    <p>Help to build python ForkingTCPServer. This server returns an error when client connects to the server. When I use ThreadingTCPServer instead of ForkingTCPServer it works fine. socketFileIO module contains functions for pickle to/from socket: <a href="http://code.activestate.com/recipes/577667-pickle-tofrom-socket/" rel="nofollow">http://code.activestate.com/recipes/577667-pickle-tofrom-socket/</a></p> <p>server.py:</p> <pre><code>import SocketServer, time from socketFileIO import write, read class MyClientHandler(SocketServer.BaseRequestHandler): def handle(self): print self.client_address data=read(self.request) print 'Client:', data time.sleep(10) # for testing write(self.request,data) self.request.close() HOST, PORT = '', 50007 server = SocketServer.ForkingTCPServer((HOST, PORT), MyClientHandler) server.serve_forever() </code></pre> <p>client.py:</p> <pre><code>import socket from socketFileIO import write, read HOST = '127.0.0.1' PORT = 50007 data=["A","B","C","End"] for x in data: s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((HOST, PORT)) write(s,x) y=read(s) print 'Server:', y s.close() </code></pre> <p>Error:</p> <pre><code>---------------------------------------- Exception happened during processing of request from ('127.0.0.1', 1469) Traceback (most recent call last): File "c:\Python26\lib\SocketServer.py", line 283, in _handle_request_noblock self.process_request(request, client_address) File "c:\Python26\lib\SocketServer.py", line 525, in process_request pid = os.fork() AttributeError: 'module' object has no attribute 'fork' ---------------------------------------- </code></pre> <p>I have a several other questions:</p> <ol> <li>How to shutdown the server by sending data "End" from client ?</li> <li>How to restrict the number of connections (for example no more then 5) ?</li> </ol>

    3. CONope. You can probably write something similar with Twisted or `multithreading` instead.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
