gollark: I should assign unique IDs to the other sandbox escape bugs.
gollark: My "fix" is this:```lua--[["Fix" for bug PS#E9DCC81BSummary: `pcall(getfenv, -1)` seemingly returned the environment outside the sandbox.Based on some testing, this seems like some bizarre optimization-type feature gone wrong.It seems that something is simplifying `pcall(getfenv)` to just directly calling `getfenv` and ignoring the environment... as well as, *somehow*, `function() return getfenv() end` and such.The initial attempt at making this work did `return (fn(...))` instead of `return fn(...)` in an attempt to make it not do this, but of course that somehow broke horribly. I don't know what's going on at this point.This is probably a bit of a performance hit, and more problematically liable to go away if this is actually some bizarre interpreter feature and the fix gets optimized away.Unfortunately I don't have any better ideas. Also, I haven't tried this with xpcall, but it's probably possible, so I'm attempting to fix that too.]]local real_pcall = pcallfunction _G.pcall(fn, ...) return real_pcall(function(...) local ret = {fn(...)} return unpack(ret) end, ...)end local real_xpcall = xpcallfunction _G.xpcall(fn, handler) return real_xpcall(function() local ret = {fn()} return unpack(ret) end, handler)end```which appears to work at least?
gollark: Fixed, but I don't really know how or why.
gollark: ... should I create a bug report?
gollark: It returns two, actually. The second one. I don't know *what* the first one is doing.
