A customer reported an incorrect behavior on the arv-put command when used with --no-follow-links:

$ arv-put --no-follow-links /path/to/some-dir/


$ arv-put --no-follow-links /path/to/some-dir/*

Should produce the same collection, but if /path/to/some-dir/ has some symbolic links inside, the second execution will not ignore them.

#3 Updated by Tom Clegg 1 day ago

Code LGTM.

Which behavior is "correct" seems debatable: it might be surprising that "arv-put --no-follow-symlinks foo" just creates an empty collection if foo itself is a symlink.

Perhaps worth adding something to the --help message to clarify?

-Do not follow file and directory symlinks.                                                                                                                       
+Do not follow file and directory symlinks. Even paths given explicitly on the command line will be skipped if they are symlinks.
