Fixes#264
Implement the equivalent of java's String.hashCode on the conversation model.
Change avatar template and attributes. Use css classes for colors.
Clicking on a key conflict message opens the message detail view,
which displays the contact(s) in this conversation. If the message
contains a key conflict with any of these contacts, a button is
displayed which attempts to resolve that conflict and any other
conflicts in the conversation that are related to that contact.
Only re-render a message if the body changed. Re-render only the
delivery receipt checkmark if the delivered property changes.
Fix a bug where attachments flash in and out of existance when a
delivery receipt arrives.
Define a Whisper.View base class that automatically parses and renders
templates and attributes defined by the subclass. This saves us a good
number of lines of code as well as some marginal memory overhead, since
we are no longer saving per-instance copies of template strings.
The message view has three flavors so far, a normal text+attachments
message, a group update, and an end session message. This changeset
extracts the normal message rendering into its own subview, and adds
some convenience functions to the message model in order to simplify
some of that flavoring logic.
Uses app-level timestamps for outgoing messages.
Adds timestamp property to the outgoing jsonData.
Triggers a runtime event to notify frontend on delivery receipts.
Renders delivered messages with a 'delivered' class.
This change removes the timestamp field from messages and conversations
in favor of multiple semantically named timestamp fields: sent_at,
received_at on messages; active_at on conversations. This requires/lets
us rethink and improve our indexing scheme thusly:
The inbox index on conversations will order entries by the
conversation.active_at property, which should only appear on
conversations destined for the inbox.
The receipt index will use the message.sent_at property, for effecient
lookup of outgoing messages by timestamp, for use in processing delivery
receipts.
The group index on conversation.members is multi-entry, meaning that
looking up any phone number in this index will efficiently yield all
groups the number belongs to.
The conversation index lets us scan messages in a single conversation,
in the order they were received (or the reverse order). It is a compound
index on [conversationId, received_at].
This was used to conditionally render messages in the group style, but
it's actually unnecessary. We can render the same markup in both cases
and change the appearance with css.
Move base64 encoding of attachments to an AttachmentView. This makes
image rendering an asynchronous task so we fire an update event to
indicate to the parent MessageListView that its content has changed
height and it is time to scroll down.
Getting up and running with IndexedDB was pretty easy, thanks to
backbone. The tricky part was making reads and writes asynchronous.
In that process I did some refactoring on Whisper.Threads, which
has been renamed Conversations for consistency with the view names.
This change also adds the unlimitedStorage permission.
This dependency may be a little heavy for our current use case, but we can
roll with it for now and find something slimmer if it turns out yagni.
