[cmucl-imp] Please kill those notes
by Faré 29 Jan '13

Why do these output a compilation note about some unused macroexpanded case? How do I muffle the notes? (defmethod print-object ((o operation) stream) (print-unreadable-object (o stream :type t :identity nil) (ignore-errors (format stream "~{~S~^ ~}" (operation-original-initargs o))))) (defmethod perform-with-restarts ((o load-op) (c cl-source-file)) (loop (restart-case (return (call-next-method)) (try-recompiling () :report (lambda (s) (format s "Recompile ~a and try loading it again" (component-name c))) (perform (find-operation o 'compile-op) c))))) —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org *EULA: By reading or responding to this message you agree that all my stated or unstated opinions are correct.* "EULA" — patent pending.

[cmucl-imp] ASDF support for deferred warnings in CMUCL?
by Faré 26 Jan '13

26 Jan '13

Dear CMUCL developers, I've been adding support for ASDF to save deferred warnings (typically, forward function references) in a file, so that if you do an incremental compilation, warnings from previously compiled files are still correctly handled at the end of the virtual with-compilation-unit. I've added support for SBCL and CCL myself, which was made much easier by being able to read the source code to their compilers, but I don't feel like groveling through four more free sofware compilers. Would you be interested in implementing the same feature for CMUCL, or at least in guiding me on how to do so? The code is mainly in asdf/lisp-build.lisp functions reify-deferred-warnings unreify-deferred-warnings reset-deferred-warnings. http://common-lisp.net/gitweb?p=projects/asdf/asdf.git Best regards, —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org Better, faster, cheaper — pick any two.

Re: [cmucl-imp] Upgrade issues
by Faré 22 Jan '13

22 Jan '13

CMUCL is one of the three implementations, together with ABCL and CLISP, where I ultimately punted on ASDF hot-upgrade, by just trying to rename away the ASDF package if it's too old. My package surgery looks like it works, but it looks like CMUCL refuses to invalidate old CLOS methods when I fmakunbound an object, and/or refuses to invalidate them in some caches. Therefore, the old methods keep getting called and the upgrade fails in weird ways. Trying to unintern the symbols for individual offending functions doesn't work either; I don't remember the symptoms. It's too late to fix the old ASDF so it is easier to upgrade, but maybe there are declarations I can put in the current ASDF to prevent some of these "optimizations" to be in place? If you're interested in fixing this kind of issues, I can try to come up with reduced examples. Anyway, please test the latest ASDF with CMUCL, I think it's ripe for release, except for those upgrade woes. I'd like your feedback considering the massive amount of hacking that happened. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org Antivirus alert: file .signature infected by signature virus.

[cmucl-imp] DIRECTORY and symlinks
by Helmut Eller 03 Dec '12

03 Dec '12

When a directory contains a symbolic link to a non-existent file DIRECTORY signals an error. E.g. create a link like this: bash> cd /tmp ; ln -s non-existent bad-link bash> ls -l bad-link lrwxrwxrwx 1 helmut helmut 12 Dec 1 15:29 bad-link -> non-existent and then in CMUCL: CMU Common Lisp snapshot-2012-10 (20C Unicode), running on ix With core: /opt/cmucl/cmucl-2012-10/lib/cmucl/lib/lisp-sse2.core Dumped on: Sun, 2012-09-30 08:33:59+02:00 on lorien2 See <http://www.cmucl.org/> for support information.

[Condition of type KERNEL:SIMPLE-FILE-ERROR] Is that necessary? Or is there some (portable) way to avoid the error? Helmut

[cmucl-imp] ENOUGH-NAMESTRING and .~N~
by Helmut Eller 02 Dec '12

02 Dec '12

Create a file .my-file.~1~ like so: bash> mkdir -p /tmp/my-dir; touch /tmp/my-dir/.my-file.~1~ then in CMUCL: * (defparameter *my-dir* (truename "/tmp/my-dir/")) * (enough-namestring (car (directory *my-dir*)) *my-dir*) Error in function (FLET LISP::LOSE LISP::UNPARSE-UNIX-ENOUGH): #P"/tmp/my-dir/.my-file.~1~" cannot be represented relative to #P"/tmp/my-dir/" [Condition of type SIMPLE-ERROR] That's odd, no?

[cmucl-imp] CMUCL bug when compiling defclass
by Faré 01 Dec '12

01 Dec '12

While trying to upgrade ASDF from 2.017 to 2.26 on CMUCL 20c, we observed a bug that we believe is due to how CMUCL compiles defclass. CMUCL fails on the defmethod shared-initialize :after, because, says it, operation-forced-not is not a defined function. Yet the function is defined two forms above as an accessor in defclass operation, and it doesn't error out when compiling the file from clean rather than from a situation where a previous asdf was loaded. Presumably, CMUCL fails to properly process the defclass because it believes the defclass already happened. Yet, and this is probably a second bug: why should an undefined function in this case be an ERROR and not just a style-warning? If I fix this problem, then similar issues crop up with %system-source-file. I issued a workaround in ASDF 2.26.5. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org An insult may sometimes adequately fit the person who is insulted.
