The `#versions_from_content` method requires a regex and this will be
enforced by the type signature, so we don't have to check for the
presence of a regex when handling a `strategy` block.
The initial documentation comments contained some remaining text
referring to `GithubLatest` and hadn't been updated to incorporate
the recent changes to the aforementioned strategy. This also reworks
some of the language to better explain the strategy's function,
application, etc.
`GithubLatest` was updated to use parts of `GithubRelease` and this
works fine within `brew livecheck` (since we `require` all the
strategies) but we need to explicitly `require` `GithubRelease` in
the `GithubLatest` test file now. Without this, we encounter errors
in parts of `GithubLatest` where `GithubRelease` is referenced.
There are two reasons for this:
- Makes it easier to run this command as a sanity check without
having to create a temporary directory
- Is somewhat faster since you don't have to write thousands of files
The default curl args in `#curl_headers` cover most of
`Livecheck::Strategy::DEFAULT_CURL_ARGS` but `--max-redirs` was
overlooked. This adds an explicit `--max-redirs` argument in
the `#page_headers` `#curl_headers` call but it's worth mentioning
that this approach wouldn't benefit from any changes in
`DEFAULT_CURL_ARGS` and would need to be manually kept in parity.
It now checks for two new edge cases.
1. Are the required methods defined in the block?
2. Is the `run` command defined if we're using methods other
than `service_name` or `plist_name`?
It has also been updated to only get the list of method call nodes
once instead of doing it repeatedly for each cellar path check.
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
