Alexandre Vassalotti	1f2f61a78f	Issue 2582: Fix pickling of xrange objects.	18 years ago
Gregory P. Smith	dd96db63f6	This reverts r63675 based on the discussion in this thread: http://mail.python.org/pipermail/python-dev/2008-June/079988.html Python 2.6 should stick with PyString_* in its codebase. The PyBytes_* names in the spirit of 3.0 are available via a #define only. See the email thread.	18 years ago
Christian Heimes	593daf545b	Renamed PyString to PyBytes	18 years ago
Raymond Hettinger	0913166da2	Remove unnecessary modulo division. The preceding test guarantees that 0 <= i < len.	18 years ago
Martin v. Löwis	72d206776d	Remove "static forward" declaration. Move constructors after the type objects.	20 years ago
Thomas Wouters	f4d8f39053	Make xrange more Py_ssize_t aware, by assuming a Py_ssize_t is always at least as big as a long. I believe this to be a safe assumption that is being made in many parts of CPython, but a check could be added. len(xrange(sys.maxint)) works now, so fix the testsuite's odd exception for 64-bit platforms too. It also fixes 'zip(xrange(sys.maxint), it)' as a portable-ish (if expensive) alternative to enumerate(it); since zip() now calls len(), this was breaking on (real) 64-bit platforms. No additional test was added for that behaviour.	20 years ago

Tim Peters	feec4533e2	Bug 1003935: xrange overflows Added XXX comment about why the undocumented PyRange_New() API function is too broken to be worth the considerable pain of repairing. Changed range_new() to stop using PyRange_New(). This fixes a variety of bogus errors. Nothing in the core uses PyRange_New() now. Documented that xrange() is intended to be simple and fast, and that CPython restricts its arguments, and length of its result sequence, to native C longs. Added some tests that failed before the patch, and repaired a test that relied on a bogus OverflowError getting raised.	22 years ago

Michael W. Hudson	f8df9a89bc	Add a missing decref.	22 years ago
Raymond Hettinger	ef9bf4031a	Tidied up the implementations of reversed (including the custom ones 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.	22 years ago

Raymond Hettinger	1da1dbf458	Renamed PyObject_GenericGetIter to PyObject_SelfIter to more accurately describe what the function does. Suggested by Thomas Wouters.	23 years ago
Raymond Hettinger	0153826964	Created PyObject_GenericGetIter(). Factors out the common case of returning self.	23 years ago

Raymond Hettinger	5ae8e01cc5	Restore attribute access so that the following work again: dir(xrange(10)) xrange(10).__getitem__(4)	24 years ago
Guido van Rossum	d4774fb6ef	Untested code for 64-bit platforms. range_length() is declared as int 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).	24 years ago
Jeremy Hylton	938ace69a0	staticforward bites the dust. 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.	24 years ago
Guido van Rossum	86d593e110	Remove the next() method -- one is supplied automatically by PyType_Ready() because the tp_iternext slot is set. Also removed the redundant (and expensive!) call to raise StopIteration from rangeiter_next().	24 years ago

Raymond Hettinger	48165d40cb	SF 564601 adding rangeiterobject to make xrange() iterate like range().	24 years ago

Fred Drake	d9018323c0	Remove old deprecated features from the xrange object.	24 years ago
Fred Drake	edb51bb7e8	Fix attribute access for the xrange objects. The tp_getattr and tp_getattro handlers were both set, but were not compatible. This change uses only the tp_getattro handler with a more "modern" approach. This fixes SF bug #551285.	24 years ago

Guido van Rossum	03b3f04542	long_mul(): The PyNumber_Multiply() call can return a long if the result would overflow an int. Check for this. (SF bug #488482, Armin Rigo.)	24 years ago
Barry Warsaw	7ce3694a52	repr's converted to using PyString_FromFormat() instead of sprintf'ing into a hardcoded char* buffer. Closes patch #454743.	25 years ago

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.	25 years ago
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().	25 years ago
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...	25 years ago
Guido van Rossum	9e8f4ea0aa	Test for NULL returned from PyObject_NEW().	25 years ago
