Gravatar support

Gravatar support

[Julien Danjou]

Hi folks,

You had fun with picons, faces, etc, didn't you?
That was fun. But so 90's.

Welcome to 2010! Now we got Gravatar[1], used all around the Interweb.
It's like Face headers… but with more people.

So here's a full implementation of it for Gnus, with support for From
and To/Cc headers, inspired from picons support code.

The code has been tested, and the documentation updated.

What I would like:
- feedbacks;
- authorization to commit the code.

BE CAREFUL: by running Gnus with the following patch, you will do see
my face in mails I wrote.

You've been warned.

OK, "it depends on a 3rd party that we don't know, control, or
influence, and which has no responsibility or incentive to keep the
service going for our sake."  Sorry I was not precise.  Look up NoCeM
for a prior example of how this can be painful.

So, much like the google-* stuff for org-mode discussed in emacs-devel,
I'd be OK if this was done as a user choice with gravatar.com being one
of the backend providers, but my vote is no otherwise.

I think you've just illustrated the problem.  :-)

gnus-group-archive-directory
=> "/ftp@ftp.hpc.uh.edu:/pub/emacs/ding-list/"

And that server doesn't exist any more.  I haven't checked with the
gnus-group-charter-alist sites, but if many of them exist any more, I'd
be surprised.  That stuff should be removed, not added to.

On the other hand, the Gravatar stuff is more fun than the charter
stuff, so I don't know.  I mean, it's not a hard and fast rule: "The
shall be no external services!"  It's more...  "Is this external service
really useful?"

Why not unite picons, faces, and Gravatars into a consistent framework
using backends, so when and if gravatar.com goes away, for instance, we
can just remove that backend?  They all behave similarly, right?  It
seems like gnus-gravatar.el duplicates a lot of gnus-picon.el so that
would be a chance to reduce the amount of code, too.

Yes and nooo.

Faces (and X-Faces) are contained in the message headers.  Picon support
is based on the concept that you download the entire picon tree locally,
and look at it there.  And Gravatar is a service that you query online.

So it's like a gliding scale from something that is definitely
... readerish to do (Faces) to something questionable (Picons) to
something that's totally an external service (Gravatar).

I think it would make sense to remove the picon support.  I can't
imagine there are more than a handful of people in the world that uses
it.  Although the packages are still in Debian, so perhaps...

But I would like to try the Gravatar stuff, at least.  :-)  Perhaps just
install it, and then we can give it a whirl?

OK, but at least Faces vs. gravatars seems pretty close.  The code for
those two could be merged.

popcon says that, like, 50 submitters have it installed.  So, buy-in is pretty
low inside the Debian ecosystem.

"popcon" huh...?  Ah... http://popcon.debian.org/

Interesting.  But FWIW, I have been a debian user since 2001, with 4
debian boxes currently running.  And I had never heard about popcon

You should have if you installed a lenny or squeeze, since AFAIK the

...and, for what it is worth, despite it having a relatively low penetration
among Debian users the volumes are sufficiently high that it can be a passable
guide to what "average" desktop Debian users have.

eg: http://qa.debian.org/popcon-graph.php?packages=libc6

We could safely say that present contribution levels are somewhere on the
order of 90,000 data points or so, which suggests that approximately zero
percent of Debian users install the Debian picon packages.

I just tried installing the picon-packages. And article-headers turned

Ah, I'll try that right away - thanks!

Yes, that's much better. It didn't seem to work on the
Newsgroups-header, though, so I have set:

  (setq gnus-picon-style 'right
        gnus-treat-newsgroups-picon nil)

Now I think picon support should stay :-)

I just adjusted the display of faces like this:

  ; Align the top of the face with the top of the text, approximately:
  (setq gnus-face-properties-alist
        '((pbm . (:face gnus-x-face :ascent 25))
          (png . (:ascent 25))))

Does something similar exist for picons? My guess at
gnus-picon-face-properties-alist was too optimistic :-)

I've pulled in the picon-* packages on my Lucid Lynx UNE netbook, and
made the same adjustments you made.

And I agree they should stay.

(Though using 224MB out of my 8GB SSD, I doubt the packages will stay on
the netbook (which BTW wouldn't register on any debian statistics, even
though debian is why the packages are in Ubuntu...))

I guess you now agree with us that picon support should be kept. If so
then, IMHO, the default style should be changed to "right" (inline is
really ugly) and the newsgroups header display should be fixed.

Yes, I think it should probably default to nil in production, but let's
keep it enabled by default for a while to give people a taste of how it
works.

There seems to be an odd glitch that I'm not able to debug.  I have

(setq gnus-treat-date-lapsed 'head)
(gnus-start-date-timer)

in my .gnus.el, so the date line is updated.  The first time your
gravatar was inserted, the lapsed time line was inserted, too, next to
the gravatar in addition to where it was supposed to be.  Could there be
a missing `save-excursion' (or something) in the gravatar code?

