This can break possible code (datetime module needed changing, for instance)
that uses 0 for values that need to be greater 1 or greater (month, day, and
day of year).

(As an experiment, I'm adding a line that #undefs HAVE_STRPTIME,
so that you'll always get the Python version. This is so that it
gets some good exercise. We should eventually delete that line.)
type.__module__ behavior.
This adds the module name and a dot in front of the type name in every
type object initializer, except for built-in types (and those that
already had this). Note that it touches lots of Mac modules -- I have
no way to test these but the changes look right. Apologies if they're
not. This also touches the weakref docs, which contains a sample type
object initializer. It also touches the mmap test output, because the
mmap type's repr is included in that output. It touches object.h to
put the correct description in a comment.
This is a big one, touching lots of files. Some of the platforms
aren't tested yet. Briefly, this changes the return value of the
os/posix functions stat(), fstat(), statvfs(), fstatvfs(), and the
time functions localtime(), gmtime(), and strptime() from tuples into
pseudo-sequences. When accessed as a sequence, they behave exactly as
before. But they also have attributes like st_mtime or tm_year. The
stat return value, moreover, has a few platform-specific attributes
that are not available through the sequence interface (because
everybody expects the sequence to have a fixed length, these couldn't
be added there). If your platform's struct stat doesn't define
st_blksize, st_blocks or st_rdev, they won't be accessible from Python
either.
(Still missing is a documentation update.)
ctime, gmtime and localtime optional, defaulting to 'the current time' in
all cases. Adjust docs, add news item. Also convert all argument-handling to
METH_VARARGS. Closes SF patch #103265.
Py_FatalError() from module initialization functions. The importing
mechanism already checks for PyErr_Occurred() after module importation
and it Does The Right Thing.
Unfortunately, the following either were not compiled or tested by the
regression suite, due to issues with my development platform:
almodule.c
cdmodule.c
mpzmodule.c
puremodule.c
timingmodule.c
Minor updates for BeOS R5.
Use of OSError in test.test_fork1 changed to TestSkipped, with corresponding
change in BeOS/README (by Fred).
This closes SourceForge patch #100978.
and a couple of functions that were missed in the previous batches. Not
terribly tested, but very carefully scrutinized, three times.
All these were found by the little findkrc.py that I posted to python-dev,
which means there might be more lurking. Cases such as this:
long
func(a, b)
long a;
long b; /* flagword */
{
and other cases where the last ; in the argument list isn't followed by a
newline and an opening curly bracket. Regexps to catch all are welcome, of
course ;)
This patch fixes a possible overflow in the Sleep system call on
Win32/64 in the time_sleep() function in the time module. For very
large values of the give time to sleep the number of milliseconds can
overflow and give unexpected sleep intervals. THis patch raises an
OverflowError if the value overflows.
Closes SourceForge patch #100514.
Mark Hammond provided (a long time ago) a better Win32 specific
time_clock implementation in timemodule.c. The library for this
implementation does not exist on Win64 (yet, at least). This patch
makes Win64 fall back on the system's clock() function for
time_clock().
This closes SourceForge patch #100512.
This patch is a workaround for Macintosh, where the GUSI I/O library
(time, stat, etc) use the MacOS epoch of 1-Jan-1904 and the MSL C
library (ctime, localtime, etc) uses the (apparently ANSI standard)
epoch of 1-Jan-1900. Python programs see the MacOS epoch and we
convert values when needed.

calls Py_BLOCK_THREADS anyway. The change moves Py_BLOCK_THREADS
to inside the if, so it's only executed when the function
actually returns unexpectedly.
only. Through some mysterious interaction, they would take 9 separate
arguments as well. This misfeature is now disabled (to end a
difference with JPython).
The test really wanted to distinguish between the two. So now we test
for __GLIBC__ instead. I have confirmed that this works for glibc and
I have an email from Christian Tanzer confirming that it works for
libc5, so it should be fine.
"""
The GNU folks, in their infinite wisdom, have decided not to implement
altzone in libc6; this would not be horrible, except that timezone
(which is implemented) includes the current DST setting (i.e. timezone
for Central is 18000 in summer and 21600 in winter). So Python's
timezone and altzone variables aren't set correctly during DST.
Here's a patch relative to 1.5.2b2 that (a) makes timezone and altzone
show the "right" thing on Linux (by using the tm_gmtoff stuff
available in BSD, which is how the GLIBC manual claims things should
be done) and (b) should cope with the southern hemisphere. In pursuit
of (b), I also took the liberty of renaming the "summer" and "winter"
variables to "july" and "jan". This patch should also make certain
time calculations on Linux actually work right (like the tz-aware
functions in the rfc822 module).
(It's hard to find DST that's currently being used in the southern
hemisphere; I tested using Africa/Windhoek.)

He writes:
I had an off-by-1000 error in floatsleep(),
and the problem with time.clock() is that it's not implemented properly
on QNX... ANSI says it's supposed to return _CPU_ time used by the
process, but on QNX it returns the amount of real time used... so I was
confused.
guessing what happened when strftime() returns 0. Is it buffer
overflow or was the result simply 0 bytes long? (This happens for an
empty format string, or when the format string is a single %Z and the
timezone is unknown.) if the buffer is at least 256 times as long as
the format, assume the latter.
2-digit years are now converted using rules that are (according to
Fredrik Lundh) recommended by POSIX or X/Open: 0-68 mean 2000-2068,
69-99 mean 1969-1999.
2-digit years are now only accepted if time.accept2dyear is set to a
nonzero integer; if it is zero or not an integer or absent, only year
values >= 1900 are accepted. Year values 100-1899 and negative year
values are never accepted.
The initial value of time.accept2dyear depends on the environment
variable PYTHONY2K: if PYTHONY2K is set and non-empty,
time.accept2dyear is initialized to 0; if PYTHONY2K is empty or not
set, time.accept2dyear is initialized to 0.
to inside floatsleep(). This is necessary because floatsleep() does
the error handling and it must have grabbed the interpreter lock and
thread state before it can do so.
