statement recompilation with no bound parameters lead to a segfault
- Backported a fix necessary because of an SQLite API change in version 3.5.
This prevents segfaults when executing empty queries, like our test suite
does.
Undoes incorrect dbtables fix and errant strdup introduced as
described below:

Fix bug introduced in revision 58385. Database keys could no longer
have NULL bytes in them. Replace the errant strdup with a
malloc+memcpy. Adds a unit test for the correct behavior.

Undo revision 58533 58534 fixes. Those were a workaround for
a problem introduced by 58385.

false "fix" undone as correct problem was found and fixed.

Bug #1728403: Fix a bug that CJKCodecs StreamReader hangs when it
reads a file that ends with incomplete sequence and sizehint argument
for .read() is specified.
Different versions of Berkeley DB handle this differently.
The comments and bug report should have the details. Memory is allocated
in 4.4 (and presumably earlier), but not in 4.5. Thus
4.5 has the free error, but not earlier versions.
Mostly update comments, plus make the free conditional.

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.

Complete revamp of PCBuild8 directory. Use subdirectories for each project under the main pcbuild solution. Now make extensive use of property sheets to simplify project configuration. x64 build fully supported, and the process for building PGO version (Profiler Guided Optimization) simplified. All projects are now present, except _ssl, which needs to be reimplemented. Also, some of the projects that require external libraries need extra work to fully compile on x64.

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.

be true if we didn't malloc the code? Seems like the code is wrong
or could use comments.
Also verify if the buildbots are working properly for the 2.5 branch.
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...
