Problem Report Number 1054 Submitter's Classification Minor System Fault State Resolved Resolution Rejected (REJ) Problem Resolution ID REJ.X.0291 Raised 1970-01-01 08:00 Updated 2003-03-13 08:00 Published null Product Standard Internationalised System Calls and Libraries Extended V2 (UNIX 98) Certification Program The Open Brand certification program Test Suite VSRT version 5.0.1 Test Identification rt.os/procprim/sigwait 2 Problem Summary PG4R.00013 An MSF is requested as the implementation may not select signals in priority order and signals may not be delivered (signal handlers not run) in priority order in a POSIX threads Realtime application Problem Text
This request is for the following test failures:
rt.os/procprim/sigwait/T.sigwait 2
rt.os/rtsignals/sigtimedwait/T.sigtimedwait 5
rt.os/rtsignals/sigwaitinfo/T.sigwaitinfo 5
rt.os/procprim/sigaction/T.sigaction 3
rt.os/procprim/sigaction/T.sigaction 5
The XSH5 specification states that when multiple realtime signals are
pending, sigwait(), sigwaitinfo() and sigtimedwait() shall select the
signal in priority order, with SIGRTMIN having the highest priority
and SIGRTMAX the lowest. The same applies when the realtime signals are
delivered (disposition for realtime signals is to catch, signal handlers
are installed), that is, they shall be delivered in priority order.
We are seeking a MSF for a recognized bug in our implementation whereby
with multiple real time signals pending, the maximum of _POSIX_SIGQUEUE_MAX
(32 for the implementation) instances, sigwait(), sigwaitinfo(), and
sigtimedwait() may not select the signals in priority order and signals
may not be delivered (signal handlers are not run) in priority order in a
POSIX threads Realtime application.
The impact on applications is that they can not depend on the value
_POSIX_SIGQUEUE_MAX. The priority order for selection or delivery of
pending signals is currently supported for a POSIX threads Realtime
application as long as the queue depth is not greater than one.
Priority order is supported when a single instance of any realtime
signal is pending.Test Output
