Subject: [Aquamacs-bugs] problem with comint
Enter your bug report here.
I had been using Aquamacs with Matlab, using the Matlab EmacsLink
interface,
which allows debugging of Matlab scripts in Emacs. Up until
yesterday, the
interface was working fine. Today, it crashes Aquamacs. I've
tracked down
the problem to this line (which seems to be unrelated to Matlab):
(make-comint "MATLAB EEI" (cons (system-name) 5600))
which (according to the docs for make-comint) is supposed to open a
TCP
connection to the local computer on port 5600. This displays "loading
comint..." in the minibuffer, then the mouse cursor turns into the
spinning
wheel and Aquamacs stops responding. I have to kill it using "Force
Quit".
I'm at a loss as to how to debug this further. It's probably
something
related to my system, but I don't know the details of how Aquamacs
handles
TCP connections to figure anything more out.
Any thoughts?
Cheers,
Eric Tytell

Subject: Re: [Aquamacs-bugs] problem with comint
Hi David -
In the documentation on my system for make-comint, it states that
it can
take two types of "program" arguments: either an executable program,
or a
cons pair, like the one I passed, with the form (HOST . SERVICE),
which will
open a TCP connection via open-network-stream.
After a little more fiddling yesterday, I found that it doesn't crash
Aquamacs -- after about 15min, the lisp debugger kicks in and
returns an
error. Here's the full stack trace:
Debugger entered--Lisp error: (file-error "make client process failed"
"connection refused" :name "MATLAB EEI" :buffer #<buffer *MATLAB
EEI*> :host
"hedgehog.local" :service 5600)
make-network-process(:name "MATLAB EEI" :buffer #<buffer *MATLAB
EEI*>
:host "hedgehog.local" :service 5600)
open-network-stream("MATLAB EEI" #<buffer *MATLAB EEI*>
"hedgehog.local"
5600)
comint-exec(#<buffer *MATLAB EEI*> "MATLAB EEI" ("hedgehog.local" .
5600)
nil nil)
make-comint-in-buffer("MATLAB EEI" nil ("hedgehog.local" . 5600) nil)
apply(make-comint-in-buffer "MATLAB EEI" nil ("hedgehog.local" .
5600) nil
nil)
make-comint("MATLAB EEI" ("hedgehog.local" . 5600))
eval((make-comint "MATLAB EEI" (cons (system-name) 5600)))
In the end, I think it's not a problem with Aquamacs, specifically --
Emacs.app has precisely the same issue. It's most likely something
about my
system.
But any help you can provide in debugging this issue would be
excellent.
Cheers,
Eric
