1) start emacs with "emacs -q -f server-start &"
2) export VISUAL="emacsclient -t"
2) less .bashrc
3) within less type "v" to edit file with $VISUAL
the result is that less writes a line
"!emacsclient -t +18 .bashrc" on the terminal, but other than that the
terminal is still showing the output of less. emacsclient
is not taking over the terminal, and no editing is possible.
Using "ps auxw" in another terminal, emacsclient appears in the
process list, though. The only thing I can do in the "less terminal"
is to type "C-c" to resume viewing the .bashrc file.
The problem seems to be specific to "emacsclient -t", since both
export VISUAL="emacsclient -c"
and
export VISUAL="emacs -nw"
work as expected.
The same problem occurs in both xterm and konsole.

This looks like a serious bug that needs to be addressed. Does anyone
have a clue about how to fix/debug this?

You can edebug `server-process-filter'. Doing that shows quickly the
problem: emacsclient passes the tty as: -tty /dev/tty.
/dev/tty means one thing for emacsclient and another one for emacs...
emacsclient.c computes the tty like this:
tty_name = ttyname (fileno (stdin));
changing it to:
tty_name = ttyname (fileno (stdout));
gets the right terminal and this problem seems to be fixed.

That seems to work fine for me too. I checked in the fix. Thanks.

Yes, but is this the right fix? The `tty' command prints "/dev/tty"
as well in the situation described by the original bug report. Why
doesn't Emacs DTRT with that name? Can it fail in a similar way with
the name of the device connected to stdout?
