Classic Calendar

[v1.6.4] (2026-07-19)

Bug Fixes

• Fixed a Lua error when opening the Create Event window after Blizzard's Classic client API update. CalendarCreateEventDescriptionContainer_OnLoad threw ScrollUtil.RegisterScrollBoxWithScrollBar expected a 1:1 pairing, but this ScrollBar is already registered with another ScrollBox (ClassicCalendar.lua:4409). Root cause was a latent duplicate-global-name bug that Blizzard's update exposed: two EventFrames were declared with the identical global name CalendarCreateEventDescriptionContainerScrollBar — one inside the view-event description container (ClassicCalendar.xml:664, a copy-paste typo) and the correct one inside the create-event container (ClassicCalendar.xml:1020). Both OnLoads resolved that single shared global: CalendarViewEventDescriptionContainer_OnLoad registered it to the view's ScrollingFont scrollbox, then CalendarCreateEventDescriptionContainer_OnLoad tried to bind the same scrollbar frame to the create editbox's scrollbox. The old ScrollUtil silently re-registered; the updated EnsureScrollBarRegistration now error()s on that 1:1 violation. Fix: renamed the view container's scrollbar to its own unique global CalendarViewEventDescriptionContainerScrollBar, pointed CalendarViewEventDescriptionContainer_OnLoad at the corrected name, and registered the new global in .luarc.json. Pure UI/XML change shared identically by Era and BCC — no per-flavor branching. Location: ClassicCalendar.xml, ClassicCalendar.lua, .luarc.json.

Build / Packaging

• Fixed the release zip shipping docs/ and wow-version-replication.ps1. The .pkgmeta ignore list used pattern forms the BigWigs packager doesn't honor: docs/ (a trailing slash makes the packager's directory auto-expansion produce docs//*, which matches nothing) and **/*.ps1 (the leading **/ requires a subdirectory, so it never matched the root-level .ps1). Both leaked into the packaged addon. Rewrote the ignore list to the forms the packager's case-glob matcher actually uses — bare directory name (docs, auto-expanded to docs/*) and root globs (*.ps1, *.bat) — verified against the packager's match_pattern logic. Also removed three dead entries (BUG_TRACKER.md, developer_log.md, FEATURE_TRACKER.md) that targeted the repo root but whose files live under docs/, so they're now covered by the docs exclusion. Packaging-only: no addon behavior changes; takes effect on the next release build. Location: .pkgmeta.

[v1.6.3] (2026-07-15)

Changed

• Bumped the BCC TOC's ## Interface: to 20506. ClassicCalendar_BCC.toc still declared 20505, which the current Burning Crusade Classic client flags as out-of-date (the addon is disabled unless "Load out of date AddOns" is checked). Only the BCC TOC changes — ClassicCalendar.toc stays at Era 11508, and the two TOCs' file load lists remain identical. Location: ClassicCalendar_BCC.toc.

---

[v1.6.2] (2026-07-13)

New Features

• Online/offline column in the event sign-up list. Each signed-up player now shows a presence dot next to their status — green when online, grey when offline, and hidden when the signup isn't a current guild member. Presence comes straight from LibGuildRoster (GR:GetMember(name).isOnline via a new CC_GRC_IsMemberOnline helper), so it costs no extra roster scan. The column header ("ON") is sortable like the other custom columns (online-first by default, click to reverse) via the existing CC_CustomSortButton path and a new online branch in ApplyCustomSort; it's wired into both the view and create/edit invite lists. The dot is anchored to the Status column's left edge so it tracks the right side on resize. Location: ClassicCalendarTemplates.xml, ClassicCalendar.lua, GuildRankConfirm.lua.

