Hi,
We are using a http-req lua action to dynamically set some app specific
metadata headers. The lua handler connects to a upstream memcache like
service over tcp to fetch additional metadata.
Functionally everything works ok, but I am seeing that socket.settimeout
has no effect. Irrespective of what I set in settimeout if the upstream
service is unreachable, connect always timesout at 5 seconds, and read
timeout around 10 seconds. It seems like settimeout has no effect and
it always picks defaults of 5 seconds for connect timeout and 10 seconds
for read timeout.
For the connect timeout, it seems this is a hardcoded default value in
src/hlua.c:
socket_proxy.timeout.connect = 5000; /* By default the timeout
connection is 5s. */
If it's possible, can you try the patch attached (for the 1.7.x branch)
? But please don't use it in production yet ;-)
Haproxy conf call:
http-request lua.get_proxy
Lua code sample:
function get_proxy(txn)
local sock = core.tcp()
sock:settimeout(2)
status, error = sock:connect(gds_host, gds_port)
if not status then
core.Alert("1 Error in connecting:" .. key .. ":" .. error)
return result, "Error: " .. error
end
sock:send(key .. "\r\n")
....
....
core.register_action("get_proxy", { "http-req" }, get_proxy)
