Barry Warsaw 7ce3694a52 repr's converted to using PyString_FromFormat() instead of sprintf'ing
into a hardcoded char* buffer.

Closes patch #454743.

Thomas Wouters efafcea280 Re-add 'advanced' xrange features, adding DeprecationWarnings as discussed
on python-dev. The features will still vanish, however, just one release
later.

Guido van Rossum 3f56166b1a Rip out the fancy behaviors of xrange that nobody uses: repeat, slice,
contains, tolist(), and the start/stop/step attributes.  This includes
removing the 4th ('repeat') argument to PyRange_New().

Guido van Rossum 65e0b99b61 SF patch #103158 by Greg Ball: Don't do unsafe arithmetic in xrange
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...

Fred Drake 0b796fa5c5 Fixed support for containment test when a negative step is used; this
*really* closes bug #121965.

Added three attributes to the xrange object: start, stop, and step.  These
are the same as for the slice objects.

Fred Drake a91e1650aa In the containment test, get the boundary condition right. ">" was used
where ">=" should have been.

This closes bug #121965.

Guido van Rossum 8586991099 REMOVED all CWI, CNRI and BeOpen copyright markings.
This should match the situation in the 1.6b1 tree.

Tim Peters 72d421b75c Boost buffer sizes in the absence of snprintf on Windows.
Ensure that # of args to sprintf always matches # of format specifiers.
2000-08-04 03:05:40 +00:00
Fred Drake c76e0e5679 snprintf() is not portable, so continue to use sprintf() until a portable
snprintf() is available.

Fred Drake 2b83b4601f Remove the tp_print handler.
Revise the tp_repr handler to produce a more "minimal" presentation.
Make the tolist() method use PyArg_ParseTuple() and provide a docstring.

Fred Drake 56780257c6 Thomas Wouters <thomas@xs4all.net>:
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.

Guido van Rossum b18618dab7 Vladimir Marangozov's long-awaited malloc restructuring.
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.)

Guido van Rossum 03093a248d * Include/classobject.h, Objects/classobject.c, Python/ceval.c:
entirely redone operator overloading.  The rules for class
	instances are now much more relaxed than for other built-in types
	(whose coerce must still return two objects of the same type)

	* Objects/floatobject.c: add overflow check when converting float
	to int and implement truncation towards zero using ceil/float

	* Objects/longobject.c: change ValueError to OverflowError when
	converting to int

	* Objects/rangeobject.c: modernized

	* Objects/stringobject.c: use HAVE_LIMITS instead of __STDC__

	* Objects/xxobject.c: changed to use new style (not finished?)

Guido van Rossum 7d6aa51b56 * rangeobject.[ch], bltinmodule.c: incorporate new version of range
object (unchanged from source except "range" -> "xrange").
1993-12-21 22:50:31 +00:00
Guido van Rossum 2586bf0a34 * rangeobject.{c,h}, bltinmodule.c: removed non-essential ops from range
object.

Guido van Rossum 12d12c5faf * compile.[ch]: support for lambda()
* PROTO.h, mymalloc.h: added #ifdefs for TURBOC and GNUC.
* allobjects.h: added #include "rangeobject.h"
* Grammar: added lambda_input; relaxed syntax for exec.
* bltinmodule.c: added bagof, map, reduce, lambda, xrange.
* tupleobject.[ch]: added resizetuple().
* rangeobject.[ch]: new object type to speed up range operations (not
  convinced this is needed!!!)
