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are only reinstalled if they're not outdated; in all cases, a suitable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.
Previously if a `brew reinstall` was Ctrl-Cd after some files had been
installed it wouldn't try to remove the partially installed keg and the
renaming of the backed-up keg would fail. Alternatively, remove the
partially installed keg as if it has been Ctrl-Cd or otherwise failed
then it's not desirable to keep it.
This is the same that happens in the command 'install'. By passing
the invalid option names, we enable the formula installer to output
warnings if necessary.
If `--with-foo` is provided to a formula through a tab or through
another formula depending on it and this option does not exist it
should be filtered. If it is not (the prior behaviour) then this can
prevent bottles being used unnecessarily.
Fixes#1399.
Since we are loading options as Formula#build from tab, we will have to explicitly read
options from ARGV as well.
Fixes#3066.
Closes#537.
