/!\ this is a huge commit
/!\ starting from this commit, SàT is needs Python 3.6+
/!\ SàT maybe be instable or some feature may not work anymore, this will improve with time
This patch port backend, bridge and frontends to Python 3.
Roughly this has been done this way:
- 2to3 tools has been applied (with python 3.7)
- all references to python2 have been replaced with python3 (notably shebangs)
- fixed files not handled by 2to3 (notably the shell script)
- several manual fixes
- fixed issues reported by Python 3 that where not handled in Python 2
- replaced "async" with "async_" when needed (it's a reserved word from Python 3.7)
- replaced zope's "implements" with @implementer decorator
- temporary hack to handle data pickled in database, as str or bytes may be returned,
to be checked later
- fixed hash comparison for password
- removed some code which is not needed anymore with Python 3
- deactivated some code which needs to be checked (notably certificate validation)
- tested with jp, fixed reported issues until some basic commands worked
- ported Primitivus (after porting dependencies like urwid satext)
- more manual fixes
- RSM and MAM args arguments have been added to pubsub group, and activated when multiple items are possible
- /!\ --max-items (i.e. pubsub original max) short option has been change for -M, and -m is now used for RSM max
- pubsub/search -m option has been renamed -M for same reason as above
- pubsub/search -o option has been replaced by -k (for keep), to avoid conflict with order-by (and long version is now --node-max)
- encryption algorithm can now be requested when sending a message (using --encrypt option)
- new encryption commands to (de)activate encryption session, check available algorithms, or manage trust.
- Plugin has been updated to use last version of python-omemo (10.0.3).
- A temporary method remove all storage data if they are found, this method must be removed before 0.7 release (only people using dev version should have old omemo data in there storage).
- Trust management is not implemented, using new encryptionTrustUIGet method (an UI is also displayed when trust handling is needed before sending a message).
- omemo.DefaultOTPKPolicy is now used, instead of previous test policy of always deleting.
OMEMO e2e encryption is now functional for one2one conversations, including fingerprint management.
- hooks can now be set in stream onElement and send methods
- xmllog refactored to use new hooks
- client.isConnected now uses transport.connected method
- fixed reconnection, SàT will now try to reconnect indefinitely until it success, unresolvable failure happen (e.g. invalid certificate), or explicit disconnection is requested (or a plugin change this behaviour)
- new triggers: "stream_hooks", "disconnecting", "disconnected", and "xml_init" (replace "XML Initialized")
XMPP server certificate is now checked, and connection is refused (by default) if it's not valid.
Certificate check can be disabled in the new parameter "Configuration/check_certificate".
If certificate checking is disabled, a warning note is sent on every new connection.
Twisted and Wokkel are temporarly monkey patched in sat.core.tls_patches module, until modifications are merged upstream.
