Problems solved by technology

[0004] However, the technology described in the above-mentioned Conventional Example 1 only treats one type of event as the work history "execution of a function" as an object of restoration.
Furthermore, the technology described in the above-mentioned conventional example 2 only targets changes in one type of information, the "value of a processing variable" as a retrieval condition.
That is, in the prior art, the occurrence of various events occurring during application execution cannot be grasped, and information related to various events cannot be set as search conditions.
[0005] Furthermore, in applications executed on a multitasking OS, there are events such as interrupt processing whose timing cannot be predicted.
Furthermore, when the above-mentioned prediction cannot be performed but normal processing is included in the recorded work history, it must be processed as a normal event
However, in the technology disclosed in the above-mentioned prior art example 1 and the technology disclosed in the above-mentioned prior art example 2, since it cannot be judged whether it is a normal event or an abnormal event, the operator must make a judgment related to it, and suffers a large burden due to repair. time constraints

Embodiment 1

[0043] figure 1 It is a functional configuration diagram of the tracking information retrieval device 1000 in this embodiment. Moreover, in figure 1 Among them, the target application 1010 is a program to be repaired by the tracking information retrieval device 1000 .

[0044] The target application 1010 is composed of an application program module 1011 and a multitasking OS (Operating System) 1012 . The application module 1011 is composed of one or more tasks working on the multitasking OS 1012 .

[0045] The multitasking OS 1012 has a function for outputting the status of the OS in execution of the application module 1011 and information indicating the occurrence of events such as task switching, interrupt, and system call issuance (hereinafter referred to as "event occurrence information"). Features.

[0046] The tracking information retrieval device 1000 is composed of a tracking information storage unit 1100 and a tracking information retrieval unit 1200 . Furthermor...

Embodiment 2

[0085] In the above-mentioned first embodiment, the tracking information retrieval device capable of setting retrieval conditions including various task transitions was described, but in this embodiment, the retrieval conditions can be set using a sequence chart. A tracking information search device for displaying search results and the like will be described.

[0086] Figure 9 It is a functional configuration diagram of the tracking information retrieval device 2000 according to this embodiment. exist Figure 9 Among them, the target application 1010 is a program to be repaired by the trace information retrieval device 2000, and is the same program as the target application 1010 in the first embodiment described above.

[0087] The tracking information retrieval device 2000 is composed of a tracking information storage unit 1100 and a tracking information retrieval unit 2200 . The configuration of the tracking information holding unit 1100 is the same as that of the track...

Abstract

The present invention provides a track information searching device and method. A trace information holding unit (1100) acquires and memorizes information indicating operations of an application program module (1011) (trace information) to be executed on a multitasking OS (1012). A search condition input unit (1210) accepts two or more pieces of information from an operator as search conditions. A search condition memory unit (1220) memorizes the accepted search conditions. A searching unit (1230) performs a search among the trace information stored in a trace information memory unit (1120) based on search conditions. A search result displaying unit (1240) displays a search result.

Description

technical field [0001] The present invention relates to a device supporting debugging of application programs executed on an OS (operating system), and more particularly to a device for displaying and verifying information indicating the operation status of application programs executed on a multitasking OS. Background technique [0002] In the prior art, in repair work of an application program (hereinafter referred to as "application") executed on a multitasking OS, a repair operator monitors the operation status of the application during execution, or Analyze the status through the history, thereby discover the abnormal operation of the application and correct it. [0003] As a technique for supporting such repair work and discovering abnormal operation in application, there is "processing monitoring device and processing monitoring method" (conventional example 1) disclosed in Japanese Patent Laid-Open Publication No. Hei 9-305443, Storing reference data corresponding t...
