Picard 0.15 released!

The 0.15 stable version was finally released today, with some new features and bug fixes since beta2. There were too many small changes to list, but here’s a partial changelog with the most user-visible ones:

Version 0.15 – 2011-07-17:

  • Added options for using standardized track, release, and artist metadata.
  • Added preferred release format support.
  • Expanded preferred release country support to allow multiple countries.
  • Added support for tagging non-album tracks (standalone recordings).
  • Plugins can now be installed via drag and drop, or a file browser.
  • Added several new tags: %_originaldate%, %_recordingcomment%, and %_releasecomment%
  • Changes to request queuing: added separate high and low priority queues for each host.
  • Tagger scripts now run after metadata plugins finish (#5850)
  • The “compilation” tag can now be $unset or modified via tagger script.
  • Added a shortcut (Ctrl+I) for Edit->Details.
  • Miscellaneous bug fixes.

You can download the new version and report bugs for it 🙂

Schema change release, 2011-07-11

Today we released our first schema change update since NGS. This change is quite a radical one, as it merges both of our databases (“READWRITE” and “RAWDATA”) into a single database. For most users of the database, this probably won’t affect you, but you’re encouraged to run the upgrade process anyway. Here’s what you need to do:

  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. Set DB_SCHEMA_SEQUENCE to 13 in lib/DBDefs.pm
  4. Make sure your REPLICATION_TYPE setting is RT_SLAVE
  5. Switch to the new code with git fetch origin followed by git checkout v-20110711-schema-change
  6. Run ./upgrade.sh from the top of the source directory.
  7. Install the perl modules Algorithm::Merge and Algorithm::Diff
  8. Turn cron jobs back on, if needed.
  9. Restart the MusicBrainz web server, if needed.

This process may take a while, as it has to dump one database into another, and download a few extra changes to ensure slaves aren’t missing any data. The RAWDATA database should no longer be in use and you should be able to drop it, but waiting to see that everything is working well might be a good idea.

This schema change does not introduce any new data. For everyone else, here’s a list of what got fixed since the last release!

Bug

  • [MBS-1977] – ModBot is unable to close some edits
  • [MBS-1979] – Unable to edit a “later translated versions” relationship with change direction
  • [MBS-2026] – Subscribed artists open edits won’t load for editors with large amounts of subscriptions
  • [MBS-2442] – MB postgres unaccent extension overwrites unaccent.so library shipped with postgres-contrib
  • [MBS-2689] – Timeline isn’t working in Opera 10
  • [MBS-2698] – Some tables are not replicated through Live data feed
  • [MBS-2812] – Adding track times has caused a failed dependency for an edit which changed the track titles.
  • [MBS-2826] – Web service returns malformed XML (not escaped properly)
  • [MBS-2831] – “Edit medium” edit display: Artist credits changes are incorrect
  • [MBS-2974] – I don’t receive e-mail when someone votes no to my edit any more
  • [MBS-2981] – Changing the case of recording comments should be auto-edits
  • [MBS-2986] – tracklist_index was not populated during NGS
  • [MBS-2995] – Caught exception in MusicBrainz::Server::Controller::WS::2::ReleaseGroup->release_group_browse “Can’t call method “format”

Improvement

  • [MBS-1500] – Remove tracklist_index.tracks
  • [MBS-1707] – Advanced tracklist in RE: “Title” to “Disc title”
  • [MBS-2242] – Disable editing of Medium title when there’s only one medium
  • [MBS-2434] – Combine READWRITE and RAWDATA
  • [MBS-2462] – Other edit types that don’t highlight what has changed between old and new values
  • [MBS-2583] – “Edit Medium” should show you which medium is being edited with respect to the overall release
  • [MBS-2767] – Release-group XML result should include first release date

Beta release of libmusicbrainz4 with NGS support

Andy Hawkins and Lukáš Lalinský have been doing some work on libmusicbrainz, and a beta release of version 4 is now available. Here’s what Andy has to say:

Hi all,

In conjunction with Lukas I’ve been working on a complete rewrite of libmusicbrainz to support the new Web Service v2 released alongside NGS. I’m happy to announce the first Beta release of this new library (libmusicbrainz4).

The library is written as a relatively simple parser for the results from the Web Service, with as little logic as possible. This should mean it is easy to maintain to keep in step with any changes in the schema for the XML Web Service.

The main interface is a C++ class ‘CQuery’, that returns a Metadata object containing a parsed version of the response. There is also a C interface that loosely wraps the C++ classes.

Using the library requires a good understanding of the queries and responses to and from the Web Service.

The library is available to download here:

ftp://ftp.musicbrainz.org/pub/musicbrainz/libmusicbrainz-4.0.0beta1.tar.gz

Documentation is generated from the source (make docs), an online copy is available here:

http://users.musicbrainz.org/~luks/docs/libmusicbrainz4/

If you find any issues, please report them using JIRA (under the project ‘libmusicbrainz’) here:

http://tickets.musicbrainz.org/

I will attempt to be available via this mailing list and the #musicbrainz-devel IRC channel on freenode in order to answer questions if at all possible.
