Errors when generating a DH secret where silently ignored, resulting in
invalid key material being used.
This commit fixes the issue by upgrading the double ratchet library
and implementing the updated interface, which uses now slices instead of fixed bytes keys.
Currently there seem to be a bug with publishing the contact-code, and
each attempt result in the error `database is closed` (non-thread safe?). As discussed
previously we probably don't need to have fs persistence, so just
changing this to have it in memory.
This commit does a few things:
1) Add replies to messages, which are calculated at query time using a
join
2) Add a BlockContact api call that takes care of deleting messages from
a user, deleting the chat, and re-compute the denormalized values. As it
needs to run in a transaction, the method that it relies on take a
transaction as an optional parameter.
3) Change ID scheme for chats/contacts so that it's consistent across
messages/contacts
This is not compatible as I have modified a migration, but it's not a
problem as data compatibility can be broken
The signature of the `Raw` methods has been changed so that they return
the application messageID.
Clients will keep track of this ID and receive a notification through
the envelopesMonitor of the state of the envelopes (sent/expired).
Envelopes monitor is passed this ID as well.
We use an array of IDs as datasync messages might be batched.
Adds to api calls, Contacts() not paginated and SaveContact()
DeviceInfo and SystemTags have been stored as a blob to simplify
querying, although at some point we might want to query system tags (for
example to fetch all the blocked/added by us/added by them contacts),
but not a use case for now.
This commits adds two API calls:
SaveChat
GetChats
The first one behaves like an upsert.
The second takes two parameters, from, to and returns chats in reverse
order by timestamp.
Members and MembershipUpdates have been stored as blob of data to
simplify the querying (we never query them separately).
