I thought I recorded this bug already can't find it. This behavior was okay up until 1.18 and since 1.19wmf1 was deployed, it is breaking. == Steps to reproduce == * When logged out, visit a url to an existing view but without a title query parameter, for example: - https://nl.wikipedia.org/?curid=2788608&redirect=no - https://en.wikipedia.org/?diff=123 * Click Login in the top left and continue the login procedure == Expected == The "Back to ..." link should go to where I was == Actual == The link says "Main page" and goes to /wiki/Main_Page, no query at all. I could understand if it assumes the title 'Main Page' if none was found in the originating url (although even that is somewhat unneeded, since MediaWiki knows the page title by the time the page is rendered, based on oldid and/or pageid). But instead of it becoming ?title=Some_page&originalquery or ?originalquery, it becomes /wiki/Main_Page.
*** Bug 38251 has been marked as a duplicate of this bug. ***
There are two separate reasons this bug occurs. The first is that if no title is specified, then SkinTemplate::buildPersonalUrls() will not put any returntoquery, even if there is a query to return to. This is easily fixable. The second issue is that LoginForm::successfulLogin() requires a returnto value in order to build the redirect URL. This is because it calls Title::getFullURL() on the returnto title. To get around this, there needs to be a way to build a full URL without having a valid title object.
no code yet, so pushing to future.
