rsync - Jul 2009 - DO NOT REPLY [Bug 6588] New: errors missed when connecting to host with multiple addresses and host is down

https://bugzilla.samba.org/show_bug.cgi?id=6588

           Summary: errors missed when connecting to host with multiple
                    addresses and host is down
           Product: rsync
           Version: 3.0.6
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: arekm at maven.pl
         QAContact: rsync-qa at samba.org


I'm rsyncing from a IPv4 only machine to a machine with two addresses, one
IPv4
and one IPv6 visible in DNS.

When destination machine is down then I get this error:
rsync: failed to connect to buildlogs.pld-linux.org: Address family not
supported by protocol (97)
rsync error: error in socket IO (code 10) at clientserver.c(122) [sender=3.0.3]

so some errors were ignored instead of printing them.

How to reproduce, from ipv4 only machine, with ipv6 capable rsync and
getaddrinfo() run:

rsync /dev/null rsync://carme.pld-linux.org

which will end with:

rsync: failed to connect to carme.pld-linux.org: Address family not supported
by protocol (97)

while the missed error was:
16614 connect(3, {sa_family=AF_INET, sin_port=htons(2323),
sin_addr=inet_addr("193.239.45.140")}, 16) = -1 ECONNREFUSED
(Connection
refused)

Maybe rsync should print all errors it encounters when connecting iif
connection fails?

+ of course it should print which error is for which address being tried.

------- Comment #2 from wayned at samba.org  2011-01-01 16:00 CST -------
In 3.0.8 rsync will output all the errors when it fails to connect, and note
the associated address for each one.  e.g.:

  $ rsync carme.pld-linux.org::
  rsync: failed to connect to carme.pld-linux.org (193.239.45.140): Connection
refused (111)
  rsync: failed to connect to carme.pld-linux.org (::2001:6a0:13f:1:0:0):
Network is unreachable (101)
