Re: desktop Digest, Vol 76, Issue 13
by Hristo Petkov
Hi,
A Question:
The present linux desktop (at least mine on fc11) has NFS support in the Services menu. I doubt anyone uses this (I am not using it for sure). I don't know even what it is doing (is it supposed to compete Facebook and Google Me, or something).
Regards

Well, I think there's a bit of a chicken and egg problem. Since XATTRs
are not available on so many file systems (not even tmpfs has them) and
there is no nice way to test whether they work (except by creating an
attribute), nobody uses them. That said GLib's GIO framework (i..e the
API modern gtk programs use to access files) has complete coverage for
extended attributes, but probably not many folks actually use those
APIs. Also, the fact that they need to be enabled manually (via the
user_xattr mount option) is problematic.
Samba uses user xattrs. Then, there's a somewhat standardized scheme for
storing the MIME type of a file in an extended attribute, as an optional
implementation feature fo rthe XDG MIME info spec:
http://standards.freedesktop.org/shared-mime-info-spec/shared-mime-info-s...
However, at least Gtk/GLib/GIO do not implement that optional part. I
once wrote an Apache module that added support for that user.mime_type
xattr to Apache: http://0pointer.de/lennart/projects/mod_mime_xattr/
However, that's mostly where he story ends I think, it is indeed not
widely used. Generally I believe they are useful however, and if they
would be ubiquitiously available they'd probably be used more
often. However, for that to happen we'd also need something like a
fpathconf() check or so to figure out whether user xattrs are allowed or
not.
I'd be particularly interested in user xattrs support on the virtual
file systems such as /proc, /sys and tmpfs. Neither of those file systems
have support for this right now, but especially for /proc it could become
very handy to export additional meta information about processes on the
/proc/$PID directory.

Usefulness of extended attributes over NFS
by James Morris
I've been working on an implementation of extended attributes for NFSv3,
which would enable getxattr(2) and friends over the network.
Here's a link to the latest patchset:
http://lwn.net/Articles/392944/
and my LinuxCon slides on the topic from last year:
http://namei.org/presentations/linuxcon09_nfsv3xattrs.pdf
I've been asked by the upstream NFS maintainers about general use-cases
for this feature. We have a concrete requirement to convey security
labels over NFS, although it's not clear how much need there is for
user-managed extended attributes (e.g. user.foo)
I was wondering if anyone could offer examples or insights into whether
Linux desktop apps are making much use of extended attributes, or whether
they might if NFS support were available. (I'm aware of Beagle, which is
probably not great over NFS in any case).
Thanks for any help.

OpenOffice.org now uses gtk3
by Caolán McNamara
As of openoffice.org-3.2.1-19.16.fc14, OpenOffice.org is built against
gtk3 rather than gtk2.
It'll look like a throw-back to a different era unless gtk3-engines is
installed. So install gtk3-engines manually if you don't have it.

A tag may be put to the packages in the repository lists and only packages compatible with the computer architecture of the user to be listed in the Package Installer Roll.

Developer Experience
by William Jon McCann
Hey,
So one thing we talked about on IRC last week was the idea of driving
the design of the OS from two different and complementary angles: user
experience and developer experience.
We have a pretty strong and unfolding story for the evolution of the
user experience but I don't yet see discussion and planning for the
improvement of the developer experience. I imagine this could involve
things like OS platform and subsystem design, toolkit API and SDK
design, development tools, deployment and management, feedback, etc.
Anyone want to take part in some discussions and/or brainstorm
sessions on this? We might be able to arrange a call in number if we
want to try it live. Though, first, maybe we should try to research
and document things we like and dislike about existing systems.
Does this sound interesting to anyone?
Thanks,
Jon

help with nautilus-pastebin extension
by Ankur Sinha
hey,
I recently packaged nautilus-pastebin. I tested it successfully, so did
Rahul [1]
A few days ago, it stopped functioning. That is, a right click no longer
shows a "send to pastebin" option. I'm sure this isn't an error in the
nautilus-pastebin package since it's the same package that functioned
properly a few days back and Rahul and me tested.
How do I find out what update to what package caused this ?
regards,
Ankur

Hi,
Take a look in the Software Log Viewer and remember what you have done from the time when Nautilus wast last working and the moment when it crashed.

Try to run nautilus from terminal (you'll need a separate instance, so
run it as different user than you're logged in as) and look for any
error messages, it might help.
Cheers,
Martin

a11y stack change
by Matthias Clasen
Just a heads-up:
As part of the ongoing march towards GNOME3, I have switched the
accessibility stack to default to the dbus stack
(at-spi2-core/at-spi2-atk/pyatspi) instead of the Corba stack (at-spi).
Some initial testing shows that orca and caribou seem to work ok. One
issue that I've noticed so far is that firefox is unwilling to pop up
menus when accessibility is turned on. I am working with the
aeccessibility team upstream to resolve this and other issues that will
no doubt pop up.
If you notice problems that look like they might be related to this
change, please let me know.
