Closes SF patch #103123.
funcobject.h:
PyFunctionObject: add the func_dict slot.
funcobject.c:
PyFunction_New(): Initialize the func_dict slot to NULL.
func_getattr(): Rename to func_getattro() and change the
signature. It's more efficient to use attro methods and dig the C
string out than it is to re-convert a C string to a PyString.
Also, add support for getting the __dict__ (a.k.a. func_dict)
attribute, and for getting an arbitrary function attribute.
func_setattr(): Rename to func_setattro() and change the signature
for the same reason. Also add support for setting __dict__
(a.k.a. func_dict) and any arbitrary function attribute.
func_dealloc(): Be sure to DECREF the func_dict slot.
func_traverse(): Be sure to traverse func_dict too.
PyFunction_Type: make the necessary func_?etattro() changes.
classobject.c:
instancemethod_memberlist: Add __dict__
instancemethod_setattro(): New method to set arbitrary attributes
on methods (really the underlying im_func). Raise TypeError when
the instance is bound or when you're trying to set one of the
reserved im_* attributes.
instancemethod_getattr(): Renamed to instancemethod_getattro()
since that's what it really is. Also, added support fo getting
arbitrary attributes through the im_func.
PyMethod_Type: Do the ?etattr{,o} dance.
regardless of whether the system getopt() does what we want. This avoids the
hassle with prototypes and externs, and the check to see if the system
getopt() does what we want. Prefix optind, optarg and opterr with _PyOS_ to
avoid name clashes. Add new include file to define the right symbols. Fix
Demo/pyserv/pyserv.c to include getopt.h itself, instead of relying on
Python to provide it.
#define'd to an unreasonable value (several recent gcc systems have
misdefined it, causing bogus overflows in integer multiplication). Nuke
CHAR_BIT entirely.
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 three new convenience functions to the PyModule_*() family:
PyModule_AddObject(), PyModule_AddIntConstant(), PyModule_AddStringConstant().
This closes SourceForge patch #101233.
Note a curious extension to the std C rules: x, X and o formatting can never produce
a sign character in C, so the '+' and ' ' flags are meaningless for them. But
unbounded ints *can* produce a sign character under these conversions (no fixed-
width bitstring is wide enough to hold all negative values in 2's-comp form). So
these flags become meaningful in Python when formatting a Python long which is too
big to fit in a C long. This required shuffling around existing code, which hacked
x and X conversions to death when both the '#' and '0' flags were specified: the
hacks weren't strong enough to deal with the simultaneous possibility of the ' ' or
'+' flags too, since signs were always meaningless before for x and X conversions.
Isomorphic shuffling was required in unicodeobject.c.
Also added dozens of non-trivial new unbounded-int test cases to test_format.py.
which implements the automatic conversion from Unicode to a string
object using the default encoding.
The new API is then put to use to have eval() and exec accept
Unicode objects as code parameter. This closes bugs #110924
and #113890.
As side-effect, the traditional C APIs PyString_Size() and
PyString_AsString() will also accept Unicode objects as
parameters.
I can't test this, so I'm just checking it in with blind faith in Andy.
I've tested that it doesn't broeak a non-Pth build on Linux.
Changes include:
- There's a --with-pth configure option.
- Instead of _GNU_PTH, we test for HAVE_PTH.
- Better signal handling.
- (The config.h.in file is regenerated in a slightly different order.)
It's hard to sort out what the bug was, exactly. So, Big Hammer:
1. Python shouldn't be in the business of #define'ing NULL, period.
2. Users of the Python C API shouldn't be in the business of not including
Python.h, period.
Hence:
1. Removed all #define's of NULL in Python source code (pyport.h and
object.h).
2. Since we're *relying* on stdio.h defining NULL, put an #error in
Python.h after its #include of stdio.h if NULL isn't defined then.
PyRun_FileEx(). These are the same as their non-Ex counterparts but
have an extra argument, a flag telling them to close the file when
done.
Then this is used by Py_Main() and execfile() to close the file after
it is parsed but before it is executed.
Adding APIs seems strange given the feature freeze but it's the only
way I see to close the bug report without incompatible changes.
[ Bug #110616 ] source file stays open after parsing is done (PR#209)
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.
by the following.
typedef in a portable way the Python name for the C9X uintptr_t type.
This latter is the most portable way to spell an integral type to
which a void* can be cast to and back again without losing
information. Parallel checkin hacks configure to check if the
platform/compiler supports the C9X name.
name as n'. By doing some twists and turns, "as" is not a reserved word.
There is a slight change in semantics for 'from module import name' (it will
now honour the 'global' keyword) but only in cases that are explicitly
undocumented.
This was a misleading bug -- the true "bug" was that hash(x) gave an error
return when x is an infinity. Fixed that. Added new Py_IS_INFINITY macro to
pyport.h. Rearranged code to reduce growing duplication in hashing of float and
complex numbers, pushing Trent's earlier stab at that to a logical conclusion.
Fixed exceedingly rare bug where hashing of floats could return -1 even if there
wasn't an error (didn't waste time trying to construct a test case, it was simply
obvious from the code that it *could* happen). Improved complex hash so that
hash(complex(x, y)) doesn't systematically equal hash(complex(y, x)) anymore.
did the same anyway.
I'm not sure what to do with Tools/compiler/compiler/* -- that isn't part of
distutils, is it ? Should it try to be compatible with old bytecode version ?
the Python Unicode implementation.
The internal buffer used for implementing the buffer protocol
is renamed to defenc to make this change visible. It now holds the
default encoded version of the Unicode object and is calculated
on demand (NULL otherwise).
Since the default encoding defaults to ASCII, this will mean that
Unicode objects which hold non-ASCII characters will no longer
work on C APIs using the "s" or "t" parser markers. C APIs must now
explicitly provide Unicode support via the "u", "U" or "es"/"es#"
parser markers in order to work with non-ASCII Unicode strings.
(Note: this patch will also have to be applied to the 1.6 branch
of the CVS tree.)
This doesn't change the copyright status for these files -- just the
markings! Doing it on the main branch for these three files for which
the HEAD revision was pushed back into 1.6.
for systems that are missing those declarations from system include files.
Start by moving a pointy-haired ones from their previous locations to the
new section.
(The gethostname() one, for instance, breaks on several systems, because
some define it as (char *, size_t) and some as (char *, int).)
I purposely decided not to include the summary of used #defines like Tim did
in the first section of pyport.h. In my opinion, the number of #defines
likedly to be used by this section would make such an overview unwieldy. I
would suggest documenting the non-obvious ones, though.
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).
good C practice hasn't been available to everything all along.
Added Py_SAFE_DOWNCAST(VALUE, WIDE, NARROW) macro to pyport.h; this
just casts VALUE from type WIDE to type NARROW, but assert-fails if
Py_DEBUG is defined and info is lost due to casting.
Replaced a line in Fredrik's fix to marshal.c to use the new macro.
#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.
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 ;)

