/!\ new optional dependency: CairoSVG (with installed `[SVG]` extra)
- new `convert` method in `tools.image` to save an image in an other format, with support
for SVG (when CairoSVG is available)
- new `imageConvert` method is available for frontends
/!\ huge commit
Avatar logic has been reworked around the IDENTITY plugin: plugins able to handle avatar
or other identity related metadata (like nicknames) register to IDENTITY plugin in the
same way as for other features like download/upload. Once registered, IDENTITY plugin will
call them when suitable in order of priority, and handle caching.
Methods to manage those metadata from frontend now use serialised data.
For now `avatar` and `nicknames` are handled:
- `avatar` is now a dict with `path` + metadata like `media_type`, instead of just a string
path
- `nicknames` is now a list of nicknames in order of priority. This list is never empty,
and `nicknames[0]` should be the preferred nickname to use by frontends in most cases.
In addition to contact specified nicknames, user set nickname (the one set in roster) is
used in priority when available.
Among the side changes done with this commit, there are:
- a new `contactGet` bridge method to get roster metadata for a single contact
- SatPresenceProtocol.send returns a Deferred to check when it has actually been sent
- memory's methods to handle entities data now use `client` as first argument
- metadata filter can be specified with `getIdentity`
- `getAvatar` and `setAvatar` are now part of the IDENTITY plugin instead of XEP-0054 (and
there signature has changed)
- `isRoom` and `getBareOrFull` are now part of XEP-0045 plugin
- jp avatar/get command uses `xdg-open` first when available for `--show` flag
- `--no-cache` has been added to jp avatar/get and identity/get
- jp identity/set has been simplified, explicit options (`--nickname` only for now) are
used instead of `--field`. `--field` may come back in the future if necessary for extra
data.
- QuickContactList `SetContact` now handle None as a value, and doesn't use it to delete the
metadata anymore
- improved cache handling for `metadata` and `nicknames` in quick frontend
- new `default` argument in QuickContactList `getCache`
- `items` was returning the dict with all values, it now returns a Deferred with actual dict items()
- `all` new method does return the dict with all values (in a Deferred)
- `adel` has been added to LazyPersistentBinaryDict
media type is guessed first from filename, then if it's not enough, the file is opened to
try to guess type. If it still can be determined, None is returned.
typeCheck() is not automatically called on reception by Wokkel, as a result extensions
fields values may be strings instead of the field type. TypeCheck is now explicitly
called in memory.disco to avoid that. It is not called immediately on reception as the
string value is needed to calculate the capability hash
- profile is now always removed from profiles_connecting
- an exception is raised if client already exists only if client is connected. Otherwise,
it's deleted (this allow to keep session open to e.g. modify settings in case of failure
during connection)
- the workflow done with /omemo_reset is now using the right methods
(encryptRatchetForwardingMessage and decryptRatchetForwardingMessage)
- fixed type error with device when calling python-omemo methods: a mix of str and int
was leading to two caches being created, and random bugs
OMEMO trust policy can now be specified. For now there are 2 policies:
- `manual`: each new device fingerprint must be explicitly trusted or not before the
device can be used, and the message sent
- `BTBV` (Blind Trust Before Verification): each new device fingerprint is automically
trusted, until user manually trust or not a device, in which case the behaviour becomes
the same as for `manual` for the entity. When using the Trust UI, user can put the
entity back to blind trust if they wish.
A message is send as feedback to user when a new device is/must be trusted, trying to
explain clearly what's happening to the user.
Devices which have been automically trusted are marked, so user can know which ones may
cause security issue.
If peer sends encrypted message and we have no encryption activated, we automatically
start encryption to avoid sending plain text message when answering.
markAsEncrypted now needs the encryption algorithm namespace as mandatory argument.
- `encrypted` flag is now put directly in extra, so that there is nothing to change when
sending the message to bridge for frontends to be aware of it.
- this flag is now also set when markAsEncrypted is used, so frontend can display
appropriate indicator to show that outgoing message is encrypted or not.
post_xml_treatments was incorrectly added to workflow using chainDeferred (which only
add the callback, so post_xml_treatments own callbacks were not waited). As a result,
plugins callback could not be waited as expected before a message was sent.
This patch fixes it by not using chainDeferred anymore.
attachment handling has been simplified, and now use a "register" method similar as the
ones used for download or upload.
A default method (for unencrypted messages) will try a simple upload and will copy the
links to body.
AESGCM plugin has been adapted to be used for encrypted files. If more than one file is
sent with AESGCM plugin, they will be split in several messages as current de-facto
standard (OMEMO media sharing) doesn't support several files per message.
