|
^^^^^^^^^^
|
|

- New :doc:`bugprone-unintended-char-ostream-output
|
|
<clang-tidy/checks/bugprone/unintended-char-ostream-output>` check.
|
|
|
|
Finds unintended character output from ``unsigned char`` and ``signed char`` to an
|
|
``ostream``.
|
|
|
|
- New :doc:`readability-ambiguous-smartptr-reset-call
|
|
<clang-tidy/checks/readability/ambiguous-smartptr-reset-call>` check.
|
|
|
|
Finds potentially erroneous calls to ``reset`` method on smart pointers when
|
|
the pointee type also has a ``reset`` method.
|
|
|
|
New check aliases
|
|
^^^^^^^^^^^^^^^^^
|
|
|
|
Changes in existing checks
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
- Improved :doc:`bugprone-string-constructor
|
|
<clang-tidy/checks/bugprone/string-constructor>` check to find suspicious
|
|
calls of ``std::string`` constructor with char pointer, start position and
|
|
length parameters.
|
|
|
|
- Improved :doc:`bugprone-unchecked-optional-access
|
|
<clang-tidy/checks/bugprone/unchecked-optional-access>` fixing false
|
|
positives from smart pointer accessors repeated in checking ``has_value``
|
|
and accessing ``value``. The option `IgnoreSmartPointerDereference` should
|
|
no longer be needed and will be removed. Also fixing false positive from
|
|
const reference accessors to objects containing optional member.
|
|
|
|
- Improved :doc:`bugprone-unsafe-functions
|
|
<clang-tidy/checks/bugprone/unsafe-functions>` check to allow specifying
|
|
additional C++ member functions to match.
|
|
|
|
- Improved :doc:`misc-const-correctness
|
|
<clang-tidy/checks/misc/const-correctness>` check by adding the option
|
|
`AllowedTypes`, that excludes specified types from const-correctness
|
|
checking and fixing false positives when modifying variant by ``operator[]``
|
|
with template in parameters.
|
|
|
|
- Improved :doc:`misc-redundant-expression
|
|
<clang-tidy/checks/misc/redundant-expression>` check by providing additional
|
|
examples and fixing some macro related false positives.
|
|
|
|
- Improved :doc:`modernize-use-ranges
|
|
<clang-tidy/checks/modernize/use-ranges>` check by updating suppress
|
|
warnings logic for ``nullptr`` in ``std::find``.
|
|
|
|
- Improved :doc:`modernize-use-std-numbers
|
|
<clang-tidy/checks/modernize/use-std-numbers>` check to support math
|
|
functions of different precisions.
|
|
|
|
- Improved :doc:`misc-use-internal-linkage
|
|
<clang-tidy/checks/misc/use-internal-linkage>` check by fix false positives
|
|

|
|
|
|
- Improved :doc:`modernize-use-default-member-init
|
|
<clang-tidy/checks/modernize/use-default-member-init>` check by matching
|
|
``constexpr`` and ``static`` values on member initialization.
|
|
|
|
- Improved :doc:`performance/unnecessary-value-param
|
|
<clang-tidy/checks/performance/unnecessary-value-param>` check performance by
|
|
tolerating fix-it breaking compilation when functions is used as pointers
|
|
to avoid matching usage of functions within the current compilation unit.
|
|
|
|
- Improved :doc:`performance-move-const-arg
|
|
<clang-tidy/checks/performance/move-const-arg>` check by fixing false negatives
|
|
on ternary operators calling ``std::move``.
|
|
|
|
