From: dstein64 on 20 Apr 2008 01:23 I have a file with a bunch of load statements and asdf:operate statements that I use to quickly load a project I am working on. One of the systems I am using, LISA, always prompts a message that basically says beware, package locks... I always click 'ignore-all' to continue loading. I do not mind, but I am preparing this for a class, and I would like to know what I can put in my code to prevent this warning from appearing. Thanks.

I noticed this package lock as well, but it didn't really bother me. Now since you asked, I had a look at it: One way to solve this is to change the `class-parsing-error' definition in src/core/conditions.lisp to not use `class-name' as a reader. That resolves the bug (note: You may introduce a new one this way, but I don't think so.) This is a bug, and you should report such findings (well, one of us should). HTH Albert

If this is SBCL, you might try sb-ext:disable-package-locks or sb-ext:with-unlocked-packages. See http://www.sbcl.org/manual/Package-Lock-Dictionary.html#Package-Lock-Dictionary for details. The correct fix is to stop LISA from redefining symbols outside its package. This may be as simple as having LISA's package shadow a few symbols. - Daniel |
