TYPO3 Core

The install tool doesn't seem to recognize/use the mysqli extension when mysql is not installed.

Shouldn't the dbal cover that? - if so dbal needs better docs.

Either support directly mysqli or some kind of documentation needs to say typo3 doesn't support it and that mysql is required, or make dbal work better.

The install tool explicitly checks for the mysql extension:

if (!extension_loaded('mysql') && !t3lib_extMgm::isLoaded('dbal'))

If I get a chance, I'll look into dbal and figure out how to patch what, or what documentation needs to be clarified, but until then, I'm sure no one would be dissapointed if someone took this on.
