Rev	Summary	Authors	Date
4287.1.11	Small tweaks from Ian. Small tweaks from Ian.	John Arbash Meinel	15 years ago
4287.1.10	Restore the ability to handle None as a key. Restore the ability to handle None as a key. We now use _null_key instead of None to indicate the end-of-refs. This means we now check that _null_key isn't used as an actual key. This slows us down from 7.1 => 7.3s or so. Interestingly, the globals lookup of _null_key was faster than node is self._lru (7.5s+). I was a bit surprised at that.	John Arbash Meinel	15 years ago
4287.1.9	Merge bzr.dev, resolve lru_cache.py Merge bzr.dev, resolve lru_cache.py	John Arbash Meinel	15 years ago
4287.1.8	Because we now store 'key' references, and we use None there... Because we now store 'key' references, and we use None there to indicate the end-of-chain, we can no longer safely map the None object to real values.	John Arbash Meinel	15 years ago
4287.1.7	Fairly significant savings... avoid looking at self._last_re... Fairly significant savings... avoid looking at self._last_recently_used. We can get the same information from node.next_key, which is a value we need anyway. Somewhat surprisingly, this drops us from 7.6s => 7.1s on 2.8M lookups.	John Arbash Meinel	15 years ago
4287.1.6	Remove the double getattr() for self._cache. Remove the double getattr() for self._cache. The common case is that prev and next both exist, so tweak for that case.	John Arbash Meinel	15 years ago
4287.1.5	Switch to using prev as the object and next_key as the point... Switch to using prev as the object and next_key as the pointer. This shouldn't really change the __getitem__ time, but it should make removing the lru a tiny bit more straightforward.	John Arbash Meinel	15 years ago
4287.1.4	use indirection on both next and prev. use indirection on both next and prev. This was done because I thought we still had a cycle. It turns out that we actually just had a frame referencing my cache object, which caused 'del cache' to not actually destroy it.	John Arbash Meinel	15 years ago
4287.1.3	(temporary) Revert back to double-linked list, just with the... (temporary) Revert back to double-linked list, just with the fix for actually removing nodes properly.	John Arbash Meinel	15 years ago
4287.1.2	Properly remove the nodes from the internal linked list in Properly remove the nodes from the internal linked list in _remove_node.	John Arbash Meinel	15 years ago
4287.1.1	Remove the refcycle for _LRUNode. Remove the refcycle for _LRUNode. We access the 'next' node via a direct pointer, but we access the prev node via the dict. Accessing it directly should be faster than accessing via an indirection, but doing it this way means that we can have LRUNode's clean themselves up automatically when you remove the reference to the cache itself, rather than needing an explicit cleanup.	John Arbash Meinel	15 years ago
