This commit fixes a few issues with communities encryption:
Key distribution was disconnected from the community description, this created a case where the key would arrive after the community description and that would result in the client thinking that it was kicked.
To overcome this, we added a message that signals the user that is kicked. Also, we distribute the key with the community description so that there's no more issues with timing.
This is a bit expensive for large communities, and it will require some further optimizations.
Key distribution is now also connected to the request to join response, so there are no timing issues.
Fixes an issue with key distribution (race condition) where the community would be modified before being compared, resulting in a comparison of two identical communities, which would result in no key being distributed. This commit only partially address the issue.
* feat: introduce KickedPending state for community members
* feat: tests for ban/unban pending states
* fix: remove pending And banned members from public serialization
* feat: add check for banning and kicking privileged users
* fix: process only first event when obtaining PendingAndBannedMembers
* fix: review fixes
* fix: proper conditions for kicking and banning checks
* Fix: fix tests after rebase
This is a bigger change in how community membership requests are handled
among admins, token masters, owners, and control nodes.
Prior to this commit, all privileged users, also known as
`EventSenders`, were able to accept and reject community membership
requests and those changes would be applied by all users.
This commit changes this behaviour such that:
1. EventSenders can make a decision (accept, reject), but merely forward
their decision to the control node, which ultimately has to confirm
it
2. EventSenders are no longer removing or adding members to and from
communities
3. When an eventsender signaled a decision, the membership request will
enter a pending state (acceptedPending or rejectedPending)
4. Once a decision was made by one eventsender, no other eventsender can
override that decision
This implementation is covered with a bunch of tests:
- Ensure that decision made by event sender is shared with other event
senders
- `testAcceptMemberRequestToJoinResponseSharedWithOtherEventSenders()`
- `testRejectMemberRequestToJoinResponseSharedWithOtherEventSenders()`
- Ensure memebrship request stays pending, until control node has
confirmed decision by event senders
- `testAcceptMemberRequestToJoinNotConfirmedByControlNode()`
- `testRejectMemberRequestToJoinNotConfirmedByControlNode()`
- Ensure that decision made by event sender cannot be overriden by other
event senders
- `testEventSenderCannotOverrideRequestToJoinState()`
These test cases live in three test suites for different event sender
types respectively
- `OwnerWithoutCommunityKeyCommunityEventsSuite`
- `TokenMasterCommunityEventsSuite`
- `AdminCommunityEventsSuite`
In addition to the changes mentioned above, there's also a smaller
changes that ensures membership requests to *not* attached revealed wallet
addresses when the requests are sent to event senders (in addition to
control nodes).
Requests send to a control node will still include revealed addresses as
the control node needs them to verify token permissions.
This commit does not yet handle the case of event senders attempting to
kick and ban members.
Similar to accepting and rejecting membership requests, kicking and
banning need a new pending state. However, we don't track such state in
local databases yet so those two cases will be handled in future commit
to not have this commit grow larger.
This component decouples key distribution from the Messenger, enhancing
code maintainability, extensibility and testability.
It also alleviates the need to impact all methods potentially affecting
encryption keys.
Moreover, it allows key distribution inspection for integration tests.

chore:
- add CommunityEventsMessage
- refactor community_admin_event to accept a list of events and patch a CommunityDescription
- save/read community events into/from database
- publish and handle community events message
- fixed admin category tests
- rename AdminEvent to Events or CommunityEvents
