Bug Description

[ Proposal ]
I'd like to upload glibc 2.26 today (September 5th) and aim to have all the autopkgtest regressions dealt with and the package migrated to the release pocket within a week.

[ Justification ]
Ubuntu's glibc is now two upstream revisions behind, and 2.25 and 2.26 brought in a large number of fixes and arch-specific optimizations. We want both.

[ Regression Potential ]
The upstream test suite passes on all of our architectures, and there are not too many changes noted in the upstream changelog that look like they'd cause disruption. A few obsolete headers have been removed and the like, so keeping an eye on future FTBFSes to potentially deal with that will be needed, but nothing looks hugely impactful.

[ Original Report ]
Request to upgrade to newest level of glibc 2.26. which introduced some new features for new machine...
Currently this version is under development


But should be availablle for the 17.10 Release

We cannot commit to upgradeing to 2.26 before it is released publically. At that point toolchain maintainers will evaluate if we can take new glibc in, or not. Usually we do, but it may slip depending on the end timings.

That has been fixed in more recent PPA versions. Also, who pointed you at that PPA? Installing random PPAs isn't usually smart. ;)

FFe approved. autopkgtests and archive rebuild tests give us a good deal of confidence about the quality of this landing, and we don't want to wait until 18.04 opens to get 2.26 in to get other feedback up the stack.

This bug was fixed in the package glibc - 2.26-0ubuntu1

glibc (2.26-0ubuntu1) artful; urgency=medium

  * Merge with current 2.26 from Debian experimental git, remaining changes:
    - Enable libc6{,-dev}-armel on armhf and libc6{-dev}-armhf on armel.
    - Heavily mangle the way we do service restarting on major upgrades.
    - Build i386 variants as -march=i686, build amd64 with -O3, and build
      ppc64 variants (both 64-bit and 32-bit) with -O3 -fno-tree-vectorize.
    - Build generic i386 flavour with -mno-tls-direct-seg-refs for Xen.
    - Drop the libc6-xen flavour, as the above change covers Xen's needs.
    - Enable systemtap support, which is currently disabled in Debian.
    - Don't build libc-l10n, its contents get stripped for language-packs.
    - Drop libc-bin manpages Recommends to Suggests to keep it in standard.
    - Revert dropping the ldconfig wrapper, xenial still has a lot of
      packages that don't ship a trigger but instead call in postinst.
    - Use DH_COMPAT=8 for dh_strip to fix debug sections for valgrind.
    - Mangle locales package to support Ubuntu language packs seamlessly.
  * debian/rules.d/build.mk: Configure with --enable-obsolete-nsl until we
    sort out a reasonable nsswitch migration strategy from compat to files.
