Goal is to fix a timing bug that results in `show` being triggered
before the `ChatBoxView` has been initialized, which means that 1:1
chats aren't opened when you reload the page.
Depend on latest backbone.browserStorage which has support for IndexedDB
via localforage.
Storage operations are now asynchronous and transactional.
Bugs fixed (mostly by waiting for operations to complete):
* Rooms are now fetched asynchronously, so wait before triggering `show`
or when closing.
* Make sure chat create/update transactions complete before firing events
* Make sure chats and messages have been fetched before creating new ones.
* When doing a `fetch` with `wait: false` on a collection and then
creating a model in that collection, then once the read
operation finishes (after creating the model), the collection is emptied again.
* Patch and wait when saving.
Otherwise we have previously set attributes overriding later ones.
* Make sure api.roomviews.close returns a promise
Test fixes:
* Chats are now asynchronously returned, so we need to use `await`
* Wait for the storage transaction to complete when creating and updating messages
* Wait for all chatboxes to close
Otherwise we get sessionStorage inconsistencies due to the async nature of localforage.
* Wait for room views to close in spec/chatroom.js
In the process, remove the `closeAllChatBoxes` override in
converse-controlbox by letting the `close` method decide whether it
should be closed or not.
Instead optimize in other ways.
Also:
- Don't fade in when `animate` is false.
- `trimChats` now gets called in `afterShown`.
- Add now event `beforeShowingChatView`
- new config option `singleton`.
- new plugin `converse-uniview`
- removed `converse-embedded`.
- various CSS changes, to properly render an embedded full app
- don't re-open cached and non-autojoined chats in singleton mode
The goal here is to extend the `embedded` `view_mode` so that the full app can
also be embedded, not just a single MUC or private chat.
To do this, we'll need to differentiate between multi and singleton chat apps.
* A singleton chat app contains only a single chat.
* A multi-chat app can contain zero or more chats
So we introduce a new config option, `singleton`, which when used with
`view_mode` set to `embedded` will determine whether a single chat or the full
app is embedded.
Similarly, in `overlayed`, `fullscreen` and `mobile` view modes, `singleton`
set to true will allow only one chat within the parameters of that view mode.
We're appropriating the word `singleton` and introducing the concepts of
`uniview` and `multiview` (see a785ca8) to cover what was
previously meant with `singleton`.
