This PR removes all remaining unnecessary cache clearing in tests
from the codebase since we now clear all cachable classes between
tests making this functionally unnecessary.
Original PR to automatically clear caches:
- https://github.com/Homebrew/brew/pull/16746
I also moved the `Utils::Analytics` module to use cachable so
that we don't have to clear caches specifically in tests anymore.
We have plans to add analytics for commands and `brew test-bot`
This requires a certain amount of refactoring which I've done here.
There was also a bunch of legacy `*_influx_?` usage from when we used
both InfluxDB and Google Analytics that made sense to clean up and
excessive indirection.
- roll InfluxDB token (we need to report to a new bucket to fix implicit schema)
- adjust various parameters
- separate default tags and fields
- send more fields and fewer tags (tags should have low cardinality)
- use `--data-binary` to match InfluxDB documentation
- document second precision for greater InfluxDB performance
- pass through tap name, formula/cask name, options separately
- pass `devcmdrun` as a tag
- avoid sending very high-cardinality `OS_VERSION` values
- Extract update tests into separate tests.
- Make `brew tests --online` run only once in its own job. This job
could be made non-required to fight flakiness.
- Split up the various macOS runs into several steps now that we have
more parallel macOS workers available.
- Cleanup some flaky tests.
- Use default `custom-prefix` label on macOS ARM (as `/usr/local` is
not the default).
- Add architecture (or Rosetta) to analytics event label.
- Don't send minor versions on Big Sur.
- Remove defunct `HOMEBREW_OSX_VERSION` reference.
