Review request for mesos and Jie Yu. Bugs: MESOS-7973 https://issues.apache.org/jira/browse/MESOS-7973 Repository: mesos Description ------- The process is used to "recover" a non-leading VOTING replica by running the recovery protocol to find current begin and end positions of the log and catching-up positions that are missing on the replica. This allows following replicas to serve eventually consistent reads. Diffs ----- src/log/recover.hpp 94d6bb283ea82df607fcc72de05cda3b12ad5d2d src/log/recover.cpp b366818767adb259ee6805f9978fd330b790a264 src/tests/log_tests.cpp f9f9400c901152779ae0ebfe74cf8f7aac1d3396 Diff: https://reviews.apache.org/r/62286/diff/1/ Testing ------- Added tests that verify that the new recovery process correctly performs and produces meaningful result under various circumstances (recovered positions were truncated, replica was lagging far behind). Ran `make check`. Thanks, Ilya Pronin
