Description
Technical field
The present invention relates to Internet technical field, in particular to a kind of synergic debugging system and method based on Web.
Background technique
With the development of 2.0 technology of Web, realize that system-level application has become the master of modern technologies based on Web technology
Stream.Gradually it has been changed into the application technology of C/S (client/server) mode and has been with B/S (browser/server) mode
Main low cost, lightweight application, and be used widely in all trades and professions.
J2EE technology is a kind of enterprise web application exploitation solution based on Java, not only inherits Java platform
Plurality of advantages, while additionally providing to EJB (Enterprise JavaBeans), Java Servlets API, JSP (Java
Server Pages) and XML technology comprehensive support, enormously simplify enterprise-level application development.In addition, integrated as one
Development platform, J2EE have many advantages, such as that availability is strong, high reliablity, scalability are good again.
Debugging is essential link in modern software exploitation, and is generally required specially for operating system kernel level debugging
The debugging tool of door, such as debugging tool GDB popular at present, such one side developer need to configure specific tune
Test ring border, increases debugging cost；On the other hand, Debugging message is often difficult to directly understand, increases the debugging of ordinary user
Difficulty.
GDB/MI is a kind of more important other than CLI (Command Line Interface) order of GDB offer
Command interface, it commonly used in building complication system debugging tool, deposited as a debugging component in complication system
?.For example, the GUI debugger using GDB as debugging tool realized in Insight just takes full advantage of GDB/MI.But
It is that the output information format of GDB/MI is complex, needing to be familiar with its format could correct understanding.
QEMU is the widely used open source simulator on GNU/Linux platform, and with lightweight, speed is fast, it is more to support
The advantages that kind platform architecture.QEMU supports two kinds of operating modes of user class mode and system-level mode, wherein system-level operations mould
Formula can be such that unmodified kernel or operating system runs under simulated environment, be that system debug and cross-platform operate
Provide good platform.
The existing debugging tool for operating system kernel level application does not have friendly gui interface usually, and debugs
Process is complicated, needs higher debugging cost.

Include the following steps：
(331) debugging request that the HTTP server module parsing Web client browser module is sent, executes corresponding behaviour
Make, mainly includes the following steps that：
(a) when the debugging request received exits command for Quit, then the order of an interruption GDB server is issued；
(b) when the debugging request received is Set/Remove Breakpoint or Set/Remove

(c) when the received debugging request be Memory check that memory information or Register check register information, then
The order for checking memory information or register information related pattern is issued to GDB server debugging module；
(d) when the received debugging request is that Pause suspends or Run continues to execute order, then to GDB server debugging mould
Block, which issues to interrupt, executes or continues to execute order；
(e) when the received debugging request is that Step single step executes order, then to GDB server debugging module sending single step tune
Examination order is that basic debugging unit single step executes with function.
(332) debugging request after parsing is sent to the GDBWrapper message modulus of conversion by the HTTP server module
Debugging request is converted to the executable GDB/MI of GDB server debugging module by block, the GDBWrapper message conversion module
Order, and the debugging result that the GDB server debugging module returns is received, the debugging result is converted into corresponding data
