When we re-register, our deviceId might change, which makes our sessions
are no longer valid since the recipient will see us as a new device.
Fixes#388
Fix a bad loop scope bug in getKeysForNumber by using forEach.
Refactor the initial process of establishing key material for devices
that do not have open sessions.
// FREEBIE
For non text messages (ex: media messages and group updates), the
lastMessage field was being populated with empty string, resulting in an
empty message preview in the conversation list. Instead, display 'Media
message' or 'Updated the group', etc...
// FREEBIE
These functions accept an array buffer and extract an AES and MAC key
from it without verifying it has the appropriate length. Ciphertext
messages are similarly dissected. The slice function does not raise an
error on out of bounds accesses but instead returns an empty or
partially-filled array. Empty or short arrays will be passed through to
the window.crypto.subtle API, where they will raise an error. We should
not rely on the Web Crypto API to validate key lengths or for MAC checks
to fail. Instead, validate the lengths of given parameters before
extracting their components.
// FREEBIE
This may increase processing latency a bit, particularly with large
attachments, but will ensure that messages are dispatched in the order
they are received.
It would be nice to enforce ordering on only the dispatch step, so that
we could, for example, decrypt the next websocket message while waiting
for an attachment to download, but that will require a more complicated
refactor. Will stick with the quick fix for now and revisit later.
Fixes#342
// FREEBIE
It's rare that we get in a state where we have a device record without a
session, but we should handle errors gracefully in that case. Catch them
and register them, except for identity key errors which are registered
in handleResult.
// FREEBIE
fixup error handling // FREEBIE
This function dynamically declares a bunch of functions which bind to
its input arguments. Instead, use a new prototypal class to define
these functions within the context of a particular message.
// FREEBIE
Add a pendingMessages object to MessageSender. This object holds
one promise per recipient number. We init this promise with
Promise.resolve(), and chain on promises for message sending, replacing
the previous promise with the newly chained promise each time. If the
current promise resolves and finds that it is still the last promise
in the chain, it removes itself.
Websocket resources should have their keepalive timers reset whenever a
message comes in. This is a nicety that slightly reduces the amount of
traffic we send when actively messaging.
Previously this was handled by MessageReceiver, but it's a bit cleaner
to just have the WebsocketResource add an extra 'message' event handler.
// FREEBIE
Bind the sub-view to some data when we initialize it, rather than
passing it in on render. That means the image view click handler will
only ever open the blob we bound it to, even if its src attr changes for
some reason, which should never happen, but if it does, it's nice to
guard against opening arbitrary urls found in the dom.
// FREEBIE
Images that are attached to messages, either sent or received
can be opened in a new tab by clicking on them.
The previous approach that used Anchors to open the image
attachmets failed in various systems because:
- Chrome on Windows recognised "blob" as protocol and tried
to find an app for it
- Chromium on Ubuntu didn't open a new window to load the URL
The new approach adds a "click" listener to the IMG element and
opens the link using window.open (which seems to be working globaly).
Resolves: #252
In rare cases, a race between delivery receipts and outgoing message
requests can cause the sent flag to be reversed. Fix by marking messages
sent at the same time they are marked delivered.
// FREEBIE
Per WhisperSystems/TextSecure@8a1428e, bump GIF limit to 5MB, and
audio/video limit to 100MB. Update toast to notify in correct
human-readable units. The only kB size limit is for images, and will
trigger only if after scaling up to 4 times, the rescaled image did not
come in under the size limit without unacceptable quality loss.
Closes#354
Using the search field produces a filtered view of all contacts and
groups containing the input. To make this fast and scalable, add an
index on a 'tokens' array containing words from the conversation name
and different forms of phone number.
Closes#365
// FREEBIE
Split into separate encrypt and transmit functions. Let the encryption
function also handle all wire formatting (ie, jsonification and base64
encoding), which simplifes TextSecureServer.sendMessages, removes a
TODO, and lets us save fewer params to make network errors replayable.
// FREEBIE
The resend button should disappear once you've clicked it. This was not
happening because the message detail view held a cached copy of the old
message errors. Fix by re-reading the errors when we re-render.
// FREEBIE
This ensures that the containing promise is rejected without triggering
the side effects of an uncaught exception, such as causing the debugger
to pause.
// FREEBIE
Opening two message-detail views in two separate conversations would
disappear one of the conversations. Fixed by better encapsulating the
sub-views of a conversation.
// FREEBIE
Previously would fail to register keys by using the wrong username.
The username should be <number>.<deviceid> once we've confirmed our
account and received a deviceId from the server.
// FREEBIE
`tryMessageAgain` is the routine called when re-trying a message that
failed to decrypt due to an IncomingIdentityKeyError. This handling
needs to move to MessageReceiver because it depends on
`processDecrypted` to handle incoming message protos, which depends
on a server instance in order to download attachments.
// FREEBIE
textsecure.MessageSender takes server url and credentials and returns
a message sending interface configured for that server.
Used a wrapper function to insert a TextSecureServer instance into
sendmessage.js code at runtime. This will result in function duplication
between different MessageSender objects, pending further refactoring to
use prototypal inheritence.
// FREEBIE
Following the pattern from previous commit, let the server class accept
a url and login credentials from the caller. Then integrate into
MessageReceiver and AccountManager.
// FREEBIE
An exception to the previous commit, for incoming messages we should not
show a mysterious empty bubble. Instead there is some generic
non-technical error message.
