How to do 2 queries in one
by richardcavell＠mail.com 13 Mar '11

13 Mar '11

Hi everyone. I'm building a Wikipedia bot. My bot finds out the timestamp and author of the current version of a page in one query, like this : http://en.wikipedia.org/w/api.php?action=query&prop=revisions&format=xml&ti… If there is vandalism on the page, it attempts to find out the revid and name of the author of the previous author of the page, like this : http://en.wikipedia.org/w/api.php?action=query&prop=revisions&format=xml&rv… If there is no other author other than the current author, then it will not give a result. Note that the previous author may be 1 or 10 revisions ago - it simply means the person who edited it most recently other than the current author. Now, is there a way for me to combine these queries into one? That is, can I get the present author of the page and the previous author in one call, knowing that the present author may be responsible for 1 or several revisions, and that there may be no previous author ?

Determine whether current user can edit specified page
by Jim Safley 08 Mar '11

08 Mar '11

Hello, Using the API, what is the best way to determine whether the current user can edit a specified page? I could use: ?action=query&prop=info&intoken=edit&titles={title} to detect an "Action 'edit' is not allowed for the current user" warning, but this doesn't account for users with edit rights who attempt to edit a protected page. Thanks, Jim

BREAKING CHANGE: list=filearchive filtering parameters removed
by Bryan Tong Minh 07 Mar '11

07 Mar '11

In r83410/r83411 I have disabled filtering by size (faminsize/famaxsize) and by hash (fasha1/fasha1base36) for list=filearchive because of performance problems. It is possible that filtering by hash will return at a later point, but filtering by size has gone for good. Affected wikis are those that run on version 1.17. This includes Wikimedia, to which this change will be deployed this week. Best regards, Bryan Tong Minh

Trying to get a past revision of a page
by richardcavell＠mail.com 07 Mar '11

07 Mar '11

Hi everyone. I'm trying to code a Wikipedia bot. The bot is going to look at past revisions of a page to check whether vandalism was present in past revisions. I can get the unmodified wikitext of a page using: http://en.wikipedia.org/w/index.php?action=raw&title=User:Richardcavell But that only works for the most recent revision. Using prop=revisions I can get the revid of a past revision. Then if I try: http://en.wikipedia.org/w/index.php?action=raw&revids=342742660 It gives me the main page, not the past revision of User:Richardcavell. Doing: http://en.wikipedia.org/w/index.php?action=raw&revids=342742660&titles=User… doesn't work. It still gives me the main page. If I do: http://en.wikipedia.org/w/api.php?action=query&format=xml&prop=revisions&rv… then I get the past revision. It is surrounded by XML tags, and some of the text is changed. For example, " is replaced by ". Removing the XML tags isn't so difficult, but is prone to error. The second issue is more annoying. 1. Is it possible for me to get the raw wikitext of a past revision, without XML tags? 2. Is it possible for me to get the raw wikitext without the "->" style modifications? Richard

How to get past revisions of a page
by richardcavell＠mail.com 05 Mar '11

05 Mar '11

Hi, everyone. I'm coding a Wikipedia bot. The MediaWiki API documentation isn't helping me much. I'd like to know: I want to download the most recent version of a page that was written by an author other than the author of the most recent version. (ie what it looked like before the current author). I want to compare versions, so that if vandalism has occurred in the most recent author's version but not the previous author's version, my bot can rollback. Presently my body downloads the wikitext of the page using index.php rather than api.php. How do I download the wikitext of the previous version ? Richard

Understanding MediaWiki error codes
by richardcavell＠mail.com 04 Mar '11

04 Mar '11

Hi everyone. I'm trying to code a wikipedia bot, building the framework myself. I want to understand how to interpret the results of a request to the Edit MediaWiki API. So far my code does this : Interpret HTTP status code. if it's 503, sleep then try again if it's 504, sleep then try again if it's not 200, abort giving an error code Test for an API Error if it's maxlag, sleep then try again if it's editconflict, restart the whole test-edit sequence if it's success, return success abort, giving an error code 1. Are there any common replies that I am not accounting for with the above code? 2. How do I best test for an API Error? Should I search the header for "MediaWiki-API-Error:" and use the rest of the string as the code? Or should I test the body? I'm working in XML. 3. Similarly, how do I best test for success? TIA, Richard

API: Edit
by richardcavell＠mail.com 03 Mar '11

03 Mar '11

Hi everyone. Looking at this page: http://www.mediawiki.org/wiki/API:Edit There are many parameters that can be set when sending an HTTP POST with the intention of doing an edit. Do all of the parameters go in the URL? Can I shift some of them into the HTTP POST in the body of the request? In particular, where does the new text go? Does that go as a form item in the body of the request? Richard

Edit tokens
by richardcavell＠mail.com 03 Mar '11

03 Mar '11

Hi all. I'm coding a Wikipedia bot framework (not using any existing framework) for use on en-wiki. I'm a little confused by the documentation of edit tokens. Which is the correct approach: 1. My bot obtains an edit token using the Main page as a nominal title, saves the edit token and then uses it in every subsequent attempt to edit. or 2. My bot queries each page to obtain an edit token before attempting to edit. Richard (TIA)
