问题 I'm new to nodejs and trying to write a chat room as so many people have. The chat consists of multiple rooms and clients. Commands such as /nick /join /help /ls users /ls rooms work as you would expect although I'm having trouble with getting a /kick command to work. I'm just not sure how you disconnect a client by id, so far /kick client is able to present the respective clients socket.id although I'm stuck for the code to kick via socket.id. Code so far: Disconnect client who sent /kick :

问题 My SQL Server 2005 doesn't restore a backup because of active connections. How can I force it? 回答1: SQL Server Management Studio 2005 When you right click on a database and click Tasks and then click Detach Database , it brings up a dialog with the active connections.

问题 I spent ages trying to find a simple example where MongoEngine was being used and a connection was being closed. Finally figured it out and posting my code. 回答1: I know this is an old question, but if anyone else is searching I figured I'd give an alternate answer. close() does not actually remove the connection from MongoEngine's connection list. This causes problems when trying to connect to a different database later on. To solve this I used mongoengine.connection.disconnect (even though

问题 I want to send disconnect event manually with custom parameter to socket.io server. I use this function but won't work: //client var userId = 23; socket.disconnect(user); //Server socket.on('disconnect', function (data) { console.log('DISCONNECT: '+ data) }) Now how can I send a additional data to server when disconnect event sent? 回答1: Socket IO's disconnect event is fired internally but you can emit a custom event when it is called. You need to first listen for the disconnect event. Once

问题 I have read and deeply understood these: http://www.php.net/manual/en/features.connection-handling.php http://www.php.net/manual/en/function.register-shutdown-function.php However, I have tested both PHP 5.1.6 and 5.3 and things DON'T work as described there.

问题 Ok what the heck is up with iOS6 and how it handles Bluetooth LE disconnections? Before the device would disconnect immediately but now, for some strange reason, the device waits to disconnect for about 30-60 seconds. I need it to disconnect ASAFP! I've been searing all over the internet trying to figure out how to initiate an immediate disconnection from the peripheral and I found this nifty email that explains a workaround is to unsubscribe from notifications on the service characteristics.

问题 I have two simple applications: A Server application that waits on a specific tcp port for a client to connect. Then listens to what he says, send back some feedback and DISCONNECT that client. A Form application that connects to the server application, then says something, then wait for the feedback and disconnect from the server, then show the feedback in the form. Though the server application seems to behave correctly (I have tested it with Telnet and I see the feedback and I see the

问题 I need to make MySQL server to rollback transaction immediately after its client disconnected, because each client works concurrently. The problem can be reproduced like these (using an innodb table type) On Client A: START TRANSACTION; SELECT MAX(ID) FROM tblone FOR UPDATE; #... then disconnect your connection to the server On Client B: START TRANSACTION; SELECT MAX(ID) FROM tblone FOR UPDATE; #... lock wait time out will occur here I had set MySQL's server option like innodb_rollback_on
