           Summary: rsync remove-source-files and opened file
           Product: rsync
           Version: 3.0.6
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: core
        AssignedTo: wayned at samba.org

Hi,
when I use option remove-source-files and source files is opened and growing
rsync copy partial source file and after copying remove it even though in time
after copying the files are different

I suggest to check difference after file is copying and if source and
destination are different don`t remove the source file

next improve is to setup options like remove-source-file-delay to setup some
time after copying to check difference between source and destination and
remove source only if the files are the same

next improve is to setup options like remove-source-file-loop to setup numbers
of loop to try if source file was already closed 
if remove-source-file-loop=0 it will be forever

I hope this scenario could be implemented independently on OS and help many
people to use rsync for opened files.
peter

While the user should not be getting themselves into this situation (if
they're
smart about it), it is good for rsync to help the user not shoot themselves in
the foot.  I have made rsync re-stat the file and skip the remove if the size
or mtime is different.

This will be fixed in 3.1.0.  I've also added some helpful hints in the
manpage
on how best to use --remove-source-files.
