Server update 2011-11-21

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.

Server update 2011-11-14

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.

Picard 0.16 released with AcoustID support

Lukáš Lalinský announced here:


We released a new version of Picard today. This new release includes a number of bug fixes. Unicode punctuation is now replaced by default for new users. Title standardization has been removed, as track titles now follow the same style guidelines as recording titles.

One larger change that is hidden by default is support for AcoustID fingerprinting. AcoustID is a new, completely open source, audio fingerprinting project, started by me last year. I’m really glad to finally integrate it with Picard. Integration with the MusicBranz website is planned for later. Configuring Picard to use AcoustID instead of AmpliFIND should be completely transparent, there are no visual differences in the scanning process. Note that this feature requires downloading an extra application, see the AcoustID wiki page for details.

Changes since version 0.15.1:

  • Added AcoustID support.
  • Fixed track metadata plugins.
  • Added new internal %_totalalbumtracks% tag field. (PICARD-16)
  • Track metadata plugins now run also on non-album tracks. (PICARD-7)
  • Fixed custom Various Artists name on the %albumartist% field. (PICARD-5)
  • Album artist is now correctly “translated”. (PICARD-1)
  • Unicode punctuation is now converted to ASCII by default.
  • WavPack correction files are moved together with the main files. (PICARD-15)
  • Unicode filename normalization on OS X.
  • Original release date is now saved into %originaldate%.
  • Allow tagging with localized artist aliases (PICARD-17)
  • Added a quit confirmation dialog. (PICARD-46)
  • Standalone recordings can be tagged with relationships now. (PICARD-10)
  • Refreshing an album will refresh its “other versions” listing. (PICARD-8)
  • “Unicode punctuation to ASCII” now works on album-level metadata. (PICARD-50)
  • DJ-mix tags should only be written to the medium where they apply. (PICARD-20)
  • Support URL redirects in web service/network request module (PICARD-54)
  • Jamendo and cover art is displayed on web page, but not loaded by Picard plugin (PICARD-52)
  • Edits to metadata in “Details…” menu not reflected in UI (PICARD-13)
  • The status bar/new metadata box is updated when a selected file/track is changed. (PICARD-14)

    for details on how to use this new search. However, indexes are currently only updated once a day, so the old search
    feature is still available for when you need to find something that may have changed in the last day.
  • XMLWebservice – This new XML based web service drastically improves on the old RDF based web service by being more standards compliant and

Server Updates

Voting “inline”, a faster voting infrastructure, send e-mails using your real e-mail address, and a small number of other changes.

Changes mainly of interest to MusicBrainz Users

Inline Moderation

(This feature by Robert Kaye)

In an effort to reduce the voting backlog, the system now shows you
one vote at a time whenever you’re on an artist, album or track page.
The moderation chosen is, in order of preference: for this artist; for one of
your subscribed artists; for an artist related to this artist; or anything
at random.  When you click one of the three voting buttons (yes, no,
abs) then the voting panel reloads to show something else to vote on.
The rest of the page remains unchanged.

Faster Voting Pages

The moderation database tables have been reorganised behind the
scenes.  The result of this is that
the voting pages (in particular)
should be much faster.  See “Moderation Table Restructuring” below
for more technical details of what’s actually changed.

Reveal My E-Mail Address

When sending an e-mail to another moderator, it’s now possible
(as long as you’ve told MusicBrainz your e-mail address) to choose
to reveal your e-mail address to the other party.  Doing so makes it
much easier for them to reply to you.  The default setting is
controlled by a new preference, which in turn
defaults to “off” (i.e. don’t reveal my address).
Read the help for more information.

Other Changes

  • When searching for moderations, you can now search for mods
    on artists related to some given artist.
  • Tied votes are now passed (previously there had to be a clear majority to
  • When sending an e-mail to another moderator, sometimes extra quotes were
    added to the subject line (so instead of the subject being Hi
    for example, it would be “Hi there”).  These
    stray quotes have now been removed.
  • The HTML generated by a “Link with Icon” (for an artist, album or track
    link) now ensures that the icon will be on the same line as the text which
  • For “Edit Artist Alias”, “Edit Artist Sortname”, “Edit Track Number” and
    “Merge Artist” moderations, if the record being changed is missing then close
    the moderation with a “Failed prerequisite” status instead of “Internal
  • The “Show TRM” page now sorts the matched tracks by artist and album, and
    only shows each album once (even if more than one track on that album
    matches the TRM).

New and Changed Documentation

Changes mainly of interest to MusicBrainz Programmers

If you download and import the MusicBrainz database (including the
moderation tables) from time to time, read “Moderation Table Restructuring”

Changes mainly of interest to MusicBrainz Server Programmers


(This feature by Duncan Findlay)

The MusicBrainz server now uses Mason
1.25 (previously we used 1.05).  Mason underwent something of a
redesign following 1.05, so making it past this “hurdle” should help us in
the future.

