2002-09-20  Kai Gro�ohann  <Kai.Grossjohann@CS.Uni-Dortmund.DE>

	property.

	tramp-encoding-command, tramp-decoding-command,
	tramp-encoding-function and tramp-decoding-function are not
	parameters anymore.
	(tramp-uuencode-region): Autoload it.

2002-09-13  Kai Gro�ohann  <Kai.Grossjohann@CS.Uni-Dortmund.DE>

	Version 2.0.19 released.

2002-09-13  Kai Gro�ohann  <Kai.Grossjohann@CS.Uni-Dortmund.DE>

	* net/tramp.el (tramp-handle-write-region): Wrong parens.

2002-09-13  Kai Gro�ohann  <Kai.Grossjohann@CS.Uni-Dortmund.DE>

	Version 2.0.18 released.

	* net/tramp.el (tramp-perl-decode): Perl changes to accomodate
	older versions of Perl.  Now tested with 5.004.  Suggestion from
	Michael Albinus.

2002-09-12  Kai Gro�ohann  <Kai.Grossjohann@CS.Uni-Dortmund.DE>

	* net/tramp.el (tramp-find-inline-encoding): Call
	tramp-call-local-coding-command with nil for INPUT and OUTPUT.
	(tramp-call-local-coding-command): OUTPUT equals nil means to
	discard the output.  INPUT equals nil means /dev/null.

2002-09-12  Kai Gro�ohann  <Kai.Grossjohann@CS.Uni-Dortmund.DE>

	* net/tramp.el (tramp-encoding-shell): Default to environment
	variable COMSPEC on Windows.
	(tramp-handle-write-region): More debugging output.
	(tramp-find-inline-encoding): Ditto.

2002-09-11  Michael Albinus  <Michael.Albinus@alcatel.de>

	* net/tramp.el (tramp-completion-handle-file-name-all-completions):
	Define `result1'.
	(tramp-parse-hosts-group): Discard IPv6 entries.

2002-09-11  Kai Gro�ohann  <grossjoh@ls6.informatik.uni-dortmund.de>

	* net/tramp.el (tramp-post-connection): Only send Perl
	mime-encode/decode implementations when using inline method.
	(tramp-handle-file-local-copy)
	(tramp-handle-write-region, tramp-post-connection)
	(tramp-coding-commands, tramp-find-inline-encoding): For the
	inline encodings, distinguish between local and remote commands,
	instead of between commands and functions.  (The local commands
	can be functions, too.)  If the local host is a Windows machine,
	we can't expect the same commands to work there as on the remote
	host.
	(tramp-call-local-coding-command): New function for calling local
	encoding and decoding commands.
	(tramp-set-remote-encoding, tramp-get-remote-encoding)
	(tramp-set-remote-decoding, tramp-get-remote-decoding)
	(tramp-set-local-encoding, tramp-get-local-encoding)
	(tramp-set-local-decoding, tramp-get-local-decoding): New
	functions.
	(tramp-get-encoding-command, tramp-set-encoding-command)
	(tramp-get-decoding-command, tramp-set-decoding-command)

	functions, removed.

2002-09-10  Kai Gro�ohann  <Kai.Grossjohann@CS.Uni-Dortmund.DE>

	* net/tramp.el (tramp-open-connection-setup-interactive-shell):
	Change command to invoke /bin/sh slightly to make it compatible
	with the `rc' shell.  Suggested by Daniel Pittman.

2002-09-10  Michael Albinus  <Michael.Albinus@alcatel.de>

	* net/tramp.el (tramp-handle-write-region): Added missing
	`)'. Hope it's the right place.

2002-09-09  Kai Gro�ohann  <Kai.Grossjohann@CS.Uni-Dortmund.DE>

	* net/tramp.el (tramp-open-connection-setup-interactive-shell): Do
	"exec env PS1='$ ' /bin/sh" instead of just "exec /bin/sh" in
	order to get a sane shell prompt.  If people have ${CWD}, say, in
	their shell prompt, then the default login shell might display
	something harmless, but the /bin/sh will display a dollar sign
	which confused the subsequent prompt recognition.
	(tramp-multi-action-password): More debugging output.
	(tramp-encoding-shell): Renamed from tramp-sh-program.  More
	documentation.  Default to cmd.exe on Windows NT.
	(tramp-encoding-command-switch): New variable.  Use instead of
	hard-wired "-c" which is only good for /bin/sh.
	(tramp-encoding-reads-stdin): New variable.  If t, commands are
	called like "/bin/sh -c COMMAND <INPUT", if nil, they are called
	like "/bin/sh -c COMMAND INPUT", ie the input file is the last
	argument.
	(tramp-multi-sh-program): Always default to tramp-encoding-shell.
	(tramp-handle-file-local-copy, tramp-handle-write-region): Respect
	tramp-encoding-shell and friends.
	(tramp-find-inline-encoding): Use new-style calls for checking if
	the local commands work.

