-
-;;; Commentary:
-
-;; Access functions for FIles transferred over SHell protocol from Tramp.
-
-;; FISH is a protocol developped for the GNU Midnight Commander
-;; <https://savannah.gnu.org/projects/mc>. A client connects to a
-;; remote host via ssh (or rsh, shall be configurable), and starts
-;; there a fish server via the command "start_fish_server". All
-;; commands from the client have the form "#FISH_COMMAND\n" (always
-;; one line), followed by equivalent shell commands in case there is
-;; no fish server running.
-
-;; The fish server (or the equivalent shell commands) must return the
-;; response, which is finished by a line "### xxx <optional text>\n".
-;; "xxx" stands for 3 digits, representing a return code. Return
-;; codes "# 000" and "# 001" are reserved for fallback implementation
-;; with native shell commands; they are not used inside the server. See
-;; <http://cvs.savannah.gnu.org/viewcvs/mc/vfs/README.fish?root=mc&view=markup>
-;; for details of original specification.
-
-;; The GNU Midnight Commander implements the original fish protocol
-;; version 0.0.2. The KDE Konqueror has its own implementation, which
-;; can be found at
-;; <http://websvn.kde.org/branches/KDE/3.5/kdebase/kioslave/fish>. It
-;; implements an extended protocol version 0.0.3. Additionally, it
-;; provides a fish server implementation in Perl (which is the only
-;; implementation I've heard of). The following command reference is
-;; based on that implementation.
-
-;; All commands return either "### 2xx\n" (OK) or "### 5xx <optional text>\n"
-;; (NOK). Return codes are mentioned only if they are different from this.
-;; Spaces in any parameter must be escaped by "\ ".
-

+;; * Make it work for different encodings, and for different file name
+;; encodings, too. (Daniel Pittman)
+;; * Don't search for perl5 and perl. Instead, only search for perl and

+;; * When editing a remote CVS controlled file as a different user, VC
+;; gets confused about the file locking status. Try to find out why
+;; the workaround doesn't work.
+;; * Allow out-of-band methods as _last_ multi-hop. Open a connection
+;; until the last but one hop via `start-file-process'. Apply it
+;; also for ftp and smb.
+;; * WIBNI if we had a command "trampclient"? If I was editing in
+;; some shell with root priviledges, it would be nice if I could
+;; just call
+;; trampclient filename.c
+;; as an editor, and the _current_ shell would connect to an Emacs
+;; server and would be used in an existing non-priviledged Emacs
+;; session for doing the editing in question.
+;; That way, I need not tell Emacs my password again and be afraid
+;; that it makes it into core dumps or other ugly stuff (I had Emacs
+;; once display a just typed password in the context of a keyboard
+;; sequence prompt for a question immediately following in a shell
+;; script run within Emacs -- nasty).
+;; And if I have some ssh session running to a different computer,
+;; having the possibility of passing a local file there to a local
+;; Emacs session (in case I can arrange for a connection back) would
+;; be nice.
+;; Likely the corresponding Tramp server should not allow the
+;; equivalent of the emacsclient -eval option in order to make this
+;; reasonably unproblematic. And maybe trampclient should have some
+;; way of passing credentials, like by using an SSL socket or
+;; something. (David Kastrup)
+;; * Reconnect directly to a compliant shell without first going
+;; through the user's default shell. (Pete Forman)
+;; * How can I interrupt the remote process with a signal
+;; (interrupt-process seems not to work)? (Markus Triska)
+;; * Avoid the local shell entirely for starting remote processes. If
+;; so, I think even a signal, when delivered directly to the local
+;; SSH instance, would correctly be propagated to the remote process
+;; automatically; possibly SSH would have to be started with
+;; "-t". (Markus Triska)
+;; * It makes me wonder if tramp couldn't fall back to ssh when scp
+;; isn't on the remote host. (Mark A. Hershberger)
+;; * Use lsh instead of ssh. (Alfred M. Szmidt)
+;; * Optimize out-of-band copying, when both methods are scp-like (not
+;; rsync).
+;; * Keep a second connection open for out-of-band methods like scp or
+;; rsync.
+;; * Try telnet+curl as new method. It might be useful for busybox,
+;; without built-in uuencode/uudecode.

