703978 - All RSS feed properties lost

Status: RESOLVED FIXED

(MailNews Core :: Feed Reader, defect)

Description

[Boris 'pi' Piwinger]

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:7.0.1) Gecko/20110928 Firefox/7.0.1 SeaMonkey/2.4.1

I observed my feeds are not updated. I checked under "manage feeds". All except for two were not displayed.

I tried to import my last export which failed claiming it would not be a valid OPML file.

I manually tried to subscribe to the first address from the OPML file. SeaMonkey claimed I am already subscribed to the feed. Yet obviously I have no chance to modify or delete said subscription.

This happened once before and I set up a new RSS account which now failed again after three or so.

So this is total data loss.

I just tried to set up a new account and import the feeds. It worked. Yet when I tried to download and went back to the manage subscriptions page again two feeds were missing: https://www.xing.com/protect/stories and http://www.linkedin.com/rss/nus?key=$KEY ($KEY of course my special key).

When I try to subscribe to them again it said I am subscribed, yet it is not available.

So it is a complete failure.

Did you try to log the http protocol to see what was going on ?

I haven't. I am not sure where it is logged or how I could switch logging on. 

I have created yet another account which is working at the moment. But I am happy to follow up on the problem if you let me know how.

The strange thing is that the feeds are not even shown in the list.

Thanks

these feed issues all seem to fall into the following scenario:
1)feed stops updating (for reasons of bug 682606 or bug 687430 or something yet unknown).
2)user tries to fix by deleting a feed folder (which doesn't unsubscribe), or unsubscribes (which doesn't complete, bug 705504), or tries to import feeds which aren't visible but in fact are in the feeds.rdf database.

folder moves/deletes are not handled correctly regarding feeds.  the biggest problem is that the list of feeds in a folder in Subscribe dialog comes from the folder database (.msf) feedUrl property which may no longer have feeds which are in the feeds.rdf database (thus already subscribed).  this out of syncness is the core problem.

further, unsubscribing a feed does not remove items in feeditems.rdf, so a resubscribe will not get those messages (if they've been deleted).  bug 705504 fixes that.

As far as I can see, none of these are what I am observing. 

In my case the feed was not accessible at all. I subscribed and never unsubscribed. Yet I could not "manage" the feed.

you did not see the feed listed in the Subscribe dialog folder because the folder's .msf file feedUrl property (list of feeds for the folder in Subscribe) was incorrect.  due to folder pane feed item moves/deletes, or perhaps no action of your own.

you could not subscribe, since the feed *was* in the feeds.rdf database.  but you couldn't see it to remove it, due to the out of sync.

creating a new account creates new clean files.

Attachment: Broken feeds.rfd

Great, it happened again with my new account, less than one week old. It worked yesterday, now it is broken. Only one feed works. I haven't done anything except renaming one folder. Even the feeds in another (untouched) folder are invisible now.

One thing I can observe in feeds.rdf is that the renamed folder name is not reflected in <fz:destFolder RDF:resource="mailbox://...>.

Yet also the correct folders don't work anymore.

Attached the file with only one secret key replace, the rest is original. Nothing secret in there;-)

Renaming the one folder back to the name as in the feeds.rfd brings back the particular feed in that folder. Yet all feeds in the folder Interesting are still gone.
