Expose PluginLoader's get_plugin_class via PluginCache. PluginCache is
basically intented to act like a PluginLoader, except when instantiating
plugins, the "default" parameter values are taken form the cached
configruation, rather than the actual defaults defined in the Plugin's
parmaters.
Now that we add an event when logging errors, we need to avoid passing an
exception object directly to the logger. Otherwise we end up adding the
unserializable Exception object to the events list, which causes an error when
trying to write the output.
This maintains the default behaviour of bailing out immediately if any workload
fails in initialize(), but adds a setting, bail_on_init_failure, to change this
behaviour optionally. This can be useful where WA is being used more as a batch
processor.
Changes to the Status enum introduced by 31a535b5 and a9959550 broke
ran Jobs summary status at the end of the run. This fixes it so that the
total number of jobs and individual status counts are reported
correctly.
The generic "frequency" runtime parameter was only being set when there
are common frequences between avialable cores. It should always be set,
even if there are no frequencies in common, as it still valid to use it
with special values "min" and "max", in which case it should resolve
correctly to the appropriate frequencies.
Set context for the loggers of the Runner, the workloads and the
installed instruments and processors. Errors/warnings logged by these
entities will be automatically added as events.
Add ContextLogger wich extends logging.Logger's warning and error
methods to automatically add the message to the context's events (if a
context has been provided).
This enables you to do things like:
global:
runtime_parameters:
airplane_mode: true # This improves repeatability of energy measurements
workloads:
- name: foo
- name: bar
- name: geekbench
runtime_parameters:
airplane_mode: false # Geekbench requires network, and we don't care
# about energy for that workload anyway
For some reason I didn't look at the WA2 instrument until afer I
wrote this, so it's different in how it handles 'before/after'
quantities (which I called 'momentary' in the code) - instead of
adding a 'mean' it just adds two separate metrics: one for before and
one for after. Personally I think this is more useful (esp. for
temperature) but if necessary I can revert to the old behaviour.
This also doesn't add the helpful classifier telling you the hwmon
device, because we don't have immediate access to that info from the
devlib Instrument. If necessary I'm sure it could be added later.
Furthermore it doesn't have a parameter to filter the sensors, just
collects from them all.
Where backends have the capability to collect from multiple devlib
Instruments, EnergyMeasurement currently appends 'device' keys to the
names of metrics reported by those Instruments. Where multiple
Instruments are indeed used, it then sums up equivalent metrics to
produce the 'normal' metric without the 'device' keys
appended.
E.g. If you have two ACME 'devices' enabled you will get something
like
'device_total_energy_iio:device0' and
'device_total_energy_iio:device1', which will be summed to produce
'device_total_energy'.
However when only one Instrument is actually instantiated, this is
not needed and not done. Therefore just directly produce the metric
with the name originally given by devlib (i.e. in the example,
'device_total_energy').
Fully matching an APK resource requires the file to be present locally,
so that its metadata can be queries. HTTP getter was matching against a
remote path so the match was failing.
The matching now happens in two stages == first partial path-only
matches are established. Secondly, all partial matches are downloaded
and final match occurs against downloaded files.
