Server update 2012-10-29

The MusicBrainz team are all mostly back after participating in Google Summer of Code and having a small face-to-face meetup, so we’ve finally got round to getting the latest release out. Because of so much travel, this is a tiny release, but here’s what’s changed:

Bug

  • [MBS-4727] – Regression : Can’t add ISWC when adding work
  • [MBS-5463] – Release editor fails on releases without disambiguation comment
  • [MBS-5478] – Can’t unselect all recordings / works

Improvement

  • [MBS-5422] – Show close time in open auto-editor elections

Virtual Machine for 2012-10-15 release now available

If you’ve been waiting for the VM for the 2012-10-15 version, your wait is over! I’ve updated the Server Setup page with the links to the latest VM. As usual it contains a replicated database that can easily catch up to the latest data.

Grab yours now and start replicating!

UPDATE: This virtual machine is broken — we’ll work to get a new one up soon.

Update on postgresql 8.4 issues and missing functions in upgrade

We’ve been seeing a number of issues with the upgrade scripts for this release reported here on the blog, in IRC, as well as the ticket tracker. We’ve got a couple bits of news for those upgrading from codebases older than mid-August and those using versions of PostgreSQL older than 9.0:

  1. MBS-5473: This is the ERROR: function controlled_for_whitespace(character varying) does not exist migration problem. Slaves with imports done before mid-August are missing a few stored procedures that are necessary for the upgrade. This has been fixed in the master branch as of commit 082e608c074641e2e8df2c0809d35421b02c7899 — to run the upgrade, run git fetch origin, then git checkout 082e608c074641e2e8df2c0809d35421b02c7899, then continue with step #6 of the original instructions. If you already started the upgrade but failed on the ‘merge-duplicate-credits’ script (as is likely, with this bug), don’t worry: at that point in the upgrade, restarting is not an issue.
  2. MBS-5475: This is the ERROR: syntax error at or near “ORDER” migration problem. Unfortunately, this one’s more serious: on PostgreSQL 8.4, our upgrade scripts don’t work, as one uses a feature introduced in 9.0 (as previously mentioned) After some hours of investigation, it appears that this issue can’t be resolved reasonably; therefore, for 8.4 users the upgrade path is a data re-import using a recent (post-schema-change) codebase and a data dump from October 17th or later. We’d also recommend updating to PostgreSQL 9.x at the same time if that is possible.

Sorry again for the inconvenience.

2012-10-15 migration on postgres 8.4 is broken

Our users have reported a bug where migrating a slave DB on postgres 8.4 results in this error:

ERROR: syntax error at or near “ORDER”
LINE 6: SELECT array_agg(artist_credit ORDER BY artist_credit AS…

If you are 8.4 please wait on your migration — we’re hoping to have a workaround ready today. If you need to get this fixed sooner, moving to postgres 9.x or importing the 2012-10-17 data dump would solve this problem.

Sorry for the troubles!

Updating MusicBrainz slave instances for 2012-10-15

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-2012-10-15-schema-change
  5. Run carton install --deployment to install any new perl modules.
  6. Run carton exec -- ./upgrade.sh from the top of the source directory.
  7. Set DB_SCHEMA_SEQUENCE to 16 in lib/DBDefs.pm
  8. Turn cron jobs back on, if needed.
  9. Restart the MusicBrainz web server, if needed.

This upgrade requires quite a bit of disk-space to execute; your slave may run into trouble if there is less than 10Gb of disk space free. If you’re on a disk space constrained machine, you may want to consider re-importing the data rather than upgrading in place. The next data dump should be available in about 14-16 hours from now.

Schema change release 2012-10-15

Server update, 2012-10-01

We’ve just finished pushing out an update today, which will be the last update before the schema change, which is now due in 2 weeks. Sadly, this release doesn’t feature the much anticipated relationship editor, which had to be reverted at the last minute as we still think it could do with more user testing. Hopefully it will make the next release!

This release features work from Aurélien Mino, Nicolás Tamargo, nikki, patate12, Pavan Chander, Ulrich Klauer and the MusicBrainz developers. Thanks for your work everyone!
