Hello.

I have very strange behaviour of ql:quickload that I observer only on ABCL. It happens when I run (ql:quickload :modf). Precondition: the system :modf is NOT installed into quicklisp.

java -jar abcl.jar --noinit --nosystem

Armed Bear Common Lisp 1.1.0 Java 1.6.0_26 Sun Microsystems Inc. Java HotSpot(TM) 64-Bit Server VM Low-level initialization completed in 0.945 seconds. Startup completed in 4.8 seconds. Type ":help" for a list of available commands.

CL-USER(1): (load "C:\Users\anton\quicklisp\setup.lisp") T CL-USER(2): (ql:quickload :modf) Error loading C:/Users/anton/quicklisp/dists/quicklisp/software/closer-mop-20130128-darcs/closer-mop.asd at line 43 (offset 1649) #<THREAD "interpreter" {40773F4B}>: Debugger invoked on condition of type LOAD-SYSTEM-DEFINITION-ERROR Error while trying to load definition for system closer-mop from pathname C:/Users/anton/quicklisp/dists/quicklisp/software/closer-mop-20130128 -darcs/closer-mop.asd: Unrecognized keyword argument ("closer-mop-packages" "closer-mop-shared") Restarts: 0: REINITIALIZE-SOURCE-REGISTRY-AND-RETRY Retry finding system closer-mop after reinitializing the source-registry. 1: ABORT Give up on "modf" 2: TOP-LEVEL Return to top level. [1] ASDF0(3):

As you see it is trying to load closer-mop. Why? If :modf ASDF is not available, quicklisp should not load anything other systems yet. Moreover, modf.asd has

:depends-on (:alexandria #-abcl :closer-mop :iterate)

So on ABCL it does not depend on closer-mop.

I got backtrace using this command:

[1] ASDF0(3): (with-open-file (stream "C:\Users\anton\unpacked\abcl\abcl-bin-1.1.0\backtrace.txt" :direction :output :if-exists :supersede :if-does-not-exist :create) (let ((*debug-io* stream)) (top-level::backtrace-command "10000")))

The resulting file is here: https://dl.dropbox.com/u/5708042/backtrace.txt.

@abcl dvelopers: this backtrace seem to contain not only the current invocation stack, but also previous calls, already finished. For example the (LOAD "C:\Users\anton\quicklisp\setup.lisp") at the very bottom of the file. Do I retrieve backtrace incorrectly?

Back to the ql:quickload problem. I know that if I install :modf with CCL, this problem doesn't happen anymore, and ABCL can load it.

Zach, how it works?

Best regards, - Anton
