* Don't show help if the first argument is "help", only show it if there is a "--help" option. That makes more sense for the scripts that accept filenames as parameters and is the backwards-compatible behaviour. * Renamed spawnChild() to runChild(), spawn implies creating a new process to run simultaneously with the old one * Removed error_reporting override, that's a matter for local policy * s/private/protected

/**

|
* 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.
