Deleted feed get's error in log

[Siggi0904]

Hi,
I deleted a feed in news app website.

Since then I get the following error from this deleted feed:

{"reqId":"NM8cpZn6bWKU9IYfE2JN","level":3,"time":"2021-10-16T18:15:35+00:00","remoteAddr":"","user":"--","app":"PHP","method":"","url":"--","message":{"Exception":"Error","Message":"copy(/git-logo.png): failed to open stream: No such file or directory at /var/www/clients/client39/web136/web/nc/apps/news/lib/Fetcher/FeedFetcher.php#346","Code":0,"Trace":[{"function":"onError","class":"OC\\Log\\ErrorHandler","type":"::"},{"file":"/var/www/clients/client39/web136/web/nc/apps/news/lib/Fetcher/FeedFetcher.php","line":346,"function":"copy"},{"file":"/var/www/clients/client39/web136/web/nc/apps/news/lib/Fetcher/FeedFetcher.php","line":393,"function":"getFavicon","class":"OCA\\News\\Fetcher\\FeedFetcher","type":"->"},{"file":"/var/www/clients/client39/web136/web/nc/apps/news/lib/Fetcher/FeedFetcher.php","line":125,"function":"buildFeed","class":"OCA\\News\\Fetcher\\FeedFetcher","type":"->"},{"file":"/var/www/clients/client39/web136/web/nc/apps/news/lib/Service/FeedServiceV2.php","line":265,"function":"fetch","class":"OCA\\News\\Fetcher\\FeedFetcher","type":"->"},{"file":"/var/www/clients/client39/web136/web/nc/apps/news/lib/Service/FeedServiceV2.php","line":342,"function":"fetch","class":"OCA\\News\\Service\\FeedServiceV2","type":"->"},{"file":"/var/www/clients/client39/web136/web/nc/apps/news/lib/Service/UpdaterService.php","line":55,"function":"fetchAll","class":"OCA\\News\\Service\\FeedServiceV2","type":"->"},{"file":"/var/www/clients/client39/web136/web/nc/apps/news/lib/Cron/UpdaterJob.php","line":71,"function":"update","class":"OCA\\News\\Service\\UpdaterService","type":"->","args":["*** sensitive parameters replaced ***"]},{"file":"/var/www/clients/client39/web136/web/nc/lib/private/BackgroundJob/Job.php","line":52,"function":"run","class":"OCA\\News\\Cron\\UpdaterJob","type":"->"},{"file":"/var/www/clients/client39/web136/web/nc/lib/private/BackgroundJob/TimedJob.php","line":59,"function":"execute","class":"OC\\BackgroundJob\\Job","type":"->"},{"file":"/var/www/clients/client39/web136/web/nc/cron.php","line":128,"function":"execute","class":"OC\\BackgroundJob\\TimedJob","type":"->"}],"File":"/var/www/clients/client39/web136/web/nc/lib/private/Log/ErrorHandler.php","Line":92,"CustomMessage":"--"},"userAgent":"--","version":"21.0.4.1","id":"616b16c842052"}

How I can delete this feed permanently?

[Grotax]

If the error still pooping up that would mean that you still have such a feed. I'm currently working on improving the logo function, can you share the feed? It seems to be git related so maybe gitlab or github?

[Siggi0904]

Hi,
I deleted the feed after that the error occurs. In my list of feeds there isn't it anymore.
I deleted the feed because it doesn't exist anymore at the website. It was from vdi.de.

How I can clean it up?
Where I can look for forgotten parts to clean up?

[Grotax]

Normally there shouldn't be any left over parts, either the feed exists or it does not exist.
You can use occ to list all feeds of one user:

occ news:feed:list $username

With the id of a given feed you can delete it:

occ news:feed:delete $username $feed-id

If that doesn't help and you still get these errors something must be broken in very strange way.
The next level would then be directly on the DB but let's only talk about that when above is failing.

I also assume you are the only user on that nextcloud so that nobody else might have a feed that causes this error.

[Siggi0904]

Okay, double checked. These was old entries.

