Goldstein Lyor commented on SSHD-730:
-------------------------------------
Please clarify the problem some more - specifically what is meant by {quote}is
invalid because in can not be resolved properly in the context of the current
directory which symbolic link is referring to{quote}. Can you give a concrete
example ? Mainly
* What is the full path of server-side current directory that ".." should be
resolved against ?
* What is the full path of server-side symbolic link path that "../test/file"
should yield when resolved ?
* What is the expected result of resolving the symbolic link that
"../test/file" references ?
> Relative symbolic links with .. is not resolved properly by sftp readLink

> Key: SSHD-730
> URL: https://issues.apache.org/jira/browse/SSHD-730
> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 1.1.0, 1.2.0, 1.3.0
> Reporter: Lukas Waldmann
> Assignee: Goldstein Lyor
> Priority: Minor
>
> Using sftp to resolve symbolic links doesn't return proper resolution in case
> symbolic link contains ..
> Since version 1.1 the sendLink function of SftpSubsystem uses
> normalizedPath = SelectorUtils.normalizePath(unixPath, "/");
> to normalize path
> This function however return invalid path in case link contains ".."
> So for example if link is "../test/file" than normalizePath returns
> "test/file" which is invalid because in can not be resolved properly in the
> context of the current directory which symbolic link is referring to.
