Abstract
The invention discloses a positioning method and a positioning system for thread anomaly. The positioning method for the thread anomaly comprises the following steps. Running states of monitored threads are monitored, and whether the monitored threads run abnormally is judged; when the monitored threads are judged to be abnormal, a dump file is generated, and the dump file comprises internal storage and stack information of the threads in a process; by debugging the dump file, a code position of the anomaly of the monitored threads is positioned. According to the positioning method and the positioning system for the thread anomaly, not only can the running states of the threads be monitored, but also when the threads run abnormally, due to the fact that the dump file automatically records the currently running internal storage and the stack information of the threads, developers can rapidly position the code position causing the anomaly of the threads according to the recorded internal storage and the stack information.
Description
Technical field
The present invention relates to field of computer technology, relate in particular to the abnormal localization method of a kind of thread and system.
Background technology
Thread is the elementary cell of operating system distribution processor time, and a plurality of threads run time version simultaneously can be arranged in process.Each thread maintenance abnormality handling procedure, dispatching priority and a group system are used for preserving the structure of thread context before this thread of scheduling.The method of existing monitoring thread running status has two kinds:
Heartbeat detection: whether set up a monitoring thread, monitoring each thread has heartbeat, if in a period of time, certain thread does not have heartbeat, thinks that this thread is abnormal;
Status poll: set up a monitoring thread, inquire about at set intervals the running status of each thread, if find that certain thread operation stops, and thinks that this thread is abnormal;
The total major defect of above two kinds of prior aries is:
State that can only monitoring thread is if thread can not be determined the particular location that thread is abnormal extremely;
When carrying out the complicated and time consumption computing, adopt above two kinds of technology may have the situation of erroneous judgement thread running status when thread.
Summary of the invention
The technical matters that (one) will solve
The technical problem to be solved in the present invention is: the abnormal localization method of a kind of thread and system are provided, cause with quick location the code position that thread is abnormal.
(2) technical scheme
For addressing the above problem, on the one hand, the invention provides the abnormal localization method of a kind of thread, comprising:
Monitor the running status of each monitored thread, judge whether monitored thread operation is abnormal;
Generate dump file when judgement obtains monitored thread abnormal, described dump file comprises internal memory, the stack information of in-process each thread;
By debugging described dump file, locate the code position at the abnormal place of monitored thread.
Preferably, also comprise the step that increases monitoring thread before the step of the running status of the monitored thread of described monitoring, monitor the running status of each monitored thread by described monitoring thread.
Preferably, monitor the running status of each monitored thread by described monitoring thread, judge whether abnormal step comprises in monitored thread operation:
Described each monitored thread is registered to described monitoring thread when initialization, and sets initial value and the abnormal number of times limit value of the time-out time of each monitored thread, the initial value of counter, abnormal number of times;
Each monitored thread upgrades the counter of self in normal course of operation;
If monitoring thread is found certain monitored thread and do not upgrade the counter of self in the time-out time of described setting, adds 1 for the abnormal number of times of this monitored thread;
If abnormal number of times corresponding to monitored thread be greater than the abnormal number of times limit value of described setting, judgement this monitored thread abnormal, and the counter that this monitored thread is corresponding and extremely number of times reset to the initial value of correspondence.
Preferably, if abnormal number of times corresponding to described monitored thread is greater than the abnormal number of times limit value of described setting, the step that judges this monitored thread abnormal comprises: if continuous abnormal number of times corresponding to monitored thread greater than the abnormal number of times limit value of described setting, this monitored thread abnormal of judgement.
Preferably, if monitoring thread is found certain monitored thread and do not upgrade the counter of self in previous time-out time, but upgraded the counter of self in current time-out time, the abnormal number of times that described monitored thread is corresponding resets to corresponding initial value.
Preferably, also be included in daily record after the step of this monitored thread abnormal of judgement in the step of identifier of recording exceptional thread.
Preferably, the step of described debugging dump file comprises: find corresponding abnormal thread according to the identifier of described abnormal thread.
Preferably, described dump file is the dmp file.
On the other hand, the present invention also provides a kind of thread abnormal positioning system, comprising:
Monitoring module for the running status of each monitored thread of monitoring, judges whether monitored thread operation is abnormal;
The dump file generation module is used for generating dump file when judgement obtains monitored thread abnormal, and described dump file comprises internal memory, the stack information of in-process each thread;
Abnormal locating module is used for locating the code position at the abnormal place of monitored thread by the described dump file of debugging.
(3) beneficial effect
The present invention can not only the monitoring thread running status, and when the thread operation exception, internal memory and stack information by the current operation of the automatic record thread of dump file, the developer is according to internal memory and the stack information of record, just the code position that causes that thread is abnormal be can locate fast, debugging and the reparation of thread facilitated.
Continuous abnormal number of times corresponding to the monitored thread of the present invention just judges this monitored thread abnormal during greater than the abnormal number of times limit value of described setting, can reduce the probability of some thread erroneous judgement complicated and consuming time.
Method of the present invention increases monitoring thread can be completed, and the scope of application is wider, also applicable to announced software.
