Git VC commands on remote file via Tramp

Git VC commands on remote file via Tramp

[André Cruz]

Hello all.

I'm having some problems using the VC commands on a remote file which  
has a Git backend. On local files I can use Git as a vc backend with  
no problems but on remote files I get:

Debugger entered--Lisp error: (error "No fileset is available here.")
   signal(error ("No fileset is available here."))
   error("No fileset is available here.")
   vc-deduce-fileset()
   vc-print-log()
   call-interactively(vc-print-log nil nil)

I'm using the latest Emacs from CVS and the latest tramp version. Is  
the problem on Emacs, vc-git.el or tramp?

Thanks for the help,
André Cruz

André did send me already the Tramp logs. I would say Tramp behaves as
expected; I didn't see a problem there.

I don't use git myself, so it would be a little bit harder for me to
test. But scanning vc-git.el, I've seen it applies `call-process'. This
cannot work on remote hosts. I guess it must be replaced by
`process-file', plus adapting the file names used as arguments, because
likely they will be in Tramp syntax.

I would be willing to do the tests, but this might take a couple of
days, because first I must teach myself git first. If somebody is faster
than me, please run.

Btw, `call-process' or `start-process' are used also in vc.el,
vc-arch.el, vc-hg.el and vc-bzr.el. Likely this shall be reviewed, too.

Shall be fixed now. I did need to patch both vc-git.el and tramp.el.

Are you sure? I just did a checkout of the latest emacs cvs which has  
your changes to vc-git.el and tramp.el and I get the same error:

Debugger entered--Lisp error: (error "No fileset is available here.")
   signal(error ("No fileset is available here."))
   error("No fileset is available here.")
   vc-deduce-fileset()
   vc-print-log()
   call-interactively(vc-print-log nil nil)

Here is the log.

Also... Will I be able to backport these changes to 22.1? I work on an  
OSX machine and there is no Carbon support on the latest 23.0

Thanks for the help,

Have you applied "make bootstrap" after syncing with CVS? I don't see
the git calls in the trace which shall happen now.

I don't believe so. vc-git.el is not there, and Tramp 2.0 (which is
the version in Emacs 22) is seriously different to Tramp 2.1.

You're right. Didn't know I had to do that.
It works. :)

That's a shame...
