Neil Schemenauer 156910851e Hide GCC attributes fom compilers that don't support them. 2001-10-23 02:20:37 +00:00
Tim Peters 092a7a80fd SF patch [#466353] Py_HUGE_VAL on BeOS for Intel.
The patch repaired internal gcc compiler errors on BeOS.
This checkin repairs them in a simpler way, by explicitly casting the
platform INFINITY to double.

Tim Peters a40c793d06 Rework the way we try to check for libm overflow, given that C99 no longer
requires that errno ever get set, and it looks like glibc is already
playing that game.  New rules:

+ Never use HUGE_VAL.  Use the new Py_HUGE_VAL instead.

+ Never believe errno.  If overflow is the only thing you're interested in,
  use the new Py_OVERFLOWED(x) macro.  If you're interested in any libm
  errors, use the new Py_SET_ERANGE_IF_OVERFLOW(x) macro, which attempts
  to set errno the way C89 said it worked.

Unfortunately, none of these are reliable, but they work on Windows and I
*expect* under glibc too.

Tim Peters 57f282a2a0 Try to recover from that glibc's ldexp apparently doesn't set errno on
overflow.  Needs testing on Linux (test_long.py and test_long_future.py
especially).

Tim Peters 79248aa1e4 SF bug [#456252] Python should never stomp on [u]intptr_t.
pyport.h:  typedef a new Py_intptr_t type.
    DELICATE ASSUMPTION:  That HAVE_UINTPTR_T implies intptr_t is
    available as well as uintptr_t.  If that turns out not to be
    true, things must get uglier (C99 wants both, so I think it's
    an assumption we're *likely* to get away with).
thread_nt.h, PyThread_start_new_thread:  MS _beginthread is documented
    as returning unsigned long; no idea why uintptr_t was being used.
Others:  Always use Py_[u]intptr_t, never [u]intptr_t directly.

Tim Peters 8a267b62cc Remove 6-year old hack to worm around a bug in "NextSpec/Sparc 3.3
pre-release limits.h".

Martin v. Löwis 4f1cd8bdcb Patch #411138: Rename config.h to pyconfig.h. Closes bug #231774. 2001-07-26 13:41:06 +00:00

Thomas Wouters 76b642d28a Remove include-file-dependant half-prototype of clnt_create(). 2001-01-22 16:50:11 +00:00
Thomas Wouters e75e6d06d2 Move declaration of 'clnt_create()' NIS function to pyport.h, as it's
supposed to be declared in system include files (with a proper prototype.)
Should be moved to a platform-specific block if anyone finds out which
broken platforms need it :-)
2001-01-21 23:34:12 +00:00
Tim Peters 60f42b50d8 Move distributed and duplicated config for stat() and fstat() into pyport.h. 2001-01-18 03:03:16 +00:00
Andrew M. Kuchling 234fb632a3 Change LONG_BIT error warning to mention glibc, too, since this is really
a glibc, not a gcc, problem.
2001-01-12 15:06:28 +00:00
Marc-André Lemburg 77317ca7dc Added Py_FPROTO macro which was available in Python 1.5.x and below.
This should not be used for new code, but will probably make porting
old extensions to 2.0 a lot easier.

Also see Bug #116011.
2000-10-05 17:25:45 +00:00
Tim Peters d57731f74b Move LONG_BIT from intobject.c to pyport.h. #error if it's already been
#define'd to an unreasonable value (several recent gcc systems have
misdefined it, causing bogus overflows in integer multiplication).  Nuke
CHAR_BIT entirely.
2000-10-05 01:42:25 +00:00
Fred Drake d5fadf75e4 Rationalize use of limits.h, moving the inclusion to Python.h.
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.

Tim Peters 4826a894c5 Close SF bug 110826: a complaint about the way Python #define'd NULL.
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.

Tim Peters 1a2eefdc4f A #define didn't start in column 1. Closes SF bug 113888. 2000-09-08 15:45:34 +00:00
Vladimir Marangozov e2bf7e63d6 Add missing Py_PROTO macro for backward compatibility with old extensions
(sources) which may still use it and now fail to compile.
Reported by M-A Lemburg.  Closes [ Bug #113576 ].

Guido van Rossum 8586991099 REMOVED all CWI, CNRI and BeOpen copyright markings.
This should match the situation in the 1.6b1 tree.

Barry Warsaw fd847b23e6 Moved LONG_LONG #define from longobject.h to here, since it's needed
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.

Tim Peters 39dce29365 Fix for http://sourceforge.net/bugs/?func=detailbug&bug_id=111866&group_id=5470.
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.

Vladimir Marangozov 2c57e076fe #include reordering so that extern "C" does not interfere with
standard C++ specific includes.

Peter Schneider-Kamp 10e1bf2f64 remove all occurence of math.rint() from the sources
(and yes, "Currintly" also counts <0.5 wink>)

Guido van Rossum 367e46a943 Of course, you meant "#if 0" and not "#ifdef 0". :) 2000-08-01 18:28:44 +00:00

Sjoerd Mullender 0765fe3a05 Make mode_t available for the declaration of _getpty(). 2000-07-26 15:46:29 +00:00
Thomas Wouters 1e0c2f4bee Create a new section of pyport.h to hold all external function declarations
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.

Tim Peters 4f1b2081e9 Removed all instances of RETSIGTYPE from the source code: signal
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).
2000-07-23 21:18:09 +00:00
Tim Peters 8315ea5790 Included assert.h in Python.h -- it's absurd that this basic tool of
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.
2000-07-23 19:28:35 +00:00
Tim Peters 1be46844d9 Recent ANSIfication introduced a couple instances of
#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.
2000-07-23 18:10:18 +00:00
Vladimir Marangozov 14a4d88a2e Remove the "1" that Tim sticked to the preprocessor symbol for unknown reasons
(cf. the rest of the headers in the distribution)

Tim Peters 7d3a511a40 Cray J90 fixes for long ints.
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.