Things like gravatar fetching should default to off, even in the git
version.  I realize you'd like to see people test it, but "private by
default" is the way the world ought to be, at all times.

I should not that I'm not accusing gravatar of being sinister.  Their
privacy policy looks good, although it doesn't clearly say "we keep no
logs of which IP addresses looked up which gravatars".  The point is
rather that each person should decide to deal with them or not, and
someone who just does 'git pull; make; make install' should not suddenly
find themselves making queries to their server.  I might even turn this
on myself for a while.

obtechnical: it would be cool if using the cache for display was
enablable separately from fetching.

I agree with this argument.  I've now switched the default of

gnus-treat-mail-gravatar
gnus-treat-from-gravatar

to nil.

Gravatar is nice, and the code looks good, but I'm not quite sure
whether adding functionality that relies on outside services is good.  I
mean, we've done this in the past now and then...  and it's mostly
turned out to not be good.

There is a serious privacy issue lurking, which lets gravatar.com
perform traffic analysis.  It is totally unreasonable to have any code
enabled by default that queries external servers based on received mail.

Also, there's a philosophical question about free software support for
proprietary services.  If there's a standard protocol and multiple
implementations, that seems fine.  But it seems really like this could
have been:

X-Face-URL: http://www.gravatar.com/avatar/205e460b479e2e5b48aec07710c08d50

if it's intended that requests be made about every email address, that
seems even more invasive.

I agree, but please don't start to be paranoid too. Furthermore, images
are cached to 30 days by default, so you're not going to request an
image on every mail you read.

This seems like a good use case for user configuration.  If I like
Gravatar and think it's nifty and want it to download pictures for people,
I think I should have to explicitly enable that.  Once I've done so,
though, I think it's fair game.  As long as it isn't the default, I'm not
too worried about the privacy concern; people can make an informed
decision, particularly if the documentation points out that enabling this
would allow Gravatar to perform traffic analysis and get information about
what e-mail you're reading.

Sorry, i'm lazy to read. Anyway Gravatar looks good. Currently i use
picon and Face/X-Face features in Gnus. There are so good to me.

So may i use Gravatar feature? By the way my Emacs version is "23.2". Is
it possible in my Emacs version? Could you please some advice or comment?

Ah.. never mind. I just did upgrade Emacs version to "24.1". Now i see
the images from Gravatar. I added 3 lines within ~/.gnus.el as below:

;; Gravatar!
(require 'gnus-gravatar)
(setq gnus-treat-from-gravatar 'head)
(setq gnus-treat-mail-gravatar nil)

When i switched DISPLAY_NAME from ASCII characters (Byung-Hee HWANG) to
non-ASCII characters (황병희), the avatar did not appear. So how can i
resove it?

Perhaps the gravatar code should grab the user name from the original
article buffer instead of the displayed one?  That should make all
en/decoding issues go away...

So, how does it work: Are gravatars shown instead of (X-)Face:s if both
exist?

No, faces are not disabled by it. You'd get both.

Ah, cool!

Sorry for the misunderstanding, I seem to have lost X-Face-support when
I switched from using XEmacs to using GNU Emacs the other night.

Hm. I wonder why.

                                 o o o

A little curiosity: When I read an article by someone why has no
gravatar (I guess), the minibuffer shows this:

  "Reading [text/html; charset=utf-8]... 24 bytes of 13 bytes (185%)"

... which seems a little odd? :-)

What's odd?
I wanted to disable the progress so `url-retrieve' would be silent, but
that's not possible.
185% is a usual bug in `url-retrieve'. :-)
text/html is because, well, it's a 404. But the 404 is cached, so it
will not be fetched until your cache TTL expires.

That is what I thought was odd - just 'cause I hadn't seen it before.

Perhaps patch url-retrieve to allow silencing it?

Hm, I don't get both.

If I set gnus-treat-display-x-face to head and look at one if my own
articles, I see the X-Face only. If I set it to nil, I get the gravatar
only. Not both.

I guess XEmacs is compiled with libcompface, while GNU Emacs needs the
uncompface command, that I have now installed.

In contrib/ of Gnus there is a elisp version compface.el which does not
need uncompface command. I have expected it to become official for long
time but there is no way to contact the author to sign the paper. Anyway
I can use it.

I see that too. The funny thing is that I did not write any code to do
that, and I expected the opposite. I'll dig into the treatment code, at
least to know why and if it's a bug.

The bug was in gnus-put-image, which put a "*" into the From header,
which meant that the Gravatar thing couldn't parse the header any more.
Fixed now.

I found it's fun. And easier to use then Face/X-Face since the site can
help me to upload and crop photos. 

Thank you for this feature.
