rsync - Mar 2008 - DO NOT REPLY [Bug 5304] New: failed to set times (symlinks)

https://bugzilla.samba.org/show_bug.cgi?id=5304

           Summary: failed to set times (symlinks)
           Product: rsync
           Version: 3.0.0
          Platform: All
        OS/Version: Mac OS X
            Status: NEW
          Severity: normal
          Priority: P3
         Component: core
        AssignedTo: wayned@samba.org
        ReportedBy: gmoreno@wlu.ca
         QAContact: rsync-qa@samba.org


Hello,

Among the enhancements to version 3.0.0 you state this:

    - If we get an error setting the time on a symlink, we don't complain
about
      it anymore (since some operating systems don't support that, and
it's not
      that important).

However, after version 3.0.0pre7 I started getting this error:
rsync: failed to set times on "some_link_to_another_file": Permission
denied
(13)

where the error happens whenever the file is a soft link to a "proper"
file. I
know this is minor, but has me verifying perfectly successful transfers.

This is happening under MacOSX tiger, leopard, with powerpc or intel processors
(does not matter), and several Linuxes with different processors, meaning
something changed between pre7 and pre8 that overlooked this enhancement.

Best,
   GM

------- Comment #1 from wayned@samba.org  2008-03-05 17:22 CST -------
The main problem is that OS X returns an inane errno, EPERM, instead of a sane
one, ENOSYS.  If possible, complain to Apple's bug tracker about this issue
and
its kin (e.g. EPERM being returned when trying to access a extended attrs of a
device, etc.).

The only error that rsync ignores these days when trying to set the time of a
symlink is ENOSYS, and that will remain the same.  You can avoid the error by
commenting out the HAVE_LUTIMES define (note the "L") in config.h.

Some work could be done with configure to avoid setting that define, but I'm
more inclined to try to get Apple to make their functions return proper errno
values.  (However, that's a soft stance, that may change.)
