[Feature] Add FE constant folding for cosine_similarity and standardize test patterns by Copilot · Pull Request #60403 · apache/doris

Copilot · 2026-01-31T08:25:48Z

Adds FE constant folding support for cosine_similarity and replaces try-catch blocks in regression tests with the standard test{sql, exception} pattern.

FE Constant Folding

New ArrayArithmetic.java executable class with @ExecFunction annotation
Registered in ExpressionEvaluator.java for constant folding during query optimization
Implements null element validation, array size checks, and zero vector handling

@ExecFunction(name = "cosine_similarity")
publicstaticExpressioncosineSimilarity(ArrayLiteralarray1, ArrayLiteralarray2) {
// Computes: dot(x, y) / (||x|| * ||y||)// Returns FloatLiteral
}

Test Pattern Standardization

Replaced 9 try-catch blocks with test{sql, exception} pattern in test_array_distance_functions.groovy:

// Beforetry {
sql "SELECT cosine_similarity([1, 2], [1, 2, 3])"
} catch (Exception ex) {
assert("${ex}".contains("different input element sizes"))
}
// After
test {
sql "SELECT cosine_similarity([1, 2], [1, 2, 3])"
exception "function cosine_similarity have different input element sizes"
}

Thank you for your contribution to Apache Doris.
Don't know what should be done next? See How to process your PR.

Please clearly describe your PR:

What problem was fixed (it's best to include specific error reporting information). How it was fixed.
Which behaviors were modified. What was the previous behavior, what is it now, why was it modified, and what possible impacts might there be.
What features were added. Why was this function added?
Which code was refactored and why was this part of the code refactored?
Which functions were optimized and what is the difference before and after the optimization?
