Backport Catch2 3.16.1

2026-10-10T23:56:25+00:00

Review Catch2 devel through 08092139210881f01a34e60c5f2fd6afa0ea4024,
the commit of 3.16.1, and apply the eleven changes since the last
reviewed revision in upstream order:

  d7683484  better message when a reporter cannot be initialized
  ea5020f0  custom argument validation in every first-party reporter
  aa01559e  throwing-reporter test also throws in assertionEnded
  45cd3987  noexcept on handleUnexpectedInflightException
  6adbd539  MSVC optimizations enabled again after the benchmark headers
  e87f2882  no quadratic scaling for NTTP test registration
  73d546cd  REQUIRE expands its arguments fewer times under GCC and Clang
  b710039a  decomposer operators as plain functions
  f899467b  type-erased streaming of reconstructed expressions
  8f0e70ca  retired macos-14 runner dropped
  08092139  version 3.16.1 and its release notes

All of them applied to the sources without a conflict. The amalgamated
distribution under extras/ conflicted because it is generated; it is
generated again from the sources of this repository, which also brings
it up to date with fork changes it had not picked up: the list-based
stream pool, the Clang diagnostic boundary and the cassert include.

No file under src/Progmasoft changes. The fork-owned texts that name
the engine version say 3.16.1, and docs/upstream-status.md records the
review. Upstream files keep their names, licenses and compiler options.

Built with Clang 22 on Windows and tested: 148 of 149 tests pass. The
one that fails, Reporters::CrashInJunitReporter, fails the same way on
devel without this change with that compiler.

Let reporters opt into fast path in RunContext::assertionStarting

2025-07-17T11:47:44+00:00

The fast path allows `RunContext` to skip disabling output redirect,
and notifying the reporters, turning `RunContext::notifyAssertionStarted`
into a no-op. This improves the overall performance of assertion handling
significantly, and also prepares ground for future changes around
assertion handling and thread safety.

For simple 10M assertion run, this improves the running time by ~30%
in Debug build and ~40% in Release build.

For backwards-compatibility reasons, the fast path is disabled
by default. However, none of the first party reporters use the
`assertionStarting` event, so all first party reporters are opted-in.

Remove empty implementations of assertionStarting from reporters

2025-07-17T10:47:46+00:00

Add stream flushes after reporters print out the test run metadata.

2025-07-10T21:51:31+00:00

This ensures that the test run metadata are printed even if the
process dies right after.

reporters: silence -Wsubobject-linkage

2024-01-15T08:57:30+00:00

gcc emits `Wsubobject-linkage`, because the the publicly visible
`TablePrinter` contains `ColumnInfo`, which is part of an anonymous
namespace

Move-enable various parts of TextFlow

2023-12-27T20:43:49+00:00

This removes about 200 pointless copies from printing the help
message (the original motivation for the change), and also nicely
improves performance of the various reporters that depend on
TextFlow.

Change 'estimated' to 'est run time' in console reporter output

Flush stream after benchmarkStarting in ConsoleReporter

2023-08-13T21:09:02+00:00

This means that the user will see the estimation of full benchmark
running time when it is available, unlike now when it often only
ends up flushed after the benchmark is fully finished.

This means that the user will almost immediately see the start
of table like this

```
benchmark name                       samples       iterations    estimated
                                     mean          low mean      high mean
                                     std dev       low std dev   high std dev
-------------------------------------------------------------------------------
Fill vector generated                          100            54     3.0834 ms
```

This presents significant improvement in user experience especially
for long running benchmarks.
