Merge pull request #1013 from matrix-org/ismail/logout
Add logout facilities to `client` and helpers to ffi for tracking the soft-logout issued by a server. Further more this adapts the `sync_with_callback` by adding a new `sync_with_result_callback` that hands the entire `Result` to the callback.
This patch removes the `decode_image` (default) feature for this
`matrix-sdk-qrcode` crate.
First reason is that `rqrr` panics for some particular QR codes, and
we don't want to panic.
Second reason is that it's not a feature that is used. For Element on
iOS and Android, it's very unlikely that every frame from the camera
will be sent to `matrix-sdk-qrcode` to see if it can be decoded. So
it's obvious that an external library is used to read the bytes from
the QR code, that are then sent to `matrix-sdk-qrcode`. For Element on
Web, it's basically the same argument.
This feature is actually used only in our tests to ensure the
generated QR code is valid, but it sometimes fails due to `rqrr`
(cf. First reason).
`AnyDecryptedOlmEvent::Custom` contains at least 440 bytes, while the
second-largest variant (`RoomKey`) contains at least 0 bytes. Let's
box `Custom` so that the size of `AnyDecryptedOlmEvent` stays low.
A room ID can no longer be invalid, it's just a string representing
either a `EventId` (we can validate that but…) or a `TransactionId`
(which is an opaque string, so it can be anything).
This patch updates `QrVerification::new_cross`, by passing a flow ID
as an owned `String` to `VerificationData`, thus removing a panic, and
allowing QR code verification to happen outside a room.
This patch updates `VerificationData` to receive a flow ID,
represented as an owned `String`, instead of an `OwnedEventId`. Why?
Because QR code verification can happen outside a room. In such
scenario, there is no event ID, but a transaction ID, unified behind
the `matrix_sdk_crypto::FlowId` enum. `VerificationData` doesn't
really care about that details. Proof is that `QrVerificationData`
receives an owned `String`, which is then casted into an
`OwnedEventId` to match this API properly; but at the top, it just
receives a string.
This patch brings also a little bit of clean up while editing code
around.
