I'm wondering if you can still remember the rational behind the cache
code at around lines 355-387 of:
This code is pretty old (checked in 5th Dec 1997) but has started
causing a few people problems under high load:
- in line 368, why is len(cache)>max_cache/2 used as a trigger to start
cache clearing? (the /2 in particular)
- does it matter that IOBTree.Bucket has gone away and that tcache is
now a simple dictionary? It certainly seems to make the keys.reverse()
on line 370 superfluous and the keys[-1]<t on line 371 less reliable.
More generally, do you or does anyone else have any attachment to this
code or would anyone mind if I ripped it out and replaced it with
something simpler, with more comments and unit tests?
