test: replace symlinks with actual unit files During installation, meson complains: > Installing /home/zbyszek/src/systemd-work/test/units/sysinit.target to /var/tmp/systemd-test.Q1FSuj/root/usr/lib/systemd/tests/testdata/units > Warning: trying to copy a symlink that points to a file. This will copy the file, > but this will be changed in a future version of Meson to copy the symlink as is. Please update your > build definitions so that it will not break when the change happens. It *is* convenient to have those files as symlinks, but it is also confusing, because symlinks create aliases, and it seems that in those cases we actually don't want aliases (at least in the case of loopy*.service that'd make the test pointless).

test-path: start infinite sleep instead of a short command The test sometimes fails, e.g. in bionic-s390x ci. I think it might be because the service binary exits before we get a chance to notice that it is running: 13:59:31 --- Listing only the last 100 lines from a long log. --- 13:59:31 line 293: path-mycustomunit.service: state = exited;

test-path: use Type=exec In general, Type=exec is superior to Type=simple. Let's not assume that the service is started before it was really started.

core/path: recheck path specs when triggered unit changes state As documented in systemd.path(5): When a service unit triggered by a path unit terminates (regardless whether it exited successfully or failed), monitored paths are checked immediately again, and the service accordingly restarted instantly. This commit implements this behaviour for PathExists=, PathExistsGlob=, and DirectoryNotEmpty=. These predicates are essentially "level-triggered": the service should be activated whenever the predicate is true. PathChanged= and PathModified=, on the other hand, are "edge-triggered": the service should only be activated when the predicate *becomes* true. The behaviour has been broken since at least as far back as commit 8fca6944c2 ("path: stop watching path specs once we triggered the target unit"). This commit had systemd stop monitoring inotify whenever the triggered unit was activated. Unfortunately this meant it never updated the ->inotify_triggered flag, so it never rechecked the path specs when the triggered unit deactivated. With this commit, systemd rechecks all paths specs whenever the triggered unit deactivates. If any PathExists=, PathExistsGlob= or DirectoryNotEmpty= predicate passes, the triggered unit is reactivated. If the target unit is activated by something outside of the path unit, the path unit immediately transitions to a running state. This ensures the path unit stops monitoring inotify in this situation. With this change in place, commit d7cf8c24d4 ("core/path: fix spurious triggering of PathExists= on restart/reload") is no longer necessary. The path unit (and its triggered unit) is now always active whenever the PathExists= predicate passes, so there is no spurious restart when systemd is reloaded or restarted.
