[Sbcl-help] Reader pathname issue?

From: Dave Roberts <ldave@dr...> - 2004-03-01 06:02

So in the course of working with UFFI to write some code to deal with
external functions, I ran across what is perhaps a bug in the reader for
pathnames. I'm still new to Lisp, so please educate me if this is not a
bug:

* #p"/home/dave/lispstuff/uffi-1.4.6"

#P"/home/dave/lispstuff/uffi-1.4"

This is using SBCL 0.8.6. Basically, when entering a literal pathname,
SBCL drops the trailing ".6" for some unknown reason. I have tried it
with some other names and suffixes and can't see any pattern in the
short amount of testing.

So, bug or pilot error?

Thanks,

-- Dave

A bug, which should be fixed in sbcl-0.8.8.

The problem lay in a confusion in parsing for the version component of
pathnames (it would lose when the final part of the pathname was
".<int>".

One comment: are you sure you don't mean the pathname
#p"/home/dave/lispstuff/uffi-1.4.6/"?  The trailing slash can make
quite a significant difference.

Cheers,

Christophe
