MarcelineVQ 944e398e41 minimapicons: add quest available tracking to minimap 
Reads quest giver status from unit+0xCB8 (populated by client's
SMSG_QUESTGIVER_STATUS packet handler) to show yellow ! icons on the
minimap for NPCs with available quests. Uses the vanilla gossip frame
AvailableQuestIcon texture. Enabled by default, togglable from the
tracking dropdown like other NPC categories.

Unreleased Changes

Track notable changes here between releases. Clear this file when cutting a new release (move contents into the release notes on Codeberg).

What's New

  • World Markers - place up to 5 animated Cataclysm-style markers at any position in the world. Slash commands (/wm 1, /cwm), keybindings, full Lua API, and automatic group sync between WeirdUtils users. Requires party/raid leader or raid assist.

  • DPSLog (COMBAT_LOG_EVENT) - unified TBC/WotLK-style COMBAT_LOG_EVENT system with 30 subevents across 23 hooks. Provides a single event (slot 549) with subevent strings (SWING_DAMAGE, SPELL_HEAL, SPELL_AURA_APPLIED, etc.) instead of vanilla's fragmented per-type events. Includes embedded addon for parsing. Not yet in DLL_README.

  • Interact - smart interaction helpers: "Interact Nearest" right-clicks the closest interactable NPC or object within 5 yards, "Loot All Corpses" bulk loots nearby corpses. Keybindings and Lua API. Already documented in DLL_README but not yet released.

  • Crash Fix (framecrash) - prevents crashes from stale UI frame anchor pointers. Already documented in DLL_README but not yet released.

  • Outlines - renders glowing colored outlines around units. Already documented in DLL_README but not yet released.

  • Addon Profiling Stub (addonperf) - TBC+ addon CPU profiling API stub (GetScriptCPUUsage). Internal/experimental, not in DLL_README.

  • Minimap Quest Tracking - shows nearby NPCs with available quests (yellow !) on the minimap. Reads the per-player quest status cached on unit objects by the client's SMSG_QUESTGIVER_STATUS handler. Enabled by default in the tracking dropdown, togglable like other NPC tracking categories.

Enhancements

  • Clickthrough: Lootable corpses now click-through over players. Previously only interactable NPCs (vendors, quest givers) and game objects would win over a blocking player. Now dead units with the lootable flag are also prioritized, so you can loot corpses through the player crowd without having to reposition.

  • World Markers: Disabled in battlegrounds via Map.dbc mapType check. Markers cannot be placed while in a battleground instance.

  • Clickthrough: Reduced log noise -- logging changed from file to console-only. Also ignores assets_backup directories in custom asset scanning.

Bug Fixes

  • World Markers: Fixed marker placement over game objects -- re-raycast now uses terrain-only flags to find the ground position beneath a GO, instead of placing the marker at the GO's collision point.

  • DPSLog: Fixed dynamic event slot search and environmental damage parameter ordering.

  • Addon System: Fixed addon files not loading -- switched from @hasField to @hasDecl for compile-time module introspection.

Internal / Performance

  • Transform44 Profiling - render pipeline profiling module with 39 hotspot hooks, A/B testing framework for comparing baseline vs optimized code paths, SSE replacements for ClipPolygonToSinglePlane (4x), BuildTrianglePlanes (10x), rotateMatrixByAxisAngle (4.3x), RayTriangleIntersection (1.3x), multiplyMatrix4x4 (4.3x).

  • VanillaFixes Math Polyfill - 17 UnitXP x87 FPU replacement hooks verified via Ghidra prologue/epilogue disassembly and benchmarked against original WoW.exe bytes. Hooks install in lateInit() to clobber UnitXP's hooks with correct calling conventions (thiscall vs fastcall verified from assembly). A/B tested via bitmask toggle.

    Micro-benchmark results (x86 Linux harness, original x87 bytes mmap'd executable):

    Winners (SSE faster):          Neutral (~1.0x):            Losers (x87 faster):
rotMat3x3:       2.1x (158->72)   matMulVec3:  1.0x         dotProduct:       0.4x (5->11)
rotMat4x4:       2.1x (162->76)   multiply3x3: 1.0x         evaluatePolynomial: 0.6x (11->16)
planeNormal:     1.7x (58->33)    crossProduct: 1.0x        squaredMagnitude:  0.7x (7->9)
transformAABox:  1.2x (89->69)    applyTranslation: 0.9x    vec3MulScalar:     0.8x
vecMulMat4:      1.1x             scaleByVec:  0.9x         vec3MulAssign:     0.8x
scaleByScalar:   1.1x (some runs)                            quatMulMat4:       0.8x

    Losers are at function call overhead floor (original x87 is 5-11 cycles, close to bare CALL/RET cost). Future direction: patch original bytes in-place at load time to eliminate call overhead entirely.

    Also includes CriticalSection SpinCount=4000 optimization (from UnitXP) and blit_hub memcpy fast paths for matching pixel formats.

  • Math SSE Benchmark Harness (zig build bench / zig build run-bench) - standalone x86 Linux micro-benchmark that extracts original x87 function bytes from WoW.exe via Ghidra, mmaps them executable, and profiles against our SSE replacements. Fresh data each iteration to avoid overflow/denormal artifacts. Correctness validation included.

  • Glyph Shadow Cache - direct-mapped O(1) bypass for the game's 4-bucket hash table in GetOrCreateCharacterGlyph. Reduces glyph lookup from ~3.65% frame time.

  • MPQ File Cache (filecache) - 2-way set-associative cache for File_FindInArchive (0x6549a0). Skips the MPQ chain walk and per-archive hash table probe on repeat file opens. Cache hits cost ~1000 cycles vs ~30000 cycles for full search. 60-90% hit rate during gameplay, saving 6-160ms per 15s reporting period depending on scene load. Validated via game's own FindAndIncrementResourceReference to handle archive lifecycle.

  • Timer Fix (VanillaFixes port) - TSC calibration, OS timer resolution (0.5ms via NtSetTimerResolution), and Windows 11 power throttling disable. Ported from hannesmann/vanillafixes. Primarily benefits native Windows; no measurable impact on Wine/Linux but applied unconditionally.

  • MPQ File Cache - hooks File_FindInArchive (0x6549a0) to cache archive lookup results. First open does full MPQ chain walk (~60K cycles), subsequent opens hit direct-mapped cache with filename verification (~300 cycles). 80% hit rate in testing. Moved from standalone file_perf module to transform44 sub-module (file_cache.zig).

  • Logging Module - centralized logging with auto-prefix, file and/or console routing. All modules now route output through the shared Logger.

  • Addon System Refactor - module list now derived from build.zig, inactive addon prefixes pruned at runtime. Fully data-driven.

  • Shared Offsets - consolidated shared game offsets and accessor functions into offsets.zig and wow.zig, eliminating per-module duplication.

  • Build System - default optimize changed from Debug to ReleaseFast (works around Zig fastcall inreg LLVM bug). Logging available in all modes except ReleaseSmall.

To Explore

  • Driver env vars on load - set environment variables like RADV_TEX_ANISO=16 from the DLL at load time, allowing driver-level anisotropic filtering while setting the in-game option to off/low. Avoids the double-filtering performance hit of game AF stacked on top of driver AF. Same approach could apply to other Mesa/RADV/DXVK knobs.
