This essentially re-does the work of #875 on top of master. This is what I did to check that Cosmo's Lua extensions still worked: ``` $ build/bootstrap/make MODE=aarch64 o/aarch64/third_party/lua/lua $ ape o/aarch64/third_party/lua/lua >: 10 10 >: 010 8 >: 0b10 2 >: string.byte("\e") 27 >: "Hello, %s" % {"world"} Hello, world >: "*" * 3 *** ``` `luaL_traceback2` was used to show the stack trace with parameter values; it's used in `LuaCallWithTrace`, which is used in Redbean to run Lua code. You should be able to see the extended stack trace by running something like this: `redbean -e "function a(b)c()end a(2)"` (with "params" indicating the extended stack trace): ``` stack traceback: [string "function a(b)c()end a(2)"]:1: in function 'a', params: b = 2; [string "function a(b)c()end a(2)"]:1: in main chunk ``` @pkulchenko confirmed that I get the expected result with the updated code. This is what I did to check that Lua itself still worked: ``` $ cd third_party/lua/test/ $ ape ../../../o/aarch64/third_party/lua/lua all.lua ``` There's one test failure, in `files.lua`: ``` ***** FILE 'files.lua'***** testing i/o ../../../o/aarch64/third_party/lua/lua: files.lua:84: assertion failed! stack traceback: [C]: in function 'assert' files.lua:84: in main chunk (...tail calls...) all.lua:195: in main chunk [C]: in ? .>>> closing state <<< ``` That isn't a result of these changes; the same test is failing in master. The failure is here: ```lua if not _port then -- invalid seek local status, msg, code = io.stdin:seek("set", 1000) assert(not status and type(msg) == "string" and type(code) == "number") end ``` The test expects a seek to offset 1,000 on stdin to fail — but it doesn't. `status` ends up being the new offset rather than `nil`. If I comment out that one test, the remaining tests succeed.
