This change avoids lots of false positives for Coverity's CHECKED_RETURN warning, caused by NS_WARN_IF's current use in both statement-style and expression-style. In the case where the code within the NS_WARN_IF has side-effects, I made the following change. > NS_WARN_IF(NS_FAILED(FunctionWithSideEffects())); > --> > Unused << NS_WARN_IF(NS_FAILED(FunctionWithSideEffects())); In the case where the code within the NS_WARN_IF lacks side-effects, I made the following change. > NS_WARN_IF(!condWithoutSideEffects); > --> > NS_WARNING_ASSERTION(condWithoutSideEffects, "msg"); This has two improvements. - The condition is not evaluated in non-debug builds. - The sense of the condition is inverted to the familiar "this condition should be true" sense used in assertions. A common variation on the side-effect-free case is the following. > nsresult rv = Fn(); > NS_WARN_IF_(NS_FAILED(rv)); > --> > DebugOnly<nsresult rv> = Fn(); > NS_WARNING_ASSERTION(NS_SUCCEEDED(rv), "Fn failed"); --HG-- extra : rebase_source : 58788245021096efa8372a9dc1d597a611d45611 |
