Fred Drake 3bae7ddf8e WeakKeyDictionary.has_key(): If the key being tested is not weakly
referencable (weakref.ref() raises TypeError), return 0 instead of
propogating the TypeError.
This closes SF bug #478536; bugfix candidate.

Fred Drake e029242d5c ReferenceError is now built-in, so pick it up from the right place.
It still needs to be here to preserve the API.

Fred Drake 746fe0fae5 Clean up circular references in the Weak*Dictionary classes; this avoids
depending on the cycle detector code in the library implementation.
This is a *slightly* different patch than SF patch #417795, but takes
the same approach.  (This version avoids calling the __len__() method of
the dict in the remove() functions.)
This closes SF patch #417795.

Fred Drake b663a2ccbd Add __delitem__() support for WeakKeyDictionary.
This closes SF bug #458860.

Fred Drake 4fd06e0170 Make sure that WeakValueDictionary[] raises KeyError instead of TypeError
for keys that are not in the dictionary.

Fred Drake 101209d44c Added iterator support to the Weak*Dictionary classes. 2001-05-02 05:43:09 +00:00
Fred Drake bd7f818c50 Weak*Dictionary: Added docstrings to the classes.
Weak*Dictionary.update():  No longer create a temporary list to hold the
    things that will be stuffed into the underlying dictionary.  This had
    been done so that if any of the objects used as the weakly-held value
    was not weakly-referencable, no updates would take place (TypeError
    would be raised).  With this change, TypeError will still be raised
    but a partial update could occur.  This is more like other .update()
    implementations.

Thoughout, use of the name "ref" as a local variable has been removed.  The
original use of the name occurred when the function to create a weak
reference was called "new"; the overloaded use of the name could be
confusing for someone reading the code.  "ref" used as a variable name
has been replaced with "wr" (for 'weak reference').

Fred Drake 1d9e4b7de3 Weak*Dictionary.update(): Fix calls to [].append() to only have one
parameter.

Weak*Dictionary.get():  Make the second parameter optional.

WeakKeyDictionary.has_key(), .keys():  Make these actually work!

Fred Drake 9a9d219f07 mapping(): Remove this function since it does not add anything to the API. 2001-04-10 19:11:23 +00:00
Skip Montanaro 40fc16059f final round of __all__ lists (I hope) - skipped urllib2 because Moshe may be
giving it a slight facelift

Fred Drake 9d2c85dec7 Change WeakDictionary to WeakValueDictionary in a couple more places.
WeakValueDictionary.copy(),
WeakKeyDictionary.copy():  Actually return the copy!

Fred Drake 0399bd8ce2 Ouch! I need a better test suite for this. ;-( 2001-02-02 19:28:35 +00:00
Fred Drake 312a5dc539 WeakDictionary.items(): Do not allow (key,ref) pairs to leak out for
dead references.
