* Require Git for build tests only if installed GTest is not found
Cloning via Git is not the only path to obtain Google Test framework. In Linux,
using a system package manager is the preferred way, and gtest can be installed
through APK, APT, DNF, pacman, or many other. Now we make Git mandatory after
checking GTest existence.

* Support standalone tests
The patch makes possible to run auto-tests against globally installed GSL,
ignoring local headers. To do this, run CMake in the tests/ folder.
cmake -B build -S tests -DGSL_CXX_STANDARD=14
This feature should not break existing build recipes.

* [cmake] Adding options for INSTALL and TEST (#964)
* [cmake] Adding GSL_INSTALL option
Not all consumers of GSL automatically want to have this install logic.
It's good practice to gate install logic behind an option.
For an example look at magic_enum:
https://github.com/Neargye/magic_enum/blob/master/CMakeLists.txt
If the client wants to install GSL they still can. But they should ask
for it by overriding GSL_INSTALL.
* Update cmake/guidelineSupportLibrary.cmake

* Solve compiler warning C4668: __GNUC__ not defined
* Added c++17 test configurations for clang5.0 and clang6.0
* Removed explicit not_null constructor, sloppy_not_null, added strict_not_null
We added explicit not_null constructor in version 2.0.0.
It proved very difficult to switch to the new version for
large code bases that adopted previous versions of gsl,
due to not_null used extensively in the code. Still, using
explicit constructor is very benefitial for new code, since
it encorages better API design and make null checks intentional.
To resolve the issue, this change:
- removes explicit keyword from not_null constructor
- removes unneded sloppy_not_null type
- adds strict_not_null type to behave the same way as v2 not_null
- updates tests

* fixed build break for gcc7
* added more tests
* added more non-compiling tests
* Addressed PR comments and suppressed a code analysis warning
* Fixed test failure in not_null tests
* Added c++17 test configurations for clang5.0 and clang6.0
* added transition helper sloppy_not_null
* Moved gsl_transition to a samples folder
* Fixed build break and static analysis warnings
* Added c++17 test configurations for clang5.0 and clang6.0
* Fixed CppCoreCheck warnings in GSL and tests
- Added CMakeSettings.json for VS Open Folder configuration
- So we can easily run CppCoreCheck in VS
- Fixed CppCorecheck warnings where it made sense
- Suppressed the rest
- Some suppression does not work due to compiler/tool bugs,
so replaced by #pragma disable
- CppCoreCheck has noise, suppressed those with comments
- Catch produces many warnings, blanket-supressed them all
- Had to fix clang formatting to keep attributes in place
- clang-format does not support attributes, so I am using
- "CommentPragmas: '^ NO-FORMAT:'" to skip formatiting on them
- Removed GSL_NOEXCEPT macro, removed incorred noexcepts
* Ignore unknown attributes
* ignore unknown attributes in noexception mode tests
* fixed C26472 in at()
* created GSL_SUPPRESS macro to allow all compilers to parse suppression attributes
* try to fix gcc compilation problems with attributes
* ignore gsl::suppress for gcc
* move suppression to function level on return statements
clang5.0 and up does not allow attributes on return statemets in constexpr functions
* move suppression to function level on return statements
* use GSL_SUPPRESS in algorithm_tests
* Addressed PR comments
* Added testing with std=c++17 for latest compilers
Added running latest compilers with -std=c++17 option to CI the test matrix,
Updated cmake configuration to allow passing c++ standard on the command line.
* attempt to fix appveyor break
* added clang6.0, removed c++17 tests for clang 5.0
* commented out tests for clang with c++17 die to issue #695
* Addresed comments
* Enable usage of gsl::narrow with exceptions disabled
This solution uses the approach of boost::asio to enabling usage of the
library in environments where exception usage is either prohibited
or not feasible (due to code size constraints). A function template
gsl::throw_exception has been added, which in a normal environment just
throws the exception. However, when GSL_TERMINATE_ON_CONTRACT_VIOLATION
is defined the function is only declared by gsl and the definition of
this function template must be supplied by the library's user.
Closes: #468

Addition:
- understand STL no exception macro
- use function static variable to set termination handler in kernel mode
- add compile-only tests for no-exception mode
* added termination tests and fixed bugs
* disabled warning C4577 for msvc 2015
Catch was being installed to the root of the cmake project. This
violated the source code tree itself and would not work at all if GSL
was being consumed with add_subdirectory.
CMake will now install catch to the build tree under /dependencies.
* Refactor cmake file to have GSL as an interface
CMake supports header only libraries as INTERFACE libraries. Using
interfaces libraries make is easier for users to use the library because
one just need to "link" agaisnt the library and necessary include paths,
definitions, flags... will be taken care of.
This commit creates a new interface library called GSL. It then add the
following things to the GSL library:
- compiler flags ex: (-std=c++14)
- definitions ex: _SCL_SECURE_NO_WARNINGS
- include paths ex: include/gsl
- natvis file
Another project can now have the GSL project as a git submodule and one
only need to add the two following lines to their project to use the
GSL.
add_subdirectory(GSL)
target_link_libraries(<some target> GSL)
After cmake 3.8.0 a lot of the logic can be simplified. Right now the
cmake file has an if for version checking, but when the minimun required
version is 3.8.0 one can just delete the branching and keep the simpler
version.
* Cut support for c++11
Compiling on GCC6.2 with only the c++11 flag will generate compilation
errors. For example some of the errors are related to the use of
enable_if_t which is a c++14 feature.
To avoid compilation errors this comiit removes c++11 support on linux.
* Refactor code that pulls unittest-cpp
Two minor changes:
- uses cmake to find a proper installation of git (in case user does not
have it on the path)
- checks for the CMakeLists file instead. This is needed for the build
itself and seems like a better way to do the checking
* Refactor tests so they show together on VS
This commit will make a VS geenrated project to group all tests under
GSL_tests
* Refactor tests configuration
This creates a test configuration interface and add all the previous
compiler options to that interface. compiler options are now sorted so
it is easier to find them, and also one per line, so that modifications
are easier to track from git.
* Nest "gsl" directory inside a new "include" directory.
* Cleanup the _MSC_VER conditionals a bit; use constexpr on VS2017+.
* Don't #define noexcept on non-Microsoft implementations.
* Workaround VS2017 bug in multi_span. (Also implement == and != for static_bounds_dynamic_range_t because I'm an EoP semantic soundness snob.)
Fixes#441.
When turning on the following flags, several additional warnings
were generated, which have been cleaned up in this patch. The
flags included:
-Wextra
-Wpedantic
-Wconversion
-Wsign-conversion
-Wctor-dtor-privacy
-Wshadow
-Wnon-virtual-dtor
-Wold-style-cast
-Wcast-align
-Woverloaded-virtual
'make install' should install the GSL library (ie. the headers),
not the tests.
It still installs the UnitTest++ headers, but that will be more
complex to fix, as GSL just imports UnitTest++ as a git submodule,
and the install command propagates down to UnitTest++'s
CMakeLists.txt.
* Add test to demonstrate byte aliasing problem on g++ and clang++
* Add note about no-strict-aliasing flag in README
* Activate aliasing unit test and use -fno-strict-aliasing flag
whether using it from the development folder, from the installation
folder or from being copied into a project.
#include <gsl/gsl.h>
Updated headers/tests/instructions/cmake build accordingly
This PR should address https://github.com/Microsoft/GSL/issues/277 (less
the renaming of gsl itself)
