EMMS Last.fm issues

[Dmitry Dzhus]

Greetings!

Recently I was looking at EMMS' Last.fm functionality as I wish to
listen to lastfm:// streams using my Emacs.

I've got EMMS 3.0 and GNU Emacs 23.0.60.1, built on 2008-01-31.

An attempt to launch lastfm:// playback using `M-x emms-lastfm-radio RET
lastfm://globaltags/jazz` fails, producing the following in `*Messages*`
buffer:

    Contacting host: ws.audioscrobbler.com:80
    EMMS: Handshaking for Last.fm playback successful
    Contacting host: ws.audioscrobbler.com:80 [3 times]
    Tramp: Opening connection for http using scp...
    Tramp: Waiting 60s for local shell to come up...
    EMMS: All track information loaded.
    Tramp: Sending command `ssh http   -e none && exit || exit'
    Tramp: Waiting for prompts from remote shell
    File error: Permission denied
    error in process sentinel: tramp-error: Permission denied
    error in process sentinel: Permission denied

Which is really funny as it seems that some HTTP functions magically
call TRAMP functionality which is definetely irrelevant here.

How can it be fixed?

Hm, I'm using emms from darcs and the current emacs CVS trunk, and here
tramp won't be triggered.  I'd suggest you first try to update your
emacs and emms copy and see if the problem vanishes.

Bye,

I'm using a fairly recent Emacs CVS with EMMS (3.0):

GNU Emacs 23.0.60.1 (x86_64-pc-linux-gnu, GTK+ Version 2.12.9) of
2008-05-10 on elegiac, modified by Debian

and I see the same error messages that the OP reported, albeit with a
weird deactivation of Last.fm plugin right after the call to
`emms-lastfm-radio':

---<---------------cut here---------------start-------------->---
EMMS Last.fm plugin deactivated
Contacting host: ws.audioscrobbler.com:80
Tramp: Opening connection for http using scp...
Tramp: Waiting 60s for local shell to come up...
Tramp: Sending command `ssh http   -e none && exit || exit'
Tramp: Waiting for prompts from remote shell
File error: Permission denied
error in process sentinel: tramp-error: Permission denied
error in process sentinel: Permission denied
EMMS: All track information loaded.
---<---------------cut here---------------end---------------->---

Any suggestions appreciated. Thanks.

The released EMMS 3.0 or the current darcs trunk, which identifies as
3.0, too?

Again, I cannot reproduce that.

If you don't use a current darcs checkout of EMMS, please try that
first.  After 3.0 was released, I've rewritten some parts of emms-lastfm
cause last.fm changed their API.

You don't need to install darcs if that's a problem for you.  Lucas
makes daily snapshots you can download from [1].

If you can reproduce this error even with a current EMMS version, please
send a clear recipe starting with emacs -Q and manually loading EMMS.

Bye,
Tassilo

I just updated the scripts, they now produce a snapshot of Michael's
repo, instead of forcer's.
