Use master/worker terminologi in arguments

timj · 2018-01-16T18:59:21Z

xdist/dsession.py

        self._active_nodes = set()
        self._failed_nodes_count = 0
-        self._max_slave_restart = self.config.getoption('max_slave_restart')
+        self._max_slave_restart = self.config.getoption('max_worker_restart')


It would be better if the code was also changed to use worker rather than slave. Does this code also support the old command line option to stop everything breaking during transition?

No, I just renamed to new method. Do you need support old value? I'll add support

I'm not in charge here, but I think it would be best if a deprecation notice is used for the old command so that it is still supported for a couple of releases before being dropped.

It would be better if the code was also changed to use worker rather than slave

I didn't change another code bacause it must be changed in pytest repo else. Do you think I need rename all code?

I meant, can we stop using "slave" in the xdist code everywhere, and not just in the messages seen by users? Using worker externally and slave internally seems like a weird inconsistency when the aim is to remove slave nomenclature everywhere. I wasn't saying anything about other pytest repos.

PS Thanks for tackling this. I really do appreciate this getting done since I haven't had a chance to have a go myself.

Ok, I'll remove all "slave" from code, but there is one file which uses in pytest. So, I need to create commit in pytest repo else

@feuillemorte you mean the slaveinput attribute of the config object? I think for that case we can have both names, slaveinput and workerinput which point to the same dictionary so we can keep backward compatibility.

@nicoddemus ok, thank you!

nicoddemus

Thanks a ton @feuillemorte for tackling this, we really appreciate it.

Please see my comments. 😁

             "host system")
-    group.addoption('--max-slave-restart', action="store", default=None,
-                    help="maximum number of slaves that can be restarted "
+    group.addoption('--max-worker-restart', action="store", default=None,


IIRC you can pass multiple values here to support aliases:

group.addoption('--max-worker-restart', '--max-slave-restart', action="store", ...

I want to add dest value like:

group.addoption('--max-worker-restart', '--max-slave-restart', action="store", default=None, dest="maxworkerrestart", help="maximum number of workers that can be restarted " "when crashed (set to zero to disable this feature)\n" "'--max-slave-restart' option is deprecated and will be removed in next versions")

Seems good, perhaps just changing "in next versions" to "in a future release". 👍

Please, test locally. Tests ran successfuly, but.. :)

Please add an alias here for backward compatibility:

# deprecated name, backward compatibility only self.slaveinput = workerinput

this dict also need the old names (slaveid and slavecount)

and we likely need to keep those for around 5 years at least

i propose adding as is and later on following up with a dict subclass that gives deprecation warnings in a few years

Ah good catch, I missed those. 👍

how to use linter? :)
tox -e linting ERROR: unknown environment 'linting'

nicoddemus · 2018-01-17T20:30:51Z

how to use linter? :)

tox -l shows all environments, in pytest-xdist the linter is called flakes:

tox -e flakes

Thanks @feuillemorte for the quick update!

LGTM so far, let's wait for @RonnyPfannschmidt's review.

feuillemorte · 2018-01-18T09:11:28Z

@timj please, approve too

Related to #234

nicoddemus · 2018-01-30T21:13:50Z

Added an explicit test for backward compatibility of the old slaveinput name.

RonnyPfannschmidt

i believe we covered all that needs covering now
so this is good to go, thanks 👍

i do have a lingering fear that a minor detail is missing, but thise should be sortable very easily

RonnyPfannschmidt · 2018-02-06T09:49:28Z

@feuillemorte great work, thanks again 👍

ionelmc · 2018-02-26T12:44:18Z

Do we really need to also rename the --max-slave-restart? I don't really like the churn of editing config files in a dozen projects.

nicoddemus · 2018-02-26T13:13:10Z

--max-slave-restart was kept as an alias to --max-worker-restart:

pytest-xdist/xdist/plugin.py

Lines 29 to 30 in 63b329c

    
           group.addoption('--max-worker-restart', '--max-slave-restart', action="store", default=None,
