The remote was previously a distribution-only point for pre-built DLLs.
This opens the source.
- LICENSE: Unlicense, with a GPL-3.0 carve-out for src/dpslog/WeirdDPSMate
(a DPSMate fork that keeps its own license)
- README.md replaces the stale internal one with the user-facing docs from
DLL_README.md, swapping the 'Why No Source Code?' section for build and
layout notes. DLL_README.md is dropped; one README now serves both.
- RELEASING.md: drop the trim-the-README-per-release dance and the
remote/WeirdUtils/ distribution clone, both obsolete now
- gitignore agent/editor scratch, build caches, the vendored WSBT addon,
and the WeirdThreat/uwu-logs checkouts (separate upstream repos)
- Commit outstanding module work: superweirdo, clickthrough portal visuals,
transform44 decompiles, worldmarkers demo presets, tools/
Adds bone_sse64.zig as an f64-intermediate port of transformMatrix4x4, used as
the active hook. M2 bone matrices are built and multiplied as [16]f64 and only
narrow to f32 on final store into the bone output buffer -- matching the x87
original's rounding profile (wide intermediates, single f32 store) and keeping
M2 vertex positions aligned with the terrain/projected-texture pipeline.
Also fixes, in both bone_sse (f32) and bone_sse64:
- Pre-billboard tx/ty/tz accumulation order (row 0 = pz+px+py; rows 1/2 = pz+py+px)
- Post-billboard pos_y/pos_z accumulation order (py+pz+px)
- Post-billboard scale-recompute accumulation order (row0 + row2 + row1)
- Billboard types 2/4 normalize using f64 intermediates (load-bearing for camera
basis vectors -- pure f32 drifted from x87 by a ULP per axis and caused
particle emitters to jitter on camera motion)
Additional bone_sse64-specific changes:
- Local attachmentRecursion64 that recurses into transformImpl_SSE64 instead of
bone_sse.transformImpl_SSE, so attached child models stay on the f64 path
- child_padding (this+0x84) computed with f64 intermediates
bone_sse remains the reference f32 implementation; its struct fields, inline
helpers, and section-loop fns are now `pub` so bone_sse64 can share them
(types/interpolation helpers/post-loop loops). Artifact size is unchanged.
build.zig adds bench_bone_sse64 object; src/bench/main.zig runs the new variant
through the same warmup/timing harness and prints SSE vs SSE64 vs BASELINE
cycles plus a parity check.
si_frustumCullBBox (0x686000, center+radius variant) was culling any
bounding volume whose center had view-space z < 0, but an object whose
center is behind the camera can still have its front extent inside the
frustum (think of standing next to a big WMO -- the building's center
can be a few units behind you while its front wall is still in frame).
Use the bounding sphere rather than the center point: only cull when
the closest point of the sphere is itself behind the camera, i.e.
center.z + |radius| < 0. Straddling cases now fall through to the
near-plane passthrough and get rendered.
si_frustumCullBBox8 (0x686180, 8-corner variant) already does the
right thing here -- it only returns "all behind" when every transformed
corner has z < 0, which is a true convex-hull test for an AABB.
Current state CRASHES on load due to pre-alloc hooks with wrong calling
conventions. pushcclosure hook is still enabled with partially disabled
others. Needs all pre-alloc hooks disabled or CCs fixed before use.
Implemented:
- Full 5.1 tri-color incremental GC
- 5.1-style singlestep budget loop (replaces chunk-based approach)
- Per-step rdtsc timing (ZGCStats returns max_step_us, atomic_us)
- Configurable gcstepsize/gcstepmul/gcpause via ZGCTune()
- Pre-alloc GC hooks for 7 API functions (5.1 luaC_checkGC pattern)
- Stress test addon: /gclife, /gcsweep, /gccompare
Broken:
- Pre-alloc hooks have CC mismatches causing immediate crash on load
- pushfstring is cdecl variadic, not fastcall (removed)
- pushstring has ambiguous CC (removed, covered by pushlstring)
- pushcclosure hook still active -- may be causing the crash
- Half-initialized objects cause garbage gcptr under heavy stress
weirdperformance: re-enabled luagc.install() + luastr + luavm
- Per-step rdtsc timing: ZGCStats returns max_step_us and atomic_us
- AllocBench /zgcstats frame shows step/atomic timing with color coding
- /gccompare command for timing forced GC cycles
- Honor lua_setgcthreshold forced collections (collectgarbage() with low
threshold now triggers GC instead of being silently ignored)
- Disable luaalloc in weirdperformance when luagc is active (no conflict)
- Closures go to grayagain (covers all upvalue mutation paths)
Adds the infrastructure for generational GC on top of the incremental sweep:
- luaalloc: per-page age bitmap (1 bit per slot) lazily allocated with each
slab page. Public isOld/setOld/setYoung/clearAllAges API. Segment-indexed
for O(1) lookup in the write barrier.
