> FtpFileObject.getChildren() fails when a folder contains a file with a colon in the name
> ----------------------------------------------------------------------------------------
>
> Key: VFS-398
> URL: https://issues.apache.org/jira/browse/VFS-398
> Project: Commons VFS
> Issue Type: Bug
> Affects Versions: 2.0
> Environment: Connecting via FTP to a host running SunOS 5.10
> Reporter: Mark Leonard
> Assignee: Otto Fowler
> Priority: Blocker
> Attachments: VFS-398-gg-00.patch

> In line 767 of DefaultFileSystemManager.java the UriParser's extractScheme() method is called:
> String scheme = UriParser.extractScheme(buffer.toString());
> This code was added in revision 780730
> http://svn.apache.org/viewvc?view=revision&revision=780730
> It is not clear to me why this change was made.
> For the FTP provider, buffer contains a plain file name (i.e. without a path and definitely not in URI form)
> A colon is a valid character for a file name.
> However a colon will be interpreted as a URI scheme name.
> This causes an exception when the resolved path is checked using AbstractFileName.checkName()
> Sample code:
> FileObject fo = VFS.getManager().resolveFile("ftp://user:pass@host/some/path/some.file");
> fo.getParent().getChildren();
> If /some/path/ contains a child such as PREFIX:SUFFIX then an exception is thrown:
> Exception in thread "main" org.apache.commons.vfs2.FileSystemException: Invalid descendent file name "PREFIX:SUFFIX".
> at org.apache.commons.vfs2.impl.DefaultFileSystemManager.resolveName(DefaultFileSystemManager.java:791)
> at org.apache.commons.vfs2.provider.AbstractFileObject.getChildren(AbstractFileObject.java:710)
> at org.apache.commons.vfs2.provider.ftp.FtpFileObject.getChildren(FtpFileObject.java:420)
> Therefore calling code is unable to list the children of the specified folder.
