Bug #1651235: When a tuple was passed to a ctypes function call,
Python would crash instead of raising an error.
The crash was caused by a section of code that should have been
removed long ago, at that time ctypes had other ways to pass
parameters to function calls.

Verify the sizes of the basic ctypes data types against the struct
module.
Backport from trunk.

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.
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.
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).
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)
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.
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).
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.
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
- support for anonymous structure/union fields
- fix severe bug with certain arrays or structures containing more than 256 fields
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.)
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.
