Summary: DirectoryInfo.GetDirectories() does not return sym links
that point to directories.
Product: Mono: Class Libraries

URL: http:///
OS/Version: Linux
Status: NEW
Severity: Minor
Priority: P5 - None

Description of Problem:
When running DirectoryInfo().GetDirectories() on a directory that contains
symbolic links to other directories, those links are not included amongst the
DirectoryInfo [] returned.
Steps to reproduce the problem:
1. Create and compile the following C# test program.
<C# "symbLinks.exe">
using System;
using System.IO;
namespace symLinks
{
class Program
{
public static void Main(string[] args)
{
DirectoryInfo di = new DirectoryInfo(Environment.CurrentDirectory);
DirectoryInfo [] dirs = di.GetDirectories();
FileInfo [] files = di.GetFiles();
Console.WriteLine("List of Directories:");
foreach(DirectoryInfo dir in dirs)
Console.WriteLine(dir.Name);
Console.WriteLine("\nList of Files:");
foreach(FileInfo file in files)
Console.WriteLine(file.Name);
}
}
}
</C#>
2. Create a test directory on Linux, containing some directories, symbolic
links and files. e.g.
# cd
# mkdir test
# cd test
# mkdir dir1
# ln -s dir1 symLink1
# : > file1
3. Move the compiled C# program to the directory, and run it.
Actual Results:
List of Directories:
testDir1
List of Files:
file1
symLinks.exe
symLink1
Expected Results:
List of Directories:
testDir1
symLink1 <--- Expected the symLink1 to appear as a directory
List of Files:
file1
symLinks.exe
symLink1 <--- Not sure if symLink1 should appear as a file
How often does this happen?
Always, when handling symbolic links on Linux.
Additional Information:
The C# program was targeted for NET 2.0.
Interestingly, symbolic links are seen as directories when accessing those same
files from Windows via a samba share, so I guess Samba does some clever
translation.
This might be related to closed BUG #322588
(https://bugzilla.novell.com/show_bug.cgi?id=322588). From my reading of that
discourse, the expectation of seeing the symbolic link appear as a directory is
not unreasonable, (see last comment from "Alex"). That bug was reported fixed
as far back as r67766. Has there been a regression?
