The macros are now more modular and there they include weak pointer and unique pointer definitions.

On classes which are not copy constructible we cannot make a make_unique definition, so there are two main entry point macros now, RCLCPP_SMART_PTR_DEFINITIONS and RCLCPP_SMART_PTR_DEFINITIONS_NOT_COPYABLE. Where the latter is used on classes which are not copyable. I worked with @esteve to come up with an automatic solution to this using enable_if or something similar, but it doesn't seem to be possible with only one macro inside the class definition. So I made two macros instead. It will not compile if you use the wrong macro, so that should be ok.

These changes were pull out of #73, so I'll rebase that one once this is merged. For review.

CI:

RCLCPP_WEAK_PTR_DEFINITIONS(Class) \
__RCLCPP_UNIQUE_PTR_TYPEDEF(Class)

#define __RCLCPP_SHARED_PTR_TYPEDEF(Class) typedef std::shared_ptr<Class> SharedPtr;

Just an aesthetic suggestion. Given that we're redoing the macros, we can start using using instead of typedef:

#define __RCLCPP_SHARED_PTR_TYPEDEF(Class) using SharedPtr = std::shared_ptr<Class>;

this would make the code more uniform if any of the aliases require a template, since typedef can't be templated.

Ok, I fixed the bug (it was caused by selecting partial diffs to commit out of the previous pr) and I switched to using X = ... rather than typedefs.

New Linux job: http://ci.ros2.org/job/ros2_batch_ci_linux/190/

OS X is still broken for some reason.

Ok, here is the OS X one: http://ci.ros2.org/job/ros2_batch_ci_osx/125/

RCLCPP_WEAK_PTR_DEFINITIONS(Class) \
__RCLCPP_UNIQUE_PTR_TYPEDEF(Class)

#define __RCLCPP_SHARED_PTR_TYPEDEF(Class) using SharedPtr = std::shared_ptr<Class>;

I'd rename name this macro to __RCLCPP_SHARED_PTR_ALIAS (or something similar), given that it's no longer a typedef

* rosbag2_transport package with python interface

* use cpp for python extension

* use rosbag2_transport cpp API

* use rosbag2_transport API in cli

* linters

* ros2GH-25 Rename target librosbag2 to rosbag2

CMake already prepends libraries with `lib`, so the old name resulted
in `liblibrosbag2`

* ros2GH-21 Initial call of rosbag2.record() from rosbag2_transport

* ros2GH-21 Add missing copyright header

* ros2GH-21 Cleanup clang tidy issues

* ros2GH-21 Remove rclcpp dependency from rosbag2

* ros2GH-21 Wire rosbag play into CLI

* ros2GH-21 Add missing test_depend in rosbag2_transport package.xml

* ros2GH-21 Enable -a in CLI, show help on wrong args

* ros2GH-85 Introduce topic and type struct for readability

* ros2GH-85 Do not export sqlite3 as dependency from default plugins

- not referenced in header, therefore unnecessary

* ros2GH-85 Move rosbag2 except typesupport to rosbag2_transport

* ros2GH-85 Add rosbag2 wrapper

* ros2GH-85 Change signature of create_topic to take TopicWithType

* ros2GH-85 Use rosbag2 in rosbag2_transport

- Don't link against rosbag2_storage anymore

* ros2GH-87 Make end-to-end test work on Windows

* ros2GH-87 Fix uncrustify

* ros2GH-87 Refactor end-to-end test fixture

* ros2GH-87 Delete directories recursively on Linux

* ros2GH-87 Reset ROS_DOMAIN_ID to protect against concurrent tests

* ros2GH-89 Make rosbag2 interfaces virtual and add explicit open() method

This allows downstream packages (e.g. rosbag2_transport) to mock these
interfaces in tests.

* ros2GH-87 Improve test and refactoring

* ros2GH-87 Minor refactoring to increase test readability

* ros2GH-87 Fix environmental variable behaviour on Mac

- hide unnecessary methods in typesupport_helpers
- fix incorrect logging in tests
- minor cleanup

* Change name of nodes in rosbag2_transport

* Cleanup folder structure in rosbag2_storage and rosbag2_tests

- use src/<package_name>/ and test/<package_name>/ folders everywhere
