This patch introduces a helper class for SQfLite encryption related operations.
Most matrix clients will encrypt their sqlite database at rest. Since
this is a quite fragmented task using the Flutter sqlite ecosystem, this
helper aims to simplify some more complex operations.
It in particular helps with the following tasks :
- loading the correct shared objects / dynamic libraries for sqlcipher
- check whether a database is encrypted
- migrate an unencrypted SQLite database to SQLCipher
- apply the cipher to a database while opening it and ensure it loads
This code is not exactly matrix related, though presumably any matrix
client will use parts of it.
Possible regressions :
- `package:sqlite3` became a direct dependency. As of now it already was a
transitive dependency of the SDK itself.

This refactors the transaction
workaround with
"zone transactions" and
abstracts them in a mixin. Then
it just uses this mixin in the
HiveDatabase and the
sqflite_box and also applies
them on indexedDB to
fix transactions on web.
This creates a set before
requesting users from the
database. This prevents
doing the same check for
the same user multiple
times and also prevents
concurrent modifications
of the event list.
This changes the behavior
when client init fails. It
no longer calls logout and does
only clear local data while
returning all available
information in a new
exception type so that the
SDK consumer can decide
to logout or try again to init
with these information. This
should make it much more rare
that users loose their sessions.
This creates the timeline object
earlier in the Room.getTimeline() method.
This results to that the
Timeline object already starts
to listen on the event stream
while the getTimeline() method
requests users from the database
and tries to decrypt room
events. I assume that this
causes the problem that
on timeline creation new
events get lost because they
come in, while getTimeline() is
not yet completed but the
onEvent stream is not yet
connected at the same time.
This fixes the response
timeout for the initial
sync and sets it to 2
minutes instead of 10
seconds. This should increase
the speed for the initial
sync especially for large
accounts. This change
also adds some
documentation in the
code about what
timeout does what.
This refactors three methods
regarding powerlevels. It
makes them a little bit more
readable and removes
unnecessary checks. it
also changes the canSendDefaultMessage
method in a way that it also
checks the events map in the
powerlevels so that it returns
true if message events are
overwritten there. It also
improves the dart docs and
explains in more detail what it
does.
dynamic.copy returned a type
error so I reverted the previous
change of the copyMap
method to an extension. Also
I found out that we have used
two copyMap methods in the
SDK which did exactly the same.
I deleted the old one and
changed the tests.
Unfortunately we need to copy
all maps. I took the opportunity
and abstracted the copy map
method to utils. I kept the
copyMap method as a
reference in HiveCollections
database to not require a
huge refactoring there as we
are going to ditch it anyway.
