BT source code learning experience (7): Code Analysis of Tracking Server (HTTP protocol processing object)Author: Wolfenstein (neversaynever) The last time we analyzed the initialization process of the tracker class, we started to look at how the tracking server provides services.First, we analyze that the tracker processing object is httphandler, which is defined in BitTorrent/httphandler. py. The initiali

The USB Nic is divided into wireless 3G and wired, and wireless 3G Nic has been implemented by my colleagues. I recently implemented wired Nic. That is, connect to the mid through RJ45 to USB, and the driver will register the ethx network device. What I want to achieve is to operate the network device. Connectivityservice is a service that manages connections. It manages multiple network types of tracker, such as wifistatetracker and mobiledatastatet

Install and configure FastDFS_v5.05 on CentOS FastDFS_v5.05 is installed on the new server. There are still many changes compared with FastDFSV3.02. Now we will record the installation and configuration process for your reference. For security considerations, where IP addresses are involved, you can use IP202.98.27.31 at will. When the traffic is low, you can deploy tracker and storage on the same server. Later, you can scale the

and is in the application layer of the TCP/IP architecture. According to the BitTorrent protocol, a file publisher will provide a. torrent file, which is a seed file, or "seed", based on the file to be published. The torrent file is essentially a text file that contains tracker information and file information in two parts. Tracker information is mainly used in BT download the address of the

You can find a series of GATT-based profiles and service on bluetooth.org.1.2 Roles and functionsHere are some of the applicable roles and functions of an Android device when interacting with a BLE device:* Central equipment and peripheral equipment. This applies to the connection of the BLE itself. The device that serves as the central device role is responsible for

MogileFS Distributed File System Construction MogileFS is an open-source distributed storage software suitable for storing massive small files. It consists of three parts: tracker, mogstore, and database.Tracker: It stores metadata information through databases, including site domain, class, host, etc. Its main functions include monitoring back-end Storage nodes, and instructing Storage nodes to add, delete, and query data, and data replication betwee

this article, I created a simple ModifiedObjectTracker, which clearly knows the insert, update, and delete operations through the Hibernate event listener. This tracker maintains a unique number for each view of the application, and a Hibernate ing about which Hibernate entities affect each view. Every time a POJO is changed, the counter that uses the view of the object is added with 1. We use this count value as the ETag, so that when the client sen
