Hello,
We're desperately looking for ways to implement efficient lua_call()
and lua_pcall() timeouts. Yes, they are easily implementable with
a debug hook. However, running a hook on every instruction (or few
instructions) is not best for performance. Ideally, hooks which
check for timeouts need not have granularity lower than tens of
microseconds. Is there a way to do it with LuaJIT already? Could
this be a sponsored feature?
Ideally, it would be great to integrate LuaJIT into our
virtual machine, so that it's possible to do a reduction (context
switch) while preserving the context of a running call.
Thanks,
