Serviio

Hi,
these days I had some time to develop an add-on for Serviio in order to use native file monitoring features to trigger library updates. This should then allows any HDD with resources monitored by a Serviio instance to correctly go on sleep when in idle .

The add-on requires at least a Java 7 runtime, and it should works on any O.S. By far, it has been tested it on:

• Windows 7 - 64bit
• Embedded Linux - Kernel 2.6.31.8 - ARMv5 (NAS Zyxel NSA310)

ONLY LOCAL DIRECTORIES ARE FULLY SUPPORTED (network shares are partially supported with some limitations as described here: https://docs.google.com/spreadsheets/d/1QbTpL6onqhJU54N6IQtHG1bmK0XTBYLHbPmmjPufUlM/edit?usp=sharing)

Actually, the add-on is just a jar to add to the Serviio's classpath, and it works using an alternative main Java entry class which, in turn, starts Serviio and, immediately after, starts its own monitoring feature for libraries configured inside Serviio.
Once started, it will trigger a Serviio full libraries scan after 5 seconds since the last filesystem change detected on any of the monitored directory (the 5 seconds delay is needed to avoid to request multiple consecutive scans when multiple files/directories are added/changed/removed). It can also detect long-copying operations, waiting the copy completion before trigger the library update.

The add-on is also capable to detect Serviio library configuration changes, in order to update directories being monitored. However, the configuration change monitoring is quite hackish, so it could not work on Serviio versions other then 1.4.1.2.

If ZIP give me the permission, I will be glad to attach needed files (released under Apache License 2.0) and installation instructions, creating also a github repository for patches and contributions.

========= INSTALL INSTRUCTIONS =========

• Disable Serviio automatic library update
• Stop Serviio server
• Download the jar add-on from https://www.dropbox.com/s/zewom1tnuql1q ... -1.0.0.jar
• Put the add-on jar into "<SERVIIO_PATH>\lib" directory
• Edit "<SERVIIO_PATH>\bin\serviio.bat" (Windows) or "<SERVIIO_PATH>/bin/serviio.sh" (Linux) and change every occurrence of org.serviio.MediaServer to com.lukakama.serviio.watchservice.WatchServiceMainWrapper
• ONLY ON LINUX - Edit any Lunix daemon script and change every occurrence of org.serviio.MediaServer to com.lukakama.serviio.watchservice.WatchServiceMainWrapper if any
• Start Serviio server

Ok with me, if it's a separate Jar file and doesn't modify any original files.

Also, does this work with remote drives? I haven't implemented it like that because people who tested it confirmed the java 7 file monitor doesn't work with remote drives.

Great! The add-on just uses Serviio's classes, it doesn't overwrite or modify any file.

I will add the jar and instructions as soon as possible .



I made some tests and it seems to depend on JVM / Guest OS / Host OS combinations.
Here is a status summary (I will try to perform other tests using my NAS as guest): https://docs.google.com/spreadsheets/d/ ... sp=sharing

Well, it seems that native monitoring on network shares has some limitations. From my tests, it seems that using a Windows 7 guest, it is possible to monitor only up to 62 directories of a share on a Windows 7 host and only 40 on a Unix host (Samba shares). Also, Unix samba shares can be monitored only using Java 8.

So, I must say that the add-on should be used only on Serviio installations with local libraries, as like it should be for embedded NAS.

I want to do similar function for Linux based Serviio server. I started another topic about Linux implementation, but I want to advice form You. For triggering update action I use such command:



Work nice, but of course I have to write whole script.
So my question is, how to execute library update? I try something like this, without positive results:



Can You help me to create proper syntax for library refreshing?

I'm sorry, but I don't know how to help you : my add-on is directly connected to Serviio run-time code, so it uses undocumented APIs to force a library update.

However, the add-on should works well also with Linux based Serviio servers (I'm using it on my NAS - Embedded Linux - Kernel 2.6.31.8) .

You have to do a POST (not GET) request, with a XML/Json body describing the action. See example in the API website.

OK. So I used such syntax:



and the result is:



Bus as far as I know it is not right result. Sorry for my question but I am very new in REST implementation. Can You correct my syntax?

According to API documentation I finally use such syntax:



But the result is wrong:



What I am doing wrong?

I could be wrong, but the action name should not be enclosed in curly brackets:

YOU ARE THE MASTER!!! Just removing brackets is necessary! THX

While it does work because serviio will just return xml, your accept header doesn't make sense, you cannot accept both xml and json. However, as you aren't looking to parse the server's response, you don't care what you get.

A slightly more concice version:

Yep. It is more simple. Just "Keep it ASAP" (ASAP -> As Simple As Possible). THX!

Be so kind to explain what parameter I have to include in forceOnlineResourceRefresh call? What is id number of online source? Is it number of source in Serviio console "Online Library" table?

Finally I have a script for automatic database update for Linux. It starts from cron after system starts.
It works on native filesystem, mounted via loop, SMB or NFS and any mix. If any remarks - Welcome!
