[Bug 1589644] Re: [SRU] biber 2.4 to xenial

[Nick Andrik]

Hi Locutus,

Thanks for sponsoring the upload.
No need to have one with my own signature, what you uploaded is fine :)

After this version is released, we should also close Bug 1565842
We can do it manually, or include it in the changelog, your call.

Regards,
Nick

Title:
  [SRU] biber 2.4 to xenial

Status in biber package in Ubuntu:
  Fix Released
Status in biber source package in Xenial:
  Fix Committed

Bug description:
  Please SRU biber 2.4 to xenial.

  [Impact]:
  ========================
  Current biber version in xenial (2.3) is too old for texlive-bibtex-extra version (2015.20160320-1), as described in Bug 1565842 , making biber uninstallable in xenial.
  Backporting the most recent version (2.5) would still be a mistake since it requires a (>>= 2016) version of texlive-bibtex-extra.
  The proper solution is to backport the 2.4-1 version as was seen in debian.
  This has been verified to function properly in the aforementioned bug.

  The bug has attracted a lot of attention with 68 people marked as
  affected as of June 13. It may meet the criteria for "High" severity
  since it "Has a severe impact on a small portion of Ubuntu users
  (estimated)" and "Prevents the application or any dependencies from
  functioning correctly at all".

  [Changes]:
  ========================
  2.4    (2016-03-01)
         * Misc bug fixes
         * There is now a 64-bit windows build built on windows 10
         * Biblatexml datasources now support sourcemapping and have a schema
           automatically generated from the datamodel. See new biber options
           'validate-bltxml' and 'no-bltxml-schema' in --help output.
         * New functionality in sourcemaps for creating new entries and
           looping over specified fields.
         * Sorting key used to sort names is now customisable. See
           \DeclareSortingNamekeyScheme in biblatex manual.
         * Support for Zotero RDF/XML and Endnote removed. These were
  experimental and messy.

  [Test Case]:
  ========================
  Mark off items in the checklist [X] as you test them, but please leave the checklist so that backporters can quickly evaluate the state of testing.

  The original 2.4-1 version from debian/snapshot can be found here:
  http://snapshot.debian.org/package/biber/2.4-1/

  The PPA build that was used for testing can be found here:
  https://launchpad.net/~andrikos/+archive/ubuntu/ppa/+packages?field.name_filter=&field.status_filter=published&field.series_filter=xenial

  Probably, you can test-build the backport in your PPA with backportpackage:
  $ backportpackage -u ppa:andrikos/ppa -s xenial -d xenial biber

  * xenial:
  [X] Package builds without modification
  [X] biber installs cleanly and runs

  [Regression Potential]:
  ========
  The following reverse-dependencies need to be tested against the new version of biber. For reverse-build-dependencies (-Indep), please test that the package still builds against the new biber. For reverse-dependencies, please test that the version of the package currently in the release still works with the new biber installed. Reverse- Recommends, Suggests, and Enhances don't need to be tested, and are listed for completeness-sake.
