* Show and enforce the terminated state of a group
A group admin can permanently terminate a group. Afterwards the group is
read-only for everyone, not even an admin can send messages or start calls;
members keep access to the existing history. Other clients silently drop
messages sent to a terminated group.
Read the DecryptedGroup.terminated flag through GroupInfo.isTerminated() and:
- surface it in listGroups (json and plain text) and as the DBus IsTerminated
group property
- refuse to send to a terminated group locally (messages, reactions, typing and
group stories) rather than send one that other clients ignore
- drop incoming messages addressed to a terminated group
* Add terminateGroup command to terminate a group for everyone
Let a group admin permanently terminate a GroupV2 group via the
TerminateGroupAction (Groups.proto field 28, change epoch 7) the pinned library
already exposes as GroupsV2Operations.createTerminateGroup().
- GroupV2Helper.terminateGroup builds and commits the change
- GroupHelper.terminateGroup resolves/refreshes the group (v2 only), sends the
update to members and syncs storage, with the same conflict-retry as
updateGroup
- exposed through Manager.terminateGroup, the terminateGroup CLI/JSON-RPC command
and the DBus Group.terminateGroup method
