John Plevyak commented on TS-158:
---------------------------------
312 is
return (dir_tag(e) == DIR_MASK_TAG(key->word(2)));
both of which should be unsigned:
#define dir_tag(_e) ((_e)->w[2]&((1<<DIR_TAG_WIDTH)-1))
where inku16 w[5];
and MD5 word returns inku32
and
#define DIR_MASK_TAG(_t) ((_t) & ((1 << DIR_TAG_WIDTH) - 1))
???
> cache should not hold parititon lock over callbacks/review locking

> Project: Traffic Server
> Issue Type: Improvement
> Components: Cache
> Reporter: John Plevyak
> Assignee: John Plevyak
> Fix For: 2.1.0
>
>
> Because we now have far fewer partitions it would be best
> not to hold the partition lock over callbacks to reduce contention
> on this lock and enable better scaling.
> This is a good opportunity to review the locking in the cache as
> well.
