Michael Park created MESOS-4549:
-----------------------------------
Summary: Consider returning `Try` for `os::system`.
Key: MESOS-4549
URL: https://issues.apache.org/jira/browse/MESOS-4549
Project: Mesos
Issue Type: Task
Components: stout
Reporter: Michael Park
Priority: Minor
The {{os::system}} has the following description:
{code}
// Executes a command by calling "/bin/sh -c <command>", and returns
// after the command has been completed. Returns 0 if succeeds, and
// return -1 on error (e.g., fork/exec/waitpid failed). This function
// is async signal safe. We return int instead of returning a Try
// because Try involves 'new', which is not async signal safe.
inline int system(const std::string& command);
{code}
Since {{Try}} no longer involves dynamic allocations, we can reconsider
returning a {{Try}} out of this function.
