BUG/MEDIUM: lua: Fix dumping of stick table entries for STD_T_DICT
The issue can easily be reproduced with "stick on" statement
backend BE_NAME
stick-table type ip size 1k
stick on src
and calling dump() method on BE_NAME stick table from Lua
Before the fix, HAProxy would return 500 and log something like
the following:
runtime error: attempt to index a string value from [C] method 'dump'
Where one would expect a Lua table like this:
{
["IP_ADDR"] = {
["server_id"] = 1,
["server_name"] = "srv1"
}
}
This patch needs to backported to 1.9 and later releases.
