* chore: fix cpplint 'include_what_you_use' warnings Typically by including <memory>, <utility> etc. * chore: fix 'static/global string constant' warning Use C style strings instead of std::string. Style guide forbids non-trivial static / global variables. https://google.github.io/styleguide/cppguide.html#Static_and_Global_Variables /home/charles/electron/electron-gn/src/electron/script/cpplint.js * refactor: remove global string variables. Fix 'global string variables are not permitted' linter warnings by using the base::NoDestructor<> wrapper to make it explicit that these variables are never destroyed. The style guide's take on globals with nontrivial destructors: https://google.github.io/styleguide/cppguide.html#Static_and_Global_Variables * fix: initializer error introduced in last commit * fix: remove WIP file that was included by accident * fix: include order * fix: include order * fix: include order * fix: include order, again
