(Updated Jan. 27, 2016, 3:20 p.m.)
Review request for mesos, Benjamin Hindman and Artem Harutyunyan.
Changes
-------
Changed to a different approach, putting all the code change into the module.
Bugs: MESOS-4535
https://issues.apache.org/jira/browse/MESOS-4535
Repository: mesos
Description (updated)
-------
Changes the logrotate container logger to manually construct and deal with
pipes. Specifically, both read and write ends of the pipe must end up in the
child processes (read -> logger executables, write -> container).
If ownership is not transferred, the pipe's FDs may be closed (again) when
`Subprocess` is destructed, which may unexpectedly close random FDs belonging
to other threads.
Diffs (updated)

Testing (updated)
-------
make check (OSX)

NOTE: I'll add an integration to codify the manual testing below.
This discarded review has the gist of the needed test:

Manual testing:
```
./mesos-master.sh --work_dir=/tmp/master --ip=127.0.0.1
./mesos-slave.sh --master=127.0.0.1:5050
--modules=file:///path/to/modules.json
--container_logger="org_apache_mesos_LogrotateContainerLogger"
--work_dir=/tmp/agent
# Repeatedly trigger executor terminations.
./mesos-execute --master=127.0.0.1:5050 --name="Repeater" --command="while
true; do /Users/josephwu/mesos/build/src/mesos-execute --master=127.0.0.1:5050
--name=Repeat --command=\"echo Wheee; sleep 0.4\"; done"
```
"modules.json" follows the template:
```
{
"libraries": [
{
"file": "/path/to/liblogrotate_container_logger.la",
"modules": [
{
"name": "org_apache_mesos_LogrotateContainerLogger",
"parameters": [
{
"key": "launcher_dir",
"value": "/path/to/mesos/build/src/"
}, {
"key": "logrotate_stdout_options",
"value": "rotate 2"
}, {
"key": "logrotate_stderr_options",
"value": "rotate 2"
}
]
}
]
}
]
}
```
Thanks,