Actually is:
{"reqId":"30p4OoTZ5fFlvT05RRgs","level":3,"time":"2021-10-17T13:30:14+00:00","remoteAddr":"","user":"--","app":"PHP","method":"","url":"--","message":{"Exception":"Error","Message":"copy(/git-logo.png): failed to open stream: No such file or directory at /var/www/clients/client39/web136/web/nc/apps/news/lib/Fetcher/FeedFetcher.php#346","Code":0,"Trace":[{"function":"onError","class":"OC\\Log\\ErrorHandler","type":"::"},{"file":"/var/www/clients/client39/web136/web/nc/apps/news/lib/Fetcher/FeedFetcher.php","line":346,"function":"copy"},{"file":"/var/www/clients/client39/web136/web/nc/apps/news/lib/Fetcher/FeedFetcher.php","line":393,"function":"getFavicon","class":"OCA\\News\\Fetcher\\FeedFetcher","type":"->"},{"file":"/var/www/clients/client39/web136/web/nc/apps/news/lib/Fetcher/FeedFetcher.php","line":125,"function":"buildFeed","class":"OCA\\News\\Fetcher\\FeedFetcher","type":"->"},{"file":"/var/www/clients/client39/web136/web/nc/apps/news/lib/Service/FeedServiceV2.php","line":265,"function":"fetch","class":"OCA\\News\\Fetcher\\FeedFetcher","type":"->"},{"file":"/var/www/clients/client39/web136/web/nc/apps/news/lib/Service/FeedServiceV2.php","line":342,"function":"fetch","class":"OCA\\News\\Service\\FeedServiceV2","type":"->"},{"file":"/var/www/clients/client39/web136/web/nc/apps/news/lib/Service/UpdaterService.php","line":55,"function":"fetchAll","class":"OCA\\News\\Service\\FeedServiceV2","type":"->"},{"file":"/var/www/clients/client39/web136/web/nc/apps/news/lib/Cron/UpdaterJob.php","line":71,"function":"update","class":"OCA\\News\\Service\\UpdaterService","type":"->","args":["*** sensitive parameters replaced ***"]},{"file":"/var/www/clients/client39/web136/web/nc/lib/private/BackgroundJob/Job.php","line":52,"function":"run","class":"OCA\\News\\Cron\\UpdaterJob","type":"->"},{"file":"/var/www/clients/client39/web136/web/nc/lib/private/BackgroundJob/TimedJob.php","line":59,"function":"execute","class":"OC\\BackgroundJob\\Job","type":"->"},{"file":"/var/www/clients/client39/web136/web/nc/cron.php","line":128,"function":"execute","class":"OC\\BackgroundJob\\TimedJob","type":"->"}],"File":"/var/www/clients/client39/web136/web/nc/lib/private/Log/ErrorHandler.php","Line":92,"CustomMessage":"--"},"userAgent":"--","version":"21.0.4.1"}

Then it looks like an general copy(/git-logo.png) error.
Can I do something to fix it temporarily?

[Grotax]

One of your feeds provides a feed image, this is a standard field in RSS and I think also in atom.

Our feed library feed-io calls it logo.

We extract the value of the logo and use phps built-in copy to download the file.

What I didn't think about at the time of implementation that people would use relative links, this causes copy to look for the file locally, which obviously doesn't exist.

I have been working on a new implementation.

Probably it's the easiest to wait for the next release, I will try to do that soon.

I'm still interested in that feed as an example, as we currently rely on actual real feeds for testing. If it's a public feed that you can share I would love to check it out with my new implementation.

It must be related to git as it the image has git in its name.

Okay, great thanks for the answer and fixing these issue.

Then I go forward to fix the GuzzleHTTP error.
GuzzleHttp\Exception\RequestException: cURL error 60: SSL certificate problem: certificate has expired
Actually I cannot get any app updates because of certificate issue.
My server admin and nextcloud devs didn't find a way to fix that.

Thanks.

[Grotax]

Is it possible that your admin runs an older version of openssl on the server? https://www.openssl.org/blog/blog/2021/09/13/LetsEncryptRootCertExpire/

[Siggi0904]

They said it is fixed and nextcloud devs created a pr.
But looks like certificates are still in user space behind the overall certificates.

[Siggi0904]

fixed with new version and can be closed.
