Also make it abstract in DatabaseBase so all subclasses have to implement some human readable name
(also make getSoftwareLink abstract for the same reason) Every current Database class already implements both.
Notably, this will switch conditional() in MySQL from using IF() to
using CASE, like all other DBMSes. Documentation suggests this works
back to 4.0. If it's a problem, it's a matter of a few lines to
override it in DatabaseMysql.php.
Also, some extra explanatory comments have been added to a number of
methods in DatabaseBase.
Specifically freeResult(), selectDB(), close(), and ping(), as suggested
by Tim on code review for r51918. Where these were overridden by stubs
in subclasses, I deleted the stubs.
All other databases were changed to extend DatabaseBase instead of
Database. Database was kept as an alias for DatabaseMysql for
compatibility. Existing explicit references to Database that I could
find were changed to DatabaseMysql for the sake of clarity.
Should cause no functional changes.
* renamed \2types and \3types both to \types (with different number of param), Doxygen doesn't seem to like numbers in aliases
* Added aliases for @private, @protected and @public
or Database::newFromParams() explicitly at the moment. While that's already bad (breaking PG support etc), I'd rather see those get fixed before we go introducing differences between Database and DatabaseMySql.
* Wrote a tool to check the integrity of the autoloader class list, fixed some issues that came up.
* Start the autoloader before LocalSettings.php, so that when an extension writer thinks an inefficient one-file special page extension is the way to go, they don't have to use explicit includes to make the class inheritance work. Should continue to work with $IP set in LocalSettings.php as long as $IP is set before extensions are included.
