Paul commented on VFS-398:
--------------------------
As a user of the API, this is in the context of FtpFileObject.getChildren() so
it is not possible to percent-encode. From Mark's findings, it looks like this
is a major bug that has to be fixed internally right?
> 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
> Priority: Blocker
> Fix For: 2.0
>
>
> 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.
