### Motivation:
To migrate to GitHub actions and centralised infrastructure.
### Modifications:
Changes of note:
* Adopt swift-format using rules from SwiftNIO. Modified so that it
ignores `NoAssignmentInExpressions` in some `XCTAssert` functions.
* Remove scripts and docker files which are no longer needed
### Result:
Feature parity with old CI.
Motivation:
With NIO 2.32.0 we broke the core NIO module up into modules that split
apart the POSIX layer and the core abstractions. As a result, this
package no longer needs to express a hard dependency on the POSIX layer.
Modifications:
- Rewrote imports of NIO to NIOCore.
- Added NIOEmbedded imports where necessary in tests.
- Note that the main package still _depends_ on NIO, which is necessary
for backwards-compatibility reasons. This dependency is unused.
Result:
No need to use NIOPosix.
Motivation:
`NWEndpoint` added a `.url` case for macOS 10.15 which commit afbbead added
support for. However, in doing so it also broke support for 10.14.
Modifications:
Handle `.url` in the `default` case and also remove `@unknown` from the
cases of the switch statements in NIOTSListenerChannel and SocketAddress
init.
Result:
Compiles on 10.14.
Motivation:
macOS Catalina brings a .url endpoint to Network.framework, which is
currently causing build warnings. We should tolerate it and silence
those warnings.
Modifications:
Do the right thing when we receive a .url endpoint.
Result:
No build warnings.
Motivation:
With Network.framework becoming available on watchOS, you should now be
able to run your favourite NIO applications on watchOS 6!
Modifications:
Updated availability annotations to allow NIO TS.
Result:
More NIO on more watches
* Annotate code with availability attributes
Motivation:
It was not possible to import NIOTS into a project where
Network.framework was not supported by all deployment targets.
Modifications:
All NIOTS code, where applicable, was annotated with availability
attributes.
Result:
It is possible for application developers to import NIOTS on platforms
which do not support Network.framework without a compile time error.
Motivation:
At least in some cases it's possible to have a local or remote address
that we cannot represent in a SocketAddress. In the face of that, we were
unnecessarily crashing. Crashes should probably be avoided there.
Modifications:
- Replace the crashes with throws.
Result:
Fewer crashes, more nils.
Motivation:
NIOTS will not work on Linux but we can at least make it not fail
compilation when compiled on Linux. That way consumers of the API can
depend on NIOTS but make sure they only use NIOTS when wrapped in a
`#if canImport(Network)` block.
Modification:
Guard everything by `#if canImport(Network)`
Result:
This package will now build on Linux (without providing any useful
code).
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
