There is a check for other versioned formula with the same name
in the file audit. This just memoizes all of the versioned
formulae in a tap during the first call and then uses that much
shorter list everytime it checks for things.
We're seeing type errors when building formulae that use something
like `xcodebuild ..., "-arch", Hardware::CPU.arch`, since `CPU.arch`
is a symbol. We've been addressing these issues by calling `#to_s` on
the value but there was some talk about simply expanding the type
signatures to accommodate anything that will be cast to a `String`.
There's maybe still an argument to be made for doing string conversion
in formulae but expanding the type signatures will resolve a number of
existing type errors if we simply want to rely on implicit type
casting.
Past that, this also updates the type signature for `BuildError` to
align with the `#system` signature changes, as we receive a type error
otherwise.
This is needed to allow `Formula.all` to behave as expected when using
the API. Let's also (immediately, because it's broken) deprecate the
`CoreTap#formula_files` method.
Fixes#15122
The main thing is that this DSL allows us to provide an
interface that can be serialized to the JSON API.
Changes:
- Homebrew::Service
- Adds `#service_name` and `#plist_name` methods
- Each is now included in the `#serialize` method as well
- Eval block on instantiation
- Before we lazy evaluated this but the cost is not significant
and it complicated the code a bunch. This only gets called
during install, when evaluating caveats and in the `brew service`
command. It skips this evaluation if the service block isn't there.
- Add `#command?` helper to avoid `#command.blank?` and `#command.present?`
- Formula
- `#service` now returns a service whenever it's called. This call is
hidden behind a call to `#service?` most of the time anyway so this
should be fine.
- `#plist_name` and `#service_name` now call the methods of the same name
on the service class. This should have already been in the service object
to begin with and keeping these methods here helps preserve backwards
compatibility with people who were overwriting these methods before.
- Caveats
- Prefer `service#command?`
- Add helpers for checking on service commands
- This duplicates some of the work in `brew services`. Maybe we should
merge that repo in at some point.
- Check for installed service at `#plist_name` or `#service_name`. I think
this should be used instead of `Keg#plist_installed?` which checked for any plist file.
We should think about deprecating `#plist_installed?` in the future.
- Stop using `ps aux | grep #{formula.plist_name}` to check for service files
because it was inaccurate (it always returns true on my machine) because the grep
process is started before the ps process.
- Note: The behavior is the same as it was before. This means that caveats
only show up for custom service files on install or if they're already installed.
Otherwise it won't show up in `brew info`. This is because it has to check
first if the service file has been installed.
- Utils::Service
- Add utils for evaluating if a service is installed and running. This duplicates
some of the work already found in `brew services`. We should seriously consider
merging `brew services` with the main brew repo in the future since it's already
tightly coupled to the code in the main repo.
- Formulary.load_formula_from_api
- Be more explicit about which types can be deserialized into run params since
it is now possible for run params to be nil.
- Update and add tests
