Description

Web-based collaborative debugging system and method
Technical Field
The invention relates to the technical field of internet, in particular to a collaborative debugging system and method based on Web.
Background
With the development of Web 2.0 technology, the realization of system-level applications based on Web technology has become the mainstream of modern technology. Application technologies in the C/S (client/server) mode have gradually shifted to low-cost, lightweight applications mainly in the B/S (browser/server) mode, and are widely used in various industries.
The J2EE technology is an enterprise-level Web application development solution based on Java, not only inherits many advantages of a Java platform, but also provides comprehensive support for EJB (Enterprise JavaBeans), Java Server APIs, JSP (Java Server pages) and XML technologies, and greatly simplifies enterprise-level application development. In addition, as an integrated development platform technology, the J2EE has the advantages of strong usability, high reliability, good expandability and the like.
Debugging is an essential link in modern software development, and special debugging tools such as the current popular debugging tool GDB are often needed for kernel-level debugging of an operating system, so that on one hand, developers need to configure a specific debugging environment, and the debugging cost is increased; on the other hand, debugging information is often difficult to directly understand, and debugging difficulty of common users is increased.
GDB/MI is a more important command interface provided by GDB besides CLI (Command Line interface) commands, and is usually used for building a debugging tool of a complex system, and exists as a debugging component in the complex system. For example, a GUI debug implemented in Insight with GDB as a debugging tool takes full advantage of GDB/MI. However, the output information format of the GDB/MI is complex and needs to be familiar with the format for proper understanding.
QEMU is an open source simulator widely used on GNU/Linux platform, and has the advantages of light weight, high speed, support of various platform architectures and the like. The QEMU supports two working modes, namely a user-level mode and a system-level mode, wherein the system-level working mode can enable an unmodified kernel or an unmodified operating system to run in a simulation environment, and a good platform is provided for system debugging and cross-platform application operation.
The existing debugging tools for operating system kernel-level applications generally do not have friendly GUI interfaces, and the debugging process is complex and requires high debugging cost.
