A job stored its error and its result's warning as English text, much
of it built with the values in it (volume paths, a disk, libvirt's
error), so no catalog could translate it, and the job pages and panel
showed English whatever the language.
A job now stores them as messages: our English text, marked for
translation, and its values; libvirt's own text is a message without
values and is shown as it is. The jobs API and pages put them in the
reader's language. OperationError keeps its text and values apart for
the same reason, so a refusal raised while a job is submitted is shown
translated too. Messages one after another still read as sentences.
Errors stored before are kept as one message each, shown as they were.
The job panel on VM and storage pages wrote its buttons and notes in
English (Cancel, Open, Refresh, Dismiss, Finishing..., Files not
removed, Worker unavailable, Cancel failed) and its state badge as the
state's code, and the jobs API gave the phase untranslated. The panel
now takes its texts and the state labels from the page's settings, and
the API gives the phase in the viewer's language, as it gives the
label; the job pages show that phase.
A job that cannot be cancelled and ran past its time limit had
"(over its time limit)" written into its phase, which then matched no
translation. The phase stays as the job sets it, and the pages say the
job is past its limit.
Request jobs (an upload's chunks) run in gunicorn: their kind is admitted
running with the request as its worker, never claimed or recovered by the
worker, cancelled in the request, and asked by every housekeeping pass to
end its jobs that went idle. The panel can follow a job the page just
started. A job a request runs does not wait for the worker, so it does not
raise the worker-unavailable warning on the Jobs page or in the panel.
Only the request middleware loaded the Settings page values, so in the
worker process app_settings stayed empty: a VM create job failed reading
the default volume format, and the snapshot free-space check fell back to
its defaults. The worker now loads them before each job.
