Description

  The present invention relates to a method for evaluating a program.

  An application program running on a computer dynamically secures and uses resources provided by an OS (Operating System) as necessary. Then, when the reserved resource becomes unnecessary, the application program releases the resource.

  In the application program, if the resources are not released appropriately, the operation and performance of the entire system (OS) may be adversely affected. It is essential to avoid such a system trouble caused by a problem at the time of creating a program, which is called “resource leak”. Therefore, it is necessary to create a program so that resources are released at an appropriate timing.

  However, it is not easy to detect a failure of the system due to omission of release of a handle (a resource common to the entire system) in the development process. In the development process, it is common to check the operation by reviewing and testing the source code.

  The handle value is not a unique value from the start to the end of the program (when released, it may be the same value again), it is common to the entire program, and the handle is used even when using different functions provided by the OS. Confirmation is not easy, for example, by performing a release of a common function (Application Programming Interface, also referred to as API in the following).

  Further, since the handle is a resource common to the entire system, a failure related to the handle value is unlikely to occur unless the system load is large. Generally, in the development environment, since the number of handles themselves is small, the handle value is often unique. Therefore, at the time of evaluation, the program may operate normally and a failure may be overlooked.

  Here, as related technologies existing prior to the present application, there are, for example, the following patent documents.

  Japanese Patent Application Laid-Open No. 2004-151561 stores, in the trace information, the start and end of processing executed based on an accepted request, and object generation and release in an application server. There is disclosed a memory leak detection apparatus that displays a list of objects that are suspected of having a memory leak based on trace information when requested by a user.

  Patent Document 2 discloses an information processing apparatus that mediates a function call, logs the call process, and checks whether the paired function is normally completed.

  Patent Document 3 discloses a trace system that detects resources that have been allocated but not released based on log information stored by the OS.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

<First Embodiment>
FIG. 1 is a block diagram showing the configuration of the information processing apparatus according to the first embodiment of the present invention.

  The information processing apparatus according to the present embodiment includes a translation apparatus 10, an execution apparatus 20, and a recording apparatus 30.

  The translation device 10 includes a translation unit 11 and an analysis unit 12.

  The translation unit 11 translates the original program into an execution program (machine language).

  When the translation unit 11 translates the source program, the analysis unit 12 searches for a command related to the resource described in the source program, and when it is searched, processing for notifying the command to the monitoring unit 22 described later is added. Analyze the source program to generate a running program.

  The execution device 20 includes an execution unit 21 and a monitoring unit 22.

  The execution unit 21 executes an execution program.

  When the execution unit 21 executes the execution program, the monitoring unit 22 is activated by the process added by the analysis unit 12 and monitors the execution program regarding the instruction related to the resource and the calling relationship of the modules constituting the execution program. .

  The recording device 30 records the results obtained by the analysis unit 12 and the monitoring unit 22. That is, the storage device 30 stores the search result obtained by the analysis unit 12 and information from the monitoring unit 22 provided when the execution program is executed.

  As described above, in the first embodiment, it is possible to detect a resource leak at the time of program evaluation, and as a countermeasure, information for reference when adding processing for releasing resources is stored. There is an effect that can be.

  The reason is that the information processing apparatus according to the present embodiment adds a process by the analysis unit 12 when the program is translated, and records information on the handle in the recording apparatus 30 by the process added when the program is executed. .

<Second Embodiment>
Next, a second embodiment based on the information processing apparatus according to the first embodiment described above will be described. FIG. 2 is a block diagram showing the configuration of the information processing apparatus according to the second embodiment of the present invention. However, the configuration shown in FIG. 2 is an example, and the present invention is not limited to the information processing apparatus shown in FIG.

  The information processing apparatus according to the present embodiment includes a translation apparatus 100, an execution apparatus 200, a monitoring result recording apparatus 300, and a monitoring result display apparatus 400.

  The monitoring result recording device 300 is a device such as a disk capable of recording information notified from the translation device 100 and the execution device 200.

  The monitoring result display device 400 is a device that notifies the user of the information recorded in the monitoring result recording device 300 by, for example, displaying it on a screen or printing it on paper.

  The translation apparatus 100 includes a source program 101, a program translation unit 102, an execution program 103, and a program external reference analysis unit 104.

  The source program 101 is a program written in a programming language (for example, C language, COBOL language, etc.).

  The program translation unit 102 first adds a process to the handle instruction described in the original program 101. And the program translation part 102 translates the program which added the process, and produces the execution program 103. FIG.

  The execution program 103 is a program that can be executed by a computer.

