This PR mainly adds partition to our HTTP adapter. Additionally and perhaps most importantly, we've also taken the opportunity to move our 'conditional namespaces' deeper into the app.
The reason for doing this was, we like that namespaces should be thought of as required instead of conditional, 'special' things and would like the same thinking to be applied to partitions.
Now, instead of using code throughout the app throughout the adapters to add/remove namespaces or partitions depending on whether they are enabled or not. As a UI engineer you just pretend that namespaces and partitions are always enabled, and we remove them for you deeper in the app, out of the way of you forgetting to treat these properties as a special case.
Notes:
Added a PartitionAbility while we were there (not used as yet)
Started to remove the CONSTANT variables we had just for property names. I prefer that our adapters are as readable and straightforwards as possible, it just looks like HTTP.
We'll probably remove our formatDatacenter method we use also at some point, it was mainly too make it look the same as our previous formatNspace, but now we don't have that, it instead now looks different!
We enable parsing of partition in the UIs URL, but this is feature flagged so still does nothing just yet.
All of the test changes were related to the fact that we were treating client.url as a function rather than a method, and now that we reference this in client.url (etc) it needs binding to client.
Previously when namespaces were enabled, we weren't requesting permission for the actively selected namespace, and instead always checking the permissions for the default namespace.
This commit ensures we request permissions for the actively selected namespace.
We use a `<DataSource @src={{url}} />` component throughout our UI for when we want to load data from within our components. The URL specified as the `@src` is used to map/lookup what is used in to retrieve data, for example we mostly use our repository methods wrapped with our Promise backed `EventSource` implementation, but DataSource URLs can also be mapped to EventTarget backed `EventSource`s and native `EventSource`s or `WebSockets` if we ever need to use those (for example these are options for potential streaming support with the Consul backend).
The URL to function/method mapping previous to this PR used a very naive humongous `switch` statement which was a temporary 'this is fine for the moment' solution, although we'd always wanted to replace with something more manageable.
Here we add `wayfarer` as a dependency - a very small (1kb), very fast, radix trie based router, and use that to perform the URL to function/method mapping.
This essentially turns every `DataSource` into a very small SPA - change its URL and the view of data changes. When the data itself changes, either the yielded view of data changes or the `onchange` event is fired with the changed data, making the externally sourced view of data completely reactive.
```javascript
// use the new decorator a service somewhere to annotate/decorate
// a method with the URL that can be used to access this method
@dataSource('/:ns/:dc/services')
async findAllByDatacenter(params) {
// get the data
}
// can use with JS in a route somewhere
async model() {
return this.data.source(uri => uri`/${nspace}/${dc}/services`)
}
```
```hbs
{{!-- or just straight in a template using the component --}}
<DataSource @src="/default/dc1/services" @onchange="" />
```
This also uses a new `container` Service to automatically execute/import certain services yet not execute them. This new service also provides a lookup that supports both standard ember DI lookup plus Class based lookup or these specific services. Lastly we also provide another debug function called DataSourceRoutes() which can be called from console which gives you a list of URLs and their mappings.
This commit use the internal authorize endpoint along wiht ember-can to further restrict user access to certain UI features and navigational elements depending on the users ACL token
