IMPORTANT: Proposed changes to the data returned by our web service

Our current web service at the /ws/2 endpoint returns too much data in a lot of cases and in many cases we suspect that the programs making the calls to the service don’t actually consume all of that data. We’d like to reduce the amount of unused data our web service returns, in order to reduce our bandwidth costs. We propose that:

  • The web service will no longer includes aliases and tags in relation elements. Regardless of what entity you may request, if the results of your request includes a relation element, any alias or tag elements that are currently returned will no longer be returned.
  • The web service no longer includes aliases and tags in for the Various Artists artist anywhere, unless you specifically request the Various Artist from the /ws/2/artist endpoint.

We’ve mocked up these changes in the following XML files:

We think that this will have a minimal impact on our web service users. If you use our web service, please tell us what you think about this. If you know someone who is using our web service, but may not read this blog, please forward a link to this post to them.

For more background on our research into this topic, please take a look at this document.

Server Update, 2012-01-28

We’ve just finished releasing the last release for January, 2013. This release is a combination of bug fixes and improvements to existing features, and was worked on by Frederik “Freso” S. Olesen, Michael Wiencek, Nicolás Tamargo, Pavan Chander and the rest of the MusicBrainz team. Thanks for your hard work, everyone! Here’s what’s changed:

All Our Git Repositories Are Moving To GitHub

On February 11th 2013, we will be shutting down the MusicBrainz hosted Git repository, in favour of using GitHub for hosting. While we will continue to take backups, these will be internal and thus git.musicbrainz.org will cease to operate as it currently does.

There are a few reasons for this move, but the predominent reason is so MusicBrainz can host less. We currently host a lot of our own software and this is straining the already-limited resources we have. If someone else can do something just as well or better than we can – then let them! Using GitHub also means we get a slightly better repository browser, which can make communicating and discussing code easier. However, we are not moving to pull requests, though we may in the future.

We already mirror git.musicbrainz.org onto GitHub, so if you are only interested in read access, we recommend changing your local clone now, to save confusion in the future. To do this:

  1. cd to your musicbrainz-server clone.
  2. Run git remote set-url origin git://github.com/metabrainz/musicbrainz-server.git

That’s it! You should now be able to git pull just as you did before.

GitHub has a few other possible protocols for cloning, so if HTTP or HTTPS is better for you, then check out the GitHub repository for all the possible links.

If you’re a developer currently developing against our repositories, then you should either fork the repository on GitHub, or contact us to talk about getting your keys added.

Sorry for the disruption!

Server update, 2013-01-14

After delaying this release by a week due to Christmas/New Year getting in the way, we have pushed out a new update of the MusicBrainz web site. This release consists mostly of bug fixes and a few outstanding tasks that we still needed to complete. Thanks to Frederik “Freso” S. Olesen, Michael Wiencek, Johannes Weißl and the MusicBrainz team for their work on this release! Here’s what’s changed:

Bug

  • [MBS-5288] – Use API when checking for WikiDoc changes
  • [MBS-5577] – Relationship Editor displays "vocal vocals"
  • [MBS-5663] – Leap year in "Edit Relationships"
  • [MBS-5716] – Reorder mediums edit is missing a space between medium title and old position
  • [MBS-5717] – Reorder mediums edit for mediums without titles shouldn’t include colons

Improvement

  • [MBS-5723] – Allow sorting collections by all columns, not just a select few.

Task

  • [MBS-3856] – Revert MBS-1052 "Amazon should lookup cover art by barcode too"
  • [MBS-5729] – Consolidate Metabrainz:Sponsors and About/Sponsors

Sub-task

  • [MBS-3974] – Filter by release country

The Git tag for this release is v-2013-01-14.

Replication issues, and packet 64833 is large

  1. We’ve ushered in the new year by discovering, then solving some issues with replication; packet number 64831 (from yesterday, 1AM UTC) didn’t build correctly and needed a bit of manual prodding. However, it’s now been pushed out and replication should be back to normal.
  2. As part of our fix process, we turned off production of replication packets for the bulk of today. As a result, packet number 64833 covers what would otherwise have been about 20 packets, and thus is somewhat large. The import process for this packet will accordingly take somewhat longer than usual.

Sorry for any inconvenience, and happy new year!

Server update, 2012-12-24

We don’t rest for seasonal holidays at MusicBrainz, and we’ve just finished pushing out another release! This one is quite a small one release – thanks to Frederik “Freso” S. Olesen, Nicolás Tamargo, Pavan Chander and the MusicBrainz team for their work on this release. Here’s what’s changed:

Yet another fixed VM uploaded

Though the last version of the 2012-10-15 VM fixed the .ovf to remove an accidentally-included extra disk, this time an incorrect version of a different disk was added. This has been corrected and the finished product tested a bit, so hopefully this time we won’t need another followup blog post!

This time it’s MusicBrainz 2012-10-15.ova, in the usual places.

Server update, 2012-11-27

We’ve just finished pushing out a tiny little update to the MusicBrainz servers. This one improves on the ‘set release group cover art’ feature, but exposing an interface to make these changes. Later work will expose this cover art in more places. So, here’s the grand list of what has changed! Thanks to the MusicBrainz developers for their work on this release.

Bug

  • [MBS-4627] – Highlight all images with pending edits

Improvement

  • [MBS-5265] – Add release-group front cover art support

The Git tag for this release is v-2012-11-27.
