Independent tests (#665) * Make tests buildable independently This makes "tests" buildable as a separate project that uses find_package(pybind11 CONFIG) when invoked independently. This also moves the WERROR option into tests/CMakeLists.txt, as that's the only place it is used. * Use Eigen 3.3.1's cmake target, if available This changes the eigen finding code to attempt to use Eigen's system-installed Eigen3Config first. In Eigen 3.3.1, it exports a cmake Eigen3::Eigen target to get dependencies from (rather than setting the include path directly). If it fails, we fall back to the trying to load allowing modules (i.e. allowing our tools/FindEigen3.cmake). If we either fallback, or the eigen version is older than 3.3.1 (or , we still set the include directory manually; otherwise, for CONFIG + new Eigen, we get it via the target. This is also needed to allow 'tests' to be built independently, when the find_package(Eigen3) is going to find via the system-installed Eigen3Config.cmake. * Add a install-then-build test, using clang on linux This tests that `make install` to the actual system, followed by a build of the tests (without the main pybind11 repository available) works as expected. To also expand the testing variety a bit, it also builds using clang-3.9 instead of gcc. * Don't try loading Eigen3Config in cmake < 3.0 It could FATAL_ERROR as the newer cmake includes a cmake 3.0 required line. If doing an independent, out-of-tree "tests" build, the regular find_package(Eigen3) is likely to fail with the same error, but I think we can just let that be: if you want a recent Eigen with proper cmake loading support *and* want to do an independent tests build, you'll need at least cmake 3.0.

Add cmake option to override tests (#489) When working on some particular feature, it's nice to be able to disable all the tests except for the one I'm working on; this is currently possible by editing tests/CMakeLists.txt, and commenting out the tests you don't want. This commit goes a step further by letting you give a list of tests you do want when invoking cmake, e.g.: cmake -DPYBIND11_TEST_OVERRIDE="test_issues.cpp;test_pickling.cpp" .. changes the build to build just those two tests (and changes the `pytest` target to invoke just the two associated tests). This persists in the build directory until you disable it again by running cmake with `-DPYBIND11_TEST_OVERRIDE=`. It also adds a message after the pytest output to remind you that it is in effect: Note: not all tests run: -DPYBIND11_TEST_OVERRIDE is in effect

Implement py::init_alias<>() constructors This commit adds support for forcing alias type initialization by defining constructors with `py::init_alias<arg1, arg2>()` instead of `py::init<arg1, arg2>()`. Currently py::init<> only results in Alias initialization if the type is extended in python, or the given arguments can't be used to construct the base type, but can be used to construct the alias. py::init_alias<>, in contrast, always invokes the constructor of the alias type. It looks like this was already the intention of `py::detail::init_alias`, which was forward-declared in 86d825f3302701d81414ddd3d38bcd09433076bc, but was apparently never finished: despite the existance of a .def method accepting it, the `detail::init_alias` class isn't actually defined anywhere. This commit completes the feature (or possibly repurposes it), allowing declaration of classes that will always initialize the trampoline which is (as I argued in #397) sometimes useful.

Allow arbitrary class_ template option ordering The current pybind11::class_<Type, Holder, Trampoline> fixed template ordering results in a requirement to repeat the Holder with its default value (std::unique_ptr<Type>) argument, which is a little bit annoying: it needs to be specified not because we want to override the default, but rather because we need to specify the third argument. This commit removes this limitation by making the class_ template take the type name plus a parameter pack of options. It then extracts the first valid holder type and the first subclass type for holder_type and trampoline type_alias, respectively. (If unfound, both fall back to their current defaults, `std::unique_ptr<type>` and `type`, respectively). If any unmatched template arguments are provided, a static assertion fails. What this means is that you can specify or omit the arguments in any order: py::class_<A, PyA> c1(m, "A"); py::class_<B, PyB, std::shared_ptr<B>> c2(m, "B"); py::class_<C, std::shared_ptr<C>, PyB> c3(m, "C"); It also allows future class attributes (such as base types in the next commit) to be passed as class template types rather than needing to use a py::base<> wrapper.

