Re: review of the Storage interface

[Dietmar Maurer <dietmar maurer-it com>]

Ok, please let me first explain the obvious changes (I will explain the
content_type
for storages later)

* use long long for indexing into files

files can be larger than 4GB - only to be save!

*  added more exceptions

I compared the currently define exception with the error messages from
gnome-vfs.

*   new revert method

If we support transaction, we need commit and revert! MS also supports that!

* added locking interface

as far as I know microsoft supports locking, and record locking (see Inside
ole)

* removed copy_to from stream

I simply donīt understand why we need that - maybe we need it - but what for?

*  removed eos, length and list_contents method

all of that can be done with the new get_info method, wich is more general.

I do not write any code - that are only my (formalized) thoughts ;-)

Iīm not a microsoft programmer, so I donīt know if the bock inside-ole
is correct? But all my suggested features are originated after reading
inside-ole.

Yes, you are right. But we have to put more information into the method.
At least if the name is a directory or not, and maybe the size and
content_type. Take a look at the microsoft interface - i would prefer that.
