Subject [jira] Updated: (HARMONY-6364) [classlib][luni]Set port reuse option not supported which leads to bind reuse address failure
Date Wed, 28 Oct 2009 06:44:59 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-6364?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ray Chen updated HARMONY-6364:
------------------------------

    Description: 
Hi all,

org.apache.harmony.luni.tests.java.net.DatagramSocketTest.test_setReuseAddressZ failed on
z/OS.

Failed at line 1616 when excute the statement "theSocket2.bind(theAddress);"

In native code the bind() function got a EADDRINUSE error.

After looking into the problem, I found that in the fucntion setReuseAddrAndReusePort() of
modules\luni\src\main\native\luni\shared\socket.c does NOT throw a exception if the REUSEPORT
option is NOT supported.
It works well on windows and linux, but seems not well on z/OS, the whole situation can be
summarized in following matrix:

|         |            REUSEPORT     |    bind()
z/OS        |     not supported     |    failed
windows  |     not supported    |    success
linux         |    supported           |    success

Should it throw an exception if REUSEPORT not supported on z/OS?
Any comments?
