They now take `StringRef` as the argument, and are virtual only
in the basic interface.
Also cleaned out the various reporters and their overrides
of these members which were often empty or delegating up.
This means that e.g. for `TEST_CASE` with two sibling `SECTION`s
the event will fire twice, because the `TEST_CASE` will be entered
twice.
Closes#2107 (the event mentioned there already exists, but this
is its counterpart that we also want to provide to users)
This means that it can no longer be safely made ahead of time,
but nothing in our existing code used it like that. Normally it
is constructed and used in the same expression, which is now
more efficient.
Using the `CATCH_MOVE` and `CATCH_FORWARD` macros instead of the
`std::move` and `std::forward<T>` utility functions can improve
compilation times and debug build's performance, and thus will
be preferred going forward.
With these changes, all these benchmarks
```cpp
BENCHMARK("Empty benchmark") {};
BENCHMARK("Throwing benchmark") {
throw "just a plain literal, bleh";
};
BENCHMARK("Asserting benchmark") {
REQUIRE(1 == 2);
};
BENCHMARK("FAIL'd benchmark") {
FAIL("This benchmark only fails, nothing else");
};
```
report the respective failure and mark the outer `TEST_CASE` as
failed. Previously, the first two would not fail the `TEST_CASE`,
and the latter two would break xml reporter's formatting, because
`benchmarkFailed`, `benchmarkEnded` etc would not be be called
properly in failure cases.
This is a simplification of the fix proposed in #2152, with the
critical function split out so that it can be tested directly,
without having to go through the ULP matcher.
Closes#2152
In v2 it was placed in a very central header due to the way it was
stitched together. Now that we don't do that, we can move it to the
proper place, removing the potential for confusion given that the
original header was split apart and renamed.
- NVHPC's implementation of `__builtin_constant_p` has a bug which
results in calls to the immediately evaluated lambda expressions to be
reported as unevaluated lambdas.

- Hence, we disable CATCH_INTERNAL_IGNORE_BUT_WARN for NVHPC Compilers
This let's us avoid running `strlen` at runtime to convert the
plain string literals to `StringRef`s, by guaranteeing that we
instead have the size available after compilation.
In optimized builds the performance improvement should be even
greater, as the `StringRef` UDL and the related constructor
are both `constexpr`, and thus can be baked completely during
compilation.
Previously, string literals and `std::string`s would match the
template variant, which would serialize them into a stream and then
call the `StringRef` overload for resulting string. This caused
bunch of codebloat and unnecessary pessimization for common usage.
This introduces a potential lifetime risk when using the API, but
the intended way to use the `XmlEncode` class is to use it directly,
e.g. `out << XmlEncode(some-text-argument)`, not to store it around.
The benefit is that we avoid allocations for strings that do not fit
into SSO for given platform.
In some places the `std::flush` was not added, as it was sufficiently
obvious that the flush semantics are not intended. There are likely
other places where the flush semantics aren't intended, but that
is a cleanup for later.
More specifically, made the actual implementation of string-like
type handling take argument as `Catch::StringRef`, instead of
taking `std::string const&`.
This means that string-like types that are not `std::string` no
longer need to pay for an extra construction of `std::string`
(including the potential allocation), before they can be stringified.
The actual string stringification routine is now also better about
reserving sufficient space.
Apart from being clearer, it also improves the overall codesize
of the implementation library, and should improve the performance
as well, by removing one level of indirection.
Because new glibc has changed `MINSIGSTKSZ` to be a syscall instead
of being constant, the signal posix handling needed changes, as it
used the value in constexpr context, for deciding size of an array.
It would be simple to fix it by having the handler determine the
signal handling stack size and allocate the memory every time the
handler is being installed, but that would add another allocation
and a syscall every time a test case is entered.
Instead, I split apart the idea of preparing fatal error handlers,
and engaging them, so that the memory can be allocated only once
and still be guarded by RAII.
Also turns out that Catch2's use of `MINSIGSTKSZ` was wrong, and
we should've been using `SIGSTKSZ` the whole time, which we use now.
Closes#2178
* [Issue 2154] Correct error when building with IBM's latest XLC compiler with xlclang++ front-end.
On AIX, the XLC 16.1.0.1 compiler considers the call to `std::abs` ambigious, so it needs help with a static_cast to the type of the template argument.

Also generalized the implementations to write to the provided
output stream, which will be required for the follow up changes,
where the listings should happen to the location user asked for
by specifying the `-o` flag.
Previously, every base derived from the IStreamingReporter had
its own `IConfig const* m_config` member, so this just centralizes
the handling thereof.
Part of #2061
The old name was a legacy of v2 era, where all headers were stitched
into one. With v3 using separate headers, it is better when they have
proper name.
Previous splitting of catch_common.hpp left it containing only one
actual thing, which is the `SourceLineInfo` type. Given that, there
is no reason to keep the old name.
Also found out that it was included in some places for no reason
(primarily Matchers).
With GCC 10, the `static_cast<bool>` triggers the -Wuseless-cast warning. This commit changes the cast into `static_cast<const bool&>`: it achieves the same thing but doesn't trigger the warning thanks to the "gratuitous" type conversion to `const bool&`. As per references rules, `const bool&` should bind to anything, be it `const` or not, an rvalue or an lvalue, so I doubt that this change is breaking anything.
The problem was that under specific circumstances, namely that none
of their children progressed, `GeneratorTracker` will not progress.
This was changed recently, to allow for code like this, where a
`SECTION` follows a `GENERATE` at the same level:
```cpp
SECTION("A") {}
auto a = GENERATE(1, 2);
SECTION("B") {}
```
However, this interacted badly with `SECTION` filters (`-c foo`),
as they could deactivate all `SECTION`s below a generator, and thus
stop it from progressing forever. This commit makes GeneratorTracker
check whether there are any filters active, and if they are, it checks
whether its section-children can ever run.
Fixes#2025
The new output (mostly) follows the old `--list-test-names-only`
format, with the exception of no longer supporting line output
for `--verbosity high`.
Fixes#2051
The problem was that Catch2 did not reliably include `<exception>`
before it checked for the feature test macro for
`std::uncaught_exceptions`. To avoid overhead of including
`<exception>` everywhere, the configuration check was split out
into a separate header.
Closes#2021
As far as I understand the standard, if there is a function called
`rng` in the global namespace, and a function argument called `rng`,
then the argument should shadow the function. This then means that
uses of `rng` inside the function should refer to the argument.
This is not the case for AppleClang 12.0.0. Luckily the workaround
is simple enough; just rename the argument. Given that the function
is 3 lines and uncomplicated, the change of the name doesn't really
affect readability.
Still, WTF AppleClang?
Closes#2030
At some places, the colour reset code is printed after a newline.
Since the default output buffering to console is line-based, the reset
code is not actually written out. If messages from user code are printed
to stderr (different stream, same console), they are printed before
the colour reset code, and thus they are coloured.
Explicitly flushing the stream after writing the colour escape code solves
this.
Most of the changes are completely pointless renaming of constructor
arguments so that they do not use the same name as the type members,
but 🤷Closes#2015
