Bug#817003: transition: glibc

[Aurelien Jarno <aurel32@debian.org>]

Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: transition

Dear release team,

We would like to get a transition slot for glibc 2.22. It is currently
available in experimental and has been built successfully on all
official architectures except hurd-i386. We have fixed the alpha and
hurd-i386 failures in our git, and we believe the hppa, sparc64 and
x32 issues are due to a misconfiguration of the experimental chroots
(the default compiler in the chroots is gcc-6). Therefore the next
upload should build everywhere.

As the glibc is using symbol versioning, there is no soname change. That
said a few packages are using libc internal symbols and have to be
rebuilt for this transition:
- apitrace
- bro
- dante
- libnih
- libnss-db
- unscd

Here is the corresponding ben file:

title = "glibc";
is_affected = .depends ~ /libc[0-9.]* \(<</;
is_good = .depends ~ /libc[0-9.]* \(<< 2.23\)/;
is_bad = .depends ~ /libc[0-9.]* \(<< 2.22\)/;

In addition to that, a few new symbols have been added that might
prevent a few other packages to transition to testing if they pick up
the new symbols. They are very few of them, however packages built with
"-fopenmp -ffast-math" might pick a dependency on the new libmvec
library on amd64 and x32.

Thanks,
Aurelien
