ui: Fix metaData test as result of new consul-api-double (#6436) 2019-09-04 10:13:43 +01:00
John Cowen a1bebaba4a ui: Adds a `sort-control` component for asc/desc sorting of columns etc (#6034)
This adds the component but doesn't yet use it anywhere. No tests
are added here as there isn't an awful lot to test.

John Cowen 5cf063fc8a ui: Leader icon for node listing view (#6265)
- yarn upgrade consul-api-double which includes `status/leader`
- add all the ember-data things required to call a new endpoint
- Pass the new leader variable through to the template
- use the new leader variable in the template to set a leader
- add acceptance testing to verify leaders are highlighted
- Change testing navigation/api requests to status/leader (on the node listing page, status/leader is now the last get request to
be called).
- Template whitespace commit (less indenting)
- adds a test to to assert no errors happen with an unelected leader

John Cowen 429e27aaee ui: Enable blocking queries by default (#6194)
-Enable blocking queries by default
-Change assertion to check for the last PUT request, not just any request for session destruction from a node page.

Since we've now turned on blocking queries by default this means that a
second GET request is made after the PUT request that we are asserting
for but before the assertion itself, this meant the assertion failed. We
double checked this by turning off blocking queries for this test using

```
And settings from yaml
---
consul:client:
  blocking: 0
---
```

which made the test pass again.

As moving forwards blocking queries will be on by default, we didn't
want to disable blocking queries for this test, so we now assert the
last PUT request specifically. This means we continue to assert that the
session has been destroyed but means we don't get into problems of
ordering of requests here

John Cowen 834479d56f ui: Upgrade ember-cli-api-double. Adds new staging env (#6136)
ember-cli-api-double has been upgraded for 3 things:

1. Use the correct configuration flags
2. Automatically include the necessary files to enable the api doubles
without requiring a server. This can be disabled to provide custom
functionality (so we can stitch our BDD style testing in with this)
3. When used statically, read the cookies from the users browser to
enable basic ad-hoc double editing (e.g. CONSUL_SERVICE_COUNT=100000)

Once upgraded we've now moved the config to the correct place, added a
new environment (staging) to use the static-style of doubles
The test environment continues to use custom cookie setting and url
checking so we disable this 'auto importing' by setting 'auto-import' to
false for the configuration for the addon.

We also added a couple of new package script targets to explicitly serve
or build the UI with the entirely static UI.

John Cowen 5d2e1ce19b ui: Add `stats-card` component, integrate more `@hashicorp/structure-icons` (#6021)
1. Rebuild the heathchecked-resource component now we can copy and paste
2. As the above rebuild came with new icons, we also swapped out 'most'
of the other areas where we were using these new icons, plus any icons
that were effected by the new icon placeholders
3. Begin to remove more and more of the project specific icons (now
replaced by the shared ones)

John Cowen 011fb8a559 ui: Enable creating listeners using an object/hash (#5975)
Makes listening to multiple events on one target slightly easier.
Adding events can be rolled up into passing through an object, and the
returned remove function removes all of the handlers in the object

For example:

```
//this.listen...
const remove = listeners.add(
  {
    'message': handler,
    'error': handler
  }
);
remove(); // removes all listeners in the object
```

The entire API for listeners is now becoming slightly overloaded, so
potentially we'd use this API always and remove the ability to use a
string/function pair.

John Cowen 74dbc71c84 ui: Change vocab of ReopenableEventSource from 'reopen' to 'open' (#5973)
You can potentially close an EventSource before its first tick by
immediately setting the readyState to a non-open state. Therefore it
never opens.

Calling `open` will then open it.

'Open' fits better than 'reopen' when taking the above into account

John Cowen e1a8a28cd2 ui: Include yadda/gherkin dictionaries we use for acc testing (#5956)
Currently these gherkin dictionaries are contained in
`ember-cli-api-double`, which isn't the correct place for them.
They belong with the steps themselves.
This is also less complicated now we can require/import javascript
using a standard approach

Also runs an update of `ember-cli-api-double` which will be the last
installation of version 1 of this module.

John Cowen 3a14360da4 ui: Ensure an EventSource isn't opened if closed before first tick (#5703)
EventSources will wait for 1 tick before 'opening'. There is always the
chance that the EventSource is '.close()'ed before that tick. We
therefore check the 'readyState' before opening the EventSource

John Cowen 466c3c6899 ui: Allow text selection of clickable elements and their contents (#5770)
* ui: Allow text selection of clickable elements and their contents

This commit disables a click on mousedown be removing the `href`
attribute and moving it to a `data-href` attribute. On mouseup it will
only move it back if there is no selection. This means that an anchor
will only be followed on click _if_ there is no selection.

This fixes the fact that whenever you select some copy within a
clickable element it immediately throws you into the linked page when
you release your mouse.

Further notes:

We use the `isCollapsed` property here which 'seems' to be classed as
'experimental' in one place where I researched it:

https://developer.mozilla.org/en-US/docs/Web/API/Selection/isCollapsed

Although in others it makes no mention of this 'experimental' e.g:

- https://webplatform.github.io/docs/dom/Selection/isCollapsed/
- https://w3c.github.io/selection-api/#dom-selection-iscollapsed

I may have gone a little overboard in feature detection for this, but I
conscious of that fact that if `isCollapsed` doesn't exist at some point
in the future (something that seems unlikely). The code here will have
no effect on the UI. But I'd specifically like a second pair of eyes on
that.

