The terminal device related to the invention can be computer equipment used in mobile, and broadly includes mobile phones, notebooks, POS machines and even vehicle-mounted computers, and is not particularly limited herein.
The program exception handling method of the present invention is described below with reference to fig. 1, 2 and 3. As shown in fig. 1, the program exception handling method provided by the present invention includes:
step 101: hooking a first function of an operating system, wherein the first function is a function for executing an abnormal event distribution operation of the operating system at an application layer;
in this step, the first function of the operating system (the unprocessed exception filter function Unhandled Exception Filter) is hooked, and the first function of the operating system refers to hooking the first function (the function that performs the exception event distribution operation of the operating system at the application layer) in the operating system, so that the operating system will automatically call the callback function to perform the operation desired by the operator. Wherein exception distribution refers to the distribution of exceptions by an operating system to a debugger or processing function of an application.
Step 102: calling a second function to monitor an abnormal event and acquiring abnormal processing information corresponding to the abnormal event;
in this step, a second function (tangent function Detour) is called to monitor an abnormal event, and when the abnormal event occurs, the abnormal processing information (abnormal pointer) corresponding to the abnormal event is acquired.
Step 103: and sending the exception handling information to each module, performing pre-processing by each module according to the exception handling information, and executing repairing operation on the exception event through the pre-processing.
In this step, the exception handling information is sent to each module, so that before the top-level exception handler is invoked, the exception is pre-handled by a plurality of modules, and if the exception is repaired in the pre-processing, the top-level exception handler does not need to be invoked.
In this step, it should be noted that the exception handling information is sent to each module one by one, that is, the exception handling information is to be sent to each module, that is, a one-to-many sending operation, so that each module performs a pre-processing according to the received exception handling information, and further performs a repairing operation on the exception event through the pre-processing.
According to the exception handling method, the first function of the operating system is hooked, wherein the first function is a function for executing exception event distribution operation of the operating system at an application layer, then a second function is called to monitor exception events, exception handling information corresponding to the exception events is obtained, the exception handling information is sent to each module, each module carries out pre-processing according to the exception handling information, and repairing operation is carried out on the exception events through the pre-processing. Therefore, the invention can monitor the abnormal event by calling the second function and send the abnormal processing information corresponding to the abnormal event to each module, so that each module can pre-process the abnormal event according to the received abnormal processing information, the multi-module can capture the abnormal event together and repair the abnormal event, the limitation that the prior art can only carry out abnormal capture and abnormal repair on a single module is eliminated, and the abnormal processing efficiency of the computer is greatly improved.
Based on the content of the foregoing embodiment, in this embodiment, before hooking the first function, the method further includes:
creating an abnormal function table;
and under the condition that the module is loaded, inserting a first exception handling function corresponding to the module into an exception function table.
In this embodiment, the exception function table is used to record a call function of the operating system when exception processing is performed. The first exception handling functions corresponding to the modules are exception handling functions in each module, the exception handling functions are different, and the capability of handling exception events is different. Before hooking Unhandled Exception Filter functions, judging whether an operating system establishes an exception function table (a modularized exception distribution function table), if not, firstly establishing the modularized exception distribution function table, and inserting exception processing functions corresponding to all modules into the modularized exception distribution function table. If the dynamic link library module DLL (Dynamic Link Library) is the dynamic link library module, the exception handling function corresponding to each module is inserted into the table tail of the modularized exception distribution function table. If the program module EXE (EXE File) is the executable program module EXE, the exception processing function corresponding to each module is inserted into the table head of the modularized exception distribution function table. Because the clearing of an EXE module from memory typically means a complete exit of the process (application), the life cycle of the EXE in memory is the life cycle of the process, and thus, in order to avoid unnecessary performance loss, the functions of the EXE module are inserted into the header. Where function insertion is the concept of replacing calls to functions in a dynamic library with calls to user-defined wrappers.
In this embodiment, a plurality of modules share one exception distribution function table, and each module is provided with an exception handler of the corresponding module itself. An exception handler includes an exception handling function.
Based on the content of the above embodiment, in the present embodiment, the exception handling information is sent to each module, each module performs a pre-process according to the exception handling information, and a repair operation is performed on an exception event by the pre-process, including:
calling a first exception handling function and sending exception handling information to the first exception handling function;
and the first exception handling function performs corresponding exception repairing processing according to the first association degree of the exception handling information and the module.
In this embodiment, current exception handling information is sequentially transferred to the exception handling functions corresponding to each module in the modularized exception distribution function table, and tolerance measures are taken for exceptions by the exception handling functions of each module according to the current exception handling information, that is, the modules may or may not handle the exceptions. Specifically, after the module receives the exception handling information, the module first judges the association degree of the exception information and the module itself, so that whether the module has the capability of repairing the exception or not can be understood, and if the module does not handle the exception, the module transfers the exception to the next flow. The exception handling method provided by the invention can be used for carrying out pre-processing on the exception by a plurality of modules before the top-level exception handler is called, and the top-level exception handler is not required to be called if the exception is repaired in the pre-processing, so that the problem that in the prior art, the exception handling can only be carried out in a single module is solved, the exception handling of a plurality of modules in the same process is realized, a more effective way is provided for exception repair and exception filtering, and the exception handling capability of a computer is improved.
Based on the foregoing embodiment, in this embodiment, the first exception handling function performs corresponding exception repair processing according to a first association degree of exception handling information and a module, including:
under the condition that the abnormality processing information is generated by the module, generating a first abnormality repair instruction, and executing the abnormality repair operation of the module according to the first abnormality repair instruction;
and generating a second abnormality repair instruction under the condition that the abnormality processing information is not generated by the module, and executing the module abnormality neglecting operation according to the second abnormality repair instruction.
