* Add warning mode for classic division, almost exactly as specified inGuido van Rossum2001-08-319-25/+146
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PEP 238. Changes: - add a new flag variable Py_DivisionWarningFlag, declared in pydebug.h, defined in object.c, set in main.c, and used in {int,long,float,complex}object.c. When this flag is set, the classic division operator issues a DeprecationWarning message. - add a new API PyRun_SimpleStringFlags() to match PyRun_SimpleString(). The main() function calls this so that commands run with -c can also benefit from -Dnew. - While I was at it, I changed the usage message in main() somewhat: alphabetized the options, split it in *four* parts to fit in under 512 bytes (not that I still believe this is necessary -- doc strings elsewhere are much longer), and perhaps most visibly, don't display the full list of options on each command line error. Instead, the full list is only displayed when -h is used, and otherwise a brief reminder of -h is displayed. When -h is used, write to stdout so that you can do `python -h | more'. Notes: - I don't want to use the -W option to control whether the classic division warning is issued or not, because the machinery to decide whether to display the warning or not is very expensive (it involves calling into the warnings.py module). You can use -Werror to turn the warnings into exceptions though. - The -Dnew option doesn't select future division for all of the program -- only for the __main__ module. I don't know if I'll ever change this -- it would require changes to the .pyc file magic number to do it right, and a more global notion of compiler flags. - You can usefully combine -Dwarn and -Dnew: this gives the __main__ module new division, and warns about classic division everywhere else.
* Fix a memory leak in str_subtype_new(). (All the otherGuido van Rossum2001-08-311-3/+3
| | | | xxx_subtype_new() functions are OK, but I goofed up in this one. :-( )

* Give 'super' a decent repr(), and readonly attributes to access theGuido van Rossum2001-08-301-11/+36

* SF bug #456621: normpath on Win32 not collapsing c:\\..Tim Peters2001-08-302-8/+35
| | | | | | I actually rewrote normpath quite a bit: it had no test cases, and as soon as I starting writing some I found several cases that didn't make sense.

* metaclass(): add some more examples of metaclasses, including oneGuido van Rossum2001-08-301-0/+104

* SF patch #455966: Allow leading 0 in float/imag literals.Tim Peters2001-08-305-15/+84
| | | | Consequences for Jython still unknown (but raised on Jython-Dev).
* PyObject_Repr(): add missing ">" back at end of format string: "<%sGuido van Rossum2001-08-301-1/+1

* Fix _convert_NAME() so that it doesn't store locals for class bodies.Jeremy Hylton2001-08-306-30/+30
| | | | | | | | | Fix list comp code generation -- emit GET_ITER instead of Const(0) after the list. Add CO_GENERATOR flag to generators. Get CO_xxx flags from the new module

| | | | | | | | | | | | __dict__ slot for string subtypes. subtype_dealloc(): properly use _PyObject_GetDictPtr() to get the (potentially negative) dict offset. Don't copy things into local variables that are used only once. type_new(): properly calculate a negative dict offset when tp_itemsize is nonzero. The __dict__ attribute, if present, is now a calculated attribute rather than a structure member.
* Revert the previous patch to test_pow.py and move the test to test_unary.pyFred Drake2001-08-302-10/+8
| | | | | based on a suggestion from Tim Peters; also make sure that we're really doing exponentiation and not multiplication.

* When re-writing a factor containing a unary negation of a literal, onlyFred Drake2001-08-301-0/+3

* More stuff discovered while writing the simplest of testcases:Guido van Rossum2001-08-301-2/+5
| | | | | | | tupledealloc(): only feed the free list when the type is really a tuple, not a subtype. Otherwise, use PyObject_GC_Del(). _PyTuple_Resize(): disallow using this for tuple subtypes.
* Do the int inlining only if the type is really an int, not wheneverGuido van Rossum2001-08-301-6/+9
| | | | | PyInt_Check() succeeds. That returns true for subtypes of int, which may override __add__ or __sub__.

Objects can now have the GC type flag set, reachable by tp_traverse and not be in a GC linked list. This should make the collector more robust and easier to use by extension module writers. Add memory management functions for container objects (new, del, resize).
