Say I download version 1 of the FOO library and put it in /tmp/foo-1/, so it looks like this:
/tmp/foo-1/foo.asd /tmp/foo-1/a.lisp
foo.asd has this:
(asdf:defsystem #:foo :serial t :components ((:file "a")))
Then I add the path to the central registry and load it:
(push #p"/tmp/foo-1/" asdf:*central-registry*) (asdf:load-system "foo")
Everything loads fine.
Oops, I need to upgrade, I better get version 2 and put it in /tmp/foo-2/, which looks like this:
/tmp/foo-2/foo.asd /tmp/foo-2/a.lisp /tmp/foo-2/b.lisp
foo.asd looks like this:
(asdf:defsystem #:foo :serial t :components ((:file "a") (:file "b")))
Then I add the path to central registry:
(push #p"/tmp/foo-2/" asdf:*central-registry*)
It seems to find the new system:
(asdf:system-source-directory "foo") => #p"/tmp/foo-2/"
However, when I try this:
(asdf:load-system "foo")
I end up with this error, which I don't really understand:
failed to find the TRUENAME of /tmp/foo-1/b.lisp: No such file or directory
Why does that happen? What's the best way to work around it?
I'm using ASDF 2.017 and a very recent SBCL from git. You can reproduce my scenario by unpacking http://xach.com/tmp/foofail.tgz and loading "foofail.lisp".
FWIW, I get the same error on ACL, so I believe this is an ASDF issue, and not SBCL-specific....
I haven't solved the problem, but when I look into the "foo" system object I see an interesting mismatch between the relative and absolute pathname slots:
A NEW ASDF-UTILITIES:SYSTEM @ #x100436e292 = #<ASDF-UTILITIES:SYSTEM "foo"> 0 Class --------> #<STANDARD-CLASS ASDF-UTILITIES:SYSTEM> 1 NAME ---------> A simple-string (3) "foo" 2 VERSION ------> symbol :--UNBOUND-- 3 LOAD-DEPENDENCIES -> symbol NIL 4 IN-ORDER-TO --> symbol NIL 5 DO-FIRST -----> ((ASDF-UTILITIES:COMPILE-OP (ASDF-UTILITIES:LOAD-OP))), a proper list with 1 element 6 INLINE-METHODS -> symbol NIL 7 PARENT -------> symbol NIL 8 RELATIVE-PATHNAME -> PATHNAME struct = #P"/Users/rpg/Downloads/foofail/foo-2/" 9 ABSOLUTE-PATHNAME -> PATHNAME struct = #P"/Users/rpg/Downloads/foofail/foo-1/" ....
This is probably the right place to look for the bug. I'm afraid that I will be in meetings all day, and am unlikely to get around to this in the near future...
Zach, would you mind blowing this into the launchpad?
thanks, r
