Search server jar/war files

We’ve been asked to provide instructions for how to upgrade a search server installation. We’ve got two answers for you:

  1. Short answer: Use the jar/war files linked below. Deploy these into whatever setup you’re currently using.
  2. Long answer: Check out the source (svn rev 13728) of the search server and follow the install instructions to build your own jar/war files.

Search server update for 2013-10-14 release

In conjunction with our main server release we’ve released a new search server. Thanks for your hard work on this release, Paul!

This release contains changes to match the Autumn 2013 database schema changes plus some bug fixes and improvements mostly to do with artist credits and aliases. See the detailed list of issues that are fixed in this version:

Bug

  • [SEARCH-46] – Searching for a release by releasename and artists english name will give no matches
  • [SEARCH-122] – Recording Search only adds release artist credit if different to recording artist credit and VA release
  • [SEARCH-304] – Webservice Json output for aliases when searching is inconsistent for boolean values
  • [SEARCH-311] – Recording, release and releasegroup search results incomplete artist aliases
  • [SEARCH-324] – Release search should return catalog numbers in ascending order

Improvement

  • [SEARCH-132] – Allow to filter release search by quality
  • [SEARCH-242] – The searcher can’t guess that the artist name one’s looking for is alias or artist name ☞ look for both
  • [SEARCH-288] – Include alias sortnames when searching works

2013-10-14 schema change release update instructions

As promised, here are the instructions for updating any instances of MusicBrainz you might have. You will need to perform these 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-2013-10-14
  5. Run carton exec -Ilib — ./upgrade.sh (or simply ./upgrade.sh if you aren’t using carton, such as for VM users or fairly new installs).
  6. Set DB_SCHEMA_SEQUENCE to 19 in lib/DBDefs.pm
  7. Turn cron jobs back on, if needed.
  8. Restart the MusicBrainz web server, if needed.

If your server fails to start or cron is having issues, it may be a missing perl module problem. To check for any missing perl modules, follow the instructions in INSTALL.md.

October 14 schema change complete

We’ve just finished rolling out the fall schema change release. Apart from the /place/create endpoint failing, the site is back up in full read-write mode now.

Read on for the changes in this release — our next blog post will give instructions on how to upgrade your instances of MusicBrainz.

Thanks to everyone who worked on this release!

Schema change release tomorrow at 1700UTC

Tomorrow, Monday 14 October, 2013, 17:00 UTC (10:00 PDT, 13:00 EDT, 18:00 BST, 19:00 CEST) we’re going to release our next round of schema changes!

As it is typical with our fall schema changes, this one is a little simpler and more focused on cleanup, rather than massive new changes. This gives me hope that we will have smoother release than we did in the spring. 🙂

We’re going to make the site read-only and run off our backup database server while we upgrade our primary database server. I suspect that we should be in read-only mode for about an hour. The exact start time is not quite known — we’ll start our release process at 17:00 UTC, but when we go to read-only is hard to tell. We’ll tweet and give a shout in IRC when we’re ready.

Server Update 2013-09-30

With the MusicBrainz summit happening just this weekend, and most work continuing on the upcoming schema change release – this server update is a tad on the light side! However, we do at least have something to show. Thanks to nikki for the main change in this release:

Bug

  • [MBS-6735] – ProcessReplicationChanges breaks with update packages that cross the limit boundary

New Feature

  • [MBS-5789] – Make links for HTTPS enabled sites use schema independent links

The Git tag for this release is v-2013-09-30.

Server Update 2013-09-16

Hello all. We’ve just pushed out another small little update to MusicBrainz. This release is small while we continue to focus on getting the upcoming schema change ready, so there are a handful of bug fixes and improvements. Thanks to Frederik “Freso” S. Olesen, Michael Wiencek and the rest of the MusicBrainz team for their work on this release. Here’s what’s changed:

Changes for upcoming schema change release: 2013-10-14

For our fall schema change release we’re going to fix the issues listed in this Schema change, 2013-10-14 fix version. This schema change, much like our previous fall schema changes, is going to be a little lighter than our spring changes. The two big changes that you should be aware of are:

  • MBS-6046: Remove PUID support. PUIDs have been deprecated for quite some time in favor of using AcoustID. This change completes our switchover to AcoustID.
  • MBS-6068: Remove _name tables. With NGS we introduced tables that isolated all of the name strings for a given table, in order to reduce duplicate strings in our database. Sadly, this proved to be more pain that gain, so we’re going to remove them. This will make writing queries for our schema much easier. Sadly, this means that if you use the MusicBrainz database directly, (as opposed to using our Web Service, which we recommend) then you will likely need to update your SQL queries.

The rest of the changes will have a much smaller impact: Adding a disambiguation column for areas, adding places, and adding the ability to mark a relationship as deprecated. We’re also making some minor changes to our non-replicated tables that will not be visible to our Live Data Feed users, but are more convenient to make during a schema change.

The scheduled date for this release is Monday, 14th October, 2013.

We’re going to take the HTTPS plunge!

Yesterday in our dev meeting we agreed to take the HTTPS plunge for all of our web site traffic in as little as 2 weeks time. This means that all web site traffic (not the web service) will be served over HTTPS; if you visit any MusicBrainz HTTP URL (e.g. http://musicbrainz.org ) you will be redirected to the equivalent HTTPS URL (e.g. https://musicbrainz.org ). This will not be applied to our web services, you’ll still be able to access those with HTTP. However, we do encourage all of our web service users to make use of HTTPS when possible.

We have one bug to address before we make this switch. And if we can find a sufficient fix for this in time, we’re going to make the HTTPS switch on 16 September 2013. If we can’t find an acceptable fix, we’ll have to postpone this switchover.

If for some reason you can see that switching all web site traffic to HTTPS is a bad idea, please leave us a comment ASAP.

Server Update 2013-09-02

We have a tiny release to kick off September, as we’ve been focusing quite heavily on tightening up the reliability and ease-of-maintenance of the servers themselves. However, we still have a few important bug fixes to release. Here’s what’s changed:

Bug

  • [MBS-4730] – Sort names for artist search hint aliases are displayed, but cannot be edited.
  • [MBS-6218] – When a Person with a gender is merged into a Group, ModBot ISEs.
  • [MBS-6561] – End column empty in search results for ended artists with no end date
  • [MBS-6635] – Several reports not updated since May 15
  • [MBS-6690] – JSON web service ISE with inc=aliases
  • [MBS-6698] – Wiki excerpts truncated by mid-sentence initials (eg, of names) that are mistaken for periods ending a sentence.
