It's not sufficient to do this merely on `brew upgrade` because
`brew install` and `brew reinstall` can also result in formulae being
upgraded.
This requires moving logic from `cmd/upgrade.rb` to `upgrade.rb`. To
save you searching the diff the changes that resulted from doing that:
- Query the installed formulae from class state in `FormulaInstaller`
rather than the (incomplete) list that we passed into it.
- Don't output the "Checking dependents" message. It was there for
systems and configurations where this is slow but for most users
and most installations this will be a (annoying, noisy) no-op.
Fixes https://github.com/Homebrew/brew/issues/7860
More often than I realised, I want to `brew reinstall
--build-from-source --interactive $FORMULA` to add some custom
configuration. It seems like a useful addition?
This will become the default in a later version of Homebrew but has an
opt-out through HOMEBREW_NO_INSTALL_CLEANUP.
Also, always cleanup files older than 120 days and set the general
default value for "old" logs, casks etc. to 30 days.
After upgrading existing kegs, we now search and upgrade their
dependents as well. If any are detected that have broken linkage, they
are reinstalled from source.
If there are any formulae in the dependents tree that are pinned, they
are only reinstalled if they're not outdated; in all cases, a suitable
message is printed detailing the kegs that will be acted upon.
Consolidate the handling of which directories need to exist and which
need to be writable. Additionally, add a fatal check for formula
installations to ensure that any directories that need to be writable
are so before attempting an installation.
Fixes#4626.
It's not possible to determine the difference between a non-keg-only
keg that failed to link and one that wasn't linked by us intentionally.
To avoid additional complexity of storing this logic in another place
let's back out this relatively new functionality; sticky keg-only links
is a better and more desirable behaviour anyway.
Treat a `brew install` command as normal i.e. link by default unless
keg-only and only specify whether a keg should be linked when upgrading
or reinstalling. Also, adjust the naming accordingly so it's more
obvious that this is the case.
This means if a user has manually `brew unlink` or `brew link --force`d
something then that status will be preserved after they `brew upgrade`
or `brew reinstall` that formula.
This generally should make things that are keg-only by default easier
to swallow.
