Motivation:
Previously we would use the combination of DispatchQueue.asyncAfter and
a DispatchWorkItem for the connect timeout. If the connection succeeded
we would just cancel the DispatchWorkItem. Unfortunately that will still
keep everything that's captured in the DispatchWorkItem alive until the
deadline has come (because DispatchWorkItem is just a dumb wrapper over
a closure).
Modifications:
use a DispatchSource of type timer source instead.
Result:
- we won't keep the ELG/EL/Channel/... alive until at least the connect
timeout expires.
- fixes#28
Motivation:
Compiling code is good so let's make it compile again with the latest
NIO APIs.
Modifications:
- made NIOTS use `_NIO1APIShims`
- clicked 'Fix All' a couple of times to adjust the API
Result:
Code compiles again
Motivation:
SwiftPM from Swift 5.0 brings targets that only support certain systems
which is really handy for this package as it only support macOS 10.14+
and iOS/tvOS 12+
Modifications:
- made use of the Swift 5.0 manifests which can have restrictions on the
supported platforms
- adapted to NIO 2
Result:
- better development story
- using the latest & greatest
Motivation:
We were inadvertently modifying the registration information of
NIOTSEventLoop objects from multiple threads, which is very not good.
Modifications:
Add an event loop execute to hop loops.
Result:
Thread safe!
Motivation:
In SwiftNIO 1.11 we shipped improved interfaces for Channels to support
asserting being in the event loop. This is necessary because Dispatch
provides no non-precondition way to 100% guarantee that you are on a
specific queue, which is a requirement for accurate behaviour of
inEventLoop.
Modifications:
- Added an implementation of preconditionInEventLoop.
- Changed all assertions to use new interface.
- Required NIO 1.11.
Result:
Accurate assertions
* Use DispatchWorkItem.cancel() for cancellation. Make StateManagedChannel.beginActivating() use the same methodology as all the others.
* A needless `if let x = opt` that could be replaced with a question mark.
