V8004. The use of 'if A {...} else if A {...}' pattern was detected. Potential logical error is present.
The analyzer has detected a potential error in a construction consisting of conditional instructions. The error is caused by repeated if conditions, which may result in the code within that branch becoming unreachable.
The example:
const (
MONDAY = "Monday"
TUESDAY = "Tuesday"
WEDNESDAY = "Wednesday"
THURSDAY = "Thursday"
FRIDAY = "Friday"
)
if day == MONDAY {
....
} else if day == TUESDAY {
....
} else if day == WEDNESDAY {
....
} else if day == THURSDAY {
....
} else if day == MONDAY {
....
}In the example, there are two if constructions with the same condition. If control flow reaches the second condition, it will always evaluate as false, making all code in the corresponding branch unreachable.
The fixed code:
if day == MONDAY {
....
} else if day == TUESDAY {
....
} else if day == WEDNESDAY {
....
} else if day == THURSDAY {
} else if day == FRIDAY {
....
