If a service instance show page is being viewed and the service instance
is deregistered, this closes the blocking query for the proxy as well as
the instance (the instances query will be clsed on the error)
Also adds skipped tests to nag in future
Previously the tomography wasn't using ember `get` so proxy updates
(specifically here whilst receiving a blocking update) wasn't working.
This adds `get` here until we update to newer `get`less ember and also
refactors slightly removing `n` and using `distance.length` instead
Skipped tests are adding here to nag us to come back here at some point.
1. If the modal gets bigger than 80% of the viewport height a scrollbar
will be shown. Currently there isn't anywhere it can get this big, but
future work involves possible larger modals
2. Usually its difficult to figure out which was the 'unchecked' radio
button using an onchange event. Luckily ember/handlebars changes its
properties after the onchange event, so knowing that and using an extra
data-checked attribute set via ember, we can figure out which radio
button has been 'unchecked'. This means the logic for opening an
closing modals becomes slightly easier
...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.
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.
Also:
Add support for blocking queries on the service instance detail page
1. Previous we could return undefined when a service instance has no
proxy, but this means we have nothing to attach `meta` to. We've changed
this to return an almost empty object, so with only a meta property.
At first glance there doesn't seem to be any way to provide a proxy
object to templates and be able to detect whether it is actually null
or not so we instead change some conditional logic in the templates to
detect the property we are using to generate the anchor.
2. Made a `pauseUntil` test helper function for steps where we wait for
things. This helps for DRYness but also means if we can move away from
setInterval to something else later, we can do it in one place
3. Whilst running into point 1 here, we managed to make the blocking
queries eternally loop. Whilst this is due to an error in the code and
shouldn't ever happen whilst in actual use, we've added an extra check
so that we only recur/loop the blocking query if the previous response has a
`meta.cursor`
Adds support for blocking queries on the node detail page (#5489)
1. Moves data re-shaping for the templates variables into a repository
so they are easily covered by blocking queries (into coordinatesRepo)
2. The node API returns a 404 as signal for deregistration, we also
close the sessions and coordinates blocking queries when this happens

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.
* ui: Add forking based on service instance id existence
Proxies come in 2 flavours, 'normal' and sidecar. We know when a proxy
is a sidecar proxy based on whether a DestinationServiceID is set.
LocalServiceAddress and LocalServicePort are only relevant for sidecar
proxies.
This adds template logic to show different text depending on this
information.
Additionally adds test around connect proxies (#5418)
1. Adds page object for the instance detail page
2. Adds further scenario steps used in the tests
3. Adds acceptance testing around the instance detail page. Services
with proxies and the sidecar proxies and proxies themselves
4. Adds datacenter column for upstreams
5. Fixes bug routing bug for decision as to whether to request proxy
information or not
Add totals to some listing views, remove healthcheck totals
1. Adds markup to render totals for Services, Nodes, Intentions and v1
ACLs
2. Removes counts from healthcheck filters, and therefore simplify text,
moving the copy to the templates
3. Alter test to reflect the fact that the text of the buttons are no
static in the component template rather than a dynamic attribute
This gives more prominence to 'Service Instances' as opposed to 'Services'. It also begins to surface Connect related 'nouns' such as 'Proxies' and 'Upstreams' and begins to interconnect them giving more visibility to operators.
Various smaller changes:
1. Move healthcheck-status component to healthcheck-output
2. Create a new healthcheck-status component for showing the number of
checks plus its icon
3. Create a new healthcheck-info component to group multiple statuses
plus a different view if there are no checks
4. Componentize tag-list
* ui: Add ember steps:list command for listing available steps
1. Adds `command` addon to house the new command
2. Start to organize out the steps themselves, bring a bit more order to
things ready to dedupe and cleanup
- 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)
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
1. The factory is taken from the ember source, but makes it more
reusable
2. Purify converts conventional ember `computed` into a pure version
This commit only adds new files that could be used further down the line
`window` and `document` are easily injected anyhow, but this
primarily this keeps everything dom related in the same place.
Included here are changes to make all ember related objects use the dom
service `document` and `viewport` instead of just `document` and
`window`.
Quote from a previous PR (#4924) which explains the thinking around this:
> Now I have all these things in the dom service, it would make sense
to get window from there also. I was thinking of making a viewport
method, which would be a nice word whether window was a browser window,
an iframe (not really a window) like when ember testing, or anything
else. To me the viewport is what we are actually talking about here.
1. Ensure any unexpected developer errors are passed through/shown
2. Previously when errors where returns/resolved the special
isEnabled/isAuthorized would never get resolved. This was fine as they
were set to false to start with anyway, but this resolves them again to
false for completeness
3. Improved unit testing coverage
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.
- Adds full set of svg icons as CSS/Sass variables to the source
- Starts picking out some frame-grays, whilst commenting in possibles
- Remove color prefixing
The prefixes `ui-` and `brand-` for colors hav been removed. This makes
colors slightly easier to type.
In order to differentiate between brand colors and 'normal' colors, normal
colors are named as 'true colors' i.e. blue, red, green etc etc
whereas the brand colors used a more premium sounding name such as
'steel' for vault gray, 'magenta' for consul, 'cobalt' for vagrant etc etc.
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
The original version of ember-block-slots doesn't support ember 3 and it
seems like development has stalled on the original version.
This adds a modified version as an in-repo-addon that is compatible with
ember 3.
