    Problem Summary TSD4U.00311 The tests do not allow sufficient time for the syslog message to appear in the log file
    Problem Text

    There is a timing issue with both of these assertions.

    Both contain the following code:

    tet_infoline("PREP: Send message using syslog");
    syslog(LOG_DEBUG,TESTSTRING);

    ret = stat(test_fileptr,&statbuf);
    if(ret){
    uwerrno("stat");
    return;
    }


    tet_infoline("PREP: Wait for syslog output");
    while(statbuf.st_mtime == oldstat.st_mtime && count < 10){
    ret = stat(test_fileptr,&statbuf);
    if(ret){
    uwerrno("stat");
    return;
    }
    count++;
    ret=sleep(1);
    if(ret){
    uwerrno("sleep");
    return;
    }
    }

    if(statbuf.st_mtime == oldstat.st_mtime){
    tet_infoline("ERROR: syslog() failed to send message to logging
    facility");
    tet_result(TET_UNRESOLVED);
    return;
    }

    The problem here is that the loop is so fast, it does not give syslog() enough
    time to write the message.

    By increasing 10 to 30 in the while condition, the tests will pass.

    /tset/CAPI.os/genuts/openlog/T.openlog 2 Unresolved

    Test Description:
    Base Required Conformance
    A call to void openlog(const char *ident, int logopt, int facility)

    Test Description:
    Base Required Conformance
    A call to void openlog(const char *ident, int logopt, int facility)
    when LOG_PID is set in logopt shall cause subsequent calls to syslog()
    to log the process ID with each message.

    Test Information:

    PREP: Start logging facility
    PREP: Close log to start

    Review Recommendation No Resolution Given
    Review Response
    The openlog() tests do not allow as much time for the message to appear in
    the log file as the tests for syslog() itself (in CAPI.os/genuts/syslog),
    so it would seem appropriate to change them to be consistent with the
    syslog() tests. This is not as great an increase as requested by the
    submitter (it would double the time allowed rather than trebling it),
    however it is assumed that if some of the syslog() tests were failing for
    the same reason, they would have been included in this request, and
    therefore the time allowed by the syslog() tests is sufficient.

    It is recommended that a TSD is granted.

    Review Conclusion
    This is an agreed Test Suite Deficiency.
