V3.0.1 beta scans not showing complete on dashboard but logs show complete

Matthew Bourns 7 months ago updated by Tom 5 months ago 6

When a scan is started it adds all the new items found and the user can view/ download etc but on the admin dashboard it does not show as complete the Total line is not populated. The log file though indicates that it is complete or at least it does from what I can tell. When I try to start another scan I get the message that one is already running. At the moment I simply stop and restart the server to resolve this. When I restart it then shows the total line populated from the previous scan 


Here are the last lines from my log file after I stopped and restarted the server:

Let me know if there is anything else you need or changes that I should make to my setup to get it working. 

Under review

This one's harder. Working on it...

Thanks let me know if you need anymore details or anything you would like me to try

Since 3.0.0, Ubooquity looks for duplicate files after scanning collections.

This can be a veeeeery long operation on big collections and cause issues like the one you encountered, so I deactivated it by default and added an option (in advanced settings) to re-enable it.

Here is the fixed version (3.0.2) : https://vaemendis.net/ubooquity/downloads/Ubooquity-3.0.2.zip

Let me know how it goes.

My scans show as complete now and I can launch another scan as well. On my library previously it never showed complete and after anywhere between 24-48 hrs after I started a scan the app would crash or my pc would lock up if I didn't stop the server and start again. Did you make any changes to the duplicate detection that you would like me to try out and see if there are any improvements apart from the new flag?

flag?

Thanks, for now I just made the feature optional.

I'll look into optimizations after the release of 3.1.0 (which will be the official Ubooquity 3, not in beta anymore).
