Schema change release, 2016-05-23 (with upgrade instructions)

Starting with this release, PostgreSQL 9.5 is now our minimum supported version. In order to import any future data sets, you will need to upgrade your installation to version 9.5.

Due to unforeseen problems with the Live Data Feed (AKA replication), users with slave databases will be required to first import a fresh data dump into their new 9.5 installation. We apologize that this is the case, but even had this stream not been broken, doing a clean import is faster and easier than doing the migration. For details on what happened during this rather lengthy schema change release, stay tuned for a post mortem blog post that covers the details.

If you have a non-replicated standalone database, you can use pg_upgrade and run ./upgrade.sh directly, but for simplicity we strongly recommend importing the latest data dump. Thus, we will only provide instructions for a clean import:

Make sure you have PostgreSQL 9.5 installed, and your database settings in lib/DBDefs.pm are updated to point to the 9.5 installation if you currently have an older version of postgres running. If you already have postgres 9.5 and want to replace the existing database there, you’ll need to drop it first (using dropdb or from within psql). Be careful that you’re not dropping any important data if this is a standalone database that you’ve made changes to.
Take down the web server running MusicBrainz, if you’re running a web server.
Turn off cron jobs if you are automatically updating the database via cron jobs.
Switch to the new code with git fetch origin followed by git checkout v-2016-05-23-schema-change-v2
Run cpanm --installdeps --notest . to ensure your perl-based dependencies are up to date. Note the dot at the end.
Set DB_SCHEMA_SEQUENCE to 23 in lib/DBDefs.pm
Download the latest data dumps. If you don’t need historical edit data, excluding the edit dump will speed up your import significantly.
Initialize a new database from the data dumps downloaded in step 7. Detailed instructions for doing this are located in INSTALL.md in the musicbrainz-server repository; if your data dumps are in /tmp, the command should simply be something like ./admin/InitDb.pl --createdb --import /tmp/mbdump*.tar.bz2.
After the import has finished, turn cron jobs back on, if applicable.
Restart the MusicBrainz web server, as well as memcached, if applicable.

We would like to thank bitmap, Gentlecat, zas, chirlu, reosarevok, gcilou for contributing directly to the release and we’d also like to thank all of the people who helped test, debug or otherwise offer support in this quite difficult release. Thank you!

And finally, here’s the list of changes you can expect in the upgrade:

Schema change release, 2015-05-18 (including upgrade instructions)

Our previously mentioned schema change release is finished! Below will be upgrade instructions, including configuration updates for replication access tokens.

This release does not include UI for several of the schema change patches, which will (hopefully) happen for next release on June 1. The incomplete patches are MBS-7489 (credits for artists in relationships), MBS-4145 (tag upvote/downvote), and MBS-8004 (collections for additional entity types). These patches have had their schema change components finished, but the UI was incomplete or needed more work.

Schema Change Upgrade Instructions

These are largely as previous upgrade instructions, using the tag v-2015-05-18-schema-change. The primary difference is the inclusion of configuring an access token for replication.

Make sure your REPLICATION_TYPE setting is RT_SLAVE and your DB_SCHEMA_SEQUENCE is set to 21 in lib/DBDefs.pm. If you’re running a standalone server, you can run the upgrade, but it may be easier to just import a new data dump!
Ensure you’ve replicated up to the most recent replication packet available with the old schema. (if you’re not sure, run ./admin/replication/LoadReplicationChanges and see what it tells you; if you’re ready to update, it should say “Mismatched schema sequence, 21 (database) vs 22 (replication packet)”).
Take down the web server running MusicBrainz, if you’re running a web server.
Turn off cron jobs if you are automatically updating the database via cron jobs.
Switch to the new code with git fetch origin followed by git checkout v-2015-05-18-schema-change
Run ./upgrade.sh (or carton exec -Ilib -- ./upgrade.sh if you’re using carton, with very old setups).
Run cpanm --installdeps --notest . to ensure your perl-based dependencies are up to date. This release adds a dependency on LWP::Protocol::https, for fetching replication packets from the new server; many systems may already have this installed, but it should be verified.
Set DB_SCHEMA_SEQUENCE to 22 in lib/DBDefs.pm as instructed by the output of ./upgrade.sh
Assuming you have been updating your server with replication, it will now be necessary to configure an access token:
1. Go to https://metabrainz.org/supporters/account-type and choose your account type as applicable. If you’re an individual, non-commercial user of the data, choose “non-commercial”; if not, choose an applicable tier in the “commercial” section. If you’re not sure of the appropriate tier, make your best guess; it can be adjusted if necessary.
2. Then, from https://metabrainz.org/profile, create an access token, which should be a 40-character random alphanumeric string provided by the site.
3. Finally, add this token to lib/DBDefs.pm under the REPLICATION_ACCESS_TOKEN configuration option. The final configuration section should look something like sub REPLICATION_ACCESS_TOKEN { "ck3UpgwgOXhWC6SpFcd99rZOTjzfrei3gQlgZZ9z" }.
4. Don’t reveal your access token! If you do, inadvertently, you can use the MetaBrainz site to generate a new token, invalidating the old one. (The one in the example above is one I created for myself and then invalidated — don’t get any ideas, it won’t work!)
Turn cron jobs back on, if applicable.
Restart the MusicBrainz web server, if applicable. It’s also recommended you restart memcached.

