[armedbear-devel] strange interaction between ql:quickload and ABCL

[Anton Vodonosov]

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

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,
