(Updated Feb. 23, 2016, 7:43 p.m.) Review request for mesos, Joris Van Remoortere and Michael Park. Changes ------- Updated to take into account Bernd's review. Note that the patch as it is doesn't completely remove all races, so more thought needs to be put into it. Bugs: MESOS-3271 and MESOS-4711 https://issues.apache.org/jira/browse/MESOS-3271 https://issues.apache.org/jira/browse/MESOS-4711 Repository: mesos Description ------- Under certains circumstances, the future returned by poll is discarded right after the event is triggered, this causes the event callback to be called before the discard callback which results in an abort signal being raised by the libevent library. Diffs (updated) ----- 3rdparty/libprocess/src/libevent_poll.cpp 461624ca003e97be5ea9cf956d86fc294e6f1bc1 Diff: https://reviews.apache.org/r/43799/diff/ Testing ------- ```bash # On CentOS 6.7 running in virtualbox ../configure --enable-ssl --enable-libevent make -j4 check sudo ./bin/mesos-tests.sh --gtest_filter="MemoryPressureMesosTest.CGROUPS_ROOT_SlaveRecovery" --gtest_repeat=1000 ``` Thanks, Alexander Rojas
