Starting in late September, whenever I try to exit out of the debugger the repl prompt doesn't come back.
Example:
*slime-repl sbcl* CL-USER> o
*sldb sbcl/0* The variable O is unbound. [Condition of type UNBOUND-VARIABLE]
Restarts: 0: [RETRY] Retry SLIME REPL evaluation request. 1: [ABORT] Return to SLIME's top level. <-----------pick this one 2: [CLOSE-CONNECTION] Close SLIME connection 3: [ABORT] Exit debugger, returning to top level.
The repl buffer comes back with no prompt, and all further requests are pipelined.
This does not happen in clisp.
Some other info:
*slime-events* (:emacs-rex (swank:listener-eval "o\n") "COMMON-LISP-USER" :repl-thread 14) (:debug 0 1 ("The variable O is unbound." " [Condition of type UNBOUND-VARIABLE]" nil) (("RETRY" "Retry SLIME REPL evaluation request.") ("ABORT" "Return to SLIME's top level.") ("CLOSE-CONNECTION" "Close SLIME connection") ("ABORT" "Exit debugger, returning to top level.")) ((0 "(SB-INT:SIMPLE-EVAL-IN-LEXENV O #<NULL-LEXENV>)") (1 "(SWANK::EVAL-REGION "o\n")") (2 "((LAMBDA ()))") (3 "(SWANK::TRACK-PACKAGE #<CLOSURE (LAMBDA #) {25B5C3E5}>)") (4 "(SWANK::CALL-WITH-RETRY-RESTART "Retry SLIME REPL evaluation request." #<CLOSURE (LAMBDA #) {25B5C375}>)") (5 "(SWANK::CALL-WITH-BUFFER-SYNTAX NIL #<CLOSURE (LAMBDA #) {25B5C35D}>)") (6 "(SWANK::REPL-EVAL "o\n")") (7 "(SB-INT:SIMPLE-EVAL-IN-LEXENV (SWANK:LISTENER-EVAL "o\n") #<NULL-LEXENV>)") (8 "(SWANK::EVAL-FOR-EMACS (SWANK:LISTENER-EVAL "o\n") "COMMON-LISP-USER" 14)") (9 "(SWANK::PROCESS-REQUESTS NIL)") (10 "((LAMBDA ()))") (11 "((LAMBDA (SWANK-BACKEND::HOOK SWANK-BACKEND::FUN)) #<FUNCTION SWANK:SWANK-DEBUGGER-HOOK> #<CLOSURE (LAMBDA #) {241035BD}>)") (12 "(SWANK::CALL-WITH-REDIRECTED-IO #SWANK::CONNECTION {2401F269} #<CLOSURE (LAMBDA #) {241035CD}>)") (13 "(SWANK::CALL-WITH-CONNECTION #SWANK::CONNECTION {2401F269} #<CLOSURE (LAMBDA #) {241035BD}>)") (14 "(SWANK::HANDLE-REQUESTS #<SWANK::CONNECTION {2401F269}> NIL)") (15 "((LAMBDA ()))") (16 "((LAMBDA (SWANK-BACKEND::HANDLER FUNCTION)) #<FUNCTION (LAMBDA #) {23DC867D}> #<CLOSURE (LAMBDA #) {24103555}>)") (17 "(SWANK::SIMPLE-SERVE-REQUESTS #SWANK::CONNECTION {2401F269})") (18 "(SWANK::SERVE-CONNECTION #<SB-BSD-SOCKETS:INET-SOCKET descriptor -1 {23FB59F9}> NIL NIL :ISO-8859-1)") (19 "(SWANK::SETUP-SERVER 0 #<CLOSURE (LAMBDA #) {23F4527D}> NIL NIL :ISO-8859-1)")) (14)) (:debug-activate 0 1 nil) (:emacs-rex (swank:invoke-nth-restart-for-emacs 1 1) nil 0 15) (:return (:abort) 15) (:debug-return 0 1 nil)
These are the current contribs I'm using: (require 'slime-fancy) (require 'slime-asdf)
Just using straight socket for communication:
swank:*communication-style* => nil

It may help to add #-win32 before wait-for-input in swank-sbcl.lisp. If that doesn't help, enable swank:*log-events*.

I am actually experiencing the same problem. Adding #-win32 before "(defimplementation wait-for-input (streams &optional timeout)" does not seem to have any impact (then again, I'm not really sure as to what I should be expecting anyway). I've attached the output from the *log-events* and *inferior-lisp* with swank:*log-events* set to t. All I did in the REPL was the following: (error 'foo) upon successfull initiation of the debugger, I hit "q" which runs sldb-quit and the REPL does not respond at all.
Interesting is how I get three more lines at the end inside the *inferior-lisp* buffer using CLISP: dispatch-event: (:RETURN 0 (:ABORT) 3) WRITE: (:return (:abort) 3) wait-for-event: (:EMACS-REX . SWANK::_) NIL
It looks like the abort event is for some reason not being sent when using sbcl. I get the same result with #-win32 before wait-for-input and without.
I tried with sbcl 1.0.19, sbcl 1.0.23 - as well as with GNU EmacsW32 and GNU Emacs 22.2 (non W32 ver) on Windows XP. This is using cvs slime.
Would love to help solve this problem.
Kind regards, Thomas K.

