From cc32226e647854a02ecd0775787bb08b85e2a014 Mon Sep 17 00:00:00 2001 From: Volker Hilsheimer Date: Tue, 2 Jul 2019 14:28:58 +0200 Subject: Windows: handle errors correctly when connecting to unreachable host MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The previous code handled only some error codes, in a very inefficient way, for some code paths. This change standardizes error handling using a helper function that maps winsock WSAE* codes to Qt error codes. The test for connecting to unreachable hosts or ports is now more generic, and enabled on Windows, where it passes in local tests, but dependency on network configuration still makes it fragile, so ignoring some failures without completely skipping the test.
