- For the debian/buster docker build (GCC 7/C++17) install and use the
system `catch` package; this also renames "COMPILER_PACKAGES" to
"EXTRA_PACKAGES" since it now contains a non-compiler package.
- Add a status message indicating the catch version being used for
compiling the embedded tests
- Simplify some bash code by using VAR+=" foo" to append (rather than
VAR="${VAR} foo"
- Fix CMAKE_INCLUDE_PATH appending: it was prepending the ':' but not
the existing $CMAKE_INCLUDE_PATH value and so would end up with
":/eigen-path" if CMAKE_INCLUDE_PATH was already set. (This wasn't
bug that was actually noticed since currently nothing else sets it).
When Travis changes their default Python 3.x, it breaks any hardcoded
version selection. Fix: make pyenv activate everything (2.7, 3.x) and
use whichever Python 3.x is on by default.
[skip appveyor]
* Update Python 3 osx image to xcode8.3 to speed up brew install.
The Python 2 osx image remains xcode7.3.
* Have one osx config run in debug mode to improve coverage.
* Only run CMake build tests on two configs to speed up overall build.
The CMake tests take ~30 seconds on each configuration, but we really
only need to them to run on two: one on Linux and one on macOS. This
mirrors the recent change on AppVeyor.
* Merge the style/docs/pip tests with the barebones build.
* Merge 32-bit and CMake install configurations.
This removes clang 3.9 from testing, but there are already 3 other clang
versions being tested on Travis and the new xcode8.3 image should be
close to clang 3.9.

The default `install_headers` from `distutils` flattens all the headers
into a single directory -- `detail` subdirectory was lost. This commit
fixes this by overriding the setup with a custom header installer.
Tests are added to Travis to make sure `setup.py sdist` and `pip install`
do not miss any headers and that the directory structure is preserved.
[skip appveyor]
* Doxygen needs `RECURSIVE = YES` in order to parse the `detail` subdir.
* The `-W` warnings-as-errors option for sphinx doesn't work with the
makefile build. Switched to calling sphinx directly.
* Fix "citation [cppimport] is not referenced" warning.
In C++11 mode, `boost::apply_visitor` requires an explicit `result_type`.
This also adds optional tests for `boost::variant` in C++11/14, if boost
is available. In C++17 mode, `std::variant` is tested instead.
gcc 7 is now in debian testing ("buster"), with a proper stable upstream
release; this updates the associated travis-ci to use "buster" (rather
than "sid"), and removes the build from allow_failures.
Debian stretch was just released, so `debian:testing` and
`debian:stetch` are starting to diverge; this commit keeps the travis-ci
docker image on stretch for gcc6 and clang3.9.
Debian has also moved gcc 7 from experimental to unstable, so this
switches the gcc7 build to `sid`. Once it migrates to `testing` I'll
switch the gcc 7 build docker image to `testing` and take it out of
failure-allowed.
The clang 4.0/cpp17 build wasn't enabling -flto because the system
linker didn't like the output generated by clang for some reason. This
switches the build to use llvm's lld instead, which lets -flto work
again (and links considerably faster, too).
numpy 1.13.0 fails with pypy 5.7.1, so this upgrades to 5.8.0. I've
also uploaded pre-built .whl files to imaginary.ca (checked every 4
hours and rebuilt if needed), and list that as an extra pypi location
under the pypy pip install to avoid the long travis pypy build times for
a new release or branch.
At this point, there is only a single test for interpreter basics.
Apart from embedding itself, having a C++ test framework will also
benefit the C++-side features by allowing them to be tested directly.
The job is using the released clang and stable-branch libc++, which
wasn't the case when it was added. Leave the g++7/c++17 in
allow_failures for now as it's still a pre-release compiler (and pulled
from debian experimental).
Various bash variables that are only used in the travis-ci script and
don't need to propagate (e.g. to cmake) are being pointlessly exported;
this removes these `export`s.
This uses the trusty container rather than docker for the clang 4.0
build. It also caches the local libc++ installation so that it doesn't
need to be compiled every time, which should speed up the job
considerably.
This applies several changes to the non-docker travis-ci builds:
- Make all builds use trusty rather than precise. pybind can't really
build in precise anyway (we install essentially the entire toolchain
backported from trusty on every build), and so this saves needing to
install all the backported packages during the build setup.
- Updated the 3.5 build to 3.6 (via deadsnakes, which didn't backport
3.6 to ubuntu releases earlier than trusty).
- As a result of the switch to trusty, the BAREBONES build now picks up
the (default installed) python 3.5 installation.
- Invoke pip everywhere via $PYTHON -m pip rather than the pip
executable, which saves us having to figure out what the pip
executable is, and ensures that we are using the correct pip.
- Install packages with `pip --user` rather than in a virtualenv.
- Add the local user python package archive to the travis-ci cache
(rather than the pip cache). This saves needing to install packages
during installation (unless there are updates, in which case the
package and the cache are updated).
- Install numpy and scipy on the pypy build. This has to build from
source (and so blas and fortran need to be installed on the build),
but given the above caching, the build will only be slow for the first
build after a new numpy/scipy release. This testing is valuable:
numpy has various behaviour differences under pypy.
- Added set -e/+e around the before_install/install blocks so that a
failure here (e.g. a pip install failure or dependency download
failure) triggers a build failure.
- Update eigen version to latest (3.3.3), mainly to be consistent with
the appveyor build.
