I wonder whether there is a way to make amarok connect to the mysql server via a unix domain socket?

Not a good idea. For one, people don’t want their music collections cluttered up with random file crap (iTunes does it and it’s annoying as hell). Second, XML is extremely slow to read and parse. Third, then you have to come up with a system to ensure those files are up to date, which is far more difficult than doing it in a central location.

I’m wondering, why not an .amarok/ folder in each folder of the collection, and inside that have an XML file with metadata for all of the music files in that folder?

I’m thinking that the use case for storing on a remote server is that you want to store the metadata along with the music anyway..

If the user moves files around –>
Store metadata based on a per-file UID so that it still applies when found in another folder. Move metadata to the correct place when discovered.

If double metadata is found for a file –>
Store a per-file timestamp with the metadata and use whatever was most recently modified.

Or is there a specific feature of MySQL databases that makes them better than XML files (indexing?)

You’re welcome.

As for your question, amarokcollectionscanner has never had anything to do with the database…

AWESOME. I was just lamenting the lack of remote MySQL in 2.1.

THANKS!

I’ve been waiting for this for a long time; thx! One question; will the cli amarokcollectionscanner honor these settings as well?

Just wanted to say thank you for this and the UTF-8 support. These aren’t as sexy as e.g. moveable panels but they are absolutely great improvements and I really appreciate that someone is working on making the internals solid rather than polishing the exterior.

There is an upgrade capability. I don’t know how it works. And this question has absolutely nothing to do with this blog post.

This isn’t the forum for bug reports. But it’s fixed in SVN.

Since I updated to said revision, Amarok does not compile any more for me:

[ 66%] Built target amarok_collection-mysqlecollection_automoc
Linking CXX shared module ../../../lib/libamarok_collection-mysqlecollection.so
/usr/lib/mysql/libmysqld.a(client.o): In function `mysql_close_free_options’:

/usr/lib/mysql/libmysqld.a(client.o): In function `mysql_get_ssl_cipher’:
(.text+0x12a6): undefined reference to `yaSSL_get_cipher_name’
…

It seems some of the linker flags with the regards to mysql are not properly set – at least that is what http://forum.ubuntu-fr.org/viewtopic.php?id=289837 says about this error.

Is it able to take the old (amarok 1.4) database back and keep its data?
Thanks

That is good news. The next step would be to have a central setting for using Databases in KDE. More and more apps (Akonadi, Digikam, Nepomuk, KGet …) are making use of SQlite/Mysql and some of them even ship the database with them.
