3826f2c8ef Refactor endpoint verification prior to connection
Summary:
^

There's a similar issue/request for Android. So, this change moves the code out from the FlipperKit into Flipper as to be able to reuse it.

f1fe66afd9 Use a dispatch queue for websocket operations
Summary:
This diff ensures that all operations on the socket are put into a serial background queue, including delegate callbacks.

All operations are executed asynchronously except disconnect, which is made synchronous as to guarantee no resources are accessed after the call.

30a1d09a83 Dealloc safety improvement
Summary:
From a different diff, it was pointed out that calling methods on self are discouraged:

Generally you want to avoid calling methods on self in dealloc because it allows you to accidentally capture references to self in dealloc, which leads to zombies.

In this case, a disconnect effectively invalidates a timer and disconnect the underlying socket. Both take place either way when the members are deallocated too. The only thing is not done is notify the caller via the event handler of a close event.

In our case, the caller actually manually disconnects before deallocating so this is not an issue.

799d88275e Remove WebSocket delegate before closing
Summary:
This change removes ourselves as a delegate before closing.

SocketRocket uses its own internal async queue to perform most operations.

After a disconnect, we don't expect to receive any more delegate calls as the handlers may contain references which may have become invalid.

So, removing ourselves as delegates will ensure that we don't get called after a disconnect.

For sanity, we are also taking a copy of the message handler instead of a reference to it.

3dacf5a7c9 WebSocket as default socket provider
Summary:
This change makes WebSockets the default for Flipper on iOS.

Having said that, we are introducing some logic to deal with clients connecting to older Flipper Desktop versions.

The mobile client will first attempt to connect via WebSocket with the Desktop. This connection can either be secure or insecure. If that fails, it will attempt to connect via RSocket.

Connection failure logic:
The mobile client will attempt to connect up-to 3 times via a WebSocket. If it fails to connect, then the socket provider is switched to RSocket.

As before, the mobile client will attempt to connect up-to 3 times via a RSocket. If it fails to connect, then the socket provider is switched back to WebSocket.

Process repeats until a successful connection is established.

Some logs that can be seen from iOS:

Summary:

About SocketRocket and Cocoapods

A decision had to be made about whether to define different sub-specs, one for RSocket and another for SocketRocket.

I've opted to keep the podspec as is because:
- Keeps pod consumption as is.
- Makes easier to switch implementations using GK.
- There's no intention to keep RSocket going into the future. So, there's no point in creating a sub-spec only to remove it in the future.
- SocketRocket is a relatively small library so is not contributing to a significant increase in binary size.

If, as reviewer, you consider a subspec makes more sense, then feel free to reach out to discuss.
