can set "zero-warning" option to prevent abuse by Lua scripts or to
prevent bugs.
For your use case, maybe you could use maps from Lua? They should be
backed by ebtree and be faster right?

If you use Lua for action or service (i.e. you have txn object readily
available in the script), you can use txn:set_var(name, value) to
communicate stuff back to regular HAProxy layer, and then log the value
of the variable with rest of the stuff.

Hi guys,
While playing with Lua API I've noticed that core.proxies attribute
doesn't return all the proxies, more precisely the ones with same names
(e.g. for frontend and backend with the same name it would only return
the latter one).

I've noticed that a Lua service timeouts in DATA phase, for outputs

After the timeout (timeout client), it returns the full response.

problem. You mig

Hello guys,
Here is a fix for bug in
hlua_server_check_enable()/hlua_server_check_disable, the bitwise logic
in the code was inverted.
This can be applied to 1.7 too.

Here is me doing my best, selling you the good stuff, and the reason to

I was under impression that we only have to acquire lock and increment
ref_cnt (so we can be sure our current node n is not deleted)

P.S.
Lua usually suffers trying to do things in tasks, I don't think this is
the first time something gets broken. Can we make reg test with Lua
script (maybe strip out LuaSocket requirement)?
