-----------------------------------
Summary: Introduce an os::rename abstraction to stout.
Key: MESOS-2265
URL: https://issues.apache.org/jira/browse/MESOS-2265
Project: Mesos
Issue Type: Technical task
Components: stout
Reporter: Michael Park
Assignee: Michael Park
Fix For: 0.22.0
We introduce an {{os::rename}} abstraction to {{stout}} in order to support
atomicity and validity of checkpointed files. Writing directly to the
checkpoint file can leave the file in a corrupted state if either: the slave
crashes while writing, or checkpointing encounters an error and the slave
crashes before the partially written file is removed. We should checkpoint to a
temporary file instead and use {{os::rename}} to atomically move it to the
desired path.
