Since moving to MediaWiki 1.18, several of our extensions that use namespaces
have broken in the following way. Any advice/explanation would be very much
appreciated! (I don't see anything in the release notes.)
Some of our extensions contain logic like this:
if ($wgTitle->getNamespace() == NS_FOO) { .... }
The problem occurs when an article in the main namespace redirects to the Foo
namespace:
#REDIRECT [[Foo:Bar]]
When the user hits this redirect in 1.17 and earlier, the above test returned
True. In 1.18 it returns False, and I've had to replace it with more complex
logic to follow the redirect:
if ($wgTitle)
if ($wgTitle->getNamespace() == NS_FOO) {
// Really in the User namespace
$fooPageTitle = $wgTitle;
} elseif ($wgTitle->isRedirect()) {
$wikiPage = WikiPage::factory($wgTitle);
if ($wikiPage) {
$t = $wikiPage->getRedirectTarget();
if ($t && $t->getNamespace() == NS_FOO) {
$fooPageTitle = $t;
}
}
}
}
Am I doing something wrong, or is this a bug? What's the right way to detect
the namespace of a title, automatically following redirects, as used to work in
1.17?
Thanks,
DanB
