File cache (filecache module):
- Moved from transform44 sub-module to standalone src/filecache/
- 2-way set-associative cache (32768 sets x 2 ways) with FNV-1a hash + finalizer
- Fixed negative cache hit crash: zero output params before returning 0
(FindFileInArchive reuses filename slot for out_outer_archive)
- Fixed path 2 crash: set out_outer_archive on all cache hit paths
- Fixed stale block_entry crash: cache block index instead of raw pointer,
recompute from archive+0x290 on each hit
- Fixed archive-freed crash: use game's FindAndIncrementResourceReference
(0x650780) instead of manual +0x38 increment -- validates archive is alive
- Periodic stats dump with projected time savings (hit=~1000cy vs miss=~30000cy)
Timer fix (transform44 sub-module, ported from VanillaFixes):
- TSC calibration via QPC reference over 500ms
- Enables TSC mode if game was using GetTickCount fallback
- NtSetTimerResolution for 0.5ms OS timer granularity
- SetProcessInformation to disable Windows 11 power throttling
- Always-on (no A/B toggle -- no measurable impact on Wine/Linux)
Hook File_FindInArchive (0x6549a0) with a direct-mapped filename-verified
cache. First open does the full MPQ chain walk (~60K cycles), subsequent
opens hit the cache (~300 cycles). 80% hit rate in gameplay testing.
Cache design: 16384 entries, FNV-1a hash for slot index, raw filename
comparison (128 bytes) for collision safety. Stores outer_archive,
inner_archive, and block_entry per file. Negative cache for not-found files.
Refcount at +0x38 incremented on all output archives to match original
File_FindInArchive behavior (verified via Ghidra: FindAndIncrementResourceReference
at 0x650780, DecrementResourceReference at 0x6507e0).
Also: default build changed to ReleaseFast (works around Zig fastcall inreg
bug in Debug mode), logging gate changed to != ReleaseSmall, file cache
integrated as transform44 sub-module with A/B comparison timing in readout.
- Eliminate hardcoded module_names in addons.zig — now derived from
build.zig via all_module_names build option
- Add module_active.zig runtime registry: main.zig registers isActive
pointers during install(), addons.zig queries them without importing
each module directly
- Prune embedded file prefixes at startup: after all modules claim
mutexes, build a runtime active_prefixes table excluding modules we
don't own. findEmbeddedFile searches only active entries — no
per-lookup isActive check on the hot path
- Tag both addon and asset prefixes with module_name so pruning applies
to all embedded files for a module
- Rename src/markers/ → src/worldmarkers/, src/outline/api.zig →
src/outline/outline.zig to follow {name}/{name}.zig convention
Registers GetAddOnMemoryUsage, UpdateAddOnMemoryUsage, GetAddOnCPUUsage,
UpdateAddOnCPUUsage, ResetAddOnCPUUsage, and GetScriptCPUUsage as global
Lua functions. All stubs for now — implementation will hook lua_Alloc
and FrameScript dispatch for per-addon tracking.
Build options now provide addon_name, addon_hidden, and file lists per
module. addons.zig derives everything from these — no hardcoded module
list. Added addon_hidden flag (WorldMarkers uses it to stay unlisted).
Changed dpslog default to enabled.
Replace console.zig with logging.zig: per-module Logger with auto
[name] prefix, optional file output, and destination routing. Convert
all modules from manual [name] prefixes and global con.print to Logger
instances. Remove redundant "Module loaded" lines. Replace
OutputDebugStringA in outline/tracker with Logger. Add dpslog module
with structured combat log events (SPELL_DMG, PERIODIC, HEAL, MELEE).
Add clickthrough module and bigcursor D3D9 cursor scaling.
Remove the embedded Screenshot addon (TOC + Lua) and WeirdUtilsScreenshot()
Lua function. Compression quality is now controlled entirely via a CVar
(saved to config.wtf), read fresh on each screenshot. CVar 0 disables PNG
and falls through to original TGA.
Take over native MiniMapTrackingFrame to show a tracking spell
dropdown (Hunter Track X, Sense Undead/Demons, Find Herbs/Minerals)
plus NPC tracking categories with icons extracted from the 3.3.5
client (Auctioneer, Flight Master, Mailbox, Repair, etc.).
build.zig scans module addon/ and assets/ directories, passes file
lists as build options. main.zig uses comptime helpers to @embedFile
each path and build the AddonPrefix table automatically. Adding or
removing files no longer requires editing main.zig.
Also renames markers addon files to match WoW addon name
(Markers.toc → WorldMarkers.toc, Markers.lua → WorldMarkers.lua)
and auto-generates loadAddonsDetour from the same module metadata.
