= and byte arrays

[Steven Devijver]

Given two byte arrays that have the same content (value) the code
below runs without errors:

(def ba1 (...))
(def ba2 (...))

(assert (not= ba1 ba2))
(assert (= (String. ba1) (String ba2)))

Is this as expected?

[Laurent PETIT]

yes, since arrays are mutables, the only equality semantics that's stable over the application timeline is object identity equality. Thus = on arrays is based on java's ==

(= (seq ba1) (seq ba2)) will give you a value (byte-by-byte)
comparison.