Moderation Table Restructuring

The moderation-related tables have been reorganised, so as to speed up the
voting pages.  Almost all queries against the moderation tables deal
with open moderations, but Postgres seemed to be having trouble optimising
those queries (despite an index on moderation.status).  Well, maybe we
missed something obvious, maybe not.  Anyway, what we’ve done is to
split the three tables (moderation, moderationnote and votes) into six
(moderation_open, moderation_note_open, vote_open;
moderation_closed, moderation_note_closed, vote_closed).  So most
queries can now just refer to moderation_open, which is a MUCH smaller table
than moderation used to be.

As a side-effect, the data for closed moderations is now dumped into a
separate file (mbdump-closedmoderation.tar.bz2), making the
mbdump-moderation.tar.bz2 file much smaller.  Hence, if you
want to download open moderation data but have no need for closed
moderations, life has just become a little easier for you.

Other Changes

The CreateTables-mysql.sql
script has been removed.  It was generally poorly maintained, and
hardly ever tested, and the costs of maintaining it outweighed the
benefits.  If you want to create a MusicBrainz database in MySQL,
start with the CreateTables.sql
has been fixed. RDF dumps now contain all artists
we have in the database.

Server Updates

Moderation Search; Add Album gets “Guess” buttons; a new “moderation suggestions” report.

Changes mainly of interest to MusicBrainz Users

Moderation Search

Previously it was only possible to list moderations using one of a number of
fixed means: for example, “New Mods”, “FreeDB Mods”, “Artist Mods”
etc.  Now, all of these have been replaced a rather flexible
Moderation Search facility.

Moderation Search allows you to find moderations according to any
combination of the following criteria: moderation status, automod flag,
moderation type, moderator, vote cast (by you or anyone else),
artist (including “my subscribed artists”), and moderation ID (range).
You can also query by album, or by track.
Finally you can choose whether to show them oldest to newest, or the other
way round.  The number of possible combinations is
simply astronomical.

The old, fixed search types (“New”, “FreeDB” etc) now simply pre-fill the
search form with the appropriate values.  So for example, you can run
one of the preset searches (say, “My Failed Mods”), and then click “Advanced
Search” to customise your current search in whatever way you please.
There’s a new page which lists
the presets.  If you like you can set a new
to cause the “Moderate” link in the top navigation bar to
go to that page instead of running the “New Mods” query.

Some other points of note:

  • Many more queries than before are possible.  For example, show me
    moderations by (some moderator name) which I haven’t voted on yet; or, show
    me (some moderator name)’s automods only.
  • Many of the moderation URLs have now moved.  Hopefully all the links on
    the site have been updated, but if you do hit an old link (e.g. in an old
    “subscriptions” e-mail) you should get redirected.
  • The “subscriptions” e-mails now contain an extra link, which is
    effectively like “New Mods”, but for your subscribed artists only.
  • There’s now a page where you
    can search for moderators
    (so you can include them in your
    search).  Interestingly this is currently the only place in the whole
    site where you can effectively “browse moderators”.  No doubt a page
    dedicated to doing just that will be added some time in a future release.
  • Sometimes your moderation searches may “time out” – just like normal
    searches (for tracks, etc) the search is cancelled if it’s still running
    after 30 seconds.  If this happens, try narrowing down your search,
    maybe by using the “moderation ID” filter (e.g. only where the ID is at
    least 530000).

Add Album

The manual “Add Album” pages now have “Guess Case” and “Guess Sortname”

Other Changes

Previously only two statistics were recorded for each moderator; a count of
“accepted moderations”, and one of “failed moderations”.
Now the “accepted” count has been split into two, one for auto-moderations,
and one for the rest; and the “failed” count has also been split into two,
one for “failed vote” moderations, and one for the other types of
failure.  For example, see your own profile page.

When moving an album to another artist, the original artist is no
longer shown in the search results (bug #576354).

Each moderation type has a name, and just to ensure that the name of each
type is unique, two of the types have been renamed.
Previously there were two types of “Add Track” (one used up to
17th August 2001, and one used thereafter); now the former is called
“Add Track (old version)”.
Additionally there are in fact two types both known as “Merge Albums” (one
for single-artist albums, and one for Various Artists).
The latter is now called “Merge Albums (Various Artists)”.

The “auto-notes” added by the Album Editor (e.g. “The first of a set
of 3 moderations”) were previously recorded against the moderator’s own
name; now, they are added by the ModBot.

If you use the “compact” album listing, then manually switch to a “full”
listing, the expand/collapse links now work, instead of switching you back
to a “compact” listing.

There is now a new moderation suggestions report, called “Superfluous Data
Tracks”.  Thanks to our script/report writer,
Matthias Friedrich, for
this.  This report lists albums which include a final “data track”,
but have no Disc ID.

Also in the are of suggestions reports: the “bad entries” report
now does HTML-escaping properly.  The “unknown” report also now does
this; it also runs much more efficiently, shows counts of how many tracks
and artists it found, and correctly includes the page footer.

Voting more than once on a moderation sometimes caused that moderation to
show up twice when it should not – this is now fixed (bug #829524).

New and Changed Documentation

Changes mainly of interest to MusicBrainz Server Programmers

Added help text to the INSTALL file and to, stating that
the current live SQL scripts must be used to import a live dataset.

RDFDump – the RDF dump file (link) is now valid XML. Previously it tried to
put long lines of hyphens (“—–” etc) within a comment (bug #829181).
