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'.	7 years ago

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'.

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.
