* Revise C++ coding style using clang-format-15Kitware Robot2023-01-183-26/+22
| | | | | | | | | | | | | | Run the `clang-format.bash` script to update all our C and C++ code to a new style defined by `.clang-format`. Use `clang-format` version 15. * If you reached this commit for a line in `git blame`, re-run the blame operation starting at the parent of this commit to see older history for the content. * See the parent commit for instructions to rebase a change across this style transition commit. Fixes: #24315

| * cm/filesystem: Fix crash with pre-C++11 std::string GNU ABI in C++17Brad King2022-10-201-10/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `remove_filename` and `replace_extension` methods compute an offset between the whole path in a `std::string` and a part of a path in a `std::string_view`. This is done by subtracting their `.data()` pointers. However, C++17 adds a non-const `.data()` through which modification of the string is allowed. This means the copy-on-write implementation used by the pre-C++11 std::string GNU ABI must reallocate if the string has been copied. Our subtraction then computes an offset between two different allocations, which is undefined behavior. The workaround in commit b3ca4f9ad1 (cm/filesystem: Work around crash when compiled for CYGWIN/MSYS runtime, 2021-04-22, v3.21.0-rc1~271^2~2) avoided the problem by calling the non-const `.data()` to reallocate before constructing the `string_view`. Instead, explicitly call the const `.data()` method on the string, which does not reallocate. Fixes: #22090, #23328

* Modernize: Use #pragma once in all header filesKitware Robot2020-09-0325-99/+25
| | | | | | | | | | | | | | | | #pragma once is a widely supported compiler pragma, even though it is not part of the C++ standard. Many of the issues keeping #pragma once from being standardized (distributed filesystems, build farms, hard links, etc.) do not apply to CMake - it is easy to build CMake on a single machine. CMake also does not install any header files which can be consumed by other projects (though cmCPluginAPI.h has been deliberately omitted from this conversion in case anyone is still using it.) Finally, #pragma once has been required to build CMake since at least August 2017 (7f29bbe6 enabled server mode unconditionally, which had been using #pragma once since September 2016 (b13d3e0d)). The fact that we now require C++11 filters out old compilers, and it is unlikely that there is a compiler which supports C++11 but does not support #pragma once.

| | | | | | | | Previously, cm::static_reference_cast used invoke_result_t and took the address of O::get. This is not in complete conformance with standard. This MR changes the implementation to use std::declval<O>.get() which is always well-defined.

* cmstd: Modernize CMake system headersMarc Chevrier2019-09-209-0/+1094
Provide a standardized way to handle the C++ "standard" headers customized to be used with current CMake C++ standard constraints. Offer under directory `cm` headers which can be used as direct replacements of the standard ones. For example: #include <cm/string_view> can be used safely for CMake development in place of the `<string_view>` standard header. Fixes: #19491