  The program external reference analysis unit 104 searches for an instruction group related to the operation of the handle referred to by the execution program 103. The program external reference analysis unit 104 determines whether an instruction for releasing the handle is included in the execution program 103 when a command group related to the handle operation is included. Then, the program external reference analysis unit 104 records the determined result in the monitoring result recording device 300.

  The execution apparatus 200 includes a program execution unit 201, a resource monitoring unit 202, an inter-module reference analysis unit 203, and a resource information analysis unit 204.

  The program execution unit 201 executes the execution program 103 created by the translation apparatus 100. Here, it is assumed that the execution program 103 includes processes A to X, and each process includes an instruction related to a handle.

  When the execution program 103 is executed, each time an instruction related to a handle is executed, information related to the handle is notified to the resource monitoring unit 202 by a process added by the program translation unit 102. The resource monitoring unit 202 that has received the notification records the notified content in the monitoring result recording device 300. Depending on the processing characteristics of the execution program 103 and the evaluation contents, the resource monitoring unit 202 may operate synchronously with the execution program 103 or may operate asynchronously.

  Then, the resource monitoring unit 202 analyzes the inter-module reference information in the function module execution program 103 notified to the resource monitoring unit 202 by the inter-module reference analysis unit 203. The inter-module reference analysis unit 203 records the analysis result in the monitoring result recording device 300.

  Further, the resource monitoring unit 202 causes the resource information analysis unit 204 to analyze whether there is a problem with the content notified by the execution program 103. The resource information analysis unit 204 records the analysis result in the monitoring result recording apparatus 300.

  Below, the process of this embodiment is demonstrated in detail.

  First, the program translation unit 102 searches the instruction program related to the handle for the source program 101 to be translated, and adds notification processing. The instruction group related to the handle is, for example, an instruction group for performing a handle operation and a handle duplication instruction group. The program translation unit 102 translates the program to which the process has been added, and creates an execution program 103.

  FIG. 3A is a diagram illustrating an image of a source program before executing a program translation unit in the information processing apparatus according to the second embodiment of the present invention. FIG. 3B is a diagram illustrating an image of a source program in which processing is added by the program translation unit in the information processing apparatus according to the second embodiment of the present invention. Here, the source program shown in FIG. 3B is a program image in which processing is added to the source program shown in FIG. 3A by the program translation unit 102.

  The program translation unit 102 searches for a command group (function group called API or system call) for performing a handle operation on the source program shown in FIG. 3A. When an instruction group is found, the program translation unit 102 adds processing for notifying the contents of the handle operation to the instruction group. In FIG. 3A, the instructions for performing the handle operation are an open instruction, a read instruction, a write instruction, and a close instruction. The translation device 2 adds processing for notifying the resource monitoring unit 202 of the contents of the handle operation to each of these commands. In addition, the program translation unit 102 adds a process of notifying the contents to the copy instruction group (assignment statement) of the handle to the original program. The image of the program to which these processes are added is FIG. 3B. In FIG. 3B, the underlined portion is a process added by the program translation unit 102.

  The program translation unit 102 creates an execution program 103 by translating a program to which processing as shown in FIG. 3B is added.

  When the creation of the execution program 103 is completed, the program external reference analysis unit 104 searches the execution program 103 for an instruction group (function group) for performing a handle operation. Then, the program external reference analysis unit 104 determines whether an instruction relating to the release of the handle exists in the source program 101 based on the retrieved result. The program external reference analysis unit 104 records the determined result in the monitoring result recording apparatus 300 together with the search result.

  When there is no instruction for releasing the handle (for example, a close instruction), the program external reference analysis unit 104 determines that the handle may leak. The program external reference analysis unit 104 records the determined result in the monitoring result recording device 300. And the monitoring result display apparatus 400 can notify a user of the information recorded on the monitoring result recording apparatus 300 with the result of having translated the original program group 101, for example.

  FIG. 4 is a diagram for explaining an operation image at the time of executing a program in the execution device 200 of the information processing apparatus according to the second embodiment of the present invention.

  When the execution program 103 is executed in the program execution unit 201, the resource monitoring unit 202 receives a notification every time a command for operating the handle is executed by the process added by the program translation unit 102. As shown in FIG. 3B, the events to be notified are handle acquisition, release, reference, and replication. In this embodiment, open, close, read, write, and handle substitution are applicable.

  FIG. 5 is a flowchart illustrating the resource monitoring unit in the information processing apparatus according to the second embodiment of the present invention.

