New system:cron is generating output when everything is fine

[Faldrian]

Steps to reproduce

1. Update Owncloud to 10.3
2. Wait until server executes cron via crontab

Expected behaviour

I should only receive e-mail / notification when a cron could not run or some error happened. If everything was fine, no output should be generated by the cronjob, so nothing is reported by my server.

Actual behaviour

From 10.3 on there is a progress bar that is updated 14 times, generating output.
This progress bar is no error / warning information and should not be output when running as cron job.

Server configuration

Operating system: CentOS 6

Web server: Apache

Database: MySQL

PHP version: 7.2.23

ownCloud version: 10.3

Updated from an older ownCloud or fresh install: Updated from 10.2.something

Where did you install ownCloud from: originally downloaded tar file and extracted.

In my case, after installing of v10.3 the cron.php doesn´t run when I schedule a start over system cron. If I copy the cron.php from v10.2.1 it runs as before.

We are moving away from cron.php - please use occ system:cron ...

We shall change this .. agreed

I don´t understand in the right way, because I use the system cron to start the cron.php each 10 minutes with the follow line:

root /bin/su -s /bin/sh -c "/usr/local/bin/php72 -f /volume1/web/owncloud/cron.php" http

Its on a Synology. I don´t understand, what is changed and what I have to modify.

So I think, I have to use

root /bin/su -s /bin/sh -c "/usr/local/bin/php72 -f /volume1/web/owncloud/occ system:cron" http

instead of the old command?

The system:cron is also generating a newline https://github.com/owncloud/core/blob/v10.3.0/core/Command/System/Cron.php#L137, this has to be removed as well (for cron execution at least).

@Kaelber
yes, that is what I did and it works

see #36304 - feel free to test ...

Thanks a lot, it runs ....

@DeepDiver1975 Thanks! Will test this evening. :)

I have the same issue as mentioned by Faldrian (with 16 progress bar lines), but also a notice beforehand saying:

The process control (PCNTL) extensions are required in case you want to interrupt long running commands - see http://php.net/manual/en/book.pcntl.php

I can’t install that extension because I am running owncloud on a shared host. The cron job is working fine, though. Maybe that notice could be turned off as well?
I tried to add --no-warnings with no success. (I am not experienced with command line stuff, so maybe that’s the reason it didn’t work …?)
