Gdk-ERROR **: The program 'sugar-activity' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.

  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line

   backtrace from your debugger if you break on the gdk_x_error() function.)

Solved in Wikipedia-30/WikipediaEN-30

Related to http://bugs.sugarlabs.org/ticket/3183

[godiard]

I have added two patches:

* One fix my mistake and use the requested size instead of 300px.

* The second request the thumbnails to images in galeries. (Can be tested in the page "Spain")

The code is working with images with special characters (Can be tested in the page "Coruña", the first image have special char in the name)

The only problem I could not solve was the case where there are a image smaller than the requested thumbnail size. I have found one case in the page "Planet", in the Orbit section.

A reference to the image parameters in wikipedia is here http://en.wikipedia.org/wiki/Wikipedia:Extended_image_syntax

Thanks for checking all that. I guess there is no easy solution for the planet issue.

Do you know of any pages that use a image of type "frame"? The Extended image syntax page suggests that you can't apply a size attribute to a framed image, which your work does, but after a very brief look I can't find any examples to test with.

Have you tested pages with SVG images? It looks like wikipedia will do thumbnails of svg images, but it will present them in PNG format (e.g. http://upload.wikimedia.org/wikipedia/en/thumb/c/ce/SVG-logo.svg/500px-SVG-logo.svg.png). Your patch will still use <object> to display them when actually it should be <img> right?

Also I can't quite grok the final hunk of your original commit, specifically this line: https://dev.laptop.org/git/projects/wikiserver/tree/server.py#n439

            self.out.write('<a href="%s">' % url_thumb.encode('utf8'))

What does that final 'else' condition represent, and is it definitely correct to use the thumbnail rather than the real image as the link target here?

Replying to dsd:

The Extended image syntax page suggests that you can't apply a size attribute to a framed image, which your work does, but after a very brief look I can't find any examples to test with.

There are few (34) images with type "frame" and a defined size. One is the first image in the page "Henry Ford". There are also images with type "frame" but without size, like in "2004 Indian Ocean Earthquake", the first animation in the section "Tsunami characteristics". Is logic do not have a size and is not scaled, because wikipedia does not scale animated gifs. Both cases are well displayed.

Have you tested pages with SVG images? It looks like wikipedia will do thumbnails of svg images, but it will present them in PNG format (e.g. http://upload.wikimedia.org/wikipedia/en/thumb/c/ce/SVG-logo.svg/500px-SVG-logo.svg.png). Your patch will still use <object> to display them when actually it should be <img> right?

The original code (and my patch) exclude the svg images, because in more cases the svg image will be smaller than the resulting png. The SVG are ok, and you can see it in the Planet page, in the "Orbit" section (just over the missing little image). Another example is the first image in "Olympic Games" page.

Also I can't quite grok the final hunk of your original commit, specifically this line: https://dev.laptop.org/git/projects/wikiserver/tree/server.py#n439 {{{ self.out.write('<a href="%s">' % url_thumb.encode('utf8')) }}} What does that final 'else' condition represent, and is it definitely correct to use the thumbnail rather than the real image as the link target here?

It's true. This is a link then, does not have sense change it. I don't know in what conditions the else part can be executed, but was present in the code.

OK great, sounds like all the questionable cases are covered then (svg, frame, special characters) with the only small issue being tiny images, which are not common. It is looking good indeed.

I don't understand your comment about the final else clause. Your patch does change the original code behaviour, from linking to the original image, to linking to the thumbnail, and it's the only part of the patch I don't understand.

fixed in wikipediaES-31 and wikipediaEN-31, thanks gonzalo!
