259777 - RSS feeds which never finish verifying

Status: RESOLVED FIXED

(MailNews Core :: Feed Reader, defect)

Description

[Henrik Gemal]

I cant seem to add the rss feed:
http://www.computerworld.dk/rss.asp

it just keeps saying "verifying the feed..."

using latest nightly branch build

Comment 1

[Ben]

If you are behind a firewall: Do you have the proxy configured in Thunderbird?

Comment 2

[Michael Barrientos]

Another feed where it gets stuck on "verifying the feed...":
http://bensbargains.net/rss.xml

Using Thunderbird 0.8 (not a nightly). Not behind any firewall and not using any
proxy.

Comment 3

[Christopher Currie]

Another problem feed:

http://www.studiofoglio.com/atom.xml

Also not using a proxy.

Comment 4

[Bryn Keller]

Another problem feed (version 0.8, not a nightly):

http://www.xoltar.org/rss.xml

No proxy, and feed is valid according to 

http://feedvalidator.org/check?url=http://www.xoltar.org/rss.xml

Comment 5

[Henry Goffin]

This happenens whenever a feed's data file is left around after unsubscribing.

A workaround is to exit Thunderbird, delete the offending feed file from your
profile/Mail/News&Blogs folder, and restart Thunderbird.  You can then subscribe
again.

Comment 6

[Henry Goffin]

... please disregard comment 5, that appears to be another bug with the same
symptoms.  I can confirm that the urls given here do not work with a brand new
profile directory.

Attachment: Good moinmoin RSS feed.

An example RSS feed that Thunderbird CAN subscribe to.	It is valid (see
http://rss.scripting.com/), and the only difference is I changed 

<rdf:RDF xmlns:None="http://purl.org/rs...etc

to

<rdf:RDF xmlns="http://purl.org/rs...etc

Attachment: Bad moinmoin RSS feed.

An example RSS feed that Thunderbird CANNOT subscribe to.  It is valid (see
http://rss.scripting.com/), and the only difference is I changed 

<rdf:RDF xmlns:None="http://purl.org/rs...etc

to

<rdf:RDF xmlns="http://purl.org/rs...etc

Comment 9

[elegant_dice]

See attachments.

I cannot subscribe to RSS feed
http://moinmoin.wikiwikiweb.de/RecentChanges?action=rss_rc
even though it is valid
http://rss.scripting.com/?url=http%3A%2F%2Fmoinmoin.wikiwikiweb.de%2FRecentChanges%3Faction%3Drss_rc

It seems to be because Mozilla chokes on xmlns:None= (see attachments).
Thunderbird has no problems after removing ':None' in the moinmoin RSS feed
(used wget and vi, put the file on my own website and subscribed to it).

Using version 0.8 (20040926) on standard debian.  Confirmed by GentooBSD on
#mozillazine.

Add GoogleBlog to the list of problem feeds

Comment 11

[Marcia Knous [:marcia]]

modifying this since there are quite a few bugs which reported this. we can add
rss links here which exhibit the verifying-never-finishes issue.

Comment 13

[Marcia Knous [:marcia]]

not sure if these rss have something in common which causes this bug, of it's
different issues?

tentatively nominating --esp if it might be due to a common issue.

Comment 17

Comment on attachment 166399 [details] [diff] [review]
fix for http://www.studiofoglio.com/atom.xml

this feed had empty content inside of the author tag. The code had a bug in
that case where this.author got set to the actual DOM NODE for the author
instead of a string. This led to a JS exception down the line.

Comment 18

[Scott MacGregor]

http://www.computerworld.dk/rss.asp is now working in the latest nightlies for me.
Cross that one off the list.

Comment 19

[Scott MacGregor]

Attachment: fix for several of the sites

This patch fixes: 

http://www.studiofoglio.com/atom.xml 

this feed had empty content inside of the author tag. The code had a bug in
that case where this.author got set to the actual DOM NODE for the author
instead of a string. This led to a JS exception down the line. 

It also now fixes:
http://bensbargains.net/rss.xml
http://www.google.com/googleblog/atom.xml

which were atom feeds where we weren't handling an empty items tag properly. We
were throwing a JS error instead of hitting fallback code which was already
there to address this issue.

