Yesterday we held our mini-summit in London to great success. The MusicBrainz team huddled up in a hotel last night and finished writing up notes of everything we covered, and you can now have a look at them on the wiki at MusicBrainz Summit/2012-Mini_Summit/Notes. In general, we provided an update of what’s been happening at MusicBrainz, what’s coming up in the future, and heard how each company are using MusicBrainz. Discussions have started with respect to classical support, but don’t expect anything concrete any time soon!
Many thanks to everyone who came along to this summit and helped make it work – it was great seeing you all!
Sadly, our testing for replication failed to catch a problem with the instructions we posted yesterday. If, when running the replication scripts you encountered the below error, please read on!
Attribute (conn) does not pass the type constraint because: Validation
failed for 'DBIx::Connector' with value DBI::db=HASH(0x9e957d0)
(not isa DBIx::Connector)
We made some changes to our database connection routines recently, and the replication scripts were not correctly migrated. We’ve got these changes in now though, so to fix this problem, repeat the instructions in our previous post, but use the v-2012-01-12-schema-change-2 tag. This should correspond to commit eb89c2b51f79..., which you can verify by running git rev-parse HEAD.
We’ve just finished pushing out the scheduled schema change update today. A slightly rocky experience, but we’ve managed to get everything ironed out now and our servers are back to their normal selves. Before, I get into release notes, a few notes for people who’d like to upgrade their non-replicated servers. For replicated servers, please see this post.
First, update your repository to the v-2012-01-12-schema-change tag.
Next, disable any MusicBrainz cron jobs you might have scheduled to run
Run ./upgrade.sh provided in the root directory of your musicbrainz-server checkout.
Update your DBDefs DB_SCHEMA_SEQUENCE configuration option to 14.
Turn any cron jobs back on
And onto the release notes!
Bug

With Christmas, New Year, and all that fuss out of the way, I’ve finally been able to get a new release out. We’re only 2 weeks behind on this one I think… oops. Hopefully, we make up for it with these fixes. Also, just a quick reminder that our little scheduling website is open, and needs your feedback to help us decide what will make it into future versions. Happy editing!

Another update has just gone out, a few days later than planned. This is mostly a bug fix and minor improvement release. Sadly, when deploying the update we broke the release editor for anyone who was editing during the server switches – something we didn’t anticipate. Sorry! Here’s what’s changed:
Bug
[MBS-2371] – Can’t type in the basic tracklist editor
[MBS-2785] – Release Editor messes up release artist multi-artist credits
[MBS-3152] – Tracklist duplication with sub-second track duration differences

[MBS-3813] – Release editor gets stuck on tracklist tab saying there are errors when there are none
In an effort to bring the community into our development process more, I (ocharles) have built a new little application to help the MusicBrainz community decide exactly what we should focus on. I present to you, the Scheduling Game!
The Scheduling Game
The idea behind this little application is to let the community quickly scan through open issues and decide when they believe they should be fixed. Each editor is presented with 3 options:
Within 3 months. This ticket must absolutely be fixed within 3 months from now.
Within 12 months. This ticket should be fixed within a year from now. This means the ticket should be fixed within the year, but is not critical for the next 3 months
Unscheduled. This issue is not pressing and can be fixed much later.
Later, when issues have been voted on by enough people, the developers will try and decide how to schedule work to best fit the needs of the community.
A few disclaimers… Firstly, this is just an experiment! We don’t know how well it will work, though initial testing has shown it to already be quite useful. Secondly, it’s not really much of a game, but I wanted to give it a cute name (I know how picky everyone can be!). Currently only a subset of open tickets are available for voting on – specifically tickets in the “NGS + 1” and “Post NGS” milestones on JIRA, as these milestones are in need of a sorting.
The scheduling game is currently live on my server at http://scheduling.ocharles.org.uk/. You can have a look at the current (anonymous) votes at http://scheduling.ocharles.org.uk/results. If you have any questions or comments, you can reach me in IRC as ocharles or email oliver@musicbrainz.org. Happy voting!
A few days behind on this one, but we’ve got this release out. This release has one controversial change, which I want to discuss in this blog post.
Displaying Relationships on Release Pages
A lot of people want this, and we’ve shipped something that adds this functionality. However, a lot of people think this is too verbose, and to a point I agree – there’s a lot of information there that can be displayed better. However, work on this issue has been on and off for almost the past 2 years. We’ve got a solution here that while far from ideal will get this ball rolling.
This is an unpopular move on my half, but I’m asking users to please try and bear with us until the next release (scheduled in for 5th December), which is just over a week away. Hopefully having this fairly messy display so open will raise enough discussion on how exactly to move forward. If you really must see it gone, you can use AdBlock or user styles in your browser to hide the dl.ars element.
Changes in this Release
[MBS-2067] – CDStub not displayed in the "Matching CDs" section on CDTOC lookup page
[MBS-3668] – all edits including "Auto-edits" are being tallied as "Accepted" edits in editor profile
It’s been a while, but we’ve finally got a new server release out! This one didn’t go perfectly smoothly, and we had (more, i’m afraid) troubles with the release editor. We’ve got a fix for this out, so editing should be at least as stable as it was before. As always, please do continue to report any bugs you find. Here’s what’s changed:
Bug
[MBS-761] – Release has ASIN but no cover art ("No cover image available.")
[MBS-1169] – Musicbrainz website is missing HTML escaping on user entered data
[MBS-2529] – Orphaned release group and recordings after rejecting or cancelling a release/medium
With the summit arrangements this release has become delayed, but we’re happy to announce that we have just finished releasing this version (live from the summit!). Here’s what’s been fixed in this release:
[MBS-3070] – Release editor cannot be seeded with >99 for array-like elements
