The error message on upload was wrong MIME type (in german). It took me two evenings to learn that the problem had to do with namespaces (i had given svn but failed to add xlink). The validator on the toolserver should be in line with the checks done on upload and the error message should be more informative.

https://bugzilla.wikimedia.org/show_bug.cgi?id=27544 --- Comment #18 from Brion Vibber br...@pobox.com 2011-02-21 18:18:05 UTC --- I got a little lost reading the backscroll here, but let me just summarize the expected behavior: * invalid[1] SVG file MUST be rejected on upload * invalid[1] SVG file that's already existing SHOULD be rejected from rendering, but if it does render it's not the end of the world. [1] by invalid I mean one or more of the following is true: * not well-formed XML (ie, any error is thrown by XML parser) * not well-formed namespaces (ie, an error is thrown by namespace-aware XML parser about inconsistent or undeclared namespaces) * root element isn't svg with expected namespace * anything in the file violates our generic or SVG-specific safety checks Non-rendering of broken files is not a bug; it's expected behavior. Affected files should be fixed. New files being uploaded that do not pass the validation checks *is* a bug, if it's happening. Failure to live through our XML/SVG-specific checks MUST NOT be overridden by some other generic check. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug.

The best way to fix this is to split the valid and wellformedness check. Wellformed but invalid XML should be marked application/xml. Unwellformed and invalid XML should never be marked application/xml or any XML subtype, even of if the PHP file info extension recognizes it as such. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug.

That would be a very easy way to do whitelist-based security, which makes me feel happier than the current blacklist-based approach. Are we really sure that all JS-activating attributes start with on, and that no element will allow script if it's not named script?

https://bugzilla.wikimedia.org/show_bug.cgi?id=27544 --- Comment #12 from Derk-Jan Hartman hart...@videolan.org 2011-02-19 16:22:58 UTC --- summary, on wmf servers, guessMimeType returns 'application/xml' instead of 'image/svg+xml'. guess mimetype calls doGuessMimeType(), which will call XmlTypeCheck() $xml = new XmlTypeCheck( 'http://bug-attachment.wikimedia.org/attachment.cgi?id=8170' ); var_dump( $xml-wellFormed ); shows the wmf servers as evaluating wellFormed to false. This is not correct btw, for most of these files, since most are only invalid but are wellformed, this is a bug in XmlTypeCheck(). Actually, on my own server it even always evaluates to false, but later parts apparently pick up the slack. MimeMagic::doGuessMimeType: analyzing head and tail of /private/var/tmp/phpwMVYQ7 for magic numbers. DjVuImage::getInfo: not a DjVu file MimeMagic::guessMimeType: internal type detection failed for /private/var/tmp/phpwMVYQ7 (.)...

Internal type detection failed, indicates that doGuessMimeType() has returned false and detectScript() takes over and selects image/svg+xml for me, but apparently not on the WMF installation. I guess in 1.16 something was correcting for this issue for wmf as well, but now no more... -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug.

I don't see any changes between 1.16 and 1.17 that would explain the difference. The bug is with XmlTypeCheck though. xml_parse() returns an error for both an invalid as an unwellformed document, whereas we only want an error on an unwellformed document. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug.

Hershberger m...@everybody.org 2011-02-19 17:41:42 UTC --- (In reply to comment #9) I'm not too familiar with XML, but does that mean that the DTD is fetched from w3.org every time an SVG file is viewed? No. The URIs in xmlns attributes are not meant to be resolved and fetched. Often, they can be, since the http schema is used and people DTD at that address. But it is only meant to serve as a unique identifier, not a resource to be retrieved. In practice, though, some (poorly written) validators do attempt to fetch the resource every time. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug.

https://bugzilla.wikimedia.org/show_bug.cgi?id=27544 --- Comment #16 from Bryan Tong Minh bryan.tongm...@gmail.com 2011-02-19 22:28:31 UTC --- To clarify, for people who have not followed the IRC discussion: * The original assumption that the non-rendering of certain SVGs was caused by the new SvgMetadataExtrator was false. * MimeMagic::doGuessMimeType uses XmlTypeCheck to detect the mime type; this fails because XmlTypeCheck::wellFormed is set to false when the SVG is non-validating instead of non-wellformed * For me and Derk-Jan, the fileinfo pecl extension then detects the file as image/svg+xml anyway, but at Wikimedia it is detected as application/xml XmlTypeCheck must be fixed to only check wellformedness. Additionally, it would be interesting why at Wikimedia there is a difference between 1.16 and 1.17. A suggested approach for fixing XmlTypeCheck would be to change xml_parse_create_ns() into xml_parse_create(), but somebody who understands Xml properly needs to look at that. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug.

The XML specification forbids compliant implementations from doing anything but failing spectacularly, and most decent XML parsers follow the rules.
