| | | | | lining killed performance on certain Intel boxes, and the "aggressive" macro itself gives most of the benefits on others.

* Added a new macro, Py_IS_FINITE(X). On windows there is an intrinsic for ↵Kristján Valur Jónsson2006-05-251-0/+9

| | | | | linux with gcc 4.0.2, after talking to Tim. <ymmit> But it won't break anything anywhere, so don't worry :-)

* Introduced symbol PY_FORMAT_SIZE_T. See the new commentsTim Peters2006-03-171-0/+39
| | | | | in pyport.h. Changed PyString_FromFormatV() to use it instead of inlining its own maze of #if'ery.

* Remove INT_MIN that came from the AST merge.Neal Norwitz2005-10-211-1/+0
| | | | | | 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.
* Merge ast-branch to headJeremy Hylton2005-10-201-0/+1
| | | | | | | | | | 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.

* Bug #794140: cygwin builds do not embedJason Tishler2003-09-041-1/+6
| | | | | | 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).
* This patch enables the building of Cygwin Python with a static coreJason Tishler2003-09-041-1/+2
| | | | | | | | | | | | | | | 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

* Patch #661760: Cygwin auto-import module patchJason Tishler2003-01-061-1/+5
| | | | | | | | | | | | 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.
* Apparently FreeBSD enables some HW floating-point exceptions by default.Tim Peters2002-12-281-5/+10
| | | | | | | 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.

* Provide mechanism to deprecate functions, types, and struct members.Neal Norwitz2002-12-191-0/+13
| | | | It would be nice to support other compilers besides gcc.
* Use Py_GCC_ATTRIBUTE instead of __attribute__. Compilers other than GCCNeil Schemenauer2002-09-151-1/+3
| | | | might use __attribute__ in other ways (e.g. CodeWarrior).
* Excise DL_IMPORT/EXPORT from object.h, and related files. This patchMark Hammond2002-07-291-3/+3
| | | | | also adds 'extern' to PyAPI_DATA rather than at each declaration, as discussed with Tim and Guido.

* Stop trying to cater to platforms with a broken HUGE_VAL definition. ItTim Peters2002-07-031-12/+7
| | | | | 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).

* First stab at rationalizing the PyMem_ API. Mixing PyObject_xyz withTim Peters2002-04-121-22/+0
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* SF bug 525705: [2.2] underflow raise OverflowException.Tim Peters2002-03-091-0/+35
| | | | | | | | | | | | | | | | | | | | 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.
* Whether platform malloc(0) returns NULL has nothing to do with whetherTim Peters2002-03-021-2/+10
| | | | | | | | | | | 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.
* OS/2 EMX port changes (Include part of patch #450267):Andrew MacIntyre2002-02-261-0/+3
| | | | | | Include/ osdefs.h // EMX promotes Un*x path separators pyport.h
* Got rid of a few more NeXT ifdefs. The last, I think.Jack Jansen2002-02-011-2/+1
