cc thedj, he did something with SVG metadata, I believe.

In commons "This image rendered as PNG in other sizes: 200px, 500px, 1000px, 2000px." not work

Onclick event at Download link for a SVG image show:

Error: http://commons.wikimedia.org/w/index.php?title=MediaWiki:Stockphoto.js&action=raw&ctype=text/javascript at line 179: thumb_url is undefined

Error: http://commons.wikimedia.org/w/index.php?title=MediaWiki:Stockphoto.js&action=raw&ctype=text/javascript at line 179: thumb_url is undefined

Several SVGs at Commons report invalid tags while rendering (i.e. <a:midPointStop
 in http://upload.wikimedia.org/wikipedia/commons/b/b9/Gtk-media-play-ltr.svg ). Many of these are untouched for some years already.

that doesn't mean that the SVGs are necessarily ok. just that we were more lenient in the past.


For the first one:

SvgHandler::getMetadata: Expected <svg> tag, got svg:svg
File::getPropsFromPath: /Users/hartman/Development/phase3/images/4/44/QA_icon_own_version.svg loaded, 11021 bytes, image/svg+xml.
LocalFile::upgradeRow: upgrading QA_icon_own_version.svg to the current schema
DatabaseBase::query: Writes done: UPDATE  `image` SET img_width = '0',img_height = '0',img_bits = '0',img_media_type = 'DRAWING',img_major_mime = 'image',img_minor_mime = 'svg+xml',img_metadata = '0',img_sha1 = 'dr2uqjc96l4dzt8jkgw5997pa9098jj' WHERE img_name = 'QA_icon_own_version.svg'
Class SkinVector not found; skipped loading

That seems like a fixable bug. i'll make a patch.

*** Bug 27359 has been marked as a duplicate of this bug. ***

Fixed in r82307

The problem is not fixed. See "Archivo:QA icon.svg" in http://es.wikipedia.org/wiki/Wikipedia:Portada

bug is fixed in r82307, and es.wiki has r82223 now - that's the reason, I think.

This needs to go to the production server as soon as possible. You have a date?

Probably whenever this is pushed it out.  Since we just completed the push of 117wmf1, I'm not sure when that will be.  I'll make sure this is done then, though.

(Adding Roan, who knows more about pushes than I do and may have something to add.)

Problem fixed. Thanks

r82307 does not fix the problem correctly, and still breaks on files such as https://secure.wikimedia.org/wikipedia/en/wiki/File:US_states_by_total_state_tax_revenue.svg

The fix appeared to simply make the assumption that the SVG namespace will either be the unlabeled root namespace or will be given the symbolic name 'svg'; there is absolutely no such guarantee. The above file defines it as 'ns0', which is 100% legit to do, but it gets rejected.

Proper fix is probably to simply use a namespace-aware XML parsing mode. Use the namespace URL to check against, and let the XML tools worry about matching up prefixes.

Added test cases in r88865, including the file from comment 14 which currently fails, and the files from comment 1 and comment 4 which do work with the current code.

FAILURES!
Tests: 3, Assertions: 2, Errors: 1.

Trunk r88870 reverts the previous fix for a cleaner diff; r88871 commits a new fix that checks the localName & namespaceURI properties instead of checking for particular prefixes in the combined name.

Seems to work ok with the test cases I added earlier and the Wikimedia logo SVG which doesn't use a namespace; also made a slight tweak to metadata extraction (eg RDF) to trim whitespace.

We should add test cases for animation and any other property that can be extracted as well, but that's for another story.

Will need merge to 1.17, 1.17-wmf & 1.18.
