e0976fde2c bump(electron): 0.34.3 => 0.35.1
Electron 0.35.1 includes the tray fixes we contributed last week but also includes API restructuring and improvements. Most importantly, modules from electron are now imported via `require('electron')`

b2f8b34a32 feat(counts): Unread counts for all folders and labels across all accounts
Summary:
This diff replaces the UnreadCountStore with a better approach that is able to track unread counts for all folders/labels without continuous (and cripplingly slow) SELECT COUNT(*) queries.

When models are written to the database, we currently don't send out notifications with the "previous" state of those objects in the database. This makes it hard to determine how to update counters. (In the future, we may need to do this for live queries). Unfortunately, getting the "previous" state is going to be very hard, because multiple windows write to the database and the "previous" state we have might be outdated. We'd almost have to run a "SELECT" right before every "REPLACE INTO".

I created an API that allows you to register observers around persistModel and unpersistModel. With this API, you can run queries before and after the database changes are made and pluck just the "before" state you're interested in.

The `ThreadCountsStore` uses this API to determine the impact of persisting a set of threads on the unread counts of different labels. Before the threads are saved, it says "how much do these thread IDs contribute to unread counts currently?". After the write is complete it looks at the models and computes the difference between the old count impact and the new count impact, and updates the counters.

I decided not to attach the unread count to the Label objects themselves because 1) they update frequently and 2) most things observing the DatabaseStore for categories do not care about counts, so they would be updating unnecessarily.

The AccountSidebar now listens to the ThreadCountsStore as well as the CategoryStore, and there's a new preference in the General tab for turning off the counts.

Test Plan: Tests are a work in progress, want to get feedback first!

0b84942051 perf(db): Lazily deserialize models on the other side of the action bridge
Summary:
We send database `trigger()` events through the ActionBrige to all windows of the app. This means that during initial sync, we're serializing, IPCing and unserializing thousands of models a minute x "N" windows.

This diff converts the payload of the trigger method into an actual class that implements a custom toJSON. It converts the impacted `objects` into a string, and doesn't deserialize them until it's asked.

Bottom line: this means that in many scenarios, we can avoid creating Contact models, etc. in composer windows only to broadcast them and then gc them.

Test Plan: No new tests yet, but this should definitel be tested. #willfix.

ad5274049d fix(databse): fix memory leak on DatabaseStore.atomically
Summary:
The Promise chain we were creating was never cleared and created a memory
leak. We instead use a `PromiseQueue` to cleanup finished promises.

Also added several more tests and verified that the memory leak is gone
with the Chrome profiler

Test Plan: new tests
