1) On the push side, this message is a flag in PushMessageContent.
Any secure message with that flag will terminate the current
sessin.
2) On the SMS side, there is an "end session" wire type and
the convention that a message with this wire type must be
secure and contain the string "TERMINATE."
1) In addition to the Recipient interface, there is now
RecipientDevice. A Recipient can have multiple corresponding
RecipientDevices. All addressing is done to a Recipient, but
crypto sessions and transport delivery are done to
RecipientDevice.
2) The Push transport handles the discovery and session setup
of additional Recipient devices.
3) Some internal rejiggering of Groups.
1) Move all the crypto classes from securesms.crypto.
2) Move all the crypto storage from securesms.database.keys
3) Replace the old imported BC code with spongycastle.
1) Added a new message status to MmsDatabase to
signify a pending MMS download which requires
APN settings.
2) Added a database method to query MMS messages
based on status.
3) Added login to SendReceiveService for processing
of MMS pending APN information.
4) Moved all APN/MMS settings into ApnPreferencesActivity
and transformed PromptApnActivity into a simple
informational activity.
5) Added logic to check for APN settings on send and
receive of all MMS (media, group, email) and direct
user to PromptApnActivity then ApnPreferencesActivity
if necessary.
6) Vocab/grammar adjustments.
1) Broke out the UI elements of the major Activites into stylable
attributes.
2) Created a 'light' and 'dark' theme for the newly stylable attrs.
3) Touched up some of the UI spacing.
4) Implemented dynamic theme switching support.
1) There is no longer a concept of "verified" or "unverified."
Only "what we saw last time" and "different from last time."
2) Let's eliminate "verify session," since we're all about
identity keys now.
3) Mark manually processed key exchanges as processed.
1) We now try to hand out cursors at a minimum. There has always been
a fairly clean insertion layer that handles encrypting message bodies,
but the process of decrypting message bodies has always been less than
ideal. Here we introduce a "Reader" interface that will decrypt message
bodies when appropriate and return objects that encapsulate record state.
No more MessageDisplayHelper. The MmsSmsDatabase interface is also more
sane.
2) We finally rid ourselves of the technical debt associated with TextSecure's
initial usage of the default SMS DB. In that world, we weren't able to use
anything other than the default "Inbox, Outbox, Sent" types to describe a
message, and had to overload the message content itself with a set of
local "prefixes" to describe what it was (encrypted, asymetric encrypted,
remote encrypted, a key exchange, procssed key exchange), and so on.
This includes a major schema update that transforms the "type" field into
a bitmask that describes everything that used to be encoded in a prefix,
and prefixes have been completely eliminated from the system.
No more Prefix.java
3) Refactoring of the MultipartMessageHandler code. It's less of a mess, and
hopefully more clear as to what's going on.
The next step is to remove what we can from SmsTransportDetails and genericize
that interface for a GCM equivalent.
1) Update the create, prompt, and change passphrase activities.
They are no longer dialog themed, and should look a little
less ugly.
2) Update the import DB activity to be less ugly and more robust.
3) Abstract all of the state handling stuff out of
ConversationListActivity. This is now handled by RoutingActivity,
which all launch intents move through.
1) Consolidate all of the KeyCachingService interaction into a single
mixin. Activities extend delegates which call through to the mixin.
2) Switch Activity increment/decrement triggers from onStop to onPause
in order to account for some screen locks that don't stop activities.
1) Refactor the master secret reset logic to properly interact with
services.
2) Add support for "BigText" and "Inbox" style notifications.
3) Decrypt message bodies when unlocked, display 'encrypted' when
locked.
1) Don't add a notification item to the notification bar if the thread the
message is for is active and visible.
2) Only sound the notification ringtone at 1/4th volume if the thread the
message is for is active and visible.
3) Auto-clear the notification in the notification bar when a thread becomes
visible from a screen-off situation.
4) Make notification updates asynchronous.
1) Change the MessageSender logic so that individual SMS messages
are encrypted whenever there is a secure session, unless the UI
explicitly specifies otherwise.
2) Change the MMS logic so that messages to a recipient with a
secure session are all sent individually, instead of including
those recipients into the batch plaintext message.
1) Fix up the whitespace tagging so that it's a little more strict.
2) Don't display whitespace tags that we add to our own messages.
3) Make the tag detection prompt a little more visually pleasing.
1) Change all instances which use concatenation to build strings
with variables in them to use string formatting instead.
2) Extract all string literals from layouts and menus into strings.xml
3) Extract all string literals from code into strings.xml
1) Move to Fragments for the list view.
2) Switch to CursorLoader from my jankey self-managed cursor.
3) Add session security logic to the ActionBar.
4) Fix colors to be less ugly.
