Tkinter. This adds a separate lock -- read the comments. (This was
also needed for Mark Hammond's attempts to make PythonWin
Tkinter-friendly.)
The changes have affected the EventHook slightly, too; and I've done
some more cleanup of the code that deals with the different versions
of Tcl_CreateFileHandler().
- Handle <? processing instructions >.
- Allow . and - in entity names.
Also fixed an oversight in the previous fix (in one place, [ \t\r\n]
was used instead of string.whitespace).
so that our #ifdef test has the wrong effect. Substitute hardcoded
values for some important symbols (but not for the whole range -- some
are pretty obscure so it's not worth it).
control before TrackControl is called. The default implementation
calls TrackControl and then do_controlhit().
For ScrolledWindow, do_rawcontrol passes a tracker function to
TrackControl if the mouse is in one of the arrows or grey areas, and
the tracker handles scrolling. For the thumb part nothing has changed.

Guido, the overflow checking in PyLong_AsLong is off a little:
1) If the C in use sign-extends right shifts on signed longs, there's a
spurious overflow error when converting the most-negative int:

>>> x = -1L << 31
>>> x
-2147483648L
>>> int(x)
Traceback (innermost last):
File "<stdin>", line 1, in ?
OverflowError: long int too long to convert
>>>
2) If C does not sign-extend, some genuine overflows won't be caught.
The attached should repair both, and, because I installed a new disk and a C
compiler today, it's even been compiled this time <wink>.

Also, here is a new version of import_nt.c, which allows you to register a
Debug module in the registry. While I was there I removed some of the
ugliness - what was I thinking :-)
registers an input file handler for stdin with Tcl and handles Tcl
events until something is available on stdin; it then deletes the
handler and returns from EventHook().
This works with or without GNU readline, and doesn't busy-wait.
It still doesn't work for Mac or Windows :-(
Rationalized the doc strings.
Also simplify the module initialization -- we don't need a __version__
which is set to "$Rev" :-) and we don't need a fatal error when the
initialization fails.
Make sure that no tp_as_numbers->nb_<whatever> function is called
without checking for a NULL pointer. Marc-Andre Lemburg will love it!
(Except that he's just rewritten all this code for a different
approach to coercions ;-( )

Also make sure that no use of a function pointer gotten from a
tp_as_sequence or tp_as_mapping structure is made without checking it
for NULL first.
the code here becomes much simpler. In particular: abs(), divmod(),
pow(), int(), long(), float(), len(), tuple(), list().

A few other cosmetic things, such as properly reindenting slice().
programming style.
Recoded many routines to incorporate better error checking, and/or
better versions of the same function found elsewhere
(e.g. bltinmodule.c or ceval.c). In particular,
Py_Number_{Int,Long,Float}() now convert from strings, just like the
built-in functions int(), long() and float().
Sequences and mappings are now safe to have NULL function pointers
anywhere in their tp_as_sequence or tp_as_mapping fields. (A few
places in other files need to be checked in too.)
Renamed PySequence_In() to PySequence_Contains().
old value in a temporary and XDECREF it only after then new value has
been set. This prevents the (unlikely) case where the destructor of
the member uses the containing object -- it would find it in an
undefined state.
