Bug #1599782: Fix segfault on bsddb.db.DB().type().
The problem is that _DB_get_type() can't be called without the GIL
because it calls a bunch of PyErr_* APIs when an error occurs.
There were no other cases in this file that it was called without the GIL.
Removing the BEGIN/END THREAD around _DB_get_type() made everything work.
Add some asserts. In sysmodule, I think these were to try to silence
some warnings from Klokwork. They verify the assumptions of the format
of svn version output.
The assert in the thread module helped debug a problem on HP-UX.
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.
with this change.]
Cause a PyObject_Malloc() failure to trigger a MemoryError, and then
add 'if (PyErr_Occurred())' checks to various places so that NULL is
returned properly.
* unified the way intobject, longobject and mystrtoul handle
values around -sys.maxint-1.
* in general, trying to entierely avoid overflows in any computation
involving signed ints or longs is extremely involved. Fixed a few
simple cases where a compiler might be too clever (but that's all
guesswork).
* more overflow checks against bad data in marshal.c.
* 2.5 specific: fixed a number of places that were still confusing int
and Py_ssize_t. Some of them could potentially have caused
"real-world" breakage.
* list.pop(x): fixing overflow issues on x was messy. I just reverted
to PyArg_ParseTuple("n"), which does the right thing. (An obscure
test was trying to give a Decimal to list.pop()... doesn't make
sense any more IMHO)
* trying to write a few tests...
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).
Fixed a few bugs on cjkcodecs:
- gbk and gb18030 codec now handle U+30FB KATAKANA MIDDLE DOT correctly.
- iso2022_jp_2 codec now encodes into G0 for KS X 1001, GB2312
codepoints to conform the standard.
- iso2022_jp_3 and iso2022_jp_2004 codec can encode JIS X 0213:2
codepoints now.
Add asserts to check for 'impossible' NULL values, with comments.
In one place where I'm not 1000% sure about the non-NULL, raise
a RuntimeError for safety.
This should fix the klocwork issues that Neal sent me. If so,
it should be applied to the release25-maint branch also.
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)
PyObject_stgdict() and PyType_stgdict() calls are non-NULL before
dereferencing the result. Hopefully this fixes what klocwork is
complaining about.
Fix a few other nits as well.
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.
