Update unreadCounts per-conversation on incoming messages. Render unread
conversations with font-weigh: bold in the inbox view.
To ensure that the inbox and conversation views remain in sync, the
background page now ensures that the same models objects are used for
both views.
Templatize the inbox view and use the same pattern for in-window view
switching as is now used with the conversation/message detail views.
This means doing more with markup and less jquery manipulation of
individual subelements of the inbox view.
Closes#173
Previously, in the event of a failed websocket auth, we would attempt to
reconnect once a second ad infinitum. This changeset ensures that we
only reconnect automatically if the socket closed 'normally' as
indicated by the code on the socket's CloseEvent. Otherwise, show a
'Websocket closed' error on the inbox view.
Ideally we would show a more contextual error (ie, 'Unauthorized'), but
unfortunately the actual server response code is not available to our
code. It can be observed in the console output from the background page,
but programmatically, we only receive the WebSocket CloseEvent codes
listed here:
https://developer.mozilla.org/en-US/docs/Web/API/CloseEvent#Status_codes
The websocket error message is displayed by a normally-hidden but ever
present socket status element. Clicking this element will immediately
refresh the background page, which will try again to open the websocket
connection.
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.
Although I find the previous implementation more elegant, it results in
a deeper nesting of Promises than necessary, which can make debugging
more complicated. The canvas scaling and compression apis are actually
synchronous, so the callback structure isn't really recessary here.
Converting to a loop also makes this process easier to understand at
a glance.
Fixed some bugs along the way:
* accidentally scaling small images up to 1920px
* jpeg compressing gifs and other formats even if unnecessary
Previously we would not scale large resolution images with small file
sizes, but in fact, both resolution and file size constraints should be
enforced.
Converting attachment data to base64-encoded data uris takes O(n) and
there's no need! URL.createObjectURL returns a magic link that can be
set as the `src` attribute to `img`, `video`, and `audio` tags to load
blob data directly without copying.

Add contentType-specific limits, switch to lazy-init iff we encounter an
oversized file, and restyle as a toast, factoring out a generic
ToastView along the way.
Wait a little longer on initial scroll down. Previous timeout sometimes
triggered before all text is finished rendering.
Remove redundant resize calls.
Background page conversations were trying to trigger events on the inbox
list view which had been destroyed, resulting in a background page
console error of "can't read innerHeight of null".
Avoid this by removing listeners when the inbox window is closed.
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.
The first message sent to a new contact was throwing 'Unknown Group'.
This was because we didn't wait for the initial save to sync the `type`
attribute to indexedDB. Instead, don't trigger the conversation to open
until it has finished saving.
This is an artifact of a time when conversation elements would pop in
and out of the dom at a moment's notice, and thus needed to rebind their
event listeners regularly.
When a new message arrives, if its conversation is not already opened,
the background page opens it. If it is alrady open the window is
focused. Finally, the 'message' event is triggered, resulting in
1. the inbox refetches conversations
2. all conversations fetch new messages
TODO: only send this event to the target window
This collection is just an in-memory indexer used for typeaheads. For
display, the matching models are added to a separate collection. Thus,
the order of the elements in the typeahead collection does not matter.
It feels a little weird when you can't see the matching member. Would
consider putting this back in if we display the member list in the
contact list item view.
