System.IO.FileNotFoundException exits library scan

[antivist 1]

Hi all,

 

so here's my problem:

Im running Emby Server 4.1.1.0-1 on DSM 6.2.2-24922.

 

In german we have characters like: ä, ü, ö, ß and so on. After a library scan / metadata update Emby renames these characters to for example: ¿½ for ü. 

A while ago (before 4.x update), I've been browsing my Library Folder and was renaming these paths back to ¿½ -> ü for a better reading.

A few days ago I was wondering why my movie library was not displaying recently added movies, while other libraries like series do.

So I've been investigating the issue. 

 

- Was manually triggering some library scans.

- Deleted library.db in data folder.

- Reinstalled Emby Server and restored previous backup.

With no success. Movie library remained unchanged.

 

So I took a look into logs and I've found the following:

2019-05-22 20:53:50.366 Error LibraryMonitor: Error in Directory watcher for: /volume1/video/Filme

2019-05-22 20:53:50.366 Info LibraryMonitor: Stopping directory watching for path /volume1/video/Filme

So what happens is that somewhere this path was saved (I assume library.db) and after renaming the folder to: Weltengänger (2018), this file could no longer be found, of course.

 

Unfortunately this stops the entire library scan, which then results in no new titles for this library.

 

But what I would have expected is that if there is a System.IO.FileNotFoundException raised, this path would have been either ignored or removed from library.db or where it is saved and the scan just skips this particular path instead of exiting the entire process.

 

After renaming the paths back to where Emby is expecting to find files in, library scan is running without problems and movies been added again.

 

Hope this helps someone with similiar problems and maybe leads to some improvements.

Hi Luke,

 

the old logs were overwritten or deleted so I recreated the issue, please see the log attached.

 

It happens at / around 2019-06-02 23:42:10.556.

 

I'd guess this is an issue with encoding.

 

Greetings,

 

Sebastian

@@Luke,

 

the exception is still fired but it seems that the scan is continuing.

Unfortunately it creates a new folder with the original filename when the exception is raised.

 

This is what I did:

 

I renamed the original folder "Das Komplott - Verrat auf höchster Ebene (2017)" to "Das Komplott - Verrat auf höchster Ebene (2017)"  notice the Ã¶ is now ö.


In my library folder theres now only "Das Komplott - Verrat auf höchster Ebene (2017)".

Now I did a scan from the webinterface.

The exception is fired and the folder  "Das Komplott - Verrat auf höchster Ebene (2017)" was created by emby with only a .nfo file as content.

 

I do now have two folders: Das Komplott - Verrat auf höchster Ebene (2017) and Das Komplott - Verrat auf höchster Ebene (2017).

I'll attach a log so you can have a look. Scroll to timestamp: 2019-07-28 18:00:19.294