* ui: Don't break right click, detects a secondary click on mousedown

* ui: Put anchor selection capability behind an ENV var

John Cowen f9710c2c92 ui: Reconcile ember-data store when records are deleted via blocking (#5745)
* ui: Reconciliate ember-data store when records are deleted via blocking

Currently we are barely using the ember-data store/cache, but it will
still cache records in the store even though technically we aren't using
it.

This adds a SyncTime to every record that uses blocking queries so we
can delete older records from the ember-data cache to prevent them
building up

* ui: Add basic timestamp method we can access from tests, fixup tests

Adds a timestamp method that we can access from within tests so we can
test that the SyncTime is being set.

There is probably a better way to do this, but this is also probably the
simplest approach - we are also likely to revisit this at a later date

ui: modify content path (#5950)
* Add ui-content-path flag

* tests complete, regex validator on string, index.html updated

* cleaning up debugging stuff

* ui: Enable ember environment configuration to be set via the go binary at runtime (#5934)

* ui: Only inject {{.ContentPath}} if we are makeing a prod build...

...otherwise we just use the current rootURL

This gets injected into a <base /> node which solves the assets path
problem but not the ember problem

* ui: Pull out the <base href=""> value and inject it into ember env

See previous commit:

The <base href=""> value is 'sometimes' injected from go at index
serve time. We pass this value down to ember by overwriting the ember
config that is injected via a <meta> tag. This has to be done before
ember bootup.

Sometimes (during testing and development, basically not production)
this is injected with the already existing value, in which case this
essentially changes nothing.

The code here is slightly abstracted away from our specific usage to
make it easier for anyone else to use, and also make sure we can cope
with using this same method to pass variables down from the CLI through
to ember in the future.

* ui: We can't use <base /> move everything to javascript (#5941)

Unfortuantely we can't seem to be able to use <base> and rootURL
together as URL paths will get doubled up (`ui/ui/`).

This moves all the things that we need to interpolate with .ContentPath
to the `startup` javascript so we can conditionally print out
`{{.ContentPath}}` in lots of places (now we can't use base)

* fixed when we serve index.html

* ui: For writing a ContentPath, we also need to cope with testing... (#5945)

...and potentially more environments

Testing has more additional things in a separate index.html in `tests/`

This make the entire thing a little saner and uses just javascriopt
template literals instead of a pseudo handbrake synatx for our
templating of these files.

Intead of just templating the entire file this way, we still only
template `{{content-for 'head'}}` and `{{content-for 'body'}}`
in this way to ensure we support other plugins/addons

* build: Loosen up the regex for retrieving the CONSUL_VERSION (#5946)

* build: Loosen up the regex for retrieving the CONSUL_VERSION

1. Previously the `sed` replacement was searching for the CONSUL_VERSION
comment at the start of a line, it no longer does this to allow for
indentation.
2. Both `grep` and `sed` where looking for the omment at the end of the
line. We've removed this restriction here. We don't need to remove it
right now, but if we ever put the comment followed by something here the
searching would break.
3. Added `xargs` for trimming the resulting version string. We aren't
using this already in the rest of the scripts, but we are pretty sure
this is available on most systems.

* ui: Fix erroneous variable, and also force an ember cache clean on build

1. We referenced a variable incorrectly here, this fixes that.
2. We also made sure that every `make` target clears ember's `tmp` cache
to ensure that its not using any caches that have since been edited
everytime we call a `make` target.

3. Provide 2 implementations of a Clipboard. One using clipboard.js (as

ui: Normal proxies link to services, sidecars to instances (#5944)
* ui: Normal proxies line to services, sidecars to instances

Following on from https://github.com/hashicorp/consul/pull/5933 we
noticed that 'normal' proxies should link to the service, rather than
the service instance. Additionally proxy 'searching' within the
repository should take into account the name of the node that the
originating service is on (sidecar proxies are generally co-located)

Added an additional test here to prove that a sidecar-proxy with the
same service id but on a different node does not show the sidecar proxy
link.

ui: Ensures nested policy forms are reset properly (#5838)
1. All {{ivy-codemirror}} components need 'refreshing' when they become
visible via our own `didAppear` method on the `{{code-editor}}`
component

(also see:)
- https://github.com/hashicorp/consul/pull/4190#discussion_r193270223
- 73db111db8 (r225264296)

2. On initial investigation, it looks like the component we are using
for the code editor doesn't distinguish between setting its `value`
programatically and a `keyup` event, i.e. an interaction from the user.
We currently pretend that whenever its `value` changes, it is a `keyup`
event. This means that when we reset the `value` to `""`
programmatically for form resetting purposes, a 'pretend keyup' event
would also be fired, which would in turn kick off the validation, which
would fail and show an error message for empty values in other fields of
the form - something that is perfectly valid if you haven't typed
anything yet. We solved this by checking for `isPristine` on fields that
are allowed to be empty before you have typed anything.

Previously we were creating a fake event and amending the name of the

approach to not use fake events, and allows you to overwrite the name
that the form uses for `handleEvent`

John Cowen 006b6000a8 UI: Add support for blocking queries on the service instance detail page (#5487)
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

John Cowen 45a2fa5a01 UI: Add blocking cursor validation and more straightforward throttle (#5470)
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.

John Cowen e0326c3b0a UI: Service Instances (#5326)
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

John Cowen 746201ed49 ui: Adds XHR connection management to HTTP/1.1 installs (#5083)
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