  Upon receiving the notification of the command for operating the handle, the resource monitoring unit 202 notifies the monitoring result recording apparatus 300 of the above-described event (step S510). The monitoring result recording device 300 records the notified event type (open, close, read, write, handle substitution) and the handle value in association with each other.

  Next, the resource monitoring unit 202 notifies the above-described event to the inter-module reference analysis unit 203 (step S520). When receiving the notification from the resource monitoring unit 202, the inter-module reference analysis unit 203 analyzes the calling relationship in the execution program 103 of the function module that is the notification source to the resource monitoring unit 202 and notifies the monitoring result recording apparatus 300 of it. For example, the processes A to X shown in FIG. 2 are actually configured by combining one or more function modules. For example, in the case of C language, a program is generally realized by so-called module programming in which each function having a main function as an entrance is divided into function modules and implemented. The inter-module reference analysis unit 203 analyzes the reference relationship from the main function to the function module containing the instruction that actually operates the handle. The method for analyzing the reference between modules uses a generally known existing method, and a description thereof is omitted here. The monitoring result recording apparatus 300 records the notified reference information between modules in association with the type of recorded event (open, close, read, write, handle substitution) and the handle value.

  Next, the resource monitoring unit 202 determines whether the notified event type refers to a handle value (step S530). If the event refers to a handle value (here, close, read, write) (“Yes” in step S530), the resource information analysis unit 204 is notified (step S540).

  FIG. 6 is a flowchart illustrating the resource information analysis unit in the information processing apparatus according to the second embodiment of the present invention. FIG. 7 is a diagram for explaining execution history information recorded in the monitoring result recording device in the information processing apparatus according to the second embodiment of the present invention. The execution history information is information stored in association with time, process and thread, type, inter-module reference information, handle value, and variable information (information on a variable to which the handle value is assigned). . In FIG. 7, the type is set as “acquisition” for open, “release” for close, “reference” for read and write, and “set” for handle substitution.

  Upon receiving the notification from the resource monitoring unit 202, the resource information analysis unit 204 acquires information on the currently valid handle from the monitoring result recording device 300, and analyzes whether the notified handle is operable (step S610). ). The resource information analysis unit 204 notifies the monitoring result recording apparatus 300 that the received handle value is an incorrect value (for example, “NULL” or the like) or a released handle. (Step S620).

  The resource information analysis unit 204 acquires a list of variables storing handle values from the monitoring result recording apparatus 300 by assigning handles (step S630). If the value of the variable is invalid (“No” in step S640), such as the released handle value remains in the variable, the resource information analysis unit 204 notifies the monitoring result recording apparatus 300 to that effect. (Step S650).

  The resource information analysis unit 204 further checks whether there is a reference with an incorrect handle value using the inter-module reference information (step S660). That is, the resource information analysis unit 204 acquires inter-module reference information from the monitoring result recording device 300. Next, the resource information analysis unit 204 checks the validity of the function module that refers to the handle value by matching the acquired information with the current handle value and the execution location of the instruction that refers to the handle. The resource information analysis unit 204 narrows down the history with the same handle value from the execution history information recorded in the monitoring result recording device 300, and, as shown in FIG. Group as a starting point. FIG. 8 is a diagram for explaining an example of a function call flow of an execution program in the information processing apparatus according to the second embodiment of the present invention. The resource information analysis unit 204 acquires similar information regarding the handle currently in use. Then, the resource information analysis unit 204 compares the acquired information with the inter-module reference information (function call flow) grouped based on the past execution history information recorded in the monitoring result recording device 300. To find the similarity. The resource information analysis unit 204 determines whether there is a problem with reference to the handle based on the obtained similarity. As past execution history information, it is possible to store module participation information generated many times in the monitoring result recording apparatus 300 when the program is repeatedly executed in the evaluation phase. If it is determined that there is a problem with reference to the handle (“No” in step S660), the resource information analysis unit 204 notifies the monitoring result recording apparatus 300 of this together with the handle value (step S670).

  9A and 9B are diagrams illustrating an example of a function call flow of an execution program in the information processing apparatus according to the second embodiment of the present invention.

  An example will be described in which the evaluation is performed in a state where the function call flow (grouped inter-module reference information) illustrated in FIG. 8 is recorded in the monitoring result recording apparatus 300.

  When the function call shown in FIG. 9A is obtained based on the information obtained by executing the program, the resource information analysis unit 204 compares FIG. 8 with FIG. It is determined that there is similarity. At this time, the resource information analysis unit 204 determines that the handle is not illegally used.

