IO18141: TITLE: TDI IMPLEMENTATION OF THE SPLICE METHOD IS INCONSISTENT WITH THE ECMASCRIPT SPECIFICATION

APAR status

• Closed as program error.

Error description

• Title:  TDI implementation of the splice method is inconsistent
  with
  the ECMAScript specification.
  
  Description:
  The implementation TDI uses makes splice return the original
  array
  without the deleted element. This is significantly different
  than what
  stands in the specification.  There is a difference between the
  ECMAScript specification for the method "splice" for arrays.
  Section 15.4.4.12 of the
  http://www.ecmascript.org/docs/tc39-2009-043.pdf details the
  specification.
  
  Steps to Duplicate:
  Create an Assemblyline with an EmptyScript.  Paste the script
  below in
  the EmptyScript component, and run the Assemblyline.  The
  results will
  not match the definition of the .splice method.
  
  var myFish = ["angel", "clown", "mandarin", "surgeon"];
  
  task.logmsg(">> TEST 1");
  //removes 0 elements from index 2, and inserts "drum"
  var removed = myFish.splice(2, 0, "drum");
  task.logmsg("removed = " +removed);
  task.logmsg("myFish = " +myFish);
  //myFish is ["angel", "clown", "drum", "mandarin", "surgeon"]
  //removed is [], no elements removed
  task.logmsg("------");
  
  task.logmsg(">> TEST 2");
  //removes 1 element from index 3
  removed = myFish.splice(3, 1);
  task.logmsg("removed = " +removed);
  task.logmsg("myFish = " +myFish);
  //myFish is ["angel", "clown", "drum", "surgeon"]
  //removed is ["mandarin"]
  task.logmsg("------");
  
  task.logmsg(">> TEST 3");
  //removes 1 element from index 2, and inserts "trumpet"
  removed = myFish.splice(2, 1, "trumpet");
  task.logmsg("removed = " +removed);
  task.logmsg("myFish = " +myFish);
  //myFish is ["angel", "clown", "trumpet", "surgeon"]
  //removed is ["drum"]
  task.logmsg("------");
  
  task.logmsg(">> TEST 4");
  //removes 2 elements from index 0, and inserts "parrot",
  "anemone" and
  "blue"
  removed = myFish.splice(0, 2, "parrot", "anemone", "blue");
  task.logmsg("removed = " +removed);
  task.logmsg("myFish = " +myFish);
  //myFish is ["parrot", "anemone", "blue", "trumpet", "surgeon"]
  //removed is ["angel", "clown"]
  task.logmsg("------");
  
  Desired Behavior:  As noted in the test script above, the
  .splice
  method should return the items removed from the array.
  
  Environment: 7.1.1
  

Local fix

• 1787
  

Problem summary

• TDI implementation of the splice method should be consisitent
  with the ECMA Script specifications.
  

Problem conclusion

• This is a bug in the TDI code and has been fixed. The official
  fix will be made available in 7.1.1-TIV-TDI-FP0003.
