Improvements to clang-tidy

--------------------------

New checks

^^^^^^^^^^

- New :doc:`bugprone-bad-signal-to-kill-thread

  <clang-tidy/checks/bugprone-bad-signal-to-kill-thread>` check.

  <clang-tidy/checks/bugprone-not-null-terminated-result>` check

  Finds function calls where it is possible to cause a not null-terminated

  result. Usually the proper length of a string is ``strlen(str) + 1`` or equal

  length of this expression, because the null terminator needs an extra space.

  Without the null terminator it can result in undefined behaviour when the

  string is read.

  result.

- New :doc:`bugprone-signed-char-misuse

  <clang-tidy/checks/bugprone-signed-char-misuse>` check.

  Finds ``signed char`` -> integer conversions which might indicate a programming

  error.

  Finds ``signed char`` to integer conversions which might indicate a

  programming error.

- New :doc:`cert-mem57-cpp

  <clang-tidy/checks/cert-mem57-cpp>` check.

  Checks if an object of type with extended alignment is allocated by using

  the default ``operator new``.

- New alias :doc:`cert-pos44-c

  <clang-tidy/checks/cert-pos44-c>` to

  :doc:`bugprone-bad-signal-to-kill-thread

  <clang-tidy/checks/bugprone-bad-signal-to-kill-thread>` was added.

- New :doc:`cert-oop58-cpp

  <clang-tidy/checks/cert-oop58-cpp>` check.

- New :doc:`cppcoreguidelines-init-variables

  <clang-tidy/checks/cppcoreguidelines-init-variables>` check.

  Checks whether there are local variables that are declared without an initial

  value.

- New :doc:`darwin-dispatch-once-nonstatic

  <clang-tidy/checks/darwin-dispatch-once-nonstatic>` check.

  Finds uses of deprecated Googletest APIs with names containing ``case`` and

  replaces them with equivalent APIs with ``suite``.

- Improved :doc:`hicpp-signed-bitwise

  <clang-tidy/checks/hicpp-signed-bitwise>` check.

  The check now supports the ``IgnorePositiveIntegerLiterals`` option.

- New :doc:`linuxkernel-must-use-errs

  <clang-tidy/checks/linuxkernel-must-use-errs>` check.

  Finds types that could be made trivially-destructible by removing out-of-line

  defaulted destructor declarations.

- The :doc:`modernize-use-using

  <clang-tidy/checks/modernize-use-using>` check now converts typedefs containing

  struct definitions and multiple comma-separated types.

- New :doc:`readability-make-member-function-const

  <clang-tidy/checks/readability-make-member-function-const>` check.

  Finds non-static member functions that can be made ``const``

  because the functions don't use ``this`` in a non-const way.

- New :doc:`readability-redundant-access-specifiers

  <clang-tidy/checks/readability-redundant-access-specifiers>` check.

  Finds classes, structs, and unions that contain redundant member

  access specifiers.

New aliases

^^^^^^^^^^^

- New alias :doc:`cert-pos44-c

  <clang-tidy/checks/cert-pos44-c>` to

  :doc:`bugprone-bad-signal-to-kill-thread

  <clang-tidy/checks/bugprone-bad-signal-to-kill-thread>` was added.

Changes in existing checks

^^^^^^^^^^^^^^^^^^^^^^^^^^

- Improved :doc:`bugprone-posix-return

  <clang-tidy/checks/bugprone-posix-return>` check.

  Now also checks if any calls to ``pthread_*`` functions expect negative return

  values.

  Now also checks if any calls to ``pthread_*`` functions expect negative

  return values.

- The 'objc-avoid-spinlock' check was renamed to :doc:`darwin-avoid-spinlock

  <clang-tidy/checks/darwin-avoid-spinlock>`

- Improved :doc:`hicpp-signed-bitwise

  <clang-tidy/checks/hicpp-signed-bitwise>` check.

  The check now supports the `IgnorePositiveIntegerLiterals` option.

- Improved :doc:`modernize-avoid-bind

  <clang-tidy/checks/modernize-avoid-bind>` check.

  The check now supports supports diagnosing and fixing arbitrary callables

  instead of only simple free functions. The `PermissiveParameterList` option

  has also been added to address situations where the existing fix-it logic

  would sometimes generate code that no longer compiles.

- The :doc:`modernize-use-equals-default

  <clang-tidy/checks/modernize-use-equals-default>` fix no longer adds

  semicolons where they would be redundant.

- New :doc:`readability-redundant-access-specifiers

  <clang-tidy/checks/readability-redundant-access-specifiers>` check.

- Improved :doc:`modernize-use-override

  <clang-tidy/checks/modernize-use-override>` check.

  Finds classes, structs, and unions that contain redundant member

  access specifiers.

  The check now supports the `AllowOverrideAndFinal` option to eliminate

  conflicts with `gcc -Wsuggest-override` or `gcc -Werror=suggest-override`.

- The :doc:`modernize-use-using

  <clang-tidy/checks/modernize-use-using>` check now converts typedefs

  containing struct definitions and multiple comma-separated types.

- Improved :doc:`readability-magic-numbers

  <clang-tidy/checks/readability-magic-numbers>` check.

  The check now supports the ``IgnoreBitFieldsWidths`` option to suppress

  The check now supports the `IgnoreBitFieldsWidths` option to suppress

  the warning for numbers used to specify bit field widths.

  The check was updated to eliminate some false positives (such as using

  class enumeration as non-type template parameters, or the synthetically

  computed lengh of a static user string literal.)

- New :doc:`readability-make-member-function-const

  <clang-tidy/checks/readability-make-member-function-const>` check.

  Finds non-static member functions that can be made ``const``

  because the functions don't use ``this`` in a non-const way.

- Improved :doc:`modernize-use-override

  <clang-tidy/checks/modernize-use-override>` check.

  The check now supports the ``AllowOverrideAndFinal`` option to eliminate

  conflicts with ``gcc -Wsuggest-override`` or ``gcc -Werror=suggest-override``.

  computed length of a static user string literal.)

- Improved :doc:`readability-redundant-member-init

  <clang-tidy/checks/readability-redundant-member-init>` check.

  The check  now supports the ``IgnoreBaseInCopyConstructors`` option to avoid

  The check  now supports the `IgnoreBaseInCopyConstructors` option to avoid

  `"base class 'Foo' should be explicitly initialized in the copy constructor"`

  warnings or errors with ``gcc -Wextra`` or ``gcc -Werror=extra``.

  warnings or errors with `gcc -Wextra` or `gcc -Werror=extra`.

- The :doc:`readability-redundant-string-init

  <clang-tidy/checks/readability-redundant-string-init>` check now supports a

  `StringNames` option enabling its application to custom string classes.

- Improved :doc:`modernize-avoid-bind

  <clang-tidy/checks/modernize-avoid-bind>` check.
