Server update, 2016-02-08

This update hopefully fixes some issues with “Edit Medium” edits that, in rare cases, resulted in an incorrect track listing. Sometimes tracks were being inexplicably deleted. The git tag for today’s release is v-2016-02-08.

Bug

  • [MBS-8752] – Database inconsistencies when updating medium
  • [MBS-8765] – instrument_annotation should not be backed up in mbdump.tar.bz2
  • [MBS-8770] – Banner not displayed

Task

  • [MBS-7475] – Get rid of Algorithm::Merge

Server update, 2016-01-25

Backwards-Incompatible JSON Web Service Changes

In an effort to get our JSON Web Service out of “beta” status, we’ve made some backwards-incompatible changes to it in this release:

  • The video flag on recordings is now outputted as true or false instead of 1 or 0.
  • Empty relations arrays are not outputted for linked entities anymore, since linked entities never include relationships.
  • The iso_3166_1_codes, iso_3166_2_codes, and iso_3166_3_codes properties have been renamed to iso-3166-1-codes, iso-3166-2-codes, and iso-3166-3-codes, respectively. This only applies to lookup and browse requests; search requests already outputted these with hyphens.
  • The iso-3166- properties mentioned in the previous point are not outputted if they’re empty.

Some other changes to the web service have been made, but are considered additions (not changes to existing output), so hopefully shouldn’t cause any problems. You can review them in the changelog below.

Other Changes

An issue where entities deleted from the database (but still present in the cache) remained visible has hopefully been fixed. There are several other miscellaneous bug fixes linked below. Thanks again to Ulrich Klauer for his contributions. The git tag is v-2016-01-25.

Bug

  • [MBS-5676] – JSON relationships output doesn’t include target-type
  • [MBS-6166] – Deleted accounts can still have details edited
  • [MBS-7241] – Non-transactional cache means the cache can sometimes fail to delete entities that are gone at the database level
  • [MBS-7735] – ws/2: recording’s “video” flag inconsistent between xml and json
  • [MBS-7921] – Internal server error when requesting /ws/2/isrc as JSON
  • [MBS-8367] – ws2 JSON incorrectly returns non-included field as null value
  • [MBS-8396] – JSON output has no ordering key attribute for release group series
  • [MBS-8563] – Release & Release Group browse requests without type/status filters return results which contradicts the documentation
  • [MBS-8688] – Random tagged entity type display inconsistency in personal tag page
  • [MBS-8722] – Edit stuck trying to change the gender of a group
  • [MBS-8726] – Replicated updates don’t invalidate cache entries on slave servers
  • [MBS-8730] – Reordering of sub work parts causes unwanted reordering of main work parts
  • [MBS-8746] – JSON web service doesn’t distinguish between relationships not existing vs. not being loaded

Server update, 2016-01-11

Our first release of 2016 consists mainly of data-display fixes by Ulrich Klauer and a couple small improvements by Google Code-In students Caroline Gschwend and Ohm Patel. Notably, internationalized domain names are now displayed in decoded form: https://musicbrainz.org/url/2de1616a-7ca0-4688-92cc-0a8373190ede

  • [MBS-8709] – Mark up removed entities as usual in add medium/edit medium edits
  • [MBS-8713] – Block SoundCloud search and tags URLs

Server update, 2015-12-28

A new feature in today’s release is a list of recent notes left on your edits (accessible from the menu in the upper-right corner of the page: “My Data” -> “Notes Left on My Edits”).

Users will be notified in a banner message whenever they receive a new edit note, and be linked to that page. Hopefully this will improve communication with people who aren’t seeing their emails.

We also have a number of bug fixes/improvements from Ulrich Klauer and several Google Code-In students: Caroline Gschwend, Ohm Patel, and Stanisław Szcześniak. Thanks for all your work!

The git tag is v-2015-12-28 and the changelog is below.

Bug

  • [MBS-7572] – Edit work alias is not showing the sort name loss
  • [MBS-7873] – Edit search for editor causes editor name to be listed twice in recent items
  • [MBS-7882] – Strange empty parens after alias name on edits

  • [MBS-8381] – Some symbols are double-encoded in inline search
  • [MBS-8414] – Ended flag is not correctly handled in edits
  • [MBS-8635] – Untranslatable strings
  • [MBS-8690] – “Add artist” edit can’t be rejected if the artist has subscriptions
  • [MBS-8691] – “Edits for subscribed editors” page timing out
  • [MBS-8702] – Page title shows “"”
  • [MBS-8705] – HTML code shown in edit summary

Improvement

  • [MBS-4565] – Search for Edits by editor notes.
  • [MBS-7070] – Missing icon (small version) for area, place and work
  • [MBS-8482] – “Add Disc” button in editor should be renamed to “Add Medium” or “Add Tracklist”
  • [MBS-8504] – Edits mandated by editing interface should be auto-edits

