Tim Peters 6902b44406 Try to repair more new buildbot failures in "x86 OpenBSD trunk", due
to that id() can now return a Python long on a 32-bit box that allocates
addresses "with the sign bit set".

test_set.py test_subclass_with_custom_hash():  it's never been portably
legal for a __hash__() method to return id(self), but on 32-bit boxes
that never caused a problem before it became possible for id() to
return a Python long.  Changed __hash__ here to return a Python int
regardless of platform.

test_descr.py specials():
    vereq(hash(c1), id(c1))
has never been a correct test -- just removed it (hash() is always
a Python int; id() may be a Python long).

Barry Warsaw 176014ffad SF patch #1458476 with modifications based on discussions in python-dev. This
adds the following API calls: PySet_Clear(), _PySet_Next(), and
_PySet_Update().  The latter two are considered non-public.  Tests and
documentation (for the public API) are included.

Neal Norwitz fcf4435ae0 Improve test coverage. Hope the test_file changes work the same on windows. 2005-11-27 20:37:43 +00:00
Raymond Hettinger 9bda1d6f64 No longer ignore exceptions raised by comparisons during key lookup.
Inspired by Armin Rigo's suggestion to do the same with dictionaries.

Raymond Hettinger c47e01d020 Numerous fix-ups to C API and docs. Added tests for C API. 2005-08-16 10:44:15 +00:00
Raymond Hettinger 97979ddc14 * Fix SF #1257731. Make __contains__(), remove(), and discard() only do
a frozenset conversion when the initial search attempt fails with a
  TypeError and the key is some type of set.  Add a testcase.

* Eliminate a duplicate if-stmt.

Raymond Hettinger c991db240c * Add short-circuit code for in-place operations with self (such as
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.

Raymond Hettinger d794666048 * Improve code for the empty frozenset singleton:
- Handle both frozenset() and frozenset([]).
  - Do not use singleton for frozenset subclasses.
  - Finalize the singleton.
  - Add test cases.
* Factor-out set_update_internal() from set_update().  Simplifies the
  code for several internal callers.
* Factor constant expressions out of loop in set_merge_internal().
* Minor comment touch-ups.

function.

* Add a better test for deepcopying.

* Beefed-up some existing tests.

Includes the docs for libfuncs.tex.  Separate docs for the types are
forthcoming.
