This change simplifies
updating the gossip timestamps
when we receive a message
because we only need to know
the keys received in Autocrypt-Gossip
header and which chat the message is
assigned to.
We no longer need to iterate
over the member list.
This is a preparation
for PGP contacts
and member lists that contain
key fingerprints rather than
email addresses.
This change also removes encryption preference
from Autocrypt-Gossip header.
It SHOULD NOT be gossiped
according to the Autocrypt specification
and we ignore encryption preference anyway
since 1.157.0.
test_gossip_optimization is removed
because it relied on a per-chat gossip_timestamp.
The state bob needs to maintain during a secure-join process when
exchanging messages used to be stored on the context. This means if
the process was killed this state was lost and the securejoin process
would fail. Moving this state into the database should help this.
This still only allows a single securejoin process at a time, this may
be relaxed in the future. For now any previous securejoin process
that was running is killed if a new one is started (this was already
the case).
This can remove some of the complexity around BobState handling: since
the state is in the database we can already make state interactions
transactional and correct. We no longer need the mutex around the
state handling. This means the BobStateHandle construct that was
handling the interactions between always having a valid state and
handling the mutex is no longer needed, resulting in some nice
simplifications.
Part of #2777.
Raw MIME messages may contain non-ASCII characters. Attempting to
store them as TEXT by using String::from_utf8_lossy results in
non-ASCII characters being replaced with Unicode U+FFFD "REPLACEMENT
CHARACTER" which is later incorrectly decoded when attempting to parse
`mime_headers` content into HTML.
Switches from rusqlite to sqlx to have a fully async based interface
to sqlite.
