In a previous iteration of discovery-chain wrapping some event listeners
in a call to `next` (i.e. do this on next tick) was necessary. We added
a comment in here to see if we could get rid of it at a later date.
We've taken another look at this and it looks like this `next` is no
longer required in this later iteration. Further more there is the
tiniest chance that possibly, as we are adding listeners on next tick, that the
listeners could be added after component destruction, which means when
you click on the page we try to set a property of a destroyed object and
boom.
Removing this `next` removes this tiny possibility.
* ui: Remove custom css-vars 'polyfill' and use native CSS props
Previously we used a sort of polyfill for certain places where we needed
CSS property-like behavior. This meant duplicating code between JS and
CSS, specifically some of our SVG icons.
We moved to CSS props only in the places where they are beneficial and
populated the variables with our already existing SASS variables.
This means we no longer have to duplicate CSS and we can remove our
custom css-var helper/polyfill.
During the refactor of the data layer we had a method that you can use
to do a request/response call i.e. adapter.request > serializer.respond
We weren't sure what to name this but eventually wanted it to live on
the HTTPAdapter itself (see removed comments in the changeset)
We've decided `rpc` is a good name and we've moved this to where we want
it. We've deprecated the old `request` method name but not removed it as
yet. There's also opportunity now to reduce the 'read/write' functions
further as they essentially do the same thing. Again we've left this for
the moment, but we are hoping to get the code for our custom Adapter down
to less than 100 LoC.
* Return early from updateGatewayServices if nothing to update
Previously, we returned an empty slice of gatewayServices, which caused
us to accidentally delete everything in the memdb table
* PR comment and better formatting
go test will only run tests in parallel within a single package. In this case the package test run time is exactly the same with or without t.Parallel() (~0.7s).
In generally we should avoid t.Parallel() as it causes a number of problems with `go test` not reporting failure messages correctly. I encountered one of these problems, which is what prompted this change. Since `t.Parallel` is not providing any benefit in this package, this commit removes it.
The change was automated with:
git grep -l 't.Parallel' | xargs sed -i -e '/t.Parallel/d'
This is useful when updating an config entry with no services, and the
expected behavior is that envoy closes all listeners and clusters.
We also allow empty routes because ingress gateways name route
configurations based on the port of the listener, so it is important we
remove any stale routes. Then, if a new listener with an old port is
added, we will not have to deal with stale routes hanging around routing
to the wrong place.
Endpoints are associated with clusters, and thus by deleting the
clusters we don't have to care about sending empty endpoint responses.
