I glanced the tests you have in place for uris and naming
and they seem extensive. I am not going to test this extensively.
But the case that brought this issue up was like the following
I called
FileObject resolveFile(File baseFile, String name)
on FileSystemManager
and the baseFile has path som

Hi Mario & Wouter,
Could you still clarify what is the purpose of making
a relational database work as filesystem.
This is just for curiosity (and maybe good for docs).
I had the idea that someone might want to attach
more metadata to files through attributes.
Another reason that came to my mind

> (the easy part)
I would see the mapping from relational model to filesystem:
relation (table) = filesystem (defines a set of files that share the same set
of attributes).
tuple (row) = file that has the content value and attribute value
I wrote the previous email too quickly
so there are many errors in details.
So please read it without too much attention to the details.
I quess those uris with non us characters get always
sent in some encoding.
It would work nicely if it could be us-ascii
But the interpretation problem is just li
Again quoting the RFC:

For original character sequences that contain non-ASCII characters,
however, the situation is more difficult. Internet protocols that
transmit octet sequences intended to represent character sequences
are expected to provide some way of identifying the charset used, if
th
URI spec dudes talk about canonical form of the URI.
This is left for the schema to define.
Now if vfs is in control of the uri's that come in and go out
then it would be possible to canonicalize the URI when it enters
the core areas of vfs that is not provider (schema) specific.

The reason is simple. It does not work.
I don't know why. So I think we should use

which characters to include as special ones.

Hi binkley,
I had (maybe 1 year ago) a fairly big contribution vfs
that was rejected because it used 1.4 regex package.
So I basically am for your your suggestion.
Nevertheless I don't think the reason should be that
because of Sun's business plans Open Source community
should make it's decisions.

t would be nice if FileSystemManager interface would dictate at
least some kind of configuration framework so the ant tasks would not have to
mention any implementations.

That is a shame. But isn't it so that we should first come up with
a configuration structure
Here are some small changes that I came across when making the changes compilable.
I changed configure method to init because there was already
private configure(String)
method in DefaultFileSystemManager but the existing init method
was without arguments.
I saw also that there is quite a lot of

What happens if FileSystemManager is not closed and JVM exits.
In other words what does close method do?
And is it a problem if there are many FileSystemManagers?
This can happen when instantiating outside of VFS class.
Can there be any problems if Ant task uses one manager instance and
some other
I have pronlems with VfsTask.
First of all I need to instantiate AntLogger in ant tasks
so AntLogger needs to be made public.
But that is not enough since I need to instantiate it also
in DataTypes (FileSet in particular).
Also resolveFile needs to be accessed from FileSet DataType.

[X] Dont bother and use jdk1.4 as minimum requirement OR write separate package
that works exactly like jdk 1.4 on earlier jdk's

Not really
FileObject.delete() calls FileObject.delete(Selectors.SELECT_SELF)
So all the juice is in delete(FileSelector)
There we find section
>>> SNIP
// If the file is a folder, make sure all its children have been deleted
if (file.type == FileType.FOLDER && file.getChildren().length != 0)
{
