Package: rsync
Version: 3.1.0-2
Severity: normal
Dear Maintainer,
rsync fails to remove source files with --remove-source when those are
symlinks whose referents are transferred with the --copy-links (-L) option.
rsync returns the error:
ERROR: Skipping sender remove for changed file: […]
Steps to reproduce:
1. Create a set of files, some of which are symlinks with
valid referents.
marc@defiant:~$ cd $(mktemp -d)
marc@defiant:/tmp/tmp.L4VQqyIk11$ mkdir -p orig/src dst
marc@defiant:/tmp/tmp.L4VQqyIk11$ date > orig/src/A
marc@defiant:/tmp/tmp.L4VQqyIk11$ date > orig/B
marc@defiant:/tmp/tmp.L4VQqyIk11$ ln -s /tmp/tmp.L4VQqyIk11/orig/B orig/src/
marc@defiant:/tmp/tmp.L4VQqyIk11$ ls -l orig/src/
total 4
-rw-rw-r-- 1 marc marc 29 Dec 15 21:17 A
lrwxrwxrwx 1 marc marc 26 Dec 15 21:17 B -> /tmp/tmp.L4VQqyIk11/orig/B
marc@defiant:/tmp/tmp.L4VQqyIk11$ ls -lL orig/src/
total 8
-rw-rw-r-- 1 marc marc 29 Dec 15 21:17 A
-rw-rw-r-- 1 marc marc 29 Dec 15 21:17 B
2. Copy those files with rsync, using the option --remove-source to
remove the successfully transferred source files and --copy-links (-L)
to copy the symlink referent instead of the symlink.
marc@defiant:/tmp/tmp.L4VQqyIk11$ rsync -aL --remove-source-files orig/src/
dst/
ERROR: Skipping sender remove for changed file: B
Actual result: rsync throws an error and does not remove the source
if it is a symlink.
Expected result: rsync should delete the symlink.
The mtime of the destination file matches the mtime of the source file
(the symlink referent). It does not match the mtime of the symlink. I
think the rsync error message hints at the symlink mtime. Symlink mtimes
are irrelevant and should probably not be used here.
