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.
* Session records are now opaque strings, so treat them that way:
- no more cross checking identity key and session records
- Move hasOpenSession to axolotl wrapper
- Remote registration ids must be fetched async'ly via protocol wrapper
* Implement async AxolotlStore using textsecure.storage
* Add some db stores and move prekeys and signed keys to indexeddb
* Add storage tests
* Rename identityKey storage key from libaxolotl25519KeyidentityKey to
simply identityKey, since it's no longer hardcoded in libaxolotl
* Rework registration and key-generation, keeping logic in libtextsecure
and rendering in options.js.
* Remove key_worker since workers are handled at the libaxolotl level
now
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.
Now with actual malloc/free implementations. Had to drop back to -O1
optimization because the ed25519 signature test broke with -O2. :(
Closes#153
The toolchain install and build process, for reference:
```
wget https://s3.amazonaws.com/mozilla-games/emscripten/releases/emsdk-portable.tar.gz
tar xvfz emsdk-portable.tar.gz
cd emsdk-portable
./emsdk update
./emsdk install latest
./emsdk activate latest
source ./emsdk_env.sh
cd ../TextSecure-Browser
grunt build
```
When first intalling, users will no longer be presented with the option
to register as a standalone client.
For developer convenience, the standalone form can still be found at
chrome-extension://.../register.html
Closes#159
Simplifies the grunt watch task for sass. Renames sass partials with
leading underscores. Flattens stylesheet directory. The only remaining
raw css file is options.css.
Move globally-relevant styles to _global. Shrink overall font size.
