Due to the nature of file notification events, those `changed' events could appear from anywhere. As you might imagine, I cannot reproduce the problems locally. Also hydra does not report about. The only exception is `file-notify-test08-watched-file-in-watched-dir-remote', which has failed here as well. The remote `gvfs-monitor-dir' library is a little bit fickle. We have done some work in the master branch, which is not contained in the emacs-25 branch. I don't see any problem running the tests in the master branch. Do you see the problems also in the master branch? It might be also interesting to know whether the failed tests appear also during an ordinary "make check". I suppose you have applied "make -C test/automated file-notify-tests", which runs the expensive tests. > PS as you can see from the log, these tests took ~ 15 minutes to run. Yes. The expensive tests contain tests with a looooot of events, because some of the problems have appeared only in stress situations. On my 6-years-old laptop, running Ubuntu 16.04, the tests take ~12 minutes. Best regards, Michael. ^ permalink raw reply [flat|nested] 9+ messages in thread

Current master make check: 3 unexpected results: FAILED file-notify-test02-events FAILED file-notify-test04-file-validity FAILED file-notify-test07-backup Still due to extra "changed" events. ^ permalink raw reply [flat|nested] 9+ messages in thread

OK, I'll try to get an RHEL 7.2 VM in order to reproduce it. Or maybe a CentOS VM, in case RHEL VMs are not available. In case it fails, I will send you an instrumentation patch for filenotify-tests.el. We do agree that we work on the master branch, don't we?

I haven't been able to reproduce the problems this way :-( Anyway, the bug in `file-notify-test08-watched-file-in-watched-dir-remote' I could fix (this was the only one I could reproduce locally). Furthermore, I've added code to filenotify-tests.el in order to make it more robust. That' means especially, that no events could arrive during a test, resulting from a *previous* test. Maybe this fixes the other problems already. Committed to the master branch. > In case it fails, I will send you an instrumentation patch for > filenotify-tests.el.

In reality I don't expect any problem, because changed events appear more than once for a given change. As you could assume, I have no problems locally. I guess it is a problem of timing, but I don't want to increase the delays longer than they are. Yes, let's close this bug. Thanks for your patient testing!
