rsync - Nov 2011 - [Bug 8558] New: rsync --out-format doesn't support single character escapes as listed in manpage

https://bugzilla.samba.org/show_bug.cgi?id=8558

           Summary: rsync --out-format doesn't support single character
                    escapes as listed in manpage
           Product: rsync
           Version: 3.0.6
          Platform: x64
        OS/Version: Linux
            Status: NEW
          Severity: minor
          Priority: P5
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: kym.newbery at aad.gov.au
         QAContact: rsync-qa at samba.org


According to the rsync manpage, the --out-format <FORMAT> switch supports
the
single character escapes listed under the 'log format' options in
rsyncd.conf
manpage, however for my version of rsync some of the escapes don't work.

In this specific case : %a, %h, %P, %u are not expanded.

example :

[tiris at sts-dev tg_sync]$ rsync -tr -v --out-format "%a %b %B %c %f %G %h
%i %l
%L %m %M %n %o %p %P %t %u %U"  rsync://user at tg-b1.aad.gov.au/log
/cifs/tiris/tg-b1

This is how rsync displays a value that is null (undefined) -- it displays the
escape that is not defined.  In all the escapes you cited, they are you defined
in a daemon, so the non-daemon side has no data to output for them.  If you use
them in the daemon's output, they would display the expected information.

So, is the current practice the right one?  I want rsync to display something
for an undefined field, since displaying nothing at all can make the parsing of
the columns not match up right.  We could have it display "(null)" or
"<empty>"
or some such value, which might be better.

My expectation was that for the non-daemon rsync,  the %a and %h would indicate
the remote IP (if one) was being used, which was useful in the situation where
I am performing a pull rsync with a non-daemon rsync from many remote systems
(running the daemon) to one local repository.  currently I'm having to emit
the
host name in the bash script that rsync is working with. 

eg 

(for loop)
echo $HOST
rsync -tr -v --out-format rsync://user@$HOST/log <dest>
(end loop)

It's not a biggie.. I just thought the %a and %h in the --out-format could
do
that automatically for me.

I'm not sure what might be work emitting if the value is empty.. besides
perhaps making the distinction in the manpages a bit clearer as to which is
supported in daemon and non-daemon.
