There was a previous discussion about making `brew linkage --test` fail
for unrequested dependencies (#9172). I'm not sure what the outcome of
that was, but it still seems like a good idea to try to help us find
cases of opportunistic linkage as they happen rather than when they
cause CI failures in another PR sometime later.
Let's do this by adding a `--strict` flag to `brew linkage --test`. My
intention is for `brew linkage --test --strict` failures to be warnings
rather than errors in CI, which should mitigate some of the concerns
about doing this that were raised in #9172.
Add a `--print-path` flag to `brew edit`, in order to print the source `.rb`
file of both casks and formulae. In order to prevent faulty reporting, `brew
formula $SOME_CASK` will now error out if a cask matches, but a formula does
not.
Remove all code related to Bintray. It no longer works so there's no
point keeping it around.
Some of this could arguably be deprecated/disabled first/instead but:
I'm not sure I see the sense in keeping stuff around that's known to be
broken.