It looks like the abort event is for some reason not being sent when using sbcl. I get the same result with #-win32 before wait-for-input and without.
Does READ-CHAR-NO-HANG work properly on socket streams? There is a comment in HANDLE-LISTEN (in win32.lisp)
;; FIXME-SOCKETS: Try again here with WSAEventSelect in case ;; HANDLE is a socket.
which makes it sound like that isn't implemented yet.
I suspect that WAIT-FOR-EVENT/EVENT-LOOP (in swank.lisp) blocks even though the timeout argument is t. To see if that's actually the case, you could generate some debug output in WAIT-FOR-EVENT/EVENT-LOOP. It's the easiest if you use LOG-EVENT for that.

Not sure - how could I test that? I think it should work on gray streams, but I'm not sure what slime is using.

Changed wait-for-event/event-loop into: -------------------------------- (defun wait-for-event/event-loop (pattern timeout) (assert (or (not timeout) (eq timeout t))) (log-event "wait-for-event/event-loop: ~s ~s~%" pattern timeout) (let ((r (loop (check-slime-interrupts) (let ((event (poll-for-event pattern))) (when event (return (car event)))) (log-event "pre wait-for-input~%") (let ((events-enqueued *events-enqueued*) (ready (wait-for-input (list (current-socket-io)) timeout))) (log-event "after wait-for-input~%") (cond ((and timeout (not ready)) (return (values nil t))) ((or (/= events-enqueued *events-enqueued*) (eq ready :interrupt)) ;; rescan event queue, interrupts may enqueue new events ) (t (assert (equal ready (list (current-socket-io)))) (dispatch-event (decode-message (current-socket-io))))))))) (log-event "-wait-for-event/event-loop: ~s~%" r) r)) -------------------------------- I attached the new *inferior-lisp* buffer. The last message is "pre wait-for-input", which indicates that its hanging inside wait-for-input. I also tried putting a log-event before read-char-no-hang inside wait-for-input, but that didn't seem to get logged for some reason. Seeing this I guess you're right. Is there any way to work around this issue? - it does work for earlier calls to wait-for-input after all (though those all don't have a timeout).

Does READ-CHAR-NO-HANG work properly on socket streams? There is a comment in HANDLE-LISTEN (in win32.lisp)
Not sure - how could I test that?
For example with:
(read-char-no-hang (let ((socket (make-instance 'sb-bsd-sockets:inet-socket :type :stream :protocol :tcp))) (setf (sb-bsd-sockets:sockopt-reuse-address socket) t) (sb-bsd-sockets:socket-bind socket #(0 0 0 0) 5000) (sb-bsd-sockets:socket-listen socket 5) (unwind-protect (sb-bsd-sockets:socket-make-stream (sb-bsd-sockets:socket-accept socket) :output t :input t :element-type 'character) (sb-bsd-sockets:socket-close socket))))
This creates a socket, waits for someone to connect, and calls read-char-no-hang on the new stream. Start this in SBCL and execute "telnet localhost 5000" in a shell. read-char-no-hang should return nil as soon as the telnet client connects.
If it just waits, then you can type something into the telnet window and the first char should appear on the SBCL side. In this case read-char-no-hang doesn't work properly, it works like the ordinary read-char.
I think it should work on gray streams, but I'm not sure what slime is using.
In this situation it's a fd-stream and the fd is a socket.
I suspect that WAIT-FOR-EVENT/EVENT-LOOP (in swank.lisp) blocks even though the timeout argument is t. To see if that's actually the case, you could generate some debug output in WAIT-FOR-EVENT/EVENT-LOOP. It's the easiest if you use LOG-EVENT for that.
Changed wait-for-event/event-loop into:
(defun wait-for-event/event-loop (pattern timeout) (assert (or (not timeout) (eq timeout t))) (log-event "wait-for-event/event-loop: ~s ~s~%" pattern timeout) (let ((r (loop (check-slime-interrupts) (let ((event (poll-for-event pattern))) (when event (return (car event)))) (log-event "pre wait-for-input~%") (let ((events-enqueued *events-enqueued*) (ready (wait-for-input (list (current-socket-io)) timeout))) (log-event "after wait-for-input~%") (cond ((and timeout (not ready)) (return (values nil t))) ((or (/= events-enqueued *events-enqueued*) (eq ready :interrupt)) ;; rescan event queue, interrupts may enqueue new events ) (t (assert (equal ready (list (current-socket-io)))) (dispatch-event (decode-message (current-socket-io))))))))) (log-event "-wait-for-event/event-loop: ~s~%" r) r))
I attached the new *inferior-lisp* buffer. The last message is "pre wait-for-input", which indicates that its hanging inside wait-for-input. I also tried putting a log-event before read-char-no-hang inside wait-for-input, but that didn't seem to get logged for some reason.
wait-for-input is in swank-backend.lisp and in swank-sbcl.lisp. Perhaps you added it in the wrong file. Those are also in different packages so, you probably need something like (funcall (read-from-string "swank::log-event") ...)
Seeing this I guess you're right. Is there any way to work around this issue? - it does work for earlier calls to wait-for-input after all (though those all don't have a timeout).
The best solution would be to fix HANDLE-LISTEN, but I don't know how to do that.
As a workaround you can probably replace (wait-for-event `(:sldb-return ,(1+ level)) t) ; clean event-queue in sldb-loop with: (poll-for-event `(:sldb-return ,(1+ level)))

You're right, it does not return nil as soon as someone connects. It does however return the first char as soon as I type something into the first window.

That actually solved the problem! Now given that the problem seems to be with sbcl's HANDLE-LISTEN, I guess I'll check out their mailing list.
Many thanks there, Thomas K.
