Hi all,
I've received a recent report that the "direct input" interface to
the feed validator at http://validator.w3.org/feed/, which uses the
rawdata feature of the feedvalidator, was failing for a number of
atom feeds, but working just fine with other types of feed.
Steps to reproduce:
1) go to http://validator.w3.org/feed/
2) paste in the "direct input" box the content of an atom feed, e.g
3) Submit the form
Result: validation fails, no error given
Note that the service is using the latest svn code (as of Aug 18,
2006), but the problem has been present at least since the last
codebase sync, at the end of July.
I have managed to tweak check.cgi a little to get a full trace of the
problem (attached).
The trace, to my untrained eye, does not seem to reveal anything
particular other than the involvement of a few libraries other than
the feedvalidator itself.
My suspicion of a library incompatibility is further justified by the
fact that my test service, running the exact same code for the
feedvalidator but on an unstable debian distribution, returns
(almost) correct validation results.
(check by going to http://qa-dev.w3.org/feed/ and reproducing steps
2, 3)
Any idea what could be causing this issue? I believe that the "direct
input" validation, however flawed (the document location and most
relative links obviously get screwed), is useful, and I'd like to
continue providing it.
Thanks.
