[Bug 1965076] Re: rsync --update incorrectly reports file "is newer" than itself

[Simon Déziel]

@Ian, the back and forth on status was apparently due to a simple
mistake on which distro version was affected. The good news is that
thanks to comment #7, we now know that Kinetic is fixed which is one of
the required step to do a SRU
(https://wiki.ubuntu.com/StableReleaseUpdates) to have the fix land in
Jammy.

Title:
  rsync --update incorrectly reports file "is newer" than itself

Status in rsync package in Ubuntu:
  Confirmed

Bug description:
  rsync 3.2.3 has a broken "--update" option.    See the examples below.
  The "--update" option incorrectly makes rsync say a file is newer than itself.
  Remove the "--update" option, and rsync correctly says the file is "uptodate".
  The right output should of course be "is uptodate" in all cases.
  This bug also shows up between machines if the source rsync is 3.1.3 and the destination is 3.2.3.
  The bug does not show up if the source rsync is 3.2.3 and the destination is 3.1.3.

  $ touch foo
  $ rsync -avv --update foo .
  delta-transmission disabled for local transfer or --whole-file
  foo is newer                 <=== THIS IS NOT CORRECT - A file can't be newer than itself.
