As part of resolving a resource, record its MD5 hash in the output
metadata. In order to enable this, resource resolution is now done via
the context, rather than directly via the ResourceResolver (in order not
to introduce a context dependency in the Gui object, context now
emulates the resolver interface).
Metadata is a key-value mapping for arbitrary data, similar to
classifiers. Unlike classifiers, metadata does not directly relate to
the results of the execution, but to the execution itself, and typically
would not be processed by Output Processors in the same way as
classifiers. Metadata can also be a lot more free-form in it's value
structure; while classifier values are simple scalars, metadata values
can be arbitrary POD structures.
If the device is to perform an initial reboot, allow up to `max_retries`
from the run configuration for the reboot to succeed and add logging to
inform the user.
Treat the optional reboot of the device as part of the job itself so that
if the reboot fails it will be retried in accordance to the job
configuration.
Instead of starting and stopping the target from inside the Context,
move the calls to the Runner. This allows for the any initilizaton
errors to be dealt with as part of the job and retried as
appropriate.
- expose pluginloader's resolve_alias in plugin_cache (it's supposed
to be a transparent proxy for pluginloader).
- resolve aliases inside _set_plugin_defaults() to make sure the
correct defaults are used when creating job specs.
Expose the RebootPolicy as an attribute of the ExectionContext and ensure
that that the target is not automatically rebooted if the reboot
policy is set to "Never".
Rename the parameter to be clearer on the effect of the policy, as this
will cause WA to reset the device for each new job it runs regardless of
the iteration number.
We only need to deploy the gui once, therefore move the `deploy` method
call into `initialize` the corresponding `remove` method is already in
`finalize`.
- Have the job manage the indent of each of its stages
- Switch output_processor to using indentcontext
- Move the "Configuring augmentations" log line into Job -- the
rest of the stages are logged there, but this was done by the
Executor for some reason.
Add hostid entry, as reported by busybox's hostid applet, to TargetInfo.
This is intended to be a "unique 32-bit identifier for the current
machine". In practice, it may not be set, or may be generated from
something like an IP address, so may not be unique. However, if set, it
is still likely to be more unique than kernel/os version so may be worth
recording.
Replace Target.cpuinfo, which contained parsed contents of
/proc/cpuinfo, with a list of more comprehensive CpuInfo objects which
include cpufreq and cpuidle information as well.
- Use indentcontext inside initialize_run to make sure log level
is dedented on error.
- Ensure Executor postamble always runs, event if runner errors.
- Fix format_duration() to handle sub-second timedeltas.
Add a function to return WA version suffixed with the commit hash for
current HEAD. This only works if WA was deployed via
python setup.py develop
otherwise, the output is identical to get_wa_version().
When scanning modules for plugins, only consider classes defined in that
module, but not those imported into it. This will prevent log output
being polluted with repeated "Skipping..." messages for imported plugin
bases.
Move the logging of the WA version and command line used to invoke it
from run command into main() inside entrypoint. That way, these will be
the first entries in the log file, now that early log records are no
longer lost.
If more then one of augmentation entries ("augmentations",
"instrumenatation", "output_processors") is specified in the same
config they were being merged into a single entry.
This can cause issues with '~~' (drop everything glyph) being "resolved"
during this merge and therefore not actually used to drop all previous
augmentations.
Union'ing, instead of merging, configs at the same level avoids that.
Note that this is semantically correct, as we're not enforcing
precedence at the same level of config, so merge semantics do not apply.
Add support for "~~" special value that indicates that, when merging
into another set, all values from that set should in fact be dropped.
Apart from the unique merge semantics, "~~" just like any other "~"
value.
Delay the split of augmentations into instruments and output processors
until they are actually being accessed; keep them as a single set until
then. This makes tracking of merges from various configurations sources
easier
If WA is ran without any workloads being specified, previously an index
error was thrown, now check that at least one global workload has been
specified and if not, provide a more helpful error message.
Add extra_plugin_paths setting which gets populated from WA_PLUGIN_PATHS
environment variable. This allows specifying additional locations to
scan for WA plugins.
