Modified remote file name syntax

Modified remote file name syntax

[Michael Albinus]

Hi,

today I've committed a patch, which changes the remote file name syntax
in Emacs. The "method" part, optional until now, becomes
mandatory. Valid remote file names are now

/method:host:/path/to/file
/method:user@host:/path/to/file

A new method, "-", has been added which is a marker for the default
method as known so far.

The reason is, that all the time there have been problems in Tramp due
to syntactic ambiguities. A remote file name "/foo:" has not been
distinct; "foo" could be either a method or a host name. This has
resulted in permanent problems during file name completion.

The changes will be visible with the next releases of Tramp 2.3.2 and
Emacs 26.1.

Best regards, Michael.

Hi Michael,

after your commit ed33337c3e0d0b1a8b140e23168421ea43d79324
i cannot launch emacs with a symbolic link.

To reproduce:

;; Make a link to the emacs executable in a dir inside your PATH.
;; For instance, i have the link ~/bin/emacs
(if (member (file-name-as-directory (expand-file-name "~/bin")) 
(parse-colon-path (getenv "PATH")))
     (message "OK, '~/bin' is in PATH")
   (error "'~/bin' not in PATH"))

;; Launch Emacs using this link.
M-& emacs -Q ; It doesn't work.

;; Note that the following is OK:
M-& ~/soft/emacs-master/src/emacs -Q

I've followed your recipe exactly. The emacs is the recent one:

--8<---------------cut here---------------start------------->8---
C-h C-a
GNU Emacs 26.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.20.9)
 of 2017-03-14

M-& which emacs
/home/albinmic/bin/emacs

M-& ls -l `which emacs`
lrwxrwxrwx 1 albinmic albinmic 34 Mär 14 09:36 /home/albinmic/bin/emacs -> /home/albinmic/src/emacs/src/emacs

M-& ls -l /home/albinmic/src/emacs/src/emacs
-rwxrwxr-x 3 albinmic albinmic 56720584 Mär 14 08:43 /home/albinmic/src/emacs/src/emacs

M-& emacs -Q
--8<---------------cut here---------------end--------------->8---

It comes up. So I don't know why it doesn't work for you :-(

Best regards, Micahel.

It might be because i don't use a stable release of Debian.  I update
it mostly every day.

Thank you.  Your receipt looks identical:

M-& which emacs
/home/calancha/bin/emacs

M-& ls -l `which emacs`
lrwxrwxrwx 1 calancha calancha 42 Mar 14 11:11 /home/calancha/bin/emacs -> /home/calancha/soft/emacs-master/src/emacs
M-& emacs -Q

I see following error in *Async Shell Command*:
(maybe someone suspect something)

Warning: arch-dependent data dir '/usr/local/libexec/emacs/26.0.50/x86_64-pc-linux-gnu/': No such file or directory

Warning: Could not find simple.el or simple.elc
Gtk-Message: Failed to load module "pk-gtk-module"
Gtk-Message: Failed to load module "pk-gtk-module"

The new Emacs instance shows the *scratch* buffer and the error:
Cannot open load file: No such file or directory, mule-util

Following also works fine.
M-& which ~/bin/emacs -Q

If i checkout the commit right before yours, that is
f591765e2b6b9ec3fa3ff647c77a10c984f78133
i don't reproduce the issue.

Did you run "make bootstrap"? My commit changes autoloads; while working
on the patch I was urged several time to run a bootstrap in order to
bring Emacs in a proper state.

Best regards, Michael.

I have no further idea. However, messages like "Warning: Lisp directory
'/usr/local/share/emacs/26.0.50/lisp': No such file or directory" look
very suspicious.

If you run this constellation prior my patch (everything works fine),
could you check in the running Emacs where simple.el and other files are
located according to M-x locate-library ?

It seems also to me, that /usr/local/share/emacs/26.0.50/lisp should not
be in game. I suppose, that you haven't run "make install" yet;
everything at /usr/local/share might not contain the recent changes.

Best regards, Michael.

I have one instance of Emacs started with -Q
(version: f591765e2b6b9ec3fa3ff647c77a10c984f78133)

M-x locate-library RET simple RET

That's right, i didn't run "make install".  Everything is under:
~/soft/emacs-master

drwxrwsr-x 2 root staff 4096 May 30  2016 site-lisp
;; There is no 26.1 as expected.

M-: (dired "~/soft/emacs-master") RET
M-& git checkout tmp-ed33337c3e0d0b1a8b140e23168421ea43d79324 RET

Of course. The error speaks about 26.0.50.

Hi Michael,
after your last commit (5a64d78854998c2ed6d9b8de1b593d8462b8fa39)
everything is OK.  No more issue.
Thank you very much.

Oops. My commits from today are unrelated to your problem. I believe.

Yes, PLEASE. I hope the problem doesn't reoccur, after closing the file.
