add guard in Formula#file_modified? to prevent git popup
add guard in Superenv.bin before calling MacOS::Xcode.version
add guard against missing Xcode/CLT in Xcode.uncached_version
return nil instread of 0 in uncached_version when Xcode/CLT are not present, to distinguish from linuxbrew behavior
checks against pour_bottle? and needs_relocation?, add guard around keg.relocate_install_names to check pour_bottle?/needs_relocation? as well
needs_relocation? becomes skip_relocation?, use cellar attr to indicate relocation instead of does_not_need_relocation
MacOS.can_build? becomes MacOS.has_apple_developer_tools?
Add these new errors, and guards in formula installation and
cmd/{,un,re}install to match, move can_build? to the MacOS module,
flatten conditions, remove redundant can_build? check
reinstate removed (doctor) check
Check @@attempted for cctools so that we only attempt the relocation
install once, skip cxxstdlib check in cctools to prevent otool
execution prior to installation, skip fixing install names if
relocation is not required
Install it as a dependency unless already satisfied by Xcode.
require cctools_requirement
cctools_requirement should be satisfied by cctools present in opt
add build_env => false to the satify block options in CctoolsRequirement

After the formula gets renamed oldname opt is created and
it points to the linked keg. However if we then upgrade newname
oldname opt still points to the same keg it pointed before upgrade.
The commit fixes this behaviour thus that oldname opt links at the
same keg opt point.
Change behavior for `brew cleanup` as follows:
- If `--force` is supplied, remove only outdated keg-only packages.
- If `--prune=<days>` is supplied, remove both logs and cached downloads
older than the specified number of days. Use `--prune=all` to remove
all logs and cached downloads irrespective of age.
- By default, remove logs after 14 days and cached downloads never.
Also centralizes handling of `--prune`, thus removing duplicate logic.
This is motivated by commit 17eee232838d4639b25f863aa342b1dda61b81bc
that made `--force` much more aggressive and made it override whatever
was specified via `--prune`, completely removing all:
- outdated keg-only packages
- cached downloads irrespective of age
- logs irrespective of age
This made it impossible to remove outdated keg-only packages without
also deleting all cached downloads, which is at least inconvenient for
people with limited bandwidth wanting to rebuild packages later.
ClosesHomebrew/homebrew#42970.
