@setar Do you have any chance to debug this a bit? Where is the null coming from?

This should help to log the stack trace.

@setar no need to fork the project. :) Github makes this very easy to simply do it online:
- Go to the file at https://github.com/nextcloud/server/blob/master/lib/private/Files/Node/Node.php
- Click on the pencil icon in the top right to start editing
- Make your changes and put in a commit message
- Click the button below that to open a pull request :)
And that鈥檚 all :tada:

Hi,
I have also those errors with 13.0.6.
I can do the fix like @jancborchardt mentioned, but I haven't the knowledge in PHP. So I think it would be better if someone do the fix, who know want he do.

Okay - we should not fix the symptoms but actually the cause. In the proposed way the cause is simply hidden. 馃檲

Just a guess here, but I've seen numerous of errors when using the Full Text Search app. Not saying that it's the cause for this, but if everyone could confirm or deny if they use it or not maybe we have something to dig into.
I use it.

I also use it.
ggeorgg
on 23 Oct 2018
@setar @Tanarri @amicheals @feutl Do you use Full Text Search?
enoch85
on 23 Oct 2018
There are two apps about .. the "Full text search" and the "Full text search - Files" .. both are activated on my Cloud. I don't know if the " "#290" is indicating the Line number into the script .. when yes .. then it would be this function, which could be responsible for ..
protected function normalizePath($path) {
if ($path === '' or $path === '/') {
return '/';
}
//no windows style slashes
$path = str_replace('\', '/', $path);
//add leading slash
if ($path[0] !== '/') {
$path = '/' . $path;
}
//remove duplicate slashes
while (strpos($path, '//') !== false) {
$path = str_replace('//', '/', $path);
}
//remove trailing slash
$path = rtrim($path, '/');
return $path;
}
We already know that it is this function where the error comes up. The question is, where does it come from.
Therefore I modified the file with this function. (Have a look here)
You can see the stack trace. When I remember correctly, I wanted to upload a huge amount of data with the nextcloud client on my windows 10.
This is for example why we have this line here: "file": "/var/www/nextcloud/3rdparty/sabre/dav/lib/DAV/Server.php" in the stack trace.
A bit later we see: "file": "/var/www/nextcloud/lib/private/legacy/hook.php",
and then the fulltextsearch app comes in: "file": "/var/www/nextcloud/apps/files_fulltextsearch/lib/Events/FilesEvents.php",
So I think @enoch85 is right. It has to do something with the fulltextsearch. @daita Could you have a look? :)
ggeorgg
on 23 Oct 2018
seems to be from above fulltextsearch: the path from the broadcasted event is null.
But I wrote a fix for files_fulltextsearch (NC14) to ignore events when the path is null.
Should be fine, but I'll do more test tomorrow:
- https://github.com/nextcloud/files_fulltextsearch/commit/d930f9920c6ba2c645ca87ecfbb8c5acd3e75d30
- https://github.com/nextcloud/files_fulltextsearch/commit/6b1667c060ff8685f2628617c935626405c7df7b
_Note: still would be interesting to understand why the path is null_
daita
on 23 Oct 2018
Please upgrade your files_fulltextsearch to 1.1.0 (NC14)
daita
on 24 Oct 2018
i did the upgrade for: (i'm on NC 13.0.7)
Full text search 1.0.3
Full text search - Files 1.0.3
The Log still will be flooded ..

Thx for the hint upgrading the app .. currently i'm running nc 13.0.7 .. and Version 1.1.0 is not compatible with version 1.3, i think ( Required Nextcloud versions | >=14.0.0,<15.0.0 )

As the version of the software you've reported this for has reached end of life, I will close this ticket. If this is still happening after an upgrade to the latest version, feel free to reopen
