Description

Author: accnospamtom

Description:
Some providers use a hyphen as part of the databasenames (e.g. hosteurope.de).

Example: dbxxxx-yyyy

The "dbxxxx-" cannot be changed by the user, it's fixed.

The mediawiki installation script breaks with an error (invalid database name).

In my case, an older mediawiki-database exists, but cannot be upgraded with the new installer, clean install won't work either.

Version: 1.17.x

the regexp in "/includes/installer/MysqlInstaller.php"

line 79: <code>} elseif ( !preg_match( '/^[a-zA-Z0-9_]+$/', $newValues['wgDBname'] ) ) {</code>

should allow "-" as part of wgDMname

The error message would also need to be changed. So really need to check and see whether Postgres will also allow that character

Fixed in r79767.
