This is not a blocker. But the sooner we add warnings, the sooner we can turn them into errors. Recently, you and me added many uses of unsigned integer converters in the socket addresses parsing code. This fixed errors, and allowed to pass values that exceed the limit of corresponding signed integer type, but made the new code more error prone, because passing value that exceeds the limit of an unsigned integer type does not lead to exception. This is the main reason I created that PR now. The idea I proposed a year ago: capi-workgroup/api-evolution#49. |
