Classic Calendar

[v1.6.0] (2026-07-04)

New Features

• Officer "Clear All" for world buffs (guild-wide start-fresh). An officer-only button in the World Buff window (and /calwbclear guild) wipes all world-buff data for the whole guild after a confirmation prompt. Implemented as a synced wipe epoch (WBWipeAt): the timestamp propagates like a setting (LWW), every member clears entries at/before it, and pre-wipe entries are rejected on sync (and skipped by migration) so cleared data can't resurrect from an offline peer. Location: WorldBuffDB.lua, WorldBuffSync.lua, WorldBuff.lua.
• Sortable columns in the World Buff window. Click a column header (Player Name, Main Name, Date Received, Dropped) to sort by it; click again to reverse direction. The active column shows a sort-direction arrow (Interface\Calendar\MoreArrow — the same icon Blizzard's calendar and FastGuildInvite use), and each header has a hover tooltip. Headers are fixed above the scroll area rather than scrolling with the rows. Location: WorldBuff.lua.

Changed

• Rebuilt world buff sync on the DeltaSync-1.0 library stack. Replaced the bespoke hash/session/delta protocol (WorldBuffHash.lua, WorldBuffDelta.lua, WorldBuffSession.lua, the old WorldBuffSync.lua, and the dead DataSync.lua) with a thin DeltaSync bridge routed through AceCommQueue-1.0 (throttled sends) and LibGuildRoster-1.0 (identity/trust). New hard dependencies: DeltaSync, AceCommQueue-1.0, GuildRoster.
  • Each of the 4 buff tables plus a guild-settings record is one DeltaSync "item" (wb:rend|hakkar|onyxia|nefarian, wb:settings); entries reconcile per-entry via last-writer-wins on lastModified. Uses the multi-host DS:NewHost API (DeltaSync MINOR 15+) under an isolated AceAddon shell (ClassicCalendarSync) so it can't clobber other DeltaSync consumers on the same client.
• World buff storage is now account-wide, keyed by guild (ClassicCalendarWBDB), replacing the four per-character positional arrays. Entries are stored as [normalizedPlayerKey] = entry maps (LibGuildRoster-normalized keys) instead of index arrays, eliminating duplicate rows and index/name drift. A one-time migration folds each character's legacy WorldBuff*Data into the guild store on first login. Location: WorldBuffDB.lua.
• Ship explicit per-flavor TOCs instead of packager-generated multi-version. ClassicCalendar.toc is now Classic Era only (## Interface: 11508); a new ClassicCalendar_BCC.toc carries BCC (## Interface: 20505). .pkgmeta enable-toc-creation is now no. Multi-## Interface-* single TOCs proved unreliable to load on live installs; matches the per-flavor convention used by GuildRoster / FastGuildInvite. Both TOCs must keep the same file load list.

Bug Fixes

• Fixed dropped status never propagating. The field was written as the string "Yes"/"No" but hashed as tostring(entry.dropped == true), so it always hashed as "false" — toggling it never changed the sync hash. dropped is now a canonical boolean everywhere. Location: WorldBuff.lua, WorldBuffDB.lua.
• Fixed guild event creation being blocked while the GM is offline. The RestrictGuildEventsToOfficers gate now fails open — members can create guild events unless an officer has explicitly enabled the restriction. The setting rides the DeltaSync relay, so any guildmate holding it can serve it (previously only the setter could answer a request). Location: ClassicCalendar.lua, WorldBuff.lua.
• Fixed unthrottled comms. World buff messages now route through AceCommQueue-1.0, preventing ChatThrottleLib chunk interleaving / CRC corruption under guild load.

Hardening

• Deterministic convergence tie-break. Version vectors now carry a content checksum alongside the timestamp, so two edits to the same entry (or setting) in the same second resolve to the same winner on every peer instead of offering forever. The guild-settings hash also excludes setBy (not reconciled by the LWW merge) to avoid the same no-op-resync trap. Location: WorldBuffSync.lua, WorldBuffDB.lua.
• Anti-grief wipe epoch. A wipe epoch more than a day in the future is rejected, so a modified client can't clear everyone's data and block new entries indefinitely. Migration and the receive path both honor the epoch, so cleared data can't resurrect from an offline peer. Location: WorldBuffDB.lua.
• World Buff window: frame pooling, key case-folding, roster-load refresh. Table rows are pooled/reused instead of leaking a frame per row on every render/sort/sync; normalized player keys are case-folded so bob/Bob dedupe to one entry; the window refreshes once the guild roster loads so it isn't stuck empty when opened at login. Location: WorldBuff.lua, WorldBuffDB.lua, WorldBuffSync.lua.
• Guildless edits are rejected with a message instead of silently dropped (world buffs are guild-scoped). Location: WorldBuff.lua.

Removed

• DataSync.lua, WorldBuffHash.lua, WorldBuffDelta.lua, WorldBuffSession.lua, and the bespoke WorldBuffSync.lua protocol. The XOR-obfuscated CC-SET guild-settings channel is retired in favour of the wb:settings DeltaSync item.

Bug Fixes

• Fixed invite list #, Rank, and Level sort buttons firing both their own handler and the inherited template handler on each click — added inherit="false" to <OnClick> in ClassicCalendarTemplates.xml
• Fixed custom sort columns cycling through a redundant third "clear" state — now toggles between ascending and descending only, matching native sort button behavior
