RE: [Wikitech-l] PostgreSQL support in beta

Hey, > I'm trying out the 1.4beta1 release with PostgreSQL. Is it simple to persuade it to use PostgreSQL, or should I wait until the installer supports it? Mhm, last time I did that it was loading the schema and setting database type. There could be other issues as well, I'm trying to document them all up. Though, installer support might solve all bits. That's what installers are for :) Anyway, as far as I've heard, there are at least two mw-pg installs, one of which runs on my http://ph3.defau.lt/ Domas

1.4 category image thumbs
by Magnus Manske 10 Dec '04

10 Dec '04

While I really like the thumbnail preview of images on the category pages, I wonder what will happen on pages like [1] once 1.4 goes live on wikipedia. Will anyone without a T3 line be able to access such a page? I am already having problems with viewing [2]...

MediaWiki 1.4beta2 released
by Brion Vibber 10 Dec '04

10 Dec '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 MediaWiki 1.4beta2 is an experimental release, to help flush out remaining major problems in the code prior to a final public 1.4.0 release. It is not recommended to use this beta on a public site unless you're familiar with MediaWiki innards and are willing and able to help diagnose and fix problems that come up. All beta1 users should upgrade as soon as possible. This release fixes separate input validation issues with image gallery rendering and PostgreSQL. Other fixes include Recentchanges in PHP5, whitelist-edit mode, table prefixes, page renaming, and other issues. Additionally, startup time for cached page views is slightly faster.

Re: [Wikitech-l] status of MathML support

This is really the issue. MathML is natively supported in the Mozilla/Firefox/Netscape codebase for valid XHTML documents. MathML is supported in IE via MathPlayer for valid XHTML document. As I noted in my original post, as a side effect, MathML is also supported in IE for non-valid XHTML and HTML documents too. But I see tell that is of no interest to some of you at least, so I won't labor the point. So, the real obstacle to MathML in the wiki is that it can't guarantee valid XHTML. Checkmate. It would be nice to move forward with MathML support to gain the benefits of reuse in CAS systems, accessibility, searchability, and better rendering. But if you can't, you can't.

Right. This was the thrust of the August thread as well. > Does the MathPlayer work with directly embedded code, or does it > require some sort of plug-in-style usage? It works with directly embedded MathML. Actually for this application, the situation is pretty good. MathPlayer sniffs all incoming documents with the application/xml+xhtml MIME type and looks for a DOCTYPE declaration mentioning MathML. If it finds it, it filters the incoming document, adding a declaration to the document header to load MathPlayer and bind it to the MathML namespace. Also, since IE doesn't display XML directly, it changes the MIME type back to text/html, which "tricks" IE into displaying the document as HTML. In practical terms, what this means is a sloppy XHTML page with embedded MathML will generally display okay in IE. Of course it still crashes in Mozilla/Netscape/Firefox. I take it there is currently no convenient content negotiate mechanism in MediaWiki so one could serve MathML embedded in (X)HTML to IE, and HTML with PNGs to other browsers? When MathPlayer is installed in IE, it modifies the user agent string so it is easy to detect. --Robert ------------------------------------------------------------------ Dr. Robert Miner RobertM(a)dessci.com W3C Math Interest Group Co-Chair 651-223-2883 Design Science, Inc.

PostgreSQL support in beta

Hi - I'm trying out the 1.4beta1 release with PostgreSQL. Is it simple to persuade it to use PostgreSQL, or should I wait until the installer supports it? Thanks Jeremy

Debugging suggestions?
by Nick Triantos 09 Dec '04

09 Dec '04

I've got a strange problem on my installation of mediawiki (an extra blank line is emitted as the first line of all pages from my site). This apparently breaks the RSS feeds. Can anyone suggest a good way to debug where this newline is coming from? I was hoping I can run index.php from the cmd-line, and then at least be able to figure out what's happening here. Interestingly, I made a second copy of the wiki software in which I've been hacking in trying to debug this, and there, I see my shell prompt as the first line of text. So, something's pretty obviously shelling out during init, but I've currently got no idea what is doing that. thanks, -Nick

status of MathML support
by Robert Miner 08 Dec '04

08 Dec '04

Hello, I saw a thread from last August on the status of MathML support, and am writing to inquire if there has been any activity since. As co-chair of the W3C Math Interest Group, an editor of the MathML spec, and one of the authors of the MathPlayer plug-in for Internet Explorer, I am interested in doing what I can to help. --Robert ------------------------------------------------------------------ Dr. Robert Miner RobertM(a)dessci.com W3C Math Interest Group Co-Chair 651-223-2883 Design Science, Inc.

Hi There is a first Wikipedia Editor Eclipse Plugin available in the PHPeclipse CVS: http://phpeclipse.de/tiki-index.php?page=Wikipedia+Editor+Plugin Very buggy at the moment, but the principles for documenting a PHP project with some additional Wikipedia texts should work. A.C.Kramer
