CHAR_MAX, use hardcoded -128 and 127. This may seem strange, unless
you realize that we're talking about signed bytes here! Bytes are
always 8 bits and 2's complement. CHAR_MIN and CHAR_MAX are
properties of the char data type, which is guaranteed to hold at least
8 bits anyway.
Otherwise you'd get failing tests on platforms where unsigned char is
the default (e.g. AIX).
Thanks, Vladimir Marangozov, for finding this nit!
what the dozen+ subprojects are for, which are and aren't
expected to build out of the box, and what else is needed to get
them all to build. Also explained that Alpha configurations
don't refer to pre-beta, but to the Alpha processor! That's
baffled me for years <0.7 wink>.
This'll work fine with 2.0 or 1.5.2, but is less than ideal for
1.6a1/a2. But the code to accomodate 1.6a1/a2 was released with
Distutils 0.9, so it can go away now.

Fix PC/msvcrtmodule.c and PC/winreg.c for Win64. Basically:
- sizeof(HKEY) > sizeof(long) on Win64, so use PyLong_FromVoidPtr()
instead of PyInt_FromLong() to return HKEY values on Win64
- Check for string overflow of an arbitrary registry value (I know
that ensuring that a registry value does not overflow 2**31 characters
seems ridiculous but it is *possible*).
Closes SourceForge patch #100517.
allows the caller to execute the various tests in pseudo-random order -
default is still to execute tests in the order returned by findtests().
* moved initialization of the various flag variables to the main() function
definition, making it possible to execute regrtest.main() interactively
and still override default behavior.
disables it. The gc test is moved to just after the thread test, as
is the wctype-functions test.
Modules/Setup.config is generated instead of Modules/Setup.thread.
Applied SF patch #100684 (loewis) to fix help alignment bug.
The common technique for printing out a pointer has been to cast to a long
and use the "%lx" printf modifier. This is incorrect on Win64 where casting
to a long truncates the pointer. The "%p" formatter should be used instead.
The problem as stated by Tim:
> Unfortunately, the C committee refused to define what %p conversion "looks
> like" -- they explicitly allowed it to be implementation-defined. Older
> versions of Microsoft C even stuck a colon in the middle of the address (in
> the days of segment+offset addressing)!
The result is that the hex value of a pointer will maybe/maybe not have a 0x
prepended to it.
Notes on the patch:
There are two main classes of changes:
- in the various repr() functions that print out pointers
- debugging printf's in the various thread_*.h files (these are why the
patch is large)
Closes SourceForge patch #100505.
This patch fixes possible overflow in the use of
PyOS_GetLastModificationTime in getmtime.c and Python/import.c.
Currently PyOS_GetLastModificationTime returns a C long. This can
overflow on Win64 where sizeof(time_t) > sizeof(long). Besides it
should logically return a time_t anyway (this patch changes this).
As well, import.c uses PyOS_GetLastModificationTime for .pyc
timestamping. There has been recent discussion about the .pyc header
format on python-dev. This patch adds oveflow checking to import.c so
that an exception will be raised if the modification time
overflows. There are a few other minor 64-bit readiness changes made
to the module as well:
- size_t instead of int or long for function-local buffer and string
length variables
- one buffer overflow check was added (raises an exception on possible
overflow, this overflow chance exists on 32-bit platforms as well), no
other possible buffer overflows existed (from my analysis anyway)
Closes SourceForge patch #100509.
