It would be useful if (all) opds <entry> and <feed> elements contained the parent id or a href to the parent. This would be useful for 3rd party apps when scanning for updates as we could just read through the recently updated pages instead of traversing through every directory.

For example , if updating directories under Marvel, not having to scan through entire Darkhorse, DC, IDW folders that precede it alphabetically.

Hello

Is it possible to see isbn on books information ?

Thanks

Any idea why when i set it to original mode it crops off the top of every page of every comic i've tried?

I just installed Ubooquity and get the follwing when starting headless.

I started it using the .sh script in the download section. I altered it a bit (added -headless in the command line) because for some reason the server went down if that was not in?!

If I start the jar file in the GUI, the scanner works but the Themes do not work. And since this is my media server i want it to run headless and be accessible from the browser only.

Converting these is not acceptable as I have over 500, and all of what I download is PDF format.

What can I do to avoid this crash? I am using the latest JAVA on Windows 2012R2, this was working fine up until one of the latest updates of Ubooquity?

Here is the error message, as soon as I start an 'admin' scan of my magazines.

Would love to be able to add a magazine repository ..

Just a suggestion ..

Are there any plans to create a Synology Package? I see that it's possible to get Ubooquity running on a Synology but I just don't feel comfortable installing it manually.

I really love what you are doing with Ubooquity, I've longed for a Plex like solution to reading comics for a very long time and very much look forward to being able to use your product for both eBooks and Comics!

Hi,

I'd like to integrate ubooquity logs with the built-in synology logs. This way I'd benefit from notifications (important to know that I have an error requiring restarting ubooquity) and a better log management (search and archiving)

I tried to understand how logs are working in ubooquity, but couldn't figure out how to do that

The simplest solution I could think of is to configure ubooquity for syslog protocol: is it somehting you can do? can I define an IP/port for ubooquity to send the logs? that woudl definitely be a nice improvement, and I'm pretty sure there are light open-source libraries for that

Every now and then, during scanning, generally when my NAS is otherwise busy, I get a "java heap space" exception. The error is displayed in the log like the one at the bottom of this post.

Once the error has happened, ubooquity hangs: it's not killed (it still shows in the process list), but it's not responsive either. That's an issue in my view to hae a runnung process that really is dead

When that happens all I have to do, is stop and then restart ubooquity and the scan can generally continue without problem (it was a temporary issue; I also suspect memory leaks in the code since this only happens when scanning a large number of comics; it only ever happened when the number of comics to scan was above a few 1000s)

To avoid this situation,I propose to add some improvement to the scanning process:

• catch error when scanning a book; and dump a more relevant message to the user (for example, giving the name and the file and the item that was being scanned at the time of the error (cover image, title, metadata...)
• when a memory error occurs, shut down ubooquity process; In my case, since I've added a "nohup" commands in the startup script, upstart will restart ubooquity and I would have a functioning server instead of a zombie process (I've also added to the "nohup" commands a limit to the number of restart so that if ubooquity crashes 3 times in a row, then upstart will not restart it anymore)
• Optional: add the incriminated file to a "black list" so ubooquity doesn't try to rescan it next time... and of course allow the admin to reset the black list
