Niko Matsakis	be983aacdf	extract read_upgrade into a separate helper ... And use it from `maybe_changed_since` where it makes sense.	2018-10-15 08:53:52 -04:00
Niko Matsakis	2ba9c97815	rewrite to thread a Vec<Receiver> to signal waiters ... This is both more precise and the logic is simpler.	2018-10-15 08:28:55 -04:00
Niko Matsakis	373e1158f3	only acquire a read-lock when verifying inputs ... We no longer use a placeholder.	2018-10-15 05:32:24 -04:00
Niko Matsakis	04288dadef	track whether a query is in progress more accurately	2018-10-15 05:24:36 -04:00

Niko Matsakis	00c76be635	refactor derived read to only require read lock ... The old setup acquired `upgradable_read` even when the value was cached. At that point you might as well just a mutex.	2018-10-13 05:45:57 -04:00
