Hello Kudu Jenkins, I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/4648 to look at the new patch set (#10). Change subject: [util] added Subprocess::GetExitStatus() ...................................................................... [util] added Subprocess::GetExitStatus() The Subprocess::GetExitStatus() method allows to retrive exit status and exit information in printable form. That facilitates reporting proper exit status for a sub-processes if using Subprocess::Wait(). The motivation for this change was to free the users of the Subprocess interface of calling WIFEXITED/WEXITSTATUS and friends, duplicating that code over and over. In some cases, callers did not use WEXITSTATUS or WTERMSIG and mistakenly interpreted wait status as sub-process exit status. In short, most users of the Subprocess interface need exit status of a sub-process, not wait status. Also, addressed the race when a signal arrives to the child process before it calls execve(). Todd suggested to use the trick with a pipe and O_CLOEXEC option.
