* [clang-tidy] Fix readability-redundant-string-init for c++17/c++2aMitchell Balan2019-11-191-1/+10
| | | | | | | | | | | | | | | | | | | Summary: `readability-redundant-string-init` was one of several clang-tidy checks documented as failing for C++17. (The failure mode in C++17 is that it changes `std::string Name = ""`; to `std::string Name = Name;`, which actually compiles but crashes at run-time.) Analyzing the AST with `clang -Xclang -ast-dump` showed that the outer `CXXConstructExprs` that previously held the correct SourceRange were being elided in C++17/2a, but the containing `VarDecl` expressions still had all the relevant information. So this patch changes the fix to get its source ranges from `VarDecl`. It adds one test `std::string g = "u", h = "", i = "uuu", j = "", k;` to confirm proper warnings and fixit replacements in a single `DeclStmt` where some strings require replacement and others don't. The readability-redundant-string-init.cpp and readability-redundant-string-init-msvc.cpp tests now pass for C++11/14/17/2a.

| | | | | | | | | | | | | | | | | | | string types to fix Summary: This patch adds a feature requested in https://reviews.llvm.org/D69238 to enable `readability-redundant-string-init` to take a list of strings to apply the fix to rather than hard-coding `basic_string`. It adds a `StringNames` option of semicolon-delimited names of string classes to which to apply this fix. Tests ensure this works with test class out::TestString as well as std::string and std::wstring as before. It should be applicable to llvm::StringRef, QString, etc. Note: This commit was previously reverted due to a failing unit test. That test has been fixed in this version.

* [clang-tidy] modernize-use-override new option AllowOverrideAndFinalMitchell Balan2019-11-151-2/+6
| | | | | | | | | | | | | | | | | | | Summary: In addition to adding `override` wherever possible, clang-tidy's `modernize-use-override` nicely removes `virtual` when `override` or `final` is specified, and further removes override when final is specified. While this is great default behavior, when code needs to be compiled with gcc at high warning levels that include `gcc -Wsuggest-override` or `gcc -Werror=suggest-override`, clang-tidy's removal of the redundant `override` keyword causes gcc to emit a warning or error. This discrepancy / conflict has been noted by others including a comment on Stack Overflow and by Mozilla's Firefox developers. This patch adds an AllowOverrideAndFinal option defaulting to 0 - thus preserving current behavior - that when enabled allows both `override` and `final` to co-exist, while still fixing all other issues. The patch includes a test file verifying all combinations of virtual/override/final, and mentions the new option in the release notes.

* [ClangTidy] Separate tests for infrastructure and checkersDmitri Gribenko2019-10-111-0/+141
Summary: This change moves tests for checkers and infrastructure into separate directories, making it easier to find infrastructure tests. Tests for checkers are already easy to find because they are named after the checker. Tests for infrastructure were difficult to find because they were outnumbered by tests for checkers. Now they are in a separate directory.
