append
possibly assigns to a wrong variable CRT-D0001365 // We should go for the primary canddiates first, but the secondary candidates are also valid
366 var candidates []*fly.Machine
367 if allowSecondaryRegion {
368 candidates = append(primaryCandidates, secondaryCandidates...)369 } else {
370 candidates = primaryCandidates

The builtin function append
returns the updated slice after the append operation.
This resulting slice is usually assigned back to the same variable that contained
the original slice to which new values were appended.
x = []int{1, 3, 5}
append(x, 7) // returns the value []int{1, 3, 5, 7}. This is usually assigned back to x
x := []int{}
y := []int{}
x = append(y, 1) // possibly wrong
x = []int{1, 3, 5}
x = append(x, 7)
x := []int{}
y := []int{}
y = append(y, 1) // append 1 to y
