- Signoffs were just a stopgap until we implemented getting "real"
reviews for a user via the GitHub API. They were a suboptimal way of getting
reviews because they only really exist in Homebrew/homebrew-core where
BrewTestBot adds signoffs for each maintainer who reviewed the PR.
- This will stop the `Style/Documentation` filepath includes getting out of
sync with what we declare as a public API, thus ensuring that everything is
documented.
- Maybe we could also add a job here to check that _all_ the paths in the
RuboCop config still exist, but that's for another time.
- This `Homebrew/utils.rb` file contains one `@api public` method so it's now
included in `Style/Documentation`.
- This method not having a comment was causing the style specs to fail because
this file isn't usually failing RuboCop.
- And the test description was confusing so I improved it.
Passing the strategy symbol into the `#from_url` `select` block
means that we can also get rid of a `#from_symbol` call in a
different conditional branch, as we can directly compare the
`livecheck_strategy` symbol to `strategy_symbol`.
When the `Json` strategy was introduced, I forgot to also ensure
that it's only treated as usable (in `Strategy#from_url`) if a
`livecheck` block uses `strategy :json`. As a result, `Json` is
incorrectly treated as a usable strategy for all formulae/casks that
contain a `strategy` block.
Since all of these `livecheck` blocks specify a strategy, this bug
doesn't meaningfully impact livecheck's behavior (i.e., these checks
continue to use their explicitly-specified strategy). The only
practical difference is that `Json` incorrectly appears in the list
of usable strategies in livecheck's verbose JSON output.
This commit modifies `Strategy#from_url` to address this issue. The
easiest way to enforce this rule involved passing in the
`@strategies` key (a symbol) into the `select` block, so we can
compare it to `livecheck_strategy` (the strategy symbol specified in
the `livecheck` block).