Comment 20

[Scott MacGregor]

the patch referenced in comment #19 has been checked into the trunk and the branch

Comment 21

[nicolas chevreux]

I am having this bug for the first time, with feeds that used to work properly
(that I had to delete and re-suscribe to). I am using neither a proxy nor a
firewall.
Win XP Pro SP1, TB 0.9 Build 2004-11-25.

Comment 22

[sairuh (rarely reading bugmail)]

all of the feeds referenced in this bug now verify *except* for the following:

a. attachment 163385 [details] "bad moinmoin rss feed" --is this still a valid test?

b. http://littlegreenfootballs.com/weblog/weblog.rss --this was bug 269506:
should that bug be reopened rather than this one?

tested with 2004112705-0.9 on linux fc2.

Comment 23

[Steffen Wilberg]

Using my self-compiled 1.0RC1RC1 (that's what it says in the about box), I still
see this with
http://weblogs.mozillazine.org/asa/index.rdf
http://weblogs.mozillazine.org/asa/atom.xml
http://www.vlad1.com/~vladimir/blog/feed/rss2/
http://www.steelgryphon.com/blog/wp-rss2.php

With the first two, the progress indicator runs from 0% to 100%, but stays there.
With the latter two, that indicator stays at 0%.

Comment 24

[Steffen Wilberg]

The upper three feeds I mentioned in comment 23 display this error in the js
console:
Error: [Exception... "Component returned failure code: 0x8055000b
[nsIMsgFolder.createSubfolder]"  nsresult: "0x8055000b (<unknown>)"  location:
"JS frame :: chrome://messenger-newsblog/content/FeedItem.js :: anonymous ::
line 169"  data: no]
Source File: chrome://messenger-newsblog/content/FeedItem.js
Line: 169

The last one now verifies, but the only item displays a "Try again" link, which
leads to this error page in Firefox:
"The file /mnt/daten/Sonstiges/Thunderbird/Steffen/Mail/News & Blogs/Zarro Boogs
found. ?number=0 cannot be found. Please check the location and try again.#"

Comment 25

[Scott MacGregor]

intersting...all 4 of those feeds load and verify correctly for me on Windows
using todays build. 

Comment 26

[Steffen Wilberg]

Adding other feeds, like http://www.mozilla.org/news.rdf, works fine. There are
no leftovers from those "broken" feeds in my News & Blogs folder. Renaming
feeds.rdf doesn't help either.

This has to be related to the location of my News & Blogs folder. I have no
problems with a new profile created in the default location
(~/.thunderbird/xxxxxxxx.test). But I'm experiencing the same problems with a
new profile created in /mnt/daten/test. I do have write-access there of course.

Comment 27

[sairuh (rarely reading bugmail)]

I was able to add and verify the feeds from comment 23 using 2004113005-0.9
(linux fc2). although my profile is located under
~/.thunderbird/xxxxxxxx.profile-name...

Comment 28

[Marcia Knous [:marcia]]

Using the 12/3 Tbird branch, I am able to add all of the feeds below with no issues.

Comment 29

[Marcia Knous [:marcia]]

minusing for 1.0 - it appears that all of the RSS feeds that have been listed
here now work. We should probably keep this bug open to track issues as they arise.

Comment 30

[Jean-Michel Philippe]

I just uncountered the problem with SourceForge "inactive feeds" and Thunderbird
1.0. Try this one:

http://sourceforge.net/export/rss2_projnews.php?group_id=48103&rss_fulltext=1

which validates at http://rss.scripting.com/.

Comment 31

[Rafael Plana Maranzato]

I detected that if you subscribe a feed without a bar after the domain (i.e.
http://mysite.com) Thunderbirds tries to import the feeds and does not list the
content. I have tested it also with a specific site
(http://rafaelpm.rssblog.uol.com.br x http://rafaelpm.rssblog.uol.com.br/) and
localhost using IIS

Comment 32

[Bryn Keller]

http://www.xoltar.org/rss.xml still hangs once progress bar reaches 100% on
Thunderbird 1.0.

Comment 33

[Scott MacGregor]

the two feeds in question seem to be working now on the trunk. 

Comment 34

[Rafael Plana Maranzato]

(In reply to comment #33)
> the two feeds in question seem to be working now on the trunk. 

I downloaded Thunderbird 1.0 and http://rafaelpm.rssblog.uol.com.br is still not
working.
