470429 - nsPlacesDBFlush::onItemAdded should not sync if the item is a container

Status: RESOLVED FIXED

(Toolkit :: Places, defect)

Description

[Marco Bonardo [:mak]]

we are doing more work than needed, onItemAdded should sync places only if we create an uri item, containers don't use moz_places table

apart this, i was thinking that if we are in a batch we should not sync onItemAdded and onItemChanged... but i fear that could cause issues for longer batches, so for now i'm not doing that.

How would that cause issues for longer batches?  We don't want to do any syncing during batches right?

if we crash in the middle of a batch, we could end up with lot of orphan bookmarks. suppose that the batch is an undo of the deletion of 100 bookmarks, hwv i think for that could make sense go with a followup

And we should be doing that from within a transaction, so if we crash, sqlite will roll that back when we next open the database.

test_history_removeAllPages.js needs to be fixed contextually to this push since it relies on sync count

patch v2.1

Low risk; small scope - reduces the number of times we sync to disk
