Until now, we relied on setting MW_NO_SETUP which was a) hacky, b) irreversable, and c) likely to be forgotten if you didn't use one of the wrappers like runChild(). Instead, move the freaky magic to doMaintenance and have *it* check if it's in a specific call stack that indicates this is being run from the file scope and should be executed. Rename DO_MAINTENANCE to RUN_MAINTENANCE_IF_MAIN so it's nice and clear what magic happens behind the require_once().

/**
|
|
* Remove pages with only 1 revision from the MediaWiki namespace, without
|
|
* flooding recent changes, delete logs, etc.
|
|
* Irreversible (can't use standard undelete) and does not update link tables
|
|
*
|
|
* This is mainly useful to run before maintenance/update.php when upgrading
|
|
* to 1.9, to prevent flooding recent changes/deletion logs. It's intended
|
|
* to be conservative, so it's possible that a few entries will be left for
|
|
* deletion by the upgrade script. It's also possible that it hasn't been
|
|
* tested thouroughly enough, and will delete something it shouldn't; so
|
|
* back up your DB if there's anything in the MediaWiki that is important to
|
|
* you.
