Rather than asking for a global target, the message receiver implements
the EventTarget interface itself. It does not expose the dispatchEvent
method, however. This ensures that events can only be triggered from
within the internal MessageReceiver class, which means we no longer need
to namespace them.
// FREEBIE
Let the libtextsecure consumer pass in their own server url, username,
password, and signaling key, as with libtextsecure-java.
Also brings reconnect logic up into the MessageReceiver class, which
is the only place it should apply.
Encapsulate the global conversation cache collection against accidental
access, avoiding the data-clobbering bug fixed in previous commit.
Also move some one-off program initialization code from panel controller
to background.js
// FREEBIE
Only fetch them from a frontend view. If the conversation is not open,
we don't need to load the messages, and if we do load them, they will
render before we've done the initial contact info loading (as
implemented in 74e96ce).
Fixes#344
// FREEBIE
The delivery receipt handler should only update messages, so rather than
reloading the conversation and its contacts, only reload the messages.
// FREEBIE
This trigger function uses chrome's runtime message passing api, which
traverses between different windows in our runtime, but we only trigger
the updateInbox event from the backgroud page, so we don't need to use
that api, which requires some extra cpu/memory overhead.
// FREEBIE
We're overriding the default with null often enough that we should
just change the default.
Consequently, no more phantom blank conversations with oneself should
appear after receiving a group update. They were being added to the
inbox because they were incorrectly initialized with an active_at value.
Fixes#281
All the old event listeners and in-memory objects have perished with the
old background page. Also reopen the inbox if it was already open.
Fixes#289
// FREEBIE
Protocol and handling is all analogous to contact sync: Multiple
GroupDetails structs are packed into a single attachment blob and parsed
on our end. We don't display the synced groups in the conversation list
until a new message is sent to one of them.
// FREEBIE
Initializing a message receiver opens the socket and starts listening
right away rather than requiring a separate call to connect. The only
other publicly accessible method is to query the socket status.
// FREEBIE
Update protobuf definitions and refactor message receive and decrypt
codepath to support new protocol, including various flavors of sync
messages (sent messages, contacts, and groups).
Also cleans up background.js and lets libtextsecure internalize
textsecure.processDecrypted and ensure that it is called before handing
DataMessages off to the application.
The Envelope structure now has a generic content field and a
legacyMessage field for backwards compatibility. We'll send outgoing
messages as legacy messages, and sync messages as "content" while
continuing to support both legacy and non-legacy messages on the receive
side until old clients have a chance to transition.
If all the application windows are closed (and not merely hidden), the
background page will go inactive and there's nothing we can do to stop
it. However, we can ask chrome to trigger an alarm once per minute,
which will spin up the background page and check for new messages.
This will effectively keep us alive as long as chrome has open windows
or is running in the background, subject to chrome settings'

In a multi device world, it's possible to receive a receipt for a sync
message before the sync message actually arrives. In this case we need
to keep the receipt around and the process it when the message shows up.
Appify tabs, windows, browserAction
Port the extension.windows.focus function to new window api and
generalize its error handling in the case where the requested window
does not exist. An error will be passed to the callback.
Port extension.browserAction and rename it to the more generic
extension.onLaunched.
Use of the id option when opening a window ensures that attempting to
open a duplicate window merely focuses the existing window.
Finally, after registration, close the options window and open the
inbox.
Port extension.remove
Add window.storage to the background page, which loads all data from the
'items' store in indexeddb, caching them in memory for synchronous
access, then override textsecure storage to use that in memory store.
Encapsulate the websocket resources and socket setup process in a
friendly OO class. The MessageReceiver constructor expects an instance
of EventTarget on which to fire message events asynchronously. The
provider of the EventTarget can then add/remove listeners as desired.
