Hi, I no longer support the demo because in 4.0 I changed the framework quite a bit. The reason it was changed was to support NIO. The result is a vastly more scalable server that can out perform just about every other server of this type. Another reason I stopped supporting it was because much of my time was spent on developing an MVC framework, when the focus should really be the core server itself. I would recommend using Simple as the server, and using either Velocity or Freemarker on its own. There is plenty of documentation on Velocity and Freemarker on their own sites. As an alternative, you can use Restlet[1] or Jersey[2] (release 1.0.3 will contain a Simple container shortly, 1.0.3-SNAPSHOT currently supports Simple). They are very lightweight, in particular Restlet is very light an contains modules you can pick and choose. It has a very low footprint and plenty of documentation.

I was searching for a lightweight java web server and the only one i found was simpleweb. In fact Jetty and Tomcat are really too heavy for an "embedded" project. I try the demo and without any documentation i had a hard time but now I think it's ok. I was thinking of writing some "Quick start doc" but this project does not exists in the 4 version of simpleweb. So my question is : Do you plan to continue this "demo" project ? Which in fact looks like your mamba project (stopped in 2003) Thanks Laurent Lauden |

Hi,
Thanks for the feedback, in particular the stack trace is interesting "java.net.SocketException: Transport endpoint is not connected". This looks like the client has shutdown the connection before the server has. I think your suggestion of a try catch makes sense here, however I do not think the socket will be left in an open state resulting in a leak.
For the transport cursor error you report, this is fine. This happens with tools like apache bench, or other clients that choose to close the input before they fully read the response. It will have no effect on the processing of the request.
Thanks,
Niall

Subject: Re: [Simpleweb-Support] simple-4.1.10 is leaking file handles
I think I have found something.
First my environment:
- rehel5
- java version "1.6.0_13"
I have just added exception.printStackTrace() where exceptions were ignored or silently processed.
The I got this exception:
java.net.SocketException: Transport endpoint is not connected
at sun.nio.ch.SocketChannelImpl.shutdown(Native Method)
at
sun.nio.ch.SocketChannelImpl.shutdownOutput(SocketChannelImpl.java:651)
at sun.nio.ch.SocketAdaptor.shutdownOutput(SocketAdaptor.java:368)
at
org.simpleframework.transport.SocketWriter.close(SocketWriter.java:185)
at
org.simpleframework.transport.SocketController.close(SocketController.java:1
01)
at
org.simpleframework.transport.SocketTransport.close(SocketTransport.java:241
)
at
org.simpleframework.http.core.TransportCursor.close(TransportCursor.java:238
)
So I simply surrounded this call with a try catch:
public synchronized void close() throws IOException {
if(!closed) {
closed = true;
builder.close();
try {
channel.socket().shutdownOutput(); // send FIN ACK
} catch (IOException ioex) {
}
channel.close();
}
}
I still got an Exception but it looks it does nothing wrong:
java.io.IOException: Connection reset by peer
at sun.nio.ch.FileDispatcher.read0(Native Method)
at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:21)
at sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:233)
at sun.nio.ch.IOUtil.read(IOUtil.java:206)

at
org.simpleframework.http.core.TransportCursor.ready(TransportCursor.java:177
)
at
org.simpleframework.http.core.TransportCursor.isReady(TransportCursor.java:1
14)
I think there is a typo in BufferAllocator.getInputStream()
public InputStream getInputStream() throws IOException {
if (buffer == null) {
//if(buffer != null) { <--- HERE
allocate();
}
return buffer.getInputStream();
}

I think I have found something.
First my environment:
- rehel5
- java version "1.6.0_13"
I have just added exception.printStackTrace() where exceptions were ignored
or silently processed.
The I got this exception:
java.net.SocketException: Transport endpoint is not connected
at sun.nio.ch.SocketChannelImpl.shutdown(Native Method)
at
sun.nio.ch.SocketChannelImpl.shutdownOutput(SocketChannelImpl.java:651)
at sun.nio.ch.SocketAdaptor.shutdownOutput(SocketAdaptor.java:368)
at
org.simpleframework.transport.SocketWriter.close(SocketWriter.java:185)
at
org.simpleframework.transport.SocketController.close(SocketController.java:1
01)
at
org.simpleframework.transport.SocketTransport.close(SocketTransport.java:241
)
at
org.simpleframework.http.core.TransportCursor.close(TransportCursor.java:238
)
So I simply surrounded this call with a try catch:
public synchronized void close() throws IOException {
if(!closed) {
closed = true;
builder.close();
try {
channel.socket().shutdownOutput(); // send FIN ACK
} catch (IOException ioex) {
}
channel.close();
}
}
I still got an Exception but it looks it does nothing wrong:
java.io.IOException: Connection reset by peer
at sun.nio.ch.FileDispatcher.read0(Native Method)
at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:21)
at sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:233)
at sun.nio.ch.IOUtil.read(IOUtil.java:206)
at sun.nio.ch.SocketChannelImpl.read(SocketChannelImpl.java:236)
at
org.simpleframework.transport.SocketTransport.read(SocketTransport.java:184)
at
org.simpleframework.http.core.TransportCursor.peek(TransportCursor.java:195)
at
org.simpleframework.http.core.TransportCursor.ready(TransportCursor.java:177
)
at
org.simpleframework.http.core.TransportCursor.isReady(TransportCursor.java:1
14)
I think there is a typo in BufferAllocator.getInputStream()
public InputStream getInputStream() throws IOException {
if (buffer == null) {
//if(buffer != null) { <--- HERE
allocate();
}
return buffer.getInputStream();
}

Hi, If you do not pipe lsof through wc -l you will see the file handles point to libraries loaded by the JVM. These are not open sockets. I ran your test on Mac OS X and it stops at 58. These are the various shared libraries. It will not grow or leak. Thanks for the feedback though, its appreciated.

