Dearest HAProxy people, I've been trying out 1.6 dev3 with lua support, and trying to start lua tasks seems to not be working.
Using this configuration
global
lua-load /lua/lol.lua
debug
maxconn 4096
backend shard_b
server db01 mysql_shard_b:3306
backend shard_a
server db01 mysql_shard_a:3306
listen mysql-cluster
bind 0.0.0.0:8001
mode tcp
balance roundrobin
use_backend shard_b
And this lua function
core.register_task(function()
while true do
core.Alert("LOLOLOLOLOL")
end
end)
I'd always get a timeout error starting the registered function.
The problem lies as far as I can tell in the fact that is possible for
now_ms to not change (is this maybe a problem on my config/system?)
until the expiration check happens, in the resume function that
actually kickstarts the lua task, making HAProxy think that expiration
time for the task is up, if I understand correctly tasks are meant to
never really timeout.
I'm attaching a tiny patch that fixes it for me, but seems rather
naive. It exploits the fact that hlua_timeout_task is set to
TICK_ETERNITY, which might or might not be an okay assumption to make
moving forward.
