Self reference doesn't match document location

Brujo · Posted: Sat Apr 12, 2008 6:44 am

i checked the ATOM feed with the validator & shortlinks enabled and get then "Self reference doesn't match document location". With shortlinks disabled the feed is valid.

Example:

Only registered users can see links on this board!
Get registered or login to the forums!

Validator Output:
<link rel="self" type="application/atom+xml" href="http://www.my.domain/feeds.html&fid=11&type=ATOM" />

another Question is with the RSS2.0 Feed if i check it i get

Quote:

Example:

Only registered users can see links on this board!
Get registered or login to the forums!

Validator Output:
Missing atom:link with rel="self"

and the last Question is about the author section in Atom feeds,

Only registered users can see links on this board!
Get registered or login to the forums!

do i have to change this and if so, where?

thanks Brujo

We may need to build some logic into nukeFEED to address shortlinks, but I'm not sure when that will happen.

Not sure why the validator would give a message regarding ATOM for an RSS 2.0 feed. Does that happen with shortlinks off?

Regarding the author section, I'd suggest that changing that would open the door for spam. I believe it's only there for validation, but I haven't tested not using it, either.

Brujo/kguske,

I will look into the ShortLinks aspect of this. I have this working - I think - on my sites so I want to understand better as to what is going on there. I may be able to fix.

This is RavenNuke 2.20.x right?

@montego - i have rn 2.20.01
if you take a look, i think in nukeFEED.php the $syndicationURL have to be different if shortlinks is enabled

@kguske - missing atom: is independent from shortlinks
i checked it with

Only registered users can see links on this board!

& validator.w3.org/feed/ with the same result that indeed the feed is valid but with this recomendation

Quote:

This feed is valid, but interoperability with the widest range of feed readers could be improved by implementing the following recommendations. line xy, column 4: Missing atom:link with rel="self"

and i found this:

Only registered users can see links on this board!

btw i did a look to backend.php

Code:

if (isset($tnsl_bUseShortLinks) && $tnsl_bUseShortLinks) {
header('Location: http://'.$host.$uri.'/feeds-1-rss20.xml');
} else {
header('Location: http://'.$host.$uri.'/modules.php?name=Feeds&fid=1&type=RSS20');
}

this code assume that fid=1 is existing and that nobody deleted this feed like i did in the feed module Very Happy

for my OK i fixed that, but as an Idea, Users should not be able to delete Feed 1 or the backend is gone..

Brujo, btw, I am looking at the ShortLinks issue now and I am pretty sure that I can fix the validation error. It is definitely in the "link rel" at the top.

It does not seem to impact the usability of the feed, but it does affect its validation. I'll let you know what I come up with.

Ok, it turns out to have been an inconsistency in the use of ATOM1.0 vs ATOM. Here is the fix:

=== OPEN ===

ShortLinks/GT-Feeds.php

=== REPLACE ===

Replace the entire $urlin/$urlout with the following:

Code:

$urlin = array(
'"modules.php\?name=Feeds&fid=([0-9]*)&type=HTML"',
'"modules.php\?name=Feeds&fid=([0-9]*)&type=RSS([0-9]{1})\.([0-9]{1,2})"',
'"modules.php\?name=Feeds&fid=([0-9]*)&type=ATOM([0-9]{1})\.([0-9]{1,2})"',
'"modules.php\?name=Feeds&fid=([0-9]*)&type=ATOM"',
'"modules.php\?name=Feeds&op=map&type=OPML"',
'"modules.php\?name=Forums&file=viewtopic&t=([0-9]*)"',
'"modules.php\?name=News&file=article&sid=([0-9]*)"',
'"modules.php\?name=Downloads&op=getit&lid=([0-9]*)"',
'"modules.php\?name=Downloads&d_op=getit&lid=([0-9]*)"', // <-- For NSN GR Downloads
'"modules.php\?name=Content&pa=showpage&pid=([0-9]*)"',
'"modules.php\?name=Web_Links&l_op=viewlinkdetails&lid=([0-9]*)"',
'"modules.php\?name=Feeds"'
);

$urlout = array(
'feeds-\\1.html',
'feeds-\\1-rss\\2\\3.xml',
'feeds-\\1-atom\\2\\3.xml',
'feeds-\\1-atom10.xml',
'feeds-map-opml.xml',
'ftopict-\\1.html',
'article\\1.html',
'download-file-\\1.html',
'download-file-\\1.html', // <-- For NSN GR Downloads
'content-\\1.html',
'viewlinkdetails-\\1.html',
'feeds.html'
);

=== FINISH ===

The Atom feed now validates on my own site with this change.

kguske, it was a difference in the use of atom version number being missing in the link rel statement at the top. You use ATOM1.0 in most other places except at the top.

@montego
perfect, works also for me no more validation issue with ATOM

btw. have someone a idea for the RSS recomendation "This feed is valid, but interoperability with the widest range of feed readers could be improved by implementing the following recommendations. line xy, column 4: Missing atom:link with rel="self"

Thanks, Brujo. I'll take a look.