The `install_timeout` variable is used to allow extra time when
installing an apk, if the apk is not present on the host system it
will be pulled back to the host, therefore we should allow extra time
when transferring the file in the other direction as well.
If the http getter is used but a connection is not avalible, when
attempting to fetch the resource index an error will be raised. Now we
ignore the error allowing for the remaining getters to be used.
Ensure that boot and runtime parameters always get initialized to an
obj_dict even when not explicitly specified. This will ensure they get
serialized and deserialized properly.
Catch exceptions raised when attempting to set value of a config point,
and re-raise as ConfigError with name associated with the value in the
config file.
Now allows a `prefer_host_package` parameter to be set to control
whether a package located on the host system (`True`) or on the target
(`False`) should be favoured during resolution.
`pull_apk` now returns the path to the apk it pulled from the device so
WA can keep track of it and avoid conflicts with other apks present
on the host.
Upon initilisation WA3 will now also check if a WA3 config file
exisits, rather than just the exsistance of the config directory.
If a `config.yaml` file is not found WA will look for a WA2 config.py
file and convert it to the new format, otherwise a default config file
will be generated.
Record UI state if an error occurs during setup, run, and output
processing stages (for other stages, the UI state is unlikely to be
relevant as they typically would not include UI manipulation).
Only run finalize() for a job if initialize has succeed. finalize()
should be able to assume that initialize() has succeed, without needing
to check that that file have been created, variables set, etc.
Fix an issue where AndroidWorkload.pull_apk would sometimes get the
wrong package if the desired package name is a substring of another
package name. Rather than using a regex to match the package name, use
the new get_package_info method to match the name exactly.
Hitting CTRL-C will abort execution of the current job, but will still
trigger run finalization, and possibly, post-processing and teardown of
the current job. If an exception is raised during this
post-process/teardown, the previous exception state (for the
KeybardInterrupt) will be clobbered. That means that, after the new
exception has been handled, WA would attempt to execute the next job,
rather than go to finalization of the run.
To avoid this, set a flag in the context upon catching KeybardInterrupt,
and check this flag before attempting to execute the next job in the
queue.
Rather than relying on a custom Logger with a context to add events when
they are logged, have the runner register hooks for corresponding
signals that do that.
The issue with the previous approach is that the event ended up
being added too late -- after the current job was already cleared, so
all events were added at run level.
With the new approach, the event will be added when it is first logged,
while there is still a current job being set. There will be no
duplication for Exceptions being re-raised and handled at different
levels because log_error() will ensure that each Exception is logged
only once.
- Add SimpleTargetDescriptor that simply returns a global list of target
descriptions.
- Add create_target_description function to populate that list with a
description crated from the specified components.
- Add add_description_for_target helper function to create a description
for the specified target class, and specified components. For
components that are not explicitly specified, attempt to guess
sensible defaults based on the target class' bases.
- fix TargetDescription._set to set lists rather than dicts for params
to be consistent with how params are set after creation (should
probably get rid of this entirely...)
- fix the comment describing the structure of TARGETS
- Keep track of logged exceptions inside log_error itself.
- signal: log the exception, if there is one in the finally clause of
the signal wrapper; this will ensure that the error will be logged
closer to the command that originated.
- entrypoint: use log.log_error for top-level error logging, rather than
the entrypoint logger directly; this will ensure that errors are not
repeated unnecessarily.
- Log CTRL-C message at zeroth indent level to make it easier to see in
the non-verbose output where it occurred.
If a target error occurs, check whether the target is unresponsive. If
it is, attempt to hard reset it if possible, or gracefully terminate
execution if not.
Add a method to check that the target is still responsive, and cache
the value so that the target does not need to be repeatedly probed
during various stages of wrapping up execution.
ExecutionContext.end_run() does final updates to the run info in the run
output (final status, run duration, etc). This was previously accessed
via self.output in the context. Typically, this would correctly resolve
to the run output, as there would be no current job. However, in the
event of a crash, current_job would be set, and this would resolve to
the job output itself, resulting in run info not being updated. Use
run_output to avoid this.
