With the next push you'll see the first new glibc version for rawhide
(2.8.90-1). This version has quite a few changes, most prominently
changes to getaddrinfo.
The new implementation should be faster since it parallelizes DNS
lookups and avoids code duplication in many other cases. But the DNS
optimization is also what I'm a bit concerned about. I tested the code
with a local bind daemon and all works well. What I haven't done is
testing it with other DNS servers.
Everybody should look out for changes in the host name resolution.
There shouldn't be any but who knows.
Those who are using DNS servers other than bind might want to give the
code bounding. Especially also the fallback code to issue lookups with
TCP (you can force this by setting the RES_USEVC bit in _res.options,