Bug Fixes

• Fixed ClassicCalendar.lua being executed twice on every load. ClassicCalendar.xml opened with <Script file="ClassicCalendar.lua"/> while ClassicCalendar.toc already loaded ClassicCalendar.lua (before GuildRankConfirm.lua, so the latter could hook it). The XML's <Script> re-ran the entire file when the XML loaded — after GuildRankConfirm.lua had installed its hooks — redefining every global function (CalendarFrame_ShowEventFrame, the create/edit frame handlers, etc.) to fresh copies with no hooks attached. It also duplicated every RegisterEvent, the LibDBIcon setup, the world-buff sync init, the 30-minute heartbeat ticker, and VersionCheck registration, and raced two copies of every saved-variable write. Removed the redundant <Script> line; the TOC remains the sole loader, preserving the lua→GuildRankConfirm→xml order. Location: ClassicCalendar.xml.
  • Concretely fixes the Rank Auto-Confirm control never appearing reliably. With the CalendarFrame_ShowEventFrame hook detached, UpdateConfigButtonVisibility (and thus the control's creation) never ran when an event frame opened. The control only ever showed when a CALENDAR_UPDATE_EVENT happened to fire with the frame open — hence "it was there ten minutes ago, then a guildmate logged on and it vanished." The reliable hook path now survives, so the control is created whenever a guild event's create/edit frame opens. (The control itself is also reworked into a dropdown menu — see Changed.)
• Fixed CalendarHelper initializing twice. CalendarHelper.lua contained a copy-pasted duplicate of its entire init tail — two CreateFrame frames each registered for ADDON_LOADED/PLAYER_LOGIN, so CalendarHelper:Initialize() and PrintSavedVariableStatus() (and their debug prints) ran twice per login. Removed the duplicate block. Location: CalendarHelper.lua.
• Fixed two-digit signup numbers rendering as "…" in the event invite list. The signup-order column (SignupNum in CalendarEventInviteListButtonTemplate) was a fixed 14px-wide FontString; a two-digit ordinal (10+) overflowed and ellipsized to a bare "…". Widened it to 20px, which still clears the leader/ready-check icon slot at x=20. The frame's resize grip only redistributes width to the Name/Rank columns, so this column could not be widened by dragging. Location: ClassicCalendarTemplates.xml.
• Fixed the Rank Auto-Confirm rank list omitting empty guild ranks. BuildRankList derived the selectable ranks from the ranks current roster members happened to hold, so any rank with no currently-loaded member never appeared (reported as "only the highest two and lowest two ranks show"). It now enumerates the guild's rank definitions via GuildControlGetNumRanks() / GuildControlGetRankName(i) (1-based, mapped to the 0-based rankIndex used everywhere else), including empty ranks, then tops up from the roster scan as a permission-safe fallback so a restricted client degrades to the old behavior instead of erroring. Location: GuildRankConfirm.lua.
• Fixed the world-buff date picker allowing unbounded future years. The month-navigation arrows (ChangeMonth, ChangeDatePickerMonth) rolled the year forward/back with no limit and nothing validated the year on save, so repeated clicks could create entries years out (the "entries dated into 2029" report). Both navigation paths now clamp through a shared ClampSelectedDateToWindow to a rolling last-year / this-year / next-year window (date("%Y") ±1) — enough headroom to navigate across a December/January boundary, but no further. Pre-existing far-future entries are left intact (they live in the synced store). Location: WorldBuff.lua.
• Fixed the invite-list column headers not lining up over the #, LVL, and ON columns. Those cells aren't left-justified (# is centre-justified, LVL right-justified, ON is a centred dot), but their headers were left-anchored like the Name/Class/Rank headers, so they sat off to one side. In CalendarEventInviteList_AnchorSortButtons the # header is now centred over its cell (x=12), LVL is right-aligned to the cell's right edge (x=207), and ON is centred over the dot (right-75, accounting for the row's ~5px inset). Location: ClassicCalendar.lua.

Changed

• Rank Auto-Confirm is now a native dropdown menu, not a button + floating popup. The UIPanelButton and the custom CalendarGuildRankConfirmPopup (checkbox panel, Done/Re-process buttons) are replaced by a Blizzard UIDropDownMenuTemplate injected into the create/edit invite-list section. Each guild rank is a checkable menu entry (isNotRadio + keepShownOnClick, so multi-select stays open); a title row heads the menu and, in edit mode, a "Re-process Signups" action closes it. The menu's UIDropDownMenu_Initialize builder re-reads the rank list and per-event settings on every open, so checkmarks always reflect current state. This also resolves the see-through popup background (the report that the panel was too transparent) for free — the native dropdown list uses Blizzard's opaque menu backdrop. /calranks debug now reports configDropDown state and /calranks show toggles the menu. Location: GuildRankConfirm.lua.
• Removed the officer view-only Rank Auto-Confirm control. The view-event window's invite-list header is fully occupied by Blizzard's RSVP buttons (Sign Up/Tentative/Decline/Remove), so the dropdown collided with them there; its settings also didn't reliably persist from the view frame (they were gated on the create/edit frame's edit-mode). The control now lives only on the create/edit window, where it fits and functions. Officers who can edit an event still configure ranks via the edit window. Location: GuildRankConfirm.lua.

---

[v1.6.1] (2026-07-11)

New Features

• World-buff entry timestamps. Each entry now records an immutable createdAt (server time, stamped once on add and preserved across edits) alongside lastModified. The Date Received column appends the entry's added time-of-day so it reads as a full date/time stamp; hovering a player name surfaces the last-edited time (when applicable), the left/right-click actions, and the member-only note. createdAt propagates on the wire and is folded into the leaf hash and content tie-break so it converges across the guild. Location: WorldBuff.lua, WorldBuffDB.lua, WorldBuffSync.lua.

