VFS - Next

ram filesystem

2. apply http://issues.apache.org/bugzilla/show_bug.cgi?id=36047

services & svn filesystem (we have to setup an external space to provide the svn filesystem as the used library JavaSVN is LGPL)

we need a discussion about a new name instead of "services" (maybe).

The idea is to have calls like

Commit commitFile = FileObject.getService(Commit.class)
commitFile.process();


TumbnailImage thumb = FileObject.getService(TumbnailImage.class)
thumb.process();
Image bi = thumb.getImage();


ExifData exif = FileObject.getService(ExifData.class)
exif.process();
String camera = exif.getCameraModel();

You get the idea?

The current name proposals are:

3. user api

a way to avoid to put username/password into the url.

Using a callback mechanism to get this data when needed.

4. progress, pause and cancellation api

callbacks to be informed about ongoing operations (copy, move, rename, delete, copy-progress, move-progress (if between filesystems)) Ability to pause or cancel the operation.

5. browse roots

e.g. smb or local partitions (windows - c:, d:, ...)

6. caching review - allow to configure fileObjects internal state cache

This is to avoid the .close() calling to get fresh data.

Sure, this might slow down alot, but if one would like have it, it should be possible.

7. xpath

allow xpath style filesystem browsing

8. file permissions (non-native)

(with non native code only)

figure out a way to represent file permissions and a way to modify then

9. native parts (if possible through jdic)

  • filesystem notifications - to get informed about external filesystem events
  • file permissions to allow fine grained setup for local files
  • partition information (type, space, label) - some available in JDIC but also keep in mind this: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4057701

10. write support for archives

this would require it to

  1. copy the archive locally 2. apply the change 3. repack the archive 4. copy the archive back to its place

We should stay in state 2. until one sends a signal to finish with the archive.

new filesystems

  • pop, imap (useable for emails)
  • mime (for the email itself - pretty much like an archive)

Consider this url:

zip:mime:imap://user@mailserver/INBOX/folders/newMail.mime!/attachment1.zip!/zipentry.txt

Cool, isnt it?

  • generic XML
  • ant (only a variant of XML? Cant we just set a dtd or scheme using some sort of configurationOption ?)
  • java structure (by class, by source?)

non confimed

(add your wishes here)

x. filesystem xyz

blablabla

  • No labels
