Trying to get property of non-object

[aronovgj]

Reproduce:

• Open settings

What can I see:

• Solr starts using a lot of CPU
• Nextant settings look as if nextant is not configured at all (all fields empty, no indexes ran)
• After a few seconds the settings look correct
• Error:
  Trying to get property of non-object at /var/www/nextcloud/apps/nextant/lib/Controller/SettingsController.php#113

./occ nextant:check

How many segments in your index ? Is it slow also to get the result using the check command ?

[aronovgj]

All the output comes immediatelly after running the command, except for the segments. Those take some time.
also running the command repeatedly, the first result is
- 25 segments
the second is
- segments
The third is like the first again.

And the corresponding error:
Trying to get property of non-object at /var/www/nextcloud/apps/nextant/lib/Command/Check.php#90

i'll have a look, in the meanwhile you can

./occ nextant:optimize

[aronovgj]

That is interesting. After doing ./occ nextant:optimize the error is gone and ./occ nextant:check shows me 5 segments (what are those anyway? It showed 25 before). corresponding error is also gone.
Everything else is the same, meaning quite a long loading time in the admin panel, empty nextant settings while loading, high CPU usage.

When you do a ./occ nextant:check there is still a delay to display the number of segments ?

[aronovgj]

Yes, a 20 seconds delay.

[ArtificialOwl]

Can you have a look to the logs of your solr when you're executing ./occ nextant:check ?

In the meantime, remove this line so your Admin Interface is working

Also confirming that removing the line helps.

[ArtificialOwl]

I have currently no idea why it takes you so long, but would you try this patch and see if ./occ nextant:check is still slow ?

[aronovgj]

Works. No more delays.

[ArtificialOwl]

ok, 0.6.6 fix that
