The copy module now handles sets directly. The __copy__ methods are no
...
longer needed.

Use dictionary specific looping idiom where possible.
...
Simplifies and speeds-up the code.

* Added a new method flag, METH_COEXIST.
...
* Used the flag to optimize set.__contains__(), dict.__contains__(),
dict.__getitem__(), and list.__getitem__().

Expose dict_contains() and PyDict_Contains() with is about 10% faster
...
than PySequence_Contains() and more clearly applicable to dicts.
Apply the new function in setobject.c where __contains__ checking is
ubiquitous.

Stop GCC warning about int literal that's so long that it becomes an
...
unsigned int (on a 32-bit machine), by adding an explicit 'u' to the
literal (a prime used to improve the hash function for frozenset).

* Checkin remaining documentation
...
* Add more tests
* Refactor and neaten the code a bit.
* Rename union_update() to update().
* Improve the algorithms (making them a closer to sets.py).

* Simplify hash function and add test to show effectiveness of the hash
...
function.
* Add a better test for deepcopying.
* Add tests to show the __init__() function works like it does for list
and tuple. Add related test.
* Have shallow copies of frozensets return self. Add related test.
* Have frozenset(f) return f if f is already a frozenset. Add related test.
* Beefed-up some existing tests.

Extend temporary hashability to remove() and discard().
...
Brings the functionality back in line with sets.py.
2003-11-22 03:55:23 +00:00
19c2d77842
Allow temporary hashability for the __contains__ test.
...
(Requested by Alex Martelli.)

issubset() and issuperset() to work with general iterables
2003-11-21 07:56:36 +00:00
82d73dd459
Three minor performance improvements:
...
* Improve the hash function to increase the chance that distinct sets will
have distinct xor'd hash totals.
* Use PyDict_Merge where possible (it is faster than an equivalent iter/set
pair).
* Don't rebuild dictionaries where the input already has one.

Implement straightforward suggestions from gcc warnings (remove unused
...
variable, add extra braces).

* Migrate set() and frozenset() from the sandbox.
...
* Install the unittests, docs, newsitem, include file, and makefile update.
* Exercise the new functions whereever sets.py was being used.
Includes the docs for libfuncs.tex. Separate docs for the types are
forthcoming.
