Bug#829145: transition: glibc 2.23

[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 2.23. It is currently
available in experimental and has been built successfully on all
official architectures except hurd-i386. We have fixed the hurd-i386
failure in out git, and we are working on build failures for alpha, hppa
and sparc64. There are due to testsuite issue, mostly in the math parts
and do not look very critical.

It should be noted that this upload will make a few packages to FTBFS,
mostly due to more precise checking in the floating-point classification
macros (isnan, isinf, ...). In most of the cases the changes just make
existing bugs visible. The list of affected packages is available [1]
(thanks to Martin Michlmayr), and the bugs have been opened for more
than 3 months.

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.]* \(<< 2.24\)/;
is_bad = .depends ~ /libc[0-9.]* \(<< 2.23\)/;

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, namely the fts64_* and the lgamma* ones. It should not
concerns many packages.

Thanks for considering,
Aurelien
