A few tweaks to the public doc comments, thanks!

+ * cached locally.


I think this statement is misleading as it gives indication that having documents in the cache will retrieve documents stored in the cached and go to the backend when not in cache.

Consider instead "This collector tries to ensure lowest memory footprints from the SDK, at the risk of documents not being cached for offline queries or for direct queries to the cache."

+
+  createPersistence(cfg: ComponentConfiguration): Persistence {
+    const lruParams =
+      this.cacheSizeBytes !== undefined


wondering if we need a range check for this.cacheSizeBytes > 0

This actually won't work because we use -1 to disable GC.

I really do not like this approach, we should do something similar to the new cache config API, using a dedicated enum branch to disable GC. Maybe something for the fixit week.

Not sure if ending // were intentional

Ah, I hate it when my editor does this and i don't know how to stop it.

+    persistence: MemoryPersistence,
+    lruParams: LruParams | null
+  ): MemoryLruDelegate {
+    return new MemoryLruDelegate(persistence, lruParams!!);


what is the double exclamation at the end of lruParams!! do? I'm not familiar with the double.

It tells complier that you are sure this is a LruParams, not a null. I removed | null in this case, it was not neccessary.

+          .removeExpectedTargetMapping(query1)
+          // should get no events.

Is the test name and the test implementation aligned on this one? Maybe I'm not following what it's trying to assert

Nope, fixed.

Thank you!

@hsubox76

Please take a look, I need owner's approval for something outside of firestore. I do not understand why they show up though, they seem to be generated automatically.

Check some changes under:

common/
docs-devsite/
packages/auth/api-extractor.json

They are all auth-related.

hsubox76

Sorry about auth.api.md. I made a PR to ensure it's reverted after docgen is run but this branch may have been created before that: #7014 You can just revert it.
Can you add a changeset? It should be @firebase/firestore minor and firebase minor (the yarn changeset CLI should help you add the first automatically, the second has to be added manually)

Done, thanks!

These should be minor as it's changing the API.

Fixed, thanks.

 ): MultiClientSpecBuilder {
  const specBuilder = new MultiClientSpecBuilder();
-  specBuilder.withGCEnabled(withGcEnabled === true);
+  specBuilder.ensureManualLruGC();


Shouldn't this be:

if (withGcEnabled !== true) { specBuilder.ensureManualLruGC(); }

Oh yeah, thanks for checking this.

I intended to delete withGcEnabled all together, because multitab will always have lru gc. I just forgot to delete it.
