Explanation
This PR add a new
EventQueue
shared class util to the@metamask/profile-sync-controller
package.We are using this to ensure user-storage updates are executed and fulfilled in the actual order they were called.
For now, this is used for account syncing when reacting to
AccountsController
accountRenamed
andaccountAdded
events.This addition has been made in reaction to a recent change to extension code that made it so that when a user adds a new account, without changing the default name, both
accountAdded
andaccountRenamed
were fired.This induced race conditions where we weren't in control of which user-storage request would land first.
With this change, we raise back our confidence to 100%.