- dataassets module renamed to customassets everywhere (build flag,
source, DLL variant name, docs)
- Markers addon renamed to WorldMarkers (addon path, .toc, .lua,
Bindings.xml header, Lua globals, debug log prefix, mutex name)
- All 9 module mutexes now use WeirdUtils_ prefix to avoid
collisions with other DLLs in the same process
Root cause: hook.fastcall used "r" constraints + explicit MOV to set
ECX/EDX. LLVM can allocate "r" inputs to clobbered registers, causing
cross-assignment (ecx_in→EDX, edx_in→ECX) or function address stomping
when func lands in ECX/EDX. Debug works by luck (trivial regalloc);
Release optimizes aggressively and hits the conflicts.
Fix: explicit "{ecx}", "{edx}", "{eax}" register constraints in zhook
fastcall — compiler places values directly, no MOV needed, no ambiguity.
Also fix 9 inline asm blocks across main.zig, interact.zig,
screenshot.zig, markers.zig missing ECX/EDX clobbers after CALL
instructions. Without clobbers the optimizer assumes registers retain
input values after the call — stale reuse in release builds.
Other changes in this commit:
- Rename markers→worldmarkers (build flag, DLL, Lua table)
- Rename assetfix→looseassets
- lua.zig: add .never_tail to pushcclosure, pcall, openlib, pushnumber
- Move internal marker functions into WorldMarkers Lua table via openlib
- Remove unused GetCurrentAreaId function
- Fix cleanup_file_handle_hook.original() → .callOriginal()
The marker cleanup hook on CleanupWorldAndEntities was never installed —
markers.installHooks() was missing from install() in main.zig. Entities
created via WorldMarker were never cleaned up before the game's atexit
handler iterated the hash table over freed heap memory.
Key changes:
- Add markers.installHooks() call (the actual crash fix)
- Replace manual install/uninstall/shutdown lists with a single modules
table that drives all three phases — prevents this class of bug
- Gate marker Lua functions, addon, and keybindings behind isActive()
so they're skipped when another DLL owns the hooks
- Add world_cleanup_hook.detach() to removeHooks() (was missing)
- Migrate from vendored libs/hook to external zhook dependency
- Unify installHooks return types to void across all modules
- Add diagnostic logging to marker cleanup (temporary, for testing)
Assetfix: hook CheckFileExistence to serve loose Data\ files. The original
flags|1 approach failed because game paths contain backslashes, causing
CheckFileExistence to skip BuildFilePath and check the raw path (no Data\
prefix). Fix: write the correct Data\-prefixed disk path to the output buffer
directly and return 1, bypassing the original function for hash map hits.
This preserves hook chaining (filename argument is never transformed).
Also adds transmogfix (transmog update coalescing), minimapicons (stub),
new build options for all three modules, mutex-based multi-DLL safety,
embed .skin data into .m2 models, and various module improvements.
Hook 5 intercepts loadModelFromFileAsync (0x71d4e0) to synchronously load M2
model data for fake in-memory file contexts. processLoadedModelData returns 1
and entities are created, but file context cleanup is currently skipped (leaks
0x60 bytes per load) due to a crash in the cleanup path, and there's a later
EIP=0 crash during the game main loop that needs investigation.
Also adds: combatlog module stub, framecrash anchor vtable hooks (GetRelativeTo
and GetWidth/GetHeight crash guards), embedded Raid_UI_FX model assets with
skins and textures, WU_XYZ debug model.
Markers: client-side world object system using CreateGameObject. Places
M2 models at arbitrary world positions via Lua commands (/mark test,
/mark pos). Includes embedded addon, xyz.m2/blp assets served from DLL
memory, position helpers from unit movement struct, and object lifecycle
management (create, cleanup, reposition, alpha, animation).
Framecrash: stub module with reference to crash at 0x007A2452.
Console: debug output via AllocConsole/WriteConsoleA, compiles out
entirely in non-Debug builds. Used by markers and file serve logging.
Build: markers added to feature flag matrix and all-variants step.
Main: conditional markers import, Lua function registration, embedded
addon + asset file serving, console init/deinit lifecycle.
Outline README: added misc planned features and debug mode notes.
- Each module (outline, interact, screenshot) now has its own addon/
subdir with .toc, .lua, and Bindings.xml
- Core WeirdUtils addon lives in src/core/addon/
- build.zig supports compile-time feature gating via -D options
- main.zig uses build_options for conditional imports and addon embedding
- Module addons only load when their module is compiled in
- 'zig build all-variants' produces full.dll + 3 single-module DLLs
