Re: Different behavior for coroutines in Lua and LuaJIT

[Graham Wakefield <lists@...>]

Does this mean that using large numbers of coroutines (e.g. hundreds concurrently, or hundreds of thousands over a program's lifetime) may be more expensive in luajit 1.x than plain lua?  And if so, is this also likely to be the case in the eagerly anticipated luajit 2.0?

Thanks,

Graham

You cannot yield from a thread in LuaJIT 1.x if you don't give it

its own C stack. The standard coroutine.create() and coroutine.wrap()

functions already do this for you. Rewrite your example in pure Lua

code and you'll see it works out-of-the-box.

If you want to create Lua threads from C (not recommended, it's not

faster), you need to read this: http://luajit.org/coco_api.html

Scroll down to lua_newcthread().