Bug Fixes

• Fixed login/logout stutter under world-buff sync (large guilds). getMyHashes — which DeltaSync calls on every guildmate's hash-broadcast — was re-hashing the entire world-buff dataset each time, an O(all-entries) main-thread pass that stuttered during pre-raid login flurries. Item hashes are now per-entry leaf hashes rolled up per item, maintained incrementally on write in an in-memory index (WorldBuffDB._hx); the receive path is a pure lookup with no content hashing. Content is hashed only on an actual edit, or once when the index is first built after login. Location: WorldBuffDB.lua, WorldBuffSync.lua.
• Fixed connected-realm key fragmentation / endless resync. On a connected-realm cluster a bare player name was normalized with the viewer's realm, so the same player fragmented into per-realm and per-case keys (nuksylvshuntm5-atiesh / -oldblanchy / -myzrael / mixed case) that never matched across clients — so peers' item hashes never converged and re-synced forever. NormalizeKey now resolves the canonical Name-HomeRealm via the library roster (short-name → roster lookup), which is identical on every client, and never strips the realm (the fallback is GR:NormalizeName, which adds one). Location: WorldBuffDB.lua.
• Eliminated the redundant guild-roster refresh churn. GuildRankConfirm kept its own GetGuildRosterInfo scan (memberCache/rankList) rebuilt on every GUILD_ROSTER_UPDATE, and re-requested the roster via C_GuildInfo.GuildRoster() — a self-feeding refresh loop. That parallel cache is deleted; rank/level/online/name now read directly from LibGuildRoster (GR:GetMember, GR:GetRoster, GR:GetOnlineMembers), and the re-requests are gone. WorldBuffSync:IsTrustedSender and the WB add-entry autocomplete are likewise library-backed — our world-buff and rank code now makes zero direct guild-roster API calls (the ported Blizzard calendar frames in ClassicCalendar.lua still use their own, unchanged). Location: GuildRankConfirm.lua, WorldBuffSync.lua, WorldBuff.lua.

Changed

• World-buff entries are restricted to current guild members. The add/edit dialog now only accepts a name that resolves to a current guild member via the roster (one of the autocomplete suggestions); a free-typed or non-member name is rejected. Every entry therefore keys to a canonical, cross-client-consistent key by construction, closing the last path by which a viewer-realm-keyed entry could fragment across peers. Location: WorldBuff.lua, WorldBuffDB.lua.
• Dedup migration for legacy fragmented keys. WorldBuffDB:Dedupe re-keys every entry through the canonical NormalizeKey and last-writer-wins merges collisions (with a content tie-break byte-identical to the sync merge, so every client keeps the same survivor), collapsing per-realm/per-case duplicates into one row. Runs once when the roster is ready; /ccwb dedup forces it manually. Received entries are re-keyed on arrival (ApplyEntries) so an un-updated peer can't re-fragment a cleaned store. Location: WorldBuffDB.lua, WorldBuffSync.lua.
• Wire protocol versioned wb: → wb2:, with a one-time data reset. v1.6.1 clients operate in a DeltaSync item space disjoint from v1.6.0, so old-format sync traffic lands on items we don't hold and is ignored rather than merged. Because the v1 data was corrupted beyond repair, the first v1.6.1 load discards the entire world-buff store and starts blank (WorldBuffDB:Init wipes ClassicCalendarWBDB.guilds when the _dataFormat marker is below 2, then stamps it — so it runs exactly once); clean data then syncs back from other v1.6.1 peers. Legacy per-character migration is gated off on the v2 format (Migrate returns early), so the old arrays can't re-seed corruption. Location: WorldBuffSync.lua, WorldBuffDB.lua.
• World Buff window UI polish. Player names and mains display as their canonical Name-Realm (resolved on render, so pre-existing entries show the realm too); the add-entry autocomplete lists full Name-Realm on an opaque, TOOLTIP-strata dropdown (readable on the dark backdrop, no longer clipped behind the dialog); the Player Name column left-justifies under its header via an explicit child FontString (a Button re-centers its own text, which is why it was indented); rows are zebra-striped (the scroll child is now sized to the viewport each render, so rows span the full width instead of collapsing to the 1px child); and hovering a name shows a tooltip with the click actions and a note that a member who has left the guild can only be deleted, not edited. Location: WorldBuff.lua.

Hardening

• True FNV-1a (no double-mantissa overflow). The hash multiply is now done in 16-bit halves so every intermediate product stays exact, replacing hash * 16777619 which overflowed the 53-bit double mantissa and silently dropped low bits (degraded collision resistance in the convergence-critical roll-up hash). Applied identically to fnvStep/settingChecksum (WorldBuffDB) and contentChecksum (WorldBuffSync) so DB-side and sync-side tie-breaks stay in lockstep. Mirrors LibGuildRoster's fnv1a32. Location: WorldBuffDB.lua, WorldBuffSync.lua.
• Clock-skew-safe timestamps. Synced lastModified / setAt / wipe-epoch stamps use GetServerTime() (identical on every client) instead of local time(), so LWW ordering and the wipe epoch don't depend on a member's OS-clock skew. Location: WorldBuffDB.lua.
• Tombstones kept forever. Deleted entries are never garbage-collected, so a deletion can't resurrect from a peer that GC'd on a different schedule, and peers can't diverge on GC timing. GarbageCollect is now a no-op. Location: WorldBuffDB.lua, WorldBuff.lua.
• /ccwb diagnostics. Counters (getMyHashes calls / reassembles / memo-hits, one-time hash-index builds, inbound/outbound sync), /ccwb log for a timestamped live trace, /ccwb reset to zero counters, and /ccwb dedup to force the duplicate-collapse. Location: WorldBuffSync.lua.

[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
