gary rong	f78ffc0545	les: create utilities as common package (#20509 ) * les: move execqueue into utilities package execqueue is a util for executing queued functions in a serial order which is used by both les server and les client. Move it to common package. * les: move randselect to utilities package weighted_random_selector is a helpful tool for randomly select items maintained in a set but based on the item weight. It's used anywhere is LES package, mainly by les client but will be used in les server with very high chance. So move it into a common package as the second step for les separation. * les: rename to utils	5 years ago

Felix Lange	e20158176d	les: fix goroutine leak in execQueue (#14480 ) execQueue used an atomic counter to track whether the queue had been closed, but the checking the counter didn't happen because the queue was blocked on its channel. Fix it by using a condition variable instead of sync/atomic. I tried an implementation based on channels first, but it was hard to make it reliable. quit now waits for the queue loop to exit.	7 years ago
