a) because getdomainname() is not POSIX compliant b) because it invokes NIS and not DNS, thus the desired check can fail. See discussion on https://bugs.kde.org/show_bug.cgi?id=256258 and patch provided there. Reproducible: Always

Git commit cbb7f5750fe2a3b4916a00a648efe71f51af3b77 by Martin Gräßlin. Committed on 07/01/2013 at 08:07. Pushed by graesslin into branch 'master'. Improved resolving whether a window is on local machine Most windows use the hostname in WM_CLIENT_MACHINE, but there are windows using the FQDN (for example libreoffice). So instead of "foo" it is "foo.local.net" or similar. The logic so far has been unable to properly determine whether windows with FQDN are on the local system. In order to solve this problem the handling is split out into an own class which stores the information of hostname and whether it is a local machine. This is to not query multiple times. To determine whether the Client is on the local system getaddrinfo is used for the own hostname and the FQDN provided in WM_CLIENT_MACHINE. If one of the queried names matches, we know that it is on the local machine. The old logic to compare the hostname is still used and getaddrinfo is only a fallback in case hostname does not match. The problem with getaddrinfo is, that it accesses the network and by that could block. To circumvent this problem the calls are moved into threads by using QtConcurrent::run. Obviously this brings disadvantages. When trying to resolve whether a Client is on the local machine and a FQDN is used, the information is initially wrong. The new ClientMachine class emits a signal when the information that the system is local becomes available, but for some things this is just too late: * window rules are already gathered * Session Management has already taken place In both cases this is an acceptable loss. For window rules it just needs a proper matching of the machine in case of localhost (remote hosts are not affected). And the case of session management is very academic as it is unlikely that a restoring session contains remote windows.
