+++ This bug was initially created as a clone of Bug #837668 +++

We need to measure when the app is usable by the user. For that we'll need to send an event (the moment is specific to the app) to |window| that the performance test will be able to receive.

The events for implementation are outlined in bug 996038.
Bug 996038 introduces new events outlining the phases of application startup. Each of these 5 events needs to be implemented.
Summary: [Contacts] "ready to use" perf measurement → [Contacts] Implement new startup loading events
As an FYI, this implementation needs to land in 2.0 as it is important for meeting release performance acceptance criteria.
Hi Eli,

have some doubts about when to launch the events cause of the nature of the contact app.

As we load the list content dynamically, but we allow the user to interact before this list is done, even the first contact is displayed, should we launch mo-content-interactive when the user is ready to interact with the frame (add contact and settings) or when the very first contact is displayed in the list?

Assignee: nobody → francisco
From looking at the Contacts app, Add Contact and Settings are elements that exist within the chrome of the application. That means when these elements are ready to be interacted with, you will trigger 'moz-chrome-interactive'.

I would consider the Contact list to be the core interaction of the application, and so once the user is able to start interacting with the list (regardless of whether there are any contacts in the list or not), then you should trigger 'moz-content-interactive'.

Does that make sense?
Flags: needinfo?(eperelman)
Definitely, makes sense since the interaction with the list is key,  so we will fire the event when we draw the first screen with contacts.

This list is really tricky since it doesn't load completely, but the user can interact at the very moment we display the first batch of contacts.

Need to add the app to the whitelist at [1].

Thanks for that, I read it but forgot to add to the PR.

Also here is a summary of the events used with this PR:

- moz-chrome-dom-loaded fired when we receive the 'load' event in index.html
- moz-chrome-interactive fired when setup the listeners on the first elements on the screen: search, add contact and settings
- moz-app-visually-complete fired when we remove the class 'hide' fromt he body
- moz-content-interactive when the first batch of contacts is rendered
- moz-app-loaded just after we fired the moz-content-interactive since the contacts will be loading, but the app is totally usable.
