Schema change release downtime

On Tuesday 15 May 2012 at 18:00 UTC MusicBrainz will be unavailable for about 15-30 minutes while we release the latest and greatest schema on our main servers.

Sorry for inconvenience that this may cause you.

Next schema change release: May 15

We’ve talked a bit about our upcoming schema change release, but we hadn’t nailed down the exact date of the release. Now that we’re tangibly close, we’ve settled on the May 15th as the actual release date.

As a reminder, here are the tickets that will change our schema and here are all the tickets scheduled for the 15th.

Looking for Language Liaisons

As some of you may know, this summer through Google Summer of Code I’m working on internationalization of musicbrainz-server. As outlined in my proposal, I’m currently looking to find what I call “language liaisons”: folks willing to be the go-to person about a given language for me and other developers.

What’s expected of liaisons:

Willing to be pestered occasionally, by me or other developers, about language-specific concerns: when adding new features, and thus adding new strings, we’d like to be able to ensure nothing’s added that will need to be changed before it can be translated into a given language.
Willing to file bugs for strings already in the database that are untranslatable, should you find them.
Be on the musicbrainz-i18n mailing list; this will be the main venue for organization and communication about i18n issues.
Ideally, to be an active translator for your language – but this isn’t a requirement, because I’d like to get the widest global coverage I can; even if a language doesn’t currently have a translation, we don’t want to unintentionally sabotage future translators with untranslatable strings!

I’ll also be determining a (related) list of “target languages” for the summer, with the intention of releasing translation on musicbrainz.org with these languages at the end of the summer. I’ll consider for inclusion on this list languages that are both in active translation on Transifex and have language liaisons.

If you’re interested in being a language liaison, please contact me: ianmcorvidae (at) musicbrainz (dot) org, editor ianmcorvidae, or ianmcorvidae on IRC, and join the mailing list.

If you’re interested in i18n generally, please join the musicbrainz-i18n list. For more information on my project and musicbrainz-server i18n, see the server internationalization wiki page, my post on my personal blog, and my official proposal, or come ask about it on IRC or the mailing list!

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.

Search server release: 2012-03-23

Earlier today we switched the latest release of our search server live. Paul says:

In this new release of the search server the basic search will now search more fields and return variations of what you searched such as spelling mistakes and the scoring has also been improved. Advanced search now lets you search for when a field doesn’t exist and you can do exact searches that take accent characters into account using the new accent fields.

We’ve also upgraded to the latest version of Lucene, added a way to see how scores are calculated for results and added integration tests. Hopefully this will all help with future stability.

UPDATE: This code lives in svn and can be found at r13480. I’ve also created this tag.

Thanks for your hard work on this release, Paul. And also thanks to Ollie for taking time to push the server portions of this live today. Here are our release notes:

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:

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!
