| | | | | | | | | PyTypeObject structures, I had to make prototypes for the functions, and move the structure definition ahead of the functions. I'd dearly like a better way to do this - to change this would make for a massive set of changes to the codebase. There's still some warnings - this is purely to get rid of errors first.

* Add const to several API functions that take char *.Jeremy Hylton2005-12-101-1/+1
| | | | | | | | | | | | | | | | | | | In C++, it's an error to pass a string literal to a char* function without a const_cast(). Rather than require every C++ extension module to put a cast around string literals, fix the API to state the const-ness. I focused on parts of the API where people usually pass literals: PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type slots, etc. Predictably, there were a large set of functions that needed to be fixed as a result of these changes. The most pervasive change was to make the keyword args list passed to PyArg_ParseTupleAndKewords() to be a const char *kwlist[]. One cast was required as a result of the changes: A type object mallocs the memory for its tp_doc slot and later frees it. PyTypeObject says that tp_doc is const char *; but if the type was created by type_new(), we know it is safe to cast to char *.

| | | | | | | | | | | | | | [ 1181301 ] make float packing copy bytes when they can which hasn't been reviewed, despite numerous threats to check it in anyway if noone reviews it. Please read the diff on the checkin list, at least! The basic idea is to examine the bytes of some 'probe values' to see if the current platform is a IEEE 754-ish platform, and if so _PyFloat_{Pack,Unpack}{4,8} just copy bytes around. The rest is hair for testing, and tests.

* SF bug #513866: Float/long comparison anomaly.Tim Peters2004-09-231-8/+206
| | | | | | | | | | | | | | | | | | When an integer is compared to a float now, the int isn't coerced to float. This avoids spurious overflow exceptions and insane results. This should compute correct results, without raising spurious exceptions, in all cases now -- although I expect that what happens when an int/long is compared to a NaN is still a platform accident. Note that we had potential problems here even with "short" ints, on boxes where sizeof(long)==8. There's #ifdef'ed code here to handle that, but I can't test it as intended. I tested it by changing the #ifdef to trigger on my 32-bit box instead. I suppose this is a bugfix candidate, but I won't backport it. It's long-winded (for speed) and messy (because the problem is messy). Note that this also depends on a previous 2.4 patch that introduced _Py_SwappedOp[] as an extern.

* staticforward bites the dust.Jeremy Hylton2002-07-171-1/+1
| | | | | | | | | | | | | | | The staticforward define was needed to support certain broken C compilers (notably SCO ODT 3.0, perhaps early AIX as well) botched the static keyword when it was used with a forward declaration of a static initialized structure. Standard C allows the forward declaration with static, and we've decided to stop catering to broken C compilers. (In fact, we expect that the compilers are all fixed eight years later.) I'm leaving staticforward and statichere defined in object.h as static. This is only for backwards compatibility with C extensions that might still use it. XXX I haven't updated the documentation.

* SF bug 525705: [2.2] underflow raise OverflowException.Tim Peters2002-03-091-2/+2
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | Try to ensure that divmod(-0.0, 1.0) -> (-0.0, +0.0) across platforms. It always did on Windows, and still does. It didn't on Linux. Alas, there's no platform-independent way to write a test case for this. Bugfix candidate.

* Enable GC for new-style instances. This touches lots of files, sinceGuido van Rossum2001-10-051-2/+6
| | | | | | | | | | | | | | | | | | | | | | many types were subclassable but had a xxx_dealloc function that called PyObject_DEL(self) directly instead of deferring to self->ob_type->tp_free(self). It is permissible to set tp_free in the type object directly to _PyObject_Del, for non-GC types, or to _PyObject_GC_Del, for GC types. Still, PyObject_DEL was a tad faster, so I'm fearing that our pystone rating is going down again. I'm not sure if doing something like void xxx_dealloc(PyObject *self) { if (PyXxxCheckExact(self)) PyObject_DEL(self); else self->ob_type->tp_free(self); } is any faster than always calling the else branch, so I haven't attempted that -- however those types whose own dealloc is fancier (int, float, unicode) do use this pattern.
