- all content actions are now handled
- XEP-0167: the new contents of an offered SDP are added with a single content-add, the
contents sharing a single transport are bundled (XEP-0338)
- XEP-0167: the generated SDP declares the BUNDLE group of its own contents
- XEP-0176: one transport-info IQ per content. ICE data are keyed by content names.
- fix session-level ICE attributes and fingerprint
This is a series of changes necessary to prepare the implementation of remote control
feature:
- XEP-0166: add a `priority` attribute to `ApplicationData`: this is needed when several
applications are working in a same session, to know which one must be handled first.
Will be used to make Remote Control have precedence over Call content.
- XEP-0166: `_call_plugins` is now async and is not used with `DeferredList` anymore: the
benefit to have methods called in parallels is very low, and it cause a lot of trouble
as we can't predict order. Methods are now called sequentially so workflow can be
predicted.
- XEP-0167: fix `senders` XMPP attribute <=> SDP mapping
- XEP-0234: preflight acceptance key is now `pre-accepted` instead of `file-accepted`, so
the same key can be used with other jingle applications.
- XEP-0167, XEP-0343: move some method to XEP-0167
- XEP-0353: use new `priority` feature to call preflight methods of applications according
to it.
- frontend (webrtc): refactor the sources/sink handling with a more flexible mechanism
based on Pydantic models. It is now possible to have has many Data Channel as necessary,
to have them in addition to A/V streams, to specify manually GStreamer sources and
sinks, etc.
- frontend (webrtc): rework of the pipeline to reduce latency.
- frontend: new `portal_desktop` method. Screenshare portal handling has been moved there,
and RemoteDesktop portal has been added.
- frontend (webrtc): fix `extract_ufrag_pwd` method.

Implement XEP-0343: Signaling WebRTC Data Channels in Jingle. The current version of the
XEP (0.3.1) has no implementation and contains some flaws. After discussing this on xsf@,
Daniel (from Conversations) mentioned that they had a sprint with Larma (from Dino) to
work on another version and provided me with this link:
https://gist.github.com/iNPUTmice/6c56f3e948cca517c5fb129016d99e74 . I have used it for my
implementation.
This implementation reuses work done on Jingle A/V call (notably XEP-0176 and XEP-0167
plugins), with adaptations. When used, XEP-0234 will not handle the file itself as it
normally does. This is because WebRTC has several implementations (browser for web
interface, GStreamer for others), and file/data must be handled directly by the frontend.
This is particularly important for web frontends, as the file is not sent from the backend
but from the end-user's browser device.
Among the changes, there are:
- XEP-0343 implementation.
- `file_send` bridge method now use serialised dict as output.
- New `BaseTransportHandler.is_usable` method which get content data and returns a boolean
(default to `True`) to tell if this transport can actually be used in this context (when
we are initiator). Used in webRTC case to see if call data are available.
- Support of `application` media type, and everything necessary to handle data channels.
- Better confirmation message, with file name, size and description when available.
- When file is accepted in preflight, it is specified in following `action_new` signal for
actual file transfer. This way, frontend can avoid the display or 2 confirmation
messages.
- XEP-0166: when not specified, default `content` name is now its index number instead of
a UUID. This follows the behaviour of browsers.
- XEP-0353: better handling of events such as call taken by another device.
- various other updates.
rel 441
- add a `jingle_preflight_info` method in the Jingle Application model to handle this kind
of information
- XEP-0353 is calling `jingle_preflight_info` when a `ringing` message is received
- XEP-0167 use this information to send a `ringing` info to frontends
- XEP-0166: add `jingle_preflight` and `jingle_preflight_cancel` methods to prepare a
jingle session, principally used by XEP-0353 to create and cancel a session
- XEP-0167: preflight methods implementation, workflow split in more methods/signals to
handle UI and call events (e.g.: retract or reject a call)
- XEP-0234: implementation of preflight methods as they are now mandatory
- XEP-0353: handle various events using the new preflight methods