;; * Make ffap.el grok Tramp filenames. (Eli Tziperman)

;; again. (Greg Stark)
-;; * Remove unneeded parameters from methods.
-;; * Make it work for different encodings, and for different file name
-;; encodings, too. (Daniel Pittman)
-;; * Don't search for perl5 and perl. Instead, only search for perl and
-;; then look if it's the right version (with `perl -v').
-;; * When editing a remote CVS controlled file as a different user, VC
-;; gets confused about the file locking status. Try to find out why
-;; the workaround doesn't work.
;; * Username and hostname completion.
;; ** Try to avoid usage of `last-input-event' in `tramp-completion-mode-p'.
;; ** Unify `tramp-parse-{rhosts,shosts,sconfig,hosts,passwd,netrc}'.
;; Code is nearly identical.
-;; * Allow out-of-band methods as _last_ multi-hop. Open a connection
-;; until the last but one hop via `start-file-process'. Apply it
-;; also for ftp and smb.
-;; * WIBNI if we had a command "trampclient"? If I was editing in
-;; some shell with root priviledges, it would be nice if I could
-;; just call
-;; trampclient filename.c
-;; as an editor, and the _current_ shell would connect to an Emacs
-;; server and would be used in an existing non-priviledged Emacs
-;; session for doing the editing in question.
-;; That way, I need not tell Emacs my password again and be afraid
-;; that it makes it into core dumps or other ugly stuff (I had Emacs
-;; once display a just typed password in the context of a keyboard
-;; sequence prompt for a question immediately following in a shell
-;; script run within Emacs -- nasty).
-;; And if I have some ssh session running to a different computer,
-;; having the possibility of passing a local file there to a local
-;; Emacs session (in case I can arrange for a connection back) would
-;; be nice.
-;; Likely the corresponding Tramp server should not allow the
-;; equivalent of the emacsclient -eval option in order to make this
-;; reasonably unproblematic. And maybe trampclient should have some
-;; way of passing credentials, like by using an SSL socket or
-;; something. (David Kastrup)
-;; * Reconnect directly to a compliant shell without first going
-;; through the user's default shell. (Pete Forman)
;; * Make `tramp-default-user' obsolete.
-;; * How can I interrupt the remote process with a signal
-;; (interrupt-process seems not to work)? (Markus Triska)
-;; * Avoid the local shell entirely for starting remote processes. If
-;; so, I think even a signal, when delivered directly to the local
-;; SSH instance, would correctly be propagated to the remote process
-;; automatically; possibly SSH would have to be started with
-;; "-t". (Markus Triska)
-;; * It makes me wonder if tramp couldn't fall back to ssh when scp
-;; isn't on the remote host. (Mark A. Hershberger)
-;; * Use lsh instead of ssh. (Alfred M. Szmidt)
;; * Implement a general server-local-variable mechanism, as there are
;; probably other variables that need different values for different
;; servers too. The user could then configure a variable (such as
;; tramp-server-local-variable-alist) to define any such variables
;; that they need to, which would then be let bound as appropriate
;; in tramp functions. (Jason Rumney)
-;; * Optimize out-of-band copying, when both methods are scp-like (not
-;; rsync).
-;; * Keep a second connection open for out-of-band methods like scp or
-;; rsync.
;; * IMHO, it's a drawback that currently Tramp doesn't support
;; Unicode in Dired file names by default. Is it possible to
;; improve Tramp to set LC_ALL to "C" only for commands where Tramp
;; expects English? Or just to set LC_MESSAGES to "C" if Tramp
;; expects only English messages? (Juri Linkov)
;; * Make shadowfile.el grok Tramp filenames. (Bug#4526, Bug#4846)
-;; * Try telnet+curl as new method. It might be useful for busybox,
-;; without built-in uuencode/uudecode.
;; * Load ~/.emacs_SHELLNAME on the remote host for `shell'.
;; * I was wondering it it would be possible to use tramp even if I'm
;; actually using sshfs. But when I launch a command I would like
