bug#6685: 23.2; Discards control characters during boot.

[Trent W. Buck]

I start emacs with a wrapper script which boils down to

    ALTERNATIVE_EDITOR="" emacsclient -c -t

In the past (23.1 or so), I could start emacs that way, and while the
daemon was loading in the background, I could type

    M-x irc C-m M-x gnus C-m

and when the daemon finished loading, the IRC and GNUS functions would
run.  Now, what happens is that I get

    xircxgnus

appended to *scratch*.  It seems pretty clear to me that Emacs has
started discarding control characters (^[ and ^M in my case).

If this change was an attempt to fix a bug, it has actually fixed a
feature (for me), since I now have to wait a couple of seconds for the
frame to render before I can reliably start issuing commands.

Note: I haven't reproduce this with --quick, because that starts too
fast and in any case I don't know how to make emacsclient -A='' pass -Q
to it's internal emacs --daemon invocation.

As far as I can tell, this old bug was fixed by the introduction of
xterm-extra-capabilities (set it to nil to avoid discarding
pre-terminal-initialization input).

That appears to be defined in lisp/term/xterm.el, so it will only be
loaded when TERM=xterm.  Currently this is not the case for me;
TERM=screen and outside that TERM=linux (I am on the kernel fbcon).
I believe that was also the case when I reported the original bug.

(I have not actually tested this yet, as that variable is not
available in the 23.3 I have to hand just now.)

[Andrew Hyatt]

I was trying to reproduce this in Emacs 25, but emacsclient will not
start up a new emacs instance with emacsclient. According to the
documentation I have on emacsclient on using the alternative editor
flag:

If the value of EDITOR is the empty string, run "emacs --daemon" to
start Emacs in daemon mode, and try to connect to it.

So I can't reproduce this issue anymore.  Let me know if I'm missing
something, please.

Sorry, I don't understand what you are saying.  Starting the daemon
with ALTERNATIVE_EDITOR="" was part of the recipe; you seem to say it
no longer works, although the documentation still says it should?  It
certainly works for me, if I understood correctly what you described.

It doesn't work for me for some reason, and the documentation seems to
imply that it shouldn't work.  If using ALTERNATIVE_EDITOR="" started emacs
in daemon mode, why would the documentation tell the user to run the "emacs
--daemon" manually?  Instead, what I get when I don't have an emacs in
daemon mode, is just emacsclient telling me there's no emacs daemon running.

Judging by your response, I feel I must be misunderstanding something, but
I don't know what.

What happens if you try this command on your system?  That is, if you
type

  ALTERNATE_EDITOR='' emacsclient -t -c

What I see on a typical GNU/Linux system is this:

  /home/e/eliz/emacs-current/lib-src/emacsclient: can't find socket; have you started the server?
  To start the server in Emacs, type "M-x server-start".

  Warning: due to a long standing Gtk+ bug
  http://bugzilla.gnome.org/show_bug.cgi?id=85715
  Emacs might crash when run in daemon mode and the X11 connection is unexpectedly lost.
  Using an Emacs configured with --with-x-toolkit=lucid does not have this problem.
  ("emacs")
  Loading 00debian-vars...
  [More packages loading from the site-init file...]
  Starting Emacs daemon.
  Restarting server
  Emacs daemon should have started, trying to connect again

and then I see an Emacs frame (in text mode in this case, since -t was
used) open.  As you see, after warning me about no daemon running,
emacsclient starts a new daemon, then attempts to reconnect to it.

What happens if you try that?

Yes, you are correct - I must have had a typo.  When I tried it again
today, it works as you describe, and I was able to reproduce the
original bug.  Thanks for the help.

I still think the manual seems to say this shouldn't be expected to
work, which is odd.

The original bug is probably due to the initial queries we make to see
if xterm supports some advanced features.  Can you see if this is
indeed the culprit?

Not sure which part you think says that, the documentation sounds
correct to me.

I tried adding

    (setq xterm-extra-capabilities nil)

to my ~/.emacs and as at

    GNU Emacs 24.4.1 (x86_64-pc-linux-gnu) of 2014-10-26 on trouble,
    modified by Debian

...I still saw that M-x turned into just x if I typed it while Emacs
was starting (using ALTERNATE_EDITOR= emacsclient -c -t).

I tried using *just* that line as my .emacs,
but emacs started too fast for me to type the M-x. :-)

I don't have a 25.x handy to test with - since 24.4 has
xterm-extra-capabilities I hope it's new enough to be a useful test.

It definitely doesn't happen with just "emacs" instead of
"ALTERNATE_EDITOR= emacsclient -c -t".
