SDuesterhaupt commented 2 months ago

If I toggle the background job type on my test system (Nextcloud 29, updated over years including beta and RC versions) using the CLI

sudo -u apache php /var/www/public_html/nextcloud.domain.tld/occ background:ajax

then this error occurs:

In AppConfig.php line 821:

  conflict between new type (mixed) and old type (string)

This error does not occur in a productive system (version 29, updated over years excluding beta and RC versions, no fresh install). I assume that a database entry may be out of date.

wagnbeu0 commented 1 month ago

Can confirm the same issue here on my NC29.0.1 instance:

root@vm1:~# sudo -u www-data php /var/www/occ background:webcron
In AppConfig.php line 821:
  conflict between new type (mixed) and old type (string)
background:webcron

root@vm1:~# sudo -u www-data php /var/www/occ background:ajax
In AppConfig.php line 821:
  conflict between new type (mixed) and old type (string)
background:ajax

root@vm1:~# sudo -u www-data php /var/www/occ background:cron
Set mode for background jobs to 'cron'
root@vm1:~#

joshtrichards commented 1 month ago

Thanks for reporting.

Looks possibly related to changes made in PR #41755 that typed the values.

Not a PR or area of code I'm at all familiar with, but some clues in case someone feels like taking a closer look.

Allesanddro commented 1 month ago

Same issue here

tobykurien commented 3 weeks ago

Same here too. Additional info: if I run ./occ background:webcron to change it, I get:

In AppConfig.php line 821:

  conflict between new type (mixed) and old type (string)  

background:webcron

HammyHavoc commented 2 weeks ago

Seeing this too.

jarrodjay commented 2 weeks ago

Same here.

HammyHavoc commented 2 weeks ago

Same here.

I updated to the latest version of Nextcloud yesterday and it seemed to solve my problem with cron not working and also not being able to switch cron types.

theyoungstone commented 2 weeks ago

Same here.

I updated to the latest version of Nextcloud yesterday and it seemed to solve my problem with cron not working and also not being able to switch cron types.

Nextcloud up to date (stable version : Nextcloud Hub 8 (29.0.2)) and not solved.

johnczer commented 1 week ago

Ditto on above

CNeutron commented 1 week ago

Same issue here: php occ background:ajax results in

In AppConfig.php line 821:

  conflict between new type (mixed) and old type (string)  

background:ajax

just updated from 28.0.5 --> 29.0.2

johnczer commented 1 week ago

And still happening on 29.0.3:(

joshtrichards commented 6 days ago

Rather than posting "me too" comments, upvote :+1: the initial report above, unless you have some new information to add.

It just spams everybody and wastes developer time needed to fix bugs. Thanks!

P.S. This is a known issue (reproduced). That's why I labeled it 1. to develop last week. :)

joshtrichards commented 6 days ago

As a workaround, for the time being to toggle the background mode, you should be able to change the value directly:

occ config:app:set --value cron --type string core backgroundjobs_mode

Where cron is one of { cron, webcron, ajax }.

It's also possible to force it to be mixed, but I'm hesitant to suggest changing that since I'm not sure what's actually going on here and I still have yet to wrap my head around #41755, the migration path, what the expected behavior was here (other than obviously not breaking the ability to set the background mode).

We are using the new IAppConfig api in cron.php. That means if cron.php was called once, and the backgroundjobs_mode was not already set to cron, it's then changed to cron AND type is set from 2 (mixed) to 4 (string).

When the value was typed once, it's not possible to set a new value without giving a type. Unfortunatly , the commands and provisioning_api are using the old IAppConfig api which uses type mixed.

Pull request for the commands: https://github.com/nextcloud/server/pull/46185

The provisioning_api also needs an update to use the types.

Needs some input from @ArtificialOwl.

The provisioning_api also needs an update to use the types.

The final version should support all types, but the patch below made it work again.
