Duarte Nunes	c053275a48	db/view/row_locking: Add timeout when waiting for the lock ... This ensures we respect the write timeout set by the client when applying base writes, in case a writes takes too long to acquire the row lock for the read-before-write phase of a materialized view update.

Nadav Har'El	52e91623ce	Materialized views: test row_locker class ... This is a unit test for the row_locker facility. It tests various combination of shared and exclusive locks on rows and on partitions, some should succeed immediately and some should block. This tests the row_locker's API only, it does not use or test anything in Materialized Views. Signed-off-by: Nadav Har'El <nyh@scylladb.com>	2018-01-30 16:19:43 +02:00
