py: Allow bytes/bytearray/array to be init'd by buffer protocol objects. Behaviour of array initialisation is subtly different for bytes, bytearray and array.array when argument has buffer protocol. This patch gets us CPython conformant (except we allow initialisation of array.array by buffer with length not a multiple of typecode). 2014-12-04 15:46:14 +00:00			`# test construction of bytearray from different objects`

py/objarray: bytearray: Allow 2nd/3rd arg to constructor. If bytearray is constructed from str, a second argument of encoding is required (in CPython), and third arg of Unicode error handling is allowed, e.g.: bytearray("str", "utf-8", "strict") This is similar to bytes: bytes("str", "utf-8", "strict") This patch just allows to pass 2nd/3rd arguments to bytearray, but doesn't try to validate them to not impact code size. (This is also similar to how bytes constructor is handled, though it does a bit more validation, e.g. check that in case of str arg, encoding argument is passed.) 2018-09-03 19:52:35 +01:00			`print(bytearray('1234', 'utf-8'))`
