This modifies the websocket notification manager to make use of the newer pattern that synchronizes the
Run
context
with an internalquit
channel to ensure that any exported functions that communicate with the goroutines can't possibly hang during shutdown.This was previously done by storing the
context
in the struct (which is generally discouraged) and protecting it by a mutex which means every single notification had to take the mutex.As can be seen by the diff of this commit, this approach is not only more performant, it's also less code.