Make test initialization self-registering Adding or removing tests is a little bit cumbersome currently: the test needs to be added to CMakeLists.txt, the init function needs to be predeclared in pybind11_tests.cpp, then called in the plugin initialization. While this isn't a big deal for tests that are being committed, it's more of a hassle when working on some new feature or test code for which I temporarily only care about building and linking the test being worked on rather than the entire test suite. This commit changes tests to self-register their initialization by having each test initialize a local object (which stores the initialization function in a static variable). This makes changing the set of tests being build easy: one only needs to add or comment out test names in tests/CMakeLists.txt. A couple other minor changes that go along with this: - test_eigen.cpp is now included in the test list, then removed if eigen isn't available. This lets you disable the eigen tests by commenting it out, just like all the other tests, but keeps the build working without eigen eigen isn't available. (Also, if it's commented out, we don't even bother looking for and reporting the building with/without eigen status message). - pytest is now invoked with all the built test names (with .cpp changed to .py) so that it doesn't try to run tests that weren't built.

Overhaul LTO flag detection Clang on linux currently fails to run cmake: $ CC=clang CXX=clang++ cmake .. ... -- Configuring done CMake Error at tools/pybind11Tools.cmake:135 (target_compile_options): Error evaluating generator expression: $<:-flto> Expression did not evaluate to a known generator expression Call Stack (most recent call first): tests/CMakeLists.txt:68 (pybind11_add_module) But investigating this led to various other -flto detection problems; this commit thus overhauls LTO flag detection: - -flto needs to be passed to the linker as well - Also compile with -fno-fat-lto-objects under GCC - Pass the equivalent flags to MSVC - Enable LTO flags for via generator expressions (for non-debug builds only), so that multi-config builds (like on Windows) still work properly. This seems reasonable, however, even on single-config builds (and simplifies the cmake code a bit). - clang's lto linker plugins don't accept '-Os', so replace it with '-O3' when doing a MINSIZEREL build - Enable trying ThinLTO by default for test suite (only affects clang) - Match Clang$ rather than ^Clang$ because, for cmake with 3.0+ policies in effect, the compiler ID will be AppleClang on macOS.

Independent tests (#665) * Make tests buildable independently This makes "tests" buildable as a separate project that uses find_package(pybind11 CONFIG) when invoked independently. This also moves the WERROR option into tests/CMakeLists.txt, as that's the only place it is used. * Use Eigen 3.3.1's cmake target, if available This changes the eigen finding code to attempt to use Eigen's system-installed Eigen3Config first. In Eigen 3.3.1, it exports a cmake Eigen3::Eigen target to get dependencies from (rather than setting the include path directly). If it fails, we fall back to the trying to load allowing modules (i.e. allowing our tools/FindEigen3.cmake). If we either fallback, or the eigen version is older than 3.3.1 (or , we still set the include directory manually; otherwise, for CONFIG + new Eigen, we get it via the target. This is also needed to allow 'tests' to be built independently, when the find_package(Eigen3) is going to find via the system-installed Eigen3Config.cmake. * Add a install-then-build test, using clang on linux This tests that `make install` to the actual system, followed by a build of the tests (without the main pybind11 repository available) works as expected. To also expand the testing variety a bit, it also builds using clang-3.9 instead of gcc. * Don't try loading Eigen3Config in cmake < 3.0 It could FATAL_ERROR as the newer cmake includes a cmake 3.0 required line. If doing an independent, out-of-tree "tests" build, the regular find_package(Eigen3) is likely to fail with the same error, but I think we can just let that be: if you want a recent Eigen with proper cmake loading support *and* want to do an independent tests build, you'll need at least cmake 3.0.

It also allows looking at the travis and appveyor build logs to get an idea of .so/.dll sizes across different build systems. * Minor libsize.py script changes - Use RAII open - Remove unused libsize=-1 - Report change as [+-]xyz bytes = [+-]a.bc%

Add cmake option to override tests (#489) When working on some particular feature, it's nice to be able to disable all the tests except for the one I'm working on; this is currently possible by editing tests/CMakeLists.txt, and commenting out the tests you don't want. This commit goes a step further by letting you give a list of tests you do want when invoking cmake, e.g.: cmake -DPYBIND11_TEST_OVERRIDE="test_issues.cpp;test_pickling.cpp" .. changes the build to build just those two tests (and changes the `pytest` target to invoke just the two associated tests). This persists in the build directory until you disable it again by running cmake with `-DPYBIND11_TEST_OVERRIDE=`. It also adds a message after the pytest output to remind you that it is in effect: Note: not all tests run: -DPYBIND11_TEST_OVERRIDE is in effect
