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")
})
This commit gets rid of contain-it-all structs and instead opt for
interface union types containing underlying concrete types with no
overloading.
The code is much more verbose by doing this, but the API is much nicer
to use. The only disadvantage in that regard is the interface assertion
being too verbose and risky for users at times.
This commit refactors a lot of packages.
It refactors the handler package, removing the Synchronous field and
replacing it the AddSyncHandler API, which allows each handler to
control whether or not it should be ran synchronously independent of
other handlers. This is useful for libraries that need to guarantee the
incoming order of events.
It also refactors the store interfaces to accept more interfaces. This
is to make the API more consistent as well as reducing potential useless
copies. The public-facing state API should still be the same, so this
change will mostly concern users with their own store implementations.
Several miscellaneous functions (such as a few in package gateway) were
modified to be more suitable to other packages, but those functions
should rarely ever be used, anyway.
Several tests are also fixed within this commit, namely fixing state's
intents bug.
* Gateway: Fix Gateway.Open overwriting the context argument
* WSUtil: Remove max context timeout in Websocket.Dial
* WSUtil: Use Websocket.Timeout if a no-deadline context is given to .Dial
* WSUtil: Add doc to Websocket.Timeout clarifying that it must not be changed after use
This change skips events that are unknown while the bot reconnects. This
is an event that is particularly rare as it requires unimplemented
events being called in the time before a bot's HELLO -> RESUME events
are called. This change explicitly returns unknown events as a special
time defined in wsutil/op.go and ignores them from reaching gateway/op.go
api.{Send,Edit}MessageData and their equivalents in package api/webhook
have been updated to add some fields added in Discord API v9.
(webhook.Client).EditMessage now also returns a message, because that
endpoint returns a message on success.
* Gateway: Fix gateway reconnect
This commit uses the correct timeout, Gateway.ReconnectTimeout, when reconnecting. Furthermore, it adds a delay between consecutive, failed reconnects.
* Gateway: Stop pacemaker when calling Gateway.CloseGracefully
* API: remove unnecessary leading/trailing whitespaces
* Gateway: Add Gateway.OnScalingRequired callback
* Gateway: Make all user initiated user closures graceful and ensure that closures are respected during reconnects
* Gateway: Fix typo
* Gateway: Add Gateway.ReconnectAttempts and deprecate .ReconnectTimeout
* Gateway: Add Gateway.Pause and reexport .Reconnect and .ReconnectCtx
* Gateway: Improve the Gateway.OnShardingRequired docs
* Wsutil: Code cleanup
* gateway: add the possibility of graceful closure
* wsutil: rename ConnGracefulCloser to GracefulCloser
* Gateway: rename Gateway.CloseSession to .CloseGracefully
This commit consists of these smaller commits:
Gateway: SessionID to be a method for thread safety
This commit breaks the SessionID field of the Gateway struct to
be thread-safe by wrapping its access with a read-write mutex.
As this is a bug fix, it is reasonable of a breaking change
Heart: Allow later binding of event channel
Voice: Use the new Heart API
Heart: Fixed data races
Heart: Allow changing pace, thread-safe Heartbeat
This commit moved ExecuteWebhookData from package api to package webhook
inside package api. This change required splitting the multipart
abstractions away from package api, so they are now inside package
sendpart in utils.
This commit will break code that uploads anything, as the type name is
now sendpart.File from api.SendMessageFile. The behavior should be the
same as before.
* Rate: don't sleep if sleep exceeds context deadline
* Httputil: add Client.Timeout
* Bot: set default API timeout to 5 minutes
* Rate: reduce calls to time.Now in Acquire
* API: Optimize to use deadline instead of recalculating

This commit refactors both wsutil, the normal Gateway and the Voice
Gateway to have better closing behavior, which should assume less and
cover edge cases completely.
