Raymond Hettinger 15ce0bee97 Conceptually, roots is a set. Also searching it as a set is a tiny bit faster (#3338) 2017-09-05 09:40:44 -07:00
Raymond Hettinger 550370957c Add comment to explain the implications of not sorting keywords (#3331) 
In Python 3.6, sorted() was removed from _make_key() for the lru_cache and instead rely on guaranteed keyword argument order preservation.  This makes keyword argument handling faster but it also causes multiple callers with a different keyword argument order to be cached as separate items.  Depending on your point of view, this is either a performance regression (increased number of cache misses) or a performance enhancement (faster computation of keys).

Nick Coghlan 457fc9a69e Issue #27137: align Python & C implementations of functools.partial 
The pure Python fallback implementation of functools.partial
now matches the behaviour of its accelerated C counterpart for
subclassing, pickling and text representation purposes.

Raymond Hettinger f2c17a9276 Fix other re-entrancy nits for the lru_cache. 
Keep references for oldkey and oldvalue so they can't
trigger a __del__ method to reenter our thread.

Move the cache[key]=link step to the end, after the link
data is in a consistent state.

Under exotic circumstances, the cache[key]=link step could
trigger reentrancy (i.e. the key would have to have a hash
exactly equal to that for another key in the cache and the
key would need a __eq__ method that makes a reentrant call
our cached function).
