Embodiment
Among the present invention, detect and occur extracting also record current environment information when unusual, thus the environmental information can reappear unusual the generation according to the environmental information of record the time, and then according to the environmental information of record to analyzing unusually.
Fig. 1 is the unusual flow chart that reappears among the present invention, and as shown in Figure 1, unusual concrete processing procedure of reappearing may further comprise the steps:
Step 101: it is unusual to detect appearance.4 kinds of exception error interrupt modes that can comprise ARM unusually, as undefined pattern (Undefined Mode), software interrupt pattern (SWI (SoftWare Interrupt) Mode), prefetch mode (Prefetch Mode), peek aborted pattern (Abort Mode), can also comprise other exception errors, as remove zero, operand for empty, internal memory overflows etc.
Step 102: extract and write down current environmental information.Environmental information is meant the relevant service data when appearance is unusual, can comprise ARM register information, mission bit stream, Exception Type, abnormal patterns, stack information etc.The ARM register can be visited at any time, therefore can obtain the ARM register information by the visit to the ARM register; Mission bit stream can obtain by current task (curr_task) signal; Exception Type can determine by exception error vector or current process information, the exception error vector is aimed at 4 kinds of exception error interrupt modes, and current process information is aimed at other exception errors; Abnormal patterns can obtain by the condition handler that reads ARM; Current stack register when stack information occurs unusually by reading obtains.
Step 103: when the environmental information when unusual need to reappear occurring, judge whether success of integrity check,, then continue execution in step 104 if successful; If failure finishes current flow process.Carrying out integrity check is can not carry out misoperation in order to guarantee, to the check of self whether normally carrying out.For software program, whether integrity check is exactly to check the program code of self to be distorted or destroy, if do not distorted or destroyed, and then integrity check success.
Step 104: according to the environmental information of record, the environmental information when the reproduction appearance is unusual.
Further, the attendant can be according to environmental information when unusual occurring to analyzing unusually of occurring, thereby the mistake of exception throw is repaired.
The concrete processing procedure that reappear to occur the environmental information when unusual in the step 104 is as shown in Figure 2:
Step 201: display device is carried out initialization, as display devices such as initialization LCD, if successful initialization then continues execution in step 202; If the initialization failure then finishes current flow process, finish further to show error message before the current flow process to the attendant.
Step 202: input equipment is carried out initialization, as keyboard is carried out initialization, if successful initialization then continues execution in step 203; If the initialization failure then finishes current flow process, finish further to show error message before the current flow process to the attendant.
Step 203: show the function of each input mode to the attendant, so that the follow-up maintenance personnel operate.
Step 204: by the environmental information of display device displayed record successively, show ARM register information, mission bit stream, Exception Type, abnormal patterns, stack information etc. successively as display device, if successfully show successively, then realize occurring the reproduction of environmental information when unusual, continued execution in step 205 then; If show failure successively, then finish current flow process, finish can further show error message before the current flow process to the attendant.During the environmental information of displayed record successively, the attendant can operate by corresponding input mode, as operation such as advances, retreats.
Step 205: whether prompting the attendant need to store, and storage then continues execution in step 206 if desired; If do not need storage, then finish current flow process.
Step 206: the environmental information that will occur when unusual is stored among the ROM of portable terminal, if store successfully, then points out to the attendant and stores successfully; If the storage failure then finishes current flow process, finish further to show error message before the current flow process to the attendant.
Owing to occur when unusual, can't normally visit the file system of portable terminal, for example, and encrypted file system (EFS, Encrypting File System), therefore, the environmental information that occurs when unusual need be stored among the ROM.For the attendant can be obtained when these environmental informations of needs, just need to be stored in the environmental information of ROM when portable terminal normally starts, be written in the file system of portable terminal: concrete processing procedure is: read the environmental information of storing among the ROM, this environmental information is write the file system of portable terminal.In the specific implementation, can store 4 files, respectively storage: the environmental information that before showed specifically can be the ASCII character form; The task control block of current task (TCB, Task Main Controller) information specifically can be binary format, and TCB is used to store various states and the signal message relevant with current task; The TCB information of task management part (TMC, Task Main Controller) task specifically can be binary format; The TCB information of user interface (UI, User Interface) task specifically can be binary format.
Fig. 3 is unusual reproducer structural representation among the present invention, and as shown in Figure 3, unusual reproducer comprises detecting unit, extraction unit, buffer unit and reproducing unit.Wherein, whether detecting unit is used for detecting and occurs unusually, sends notice to extraction unit detecting when unusual; Extraction unit is used for extracting current environmental information from the notice of detecting unit, and the environmental information of extraction is provided to buffer unit; Buffer unit is used for the environmental information that comes from extraction unit is carried out buffer memory; Reproducing unit is used for obtaining the environmental information of buffer unit buffer memory, the environmental information when the reproduction appearance is unusual.Reproducing unit comprises display unit, is used for being convenient to the attendant environmental information being analyzed to attendant's display environment information.Reproducing unit can further comprise input unit, is used for providing input mode to the attendant, is convenient to the attendant and operates.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
