Re: [Vala] multithreading -> weird behaviour on win(msys) and macOS

[Wolfgang Mauer <wolfgang mauer kabelmail de>]

Tried this, run perfect on linux, runs "better" on win

                try

                {
                    var mainloop = new MainLoop();
                    SourceFunc quit = ()=>
                    {
                        mainloop.quit ();
                        return Source.REMOVE;
                    };
                    read_piped_commands.begin(spawn_args, quit, 
projectName);
                    mainloop.run();
                }
                catch (SpawnError e)
                {
                    print ("Error: %s\n", e.message);
                }
            }
        }

        async void read_piped_commands(string[] spawn_args, SourceFunc 
quit, string projectName)
        {
            var subprocess = new Subprocess.newv(spawn_args, 
(SubprocessFlags.STDOUT_PIPE|SubprocessFlags.STDERR_MERGE));
            var output = new DataInputStream 
(subprocess.get_stdout_pipe());
            try
            {
                string? line = null;
                do
                {
                    line = yield output.read_line_async ();
                    if (line != null)
                    {
buildTextView.buffer.insert_at_cursor(line+"\n", -1);
                        var mark = buildTextView.buffer.get_insert();
                        buildTextView.scroll_to_mark(mark, 0, true, 1, 1);
                        statusList.AddOutput(projectName, line);
                    }
                }while (line != null);
            }
            catch (Error error)
            {
                print (@"Error: $(error.message)\n");
            }
            quit ();
        }


But on win it looks like the error still goes to terminal and still 
looks weird :-(

No stderr in "buildTextView.buffer", stdout are ok
