----------------------------------
Summary: Regression in script-defined functions
Key: JEXL-447
URL: https://issues.apache.org/jira/browse/JEXL-447
Project: Commons JEXL
Issue Type: Bug
Affects Versions: 3.6.0
Reporter: William Price
I have this existing behavior test in my code. It passes using 3.5.0:
{code:java}
let results = [...]
function expect(const left, const right, const equal) {
let correct = (left == right) === equal && !(left != right) === equal;
results.add(correct ?: `${left} ?= ${right}`);
return results;
}
function expectStrict(const left, const right, const equal) {
let correct = (left === right) === equal && !(left !== right) === equal;
results.add(correct ?: `${left} ?== ${right}`);
return results;
}
expect(1.0, 1, true);
expect(1.1, 1, false);
expect(1.1, 1.1d, true);
expect(1.1, 1.1f, false);
expect('a', 'a', true);
expect('a', 'b', false);
expect('1', 1, true);
expectStrict(1.0, 1.0, true);
expectStrict(1.0, 1.0d, true);
expectStrict(1.0, 1.0f, false);
expectStrict(1.0, 1, false);
expectStrict(1, '1', false); {code}
When I switched to a locally built version off the master branch (containing my
proposed fix for JEXL-446) it throws JexlException.Method:
{noformat}
unsolvable function/method 'expectStrict(Byte, Byte, Boolean) {noformat}
I turned the above into a JUnit test and ran `git bisect` between 3.5.0
(working) and the current head of master and bisect says the regression was
introduced in:
{noformat}
