Change subject: User::saveOptions() optimization
......................................................................
User::saveOptions() optimization
Since we only want to save non default user options, we have to strip
out any user option that match the default ones. We did that by calling
User::getDefaultOption( 'some option name' ); on each of the option.
Since the User mOptions property is a merge of the default option, we
end up doing a lot of unneeded processing. The loop roughly looks like:
User::getDefaultOption()
User::getDefaultOptions()
Language->getCode()
SearchEngine::searchableNamespaces()
language->getNamespaces()
wfRunHooks('SearcheableNamespaces')
wfRunHooks('UserGetDefaultOptions')
For EACH of the mOptions.
Instead this patch does an array_diff to strip out from mObjects any
default option. We still skip options whose value is false or null.
Test provided to make sure we only save what we want.
