📃 Lua Alpha

I wrote a test script, and ll.DumpList2String is literally the only ll list function that rejects booleans in it's list, and gives the error "non-LSL value in list" instead: print(ll.DumpList2String({true, false}, ",")) [9:41 AM] Object: Object [script:New Script] Script run-time error [9:41 AM] Object: lua_script:1: non-LSL value in list [C] function DumpList2String lua_script:1 I expected it to print 1,0 instead, like ll.List2CSV does: print(`{ll.List2CSV({true, false})}`) --> 1, 0 I do not have a script that stores booleans in lists that would benefit from this, so, I removed my vote from this post. Mostly I just like that ll.DumpList2String is still a very useful function even in luau Verification script and it's output are attached, generated from https://github.com/secondlife/lsl-definitions/pull/199

After running continuously for several weeks, my emulator script halted with this error: A Simple Sun-Earth-Moon emulator.: 0.3 [script:Sun-Earth-Moon demo] Script run-time error Failed to perform mandatory yield lua_script:159 function emulation_step [C] function _tick [C] function timer_event_wrapper [C] function _handleEvent The script, or an earlier version thereof, has halted similarly on at least two previous occasions. This, however, is the first time I've been on Sim when the crash occurred to receive the error message. Full script @ https://pastebin.com/PAg61t1K The instance of the object that crashed is at https://maps.secondlife.com/secondlife/Builders%20Brewery%20Sandbox/36/69/498 Anyone may take a full perms copy. I have not reset the script.

While this caveat behavior is known and possibly relied upon by lsl scripts. Nobody should be writing a slua script expecting this security issue to exist. So if possible could a ll.HTTPRequest from slua, only trigger the http_response event in the slua script making the request. Or a dataserver request also respond only to the requesting script. Not in any other, script regardless of their platform runtime. This might be a slight pain to implement to keep the behavior for lsl on luau scripts, but I think worth it for slua Test Place 2 scripts in a prim save them with the following content ll.HTTPRequest("https://secondlife.com",{},"") function http_response(id,stat,meta,body) ll.OwnerSay(`{ll.GetScriptName()} = {stat}`) end Note that on saving of the second script you get 2 owner says, one from each script stating the response status. Ideally this behavior should be avoided for slua. Alternate suggestion It was suggested it may be possible to instead add a new HTTP_* flag Something like ll.HTTPRequest( "https://secondlife.com", { HTTP_PRIVATE_REQUEST, TRUE }, "" ) This would not work for dataserver events though

default { state_entry() { // editor line 0 integer i = 0.5; // line 1 }} -- > Line 2: 'integer i' assigned a float value. The editor could start with line 1 (like with SLua), or the messages return the error line - 1.

Using strict type checking doesn't display warnings in the Script Warning/Error window --!strict local function add(a: number, b: number): number return a + b end local result1: number = add(3, 4) -- Should work fine local result2: number = add("3", 4) -- Should trigger a type error in strict mode This code in Luau/Roblox displays this warning: Type Error: (8,29) Type 'string' could not be converted into 'number'

The SLua code below demonstrates the problem. Two vectors, multiplied, results in a vector answer rather than a number. v1 = vector(9, 2, 7) v2 = vector(4,8,10) v3 = v1 * v2 ll.OwnerSay(typeof(v3) .. ": " .. tostring(v3)) Program output: vector: <36.00000, 16.00000, 70.00000> Reason for identifying as a bug: The SL Wiki indicates that the dot product should return the sum of the products of the vector elements. In this case, the expected result should be 122.0. What is returned instead is simply the vector of the products of each element.
