Just for info: I (temporarily) reverted back to News 15.1.1

derritter88 on 2 Feb 2021

I updated to News version 15.2.2 via app store but error still occurs.

derritter88 on 3 Feb 2021

I can't reproduce this. How did you update?

SMillerDev on 3 Feb 2021

@SMillerDev
Yesterday I tried to update via app store and run into the same issues as mentiond in #1107
Then tried to update it manually via downloading it from Github (v 15.2.0).
Error occured 1st time.

Reverted back.

Today I downloaded 15.2.2 from app store without any issues.
After the update I received the same error message.

@SMillerDev @derritter88

I know what's going on, it's a deployment issue. In v4.8.0, FeedIo.php at line 235 is as following: https://github.com/alexdebril/feed-io/blob/master/src/FeedIo/FeedIo.php#L235

Here's the full method

    public function getBaseFixers() : array
    {
        return array(
            new Reader\Fixer\HttpLastModified(),
            new Reader\Fixer\PublicId(),
        );
    }

in the previous version it was like this https://github.com/alexdebril/feed-io/blob/v4.7.16/src/FeedIo/FeedIo.php#L235:

    public function getBaseFixers() : array
    {
        return array(
            new Reader\Fixer\LastModified(),
            new Reader\Fixer\LastModifiedSince(),
            new Reader\Fixer\HttpLastModified(),
            new Reader\Fixer\PublicId(),
        );
    }

And in v4.8.0, the LastModified fixer was removed because no longer required (and clearly not called by feed-io's users).

So the explanation must be that during the composer install or whatsoever, some of the files were updated / removed but src/FeedIo/FeedIo.php stayed in its previous state. Why ? Probably because of a permission issue, I suspect that the initial installation was done with a high-privileged user (for instance, root) and the updates were made with another one (www-data ? user with UID 1000 ?), so some of the files can't be updated. It's a highroad to random bugs, I highly recommend to wipe the vendor/ folder and re-install it cleanly (I'm not aware of the exact deployment process, but at the end vendor/ must contain the dependencies as they are described in composer.lock)

alexdebril on 3 Feb 2021

I've thought the same, but the https://github.com/nextcloud/news/releases/download/15.2.2/news.tar.gz only contains the following and this is what allegedly was installed ..?

        return array(
            new Reader\Fixer\HttpLastModified(),
            new Reader\Fixer\PublicId(),
        );

How could this happen if the app folder was replaced entirely as reported?

anoymouserver on 3 Feb 2021

Maybe just as a sidenote my detailed steps for the manual process:
I disabled the News app via php occ
Replaced the folder and "chowned" to www-data
Enabled the app again

For the automatic process all steps were done by the www-data user.

Smells like cache then. what happens after you restart Apache ?

Haven't tried that yet - give me a second and I'll restart Apache & PHP7.4-FPM

That solved the issue!!!
Many thanks.

Should that be documented somewhere?

derritter88 on 3 Feb 2021

Should that be documented somewhere?

That's really "how do I maintain a PHP server", I don't think that's up to news (or nextcloud) to document
