what is buildbucket_service? if you are thinking of creating a generic client that might be useful for others as well, let's talk.

I don't have in mind making this a super generic/reusable client. At least not from the start.

These "services" in:
https://cs.chromium.org/chromium/src/third_party/catapult/experimental/soundwave/services/

are all just thin wrappers around APIs for services in speed/benchmarking we use to write some command line tools (e.g. pinpoint_cli to start pinpoint try jobs, or soundwave to get data from chrome perf dashboard).

As an example of a tool I'm hoping to write (I had an equivalent in the older buildbot world) is a "grep" like tool to look through the logs of recent runs of a particular benchmark or test case to search e.g. for a particular error message and figure out where it started occurring. But that will be pretty much tied to how performance_test_suite works, so not really that general.

Anyway, happy to set a GVC meeting if you want to talk more.

i see. For prpc protocol, here is a reference implementation https://cs.chromium.org/chromium/infra/luci/appengine/components/components/prpc/client.py

[cli services] Add buildbucket_service

The service will be used to access information about builds and builders
running in our waterfalls.

Also removing the old (unfinished) version based on legacy buildbot
APIs.
