 19:55:27 +00:00
Thomas Heller 82730f8d11 Explain the purpose of the b_needsfree flag (forward ported from release25-maint). 2007-03-22 20:34:37 +00:00
Thomas Heller f493cbd824 Back out "Patch #1643874: memory leak in ctypes fixed."
The code in this patch leaves no way to give up the ownership of a
BSTR instance.
