SLua Announcements

We're rolling out new SLua Alpha sims to Aditi, with quite a large number of changes! * Experimental changes to the Luau garbage collector to make garbage collection much faster. * Update the underlying Luau version we use to 0.686 * Change how VM interrupts work so that triggering a metamethod after calling a particularly long-running ll.Something() function no longer triggers a "failed to perform mandatory yield" error * Make garbage collection more aggressive as scripts near their memory limit, reducing the likelihood of unexpected out-of-memory errors when making repeated large allocations. * Make ll.GetFreeMemory() and friends actually return a number that makes sense. * Sundry bugfixes

Updated SLua to merge in upstream changes up til Luau v0.668 Added support for __tojson metamethod, called during JSON serialization Greatly improved performance of ll.SetLinkPrimitiveParamsFast() with many PRIM_LINK_TARGET s A forced sleep penalty is now applied to scripts that stay in blocking code far past their scheduled time slice for 5x the amount they ran over - Previously this penalty was much smaller in SLua, but ran into issues with resource starvation where blocking scripts were taking the lion's share of the script time - For reference, Mono does a 10x penalty - This was especially obvious in cases of expensive ll.SetLinkPrimitiveParamsFast() calls tovector() and toquaternion() now only allow whitespace around characters, trailing junk causes them to return nil - This is distinct from LSL which allows <1,2,3WHATEVER!!! Scripts that crashed with an error can now be reset normally Simulator is rebased to include changes from upcoming simulator release A handful of crash fixes 🙂