// FREEBIE
Change how message errors are rendered. Errors associated with a number
will be shown under that number in the detail view rather than piling up
in the message bubble.
// FREEBIE
Fix inconsistency in error format, where we sometimes get an unexpected
Error object and sometimes get a wrapper object containing an Error.
Also start saving network errors.
// FREEBIE
Refactor outgoing message error handling to use the same success and
error handlers. This creates a somewhat strange pattern, where we call
send and pass in the promise that resolves when sending is complete, but
there's enough variety in the libtextsecure syntax for different message
sending routines that it belongs at the conversation level and only the
post-processing stuff is really shared by all messages.
// FREEBIE
There is no in-window navigation in the chrome app environment, so nix
the first if-clause here. Also make it programmatically reloadable and
fix indentation.
// FREEBIE
1. This is nonstandard behavior, not supported by any other clients. It
may help sometimes but will also cause bugs (see 2)
2. iOS doesn't handle group updates with missing fields. all fields must
be populated, and libtextsecure doesn't have any knowledge of the group
name or avatar, so these updates will clobber group state on iOS.
// FREEBIE
This one's been around since forever, but only manifests when someone
leaves the group and comes back. In that case we fail to reinit their
numberRegistrationId object, which causes a npe when we try to send
send them group messages.
Affected parties must ask their fickle friends to leave/join again.
// FREEBIE
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
The conversation's contactCollection only contains references to the
current membership, and will not provide contact info for people who
have left the group, causing their messages to render without numbers or
avatars.
// FREEBIE
When confirming the creation of a one on one conversation with a new
contact, the first click would do nothing but the second click would
work. Now the first click works.
Fix by only reject new conversation creation if not saved.
// FREEBIE
Fixes auto archive when deleting all messages, and auto unarchive when
sending a new message. Previously, the convo would not reappear in the
inbox after deleting all messages.
// 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
This listener is doing way more work than necessary to update the dom by
removing all the list items and re-creating them. This also causes the
bug where selected state is cleared when new messages arrive, not to
mention binding new event listeners without unbinding the old ones.
Fix by simply promoting an element to the top of the list when it's
active_at value changes, rather than re-rendering the whole list. This
could backfire if the value gets changed to an earlier timestamp but for
now we assume that won't happen.
// FREEBIE
The chrome.notifications api renders iconUrls at full bleed, as opposed
to the Web Notifications api, which adds padding. This was causing our
identicons to look a bit over stretched.
Fixed by rendering them a bit larger and with some padding.
// FREEBIE
Only allow one notification at a time. Use a basic notification for
normal messages, and image notification for image messages, and a list
notification when there are multiple unread messages.
// FREEBIE
Forgot to bind the socket event handler, and the then() handler should
come before the catch() handler or else it will execute every time the
catch handler executes.
// FREEBIE
Always test connectivity with an http request after a websocket closes,
regardless of what code/error it closed with. If that request succeeds,
automatically reconnect the socket.
// FREEBIE
Create a new collection type for the inbox which listens to events on
the main conversation cache. Also don't reload conversation info from
the database as often or when unnecessary.
Fixes#345
// FREEBIE
There's no need to use a custom collection type here since we don't use
any of the ConversationCollection methods. This helps prevent the
introduction of duplicate models for the same chat.
// FREEBIE
The delivery receipt handler should only update messages, so rather than
reloading the conversation and its contacts, only reload the messages.
// FREEBIE
Makes the groupupdate and recipient input fields stick to the top,
restyles the typeahead as a floating dropdown list of suggestions
rather than a full width component, fixes group avatar thumbnail
rendering.
// FREEBIE
Used by member list view. Refactored some templates for shared markup.
Fixes strange behavior where members in the list were hoverable and
selectable.
// FREEBIE
Establishes basic functionality for viewing conversations in two column
mode, including message area and message list resizing, and maintaining
scroll position.
Various subviews need to be retooled but are more or less still
functional, i.e., new message, message detail, key verification, etc...
Start by requesting keys for only the master device, then handle 410 as
needed. Single-device users are the more common case and this strategy
lets us avoid requesting/expending one of our own device keys when
establishing a session with sibling devices.
// FREEBIE
After setting a new identity key as trusted, we retry decryption on all
pending conflicts for that contact. If their identity changed twice in a
row, we can still get a conflict the second time, and should handle it
appropriately.
When resolving conflicts, we should not only discard the old key, but
set the new trusted key to the one the user has verified. Previously, we
would end up trusting the first-seen new key, which may not be the one
the user verified.
// FREEBIE
Related with #278. Redone to include keeping scroll at the bottom when resizing the window, as suggested in #305, and to better fit the current code structure.
This new endpoint should always issue a response to a provisioning
socket so if we don't receive one we should assume the connection has
been lost.
Closes#318
By default, automatically disconnect if no response. This is preferable
because we can sometimes lose connectivity without receiving a close
event from the socket, but it's also possible that the endpoint may not
support responses.
// FREEBIE
saveKeysToDeviceObject is the detector of outgoing identity key errors.
Catch these key errors closer to the source by pulling the
getKeysForNumber into the context of sendMessageToDevices, which lets
it access registerError and the message protobuf.
Previously identity key errors would be uncaught if all existing
sessions with a recipient were closed/deleted, since we would
preemptively fetch the new identity key. The old error handling only
kicked in after a 409/410 response from the server when posting a
message encrypted for a stale session.
