Misko Hevery e32b6256ce fix(core): QueryList should not fire changes if the underlying list did not change. (#40091) ... Previous implementation would fire changes `QueryList.changes.subscribe` whenever the `QueryList` was recomputed. This resulted in artificially high number of change notifications, as it is possible that recomputing `QueryList` results in the same list. When the `QueryList` gets recomputed is an implementation detail and it should not be the thing which determines how often change event should fire. This change introduces a new `emitDistinctChangesOnly` option for `ContentChildren` and `ViewChildren`. ``` export class QueryCompWithStrictChangeEmitParent { @ContentChildren('foo', { // This option will become the default in the future emitDistinctChangesOnly: true, }) foos!: QueryList<any>; } ``` PR Close #40091		2021-01-14 13:55:02 -08:00
