Apply Patreon supporter ranks from ProvinceSystem - #29
Merged
Merged
Conversation
The third-party PatreonPlugin stops working when Patreon retires API v1 on 7 October, and it never counted gifted memberships. ProvinceSystem now decides each supporter's tier; this plugin applies it. One server, set with patreon.apply-ranks, polls the rank outbox and adds or removes the noble, gilded and ascended LuckPerms groups, then pushes the update to the other servers. It only removes permanent global nodes for those three groups, so staff grants and the legacy group are left alone. /patreon shows a player's supporter status and a link to connect.

Merge Risk: ⚪ Minimal · up to The Patreon features are optional, and the supplied evidence shows rank updates are checked before acknowledgement and failed reconciliation remains retryable. No concrete merge-blocking risk is identified. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Rank synchronization is disabled by default and limits changes to configured supporter groups. Once enabled, however, partial failures can leave rank revocations stale across servers or allow older changes to be replayed after newer ones. Backend authorization and recovery guarantees still need confirmation. Retained concerns

- Around line 129-144: Update hasGlobal to skip inheritance nodes with any
expiry by checking hasExpiry() instead of only hasExpired(). Count only
permanent, context-free matching grants.
- Around line 73-77: In setGroups, avoid unconditional saves and pushUpdate
calls for unchanged members by tracking whether mutate changed the data. Save
when data changed, the user was already loaded, or the UUID has a pending failed
save; push updates only after a successful save of changed or pending-retry
data. Preserve retry state after a failed save so an equivalent later request
persists the in-memory change.

- Around line 49-62: Update the httpUrl method to require a non-null URI host in
addition to an HTTP or HTTPS scheme before accepting a URL. Keep the existing
invalid-URI handling unchanged.

Reconcile no longer saves or broadcasts an update for a player whose nodes did not change, and a save that failed is retried on the next request. Only a permanent, context-free node counts as the granted rank, so a temporary node no longer hides a missing permanent one. Clickable links now require a host. A Patreon store test left the default locale set to Turkish, which broke MockBukkit's enum lookup in tests that ran after it on CI.

A removal LuckPerms refused was counted as success, so the outbox row was acknowledged while the group was still present. The store now checks that every requested removal is gone and reports failure otherwise, so the change is retried. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Why
Supporter ranks are granted today by the third-party PatreonPlugin on the lobby. It calls Patreon API v1, which Patreon retires on 7 October, and it has never counted gifted memberships. ProvinceSystem is taking over as the one place that talks to Patreon and decides each supporter's tier. TFMCWeb applies the in-game half.
What changes
patreon.apply-ranks: true, the plugin pollsGET /patreon/plugin/rank-changes, adds and removes thenoble,gildedandascendedLuckPerms groups through the LuckPerms API (offline players included), and acknowledges only the changes that saved. Everyreconcile-minutesit corrects drift againstGET /patreon/plugin/roster./patreonon every server shows a player's supporter status, with a clickable link to connect when they are not linked./patreon unlinkdisconnects.What it will not touch
Only permanent, global inheritance nodes for the three mapped groups are ever removed. Temporary or context-specific nodes, the
legacygroup, and any group outside the mapping are left alone. Players who are not in the backend roster are never modified. The stored primary group is never written.Config
Off by default, so merging changes nothing until it is enabled.
