Review Request 227: Don't attempt to force the role to a state

Repository: rolekit Description ------- Previously, when we started up we would check whether a role was in the state we expected it to be (ready-to-start or running) and start or stop it if it didn't match our expectation. This is the wrong behavior; we need to be reporting the real state and not arbitrarily altering the system. (For example, someone may have chosen to stop one of the services through systemd for a good reason).

Review Request 232: Update Vagrantfile for Fedora 23
by Stephen Gallagher 25 Nov '15

----------------------------------------------------------- This is an automatically generated e-mail. To reply, visit: http://reviewboard-fedoraserver.rhcloud.com/r/232/ ----------------------------------------------------------- Review request for RoleKit Mailing List, Miloslav Trmac, Nils Philippsen, Stephen Gallagher, and Thomas Woerner. Repository: rolekit Description ------- Also add workaround for docker bug The docker bug is that in many cases (including the Vagrant case), Docker 1.8.2 (the current version in the stable repository) will fail to initialize on first startup. So this patch forces us to use the known-good 1.7.0 from the Fedora 23 frozen package set in order to do the first-time initialization, then we update to the latest version. This part of the patch can be reverted once 1.9.1 lands in the stable repository, since it seems to fix the issue. Diffs ----- Vagrantfile 27230401a49f10756198f6153080938b655153e3 contrib/vagrant/rolekitdev-bootstrap.sh 43f374b9f6ddff22b7f80c6abd18ce1425bae125 Diff: http://reviewboard-fedoraserver.rhcloud.com/r/232/diff/ Testing ------- Built and tested changes for reviews 226-231 with `vagrant rsync && vagrant provision` using this new vagrant box. It worked properly. Thanks, Stephen Gallagher

The class doesn't implement any part of the dict interface, nor does any code seem to use the dict interface on any of its objects.

Should we care if units is a real list, rather than an object that is sequence-like enough to `extend()` and existing list? I just dropped this assertion. I think it was a leftover from an earlier version of that function. > On Nov. 16, 2015, 3:40 p.m., Nils Philippsen wrote: > > src/rolekit/server/rolebase.py, lines 1321-1336 > > <http://reviewboard-fedoraserver.rhcloud.com/r/231/diff/2/?file=1220#file122…> > > > > How about: > > > > ``` > > # == Create the [Unit] Section == # > > unitfile['Unit'] = { > > 'Description': self._desc, > > 'Requires': tuple(self._requirements), > > 'BindsTo': tuple(self._requirements), > > # All roles are also assumed to require the network, so > > # we will start it after network.target > > 'After': "network.target", > > } > > > > # == Create the [Install] section == # > > unitfile['Install'] = { > > 'RequiredBy': tuple(self._requirements), > > # All roles are enabled for the multi-user.target > > 'WantedBy': "multi-user.target", > > } > > ``` Honestly, I find that considerably less readable than my version. - Stephen ----------------------------------------------------------- This is an automatically generated e-mail.

Just from looking at the code, I think it should work but I still think it would be cleaner if we kept the state as `SYSTEMD` so it's explicit that one needs to consult systemd (whether by listening to signals or polling) to find out the state of the target. AIUI, this state gets saved to the JSON file in `/etc/rolekit/roles`, and I'd like it better if none of "must consult systemd" states are ever persisted there. OK, so it turns out that there was actually only one case where it would get written out to disk: in the deferred role processing. I've modified that code so that it will always explicitly set the state to NASCENT before writing out the deferred settings JSON. I then modified rolesettings.py to only set the SYSTEMD state if something other than NASCENT or ERROR is present in the settings data. I've examined the rest of the code and with the exception of deferred processing, settings.write() is never called anywhere before change_state(), so SYSTEMD should never appear in the file. > On Nov. 16, 2015, 3:19 p.m., Nils Philippsen wrote: > > src/rolekit/server/io/systemd.py, lines 63-69 > > <http://reviewboard-fedoraserver.rhcloud.com/r/230/diff/2/?file=1208#file120…> > > > > That's pretty minimalistic. Are you sure you don't want to put this in a later commit that adds a little code? ;) This was leftover from a first implementation that I ultimately scrapped but forgot to remove. New version of the patch corrects this. > On Nov. 16, 2015, 3:19 p.m., Nils Philippsen wrote: > > src/rolekit/server/io/rolesettings.py, line 30 > > <http://reviewboard-fedoraserver.rhcloud.com/r/230/diff/2/?file=1207#file120…> > > > > This bogus import comes from review #226.
