The Core Guidelines state "A base class destructor should be either
public and virtual, or protected and non-virtual" so, hopefully, no
static analyser will complain.
INTERFACE should be used on dependencies from other than our source files.
PRIVATE should be used the include happens in our source files.
In this case (src/catch2/internal/catch_debug_console.cpp:20) the include
is from our source file.
I encountered a issue with this when building Catch2 for Android in
combination with BUILD_SHARED_LIBS. Changing the visibility to PRIVATE
fixes the issue.
* Removed Conan1 build.py file using conan package tools that are no longer supported
* Working conan 1 and 2 build with the test package.
updated the test_package to be updated to conan 2 and fixed missing cmake. Still need to check that the license file is packaged up and that the packages look identical before the changes
* Removing debug prints and the license check that isn't working yet
* Working license file copied over as it was before
* Migrated the properties of cpp_info to conan 2. Keeping conan 1 support by checking the version of conan
https://docs.conan.io/1/migrating_to_2.0/properties.html
* Revert "Removed Conan1 build.py file using conan package tools that are no longer supported"
This reverts commit a606d1dfe6.
* Need to add a set_version to parse the version from CMakeLists.txt
Adding a package build yaml to ensure conan keeps building on 1 and 2
* Setting lowercase catch2 for pkg_config and cmake_target_name
* Fixing the namespace for conan file cmake_target_name
This was originally motivated by `REQUIRE((a <=> b) == 0)` no
longer compiling using MSVC. After some investigation, I found
that they changed their implementation of the zero literal
detector from the previous pointer-constructor with deleted
other constructors, into one that uses `consteval` constructor
from int.
This breaks the previous detection logic, because now
`is_foo_comparable<std::strong_ordering, int>` is true, but
actually trying to compare them is a compile-time error...
The solution was to make the decomposition `constexpr` and rely
on a late C++20 DR that makes it so that `consteval` propagates
up through the callstack of `constexpr` functions, until it either
runs out of `constexpr` functions, or succeeds.
However, the default handling of types in decomposition is to
take a reference to them. This reference never becomes dangling,
but because the constexpr evaluation engine cannot prove this,
decomposition paths taking references to objects cannot be
actually evaluated at compilation time. Thankfully we already
did have a value-oriented decomposition path for arithmetic types
(as these are common linkage-less types), so we could just
explicitly spell out the `std::foo_ordering` types as also being
supposed to be decomposed by-value.
Two more fun facts about these changes
1) The original motivation of the MSVC change was to avoid
trigering a `Wzero-as-null-pointer-constant` warning. I still
do not believe this was a good decision.
2) Current latest version of MSVC does not actually implement the
aforementioned C++20 DR, so even with this commit, MSVC cannot
compile `REQUIRE((a <=> b) == 0)`.
They can't compile the new constexpr decomposer because
`ITransientExpression` has a defaulted virtual destructor. We could
instead drop the virtual destructor - it only exists to silence
static analysis tools complaining about having virtual functions
without virtual destructor - but GCC 5 and 6 are positively ancient,
so we drop them instead.
Without SSE2 enabled, x86 targets will use x87 FPU, which breaks
the tests checking for reproducible results from our random
floating point number generators. The output is still reproducible,
at least between binaries targetting x87, but the tests hardcode
results for the whole pipeline being done in 32/64bit precision.
Closes#2796
This triggers when running clang-tidy's bugprone-* family of checks
in code which uses Catch2 even if Catch2 headers are marked as
SYSTEM headers due to how code expanded from macros is treated as
first party even if the macro comes from a 3rd party library. The
fix is luckily pretty straightforward.
This check is added in clang-tidy-18 due for release later this year.
Classes will automatically inherit the virtual-ness of their base
class destructors. If the base class already has a virtual
destructor and the derived class needs default destructor semantics
then the derived class can omit defining the destructor in favor of
the compiler automatically defining it.
This has an additional benefit of reenabling move semantics. The
presence of a user-specified destructor automatically disables move
operations.
This is the recommended way of adding new Opts in our documentation
for using custom main, but we did not compile the code to see if it
works. We now compile the example as part of the BUILD_EXAMPLES
option.
Fixes#2787
