Add definitions of INT_MAX and LONG_MAX to pyport.h.
Remove includes of limits.h and conditional definitions of INT_MAX
and LONG_MAX elsewhere.
This closes SourceForge patch #101659 and bug #115323.
Add the EXTENDED_ARG opcode to the virtual machine, allowing 32-bit
arguments to opcodes instead of being forced to stick to the 16-bit
limit. This is especially useful for machine-generated code, which
can be too long for the SET_LINENO parameter to fit into 16 bits.
This closes the implementation portion of SourceForge patch #100893.
fields token and expected must also be initialized, otherwise the
tests in parsetok() can generate uninitialized memory read errors.
This quiets an Insure warning.
handlers "return void", according to ANSI C.
Removed the new Py_RETURN_FROM_SIGNAL_HANDLER macro.
Left RETSIGTYPE in the config stuff, because it's not clear to
me that others aren't relying on it (e.g., extension modules).
#if RETSIGTYPE != void
That isn't C, and MSVC properly refuses to compile it.
Introduced new Py_RETURN_FROM_SIGNAL_HANDLER macro in pyport.h
to expand to the correct thing based on RETSIGTYPE. However,
only void is ANSI! Do we still have platforms that return int?
The Unix config mess appears to #define RETSIGTYPE by magic
without being asked to, so I assume it's "a problem" across
Unices still.
Work around intrcheck.c's desire to pass 'PyErr_CheckSignals' to
'Py_AddPendingCall' by providing a (static) wrapper function that has the
right number of arguments.
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").
There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)
used for indentation related errors. This patch includes Ping's
improvements for indentation-related error messages.
Closes SourceForge patches #100734 and #100856.
the number of children of a node exceeds the max possible value for
the short that is used to count them. The Python runtime converts
this parser error into the SyntaxError "expression too long."

For documentation read the comments in mymalloc.h and objimpl.h.
(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode. I'm also holding back on his
change to main.c, which seems unnecessary to me.)
signal handlers in a fork()ed child process when Python is compiled with
thread support. The bug was reported by Scott <scott@chronis.icgroup.com>.
What happens is that after a fork(), the variables used by the signal
module to determine whether this is the main thread or not are bogus,
and it decides that no thread is the main thread, so no signals will
be delivered.
The solution is the addition of PyOS_AfterFork(), which fixes the signal
module's variables. A dummy version of the function is present in the
intrcheck.c source file which is linked when the signal module is not
used.
Also grandly renamed.
Here's the new interface:
When WITH_READLINE is defined, two functions are defined:
- PyOS_GnuReadline (what used to be my_readline() with WITH_READLINE)
- PyOS_ReadlineInit (for Dave Ascher)
Always, these functions are defined:
- PyOS_StdioReadline (what used to be my_readline() without WITH_READLINE)
- PyOS_Readline (the interface used by tokenizer.c and [raw_]input().
There's a global function pointer PyOS_ReadlineFunctionPointer,
initialized to NULL. When PyOS_Readline finds this to be NULL, it
sets it to either PyOS_GnuReadline or PyOS_StdioReadline depending on
which one makes more sense (i.e. it uses GNU only if it is defined
*and* stdin is indeed a tty device).
An embedding program that has its own wishes can set the function
pointer to a function of its own design. It should take a char*
prompt argument (which may be NULL) and return a string *ending in a
\n character* -- or "" for EOF or NULL for a user interrupt.

object.h: made sizes and refcnts signed ints.
stringobject.h: make getstrsize() signed int.
methodobject.h: add METH_VARARGS and METH_FREENAME flag bit definitions.
