The hope is that this will be clearer and less annoying for users.
A user came to us a couple weeks ago stating that it was confusing
that the `brew upgrade` command printed an error when a pinned
formula had a new version available and didn't get upgraded.
This PR changes that message to a warning from an error. While looking
into this we found that there is another message that gets printed
when a package dependency doesn't get upgraded because it is pinned
and that got turned into a warning from a normal message. Honestly,
that should be more worrying for the user anyway; it could lead to
a program not working correctly in the worst case.
I also added a message to the `brew pin` command warning about
potential unintended behavior if a dependency gets pinned and another
package requires a newer version of it.
Lastly, I added a commented out deprecation notice for the
`brew upgrade --ignore-pinned` command since it's now the default.
Let's start storing `revision` and `pkg_version` for tab runtime
dependencies and use them when available.
When the `revision` is not available, use a conservative approach to
deciding whether dependencies need to be upgrade.

Download the bottle manifests for the potential formulae we are going to
upgrade and, if they are have all their `runtime_dependencies` versions
currently met, don't try to download the bottle or upgrade the formula.
We upgrade dependents of upgraded formulae to make sure that an upgrade
doesn't break anything. However, this reasoning applies only when a
dependent is bottled, since attempting a source build is just as likely
to break things, if not more.
I've opted not to restrict this to, say, users only on outdated versions
of macOS in order to cleanly handle other cases where this change should
also apply: Linux, or current versions of macOS in a non-default prefix.
Output hints for disabling automatic `brew update`, `brew cleanup` and
`brew upgrade`/`brew reinstall` of dependents. Also provide a
`HOMEBREW_NO_ENV_HINTS` to disable this messaging.
There's a few bits of functionality that Homebrew has changed over the
years, makes sense as a sensible default but some people find really
annoying:
- automatically running `brew update`
- automatically running `brew cleanup`
- automatically upgrading outdated dependents
- automatically reinstalling broken dependents
For each of these: let's improve the documentation of the commands
whose behaviour is changed and the environment variables themselves.
Ensure that we don't try to check for broken linkage in a keg that
doesn't exist. Furthermore, fix the reason we checked for the keg that
doesn't exist by `Formula.clear_cache`.
While here, I noticed that there was other methods of caching at use in
`Formula` so consolidate them to be consistent.
