Abstract

In an information processing apparatus, a program execution section executes a program, and in the stage of execution of a log acquisition command, acquires the value of a variable set in the log acquisition command. A trace log generation section generates a trace log including identification information on a file set in the log acquisition command, version number on a source code, and the acquired value of the variable, and stores the trace log in a storage device. A source code acquisition section acquires a source code corresponding to a combination of the identification information and the version number, based on the trace log. A character string addition section extracts a character string related to the value of the variable included in the trace code, from the acquired source code, adds the extracted character string to the trace log, and stores the trace log in a storage device.

Claims

1. An information processing apparatus including one or more processors configured to perform a procedure, the procedure comprising:

executing a program including a log acquisition command having set therein identification information on a file describing a source code of the program, version number information on the source code, and a variable, and acquiring a value of the variable set in the log acquisition command when the log acquisition command has reached a stage of execution; and

generating a trace log including the identification information on the file and the version number information set in the log acquisition command in the stage of execution, and the value of the acquired variable, and storing the trace log in a storage device.

2. The information processing apparatus according to claim 1, wherein a line number of a line describing the log acquisition command in the source code is set in the log acquisition command, and

wherein the generating generates a trace log including the line number included in the log acquisition command in the stage of execution.

3. An information processing apparatus including one or more processors configured to perform a procedure, the procedure comprising:

acquiring, based on a trace log including identification information on a file describing a source code of a program, version number information on the source code, and a value of a variable, the source code corresponding to a combination of the identification information on the file and the version number information; and

extracting from the source code acquired based on the trace log, a character string related to the trace log, adding the extracted character string to the trace log, and storing the trace log having the character string added thereto, in a storage device.

4. The information processing apparatus according to claim 3, wherein the identification information on the file included in the trace log is a code uniquely associated with the file describing the source code, and

wherein the acquiring determines a file name corresponding to the code included in the trace log, based on management information in which is registered a correspondence between a file name of the file describing the source code and the code uniquely associated with the file, and acquires the source code from a file corresponding to a combination of the file name and the version number information included in the trace log.

5. The information processing apparatus according to claim 4, wherein the code uniquely associated with the file has an amount of data smaller than an amount of data of the file name of the file.

6. The information processing apparatus according to claim 4, wherein the extracting adds the file name corresponding to the code included in the trace log, to the trace log.

7. The information processing apparatus according to claim 3, wherein the trace log includes a line number of a line describing a log acquisition command in the source code, and

wherein the extracting extracts a character string related to the trace log from the log acquisition command described on the line, which is indicated by the line number included in the trace log, in the source code acquired based on the trace log.

8. The information processing apparatus according to claim 3, wherein the extracting extracts a character string related to a value of a variable included in the trace log.

9. The information processing apparatus according to claim 3, wherein the extracting stores, in the storage device, a file describing contents of the trace log having the character string extracted from the source code added thereto, in a markup language.

10. The information processing apparatus according to claim 9, wherein the extracting adds a description for highlighting the value of the variable in the trace log having the character string extracted from the source code added thereto, to the file describing the contents of the trace log having the character string extracted from the source code added thereto.

11. The information processing apparatus according to claim 9, wherein the extracting adds a hyperlink linking to the source code, to the trace log having the character string extracted from the source code added thereto.

12. A method of acquiring a trace log, the method comprising:

a first procedure executed by a first information processing apparatus, comprising;

executing a program including a log acquisition command having set therein identification information on a file describing a source code of the program, version number information on the source code, and a variable;

acquiring, when the log acquisition command has reached a stage of execution, a value of the variable set in the log acquisition command in the stage of execution;

generating a trace log including the identification information on the file and the version number information set in the log acquisition command in the stage of execution, and the acquired value of the variable; and

storing the generated trace log in a first storage device; and

a second procedure executed by a second information processing apparatus, comprising;

acquiring, based on the trace log stored in the first storage device, a source code corresponding to a combination of the identification information on the file and the version number information included in the trace log;

extracting from the source code acquired based on the trace log, a character string related to the trace log, and adding the extracted character string to the trace log; and

storing the trace log having the character string added thereto, in a second storage device.

13. The trace log-acquiring method according to claim 12, further comprising:

a third procedure executed by a third processing apparatus, comprising;

setting in a log acquisition command included in the source code of the program, a code uniquely associated with a file name of a file describing the source code, as identification information on the file, and setting version number information on the source code in the log acquisition command; and

storing management information including the file name of the file describing the source code, the code corresponding to the file name, and the version number information on the source code, in a manner associated with the file describing the source code, in a third storage device,

wherein the first procedure further comprises executing a program including the log acquisition command having the code uniquely associated with the file name set as the identification information on the file, and

wherein the second procedure further comprises determining the file name corresponding to the code included in the trace log, based on the management information stored in the third storage device, and acquiring the source code from the file associated with the management information including the file name and the version number information included in the trace log.