I don't see any problem when watching netstat but lsof reports ever growing number of file handles. I have attached a small example java -cp bin:lib/simple-4.1.9.jar org.simpleframework.ServerTest will launch the server on port 900 java -cp bin org.simpleframework.ClientTest <host> will run a client initially for the server, I have: >lsof -p 3040 | wc -l 42 Then each time I run the client test >lsof -p 3040 | wc -l 49 next >lsof -p 3040 | wc -l 55 And so on. It doesn't look like a connection problem. > -----Original Message----- > From: Niall Gallagher [mailto:gal...@ya...] > Sent: Friday, April 03, 2009 2:16 PM > To: Simple support and user issues > Subject: Re: [Simpleweb-Support] simple-4.1.10 is leaking file handles > > > Hi, > > I really don't think there is a file leak here.

Hi, I really don't think there is a file leak here. I have just performed 10,000,000 requests with apache bench using HTTP/1.0 (non persistent) connections. and 100,000,000 persistent connections with apache bench. Everything was fine. On both Linux and Windows. I think you are either not closing the connection or not expecting "Transfer-Encoding: chunked" responses which will be maintained. Such connections should be closed from the client side. Also, Simple will close all dormant connections after two minutes. Regardless, so all resources will be cleaned up eventually. If you can prove me wrong, by means of a unit test. I would be very grateful. However, I really doubt there is a connection leak. In particular the changes between 4.1.9 and 4.1.10 do not really deal with connections.

Hi, Can you try "netstat -P tcp" to get the actual TCP settings, perhaps grep for the server port to match the connections. I have just run a test with a couple of thousand connections and it worked fine. However, I am not doubting there is a problem. Also I have just introduced a new test to 4.1.10 that uses the java.net.URL (which delegates to java.net.HttpUrlConnection) and it runs through a couple of hundred connectiosn per sec without issue. I'll run some more substantial tests shortly. I would really need to see the TCP state of the leaking connections to know what is happening.

Hi, What is connecting to the server, are you using a load tester such as ApacheBench. Also, are you closing the connections? For example Response.close(); Or OutputStream.close(); Within the resource or container. Just looking at the code for the change and it does not seem likely that a file leak could occur, but I'd like to know exactly what you see. If you could I would appreciate any information on the TCP state of the connections. Are they CLOSE_WAIT, TIME_WAIT or something like FIN_WAIT1?

Hi, Streaming was broken recently. I have fixed the issue and 4.1.10 has been released with a fix for streaming. 4.1.10 should be available for download shortly.

Hi, Yes you should be able to stream the response. There have been changes recently but streaming should still be fully supported. I'll run a couple of tests and let you know. If streaming is broken ill release an update with a fix.

Is it possible to stream a response? The Response documentation says "A buffer size can be specified when acquiring the output stream which allows data to be buffered until it over flows or is flushed explicitly" I tried setting the "Transfer-Encoding" header to "chunked" and flushing the output stream at the end of each "chunk", but it didn't seem to do anything, the client didn't receive any chunks until the whole response was complete. Doing this works in Jetty, for example. Am I just missing something, or is this just not possible? Nice project, btw. I'm just using it as a basic webserver with Rhino in "jack" (jackjs.org, like Ruby's Rack but for JavaScript), but I prefer it over Jetty anyway due to it's small size and simplicity, and it seems little faster too. Thanks. |

Hi,
Either is fine, Request.getTarget provides you with the unparsed URI. So it will contain the path, the fragment, and the query, which will be URL encoded. The getAddress method allows you to extract everything in a normalized fashion. I think getAddress().getPath().toString() is the best option. Then extract the fragment from that.

Hi,I'm having some trouble getting access to the fragment identifier component of a URI. Is this possible in SimpleFramework?
I'd like to be able to access the 'fragment' in this URI: http://server/page?query#fragment
At the moment all I get is up to the end of the query when I do a:
request.getAddress().toString()or arequest.getTarget()
Any help is appreciated.
Thanks,T
here's the full code that I'm using to test this:
import org.simpleframework.http.core.Container;import org.simpleframework.transport.connect.Connection;import org.simpleframework.transport.connect.SocketConnection;import org.simpleframework.http.Response;import org.simpleframework.http.Request;import java.net.InetSocketAddress;import java.net.SocketAddress;import java.io.PrintStream;
public class HelloWorld implements Container { public void handle(Request request, Response response) { PrintStream body; try { body = response.getPrintStream(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); return; } long time = System.currentTimeMillis();
response.set("Content-Type", "text/plain"); response.set("Server", "HelloWorld/1.0 (Simple 4.0)"); response.setDate("Date", time); response.setDate("Last-Modified", time);
body.println("Hello World" + "\nGetAddress = " + request.getAddress().toString() + "\nGetTarget = " + request.getTarget()); body.close(); } /** * @param args */ public static void main(String[] list) throws Exception { // TODO Auto-generated method stub Container container = new HelloWorld(); Connection connection = new SocketConnection(container); SocketAddress address = new InetSocketAddress(8000);
connection.connect(address); }
}

Subject: [Simpleweb-Support] Typo in FileAllocator
Hi,
There is a type in one of the FileAllocator's constructor
84 public FileAllocator(String prefix) throws IOException {
85 this(PREFIX, 1048576);
86 }
Should be
84 public FileAllocator(String prefix) throws IOException {
85 this(prefix, 1048576);
86 }
