--- Fixes ---
* Vector matchers now support initializer list literals better
--- Improvements ---
* Added support for `^` (bitwise xor) to `CHECK` and `REQUIRE`
--- Improvements ---
* Running tests in random order (`--order rand`) has been reworked significantly (#1908)
* Given same seed, all platforms now produce the same order
* Given same seed, the relative order of tests does not change if you select only a subset of them
* Vector matchers support custom allocators (#1909)
* `|` and `&` (bitwise or and bitwise and) are now supported in `CHECK` and `REQUIRE`
* The resulting type must be convertible to `bool`
--- Fixes ---
* Fixed computation of benchmarking column widths in ConsoleReporter (#1885, #1886)
* Suppressed clang-tidy's `cppcoreguidelines-pro-type-vararg` in assertions (#1901)
* It was a false positive trigered by the new warning support workaround
* Fixed bug in test specification parser handling of OR'd patterns using escaping (#1905)
--- Miscellaneous ---
* Worked around IBM XL's codegen bug (#1907)
* It would emit code for _destructors_ of temporaries in an unevaluated context
* Improved detection of stdlib's support for `std::uncaught_exceptions` (#1911)
@ThijsWithaar is responsible for giving me the idea, but his PR
had couple of things that meant it was simpler to rewrite it than
to fix and merge it.
Supersedes and closes#1599
This is because otherwise the installations paths provided via
GNUInstallDirs become messed up and parts of the installation
package will end up in the wrong place.
Also it doesn't make much sense to force dependees to also install
our header alongside them.
Closes#1373
This means
* a new cmake option, `CATCH_BUILD_EXTRA_TESTS`, that conditionally
includes the ExtraTests subfolder
* building and running them on some of the Travis build images
* An example configuration test
In the future these should be extended to cover most of the
configuration options in Catch2, but this is a start.
This also goes for pkg-config installed by our CMake installation.
This includes
* Updating CMake version on Travis
* Adding a `Catch2` subfolder to the `single_include/` folder to
provide this include path both _inside_ the repository, and _outside_.
* Updated examples to build with the new paths
* Other general CMake cleanup
Android apparently does not support `std::to_string`, so we add a
small polyfill over it. Right now only the ULP matcher uses it,
but we have had plans to use it in `StringMaker<int>` and friends,
as it performs a lot better than `std::stringstream` based
stringification on MSVC.
See #1280 for more details
Unlike the relatively non-invasive old way of capturing stdout/stderr,
this new way is also able to capture output from C's stdlib functions
such as `printf`. This is done by redirecting stdout and stderr file
descriptors to a file, and then reading this file back.
This approach has two sizeable drawbacks:
1) Performance, obviously. Previously an installed capture made the
program run faster (as long as it was then discarded), because a call
to `std::cout` did not result in text output to the console. This new
capture method in fact forces disk IO. While it is likely that any
modern OS will keep this file in memory-cache and might never actually
issue the IO to the backing storage, it is still a possibility and
calls to the file system are not free.
2) Nonportability. While POSIX is usually assumed portable, and this
implementation relies only on a very common parts of it, it is no
longer standard C++ (or just plain C) and thus might not be available
on some obscure platforms. Different C libs might also implement the
relevant functions in a less-than-useful ways (e.g. MS's `tmpfile`
generates a temp file inside system folder, so it will not work
without elevated privileges and thus is useless).
These two drawbacks mean that, at least for now, the new capture is
opt-in. To opt-in, `CATCH_CONFIG_EXPERIMENTAL_REDIRECT` needs to be
defined in the implementation file.
Closes#1243
Catch2's documentation promises that listeners are called _before_
reporters, but because of the previous implementation, they were
called _after_ reporters. This commit fixes that.
Closes#1234