  • [MBS-8657] – Update the flag of Libya
  • [MBS-8672] – Update the flag of Lesotho
  • [MBS-8673] – Update the flag of Myanmar

Server update, 2015-12-14

  • The edit listings for your subscribed entities (and subscribed editors) now shows all edits entered within the past 7 days, by default (so, auto-edits are now visible, plus edits that may have passed by vote before you saw them). There’s a new toggle-able option on the page to only display open edits, to restore the previous behavior while voting. We’ll hopefully introduce some way to mark closed edits as reviewed/dismissed soon, to make the listings easier to digest.
  • Edit histories for large collections should hopefully load a bit faster now. Please comment on MBS-8368 if you have a collection that still consistently times out when viewing its edit history.

We’ve also made a slight change to our release process. Previously, our master branch was our “stable” branch which pointed to the most recent release (i.e., the code we run on musicbrainz.org itself). If this is what you expect, you should now be using the production branch instead. The master branch has become our main development branch, which means it may be slightly less stable from now on (of course, we’ll do our best to avoid that).

Thanks to Ulrich Klauer (chirlu) for his contributions to today’s release.

The git tag is v-2015-12-14 and the complete changelog is below.

Bug

  • [MBS-7012] – Join phrase cleanup not running
  • [MBS-8145] – Internal server error loading collection edits
  • [MBS-8368] – Edit queries for large collections time out
  • [MBS-8647] – “Edits for subscribed entites” doesn’t show auto-edits
  • [MBS-8660] – Editors can’t delete their location
  • [MBS-8661] – Adding and editing non-ended areas is broken

New Feature

  • [MBS-8664] – Show “last login/active date” somewhere on /user/ for account administrators

New search server build deployed

Today we’ve deployed a new build of the search server code. As you may know, we’ve been having loads of issues with our search servers recently.

In an effort to figure out what causes the bizarre behaviour we’ve observed, we compiled a new version of the codebase with a more recent version of Lucene. In theory this makes no feature changes to the codebase, but you never know if that is actually the case.

We hope that this build will be more stable, but we’ll need to observe over the next few days to see if that will be the case. If you spot any problems, please report them in our SEARCH bug tracker.

Thanks!

Server update, 2015-11-30

The major updates in today’s release are:

  • Non-auto-editors can make auto-edits to their release additions within 1 hour of adding them.
  • There’s a way to report editors for bad behavior, from their user profiles. The reports will be sent to our account admins. We’d prefer people use this method from now on for reporting unresponsive editors, or for any Code of Conduct violations. Account admins have also received an easy way to restrict a user’s editing/voting capabilities.
  • Auto-editors can change a release’s data-quality level via auto-edit. Previously, this was always put to a vote. We still don’t display release quality as well as we could (currently it’s only visible in the release sidebar). Low-quality releases can be found via our edit search, though.
  • Everyone can enter “Add recording” and “Remove alias” edit types as auto-edits.
  • Edits to events can be searched via our edit search interface (thanks chirlu).

There were a lot of comments on last release’s blog post saying that it’s harder to review release additions now that they’re auto-edits, and worrying about database quality suffering due to this. The next server release should allow showing auto-edits entered within the most recent voting period (7 days) in your subscribed editor/entity edit listings (MBS-8647), and hopefully a way to hide auto-edits you’ve reviewed from these lists (MBS-8654) to get them out of your way. I hope these and future changes can strike a balance between allowing people to see and remove releases that are clearly wrong or non-existent, vs. encouraging merging/fixing existing releases rather than voting them down.

The git tag for today’s release is v-2015-11-30 and the complete changelog is below.

Bug

  • [MBS-8460] – Add to collection link on entity page doesn’t show the collection name
  • [MBS-8636] – Adding duplicate entities to a series causes an internal server error
  • [MBS-8639] – Instrument merge gives ERROR: duplicate key value violates unique constraint “link_attribute_pkey”
  • [MBS-8641] – Release editor breaks with “error: 0” if a submitted edit throws a NoChanges exception
  • [MBS-8648] – Historic relationship edits no longer display the source entity

Improvement

  • [MBS-1880] – Allow an editor to apply edits without voting within a short timeframe after his/her ‘add release’
  • [MBS-8208] – Add a way to report a user to an admin
  • [MBS-8271] – Add a way to prevent a user from editing/voting which doesn’t involve removing the email address

New Feature

  • [MBS-8645] – Allow searching for edits to events

Task

  • [MBS-8385] – Make change release quality edits auto-edits for auto-editors
  • [MBS-8386] – Make add recording edits auto-edits for everyone
