In C++, it's an error to pass a string literal to a char* function
without a const_cast(). Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.
I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc. Predictably, there were a large set of functions that
needed to be fixed as a result of these changes. The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].
One cast was required as a result of the changes: A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.

mistake of passing a string like '2:59.0' to time() and getting an insane
object.

Treat comparing a date to a datetime like a mixed-type comparison.

The LaTeX is untested (well, so is the new API, for that matter).
Note that I also changed NULL to get spelled consistently in concrete.tex.
If that was a wrong thing to do, Fred should yell at me.

New include file timefuncs.h exports private API function
_PyTime_DoubleToTimet() from timemodule.c. timemodule should export
some other functions too (look for painful bits in datetimemodule.c).
Added insane-argument checking to datetime's assorted fromtimestamp()
and utcfromtimestamp() methods. Added insane-argument tests of these
to test_datetime, and insane-argument tests for ctime(), localtime()
and gmtime() to test_time.

datetime.datetime and datetime.time could yield insane objects. Thanks
to Jiwon Seo for the fix.
Bugfix candidate. I'll backport it to 2.3.

It's possible to create insane datetime objects by using the constructor
"backdoor" inserted for fast unpickling. Doing extensive range checking
would eliminate the backdoor's purpose (speed), but at least a little
checking can stop honest mistakes.

are within proper boundaries as specified in the docs.
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).
Fixes bug #897625.

The interning of short strings violates the refcnt==1 assumption for
_PyString_Resize().
A simple fix is to boost the initial value of "totalnew" by 1.
Combined with an NULL argument to PyString_FromStringAndSize(),
this assures that resulting format string is not interned.
This will remain true even if the implementation of
PyString_FromStringAndSize() changes because only the uninitialized
strings that can be interned are those of zero length.
Added a test case.

one good use: a subclass adding a method to express the duration as
a number of hours (or minutes, or whatever else you want to add). The
native breakdown into days+seconds+us is often clumsy. Incidentally
moved a large chunk of object-initialization code closer to the top of
the file, to avoid worse forward-reference trickery.

__ne__ no longer complain if they don't know how to compare to the other
thing. If no meaningful way to compare is known, saying "not equal" is
sensible. This allows things like
if adatetime in some_sequence:
and
somedict[adatetime] = whatever
to work as expected even if some_sequence contains non-datetime objects,
or somedict non-datetime keys, because they only call __eq__.
It still complains (raises TypeError) for mixed-type comparisons in
contexts that require a total ordering, such as list.sort(), use as a
key in a BTree-based data structure, and cmp().

functions. Reworked {time,datetime}_new() to do what their corresponding
setstates used to do in their state-tuple-input paths, but directly,
without constructing an object with throwaway state first. Tightened
the "is this a state tuple input?" paths to check the presumed state
string-length too, and to raise an exception if the optional second state
element isn't a tzinfo instance (IOW, check these paths for type errors
as carefully as the normal paths).

wasn't more to this than I realize!).

(pickling no longer needs them, and immutable objects shouldn't have
visible __setstate__() methods regardless). Rearranged the code to
put the internal setstate functions in the constructor sections.
Repaired the timedelta reduce() method, which was still producing
stuff that required a public timedelta.__setstate__() when unpickling.

classes have a __reduce__ that returns (self.__class__,
self.__getstate__()). tzinfo.__reduce__() is a bit smarter, calling
__getinitargs__ and __getstate__ if they exist, and falling back to
__dict__ if it exists and isn't empty.

compare against "the other" argument, we raise TypeError,
in order to prevent comparison from falling back to the
default (and worse than useless, in this case) comparison
by object address.
That's fine so far as it goes, but leaves no way for
another date/datetime object to make itself comparable
to our objects. For example, it leaves Marc-Andre no way
to teach mxDateTime dates how to compare against Python
dates.
Discussion on Python-Dev raised a number of impractical
ideas, and the simple one implemented here: when we don't
know how to compare against "the other" argument, we raise
TypeError *unless* the other object has a timetuple attr.
In that case, we return NotImplemented instead, and Python
will give the other object a shot at handling the
comparison then.
Note that comparisons of time and timedelta objects still
suffer the original problem, though.

This gives much the same treatment to datetime.fromtimestamp(stamp, tz) as
the last batch of checkins gave to datetime.now(tz): do "the obvious"
thing with the tz argument instead of a senseless thing.

checked in two days agao:
Refactoring of, and new rules for, dt.astimezone(tz).
dt must be aware now, and tz.utcoffset() and tz.dst() must not return None.
The old dt.astimezone(None) no longer works to change an aware datetime
into a naive datetime; use dt.replace(tzinfo=None) instead.
The tzinfo base class now supplies a new fromutc(self, dt) method, and
datetime.astimezone(tz) invokes tz.fromutc(). The default implementation
of fromutc() reproduces the same results as the old astimezone()
implementation, but tzinfo subclasses can override fromutc() if the
default implementation isn't strong enough to get the correct results
in all cases (for example, this may be necessary if a tzinfo subclass
models a time zone whose "standard offset" (wrt UTC) changed in some
year(s), or in some variations of double-daylight time -- the creativity
of time zone politics can't be captured in a single default implementation).

When daylight time ends, an hour repeats on the local clock (for example,
in US Eastern, the clock jumps from 1:59 back to 1:00 again). Times in
the repeated hour are ambiguous. A tzinfo subclass that wants to play
with astimezone() needs to treat times in the repeated hour as being
standard time. astimezone() previously required that such times be
treated as daylight time. There seems no killer argument either way,
but Guido wants the standard-time version, and it does seem easier the
new way to code both American (local-time based) and European (UTC-based)
switch rules, and the astimezone() implementation is simpler.

hoped it would be, but not too bad. A test had to change:
time.__setstate__() can no longer add a non-None tzinfo member to a time
object that didn't already have one, since storage for a tzinfo member
doesn't exist in that case.

into time. This is little more than *exporting* the datetimetz object
under the name "datetime", and similarly for timetz. A good implementation
of this change requires more work, but this is fully functional if you
don't stare too hard at the internals (e.g., right now a type named
"datetime" shows up as a base class of the type named "datetime"). The
docs also need extensive revision, not part of this checkin.
