Abstract

An information processing device may comprise a log file creating unit and a first storage controlling unit. The log file creating unit may be configured to create, each time information is input, one log file that includes log information indicating an input of the information. The storage controlling unit may be configured to store, each time the one log file is created, the one log file in a storage area.

Claims

1. An information processing device comprising:

a log file creating unit configured to create, each time information is input, one log file that includes log information indicating an input of the information; and

a first storage controlling unit configured to store, each time the one log file is created, the one log file in a storage area.

2. The information processing device as in claim 1, further comprising:

an error detecting unit configured to detect an occurrence of an error caused by the input of the information;

a log file specifying unit configured to specify a first log file from the storage area in a case where an occurrence of a specific error caused by an input of specific information is detected, wherein the first log file includes specific log information indicating the input of the specific information; and

a reproducing unit configured to execute a reproduction process that reproduces an operation corresponding to the specific log information included in the first log file.

3. The information processing device as in claim 2, further comprising:

a second storage controlling unit configured to store, each time the occurrence of the error is detected, error information indicating the occurrence of the error in the storage area; and

a selection allowing unit configured to allow a user to select one error information among a plurality of error information stored in the storage area,

wherein in a case where specific error information indicating the occurrence of the specific error is selected by the user, the log file specifying unit is configured to specify the first log file.

4. The information processing device as in claim 2, wherein

the log file specifying unit is configured to specify the first log file right after the specific error is detected.

5. The information processing device as in claim 2, further comprising:

a judging unit configured to judge, in a case where the reproduction process is executed, whether the occurrence of the error is detected,

wherein, in a case where a negative judgment is made by the judging unit,

the log file specifying unit is configured to further specify from the storage area a second log file that has been created before the first log file,

the reproducing unit is configured to further execute a multiple operations reproduction process that sequentially reproduces N operations corresponding to N pieces of log information included in N log files from the second log file to the first log file in accordance with the order of log file creation of the N log files, and

the N is an integer that is equal to or more than 2.

6. The information processing device as in claim 5, wherein

the second log file is a log file that has been created directly before the first log file in the order of log file creation,

wherein, in a case where the negative judgment is made by the judging unit upon execution of the multiple operations reproduction process,

the log file specifying unit is configured to:

specify from the storage area another log file that has been created directly before the second log file in the order of log file creation; and

repeat specifying from the storage area another log file that has been created directly before the log file that has been specified the previous time until a positive judgment is made by the judging unit, and

the reproducing unit is configured to execute, each time the log file is specified by the log file specifying unit, a new multiple operations reproduction process that sequentially reproduces a plurality of operations corresponding to a plurality of pieces of log information included in a plurality of log files from the specified log file to the first log file in accordance with the order of log file creation of the plurality of log files.

7. The information processing device as in claim 5, wherein

the log file specifying unit is configured to further execute an object log file specifying process that specifies one object log file among M log files that were used in the multiple operations reproduction process for which the positive judgment has been made by the judging unit,

the M is an integer that is equal to or more than 2,

the reproducing unit is configured to further execute a partial operation reproduction process that reproduces one or more operations corresponding to one or more pieces of log information included in one or more log files excluding the object log file among the M log files.

8. The information processing device as in claim 7, wherein

the log file specifying unit is configured to sequentially specify one new object log file that has not yet been specified as the object log file among the M log files,

wherein, each time the new object log file is specified by the log file specifying unit, the reproducing unit is configured to further reproduce:

in a case where the positive judgment is made by the judging unit upon a previous execution of the partial operation reproduction process, one or more operations corresponding to one or more pieces of log information included in one or more log files excluding the specified new object log file among log files which were used in the previous execution of the partial operation reproduction process; and

in a case where the negative judgment is made by the judging unit upon the previous execution of the partial operation reproduction process, one or more operations corresponding to one or more pieces of log information included in one or more log files excluding the specified new object log file among the log files which were used in the previous execution of the partial operation of the reproduction process, the one or more log files including an object log file that has been excluded the previous time.

9. The information processing device as in claim 2, further comprising:

an image information data creating unit configured to create image information data that specifies image data in a case where the inputted information is the image data,

a dummy image data creating unit configured to create dummy image data from the image information data,

wherein, in a case where the image data is input, the log file creating unit is configured to create a log file that includes a predetermined log information having the image information data, and

in a case where an operation corresponding to the predetermined log information is to be reproduced, the reproducing unit is configured to reproduce the operation corresponding to the predetermined log information by using the dummy image data created from the image information data.
