Thomas Heller dcbf64d34d ctypes callback functions only support 'fundamental' result types.
Check this and raise an error when something else is used - before
this change ctypes would hang or crash when such a callback was
called.  This is a partial fix for #1574584.

Backported from trunk.

Neal Norwitz 5728c27c74 Backport rev 51820 from Thomas Heller
The cast function did not accept c_char_p or c_wchar_p instances
as first argument, and failed with a 'bad argument to internal function'
error message.

Neal Norwitz 71e2aa0cc5 Backport rev 51819 from Thomas Heller
Anonymous structure fields that have a bit-width specified did not work,
and they gave a strange error message from PyArg_ParseTuple:
   function takes exactly 2 arguments (3 given).

Thomas Heller b4a0cf17c4 Remove the special casing of Py_None when converting the return value
of the Python part of a callback function to C.  If it cannot be
converted, call PyErr_WriteUnraisable with the exception we got.
Before, arbitrary data has been passed to the calling C code in this
case.

(I'm not really sure the NEWS entry is understandable, but I cannot
find better words)

Thomas Heller b0aa98fd4f The __repr__ method of a NULL py_object does no longer raise an
exception.  Remove a stray '?' character from the exception text
when the value is retrieved of such an object.

Includes tests.

Thomas Heller 867200483b Apply the patch #1532975 plus ideas from the patch #1533481.
ctypes instances no longer have the internal and undocumented
'_as_parameter_' attribute which was used to adapt them to foreign
function calls; this mechanism is replaced by a function pointer in
the type's stgdict.

In the 'from_param' class methods, try the _as_parameter_ attribute if
other conversions are not possible.

This makes the documented _as_parameter_ mechanism work as intended.

Change the ctypes version number to 1.0.1.

Thomas Heller 09a6f6aad2 Remove code that is no longer used (ctypes.com).
Fix the DllGetClassObject and DllCanUnloadNow so that they forward the
call to the comtypes.server.inprocserver module.

The latter was never documented, never used by published code, and
didn't work anyway, so I think it does not deserve a NEWS entry (but I
might be wrong).

Thomas Heller ce049a0aef Patch #1521817: The index range checking on ctypes arrays containing
exactly one element is enabled again.

Thomas Heller 2bdf29ec28 Fix #1521375. When running with root priviledges, 'gcc -o /dev/null'
did overwrite /dev/null.  Use a temporary file instead of /dev/null.

Thomas Heller 47d7a069d1 Fix #1467450: ctypes now uses RTLD_GLOBAL by default on OSX 10.3 to

ctypes.c_void_p constructor.
2006-07-10 09:10:28 +00:00
Thomas Heller 5becdbee96 Patch #1517790: It is now possible to use custom objects in the ctypes
foreign function argtypes sequence as long as they provide a
from_param method, no longer is it required that the object is a
ctypes type.

Thomas Heller 2329b64c20 The test that calls a function with invalid arguments and catches the

Thomas Heller 43d9a58dfd Revert the change done in svn revision 47206:
Add a new function uses_seh() to the _ctypes extension module.  This
will return True if Windows Structured Exception handling (SEH) is
used when calling functions, False otherwise.
2006-07-06 07:50:18 +00:00
Thomas Heller f780be4239 Add a new function uses_seh() to the _ctypes extension module. This
will return True if Windows Structured Exception handling (SEH) is
used when calling functions, False otherwise.

Currently, only MSVC supports SEH.

Fix the test so that it doesn't crash when run with MingW compiled
_ctypes.  Note that two tests are still failing when mingw is used, I
suspect structure layout differences and function calling conventions
between MSVC and MingW.

Summary of changes:

- support for 'variable sized' data

Thomas Heller 56dab85022 Specify argtypes for all test functions. Maybe that helps on strange ;-) architectures 2006-06-06 15:34:18 +00:00
Martin Blais 215f13dd11 Normalized a few cases of whitespace in function declarations.
Found them using::

  find . -name '*.py' | while read i ; do grep 'def[^(]*( ' $i /dev/null ; done
  find . -name '*.py' | while read i ; do grep ' ):' $i /dev/null ; done

(I was doing this all over my own code anyway, because I'd been using spaces in
all defs, so I thought I'd make a run on the Python code as well.  If you need
to do such fixes in your own code, you can use xx-rename or parenregu.el within
emacs.)

Thomas Heller ecc3e67b98 Convert CFieldObject tp_members to tp_getset, since there is no
structmember typecode for Py_ssize_t fields.  This should fix some of
the errors on the PPC64 debian machine (64-bit, big endian).

Assigning to readonly fields now raises AttributeError instead of
TypeError, so the testcase has to be changed as well.

Tim Peters 319c47fcdb Try to repair what may be the last new test failure on the
"x86 OpenBSD trunk" buildbot due to changing Python so that
Python-exposed addresses are always non-negative.

test_int_pointer_arg():  This line failed now whenever the
box happened to assign an address to `ci` "with the sign
bit set":

    self.failUnlessEqual(addressof(ci), func(byref(ci)))

The problem is that the ctypes addressof() inherited "all
addresses are non-negative now" from changes to
PyLong_FromVoidPtr(), but byref() did not inherit that
change and can still return a negative int.

I don't know whether, or what, the ctypes implementation wants
to do about that (possibly nothing), but in the meantime
the test fails frequently.

So, introduced a Python positive_address() function in
the test module, that takes a purported machine address and,
if negative, converts it to a non-negative value "with the
same bits".  This should leave the test passing under all
versions of Python.

Belated thanks to Armin Rigo for teaching me the sick trick ;-)
for determining the # of bits in a machine pointer via abuse
of the struct module.

Thomas Heller fff61ea025 Expose RTLD_LOCAL and RTLD_GLOBAL always from the _ctypes extension module.
If RTLD_LOCAL is not #defined in any header file (Windows), set it to 0.
If RTLD_GLOBAL is not #defined, set it equal to RTLD_LOCAL.

This should fix ctypes on cygwin.
