Hi Otto, From IRC (#debian-mysql) on 28 September:
[21:42:11] <elbrus> ottok: dbconfig-common parses /etc/mysql/debian.cnf [21:42:22] <elbrus> did the content of that file change? [21:42:36] <elbrus> I'm now only seeing this in my unstable lxc [21:42:46] <elbrus> # Automatically generated for Debian scripts. DO NOT TOUCH! [21:43:04] <elbrus> shouldn't there be some root set (with password)? [21:44:28] <elbrus> at least it seems to me that the test fails due to this empty config file [21:44:44] -*- elbrus is generating a testing lxc to check [22:12:17] <Skuggen> I think both mysql and mariadb have moved away from root password as default, and instead use unix socket authentication [22:12:54] <Skuggen> So system root can log in without a password [22:20:49] <elbrus> # cat /etc/mysql/debian.cnf [22:20:49] <elbrus> # Automatically generated for Debian scripts. DO NOT TOUCH! [22:20:49] <elbrus> [client] [22:20:49] <elbrus> host = localhost [22:20:49] <elbrus> user = root [22:20:49] <elbrus> password = [22:20:49] <elbrus> socket = /var/run/mysqld/mysqld.sock [22:20:49] <elbrus> [mysql_upgrade] [22:20:49] <elbrus> host = localhost [22:20:49] <elbrus> user = root [22:20:49] <elbrus> password = [22:20:49] <elbrus> socket = /var/run/mysqld/mysqld.sock [22:21:28] <elbrus> but in the current implementation dbconfig-common still processes the file (at least in the test) [22:21:48] <elbrus> I'll check tomorrow if the production code does so too [22:27:10] <elbrus> well, at least https://salsa.debian.org/debian/dbconfig-common/-/commit/252b921f6a6a50e6d98d1c11bb71f2810d7f2278 is still in place [22:27:14] <elbrus> so that needs updating [22:27:55] <elbrus> which means that MariaDB in unstable broke packages that need dbconfig-common to install [22:28:19] <elbrus> not saying MariaDB needs to fix it, but it shouldn't migrate to testing as-is So, the summary is that dbconfig-common as it currently is relies on /etc/mysql/debian.cnf to contain at least the username for connecting (and the password for systems that don't do socket authentication): # Now we are pretty sure we can use the password # Command taken from mysql-server-5.5.postinst script dbc_dbadmpass="$(sed -n 's/^[ ]*password *= *// p' /etc/mysql/debian.cnf | head -n 1)" # We also want to obtain the dbc_dbadmin from this file as MySQL has # debian-sys-maint, but MariaDB may have root. dbc_dbadmin="$(sed -n 's/^[ ]*user *= *// p' /etc/mysql/debian.cnf | head -n 1)" I implemented this after a discussion I had with you at FOSDEM some years ago. What's the proposal I do now? Paul
