Prior to this commit, gateways can send 120 events before being
throttled at a terribly slow rate of 1 send per minute.
This commit permits gateways to send 5 events before being throttled at
a rate of slightly less than 120 events per minute.
This reverts commit 660d9893e1.
The commit introduces regular incorrect reconnections. It will be
tracked in another branch and re-merged later once fixed.
This commit refactors a lot of voice's internals to be more stable and
handle more edge cases from Discord's voice servers. It should result in
an overall more stable voice connection.
A few helper functions have been added into voice.Session. Some fields
will have been broken and changed to accomodate for the refactor, as
well.
Below are some commits that have been squashed in:
voice: Fix Speaking() panic on closed
voice: StopSpeaking should not error out
The rationale is added as a comment into the Speaking() method.
voice: Add TestKickedOut
voice: Fix region change disconnecting
This commit makes it so that all API wrapper methods under state will
ignore errors returned from the cabinet setters. This is because an
intermittent error from the state shouldn't shadow the actual result
from the Discord API.
This commit refactors the whole package gateway as well as utils/ws
(formerly utils/wsutil) and voice/voicegateway. The new refactor
utilizes a design pattern involving a concurrent loop and an arriving
event channel.
An additional change was made to the way gateway events are typed.
Before, pretty much any type will satisfy a gateway event type, since
the actual type was just interface{}. The new refactor defines a
concrete interface that events can implement:
type Event interface {
Op() OpCode
EventType() EventType
}
Using this interface, the user can easily add custom gateway events
independently of the library without relying on string maps. This adds a
lot of type safety into the library and makes type-switching on Event
types much more reasonable.
Gateway error callbacks are also almost entirely removed in favor of
custom gateway events. A catch-all can easily be added like this:
s.AddHandler(func(err error) {
log.Println("gateway error:, err")
})
