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.
- async coroutine can now be used for text commands (in addition to Deferred and regular
callbacks)
- isidentifier is now used to detect a command, allowing to use "_" in command names
- if message starts with a single `/`, it is never sent (previously it could be sent is
some corner cases)
- don't use OrderedDict anymore as dict now keep insertion order by default
- max_items = 1 is requested with publish-options when publishing the bundle or the
devices list. If the constraint is failed, a warning will be shown, and the publication
will be done without this option
- fixed return values when devices list is badly formed
- sendItems is now an "async" coroutine, and sendItem use it instead of duplicating
publication logic
- policy to use when a precondition is not met (with publish-options) can now be
specified, for now it's either raise the exception (default policy), or try to publish
without the options
- constants have been added to handle "extra" keys
isConnected was returning True as soon as transport was connected. It is now returning
True only if full connection is done (i.e. transport is connected + all plugins have been
initialised).
"path" refers to a local path of a file, we don't want to store it in database as the file
may be in a temporary location, or even be a temporary file. So once the file has been
uploaded, we remove it.
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).
