...also:
Temporarily overwrites native setTimeout and setInterval for e2e/acceptance
testing similar to how XHR is overwritten for e2e/acceptance testing.
This makes the blocking query acceptance tests run faster until we add a
better burstable rate limiter for blocking queries.
More recommendations for blocking queries clients was added here:
https://github.com/hashicorp/consul/pull/5358
This commit mainly adds cursor/index validation/correction based on
these recommendations (plus tests)
The recommendations also suggest that clients should include rate
limiting. Because of this, we've moved the throttling out of Consul UI
specific code and into Blocking Query specific code. Currently the 'rate
limiting' in this commit only adds a sleep to every iteration of the
loop, which is not the recommended approach, but the code here organizes
the throttling functionality into something we can work with later to
provide something more apt.
- Maintain http headers as JSON-API meta for all API requests (#4946)
- Add EventSource ready for implementing blocking queries
- EventSource project implementation to enable blocking queries for service and node listings (#5267)
- Add setting to enable/disable blocking queries (#5352)
Move all the dom-things to use the dom service in tabular-collection, feedback-dialog, list-collection and node show. Move get-component-factory into utils/dom and use dom.root() in a few more places
This includes an additional `dom.components` method which gives you a
list of components matching the selector instead of just one.
This does several things to make improving the search experience easier
moving forwards:
1. Separate searching off from filtering. 'Searching' can be thought of
as specifically 'text searching' whilst filtering is more of a
boolean/flag search.
2. Decouple the actual searching functionality to almost pure,
isolated / unit testable units and unit test. (I still import embers get
which, once I upgrade to 3.5, I shouldn't need)
3. Searching rules are now configurable from the outside, i.e. not
wrapped in Controllers or Components.
4. General searching itself now can use an asynchronous approach based on
events. This prepares for future possibilities of handing off the
searching to a web worker or elsewhere, which should aid in large scale
searching and prepares the way for other searching methods.
5. Adds the possibility of have multiple searches in one
template/route/page.
Additionally, this adds a WithSearching mixin to aid linking the
searching to ember in an ember-like way in a single place. Plus a
WithListeners mixin to aid with cleaning up of event listeners on
Controller/Component destruction.
Post-initial work I slightly changed the API of create listeners:
Returning the handler from a `remover` means you can re-add it again if you
want to, this avoids having to save a reference to the handler elsewhere
to do the same.
The `remove` method itself now returns an array of handlers, again you
might want to use these again or something, and its also more useful
then just returning an empty array.
The more I look at this the more I doubt that you'll ever use `remove`
to remove individual handlers, you may aswell just use the `remover`
returned from add. I've added some comments to reflect this, but they'll
likely be removed once I'm absolutely sure of this.
I also added some comments for WithSearching to explain possible further
work re: moving `searchParams` so it can be `hung` off the
controller object
