From b5b4f188a39fc96c4d32e67151e067b1add6dcfc Mon Sep 17 00:00:00 2001 From: Christophe Besson Date: Fri, 28 Aug 2026 02:51:00 +0200 Subject: feat(hub): let a hub admin disable public groups instance-wide MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A new General tab in Administration carries one switch, allow_public_groups, stored in a hub_settings key/value table (runtime-editable, unlike hub.toml). Default is on; an absent row means on, so an upgrade changes nothing. Enforcement is server-side on every hub-mediated path, not just the SPA: - create_group refuses visibility=public (403), staff included - list_public_groups the directory returns nothing (local + federated) - join_group open-joining a public group is refused - group_online_nodes a non-member of a public group is handed no node - signaling.webrtc_offer drops the "node hosts an open group" fallback - federation.export_directory advertises nothing to peer hubs The switch is read live, so flipping it back restores every path. Existing members of a group that predates the switch keep their membership row and their access — this is plan A, not a purge. GET /v1/hub/info exposes the flag (unauthenticated) so the create-group form and the sidebar's "Public groups" link render correctly. Also in the admin Groups tab: a Revoke action beside Suspend. Suspend is the reversible hub flag; Revoke calls POST /v1/admin/revoke, which sets status=revoked and broadcasts a signed revocation every node enforces (denylist + dropped live sessions). It is confirm-guarded and names the group. And a message fix the revoke work surfaced: group_online_nodes, join_group and webrtc_offer answered "Group is suspended" for any non-active status. They now report the real state, so a member of a revoked group is told "Group is revoked" rather than something reversible-sounding. Tests: test_public_groups_toggle.py (10) covers the switch end to end and the five enforcement paths; test_revocation.py gains the status-message assertion.
