annotate Tools/scripts/combinerefs.py @ 87690:66c1c9f32567 default tip

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add use_weakref option to functools.lru_cache The use_weakref option makes lru_cache create weak references to the function arguments when creating the cache key, which prevents them from staying in the memory forever even after all other references to them are gone. This is a proof of concept for http://bugs.python.org/issue19859
