1. EventSources now pass themselves thorugh to the run function as a
second argument. This enables the use of arrow functions along with the
EventSources API
`(configuration, source) => source.close()`. Order of arguments could
potentially be switched at a later date.
2. BlockingEventSources now let you pass an 'event' through at
instantation time. If you do this, the event will immediately be dispatched
once the EventSource is opened. The usecase for this is for 'unfreezing' cached
BlockingEvents. This makes it easier to provide a cache for
BlockingEventSources by caching its data rather than the entire
BlockingEventSource itself.
```
new BlockingEventSource(
(config, source) => { /* something */ },
{
cursor: 1024, // this would also come from a cache
currentEvent: getFromSomeSortOfCache(eventSourceId) //this is the new bit
}
);
// more realistically
new BlockingEventSource(
(config, source) => { return data.findSomething(slug, config) },
getFromSomeSortOfCache(eventSourceId)
);
```
consul-ui
Prerequisites
You will need the following things properly installed on your computer.
- Git
- Node.js (with npm)
- yarn
- Ember CLI
- Google Chrome
Installation
git clone https://github.com/hashicorp/consul.gitthis repositorycd ui-v2yarn install
Running / Development
The source code comes with a small server that runs enough of the consul API as a set of mocks/fixtures to be able to run the UI without having to run consul.
make start-apioryarn start:api(this starts a Consul API double running on http://localhost:3000)make startoryarn startto start the ember app that connects to the above API double- Visit your app at http://localhost:4200.
To enable ACLs using the mock API, use Web Inspector to set a cookie as follows:
CONSUL_ACLS_ENABLE=1
This will enable the ACLs login page, to which you can login with any ACL token/secret.
You can also use a number of other cookie key/values to set various things whilst developing the UI, such as (but not limited to):
CONSUL_SERVICE_COUNT=1000
CONSUL_NODE_CODE=1000
// etc etc
See ./node_modules/@hashicorp/consul-api-double for more details.
Code Generators
Make use of the many generators for code, try ember help generate for more details
Running Tests
Please note: You do not need to run make start-api/yarn run start:api to run the tests, but the same mock consul API is used.
make testoryarn run testmake test-vieworyarn run test:viewto view the tests running in Chrome
Running Tests in Parallel
Alternatively, ember-exam can be used to split the tests across multiple browser instances for faster results. Most options are the same as ember test. To see a full list of options, run ember exam --help.
Note: The EMBER_EXAM_PARALLEL environment variable must be set to override the default parallel value of 1 browser instance in testem.js.
To quickly run the tests across 4 parallel browser instances:
yarn test-parallel
To run manually:
$ EMBER_EXAM_PARALLEL=true ember exam --split <num> --parallel
More ways to split tests can be found in the ember-exam README.md.
