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).

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

6819210b9e PEP 3123: Provide forward compatibility with Python 3.0, while keeping
backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
PyVarObject_HEAD_INIT.

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.

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

9029b5f289 nextlink can be NULL if teedataobject_new fails, so use XINCREF.
Ensure that dataobj is never NULL.

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

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.

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.

1ac754fa10 Check return result from Py_InitModule*(). This API can fail.
Probably should be backported.
