[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. Loaded subsystems: Unicode 1.28 with Unicode version 6.1.0 Python 1.1, target Intel x86/sse2 CLOS based on Gerd's PCL 2010/03/19 15:19:03 * (directory "/tmp/*.*") File-error in function TRUENAME: The file "/tmp/bad-link" does not exist. [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. However, it can only ever possibly tarnish but the person who insults.
