send

After sending a lot, my send() call causes my program to stall completely. How is this possible?

问题 So basically I'm making an MMO server in C++ that runs on linux. It works fine at first, but after maybe 40 seconds with 50 clients it will completely pause. When I debug it I find that basically the last frame its on before it stops responding is syscall() at which point it disappears into the kernel. Once it disappears into the kernel it never even returns a value... it's completely baffling. The 50 clients are each sending 23 bytes every 250 milliseconds. These 23 bytes are then

Send/Receive messages at the same time socket python

问题 I have been working on a simple python socket chat room where the client and server can send messages to each other. The issue that I came across was that the server and client can only send one message at a time. I want it to work like any other chat room, where I could receive a message when I am sending a message, any help will help greatly Server.py import socket import sys s = socket.socket() host = socket.gethostname() print(" server will start on host : ", host) port = 8080 s.bind(

SpringAMQP RabbitMQ how to send directly to Queue without Exchange

由 折月煮酒 提交于 2019-12-06 03:48:08
I'm using SpringAMQP with Rabbit template. How to send messages directly to Queues omitting Exchange? How can i do it? How can i do it? You can't; publishers don't know about queues; just exchanges and routing keys. However, all queues are bound to the default exchange ( "" ) with the queue name as its routing key. If you are using Spring AMQP's RabbitTemplate , it is configured to publish to the default exchange by default, so you can use convertAndSend("myQueue", "foo")` Or even... template.setDefaultRoutingKey("myQueue"); then template.convertAndSend("foo"); or template.send(aMessage); 来源：

python's selenium “send_keys” with chrome driver drops characters

问题 I am using selenium package with Python (https://pypi.python.org/pypi/selenium) with Windows 7. When I try to login to my facebook account I use the send_keys command, e.g. elem = browser.find_element_by_name("email") elem.send_keys(email); elem = browser.find_element_by_name("pass") elem.send_keys(password); Login fails apparently because the second send_keys drops the first character of the password (I found this by directly sending the password characters to the email field.

Ruby difference between send and instance_eval?

由 血红的双手。 提交于 2019-12-06 00:00:40
问题 I know send takes string or symbol with arguments while instance_eval takes string or block, and their difference could be apparent given receivers. My question is what the ' under the hood ' difference is for the example below? 1234.send 'to_s' # '1234' 1234.instance_eval 'to_s' # '1234' 回答1: From the fine manual: send(symbol [, args...]) → obj send(string [, args...]) → obj Invokes the method identified by symbol , passing it any arguments specified. [...] When the method is identified by a

TcpClient send/close problem

由 [亡魂溺海] 提交于 2019-12-05 18:39:16
Do I need to close the connection to have messages actually sent? Because whether I use send command or use a network stream, my messages don't get processed until I close connection. Is that the way it's supposed to be or am I missing something? Ok here's the code. private void connectButton_Click(object sender, EventArgs e) { try { client = new TcpClient(); client.Connect(ip, port); netStream = client.GetStream(); } catch (Exception ex) { MessageBox.Show(ex.Message); } } private void disconnectButton_Click(object sender, EventArgs e) { if (client != null) { if (client.Connected) { client

问题 Some application ask the user if they want to send the crash log by email when they restart after a crash. How are they doing that ? They have to record the log when they crashing and reads this file and ask the user to send it if it's not empty ?

Check that write()/send() can process whole buffer without block, fail otherwise (no partial write)

由 谁都会走 提交于 2019-12-05 18:05:50
I am using SOCK_SEQPACKET connection, and it is critical for me to ensure that whole buffer is sent with single write()/send() call. I am also operating with device driver that is designed to handle a complete block of data with single call. At the same time I want to handle the situation when write()/send() blocks due to buffer overflow, i.e. I want to have a feedback whether current implementation gets a bottleneck here. I'm working with glibc, Linux 2.6. I need to implement a method that accepts a buffer, and it either sends a buffer completely or indicates a failure due to blocking (i.e.
