Felix Lange	53a18d2e27	event: document select case slice use and add edge case test (#16680) ... Feed keeps active subscription channels in a slice called 'f.sendCases'. The Send method tracks the active cases in a local variable 'cases' whose value is f.sendCases initially. 'cases' shrinks to a shorter prefix of f.sendCases every time a send succeeds, moving the successful case out of range of the active case list. This can be confusing because the two slices share a backing array. Add more comments to document what is going on. Also add a test for removing a case that is in 'f.sentCases' but not 'cases'.	2018-05-10 13:26:36 +03:00
Felix Lange	1bed9b3fea	event: address review issues (multiple commits) ... event: address Feed review issues event: clarify role of NewSubscription function event: more Feed review fixes * take sendLock after dropping f.mu * add constant for number of special cases event: fix subscribing/unsubscribing while Send is blocked	2017-02-03 13:37:49 +02:00
Felix Lange	6d5e100d0d	event: add new Subscription type and related utilities ... This commit introduces a new Subscription type, which is synonymous with ethereum.Subscription. It also adds a couple of utilities that make working with Subscriptions easier. The mot complex utility is Feed, a synchronisation device that implements broadcast subscriptions. Feed is slightly faster than TypeMux and will replace uses of TypeMux across the go-ethereum codebase in the future.	2017-01-25 18:44:20 +01:00
