             Bug #: 13375
           Summary: nscd inhibits HOSTALIASES envvar
           Product: glibc
           Version: 2.14
            Status: NEW
          Severity: normal
          Priority: P2
         Component: nscd
        AssignedTo: drepper.fsp@gmail.com
        ReportedBy: matz@suse.de
    Classification: Unclassified


Make sure nscd is running and indeed caching hosts database lookups (not the
case with debian for instance), then:

% HOSTALIASES=./fooalias strace getent hosts bla 2>&1 | grep fooalias

shows that the file isn't accessed.  It is accessed if nscd isn't running
(and in that case is correctly interpreted).  getent is just a convenient
shorthand for a testcase, the gethostbyname interface behaves the same,
i.e. doesn't lookup HOSTALIASES files when nscd is running.  But according
to the manpage it should.  I think it's an extension, not POSIX behaviour,
but one side needs to be fixed, either docu or code.

FWIW, the environment variable isn't respected because res_hostalias
isn't called, because __libc_res_nquery isn't called, because the
nscd-accessing routines are called first.
