- only document HOMEBREW_* variables in the manpage (although still
read from all the original environment variables).
- resort manpage environment variables in alphabetical order
- check the original path for trailing slashes
If people have `HOMEBREW_RUBY_PATH` set then things explode in a rather
confusing fashion. Instead, run `bundle` for them with the arguments
that they'd want.
Also, move `macho` requires into the module itself; it's a pain having
to do everything for Bundler before requiring `pathname` which is a core
Ruby class.
Homebrew's actually ended up using a fair few gems. While we want to
avoid Bundler at runtime (and this PR still does that, in fact uses
Bundler even less at runtime than it did before) writing our own version
to use at build-time seems redundant.
Also, don't delete them after that. This means that `brew postinstall`
becomes a way to easily reinstall configuration files for any formula
without needing any changes to any bottles or requiring a reinstall.
If you `brew install` a formula that's already installed you get:
Warning: ripgrep-0.5.1 already installed
If you `brew install` an outdated formula that's installed you get:
Error: ripgrep-0.5.1 already installed. To install this version, first
`brew unlink ripgrep`
Instead, suggest that the user should `brew upgrade` in this case. If
the formula isn't outdated use the previous message.
Use GitHub's code search API to search using the filename based on the
search query. This means we only need a single HTTP call and no more
multithreading madness. This also means we're able to search everything
in the Homebrew and Caskroom organisation by default without having to
maintain a list of things to search (and not) in here.
Another attempt at fixing `brew audit` issues around detecting
`revision` and `version_scheme` changes correctly. First done in #1754
and #2086 (reverted in #2099 and #2100).
To ease future debugging a `ph` helper has been added to print a hash
and a series of RSpec tests to verify that the `revision`,
`version_scheme` and `version` formula version audits behave as
expected.
Fixes#1731.
Hide these tokens to avoid malicious subprocesses e.g. sending them
over the network. Also, support using these tokens with environment
filtering and clear `HOMEBREW_PATH` from subprocesses to stop them
sniffing it. Finally, use `HOMEBREW_PATH` to detect Homebrew’s user’s
PATH for e.g. `brew doctor` etc.
Deprecate more methods. Internal APIs have been verified to be unused
elsewhere and removed. External APIs have had deprecation methods added.
Existing deprecations have been either upgraded to produce warnings or
no longer deprecated and the reasoning documented.
