This means that the CLI interface now uses the new key-value oriented
reporter spec, the common reporter base creates the colour implementation
based on the reporter-specific configuration, and it also stores the
custom configuration options for each reporter instance.
Closes#339 as it allows per-reporter forcing of ansi colour codes.
The new reporter spec generalizes key-value options that can be
passed to the reporter, looking like this
`reporterName[::key=value]*`. A key can be either Catch2-recognized,
which currently means either `out` or `colour`, or reporter-specific
which is anything prefixed with `X`, e.g. `Xfoo`.
Test case hashing includes tags and class name
As the hasher involves more code now, it was split out into its own file
and it got its own set of tests.
Closes#2304
This includes always compiling the ANSI and None colour
implementations, as they don't need to touch any platform
specific APIs, and removing their respective compile-time
configuration options.
Because the Win32 colour implementation requires Win32-specific
APIs, it is still hidden behind a compile-time toggle,
`CATCH_CONFIG_COLOUR_WIN32` (renamed from `..._COLOUR_WINDOWS`).
The commandline options for colours were also changed. The
option now uses different name, and allows to select between
different implementations, rather than changing whether
the compiled-in colour implementation is used through
"yes/no/default" options.
Forcing it to be engaged explicitly, either via `op<<`, or by
`ColourGuard::engage`, fixes an issue with multiple `ColourGuard`s
being constructed in a single expression. Because the construction
of the `ColourGuard` instances can happen in arbitrary order,
colours would be applied in arbitrary order too. However, a chain
of `op<<`s has strict call orders, fixing this issue.
FatalConditionHandlerGuard is used within RunContext::invokeActiveTestCase().
The intent of this guard is to avoid binary crash without failed test being
reported.
Still in case FatalConditionHandlerGuard destructor being called during stack
unwinding AND finds unexpected top-level filter for SEH unhandled exception,
the binary may still crash. As result of such crash the original exception
details are being hidden.
As the Catch2 provides only `CATCH_CATCH_ANON` macro, with no access to
exception details by design, looks like the best way to handle issue is to:
- state requirements explicitly by `noexcept` specifier
- use `Catch::cerr()` to print out possible issue notification

* POSIX colour impl is now compiled for all platforms.
* Deciding whether a colour impl should be picked is now stream
dependent, and thus incompatible implementations can be removed
immediately, rather than checking when the colour is being used.
This also required splitting out Listener factory from
the reporter factory hierarchy. In return, the listener
factories only need to take in `IConfig const*`, which
opens up further refactorings down the road in the colour
selection and implementation.
This opens path to per-reporter colour output customization,
and fixes multiple issues with the old colour implementation.
Under the old implementation, using Win32-backed colouring
would always change the colour used by the console, even if the
actual output was written elsewhere, such as a file passed by
the `--out` flag. This will no longer happen, as the reporter's
colour impl will check that the reporter's stream is pointed
to console before trying to change the colours.
POSIX/ANSI colour implementation suffered a similar-ish issue,
in that it only wrote the colour escape codes into the default
output stream, even if the reporter asking for colouring was
actually writing to a completely different output stream.
This will become useful when reworking colour support, because
Win32 colour support requires checking whether the output is
stdout, which is done through the `IStream` wrapper.
The cached handle would become invalid if some other code, say
a user-provided test code, redirects stdout through `freopen`
or `_dup2`, which would then cause AppVerifier to complain.
Fixes#2345
Turns out people are bad at not combining code compiled with GCC
and Clang, and the improvement from `trivial_abi` on `unique_ptr`
is not worth the maintenance cost of having this be an opt-in
change.
Closes#2344
This avoids issues with Catch2's handler firing too early, on
structured exceptions that would be handled later. This issue
meant that the old attempts at structured exception handling
were incompatible with Windows's ASan, because it throws
continuable `C0000005` exception, which it then handles.
With the new handling, Catch2 is only notified if nothing else,
including the debugger, has handled the exception.

This requires a bunch of different changes across the reporter
subsystem.
* We need to handle multiple reporters and their differing
preferences in `ListeningReporter`, e.g. what to do when
we mix reporters that capture and don't capture stdout.
* We need to change how the reporter is given output and
how we parse reporter's output destination from CLI.
* Approval tests need to handle multireporter option
By not materializing the lower cased tags ahead of time, we
save allocations at the cost of worsened performance when comparing
two tags.
Since there are rarely many tags, and commonly they are not
compared even if present, this is almost always a win. The new
implementation also improves the robustness of the code
responsible for handling tags in a case-insensitive manner.
A new flag, `--allow-running-no-tests` was added to override this
behaviour if exit code of 0 was desired.
This change also made `-w NoTests` obsolete, and so it has been
removed.