  When the function call shown in FIG. 9B is obtained based on the information obtained by executing the program, the resource information analysis unit 204 compares FIG. 8 with FIG. It is determined that there is no similarity. At this time, the resource information analysis unit 204 determines that it is an unauthorized handle use confirmation target, and notifies the monitoring result recording apparatus 300 of the determination result.

  Next, an example of displaying on the monitoring result display device 400 based on the information recorded in the monitoring result recording device 300 will be described.

  FIG. 10 is a diagram illustrating an example of a screen that displays information about a process in the information processing apparatus according to the second embodiment of the present invention. According to FIG. 10, based on the information recorded in the monitoring result recording apparatus 300, information regarding the process is displayed in time series. For example, the monitoring result display device 400 notifies the user when an unauthorized handle use confirmation target is detected. In FIG. 10, the monitoring result display device 400 uses the “illegal” column and the “error report” column to notify that it is an unauthorized handle usage confirmation target. When the monitoring result display device 400 detects an illegal handle use confirmation target, the monitoring result display device 400 notifies the user and also allows the user to select whether to interrupt the program execution or continue the program execution. It may be possible. Further, the monitoring result display device 400 may provide a function that enables setting of interruption or continuation for each program and for each notification information.

  FIG. 11 is a diagram illustrating an example of a screen that displays information on handle variables in the information processing apparatus according to the second embodiment of the present invention. According to FIG. 11, the monitoring result display device 400 is recorded in the monitoring result recording device 300 together with the flow, the inter-module reference information referred in the determination of the illegal handle value, and the handle variable referred to in the recording range. The contents and the definition location are displayed in a list. The screen shown in FIG. 11 allows the user to confirm together the handle value, the function module that uses the handle value, and the variable that managed the handle value. As a result, the user can quickly narrow down the investigation targets necessary for program correction from the original program 101. As a result, the time and man-hours required for correction are improved, and it is expected that quality can be secured early and productivity can be improved.

  FIG. 12 is a diagram illustrating an example of a screen that displays time-series information regarding a handle variable in the information processing apparatus according to the second embodiment of the present invention. According to FIG. 12, the monitoring result display device 400 can refer to the grouped inter-module reference information and the contents of the handle values recorded in the monitoring result recording device 300 in time series. That is, the confirmation of the handle value and the operation verification of the function module and the process can be performed when the monitoring result display device 400 instructs the interruption of the program execution or after the program ends. The user can visualize and confirm the status of handle value assignment during program operation (eg, the same handle value is reassigned after being released) on the screen shown in FIG.

  FIG. 13 is a diagram illustrating an example of a screen displaying a function call flow in the information processing apparatus according to the second embodiment of the present invention. As shown in FIG. 3, the monitoring result display device 400 displays the grouped inter-module reference information recorded in the monitoring result recording device 300. The user can confirm whether or not each process using the handle is executing a process with a correct handle value when the monitoring result display apparatus 400 instructs the interruption of the program execution on the screen shown in FIG. Also, after the end of the program, the status of the handle values of multiple processes grouped together in the same way in time series order can be reproduced, and the user confirms whether the process is also executed with the correct handle values. it can. For example, even when there are not enough handles that can be acquired immediately after the same handle value is released, it is easy to determine whether an invalid handle value is used. In addition, for example, in an application that operates for a long time, it is also easy to detect an illegal use of a handle that occurs after a long period of time, which is caused by a mistake in initialization of a variable for which a handle value is set. Become.

  In this way, it is possible to obtain information on the handle usage status (secure, reference, release) during program execution without implementing it in the program, greatly increasing the work related to handles that occupy time in development work. It can be reduced and program quality can be secured. Further, since the information collected at the time of execution is stored in the monitoring result recording apparatus 300, the contents can be confirmed even after the program is executed.

  As described above, in the second embodiment, resource leak can be detected at the time of program evaluation, and as a countermeasure, information to be used as a reference when adding processing for releasing resources is stored. There is an effect that can be. Furthermore, in this embodiment, by displaying the information stored in the monitoring result recording device 300 on the monitoring result display device 400, unauthorized use is suspected, and the resource (handle) to be confirmed is notified to the user. can do.

  The reason is that the information processing apparatus according to the present embodiment adds a process at the time of program translation and records information on the handle in the monitoring result recording apparatus 300 by the process added at the time of execution of the program.

A general procedure can be adopted at present, such as a method of downloading from the Internet. In such a case, the present invention can be understood to be constituted by a code constituting the computer program or a computer-readable storage medium in which the code is recorded.
