Neal Norwitz 3dd8be414e Get Py_DEPRECATED to work with gcc 4.x too 2006-03-20 06:33:01 +00:00
Tim Peters ae1d0c978d Introduced symbol PY_FORMAT_SIZE_T. See the new comments
in pyport.h.  Changed PyString_FromFormatV() to use it
instead of inlining its own maze of #if'ery.

Martin v. Löwis 2d65b5542b Fix intptr_t fallback for Py_ssize_t. 2006-02-18 18:26:55 +00:00
Martin v. Löwis 18e165558b Merge ssize_t branch. 2006-02-15 17:27:45 +00:00
Neal Norwitz 358d938aaa Remove INT_MIN that came from the AST merge.
INT_MIN is used in Python/compile.c, but it was also used
in Objects/abstract.c Python/getargs.c.  If we need it for compile.c,
we can get it from the same place as the other files.

Jeremy Hylton 3e0055f8c6 Merge ast-branch to head
This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.

The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.

Guido van Rossum 539c662f10 - Changes donated by Elemental Security to make it work on HP-UX 11 on
Itanium2 with HP's 64-bit compiler (SF patch #1225212).

Tim Peters 862f0593d8 Introduced a Py_IS_NAN macro, which probably works on the major platforms
today.  pyconfig.h can override it if not, and can also override
Py_IS_INFINITY now.  Py_IS_NAN and Py_IS_INFINITY are overridden now
for Microsoft compilers, using efficient MS-specific spellings.

Hye-Shik Chang b5047fd019 Add a workaround for a problem that UTF-8 strings can be corrupted
or broken by basic ctype functions in 4.4BSD descendants.  This
will be fixed in their future development branches but they'll keep
the POSIX-incompatibility for their backward-compatiblities in near
future.

Jason Tishler 6bc06eca70 Bug #794140: cygwin builds do not embed
The embed2.diff patch solves the user's problem by exporting the missing
symbols from the Python core so Python can be embedded in another Cygwin
application (well, at lest vim).

Jason Tishler 3076559ea5 This patch enables the building of Cygwin Python with a static core
which still supports shared extensions. It takes advantage the latest
Cygwin binutils (i.e., 20030901-1) which can export symbols from
executables:

http://cygwin.com/ml/cygwin-announce/2003-09/msg00002.html

Additionally, it finally lays to rest the following mailing list
subthread:

http://mail.python.org/pipermail/python-list/2002-May/102500.html

I tested the patch under Red Hat Linux 8.0 too

Jason Tishler fb8595df4f Patch #661760: Cygwin auto-import module patch
The attached patch enables shared extension
modules to build cleanly under Cygwin without
moving the static initialization of certain function
pointers (i.e., ones exported from the Python
DLL core) to a module initialization function.

Additionally, this patch fixes the modules that
have been changed in the past to accommodate
Cygwin.

Tim Peters 4643bd9a9c Apparently FreeBSD enables some HW floating-point exceptions by default.
This can cause core dumps when Python runs.  Python relies on the 754-
(and C99-) mandated default "non-stop" mode for FP exceptions.  This
patch from Ben Laurie disables at least one FP exception on FreeBSD at
Python startup time.

Neal Norwitz 802926482c Provide mechanism to deprecate functions, types, and struct members.
It would be nice to support other compilers besides gcc.

Neil Schemenauer 96aa0acef0 Use Py_GCC_ATTRIBUTE instead of __attribute__. Compilers other than GCC
might use __attribute__ in other ways (e.g. CodeWarrior).

Mark Hammond a290527376 Excise DL_IMPORT/EXPORT from object.h, and related files. This patch
also adds 'extern' to PyAPI_DATA rather than at each declaration, as
discussed with Tim and Guido.

Tim Peters 1de41bfbc0 Stop trying to cater to platforms with a broken HUGE_VAL definition. It
breaks other platforms (in this case, the hack for broken Cray systems in
turn caused failure on a Mac system broken in a different way).

Jason Tishler bc48826dc2 Patch #555929: Cygwin AH_BOTTOM cleanup patch (*** version 2 ***)
This patch complies with the following request found
near the top of configure.in:

# This is for stuff that absolutely must end up in pyconfig.h.
# Please use pyport.h instead, if possible.

I tested this patch under Cygwin, Win32, and Red
Hat Linux. Python built and ran successfully on
each of these platforms.

Tim Peters af3e8de580 First stab at rationalizing the PyMem_ API. Mixing PyObject_xyz with
PyMem_{Del, DEL} doesn't work yet (compilation problems).

pyport.h:  _PyMem_EXTRA is gone.

pmem.h:  Repaired comments.  PyMem_{Malloc, MALLOC} and
PyMem_{Realloc, REALLOC} now make the same x-platform guarantees when
asking for 0 bytes, and when passing a NULL pointer to the latter.

object.c:  PyMem_{Malloc, Realloc} just call their macro versions
now, since the latter take care of the x-platform 0 and NULL stuff
by themselves now.

pypcre.c, grow_stack():  So sue me.  On two lines, this called
PyMem_RESIZE to grow a "const" area.  It's not legit to realloc a
const area, so the compiler warned given the new expansion of
PyMem_RESIZE.  It would have gotten the same warning before if it
had used PyMem_Resize() instead; the older macro version, but not the
function version, silently cast away the constness.  IMO that was a wrong
thing to do, and the docs say the macro versions of PyMem_xyz are
deprecated anyway.  If somebody else is resizing const areas with the
macro spelling, they'll get a warning when they recompile now too.

Tim Peters dc5a508761 SF bug 525705: [2.2] underflow raise OverflowException.
Another year in the quest to out-guess random C behavior.

Added macros Py_ADJUST_ERANGE1(X) and Py_ADJUST_ERANGE2(X, Y).  The latter
is useful for functions with complex results.  Two corrections to errno-
after-libm-call are attempted:

1. If the platform set errno to ERANGE due to underflow, clear errno.
   Some unknown subset of libm versions and link options do this.  It's
   allowed by C89, but I never figured anyone would do it.

2. If the platform did not set errno but overflow occurred, force
   errno to ERANGE.  C89 required setting errno to ERANGE, but C99
   doesn't.  Some unknown subset of libm versions and link options do
   it the C99 way now.

Bugfix candidate, but hold off until some Linux people actually try it,
with and without -lieee.  I'll send a help plea to Python-Dev.

Tim Peters a5d78cc208 Whether platform malloc(0) returns NULL has nothing to do with whether
platform realloc(p, 0) returns NULL, so MALLOC_ZERO_RETURNS_NULL can
be correctly undefined yet realloc(p, 0) can return NULL anyway.

Prevent realloc(p, 0) doing free(p) and returning NULL via a different
hack.  Would probably be better to get rid of MALLOC_ZERO_RETURNS_NULL
entirely.

Bugfix candidate.

Tim Peters 10a3bb53a8 SF bug #495548: troublesome #define in pyport.h
Removed the ancient "#define ANY void".

Bugfix candidate?  Hard call.  The bug report claims the existence of
this #define creates conflicts with other packages, which is easy to
believe.  OTOH, some extension authors may still be relying on its
presence.  I'm afraid you can't win on this one.

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

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.
