Repurpose upload script to read natively generated histogram json.
This script will be used when tests write proto-backed JSON. It still has to reside source-side because we need to access the catapult Python API to get at HistogramSet and reserved_infos, etc. WebRTC tests will write proto-backed JSON, and this script can read it because the Histogram class has been made capable of doing it. Build information diagnostics are added, and then we upload in the old JSON format (the dashboard can read the new format as well, but there's no reason to implement export to the new format at this point). We could imagine more outlandish solutions where the test binaries themselves do the uploading, but then we would have to pass the build information to them, and they would have to upload from the shards. Alternatively, we could pass build information to tests so they write it right into the histograms. This solution is probably the best one for now since it's 1) consistent with how Chromium does it 2) flexible in the right ways 3) we don't have to worry if uploading from shards even works.

"""Converts and uploads results to the Chrome perf dashboard.
|
||||
"""Adds build info to perf results and uploads them.
|
||||
|
||||
This conversion step is needed because test/testsupport/perf_test.cc can't
|
||||
output histograms natively. There is, unfortunately, no C++ API for histograms.
|
||||
This script is in python so it can depend on Catapult's python API instead.
|
||||
See histogram_util.py for how this is done. We should move to the C++ API and
|
||||
delete the scripts in this dir as soon as there is a C++ API (less conversions =
|
||||
easier to understand).
|
||||
The tests don't know which bot executed the tests or at what revision, so we
|
||||
need to take their output and enrich it with this information. We load the JSON
|
||||
from the tests, add the build information as shared diagnostics and then
|
||||
upload it to the dashboard.
|
||||
|
||||
This script can't be in recipes, because we can't access the catapult APIs from
|
||||
there. It needs to be here source-side.
|
||||
|
||||
This script is adapted from the downstream variant like this:
|
||||
* Follows upstream naming conventions.
|
||||
* Downstream-only parameters and concepts go away.
|
||||
* oAuth tokens are generated by luci-auth.
