There's no reason to stop Emacs 27.2 because of this. Running 8 tests (2021-03-19 11:06:22+0100, selector `(not (or (tag :expensive-test) (tag :unstable)))') Library: `gfilenotify' Monitor: `GFamDirectoryMonitor' Wow! I know that the GFamDirectoryMonitor exists (it is in the gio sources), but I couldn't test it ever. Solaris. Could you pls apply the appended patch to filenotify-tests.el and show the changed filenotify-tests.log file? Many thanks in advance (and be prepared, I will exploit you iteratively until all tests pass. If you agree :-) > Best regards > > — Dago Best regards, Michael.
