In the process of making a test for bug1335323, I discovered that the top-level call to look up the system in LOAD-SYSTEM/OPERATE, is FIND-COMPONENT, not FIND-SYSTEM, so that the REINITIALIZE-SOURCE-REGISTRY-AND-RETRY restart is not available. Also, for some reason, I am unable to find the "force1" subsystem of "test-asdf", although "test-asdf" is found correctly:
1: (OPERATE LOAD-OP "test-asdf/force1") 2: (FIND-COMPONENT NIL "test-asdf/force1") 3: (FIND-COMPONENT "test-asdf/force1" NIL) 4: (FIND-SYSTEM "test-asdf/force1" NIL) 5: (FIND-SYSTEM "test-asdf" NIL) 5: FIND-SYSTEM returned #<PACKAGE-INFERRED-SYSTEM "test-asdf"> 5: (FIND-SYSTEM "test-asdf" NIL) 5: FIND-SYSTEM returned #<PACKAGE-INFERRED-SYSTEM "test-asdf"> 4: FIND-SYSTEM returned NIL 3: FIND-COMPONENT returned NIL 2: FIND-COMPONENT returned NIL
Any idea why this is happening? It's after an attempt to clear the ASDF cache, and I wonder if that's implicated -- maybe just smashing the *asdf-cache* isn't correct. When I first call FIND-SYSTEM, I do find the system:
; Loading system definition for test-asdf from /Users/rpg/lisp/asdf/test/test-asdf.asd ;; loading #P"/Users/rpg/lisp/asdf/test/test-asdf.asd" ; Registering #<SYSTEM "test-asdf"> ; Registering #<SYSTEM "test-asdf/all"> ; Registering #<SYSTEM "test-asdf/1"> ; Registering #<SYSTEM "test-asdf/2"> ; Registering #<SYSTEM "test-asdf/4"> ; Registering #<SYSTEM "test-asdf/test9-1"> ; Registering #<SYSTEM "test-asdf/test-module-depend"> ; Registering #<SYSTEM "test-asdf/test9-2"> ; Registering #<SYSTEM "test-asdf/test9-3"> ; Registering #<SYSTEM "test-asdf/test-source-directory-1"> ; Registering #<SYSTEM "test-asdf/test-source-directory-2"> ; Registering #<SYSTEM "test-asdf/bundle-1"> ; Registering #<SYSTEM "test-asdf/bundle-2"> ; Registering #<SYSTEM "test-asdf/force"> ; Registering #<SYSTEM "test-asdf/force1"> Clearing the caches and finding.....
I have pushed my bug1335323 topic branch to cl.net, since I could use some help with it, in case anyone has the time to examine it. (whoops. I can see now that I should be keeping the cache entries for ASDF, POIU, and their components; that's probably a bug, since if you are changing ASDF you're probably better off unwinding completely and starting over, instead of trying to handle an error)
