`include-what-you-use` diagnostics, in practice, are specific to
the environment's compiler and standard library. Update includes
to satisfy IWYU for our CI job under Debian 13. Some patterns:
* Types named in virtual `override` signatures no longer require
includes since the overridden signature already names them.
* A function argument's type needs to be included even if its constructor
is called only by implicit conversion. For example, constructing a
`std::function` from a lambda now requires `<functional>`.
* Some prior mysterious `<type_traits>` inclusions are no longer required.
The explicit initialization with empty paths from commit 57bdc1a2f7
(cmState: Compute and store directory components., 2015-05-04,
v3.3.0-rc1~61^2~4) has not been needed since commit 6afd35b98a (cmState:
remove unused code, 2016-06-16, v3.7.0-rc1~90^2).
Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`, now with "east const" enforcement.
Use `clang-format` version 18.

Issue: #26123
The behaviors controlled by options `GRAPHVIZ_GENERATE_PER_TARGET` and
`GRAPHVIZ_GENERATE_DEPENDERS` were broken by commit 553658393c (Graphviz:
added test suite, fixes, enhancements, 2019-10-08, v3.17.0-rc1~615^2).
It had not been covered in the test suite previously, and those changes
left out checks for these features from the `default_options` case.
Implement the previously-existing behavior in the new graphviz
generation engine added by the above-mentioned commit.
Fixes: #20928
The `std::endl` manipulator, except inserting `\n` character, also
performs `os.flush()`, which may lead to undesired effects (like
disk I/O in the middle of forming data strings). For the
`std::stringstream` it also has no meaning.
* replace multiple `operator<<` calls on a string literal w/
the only call and the only (bigger) string literal;
* replace one character string literal used in `operator<<`
w/ a char literal.
* Added a fairly comprehensive test suite
* Separated the graph traversal logic from the Graphviz generation
code by introducing a new class, cmLinkItemsGraphVisitor{.h,cxx}
* Made the graph traversal logic less ad-hoc by using existing
methods in the GlobalGenerator; this fixed a few bugs
* Added support for new target types: custom targets, object
and unknown libraries
* Improved support for ALIAS libraries by showing the alias(es)
in the graph
* Introduced new flags to control those new libraries (consistent
with existing flags)
* Updated the documentation
* Removed useless setting to set graph type in dot file
* Improved the node/edge shapes (nicer, more consistent)
* Added a legend to the graph
* Some refactoring and cleanup of the Graphviz generation code
* Added test and fix for issue 19746
Set the MinTypeNameLength option to an impossibly high value in order
to limit the diagnostics to iterators. Leave new expressions and cast
expressions for later.
This patch is generated by a python script that uses regular expressions to
search for string concatenation patterns of the kind
```
std::string str = <ARG0>;
str += <ARG1>;
str += <ARG2>;
...
```
and replaces them with a single `cmStrCat` call
```
std::string str = cmStrCat(<ARG0>, <ARG1>, <ARG2>, ...);
```
If any `<ARGX>` is itself a concatenated string of the kind
```
a + b + c + ...;
```
then `<ARGX>` is split into multiple arguments for the `cmStrCat` call.
If there's a sequence of literals in the `<ARGX>`, then all literals in the
sequence are concatenated and merged into a single literal argument for
the `cmStrCat` call.
Single character strings are converted to single char arguments for
the `cmStrCat` call.
`std::to_string(...)` wrappings are removed from `cmStrCat` arguments,
because it supports numeric types as well as string types.
`arg.substr(x)` arguments to `cmStrCat` are replaced with
`cm::string_view(arg).substr(x)`
An old workaround for `std::allocator_traits<>::value_type` lints from
IWYU on `std::vector<>` usage breaks IWYU's handling of `<memory>`.
Convert the workaround to use the same approach we already use for a
workaround of `std::__decay_and_strip<>::::__type` lints. Then update
the `<memory>` inclusions to follow the now-correct IWYU lints.
After changing the ``cmGeneratedFileStream`` methods to accept
``std::string const&`` instead of ``const char*`` we don't
need to call ``std::string::c_str`` anymore when passing
a ``std::string`` to a ``cmGeneratedFileStream`` method.
This patch removes all redundant ``std::string::c_str``
calls when passing a string to a ``cmGeneratedFileStream`` method.
It was generated by building CMake with clang-tidy enabled using
the following options:
-DCMAKE_CXX_CLANG_TIDY=/usr/bin/clang-tidy-4.0;-checks=-*,readability-redundant-string-cstr;-fix;-fix-errors
Add an index to Change cmLocalGenerator::GeneratorTargets for faster lookup by
name.
Also changed a bunch of uses of cmLocalGenerator::GetGeneratorTargets() to take
const references instead of copying the vector.
Represent generator targets as a map (name -> target) to make name lookups more
efficient instead of looping through the entire vector to find the desired one.
