I noticed strange behavior in the sort function, I was sorting key
value tuples and ran into the following:
when sorting 2 item vectors such as [1 [1 2 3]] sort works fine:
(println
(sort
(map
(fn [x] [(int (* (Math/random) 10)) x]) (for [x (range 4)]
[1 2 3]))))
output:
([6 [1 2 3]] [6 [1 2 3]] [6 [1 2 3]] [6 [1 2 3]])
however, if the second item is a list, e.g:
(println
(sort
(map
(fn [x] [(int (* (Math/random) 10)) x]) (for [x (range
100)] `(1 2 3)))))
the following exception can occur, this happens more frequently for
larger ranges, for range of 4, it may or may run and produce the
result, however with a range of 100 the exception occurs consistently:
Exception in thread "main" java.lang.RuntimeException:
