* SF bug #1121416: zip incorrectly and incompletely documentedRaymond Hettinger2005-08-211-4/+4

* SF bug #1249837: container methods raise KeyError not IndexErrorRaymond Hettinger2005-08-211-0/+2
| | | | Minor clarification.
* SF bug #1242657: list(obj) can swallow KeyboardInterruptRaymond Hettinger2005-08-214-0/+31
| | | | | | Fix over-aggressive PyErr_Clear(). The same code fragment appears in various guises in list.extend(), map(), filter(), zip(), and internally in PySequence_Tuple().

* Results of a line-by-line comparison back to dictobject.c.Raymond Hettinger2005-08-171-127/+121
| | | | | | | | | | | | * set_merge() cannot assume that the table doesn't resize during iteration. * convert some unnecessary tests to asserts -- they were necessary in dictobject.c because PyDict_Next() is a public function. The same is not true for set_next(). * re-arrange the order of functions to more closely match the order in dictobject.c. This makes it must easier to compare the two and ought to simplify any issues of maintaining both.
* Numerous fix-ups to C API and docs. Added tests for C API.Raymond Hettinger2005-08-164-26/+148

* * Bring lookkey() and lookkey_string() closer to dict version.Raymond Hettinger2005-08-131-93/+77
| | | | | * Use set_next() for looping in issubset() and frozenset_hash(). * Re-order the presentation of cmp and hash functions.
* Fix a too-aggressive assert (see SF#1257960). Previously, gen_iternextPhillip J. Eby2005-08-131-1/+1
| | | | | | | | | was never called during interpreter shutdown GC, so the f_back!=NULL assertion was correct. Now that generators get close()d during GC, the assertion was being triggered because the generator close() was being called as the top-level frame. However, nothing actually is broken by this; it's just that the condition was unexpected in previous Python versions.
* Teach the sets module to correctly compute s-=s and s^=s as the empty set.Raymond Hettinger2005-08-132-0/+17

| | | | | | | | | | | | | | | | | | | | | s|=s, s&=s, s-=s, or s^=s). Add related tests. * Improve names for several variables and functions. * Provide alternate table access functions (next, contains, add, and discard) that work with an entry argument instead of just a key. This improves set-vs-set operations because we already have a hash value for each key and can avoid unnecessary calls to PyObject_Hash(). Provides a 5% to 20% speed-up for quick hashing elements like strings and integers. Provides much more substantial improvements for slow hashing elements like tuples or objects defining a custom __hash__() function. * Have difference operations resize() when 1/5 of the elements are dummies. Formerly, it was 1/6. The new ratio triggers less frequently and only in cases that it can resize quicker and with greater benefit. The right answer is probably either 1/4, 1/5, or 1/6. Picked the middle value for an even trade-off between resize time and the space/time costs of dummy entries.

| | | | | | | | | | * Give set_lookkey_string() a fast alternate path when no dummy entries are present. * Have set_swap_bodies() reset the hash field to -1 whenever either of bodies is not a frozenset. Maintains the invariant of regular sets always having -1 in the hash field; otherwise, any mutation would make the hash value invalid. * Use an entry pointer to simplify the code in frozenset_hash().
