Raymond Hettinger 80d49b33b1 Issue 7244: fix exception handling in itertools.izip_longest(). 2009-11-01 08:53:21 +00:00
Raymond Hettinger 825758c50b - Issue 4816: itertools.combinations() and itertools.product were raising 
a ValueError for values of *r* larger than the input iterable.  They now
  correctly return an empty iterator.

Georg Brandl 8550d69a84 #2536: fix itertools.permutations and itertools.combinations docstrings. 2008-06-10 12:46:39 +00:00
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.

Christian Heimes cdddf18768 The empty tuple is usually a singleton with a much higher refcnt than 1 2008-02-28 11:18:49 +00:00

Raymond Hettinger 73d7963242 Improve the implementation of itertools.product() 
* Fix-up issues pointed-out by Neal Norwitz.
* Add extensive comments.
* The lz->result variable is now a tuple instead of a list.
* Use fast macro getitem/setitem calls so most code is in-line.
* Re-use the result tuple if available (modify in-place instead of copy).
 2008-02-23 02:20:41 +00:00
Raymond Hettinger 50986cc45b First draft for itertools.product(). Docs and other updates forthcoming. 2008-02-22 03:16:42 +00:00
Raymond Hettinger 473170908e Make starmap() match its pure python definition and accept any itertable input (not just tuples). 2008-01-17 03:02:14 +00:00
Christian Heimes e93237dfcc #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE and Py_REFCNT. Macros for b/w compatibility are available. 2007-12-19 02:37:44 +00:00

Kristján Valur Jónsson f030394de3 Fix problems in x64 build that were discovered by the testsuite: 
- Reenable modules on x64 that had been disabled aeons ago for Itanium.
- Cleared up confusion about compilers for 64 bit windows.  There is only Itanium and x64.  Added macros MS_WINI64 and MS_WINX64 for those rare cases where it matters, such as the disabling of modules above.
- Set target platform (_WIN32_WINNT and WINVER) to 0x0501 (XP) for x64, and 0x0400 (NT 4.0) otherwise, which are the targeted minimum platforms.
- Fixed thread_nt.h.  The emulated InterlockedCompareExchange function didn´t work on x64, probaby due to the lack of a "volatile" specifier.  Anyway, win95 is no longer a target platform.
- Itertools module used wrong constant to check for overflow in count()
- PyInt_AsSsize_t couldn't deal with attribute error when accessing the __long__ member.
- PyLong_FromSsize_t() incorrectly specified that the operand were unsigned.

With these changes, the x64 passes the testsuite, for those modules present.

Georg Brandl b84c13792d Bug #1486663: don't reject keyword arguments for subclasses of builtin 
types.
 2007-01-21 10:28:43 +00:00
Jack Diederich 36234e8f66 * regression bug, count_next was coercing a Py_ssize_t to an unsigned Py_size_t 
which breaks negative counts
* added test for negative numbers
will backport to 2.5.1
 2006-09-21 17:50:26 +00:00
Neal Norwitz 69e8897505 Bug #1550714: fix SystemError from itertools.tee on negative value for n. 
Needs backport to 2.5.1 and earlier.
 2006-09-02 02:58:13 +00:00
Neal Norwitz 9029b5f289 nextlink can be NULL if teedataobject_new fails, so use XINCREF. 
Ensure that dataobj is never NULL.

Reported by Klocwork #102

Neal Norwitz 2f3136b8f0 Fix compiler warning (and whitespace) on Mac OS 10.4. (A lot of this code looked duplicated, I wonder if a utility function could help reduce the duplication here.) 2006-05-27 05:18:57 +00:00
Jack Diederich 6c433a91d5 use Py_ssize_t in places that may need it 2006-05-26 11:15:17 +00:00
Thomas Wouters b3deb94dc6 Add missing PyObject_GC_Track call, causing *some* itertools.tee objects to 
not be tracked by GC. This fixes 254 of test_generators' refleaks on my
machine, but I'm sure something else will make them come back :>

Not adding a separate test for this kind of cycle, since the existing
fib/m235 already test them in more extensive ways than any 'minimal' test
has been able to manage.
 2006-04-15 22:33:13 +00:00
Thomas Wouters 19bf33bc7a Make itertools.tee and its internal teedataobject participate in GC. This 
alone does not solve the leak in test_generators, unfortunately, but it is
part of test_generators' problem and it does solve other cycles.
 2006-03-27 21:02:13 +00:00
Martin v. Löwis 02cbf4ae4b More unconsting. 2006-02-27 17:20:04 +00:00
Martin v. Löwis ad0a4629be Use Py_ssize_t for counts and sizes. 2006-02-16 14:30:23 +00:00
Armin Rigo f5b3e36493 Renamed _length_cue() to __length_hint__(). See: 
http://mail.python.org/pipermail/python-dev/2006-February/060524.html
 2006-02-11 21:32:43 +00:00
Neal Norwitz 1ac754fa10 Check return result from Py_InitModule*(). This API can fail. 
Probably should be backported.
