brew/Library/Homebrew/test/cmd, branch 1.2.3

tests: cleanup tests.

2017-06-07T15:25:07+00:00

Remove pending tests that are never run on CI (i.e. require `--online`),
remove fixtures for those tests and just make `--official-cmd-taps`
run by `--online` instead.

Add test for `brew style`.

Improve some `brew install` messaging.

2017-05-27T09:15:37+00:00

Improve the messaging around `brew install` when there's a possible user
action such as an `upgrade` or `link` and don't tell people to
`install --force` when it's unnecessary.

While I did this, tweak the output and function usage in a couple of
related places.

Some example output before this change:
```
Warning: openssl is a keg-only and another version is linked to opt.
Use `brew install --force` if you want to install this version
Warning: mysql@5.6 is a keg-only and another version is linked to opt.
Use `brew install --force` if you want to install this version
Warning: analog-6.0_1 already installed
Warning: bash-completion@2-2.5 already installed, it's just not linked.
```

Some example output after this change:
```
Error: openssl 1.0.2k is already installed
To upgrade to 1.0.2l, run `brew upgrade openssl`
Warning: mysql@5.6 5.6.36_1 is already installed
Warning: analog 6.0_1 is already installed
Warning: bash-completion@2 2.5 is already installed, it's just not linked.
You can use `brew link bash-completion@2` to link this version.
```

Remove `to_s` from some `Pathname`s.

formula_installer: improve install/upgrade message

2017-04-25T11:45:39+00:00

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If you `brew install` an outdated formula that's installed you get: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the formula isn't outdated use the previous message.

Add `GitHub::search_code` method.

2017-04-25T10:29:01+00:00

search: use single HTTP call for tap searches.

2017-04-24T13:11:04+00:00

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.

Fix and remove various TODOs.

2017-04-23T14:10:18+00:00

Fix those that can be done so without tearing Homebrew to pieces and
remove the comments for those that can never be done.

tests: reduce some noise.

2017-04-22T11:49:14+00:00

- Tweak the way offline skipping happens
- Skip more tests that break when offline
- Hide more stdout output from tests.

Fix the 'export PATH' message in `link` for a keg-only formula

2017-04-02T03:12:00+00:00

Commit 4cae6a724e6d684eb157dd6d7328755694f228b2 introduced the message,
but it printed the wrong path, e.g. for `brew link sqlite`:

```
If you need to have this software first in your PATH instead consider running:
  echo 'export PATH="/usr/local/opt/sqlite:$PATH"' >> ~/.zshrc/bin
```

where `/bin` is appended at the end, but should be inserted before
`:$PATH`: `echo 'export PATH="/usr/local/opt/sqlite/bin:$PATH"' >> ~/.zshrc`.
This patch fixes that and updates a test to verify it.
