Apologies folks for the cross-threading, this is related to the issue many have experienced running SLIME on a threaded SBCL under Darwin x86.

(Mysterious > messages to terminal is not usually a good sign...) Support for a timeout value appears to be there for futexes, and I think all of the lutex platforms support pthread_cond_timedwait. It should be fairly simple to support a :TIMEOUT optional parameter in CONDITION-WAIT. To address the issue, are there any major concerns with the following approach?

[slime-devel] Threading warnings on SBCL 1.0.19 Darwin x86
by Scott Bell 29 Aug '08

29 Aug '08

Hi folks, I'm receiving the following warning messages in the *slime-repl sbcl* buffer after updating to the latest CVS yesterday: WARNING: Releasing #S(SB-THREAD:MUTEX :NAME NIL :%OWNER NIL :LUTEX #<unknown pointer object, widetag=#x5E {120B1017}>), owned by another thread: NIL This message occurs many times a second and quickly populates the buffer with thousands of lines. I was able to reproduce this issue with SBCL 1.0.18 and 1.0.19 on Darwin x86 (Mac OS X 10.5.4). Regards, - Scott Bell

[slime-devel] Fancy Inspector broken?
by Ariel Badichi 28 Aug '08

Hello, It seems that the fancy inspector is broken in the latest SLIME. When I try to inspect, say, the symbol FOO, I get: error in process filter: let*: Wrong type argument: listp, :action error in process filter: Wrong type argument: listp, :action I use SBCL 1.0.19.25. Ariel

[slime-devel] bit-vectors
by Stas Boukarev 27 Aug '08

27 Aug '08

When I place cursor after special variable containing bit-vector, slime tries to display it whole in minibuffer, which is slow and if size of vector is very large it may crash slime: (defparameter *foo* (make-array 20000000 :element-type 'bit)) *FOO* -- With Best Regards, Stas.

[slime-devel] CMUCL Flow control
by Madhu 27 Aug '08

27 Aug '08

Helu You may recall unanswered issues I've raised in the past where incorrect SLIME code crashes CMUCL and buries it in an ldb prompt. I suspect this has not been addressed in the recent overhaul of the communication code and believe bug can be illustrated [in current CVS with the following steps] In the repl, type ,---- | CL-USER> (inspect (make-instance 'standard-object)) `---- This responds with an assertion failed, in the [possibly buggy] repl code refuses to accept input. Then prints: ,---- | #<STANDARD-OBJECT {5894AE15}> is an instance of #<STANDARD-CLASS STANDARD-OBJECT | {2831D1C5}>. | > `---- At the > prompt enter `q' RET At the REPL hit C-c 4 times. Slime loses the connection and CMUCL is dead in ldb> Is this reproducible by others? I believe the fix I had suggested earlier would still protect the CMUCL from dying. -- Madhu

[slime-devel] alternative SLIME-DEBUGGER-HOOK
by Madhu 27 Aug '08

27 Aug '08

The new SLIME debugger always reports a "Use Default Debugger" restart as restart 0. This is confusing to my muscle memory which has been trained to 0 for the first restart expected from the lisp program being evaluated. Also, almost always, I never wish to invoke the native debugger from [or vice versa for which I set set swank:*global-debugger* to nil when my lisp is running outside Emacs or has its own IDE.] If nobody is using this option, or it was introduced for debugging slime, it may be better to turn it off. An `invoke native debugger' restart may be useful in the case where invoke-slime-debugger signals an error. That code is more complex. The following patch introducing a global, is ugly. -- Madhu diff --git a/swank.lisp b/swank.lisp index 058663c..450ad6b 100644 --- a/swank.lisp +++ b/swank.lisp @@ -2065,14 +2065,21 @@ after Emacs causes a restart to be invoked."

[slime-devel] SLIME can not compute backtrace in ECL
by Anton Vodonosov 27 Aug '08

27 Aug '08

Hello. Test case: start slime with ECL and compute in the REPL bufer: (/ 1 0) Instead of showing SLDB buffer emacs reports: error in process filter: Wrong number of arguments: nil, 0 This happens because stack frames list in the :debug message received from swank is empty. Corresponding changes were committed at August 12, 2008. I do not know what the proper fix will be, but at least reverting EVAL-FOR-EMACS as in the diff attached makes the SLDB buffer with stack trace appearing. Best regards, -Anton
