[slime-devel] Slime hangs on startup
Newly-installed Debian unstable Linux zotz 2.6.11-1-686 #1 Mon Jun 20 22:00:38 MDT 2005 i686 GNU/Linux SBCL 0.9.1.41, SLIME from CVS Does not switch from *inferior-lisp* frame to listener in either mule or nomule XEmacs; hangs with e.g. ;; Swank started at port: 1033. In the repl window, there is a message like debugger invoked on a UNDEFINED-FUNCTION in thread 5710: The function SWANK:SWANK-DEBUGGER-HOOK is undefined. and then a prompt, but entering anything at the prompt results in no action but a message in the modeline ; pipelined request... (swank:listener-eval " ") C-h l shows Loading regexp-opt...done Loading regexp-opt... Loading cl-indent...done Loading cl-indent... Connecting to Swank on port 1035.. Polling "/tmp/liam/slime.5640"..

I've had no problems with slime on other computers, even other computers on this network. Any ideas? Hints on how to debug? Thanks. Liam

I'm not utterly convinced this is a combination currently supported if the SBCL is built with threads. Certainly the symptoms you describe could be a mismatch of expectations. Christophe
I probalbly posted this before. Does anyone have encountered problems with that combination I'm using SBCL 0.9.2.51 and the CVS-Slime. the message I got is: implicitly creating new generic function STREAM-READ-CHAR-WILL-HANG-P ;; loading #P"/home/frido/.slime/fasl/sbcl-0.9.2.51-linux-x86-64/swank.fasl" WARNING: These Swank interfaces are unimplemented: (ACTIVATE-STEPPING CALLS-WHO DISASSEMBLE-FRAME INSPECT-FOR-EMACS RESTART-FRAME SLDB-BREAK-AT-START SLDB-BREAK-ON-RETURN WHO-BINDS WHO-CALLS WHO-MACROEXPANDS WHO-REFERENCES WHO-SETS WHO-SPECIALIZES) T * ;; Swank started at port: 33038. 33038 * Process inferior-lisp hangup Is there anything I can do to get a multithreaded SBCL running with Slime?

Is there anything I can do to get a multithreaded SBCL running with Slime?

I'm sorry for replying so late. This problem was discussed on sbcl-devel some time ago. AFAICT it is present since the sbcl pthread merge (0.9.1.59) under some kernels. The immediate cause is emacs sending a SIGHUP to sbcl that does not have a handler and promptly exits which is the right behaviour. My tests showed that even if :sigio or :fd-handler is used, the first thread exit makes emacs send sighup. A possible workaround is: (setq inferior-lisp-program "nohup sbcl") or writing a little wrapper script around sbcl if you want *inferior-lisp* keep its sanity: #!/bin/sh sbcl But probably it is a kernel problem after all: for me the problem went away after a 2.6.8 -> 2.6.11 upgrade.
