bugprone-dangling-handle
|
|
========================
|
|
|
|
Detect dangling references in value handles like
|
|
``std::experimental::string_view``.
|
|
These dangling references can be a result of constructing handles from temporary
|
|
values, where the temporary is destroyed soon after the handle is created.
|
|
|
|
Examples:
|
|
|
|
.. code-block:: c++
|
|
|
|
string_view View = string(); // View will dangle.
|
|
string A;
|
|
View = A + "A"; // still dangle.
|
|
|
|
vector<string_view> V;
|
|
V.push_back(string()); // V[0] is dangling.
|
|
V.resize(3, string()); // V[1] and V[2] will also dangle.
|
|
|
|
string_view f() {
|
|
// All these return values will dangle.
|
|
return string();
|
|
string S;
|
|
return S;
|
|
char Array[10]{};
|
|
return Array;
|
|
}
|
|
|
|
Options
|
|
-------
|
|
|
|
.. option:: HandleClasses
|
|
|
|
A semicolon-separated list of class names that should be treated as handles.
|
|
By default only ``std::experimental::basic_string_view`` is considered.
