Raymond Hettinger 691d80532b Make sets and deques weak referencable. 2004-05-30 07:26:47 +00:00
Raymond Hettinger 3fd500b4a5 The copy module now handles sets directly. The __copy__ methods are no 
longer needed.
 2004-03-08 18:31:10 +00:00
Raymond Hettinger a3b11e7fb3 * Simplify and speedup logic for tp_print. 
* Speed-up intersection whenever PyDict_Next can be used.
 2003-12-31 14:08:58 +00:00
Raymond Hettinger 81ad32e435 Speedup set.update by using the override mode for PyDict_Merge(). 2003-12-15 21:16:06 +00:00
Raymond Hettinger fb4e33a8e2 Improve algorithm for set.difference when the input is not a set. 2003-12-15 13:23:55 +00:00
Raymond Hettinger 438e02dfc8 * Refactor set.__contains__() 
* Use Py_RETURN_NONE everywhere.
* Fix-up the firstpass check for the tp_print slot.
 2003-12-13 19:38:47 +00:00
Raymond Hettinger 0deab62704 Refactor set.discard() and set.remove(). 2003-12-13 18:53:18 +00:00
Raymond Hettinger dc5ae11abf Use dictionary specific looping idiom where possible. 
Simplifies and speeds-up the code.
 2003-12-13 14:46:46 +00:00
Raymond Hettinger 8f5cdaa784 * Added a new method flag, METH_COEXIST. 
* Used the flag to optimize set.__contains__(), dict.__contains__(),
  dict.__getitem__(), and list.__getitem__().
 2003-12-13 11:26:12 +00:00
Raymond Hettinger bc0f2ab9bb 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.
 2003-11-25 21:12:14 +00:00
Raymond Hettinger a38123e2fa Factor out more duplicate code. 2003-11-24 22:18:49 +00:00
Guido van Rossum 5f4e45d66f 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).
 2003-11-24 04:13:13 +00:00
Raymond Hettinger f5f41bf087 * 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).
 2003-11-24 02:57:33 +00:00
Raymond Hettinger 49ba4c39c4 * 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.
 2003-11-23 02:49:05 +00:00
Raymond Hettinger bfd334a42d Extend temporary hashability to remove() and discard(). 
Brings the functionality back in line with sets.py.
 2003-11-22 03:55:23 +00:00
Raymond Hettinger 19c2d77842 Allow temporary hashability for the __contains__ test. 
(Requested by Alex Martelli.)
 2003-11-21 18:36:54 +00:00
Raymond Hettinger 3fbec701ca issubset() and issuperset() to work with general iterables 2003-11-21 07:56:36 +00:00
Raymond Hettinger 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.

Guido van Rossum b61982bacb Implement straightforward suggestions from gcc warnings (remove unused 
variable, add extra braces).
 2003-11-18 19:27:19 +00:00
Raymond Hettinger 1b92fd5bca Use PySequence_Contains() instead of direct access macro. 2003-11-18 14:15:31 +00:00
Raymond Hettinger 50a4bb325c Various fixups (most suggested by Armin Rigo). 2003-11-17 16:42:33 +00:00
Raymond Hettinger e2c277a69f Fix output spacing typo 2003-11-16 16:36:58 +00:00
Raymond Hettinger a690a9967e * 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.
