Bug#939048: transition: glibc

Package: release.debian.org
Severity: normal

Dear release team,

I would like to get a transition slot for glibc 2.29. It is available in
experimental for a bit more than 2 weeks and there is no known issue or
regression. It has been built successfully on all release architectures
and most ports architectures. It fails to build on alpha, ia64 and
sparc64 due to a few testsuite issues that are being investigated or
need to be investigated and which do not looks really worrying. It
doesn't build on kfreebsd-*, but this has been the case for a few
glibc releases already.

As 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 (some packages only on some architectures):
 - apitrace
 - bro
 - dante
 - gcc-9
 - gcc-snapshot
 - glibc
 - libnih
 - libnss-db
 - unscd

Ben file:

Here is the corresponding ben file:
  title = "glibc";
  is_affected = .depends ~ /libc[0-9.]* \(<</;
  is_good = .depends ~ /libc[0-9.]* \(<< 2.30\)/;
  is_bad = .depends ~ /libc[0-9.]* \(<< 2.29\)/;

In addition a few new symbols have been added that might prevent a few
other packages to migrate to testing until glibc migrates if they pick
up the new symbols. Those are posix_spawn_file_actions_addchdir_np,
posix_spawn_file_actions_addfchdir_np, getcpu, exp, exp2, log, log2 and
pow. The math functions are probably used by quite a few packages.

Thanks for considering.
