[postmodern-devel] patch for array slicing
by Nicolas Martyanoff 25 Apr '11

Hi, I wrote a tiny patch to add support for array slicing: So now: (:[] #(1 2 4 8) 3) → "(ARRAY[1,2,4,8])[3]" (:[] #(1 2 4 8) 2 4) → "(ARRAY[1,2,4,8])[2:4]" I hope you will find it useful. Best regards, -- Nicolas Martyanoff http://codemore.org khaelin(a)gmail.com

[postmodern-devel] bug in the array interpreter
by Nicolas Martyanoff 25 Apr '11

I think I found a pretty nasty bug; the array parser loop foreven on empty arrays, eating all the RAM it can. Triggering it is really simple, just select an empty array. The effect is directly visible with: (funcall (cl-postgres::read-array-value #'parse-integer) "{}") I think there's something wrong in the following sexp in READ-ARRAY-VALUE: (loop :for x := arr :then (car x) :while (listp x) :collect (length x)) If ARR is nil, it loops forever since both (listp nil) and (car nil) yield t. I'm not sure I understand how the code works for multi-dimensional arrays, so I'd prefer not to break something trying a fix; would you mind fix it ? Thank you.
