Since I upgraded to NC17.0.3 I get many errors like this in the log.
What does it mean? Can I do something?
NC17.0.3, Ubuntu 18.0.4, nginx

Hallo,

change the WhatsNewController.php in nextcloud / core / controller / as this follows.

CHANGE OF:
$resultData = [
‘changelogURL’ => $whatsNew[‘changelogURL’],
‘product’ => $this->defaults->getName(),
‘version’ => $currentVersion,
];

CHANGE IN:
$resultData = [
‘product’ => $this->defaults->getName(),
‘version’ => $currentVersion,
];
if (isset($whatsNew[‘changelogURL’])) {
$resultData[‘changelogURL’] = $whatsNew[‘changelogURL’];
}

Best regards.
Enis.

Big thanks in advance!

Ok. first bug fixed. The next error is
/apps/workflowengine/lib/Helper/LogContext.php#55

Go now to https://github.com/nextcloud/server/commit/41fd0aaa264cde537aff20f951bf75eaf23d36c0

Good luck

Before that, the php file tried to evaluate a ‘zero’, of course this is not possible. Zero is not defined. If (isset ()) checks whether changelogURL is not ‘zero’ and if this is true it writes the result to the log.

Is this a bug that should be reported at Github?

11

I got a new error messages after applying this change:

Use of undefined constant ‘changelogURL’ - assumed ‘‘changelogURL’’ (this will throw an Error in a future version of PHP) at /var/www/html/core/Controller/WhatsNewController.php#94

Use of undefined constant ‘version’ - assumed ‘‘version’’ (this will throw an Error in a future version of PHP) at /var/www/html/core/Controller/WhatsNewController.php#92

Use of undefined constant ‘product’ - assumed ‘‘product’’ (this will throw an Error in a future version of PHP) at /var/www/html/core/Controller/WhatsNewController.php#91

Update: I change ’ to " and didn’t get the error message when restarted the docker container. Maybe the solution? (My knowledge of PHP is like 1 on a scale 1-100)

That was probably due to the formatting of the text in the code box from @enis45 . For anyone else having the issue benis had, here the copy&paste friendly version:

CHANGE OF:

$resultData = [
'changelogURL' => $whatsNew['changelogURL'],
'product' => $this->defaults->getName(),
'version' => $currentVersion,
];

CHANGE IN:

$resultData = [
'product' => $this->defaults->getName(),
'version' => $currentVersion,
];
if (isset($whatsNew['changelogURL'])) {
$resultData['changelogURL'] = $whatsNew['changelogURL'];
}

EDIT: It seems that people already made the developers aware of this on Github (https://github.com/nextcloud/server/issues/19490) and that it will be fixed with the next update. For the time being the above code fixes it temporary.

Still complaining about ’ instead of ". With " it seems to work tho.

15

In that case it seems to be a problem with the editor you are using. I tried it with Atom, Notepad++ and the internal editor of WinSCP and it works.

You can however also swap ' with " if that’s working better for you.

16

Interesting, I am using nano.

17

Indeed, since nano and vim is working for me as well. Ah well, if double quotes is working for you and/or others, you can use double quotes as well.

18

I was just worried that it would “mean” something else with " instead of ’ (my PHP knowledge is extremely low).

19

No worries :+1:t3: The difference between single and double quotes is actually pretty slim. One just needs to be careful of the case when to use them.
