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.
This changes the API method's current behavior by not automatically
maximizing (in `overlayed` view mode) or bringing a background chat into
foreground (in `fullscreen` view mode). Instead `force` needs to be set
to `true` for that to happen.
Set reference to roster contact on the message and chatbox object and
listen for changes to the nickname.
Currently, because chat boxes are fetched and initialized before the
roster, messages and chats are repainted with the correct display name
only later, causing a "flash" effect.
Ideally we would only initialize the chat boxes after the roster
contacts have been fetched, but this is currently not easily possible
because we need the control box to render before everything else.
* Replace `tearDown` overrides with event handlers.
* Move presence listeners to `connected` event handler, otherwise they
don't get called when logging in again after disconnection.
* Add `clearSession` listeners to clean up upon disconnection.
* Use `Promise.all` instead of listening for multiple events.
We distinguish between UniView and MultiView instances.
UniView means that only one chat is visible, even though there might be multiple ongoing chats.
MultiView means that multiple chats may be visible simultaneously.
This reverts commit 7af73c3471.
Doesn't look like the right approach for adding support for XEP-0156.
Work on that will continue in a branch in the meantime.
* Return the promise, so that we can wait.
* `sendContactAddIQ` now returns a promise and doesn't take a callback
* Don't call `destroy` on a contact that's already been removed.
