Semver Patch release

• Fix: Identifier not used in Abort init (#1923 @mikkelu)
• Use FoundationNetworking on Linux for Swift 5.1 (#2028 @joscdk)

• Fixes a bug preventing --port, --host, and --bind overrides from being passed to the HTTP server. (#2043)

Notes: Prior to this fix, the console output would display the correct hostname and port, but the server would still bind to default hostname and port.

• Updates to ConsoleKit 4.0.0 Alpha 2 (#2042)

Notes: This updated ConsoleKit release includes property wrapper support and internal cleanup. Vapor's ServeCommand, BootCommand, RouteCommand, and --env and --log flags have been updated to use the new syntax.

• Request no longer requires a Channel to init. Now, it requires an EventLoop and SocketAddress?. (#2037)

Note: This makes testing a Request easier since you can pass in either EmbeddedEventLoop or a real event loop from a group used elsewhere in your tests. Prior to this change, you were required to use EmbeddedChannel and EmbeddedEventLoop both of which are incompatible with real event loops.

• Fixed a data race accessing Application.running. (#2027, #2037)

Note: Application.running allows you to programmatically shutdown your HTTP server from anywhere that you can access Application. This includes routes, commands, etc. Because this can be accessed from any thread, it required synchronization (NSLock) to access.

• XCTApplication test helpers now require explicit start / shutdown. (#2037)

Note: Although a bit more verbose, explicitly starting and shutting down test helpers gives the user more options for how they test their application. It also cuts down on edge cases in the testing implementation.

Example from Vapor's tests with explicit start / shutdown:

let app = Application.create(routes: { r, c in
    r.get("hello", ":a") { req in
        return req.parameters.get("a") ?? ""
    }

    r.get("hello", ":a", ":b") { req in
        return [req.parameters.get("a") ?? "", req.parameters.get("b") ?? ""]
    }
})
defer { app.shutdown() }

let server = try app.testable().start()
defer { server.shutdown() }

try server.test(.GET, "/hello/vapor") { res in
    XCTAssertEqual(res.status, .ok)
    XCTAssertContains(res.body.string, "vapor")
}.test(.POST, "/hello/vapor") { res in
    XCTAssertEqual(res.status, .notFound)
}.test(.GET, "/hello/vapor/development") { res in
    XCTAssertEqual(res.status, .ok)
    XCTAssertEqual(res.body.string, #"["vapor","development"]"#)
}

• Fixed an issue causing Request.query.get / Request.query.subscript to crash. (#2018)

Fixed:

• Fixed a compile time error due to changes in AsyncHTTPClient alpha 2.
