*	SF 1055820: weakref callback vs gc vs threads	Tim Peters	2004-10-30	1	-0/+20
\| \| \| \| \| \| \| \|	In cyclic gc, clear weakrefs to unreachable objects before allowing any Python code (weakref callbacks or __del__ methods) to run. This is a critical bugfix, affecting all versions of Python since weakrefs were introduced. I'll backport to 2.3.
*	Make weak references subclassable:	Fred Drake	2004-07-02	1	-1/+6
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	- weakref.ref and weakref.ReferenceType will become aliases for each other - weakref.ref will be a modern, new-style class with proper __new__ and __init__ methods - weakref.WeakValueDictionary will have a lighter memory footprint, using a new weakref.ref subclass to associate the key with the value, allowing us to have only a single object of overhead for each dictionary entry (currently, there are 3 objects of overhead per entry: a weakref to the value, a weakref to the dictionary, and a function object used as a weakref callback; the weakref to the dictionary could be avoided without this change) - a new macro, PyWeakref_CheckRefExact(), will be added - PyWeakref_CheckRef() will check for subclasses of weakref.ref This closes SF patch #983019.
*	SF bug 839548: Bug in type's GC handling causes segfaults.	Tim Peters	2003-11-20	1	-0/+2
\| \| \| \| \| \| \| \|	Also SF patch 843455. This is a critical bugfix. I'll backport to 2.3 maint, but not beyond that. The bugs this fixes have been there since weakrefs were introduced.
