Expected failures:

• CMake Warnings from Cmake warning about unused variable SECURITY #79 have returned but are not ubiquitous pass --no-warn-unused-cli to CMake to avoid unwanted warnings ci#166 is a proposed solution.

New flakiness:

• composition test flakiness increase (to be investigated) Composition test flakiness increase #118

Long-running flakiness:

• service/parameter tests with fastrtps (common, shows as test failures or timeouts)
• service/parameter tests with connext (less common, shows as a timeout) wait_for_service not being woken by graph events rmw_connext#280
• muiltithreaded tests hanging with connext Flaky: multithreaded comms tests hanging with connext on osx #103
• pendulum_teleop hanging (only runs on connext, linux) Pendulum teleop timeout [connext, linux] #94
  • should be less flaky after Pendulum teleop flakiness reduction demos#232
• hanging tests with fastrtps Various tests hanging sometimes on linux with fastrtps #98
  • TestFindWeakNodes, test_time_source, test_spin
• DomainParticipantFactory_impl::create_participant():!create failure creating participant failures on connext (seems can happen in any test): Connext: Automatic participant index failed to initialize #93
  • We should keep investigating/pushing on them for what is causing this now
• test_utilities access violation: Access violation in new test_utilities test rclcpp#458
• "performance" tests (action pending discussion in Test of node->now() flaky on OS X rclcpp#457)
  • e.g. rclcpp.TestNode.now, timer/waitset testing
• projectroot.test_dynamic_bridge__rmw_fastrtps_cpp / ros1_bridge.test_dynamic_bridge__rmw_fastrtps_cpp.xunit.missing_result (flaky due to fastrtps discovery issues)

Build farmer tasks

• Update Java to 1.8u162 on all hosts (including master): @nuclearsandwich
• Renew https certificate on ci.ros2.org: @nuclearsandwich
• Periodic upgrades on Mac and Windows: Build farmer
• Profile memory usage of bridge compilation job building the bridge requires a lot of memory #106 (failures currently resolved by increasing instance size)
