Hi Bill, Such bugs are worth reporting upstream and once they're fixed there, we can pick it from there and provide it via the packages we ship, as exactly what Paride mentioned.
Since you don't want to open an issue upstream, maybe you'd like to use their mailing lists? cf: https://rsync.samba.org/lists.html That said, I am marking this as "Invalid" here because of the above reasons. Thanks! ** Changed in: rsync (Ubuntu) Status: Triaged => Invalid ** Changed in: rsync (Ubuntu) Status: Invalid => Won't Fix -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to rsync in Ubuntu. https://bugs.launchpad.net/bugs/1925381 Title: rsync conceals file deletions from reporting when --dry-run --remove- source-files are used together Status in rsync package in Ubuntu: Won't Fix Bug description: Rsync has an astonishing and dangerous bug: The dry run feature (-n / --dry-run) inhibits reporting of file deletions when --remove-source-files is used. This is quite serious. People use --dry-run to see if an outcome will work as expected before a live run. When the simulated run shows *less* destruction than the live run, the consequences can be serious because rsync may unexpectedly destroy the only copy(*) of a file. Users rely on --dry-run. Although users probably expect --dry-run to have limitations, we don't expect destructive operations to be under reported. If it were reversed, such that the live run were less destructive than the dry run, this wouldn't be as serious. Reproducer: $ mkdir -p /tmp/src /tmp/dest $ printf '%s\n' 'yada yada' > /tmp/src/foo.txt $ printf '%s\n' 'yada yada' > /tmp/src/bar.txt $ cp /tmp/src/foo.txt /tmp/dest $ ls /tmp/src/ /tmp/dest/ /tmp/dest/: foo.txt /tmp/src/: bar.txt foo.txt $ rsync -na --info=remove1 --remove-source-files --existing src/* dest/ (no output) $ rsync -a --info=remove1 --remove-source-files --existing src/* dest/ sender removed foo.txt $ ls /tmp/src/ /tmp/dest/ /tmp/dest/: foo.txt /tmp/src/: bar.txt (*) note when I say it can destroy the only copy of a file, another circumstance is needed: that is, rsync does not do a checksum by default. It checks for identical files based on superficial parameters like name and date. So it's possible that two files match in the default superficial comparison but differ in the actual content. Losing a unique file in this scenario is perhaps a rare corner case, but this bug should be fixed nonetheless. In the typical case of losing files at the source, there is still a significant inconvenience of trying to identify what files to copy back. Note this bug is similar but differs in a few ways: https://bugzilla.samba.org/show_bug.cgi?id=3844 I've marked this as a security vulnerability because it causes unexpected data loss due to --dry-run creating a false expectation.
