Summary0001336: getrusage should recursively include information about children of children
DescriptionThe specification for getrusage says that for RUSAGE_CHILDREN information about waited-for
children of the current process is returned. However existing implementations also recursively
include children of children.

In XBD 3.93 Child Process is defined as
A new process created (by fork( ), posix_spawn( ), or posix_spawnp( )) by a given process. A child
process remains the child of the creating process as long as both processes continue to exist.
which makes clear that children of children are not considered children of the current process.
Desired ActionOn page 1089 lines 36960-36962 section getrusage, change
If the
value of the who argument is RUSAGE_CHILDREN, information shall be returned about
resources used by the terminated and waited-for children of the current process.
to
If the
value of the who argument is RUSAGE_CHILDREN, information shall be returned about
resources used by the terminated and waited-for children of the current process and
recursively the terminated and waited-for children thereof.

Interpretation response
------------------------
The standard states that getrusage() with RUSAGE_CHILDREN only reports on direct children, and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor.

Rationale:
-------------
No known implementation has ever worked this way.

Notes to the Editor (not part of this interpretation):
-------------------------------------------------------

On page 1089 lines 36960-36962 section getrusage, change
If the value of the who argument is RUSAGE_CHILDREN, information shall be returned about resources used by the terminated and waited-for children of the current process.
to:
If the value of the who argument is RUSAGE_CHILDREN, information shall be returned about resources used by the children of the current process that have terminated and been waited-for and their children that have terminated and been waited-for, recursively.
