[External] Re: ctrl -c while executing --progress --size-only --partial results in unhidden but incomplete file

I'm suggesting a partial file that isn't hidden is worse.
Because any other app looking at the file would think the transfer is complete and try to use it.

It doesn't need to be a orphaned file,  when called next time with --partial rsync could re-opened the incomplete/hidden file, than it could  continue putting more bytes to the file until it was really completed.

When running in --partial mode, the filename wouldn't have to be random, instead it could be based on the source ip address, so that rsync knows what file to continue processing on.

That is what --partial does.  It keeps the partial file.  If it kept the
temporary file with the random file name that would just be a useless
orphaned file.
