Summary: rsync hang when using -H
Product: rsync
Version: 2.6.4
Platform: All
OS/Version: All
Status: NEW
Severity: major
Priority: P3
Component: core
AssignedTo: wayned@samba.org
ReportedBy: psfales@lucent.com
QAContact: rsync-qa@samba.org
After the upgrade to 2.6.4, we've found a number of cases where a command of
the
following form hangs:
./rsync -H user@remotemachine:/etc/remote_file /local/dir/
The problem goes away if -H is not used, or if the target is a file rather than
a directory. It also goes away when the local machine uses 2.6.3 (and the
remote machine uses either 2.6.3 or 2.6.4)
gdb shows that it is stuck in an infinite loop at link 196 in hlink.c:
while (!(file->flags & FLAG_HLINK_EOL)) {
ndx = file->F_NEXT;
file = FPTR(ndx);
}
Every time through the loop ndx is zero, and file always gets the same value.
Unfortunately, it doesn't seem to be reproducible between all pairs of
machines.
In the cases where we've seen it, the local machine is solaris and the
remote
machine is Linux running Fedora Core 2, or RedHat 9, but it doesn't show up
between all such pairs of machines. On the machines where the problem is
showing up, however, it is completely consistent and reproducible.
