Summary: --dry-run output inaccurate due to implied symlink
Product: rsync
Version: 2.6.9
Platform: Other
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P3
Component: core
AssignedTo: [EMAIL PROTECTED]

When a symlink has contents in the file list (which happens for implied
symlinks from --relative), rsync's dry-run output can be inaccurate because it
naively tries to follow the symlink when processing the contents, even though
it has not actually created the symlink.
I reproduced this as follows in an empty directory:
$ mkdir -p src/a dest/a
$ ln -s a src/b
$ echo data >src/a/foo
$ rsync -a src/a/ dest/a/
$ find . -ls

1879989 0 drwx------ 3 matt matt 96 Feb 25 12:07 ./src
1880376 0 drwx------ 2 matt matt 72 Feb 25 12:08 ./src/a
1880793 4 -rw------- 1 matt matt 5 Feb 25 12:08 ./src/a/foo
1880792 0 lrwxrwxrwx 1 matt matt 1 Feb 25 12:07 ./src/b -> a
1880779 0 drwx------ 3 matt matt 72 Feb 25 12:07 ./dest
1880784 0 drwx------ 2 matt matt 72 Feb 25 12:08 ./dest/a
1880794 4 -rw------- 1 matt matt 5 Feb 25 12:08 ./dest/a/foo
$ rsync -ni -a --relative src/./b/foo dest/
cL+++++++++ b -> a
>f+++++++++ b/foo
$ rsync -i -a --relative src/./b/foo dest/
cL+++++++++ b -> a
Notice that rsync itemized creation of b/foo on the dry run but not on the real
run.
I tried to test this with the current CVS rsync, but it hung on the dry run,
which probably indicates a separate bug.
