Server update, 2012-06-12

We’ve just finished pushing out a new set of changes to the MusicBrainz Servers. This release is mostly a bug fix, and importantly fixes a critical bug that could cause recordings to be deleted. Many thanks to Nicolás Tamargo, Ian McEwen, Wieland Hoffmann, hrglgrmpf and the MusicBrainz team for their work on this release.

Server update, 2012-05-28

We’ve just finished pushing an update to our web servers. This is our first release since the schema change, and we’ve tried to address the problem of artist landing pages. As a temporary solution, we’ve split the page up by type a bit more now, which we hope is a step in the right direction. We’re currently discussing this at User:Reosarevok/Overview Options on the wiki, and your feedback is important. If you feel strongly about this, please have a read at the ideas on that page and feel free to comment/add your own.

This release features work from Ian McEwen, nikki, Joachim LeBlanc, Nicolás Tamargo and the rest of the MusicBrainz team. Thanks everyone for your hard work!

Post schema change fix for importing clean data

Yesterday we found a bug that prevents the import of a post schema change update data set. We’ve pushed out a fix for this and tagged it with: 

v-2012-05-15-import-fix

If you’re planning on importing a new data set, make sure to check out this tag, rather than the tag mentioned in this entry.

Schema change server update, 2012-05-15

Nearly one year after we released NGS, we have another schema change update with lots of new features!

This release contains 9 new features and improvements that take advantage of the new schema. These are:

  • More social user profiles which can now have Gravatars, languages (and the users proficiency) age and country.
  • More expressive aliases for artists, labels and works. Aliases can now have types, sort names and multiple aliases may be used per a locale, along with the ability to mark one alias as ‘primary’ for that locale.
  • Release group types have been separated into primary and secondary types. A release group now has 1 primary type and may have multiple secondary types. This allows us to have ‘remix compilation albums’, for example
  • Works may have multiple ISWCs
  • Artists, labels and relationships may be marked as ‘ended’ to indicate that they have ended, but the exact date is not known
  • Vinyl style/free text track numbers are now supported.
  • Works may have a lyrics language associated with them
  • Artists and labels may have multiple IPIs
  • We have moved to use ISO 639-3 for our language table. While not all languages are exposed at the moment, this gives us a lot more flexibility going forward.

Many thanks to nikki for going way beyond our expectations for testing (and patience!); to Ian McEwen for his continued work on statistics; and to the MusicBrainz team for making this all happen.

If you have a replicated instance of MusicBrainz, please follow these instructions to get your server running on the new schema:

  1. Take down the web server running MusicBrainz, if you’re running a web server.
  2. Turn off cron jobs if you are automatically updating the database via cron jobs.
  3. Make sure your REPLICATION_TYPE setting is RT_SLAVE
  4. Switch to the new code with git fetch origin followed by git checkout v-2012-05-15-schema-change
  5. Run carton install --deployment. If you have not switched your installation to using carton, please read INSTALL.md on how to do this.
  6. Run carton exec -- ./upgrade.sh from the top of the source directory.
  7. Set DB_SCHEMA_SEQUENCE to 15 in lib/DBDefs.pm
  8. Turn cron jobs back on, if needed.
  9. Restart the MusicBrainz web server, if needed.

If you are running a mbslave mirror, check out the latest code and read the upgrade instructions in the README file.

Official schema change release announcement for May 2012 release

We’ve been working on hammering out the details of the upcoming schema change release and we’ve settled on 11 tickets that we’re going to implement. For a detailed description of how our database will change, please refer to the our documentation for these tickets.

This release will happen on or about 15 May, 2012.

Schema change update

As per my previous blog post, today is the deadline for submitting tickets for consideration in the May 15 2012 schema change release. Eleven tickets have been championed for this release — you can see each of these tickets in the schema change release fix version in jira.

I would like to call your attention to three tickets that I think ought to get more input from the community:

  1. Split release group attributes into two types
  2. Lyrics language for works
  3. Add ISO 639-3 language codes to the database

If any of these issues interest you, please take a look and leave a comment if you have any input. Finally, I will be keeping track of the progress of the schema change release on this wiki page.

I’m hoping to put together a complete schema change document that outlines the exact changes to our schema on April 2.

Many thanks to all of the volunteers who adopted tickets and are moving them forward!
