| | | | | | | | * 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).

| | | | input (not just tuples).
* #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE and ↵Christian Heimes2007-12-191-26/+26
| | | | Py_REFCNT. Macros for b/w compatibility are available.
* itertools.count() no longer limited to sys.maxint.Raymond Hettinger2007-10-041-9/+70
|
* PEP 3123: Provide forward compatibility with Python 3.0, while keepingMartin v. Löwis2007-07-211-60/+43
| | | | | backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and PyVarObject_HEAD_INIT.
* Fix problems in x64 build that were discovered by the testsuite:Kristján Valur Jónsson2007-05-031-2/+2
| | | | | | | | | | | | - 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.

* Bug #1550714: fix SystemError from itertools.tee on negative value for n.Neal Norwitz2006-09-021-2/+6

* nextlink can be NULL if teedataobject_new fails, so use XINCREF.Neal Norwitz2006-07-231-2/+8
| | | | | | Ensure that dataobj is never NULL. Reported by Klocwork #102
* Fix compiler warning (and whitespace) on Mac OS 10.4. (A lot of this code ↵Neal Norwitz2006-05-271-4/+4

* Add missing PyObject_GC_Track call, causing *some* itertools.tee objects toThomas Wouters2006-04-151-0/+1
| | | | | | | | | 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.
* Make itertools.tee and its internal teedataobject participate in GC. ThisThomas Wouters2006-03-271-19/+71
| | | | | alone does not solve the leak in test_generators, unfortunately, but it is part of test_generators' problem and it does solve other cycles.

* Check return result from Py_InitModule*(). This API can fail.Neal Norwitz2006-01-191-0/+2
| | | | Probably should be backported.
* Add const to several API functions that take char *.Jeremy Hylton2005-12-101-1/+1
| | | | | | | | | | | | | | | | | | | In C++, it's an error to pass a string literal to a char* function without a const_cast(). Rather than require every C++ extension module to put a cast around string literals, fix the API to state the const-ness. I focused on parts of the API where people usually pass literals: PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type slots, etc. Predictably, there were a large set of functions that needed to be fixed as a result of these changes. The most pervasive change was to make the keyword args list passed to PyArg_ParseTupleAndKewords() to be a const char *kwlist[]. One cast was required as a result of the changes: A type object mallocs the memory for its tp_doc slot and later frees it. PyTypeObject says that tp_doc is const char *; but if the type was created by type_new(), we know it is safe to cast to char *.
