I'm not going to introduce a new module for this, but some of the flags this module provides (external, readable, url, editurl) can be added as options to prop=info. The others (existence and redirect checking) are already done.

Changing bug title to reflect this.

How lightweight is prop=info? I was worried that the revision and length related values would be strong on the database (if this is intended to be called by another wiki on a theoretically large number of pages), and how lightweight this is on HTTP (if another wiki wanted to call it). Although with the combining of the pages, HTTP overhead would probably be less.

How lightweight is prop=info? I was worried that the revision and length
related values would be strong on the database (if this is intended to be
called by another wiki on a theoretically large number of pages), and how
lightweight this is on HTTP (if another wiki wanted to call it). Although with
the combining of the pages, HTTP overhead would probably be less.

Nothing in the API is hard on the database, because we're well aware of the fact someone could call any query repeatedly with up to 5000 titles. prop=info is one of the more lightweight modules as long as inprop=protection isn't set.

Added inprop=url and inprop=readable in r41261. The rest of the properties from the patch are already available:

• Non-existent pages have the 'missing' attribute
• Redirects have the 'redirect' attribute
• Interwiki titles (external) are in the <interwiki> element
