Hello Karsten,

Hi Henning,
changing a parser without understanding the parser is dangerous. IMHO the [groupname] will be given to the mysql-libs.
I am not so deep inside kamailio c-code to full understand that case.

Hello,
just an idea – maybe the easiest way would be to introduce another character for the groups, e.g. ‘{ }’ or similar. The overlapping between IPv6 and groups was not intended, the group support is probably older as IPv6 in Kamailio. 😉
Cheers,
Henning

Hi Daniel,
you mean this commit (see below). Maybe Alexey Vasilyev can told us something to that change?
How can i use mysql-groups in the [] notation? Like:
#!define DBURL "mysql://[kamailio]/kamailio"
https://kamailio.org/docs/modules/5.3.x/modules/db_mysql.html#idm140
AFAIK this change splits [ and ] to ipv6 Host and sets ST_HOST6 and

db_mysql: database URL supports IPv6 address as hostname
- changed parsing of db_url to accept IPv6 address for hostname
Any help would be appreciated.
Cheers Karsten

Hello,
it could be that a patch to support ipv6 in the db url is conflicting with the syntax for the group name, because both seem to use [ ] . Iirc, such a commit was not long time ago. I will have to look at the code for mysql conf group to see what exactly it expects, not sure I got time for it today, though, maybe others can check quicker.
Cheers,
Daniel

Hi Daniel,
i create an Logfile with debug=3 on startup here: https://gist.github.com/khorsmann/91642daaa3715c59624cd5272bc3398a#file-logfile-txt-L4345
0(29174) DEBUG: db_mysql [km_my_con.c:108]: db_mysql_new_connection(): opening connection: mysql://xxxx:xxxx@kamailio/kamailio
I dont know where kamailio though that there is an "hostname" kamailio that holds the mysqldb/kamailio.
I want to use groups in the future - cos i auto-generate mysql-passwords with / for example and that is possible in groups, but i dunno how in normal defines.
Cheers
Karsten

Hello,
if you set debug=3, do you see any other log message that can give hints about the error?
I do not recall any change in using mysql conf groups, but there were some changes in supporting usernames with domains and few other updates that could have affected indirectly this part.
Cheers,
Daniel

Hi List,
i updated one of my testing kamailios from 5.2.x to latest 5.3.x.
After restarting the process, i got an mysql error that the server "kamailio" is not found.
I use the config-feature of my.cnf config-group names within the kamailio.cfg
I can start my kamailio 5.3.x installation with "normal username:password at host" definitions for DBURL.
Did anyone have the same issue?

from my kamailio.cfg i defined the DBURL like this:
# Use /etc/my.cnf.d/kamailio.cnf to store credentials
# within a mysql-db-group
#!define DBURL "mysql://[kamailio]/kamailio"
and special modules can use it like this (or via DBURL)
modparam("sqlops", "sqlcon", "cb=>mysql://[kamailio]/kamailio")
cat /etc/my.cnf.d/kamailio.cnf
