Hi list, I'm having trouble hot-upgrading asdf. My old setup was not checked out of a repository, but does have a file modified date of 2007-06-18. I also use asdf-binary-locations version "0.3.8". To begin with, I have created the following config file (~ is at c:/home) ~/.config/common-lisp/source-registry.conf (:source-registry (:directory "e:/src/ltk-0.90/") (:tree "c:/home/code/lisp/libs/") (:exclude "_darcs") :ignore-inherited-configuration) I then load-file asdf.lisp from Slime. My clisp-2.47 (non-cygwin Windows) is previously already running with asdf, asdf-binary-locations, and many systems loaded (and other random work done). I then tried to load a system that I could previously load just fine, in this case ironclad_0.27. CL-USER> (asdf:load-system :ironclad) ; loading system definition from C:\home\code\lisp\libs\ironclad_0.27\ironclad.asd into #<PACKAGE ASDF0> ;; Loading file C:\home\code\lisp\libs\ironclad_0.27\ironclad.asd ... ; registering #<SYSTEM :IRONCLAD #x26F7286D> as IRONCLAD ; registering #<SYSTEM IRONCLAD-TESTS #x26FE5225> as IRONCLAD-TESTS ;; Loaded file C:\home\code\lisp\libs\ironclad_0.27\ironclad.asd ; No value This gave the following error. TRANSLATE-PATHNAME: replacement pieces (NIL NIL (:DIRECTORY #1="home" #2="code" #3="lisp" #4="libs" #5="ironclad_0.27") "package" "fas" :NEWEST) do not fit into #P"C:\\Documents and Settings\\chewyong\\Local Settings\\Temporary Internet Files\\common-lisp\\**\\*.*" [Condition of type SIMPLE-ERROR] I browsed around in the stack trace (yes clisp stack traces are ugly), and looked deeper into this particular frame: ... 17: <1/1718> #<SYSTEM-FUNCTION TRANSLATE-PATHNAME> [1712] EVAL frame for form (TRANSLATE-PATHNAME (ASDF::DIRECTORIZE-PATHNAME-HOST-DEVICE ASDF::P) ASDF::ABSOLUTE-SOURCE ASDF::DESTINATION) Locals: ASDF::ABSOLUTE-SOURCE = #P"\\**\\*.*" ASDF::ROOT = #P"\\" ASDF::DESTINATION = #P"C:\\Documents and Settings\\chewyong\\Local Settings\\Temporary Internet..

In particular, I'm guessing that this is related to truenamize (has it taken the wrong branch?) with respect to (line 677 on my version of asdf.lisp) (ignore-errors (return (truename p))) Am I close enough? See the following: CL-USER> (truename (merge-pathnames #P"\\home\\code\\lisp\\libs\\ironclad_0.27\\package.fas")) ==> TRUENAME: File #1=#P"C:\\home\\code\\lisp\\libs\\ironclad_0.27\\package.fas" does not exist [Condition of type SYSTEM::SIMPLE-FILE-ERROR] My package.fas, due to asdf-binary-locations, has been stored previously in ~/code/lisp/libs/ironclad_0.27/clisp-2.47-win32-i386/package.fas I hope this is useful for fixing asdf + a-b-l hot upgrade. I can restart a new Lisp and give full backtraces or other further info, should that be necessary. Cheers.
