In this example, the IPO/LTO flags should not be added if the
general property is already set for all targets via
`CMAKE_INTERPROCEDURAL_OPTIMIZATION`.
Also, if `CMAKE_INTERPROCEDURAL_OPTIMIZATION` is set to `OFF`, LTO
flags should also not be added. This is sometimes needed when working
around compiler bugs with IPO/LTO, e.g. on ppc64le with some
toolchains.
* Crash when printing Unicode to redirected cout
Add failing tests
* Fix Unicode crashes redirected cout
* pythonbuf::utf8_remainder check end iterator
* Remove trailing whitespace and formatting iostream
* Avoid buffer overflow if ostream redirect races
This doesn't solve the actual race, but at least it now has a much lower
probability of reading past the end of the buffer even when data races
do occur.
When the user defines _GLIBCXX_USE_CXX11_ABI=0 to force the pre-c++11 ABI, numpy.h assumes that is_trivially_copyable is available.
It is not necessarily the case. This patch uses clang's feature detection instead.
The workaround is for certain libstdc++ versions, so the test should target these particular versions.
* Adding PyGILState_Check() in object_api<>::operator().
* Enabling PyGILState_Check() for Python >= 3.6 only.
Possibly, this explains why PyGILState_Check() cannot safely be used with Python 3.4 and 3.5:

* Adding simple micro benchmark.
* Reducing test time to minimum (purely for coverage, not for accurate results).
* Fixing silly oversight.
* Minor code organization improvement in test.
* Adding example runtimes.
* Removing capsys (just run with `-k test_callback_num_times -s` and using `.format()`.
* Use correct duration representation when casting from datetime.timdelta to std::chrono::duration
* When asserting datetime/timedelta/date/time we can equality-compare whole objects
* [dtype]: add type() method to access type attribute of PyArray_Descr (eq. to dtype.char in Python)
* [dtype] change type() name method to char_() to be compliant with Python numpy interface
* [dtype] fix by pre-commit
* [dtype] Change comments and solutions format for test
* Clarify documentation and move note about dtype.char vs PyArray_Descr::type to a plain, non-doxygen comment
* Fix and extend tests
* Fix the supposedly fixed tests
* Fix the fixed tests again

* Adding move_only_holder_caster `typename SFINAE = void` to enable external specializations.
* Adding SFINAE hook also to copyable_holder_caster, for uniformity, with comment to explain the purpose.
* When determining if a shared_ptr already exists, use a test on the weak_ptr instead of a try/catch block.
* When determining if a shared_ptr already exists, use a test on the weak_ptr instead of a try/catch block.