- The travis trusty environment has an upgraded cmake, so this
downgrades cmake (to the stock trusty version) on the first couple
jobs so that we're still including some cmake 2.8.12 testing.
Nightlies for pypy no longer run on Ubuntu 12.04; change the pypy build
distribution to the travis-ci trusty (i.e. 14.04) beta container.
The pypy build was also installing numpy and scipy for the *system*
python version, which was pointless; this also adds a guard to the
eigen/numpy/scipy install code with a !PYPY check.
* 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.
Recent gcc snapshots (both gcc 7 snapshots and recent gcc 6 stable
branch snapshots) are triggering an upstream gcc bug when -flto is
enabled (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79296). This has
been hitting the gcc-7 builds for a while now, but is going to start
hitting the debian testing builds in a few days as well.
The issue is triggered by using -flto in combination with structs or
classes declared in a function, as done in test_alias_initialization,
test_isses, test_methods_and_attributes (and possibly more).
I'm subscribed to the upstream bug, and will submit another PR to
reenable LTO once a fixed gcc is available.
The gcc-7 build also generates some warnings; just ignore them for now
(by turning off -Werror).
* Make 'any' the default markup role for Sphinx docs
* Automate generation of reference docs with doxygen and breathe
* Improve reference docs coverage
* Temporarily allows osx homebrew Python 3.6 to fail.
https://github.com/pybind/pybind11/pull/570#issuecomment-269120613
"Homebrew just got Python 3.6 (brew install python3), but numpy and scipy don't have binary wheels for 3.6 yet so it's trying to compile from source and failing."
Add a BUILD_INTERFACE and a pybind11::pybind11 alias for the interface
library to match the installed target.
Add new cmake tests for add_subdirectory and consolidates the
.cpp and .py files needed for the cmake build tests:
Before:
tests
|-- test_installed_module
| |-- CMakeLists.txt
| |-- main.cpp
| \-- test.py
\-- test_installed_target
|-- CMakeLists.txt
|-- main.cpp
\-- test.py
After:
tests
\-- test_cmake_build
|-- installed_module/CMakeLists.txt
|-- installed_target/CMakeLists.txt
|-- subdirectory_module/CMakeLists.txt
|-- subdirectory_target/CMakeLists.txt
|-- main.cpp
\-- test.py
This commit includes modifications that are needed to get pybind11 to work with PyPy. The full test suite compiles and runs except for a last few functions that are commented out (due to problems in PyPy that were reported on the PyPy bugtracker).
Two somewhat intrusive changes were needed to make it possible: two new tags ``py::buffer_protocol()`` and ``py::metaclass()`` must now be specified to the ``class_`` constructor if the class uses the buffer protocol and/or requires a metaclass (e.g. for static properties).
Note that this is only for the PyPy version based on Python 2.7 for now. When the PyPy 3.x has caught up in terms of cpyext compliance, a PyPy 3.x patch will follow.
Current debian testing has Python 2.7.13-RC1, which has a serious
regression (upstream https://bugs.python.org/issue5322) which should be
reverted for RC2 (or the final 2.7.13). Ignore build failures for this
build test temporarily (with the intention of reverting this commit in a
couple of weeks once it stops failing, i.e. when debian testing picks up
an updated python 2.7 release).
Add a build using g++-7 snapshot from debian experimental. This build
is set to allow failures without triggering an overall build failure
(since this is an experimental compiler with experimental support for a
future C++ standard).
A flake8 configuration is included in setup.cfg and the checks are
executed automatically on Travis:
* Ensures a consistent PEP8 code style
* Does basic linting to prevent possible bugs
- Try to update and upgrade twice (with a brief pause between attempts)
to deal with occassional spurious server failures or repository race
conditions. Do the same for the main package install.
- Use dist-upgrade instead of upgrade for updating the image
- Add -q to the upgrade and install commands to make apt less verbose.
This adds a tool that checks style (currently just for tabs instead of
spaces in files under include/tests/docs) and produces a travis-ci build
failure if any problems are found.
Installing something outside the project directory from a cmake
invocation is overly intrusive; this changes tests/CMakeLists.txt to
just fail with an informative message instead, and changes the
travis-ci builds to install pytest via pip or apt-get.
ccache on Travis was never configured properly so the setting never
actually did anything. Enabling ccache for real brings other issues:
due to the way the preprocessor is handled, some of the Python header
macros produce bogus compiler warnings (which in turn produce errors
with -Werror). ccache also requires additional configuration on OS X
and docker. It would reduce compile time by ~30 seconds at best, so
it's not worth the trouble.

This build makes sure everything still works without optional
dependencies (numpy/scipy/eigen) and also tests the automatic
discovery functions in CMake (Python version, C++ standard).
[skip appveyor]
Use simple asserts and pytest's powerful introspection to make testing
simpler. This merges the old .py/.ref file pairs into simple .py files
where the expected values are right next to the code being tested.
This commit does not touch the C++ part of the code and replicates the
Python tests exactly like the old .ref-file-based approach.
Rather than adding an `if [ -n "$DOCS" ]` as a separate install
instruction, this simplifies the travis-ci logic to do the pip/venv
setup in the `before_install` hook, leaving the install hook to just
install the needed packages.
This makes the default install script simpler: it doesn't need to check
NATIVE_DEPS or DOCS because both of those now override `install`
anyway, so the top-level `install` is really just the install for the
gcc-4.8 and osx builds; the docker builds and docs build override
install completely.
