Here is a diff to make attempt #2 at switching to MariaDB.
Going through the various Makefile's I noticed bmf had a typo
with its WANTLIB entry for MySQL.
It seems that files moved between -server (on mysql) and -client (on mariadb),
/usr/local/bin/msql2mysql (mysql-server-5.1.73p0v0 and
mariadb-client-10.0.13)
/usr/local/bin/mysql_find_rows (mysql-server-5.1.73p0v0 and
mariadb-client-10.0.13)
/usr/local/bin/mysql_waitpid (mysql-server-5.1.73p0v0 and
mariadb-client-10.0.13)
/usr/local/bin/mysqlaccess (mysql-server-5.1.73p0v0 and
mariadb-client-10.0.13)
/usr/local/man/cat1/msql2mysql.0 (mysql-server-5.1.73p0v0 and
mariadb-client-10.0.13)
/usr/local/man/cat1/mysql_find_rows.0 (mysql-server-5.1.73p0v0 and
mariadb-client-10.0.13)
/usr/local/man/cat1/mysql_waitpid.0 (mysql-server-5.1.73p0v0 and
mariadb-client-10.0.13)
/usr/local/man/cat1/mysqlaccess.0 (mysql-server-5.1.73p0v0 and
mariadb-client-10.0.13)
untested but perhaps adding "@conflict mysql-server-*" to mariadb/pkg/PLIST-main
will let this update automatically..
Not specific to mariadb (similar things happen with the standalone mytop)
but noticed this while testing:
heh. you're right. If I run mytop numerous times it varies between
what you have below and just...
$ mytop
Segmentation fault (core dumped)
$ mytop
Cannot connect to MySQL server. Please check the:
* database you specified "test" (default is "test")
* username you specified "root" (default is "root")
* password you specified "" (default is "")
* hostname you specified "localhost" (default is "localhost")
* port you specified "3306" (default is 3306)
* socket you specified "/var/run/mysql/mysql.sock" (default is "")
The options my be specified on the command-line or in a ~/.mytop
config file. See the manual (perldoc mytop) for details.
Here's the exact error from DBI. It might help you debug:
