[State Management] State syncing utilities - remove AppState from Dashboard app #54105

Dosant · 2020-01-07T11:35:15Z

Summary

~~Depends on #53582~~
Part of #44151
Removes AppState from dashboard app and replaces it with state containers and state syncing utilities.

There is also follow up in progress which also removes global state:
#55158

Disclamer

I didn't try to refactor the state management in Dashboard in scope of this (as new state_containers give us more flexibility).
Just tried to replace AppState -> State Containers with minimal changes

Nothing major, but probably worth looking into: If full screen mode is toggled by changing the state in the rison encoded URL parameter, data gets fetched again. I looked into this a bit and it seems like the query object gets changed triggering an angular watcher. In the current setup this doesn't happen for some reason. This could probably be handled by comparing the current state and the deserialized state from the URL and not changing the object reference if the two are deep equal.

Some nits, but dashboard integration LGTM - works great, thanks! There is one difference I noticed but it's not a blocker for merging this. I noticed that requests are triggered in a lot of places when they are not necessary (e.g. when changing "showMargins" setting), but this is also happening on master. I will create a separate issue for that.

@flash1293, Good catch! this particular case is fixed by utilising "applyDiff" utility from old state_management in new state syncing utils.

Now it seems like, that it happens only when filters are applied, likely is going to be fixed together with:

Tested and reviewed code LGTM
However, for the protocol, why did this change require adding getPendingUrl and supporting returning undefined from update in kbn_url_storage

src/legacy/core_plugins/data/public/filter/filter_manager/filter_state_manager.ts

@@ -80,7 +84,7 @@ export class FilterStateManager {

  private saveState() {
    const appState = this.getAppState();
-    if (appState) appState.save();
+    if (appState && appState.save) appState.save();


Why would we get an appState without a save method?

This filter_state_management is still used in Dashboard (until next pr, where we will remove global state also)
So, as we removed AppState from Dashboard, I change the interface of filter_state_manager to :
https://github.com/elastic/kibana/pull/54105/files/10fe7772a3297f9e5b03591dd9d47a5b8ca9be02#diff-e99af5c3c776f37f6e37ab25d094e3cfR25

And save function is for legacy AppState case, but new state sync utils don't have explicit save() method.

@lizozom,

However, for the protocol, why did this change require adding getPendingUrl and supporting returning undefined from update in kbn_url_storage

I don't remember exactly the edge case I was fighting, but in a nutshell it was something like this:

const state1 = {...}; // initial state
const state2 = {...}

setState(state2) // transition to state2, the location change was scheduled 
setState(state1) // synchronously transition back to state 1, but location change wasn't scheduled, because comparison inside stateSync util took storageState from current location.

// so we ended up in state1, but url with state2 :(
