[jira] Updated: (HARMONY-6531) [classlib][luni]
URLConnection.getInputStream() does not throw IOException when the socket
is closed
[ https://issues.apache.org/jira/browse/HARMONY-6531?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Catherine Hope updated HARMONY-6531:
------------------------------------
Attachment: 6531.patch
Fix throws a SocketException if end of stream is reached when getting a server response after requesting an input stream. The exception is cached so that subsequent calls to getInputStream (and also getContent) will wrap the original exception. This is in-line with the RI behaviour.
Regression testcase included.

> Calling URLConnection.getInputStream when the socket has been closed returns an input stream that gives -1 when read from. The RI throws an IOException in this situation:
> DisconnectHttpServer server = new DisconnectHttpServer();
> URLConnection conn = (new URL("http://localhost:" + server.server.getLocalPort())).openConnection();
> server.start();
> conn.connect() // this will be successful, but the sockets will be closed immediately after the connection
> conn.getInputStream();
> class DisconnectHttpServer extends Thread {
> ServerSocket server = new ServerSocket();
> DisconnectHttpServer() throws IOException {
> server.bind(new InetSocketAddress(InetAddress.getByName("localhost"), 0));
> }
> public void run() {
> try {
> Socket s = server.accept();
> server.close();
> s.close();
> } catch (Exception e) {
> e.printStackTrace();
> }
> }
> }
> The stack from the RI is:
> java.net.ConnectException: Connection refused
> at java.net.PlainSocketImpl.socketConnect(Native Method)
> at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333)
> at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:195)
> at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:182)
> at java.net.Socket.connect(Socket.java:520)

> at sun.net.www.http.HttpClient.parseHTTP(HttpClient.java:626)
> at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:974)
> But I'm not sure if we should be attempting a reconnect if end of stream is reached, so I've just fixed it by throwing a SocketException that the socket has been closed.