This was a convenient excuse to create the pyport.h file recently
discussed!
Please use new Py_ARITHMETIC_RIGHT_SHIFT when right-shifting a
signed int and you *need* sign-extension. This is #define'd in
pyport.h, keying off new config symbol SIGNED_RIGHT_SHIFT_ZERO_FILLS.
If you're running on a platform that needs that symbol #define'd,
the std tests never would have worked for you (in particular,
at least test_long would have failed).
The autoconfig stuff got added to Python after my Unix days, so
I don't know how that works. Would someone please look into doing
& testing an auto-config of the SIGNED_RIGHT_SHIFT_ZERO_FILLS
symbol? It needs to be defined if & only if, e.g., (-1) >> 3 is
not -1.
Stein -- thanks!). Incidentally removed all the Py_PROTO macros
from object.h, as they prevented my editor from magically finding
the definitions of the "coercion", "cmpfunc" and "reprfunc"
typedefs that were being redundantly applied in longobject.c.

to be able to reuse the existing Unicode codecs for string
purposes too.
Conversion from string to Unicode and back are done using the

These #defines are documented in e.g. the file /usr/include/features.h

setup is more usable than the old one -- and turns out it is (for
whatever reason, it was impossible to do a commit before that
involved more than one directory).

The macros are currently implemented using the existing is* tables
but will have to be updated to meet the Unicode standard definitions
(add tables for non-cased letters and letter modifiers).