2002-09-07  Michael Albinus  <Michael.Albinus@alcatel.de>

	* net/tramp.el (tramp-methods): Remove `tramp-completion-function'
	entries. They are handled now by
	`tramp-completion-function-alist'.
	(tramp-completion-function): Defvar removed. I've never used
	it. Hmm.
	(tramp-get-completion-function)
	(tramp-get-completion-rsh, tramp-get-completion-ssh)
	(tramp-get-completion-telnet, tramp-get-completion-su): Functions
	removed as well. Not necessary any longer due to extended
	customization means.
	(tramp-completion-function-alist): New defcustom. Holds all
	FUNCTION FILE pairs used for user and host name completion
	relevant for METHOD.
	(tramp-completion-function-alist-rsh)
	(tramp-completion-function-alist-ssh)
	(tramp-completion-function-alist-telnet)
	(tramp-completion-function-alist-su): Defconst for initializing
	`tramp-completion-function-alist'. Unfortunately, mainly UNIX-like
	values are known for me until now. Needs to be completed for at
	least VMS++ like operating systems.
	(tramp-set-completion-function)
	(tramp-get-completion-function): New functions for configuration
	of `tramp-completion-function-alist'. The old definition of
	`tramp-get-completion-function' has been discarded.
	(tramp-completion-handle-file-name-all-completions): Change
	function call for user/host completion according to definition in
	`tramp-completion-function-alist'.
	(tramp-parse-passwd): Added exception handling for "root", because
	`tramp-get-completion-su' (the previous place for this stuff)
	doesn't exist any longer.

2002-09-07  Kai Gro�ohann  <Kai.Grossjohann@CS.Uni-Dortmund.DE>

	* net/tramp.el (tramp-enter-password): Use
	`tramp-password-end-of-line' to terminate the line.
	(tramp-bug): Include new variable `tramp-password-end-of-line'.
	(tramp-password-end-of-line): New variable.  People who use plink
	under Windows might have to issue "\r\n" after the password, but
	they need to send just "\n" after the other commands.  So this
	variable was introduced to complement `tramp-rsh-end-of-line'.
	(tramp-wait-for-output, tramp-post-connection): Allow "\r" at end
	of line of the output delimiter.

2002-09-06  Kai Gro�ohann  <Kai.Grossjohann@CS.Uni-Dortmund.DE>

	* net/tramp.el (tramp-handle-file-local-copy, tramp-find-shell)
	(tramp-open-connection-setup-interactive-shell): Add some comments
	about Douglas Grey Stephen's suggestions to make Tramp work better
	with plink under Windows.  I'm not sure what to think of them, but
	now I have a guinea pig to try it out on.  Said guinea pig is
	having other problems, though...  Also remove some commented-out
	code.

2002-09-06  Michael Albinus  <Michael.Albinus@alcatel.de>

	* net/tramp.el (tramp-get-completion-methods): Algorithm slightly
	tuned.
	(tramp-get-completion-user-host): Accept user names as they are if
	typed until "@".
	(tramp-completion-mode): Replace `last-input-char' by modern
	`last-input-event'. Check for `event-modifiers'.

2002-09-06  Kai Gro�ohann  <Kai.Grossjohann@CS.Uni-Dortmund.DE>

	* net/tramp.el (file-expand-wildcards): Corrected check to see if
	advising is necessary.

2002-09-05  Michael Albinus  <Michael.Albinus@alcatel.de>

	* net/tramp.el (tramp-postfix-single-method-format)
	(tramp-postfix-multi-method-format)
	(tramp-postfix-multi-hop-format)
	(tramp-postfix-user-format): New format strings.

	(tramp-postfix-multi-method-regexp)
	(tramp-postfix-multi-hop-regexp)
	(tramp-postfix-user-regexp)
	(tramp-make-multi-tramp-file-format)
	(tramp-make-tramp-file-name): Apply them.
	(tramp-completion-handle-file-name-all-completions): Fix for
	invoking ange-ftp in case of "/ftp:xxx" file names.

	(tramp-parse-rhosts-group)
	(tramp-parse-shosts-group)
	(tramp-parse-hosts-group)
	(tramp-parse-passwd-group): Apply these expressions.
	(tramp-file-name-structure-unified)
	(tramp-file-name-structure-separate)
	(tramp-make-tramp-file-format-unified)
	(tramp-make-tramp-file-format-separate)
	(tramp-make-tramp-file-format)

	names. Generate tramp file format on-the-fly depending on
	parameters. Apply atomar format strings resp expressions.
	(tramp-get-completion-methods)
	(tramp-get-completion-user-host): Apply
	`tramp-make-tramp-file-name'.
	(tramp-parse-hosts-group): Take all host names and IP addresses
	into account.
	(tramp-bug): Remove `tramp-make-tramp-file-format'.
