support for the last_is_sticky flag. A few hard to find bugs may be fixed by this patch since the old code was buggy.

This patch modifies the type structures of objects that participate in GC. The object's tp_basicsize is increased when GC is enabled. GC information is prefixed to the object to maintain binary compatibility. GC objects also define the tp_flag Py_TPFLAGS_GC.

This patch adds the type methods traverse and clear necessary for GC implementation.

The error message refers to "append", yet the operation in question is "concat".

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.

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.)

_PyTuple_Resize(). In addition, a change suggested by Jeremy Hylton to limit the size of the free lists is also merged into this patch. Charles wrote initially: """ Test Case: run the following code: class Nothing: def __len__(self): return 5 def __getitem__(self, i): if i < 3: return i else: raise IndexError, i def g(a,*b,**c): return for x in xrange(1000000): g(*Nothing()) and watch Python's memory use go up and up. Diagnosis: The analysis begins with the call to PySequence_Tuple at line 1641 in ceval.c - the argument to g is seen to be a sequence but not a tuple, so it needs to be converted from an abstract sequence to a concrete tuple. PySequence_Tuple starts off by creating a new tuple of length 5 (line 1122 in abstract.c). Then at line 1149, since only 3 elements were assigned, _PyTuple_Resize is called to make the 5-tuple into a 3-tuple. When we're all done the 3-tuple is decrefed, but rather than being freed it is placed on the free_tuples cache. The basic problem is that the 3-tuples are being added to the cache but never picked up again, since _PyTuple_Resize doesn't make use of the free_tuples cache. If you are resizing a 5-tuple to a 3-tuple and there is already a 3-tuple in free_tuples[3], instead of using this tuple, _PyTuple_Resize will realloc the 5-tuple to a 3-tuple. It would more efficient to use the existing 3-tuple and cache the 5-tuple. By making _PyTuple_Resize aware of the free_tuples (just as PyTuple_New), we not only save a few calls to realloc, but also prevent this misbehavior whereby tuples are being added to the free_tuples list but never properly "recycled". """ And later: """ This patch replaces my submission of Sun, 16 Apr and addresses Jeremy Hylton's suggestions that we also limit the size of the free tuple list. I chose 2000 as the maximum number of tuples of any particular size to save. There was also a problem with the previous version of this patch causing a core dump if Python was built with Py_TRACE_REFS. This is fixed in the below version of the patch, which uses tupledealloc instead of _Py_Dealloc. """

Added wrapping macros to dictobject.c, listobject.c, tupleobject.c, frameobject.c, traceback.c that safely prevends core dumps on stack overflow. Macros and functions in object.c, object.h. The method is an "elevator destructor" that turns cascading deletes into tail recursive behavior when some limit is hit.

shared. The default is to save references to the integers in the range -1..99. The lower limit can be set by defining NSMALLNEGINTS (absolute value of smallest integer to be saved) and NSMALLPOSINTS (1 more than the largest integer to be saved). tupleobject.c: Save a reference to the empty tuple to be returned whenever a tuple of size 0 is requested. Tuples of size 1 upto, but not including, MAXSAVESIZE (default 20) are put in free lists when deallocated. When MAXSAVESIZE equals 1, only share references to the empty tuple, when MAXSAVESIZE equals 0, don't include the code at all and revert to the old behavior. object.c: Print some more statistics when COUNT_ALLOCS is defined.

image objects, and lots of new methods. * Added counting of allocations and deallocations of builtin types if COUNT_ALLOCS is defined. Had to move calls to NEWREF down in some files. * Bug fix in sorting lists.
