Server Update, 2013-06-10

Another week, another release! This release is mostly bug fixes, but I’m sure a lot of people will be happy to notice that we have finally resolved MBS-357. That’s right – we no longer have a single clear text password in the MusicBrainz database. We’re sorry that it took so long, but at least it’s finally been done! Other than that, this release mostly builds on top of the new schema change features, and provides bug fixes for things that have regressed.

Schema change release, 2013-05-15

Today we released a schema change update for MusicBrainz. Schema change updates change the format of the underlying MusicBrainz database and allow us to store more information, or model information in a richer/more correct form.


This release specifically includes some exciting new features:


A new entity is this release is the “area” entity, which can track countries, subdivisions of countries, cities, and other such location entities (venues, however, will be another entity). While this release primarily only introduces the entity, migrating only our existing list of countries, it’s now also possible to add start and end locations to artists, and to mark works as anthems. Editing of areas, their aliases and annotations, and area-area and area-url relationships, is limited to a new class of “Location Editor”.

ISNI Codes

The International Standard Name Identifier (ISNI) is an ISO standard that identifies public identities of parties. We now have support for storing ISNI codes inside the MusicBrainz database, which will make it easier to cross-reference data in MusicBrainz with other databases.

Multiple Release Events

Releases can now have multiple date and country pairs, whereas previously they could only have one country and one date. This will allow us to more accurately store information about releases that occur in different areas at different dates, but are otherwise the same physical product.

Forthcoming Features

We also began work on the database support for some future MusicBrainz features:

Track MBIDs

All tracks on mediums now have unique identifiers. This will allow people to refer to a specific track in a release in a way that is more resilient to editing than just the track name or position. Currently we have database support for this, but track identifiers are not yet exposed in either the website or the web service.

Dynamic Work Attributes

Dynamic work attributes will let us introduce new attributes to describe works without schema changes

Free Text Relationship Attribute Credits

This feature will let editors specify an alternative name for relationship attributes to specifically exactly which model guitar was used in a recording, rather than the current vague “electric guitar” attribute. Support for this feature is now in the database (in the link_attribute_credit) table, but the UI to do this editing is still to be finished.

Support more formats in the Cover Art Archive

Uploading cover art to the cover art archive will soon support a few other image formats, starting with PNG.

Other Schema Changes

The remaining smaller schema changes are:

  • The wiki transclusion version mapping is now stored in the database, not a flat file.
  • The link_type.short_link_phrase was renamed to link_type.long_link_phrase.
  • The work.artist_credit column was dropped.
  • Collections can now have a description.


If you are currently running a slave database, then you will need to perform a few manual steps to upgrade to the new version:

  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-2013-05-15
  5. Run carton install --deployment to install any new perl modules.
  6. Run carton exec -Ilib -- ./ from the top of the source directory.
  7. Set DB_SCHEMA_SEQUENCE to 17 in lib/
  8. Turn cron jobs back on, if needed.
  9. Restart the MusicBrainz web server, if needed.

Please see the instructions in our more recent blog post instead of these instructions.

Server Update 2013-04-22 and a Notice Regarding Passwords

We’ve just finished deploying a new update to the MusicBrainz website, but before covering release notes we’d like to clarify a few points regarding the recent password leak.

There have been a few reports suggesting that MusicBrainz was attacked or compromised, but we can assure that this is not the case. As stated in our original blog post, we accidentally included private information in our otherwise routine public backups. As the majority of MusicBrainz data is available under the Creative Commons BY-NC-SA or CC0, these backups are intended to be public – the mistake was the human error in accidentally including password hashes.

A few of you also mentioned that we didn’t respond in a timely fashion in alerting users via emails. We completely agree with these comments, and apologise for not being able to respond quicker. Unfortunately, we did not have the infrastructure to do such mass mailing, and as we didn’t want to rush this out to the point of making yet more errors, it took us a little longer than we all would have liked.

With that out of the way, here’s what we’ve done in the last fortnight. Many thanks to Michael Wiencek, Nicolás Tamargo, and the rest of the MusicBrainz team for their work on this release.

Potential Security Leak

What Happened?

On March 29th 2013 we discovered that one of the MusicBrainz database dumps contained password hashes for a large portion of MusicBrainz accounts. While we don’t believe that these password hashes are either useful or widely distributed, we are requiring all users change their passwords.

What Data Was Leaked?

bcrypt password hashes, with a cost parameter of 8, for all accounts as of March 25th 2013.

Why Did This Happen?

We’ve recently began work on a long standing ticket against MusicBrainz server – MBS-357, “don’t store passwords in clear text”. We’re going to be moving away from clear text passwords, and we’ve decided to use one of the current industry standards for hashing passwords – bcrypt. Using bcrypt means that MusicBrainz will store only the hashes of passwords, which in laymans terms is a “fingerprint” of the password. Hashing means that we never store the actual password, but only the hash. There are many hashing functions available, and bcrypt is designed to be an expensive hash to compute with an adjustable “cost” – this makes it very hard to find out what the original password was via brute force attacks.

While this does mean that it’s hard to extract passwords from the hashes, the initial round of hashing passwords to move away from clear text is time consuming. As such, we built a small program that would gradually hash passwords over the course of a few days in order to make the switch from clear text passwords to secure password hashes done with as little downtime as possible.

This script hashed the password into the bcrypt_password column for all editors, and would also be notified when users changed their password in order to update the hash. Unfortunately, our database dump scripts sanitize this data by excluding data after-the-fact, rather than declaring what data to dump before running the script. As such, it dumped the entire editor table with the new column, as we forgot to add a rule to exclude this column.

Our Response

The database dumps that contain this data were promptly deleted, and have been replaced with correctly sanitized database dumps. Unfortunately logs from this server do show that this database dump was downloaded, and as we have no real indication of where this data now is, we’re treating this seriously. We have adjusted our database dumping scripts to be very specific about exactly which data they should export, so that in the future we will not leak private data by making the same mistake again.

We’re extremely sorry about this mistake, and while we don’t believe this data should allow attackers to retrieve user passwords, we can’t be 100% certain. As such, we require that all users change their password as soon as possible.
