This commit includes several pieces of functionality to enable services
to be removed and the page to present information that this has happened
but also keep the deleted information on the page. Along with the more
usual blocking query based listing.
To enable this:
1. Implements `meta` on the model (only available on collections in
ember)
2. Adds new `catchable` ComputedProperty alongside a `listen` helper for
working with specific errors that can be thrown from EventSources in an
ember-like way. Briefly, normal computed properties update when a
property changes, EventSources can additionally throw errors so we can
catch them and show different visuals based on that.
Adds xhr connection managment to http/1.1 installs
This includes various things:
1. An object pool to 'acquire', 'release' and 'dispose' of objects, also
a 'purge' to completely empty it
2. A `Request` data object, mainly for reasoning about the object better
3. A pseudo http 'client' which doens't actually control the request
itself but does help to manage the connections
An initializer is used to detect the script element of the consul-ui sourcecode
which we use later to sniff the protocol that we are most likely using for API access
Repositories are a class of services to help with CRUD actions, most of
the functionality is reused across various Models. This creates a new
repository service that centralizes all this reused functionality.
Inheritance via ember `Service.extend` is used as opposed to
decorating via Mixins.
1. Move all repository services (and their tests) to a
services/repository folder
2. Standardize on a singular name format 'node vs nodes'
3. Create a new 'repository' service to centralize functionality. This
should be extended by 'repository' services
ui: Repo layer integration tests for methods that touch the API
Includes a `repo` test helper to make repetitive tasks easier, plus a
injectable reporter for sending performance metrics to a centralized metrics
system
Also noticed somewhere in the ember models that I'd like to improve, but left
for the moment to make sure I concentrate on one task at a time, more or less:
The tests currently asserts against the existing JSON tree, which doesn't
seem to be a very nice tree.
The work at hand here is to refactor what is there, so test for the not
nice tree to ensure we don't get any regression, and add a skipped test
so I can come back here later
