* 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.

* 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.)