Finally, the list of bugs closed this release:

Bug

[MBS-4436] – Medium titles cannot be longer than 255 charaters

Improvement

[MBS-1347] – Implement aliases for release groups, releases and recordings
[MBS-7906] – maybe don’t show “”≠null diff. in edit pages
[MBS-8279] – Remove empty_artists etc. database functions

New Feature

[MBS-8302] – Add Live Data Feed access token support

Task

[MBS-8266] – Make medium titles VARCHAR NOT NULL
[MBS-8278] – Update DB_SCHEMA_SEQUENCE in DbDefs.pm.sample
[MBS-8283] – Remove DB constraint that disallows empty event names

Not included in this list but also relevant is MBS-8349, which while fixed for a previous release, in this release is also applied to old slave servers, which may help performance for some queries.

Schema change upgrade instructions, schema 21

This upgrade shouldn’t be substantially different than past upgrades, now that we’ve fixed a few bugs with the process. To upgrade:

Make sure your REPLICATION_TYPE setting is RT_SLAVE and your DB_SCHEMA_SEQUENCE is set to 20 in lib/DBDefs.pm.
Ensure you’ve replicated up to the most recent replication packet available with the old schema. (if you’re not sure, run ./admin/replication/LoadReplicationChanges and see what it tells you).
Take down the web server running MusicBrainz, if you’re running a web server.
Turn off cron jobs if you are automatically updating the database via cron jobs.
Switch to the new code with git fetch origin followed by git checkout schema-change-20-to-21
Run ./upgrade.sh (or carton exec -Ilib -- ./upgrade.sh if you’re using carton, with very old setups).
Set DB_SCHEMA_SEQUENCE to 21 in lib/DBDefs.pm
Turn cron jobs back on, if needed.
Restart the MusicBrainz web server, if applicable. It’s also recommended you restart memcached.

That’s it! The only real difference from the past is the specific tag to be used: schema-change-20-to-21, which is a couple of fix-up commits past the regular release tag.

NGS Bug fixes 2011-09-21 and the New "Split Artist" Feature

Apologies for being a few days late here, but we’ve just finished updating the servers with the latest set of bug fixes and new features. This release brings a new feature that people have been asking for since NGS – the ability to “split” an artist into artist credits.

Split Artist

With NGS, we had the ability to link multiple artists to recordings/releases/etc. While our migration script handled most cases, there are some cases when it was unclear how to automatically split artists, and we opted to leave that artist unchanged. While it was possible to manually edit references to this artist, it was painful. We now have a convenient way to make this process easier. In the sidebar of artists there is now a “split into separate artists” link:

The new "split into separate artists" feature

Clicking this link will present you with a form where you can choose the new set of artists. For example, here’s me splitting the single “Alix Perez & SpetraSoul” artist into the correct separate artists:

As with the other types of editing in MusicBrainz, this edit has to be voted on by other editors before it is applied.

The split artists edit type can only be used on artists that have no relationships, other than “collaboration” relationships. If the artist does have collaboration relationships, edits to remove all collaboration relationships will be entered at the same time. Note also that this will not remove the now empty artist entirely – that will happen when ModBot does its daily cleanup.

Bugs

We’ve continued working through the bugs as well, and here are the tickets that have been closed in this release.

Schema change release, 2011-07-11

Today we released our first schema change update since NGS. This change is quite a radical one, as it merges both of our databases (“READWRITE” and “RAWDATA”) into a single database. For most users of the database, this probably won’t affect you, but you’re encouraged to run the upgrade process anyway. Here’s what you need to do:

Take down the web server running MusicBrainz, if you’re running a web server.
Turn off cron jobs if you are automatically updating the database via cron jobs.
Set DB_SCHEMA_SEQUENCE to 13 in lib/DBDefs.pm
Make sure your REPLICATION_TYPE setting is RT_SLAVE
Switch to the new code with git fetch origin followed by git checkout v-20110711-schema-change
Run ./upgrade.sh from the top of the source directory.
Install the perl modules Algorithm::Merge and Algorithm::Diff
Turn cron jobs back on, if needed.
Restart the MusicBrainz web server, if needed.

This process may take a while, as it has to dump one database into another, and download a few extra changes to ensure slaves aren’t missing any data. The RAWDATA database should no longer be in use and you should be able to drop it, but waiting to see that everything is working well might be a good idea.

This schema change does not introduce any new data. For everyone else, here’s a list of what got fixed since the last release!

[MBS-1977] – ModBot is unable to close some edits
[MBS-1979] – Unable to edit a “later translated versions” relationship with change direction
