I've seen new commits that have been merged on the git repository.
The bad news are that the previous test that I reported (sending a
response larger than the buffer) doesn't work anymore :-/
Resulting in :
[ALERT] 067/220744 (27176) : Lua function 'hello_world': execution timeout.
Hi cyril,
This is due to the implementation of the Lua execution timeout. This is
a system used to prevent loops in scripts. The Timeout is set by
default to 4s. You can see "tune.lua.session-timeout",
"tune.lua.task-timeout" and "tune.lua.forced-yield"
http://cbonte.github.io/haproxy-dconv/snapshot/configuration-1.6.html#tune.lua.session-timeout
Of course, but it shouldn't take 4 seconds, the answer is immediate in
my test case.
Actually, I could find that it was reproducible beginning with a
response greater or equal to 16392 bytes (I've not read the code yet).
haproxy.cfg:
global
lua-load hello_world.lua
listen proxy
bind 127.0.0.1:10001
tcp-request content lua hello_world
hello_world.lua:
function hello_world(txn)
local res = txn:res_channel()
s = ""
for i = 1,16392 do
s = s .. "x"
end
res:send(s)
end
