grep -nH -e cpuprc *.c

Terminal type?
The grep seems to hang at this point. It used to work. Tried
searching for terminal type without success

You might try to set `debug-on-quit' and when Emacs hangs, press C-g and
send the backtrace.
Anyway, the problem looks very much like the issue discussed here:
http://article.gmane.org/gmane.emacs.devel/126393
Unfortunately, the developers seem to be ignoring it.

What kind of shell are you running? Are you doing any stty or other terminal
related things in your dot-files for that shell? Are there perhaps some
global files that the shell reads on startup, for example /etc/bashrc?
How does it look if you put
TERM=vt100 grep -nH -e cp cpuprc *.c
as the grep command?

The hang may be caused by that problem, but the cause is the terminal type
being set is not recognized. Fixing the hang will probably not make grep work
in this case.

I think the correct term is "not talking about the work being done in public" :-)

I run tcsh as I have done for ~25yrs. I have never got on with
bash/sh
No terminal stuff in .login or .cshrc, only environment variables and
aliases
If it matters this is OpenSuSE 11.2
Emacs is started from a fvwm menu, not a terminal

The real problem is that in lisp/grep.el there is
(defun grep-process-setup ()
...
;; Any TERM except "dumb" allows GNU grep to use `--color=auto'
(setenv "TERM" "emacs-grep")
(setenv "GREP_OPTIONS"
(concat (getenv "GREP_OPTIONS")
" --color=" (if (eq grep-highlight-matches 'always)
"always" "auto")))
...
but there is no terminal type emacs-grep so the process call fails to
start before it gets to call /bin/grep or set TERM=vt100
So, what is this emacs-grep terminal type and how did it change from when
it worked.

Nothing suggests anyone is working on fixing the problem. If you have a
fix, why don't you commit it? If you don't have a fix *now*, why is the
breakage not reverted for the time being? I didn't even get any reaction
on this question.
I don't expect the trunk to be perfectly usable all the time, but I fail
to see any value in leaving a known and repeatedly reported breakage in
for an extended period of time.
Anyway, thanks for at least expressing your (IMO overly) optimistic view
on the matter.

Ok, it is probably tsch. Check if you have this in /etc/csh.cshrc, I have it
on Suse 11.2:
#
# Avoid trouble with Emacs shell mode
#
if ($?EMACS) then
setenv LS_OPTIONS '-N --color=none -T 0';
path tset -I -Q
path stty cooked pass8 dec nl -echo
# if ($?tcsh) unset edit
endif
You can force Emacs to use sh or bash if you customize shell-file-name. I
don't know if Emacs should be able to handle this.

emacs-grep was introduced in late 2007:
revno: 82277
committer: Juri Linkov <juri@jurta.org>
timestamp: Fri 2007-11-23 00:32:05 +0000
message:
(grep-process-setup): Set envvar "TERM" to "emacs-grep".
Set envvar "GREP_OPTIONS" to "--color=auto" instead of "--color=always".
My guess is that Suse changed if this worked for you on an Emacs newer than
this change.

I don't have a recepie for repeating the problem turning off ICANON would
solve. It isn't a high priority for me.

The breakage must have fixed some other problem. If breakage one is better
than breakage two is a matter of opinion, depending which one you see the
most. AFAIK, I haven't seen either.

This was a result of the following thread:
http://thread.gmane.org/gmane.emacs.devel/83316
So we could either set "TERM" to "emacs" (if it helps)
or create a terminfo file that describes "emacs-grep".

"emacs" is also unknown in Suse, so it would not matter. No, this is a Suse
matter, they should not put in terminal stuff in their /etc/csh.cshrc.

I can't make much sense of Stefan's commit message. It also doesn't
mention any related bug it would be supposed to fix.

Set which TERM to emacs? What is a terminfo file? Why did this start
being a problem in the last month?

Jan said that Suse should not put in terminal stuff in their /etc/csh.cshrc.
So please try a fix that Jan posted in another message.

Just to clarify, the fix is to customize shell-file-name to /bin/sh.

I did some tests when this come up. Basically I adopted xterm:s approach with
buffering. But this makes send_process asynchronous when the subprocess isn't
reading. It may be a too big of a change.
Besides, with the current send_process implementation, it does seem to do the
right thing, so asynchronous send is perhaps not needed. As I said, I haven't
been able to trigger any problem with it, RAW or ICANON. The only problem is
if the subprocess doesn't read, Emacs hangs forever.
The code and the documentation is not in sync w.r.t. EOF either.

The code mentions the same problem to the current one (EOF showing up as ^D)
because the terminal is in raw mode. The scenario is that Emacs puts the
terminal in icanon mode and then the subprocess puts it in raw, ^D will be
seen by the subprocess because Emacs sends EOF as a means to flush output.
But AFAIK, Emacs doesn't send EOF to flush output anymore.
So I wont put in my stuff until Stefan has commented on his. I don't think
this is a pressing matter, this is the trunk after all, and people have other
things to do. It must be resolved before next release though.

This doesn't seem to be an Emacs bug?

Seems so. I have not had any problems since fiddling with the tcsh
