Leonardo Rodrigues de Mello 51d96088c1 (#20681) fix behaviour of delete_values ... The issue #20681 describe the error of delete() function removing the elements from the origin array/hash/string. This issue affected other delete functions. Because ruby delete and delete_if functions make destructive changes to the origin array/hash. The delete_undef_values removed elements from the origin hash and this is not the desired behaviour. To solve this, we should dup or clone the hash before using the delete or delete_if ruby functions. This fix the problem and add unit tests, so we could enforce this behaviour and prevent regressions.		2013-09-17 12:05:23 -03:00
