* Tidied up the implementations of reversed (including the custom onesRaymond Hettinger2004-03-101-1/+13
| | | | | | | | | | | | | | | | | for xrange and list objects). * list.__reversed__ now checks the length of the sequence object before calling PyList_GET_ITEM() because the mutable could have changed length. * all three implementations are now tranparent with respect to length and maintain the invariant len(it) == len(list(it)) even when the underlying sequence mutates. * __builtin__.reversed() now frees the underlying sequence as soon as the iterator is exhausted. * the code paths were rearranged so that the most common paths do not require a jump.

* Renamed PyObject_GenericGetIter to PyObject_SelfIterRaymond Hettinger2003-03-171-1/+1

* Created PyObject_GenericGetIter().Raymond Hettinger2003-03-171-8/+1

* Restore attribute access so that the following work again:Raymond Hettinger2002-11-071-1/+1

* Untested code for 64-bit platforms. range_length() is declared as intGuido van Rossum2002-09-111-1/+8
| | | | | | | | | | but returns r->len which is a long. This doesn't even cause a warning on 32-bit platforms, but can return bogus values on 64-bit platforms (and should cause a compiler warning). Fix this by inserting a range check when LONG_MAX != INT_MAX, and adding an explicit cast to (int) when the test passes. When r->len is out of range, PySequence_Size() and hence len() will report an error (but an iterator will still work).
* staticforward bites the dust.Jeremy Hylton2002-07-171-2/+2
| | | | | | | | | | | | | | | 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.
* Remove the next() method -- one is supplied automatically byGuido van Rossum2002-07-161-10/+1
| | | | | | PyType_Ready() because the tp_iternext slot is set. Also removed the redundant (and expensive!) call to raise StopIteration from rangeiter_next().

| | | | | Also, added more regression tests to cover the new type and test its conformity with range().

* Fix attribute access for the xrange objects. The tp_getattr and tp_getattroFred Drake2002-05-021-31/+38

* SF patch #103158 by Greg Ball: Don't do unsafe arithmetic in xrangeGuido van Rossum2001-01-151-10/+80
| | | | | | | | | | | | | | | object. This fixes potential overflows in xrange()'s internal calculations on 64-bit platforms. The fix is complicated because the sq_length slot function can only return an int; we want to support xrange(sys.maxint), which is a 64-bit quantity on most 64-bit platforms (except Win64). The solution is hacky but the best possible: when the range is that long, we can use it in a for loop but we can't ask for its length (nor can we actually iterate beyond 2**31-1, because the sq_item slot function has the same restrictions on its arguments. Fixing those restrictions is a project for another day...

* Fixed support for containment test when a negative step is used; thisFred Drake2000-11-081-8/+34
| | | | | | | *really* closes bug #121965. Added three attributes to the xrange object: start, stop, and step. These are the same as for the slice objects.
* In the containment test, get the boundary condition right. ">" was usedFred Drake2000-11-081-2/+2

* REMOVED all CWI, CNRI and BeOpen copyright markings.Guido van Rossum2000-09-011-9/+0

* Boost buffer sizes in the absence of snprintf on Windows.Tim Peters2000-08-041-14/+19
| | | | Ensure that # of args to sprintf always matches # of format specifiers.
* snprintf() is not portable, so continue to use sprintf() until a portableFred Drake2000-08-041-8/+6

* Remove the tp_print handler.Fred Drake2000-08-031-31/+27
| | | | | Revise the tp_repr handler to produce a more "minimal" presentation. Make the tolist() method use PyArg_ParseTuple() and provide a docstring.

* Thomas Wouters <thomas@xs4all.net>:Fred Drake2000-06-151-0/+25
| | | | | | | | | | | | | | | The following patch adds "sq_contains" support to rangeobject, and enables the already-written support for sq_contains in listobject and tupleobject. The rangeobject "contains" code should be a bit more efficient than the current default "in" implementation ;-) It might not get used much, but it's not that much to add. listobject.c and tupleobject.c already had code for sq_contains, and the proper struct member was set, but the PyType structure was not extended to include tp_flags, so the object-specific code was not getting called (Go ahead, test it ;-). I also did this for the immutable_list_type in listobject.c, eventhough it is probably never used. Symmetry and all that.
* Vladimir Marangozov's long-awaited malloc restructuring.Guido van Rossum2000-05-031-1/+1
| | | | | | | | | | For more comments, read the patches@python.org archives. For documentation read the comments in mymalloc.h and objimpl.h. (This is not exactly what Vladimir posted to the patches list; I've made a few changes, and Vladimir sent me a fix in private email for a problem that only occurs in debug mode. I'm also holding back on his change to main.c, which seems unnecessary to me.)