- luagc: write barrier via Detour on lua_table_set_value. Records touched
old tables in a 4096-entry set. Pure bitmap read on every table write.
- luagc: minor/major cycle distinction. First collection, touched overflow,
and every 32nd minor are forced to major. Major clears the age bitmap and
touched set; minor preserves both. cycleFinish repopulates the bitmap by
walking rootgc after a full sweep completes.
Both cycles still run lua_gc_full_collection for now -- the custom minor
mark that actually skips untouched old objects is the next layer.
Previous crash investigations proved Detours on lua_table_set_value are
safe; earlier failures were from simultaneous marked-byte modifications,
not the Detour itself.
Rootgc sweep chunked by temporarily NULLing a next pointer and calling
the original lua_gc_remove_objects on the truncated sublist. Swept
survivors are detached to a separate list to prevent re-sweeping.
Lists reconnected after final chunk.
Birth-mark via binary patch of luaC_link immediate byte (0x6F7B37)
ensures new objects born during sweep survive.
Profiling shows sweep chunks at 0-9ms each (was 225ms avg, 5s worst).
Remaining bottleneck: atomic mark (80ms) + udata/string sweep (44-92ms).
Incremental GC: atomic mark + batched rootgc sweep. Crashes from
objects born white during sweep -- needs birth-mark barrier fix.
Link hook (luaC_link) calling convention verified but interaction
with sweep_ptr at list head needs solving. Disabled pending fix.
AllocBench: realistic addon-like data structures (combat events,
player damage breakdowns with metatables, aura trackers with
closures). Cross-references shared spell/unit caches. These
complex structures reveal GC as the true stutter source -- simple
flat objects don't trigger meaningful GC pauses.
Removed arena pre-reservation (was fragmenting 32-bit address space).
Profiled 67M Lua allocations to find hot sizes. Lua table hash nodes
are 40 bytes, so hash tables produce allocs at 80, 160, 320, 640,
1280, 2560 (2..64 nodes). Added classes at these exact sizes.
Fixed size class LUT: was 16-byte granularity (size 22 mapped to
class 32 instead of 24). Now direct 1:1 lookup table, 4KB, one
byte load per alloc with zero computation.
Other changes:
- Removed pool_ctx==0 passthrough and seg_val==0 fallback (dead code)
- Removed pool_ctx param from slabFree/slabRealloc
- Added optional PROFILE mode with size histogram dump to log file
- Added AllocBench addon (/allocbench) for in-game benchmarking
Hook 0x686940 (testAABBFrustum): SSE center/extent P-vertex method replaces
x87 sign-bit corner selection. ~160M cycles in profile, 50% rejection rate.
Hook 0x686180 (FrustumCullBoundingBox 8-corner): SSE replacement transforms
all 8 AABB corners through view-proj, horizon buffer scan with 4-wide test.
Fix behind-camera bug in both FrustumCullBoundingBox variants (0x686000,
0x686180): original returned 0 for behind-camera objects, callers interpret
0 as "visible, render it". Now returns 2 (occluded) when all geometry is
behind the camera (Z < 0 in clip space).
- Restore MSVC ABI (was accidentally GNU since v0.6.0, broke .CRT section)
- Replace game allocator with Windows process heap for filecache and
libdeflate malloc/free - game allocator not initialized during DllMain
when injected via CreateRemoteThread
- Defer timer calibration (Sleep 500ms) to lateInit - blocks under
loader lock during DllMain
- Remove exported malloc/free symbols from DLL
- Eliminate addObject compilation units for SSE files - direct @import
with AVX target instead
- Heap-allocate filecache (was 9.3MB static BSS)
- Strip transform44 of performance/ externs, pure profiling only
- Rename performance/ to weirdperformance/ to match module convention
- Skip default-off modules in all-variants build step
- Remove dead debug vars and stride logging from particle_sse
