Summary: (Copied from https://www.internalfb.com/diff/D46606060) This diff makes its files safe for use with -Wimplicit-fallthrough. Now that we're using C+20 there's no reason not to use this C++17 feature to make our code safer. It's currently possible to write code like this: ``` switch(x){ case 1: foo1(); case 2: foo2(); break; case 3: foo3(); } ``` But that's scary because we don't know whether the fallthrough from case 1 was intentional or not. The -Wimplicit-fallthrough flag will make this an error. The solution is to either fix the bug by inserting break or indicating intention by using [[fallthrough]]; (from C++17). ``` switch(x){ case 1: foo1(); [[fallthrough]]; // Solution if we intended to fallthrough break; // Solution if we did not intend to fallthrough case 2: foo2(); break; case 3: foo3(); } ``` Pull Request resolved: https://github.com/facebook/rocksdb/pull/11663 Test Plan: Existing tests Reviewed By: jowlyzhang Differential Revision: D47961248 Pulled By: jaykorean fbshipit-source-id: 0d374c721bf1b328c14949dc5c17693da7311d03 |
