----------------------------------
Summary: Wrong Script$Curried creation when script.curry() method
is called inside script
Key: JEXL-270
URL: https://issues.apache.org/jira/browse/JEXL-270
Project: Commons JEXL
Issue Type: Bug
Affects Versions: 3.1
Reporter: Dmitri Blinov
I have noticed that when i call lambda.curry() method inside the script, then
the curried lamba is created with wrong source text. I expect the source text
of the curried lambda to be always equal to that of original, but that is not
the case now. To illustrate this I have prepared two testcases, from which
{{testCurryScript2}} fails with
[ERROR] Failures:
[ERROR] LambdaTest.testCurryScript2:307 expected:<true> but was:<false>
{code:java}
@Test
public void testCurryScript() throws Exception {
JexlEngine jexl = new Engine();
JexlScript base = jexl.createScript("(x, y, z)->{ x + y + z }");
String text = base.toString();
JexlScript script = base.curry(5, 15);
Assert.assertEquals(text, script.toString());
JexlEvalContext ctxt = new JexlEvalContext();
ctxt.set("s", base);
script = jexl.createScript("return s");
Object result = script.execute(ctxt);
Assert.assertEquals(text, result.toString());
script = jexl.createScript("return s.curry(1)");
result = script.execute(ctxt);
Assert.assertEquals(text, result.toString());
}
@Test
public void testCurryScript2() throws Exception {
JexlEngine jexl = new Engine();
JexlScript base = jexl.createScript("var base = 0; var sum = (y, z) ->
{var x = base; x += y; return x}; base = 2; var y = sum.curry(1); y.toString()
eq sum.toString()");
Object result = base.execute(null);
Assert.assertEquals(Boolean.TRUE, result);
}
{code}
