I updated the documentation for setting up a MYSQL (MariaDB) database for
recording MIDAS history: https://midas.triumf.ca/MidasWiki/index.php/History_System#Write_MYSQL-history_events
One thing to note: the "writer" user must have the "INDEX" permission, otherwise
many things will not work correctly.
Included are the instructions for importing exiting *.hst history files into the
SQL database: mh2sql --mysql mysql_writer.txt *.hst
Let me know if there is interest in adding support for writing into Postgres SQL
database. We used to support both MySQL and Postgres through the ODBC library,
but in the new code, each database has to be supported through it's native API.
There is code for SQLITE, MYSQL, but no code for Postgres, although it is not too
hard to add.
