Struct RefreshPinRepoV0

pub struct RefreshPinRepoV0 {
    pub pin: PinRepo,
    pub ban_member: Option<Digest>,
    pub flush_topics: Vec<(TopicId, Sig)>,
}

Request to refresh the Pinning of a previously pinned repo.

it can consist of updating the expose_outer, the list of ro_topics and/or rw_topics, and in case of a ban_member, the broker will effectively flush the topics locally after all local members except the banned one, have refreshed

Fields

pin: PinRepo

The new PinRepo info

ban_member: Option<Digest>

optional hashed member ID that should be banned

flush_topics: Vec<(TopicId, Sig)>

when banning, list of topics that are to be flushed (once all the local members have left, except the one to be banned) All the honest local members have to send this list in order for the banned one to be effectively banned for each Topic, a signature over the hashed UserId to ban, by the Topic private key. The banning process on the broker is meant to flush topics that would remain dangling if the malicious member would not unpin them after being removed from members of repo. The userId of banned user is revealed to the local broker where it was attached, which is a breach of privacy deemed acceptable as only a broker that already knew the userid will enforce it, and that broker might be interested to know that the offending user was banned from a repo, as only malicious users are banned. The broker might also discard this information, and just proceed with the flush without much ado. Of course, if the broker is controlled by the malicious user, it might not proceed with the ban/flush. But who cares. That broker will keep old data forever, but it is a malicious broker anyway.
