Upcoming upload of glibc 2.39 in noble-proposed

Hi folks!

As usual in this time of the cycle, the new version of glibc is about to
be released upstream (scheduled next Thursday, Feb 1st), and should thus be
uploaded to the archive shortly thereafter, presumably around Feb 7th.

Have a look at the upstream changelog if you're interested in the

Note that we are not impacted by the libcrypt removal as we
haven't built libcrypt for glibc for a while. If some of your projects
use a third-party malloc implementation, see at bottom to try a

A number of potential issues have already been identified through a test
rebuild done with a development snapshot of glibc. All glibc-related
regressions have been identified and reported (thanks to Ravi Kant
Sharma for his tremendous help on that front), and we're currently
working our way through the list:

There's a fresh snapshot package available in a PPA:

(i386 build is currently broken, WIP)

This upload usually has the immediate consequence of blowing up the
autopkgtest huge queue, meaning any other package that uses this queue
for its rdep tests will be directly impacted. In addition, the added
load usually means there's a higher failure rate on tests (e.g. timeouts
due to resource attrition). Furthermore, it is possible that a package
built after the glibc upload would pick up a versioned dependency on the
newer glibc due to changes in ABIs for existing functions. In that case,
said package would need to wait until glibc has migrated, which can take
a little while.