In this embodiment, it should be noted that, each module may generate a corresponding exception handling instruction according to the exception handling information, where the exception handling instruction is used for the module to execute a module to repair an exception operation, or execute the module to ignore the exception operation, where the module exception ignore operation may be understood that the current module does not process an exception event. When the module is repaired after the module is operated to repair the abnormal operation, the subsequent steps are not performed any more, the repaired information of the abnormal operation is directly returned to the second function, and if the abnormal operation is not repaired or the module is operated to ignore the abnormal operation, the current abnormal operation is filtered, and the abnormal processing information is distributed to the next flow.
Based on the foregoing embodiment, in this embodiment, after each module performs the pre-processing according to the exception handling information, the method further includes:
the exception handling information is sent to each module, and each module carries out post-processing according to the exception handling information;
determining unrepaired abnormal events according to post-processing, and acquiring abnormal processing information of the unrepaired abnormal events;
and generating a report or terminating the application program according to the abnormal processing information of the unrepaired abnormal event.
In this embodiment, it should be noted that, after the module performs the pre-processing according to the exception handling information, the pre-processing unrepaired exception and/or the exception ignored by the pre-processing are obtained through filtering, then the top-level exception handler is called, the exception is repaired again according to the exception handling function corresponding to the top-level exception handler, if the exception is repaired, the information that the exception has been repaired is returned to the second function, if the exception has not been repaired, the unrepaired exception in the top-level processing is sent to each module, so that each module performs the post-processing according to the exception handling information, and determines the exception that may cause program crash. It should be noted that, the exception filtered by the top-level exception handler may cause a program crash, so after the current exception pointer is transferred to each module, each module retains the exception that causes the program crash, and uploads to the system to generate an error report or terminate the application program, so as to inhibit the operating system from reporting the "crash" behavior to the user, and realize silent exit. It should be noted that exceptions that the top level exception handler fails to repair are typically catastrophic, but this does not mean that the code of the application program is not able to continue to function properly at all, and some specially constructed code may still be run when the program is about to "crash". The exact meaning of "crash" is that the operating system, upon detecting an irreparable exception to the application, hangs the application, notifies the user and terminates the application's behavior.
Based on the content of the above embodiment, in this embodiment, the exception handling information is sent to each module, and each module performs post-processing according to the exception handling information, including:
calling a second exception handling function, and sending exception handling information to the second exception handling function;
and the second exception handling function performs corresponding re-exception repair processing according to the second association degree of the exception handling information and the module.
In this embodiment, the second exception handling function refers to a handling function corresponding to each module, exception handling information is sent to the exception handling function of each module, association degree between the exception handling information and itself is determined by the exception handling function of each module, and exception repair processing is performed again.
In this embodiment, the post-processing may optionally include generating an error report according to the exception handling information, and performing vectorized exception continuing processing according to the error report. Vectorized exception continued processing corresponds to a continued processor from which deterministic work is made after the exception has been processed through the above-described flow.
Based on the foregoing embodiment, in this embodiment, the method further includes, before sending the exception handling information to each module and performing post-processing according to the exception handling information by each module:
and sending the exception handling information to each module, and performing top layer processing by each module according to the exception handling information.
Based on the content of the above-described embodiment, in the present embodiment, in the case where an abnormal event has been repaired in the pre-processing, or in the case where an abnormal event has been repaired in the post-processing, or in the case where an abnormal event has been repaired in the top-level processing, an abnormal repaired information notification is returned to the second function.
Based on the foregoing embodiment, in this embodiment, the exception handling information is sent to each module, and before each module performs the pre-processing according to the exception handling information, the method further includes:
judging whether the abnormal event is possibly repaired;
under the condition that the abnormal event is possibly repaired, the abnormal processing information is sent to each module to carry out pre-processing;
in the event that the exception event cannot be repaired, the first function of the operating system is recalled.
In this embodiment, optionally, the case that the exception belongs to unrepairable includes: the exception is currently being one or more of nested, an exception due to a resource transformation, and an exception due to a deadlock. When any one of the conditions occurs, the exception cannot be processed through the subsequent steps, at this time, the exception processing information is not sent to each module any more, and the Unhandled Exception Filter function is directly called. Specifically, the following operations are performed in the second function:
a) If the exception is being nested, no further steps are performed, directly returning to the Unhandled Exception Filter function;
b) If the resource conversion causes the exception, the subsequent steps are not executed any more, and the method directly returns to the Unhandled Exception Filter function;

d) Calling functions in the modularized exception distribution function table one by one, transmitting current exception pointers to the functions, and performing pre-filtering;
e) Calling a top layer exception handler;
f) Calling functions in the modularized exception distribution function table one by one, transmitting current exception pointers to the functions, and performing post-filtering;
g) If the result of either step d) or e) indicates that the EXCEPTION has been repaired (an EXCEPTION has been identified as returned to the exception_context_exception), then no further steps are performed, and the exception_context_exception is returned directly (to the caller-the EXCEPTION has been repaired).
The exception nested finger function also has an exception handler, which may cause nesting exception, and the exception instruction caused by resource conversion is that the compiler automatically converts the class when running the program, and deadlock refers to a blocking phenomenon caused by competing resources or communicating with each other in the execution process of two or more processes, and if no external force acts, the two or more processes cannot be advanced.
