Function shouldCatchPanic

pkg/sql/colexecerror/error.go:193–221

shouldCatchPanic checks whether the panic that was emitted from panicEmittedFrom line of code (which contains the full path to the function where the panic originated) should be caught by the vectorized engine. The vectorized engine uses the panic-catch mechanism of error propagation, so we need to

(panicEmittedFrom string)

// panicEmittedFrom must be trimmed to not have any white spaces in the prefix.
func shouldCatchPanic(panicEmittedFrom string) bool {
	// In crdb_test builds we do not catch runtime panics even if they originate
	// from within the vectorized execution engine. These panics probably
	// represent bugs in vectorized execution, and we want them to fail loudly in
	// tests (but not in production clusters).
