if dest_path is not set, the file will be downloaded in cache. A new name will be
generated using a hash of the uri. If the file is already downloded in cache, it won't be
downloaded again (in this case returned progress_id is an empty string).
SàT was using 16 bytes IV when sending files withr AES-GCM, due to ChatSecure being only
compatible with that. Monal, an other iOS client is only compatible with 12 bytes IV, and
ChatSecure has fixed its code to also handle 12 bytes IV, so there is not reason anymore
to use 16 bytes, and SàT now uses 12 bytes.
Android doesn't have a "/etc/resolv.conf" that Twisted expect. As a result, SRV records
can't be checked correctly on connection.
To work around that, DNS servers used on Android are checked when necessary (on Android
plugin startup and on connectivity change), using some hacks, and Twisted is patched to
use them.
`PyCrypto` is unmaintained for years but was used in SàT for password hashing. This patch
fixes that by replacing `PyCrypto` by the reference `cryptography` module which is well
maintained.
The behaviour stays the same (except that previously async `hash`, `encrypt` and `decrypt`
methods are now synchronous, as they are quick and using a deferToThread may actually be
more resource intensive than using blocking methods).
It is planed to improve `memory.crypto` by using more up-to-date cryptography/hashing
algorithms in the future.
PyCrypto is no more a dependency of SàT
instead of calling plyer's generic notify, AndroidNotification is now inherited to add a
SàT specific behaviour: a "sat_action" dictionary is now attached, to indicate to the
frontend what to do when the notification is opened.
this method will be called by frontend to know which profile to connect automatically
(when the frontend has been closed and is reopened, this will avoid to have to go through
the profileManager again).
A new Connection/autoconnect_backend param can be set for a profile or component to be
started automatically with backend. This is specially useful for components, but can be
useful for client profile too (e.g. on Android we need to start profile with backend to
get notifications, this part will come with following commits).
The new Sqlite.getIndParamValues method allows to retrieve the same parameters for all
profiles.
namespaces and encryption plugins are only retrieved once backend is ready, else they may
not yet be available (can happen notably when the backend is start at the same time as the
frontend, e.g. on Android).
- new notification sound
- vibration and notification sound are now activated depending on ringer mode (normal,
vibrate or silent)
- notification sound/vibration can be configured in settings.
- encryption is now allowed for group chats
- when an encryption is requested for a MUC, real jids or all occupants are used to
encrypt the message
- a cache for plain text message sent to MUC is used, because for security reason we can't
encrypt message for our own device with OMEMO (that would prevent ratchet and break the
prefect forward secrecy). Thus, message sent in MUC are cached for 5 min, and the
decrypted version is used when found. We don't send immediately the plain text message
to frontends and history because we want to keep the same MUC behaviour as for plain
text, and receiving a message means that it was received and sent back by MUC service
- <origin-id> is used to identify messages sent by our device
- a feedback_jid is now use to use correct entity for feedback message in case of problem:
with a room we have to send feedback message to the room and not the the emitter
- encryptMessage now only accepts list in the renamed "entity_bare_jids" argument
room statuses are now sent with other metadata on bridge signals, and saved in Room
instance. They give useful data on the room, for instance they can be used to know if a
full jid is used in this room.
- publishing options (XEP-0060 §7.1.5) implementation.
- jp pubsub/set can specify publish-options using `-f` and `-F`
- doc has been updated to explain that
- psItemSend and psItemsSend now use serialisation for "extra"
- publish-options can be specified in extra['publish-options'] with those methods
The scheme is register with download meta plugin, and it is activated with HTTP Upload
(XEP-0363) when `encryption` is used in `options` with the value of C.ENC_AES_GCM.
This is also known as `OMEMO Media Sharing` even if this method is not directly linked to
OMEMO and can be used independently.
- use of async/await syntax
- fileUpload's options are now serialised, allowing non string values
- (XEP-0363) Slot is now a dataclass, so it can be modified by other plugins
- (XEP-0363) Moved SSL related code to the new tools.web module
- (XEP-0363) added `XEP-0363_upload_size` and `XEP-0363_upload` trigger points
- a Deferred is not used anymore for `progress_id`, the value is directly returned
- first code in backend to use async/await Python syntax \o/
- plugin with file upload
- URL schemes can be registered
- `http` and `https` schemes are handled by default
- python-omemo minimal version is now 0.11.0
- `undecided` devices are now handled, fixing the "accept all or none" issue: if a device
is `undecided`, the trust manager will be shown with the missing devices before sending
the message.
- `untrusted` devices are discarded
Some servers don't store permanently the whole history of MUC with MAM. As a result, an
"item-not-found" stanza error can be received when message id used as reference doesn't exist
anymore on the server.
When this case happens, the history is retrieved in the same way as for a newly joined room
(i.e. last 50 messages are requested).
