Hi, I think I've found a bug in core.msleep (and core.sleep);
foo.lua; core.register_service("foo", "http", function(applet) core.msleep(1) local body = "hello" applet:set_status(200) applet:add_header("Content-Length", string.len(body)) applet:start_response() applet:send(body) end) haproxy.cfg global lua-load foo.lua defaults mode http timeout client 150000 timeout server 3600000 timeout connect 5000 timeout queue 5000 listen l bind 127.0.0.1:6000 http-request use-service lua.foo -- steps to reproduce; curl 127.0.0.1:6000 this will not respond at all. If you comment out the core.msleep(1) line, you get the expected 200 response. This seems to occurs wherever core.msleep is used but I've only confirmed this behaviour in register_service and register_action functions. Regards, Robert Newson.
