This is a reland of https://dart-review.googlesource.com/c/sdk/+/62484 with the following changes: - _NativeSocket.connect now drops references to pending sockets on an error or successful connection. - eventhandlers are updated to ignore unset Dart ports on a close command. - Test updated to account for new SocketException. This is the second part of https://dart-review.googlesource.com/c/sdk/+/62484 This CL adds a startConnect method to Socket types that returns a ConnectionTask object that can be cancelled. Cancelling a ConnectionTask closes any sockets that were opened for the connection attempt that are not yet connected to the host. This allows a closing HttpClient to close sockets for pending requests whose sockets weren't fully connected yet. related https://github.com/flutter/flutter/issues/18617 Change-Id: I47fe3564e41197d622079aad4bb644bbdfe0bfe8 Reviewed-on: https://dart-review.googlesource.com/63040 Reviewed-by: Zach Anderson <zra@google.com> Commit-Queue: Zach Anderson <zra@google.com>
