Duplicated Block of Code Analysis(DBCA)

DBCA Overview

Duplicate code analysis detects duplicate blocks for code files entered for code improvement and is currently checked with a total of two types.

Type 1 (spaces, ignore comments): Ignores spaces and comments and detects duplicates.
Type 2 (ignore spaces, comments, identifiers): Ignores spaces, comments, identifiers (variable names, etc.) and detects duplicates.

The project must be open. If the project is not open, the Analysis menu is disabled.

Create an analysis accordint to Creating Analysis
In the Analysis Type window, select DBCA. Then, the Settings window will appear.

Name: is the name of this analysis.
Module: is the subject of this analysis
Duplication Type:: For Type 1, it ignores spaces and comments to detect duplicates, and in Type 2, ignores spaces, comments, and identifiers to detect duplicates.
Minimum Tokens: Enter the minimum number of tokens to check. If more tokens than this value are duplicated, it is determined as duplicate.
Ignore duplicates in a file: If selected, duplicate code within the same file is not displayed in the analysis
Include Header Files: If selected, it also displays duplicates within the header file

During the creation, uncheck the module checkbox enables user to select files instead of using all files of a module.
When non-module selection mode, Include Header Files option is disabled.
The minimum number of tokens to use for inspection can be specified within a specific range (default: 10 to 500). If necessary, you can modify a specific range through the DBCA Configuration.

ID: If the IDs are the same as duplicate code identification IDs, it means that they are duplicates.
Location: If it's a bundle, you'll see duplicates, and if it's individual code, the file name displays the start and end lines.
Included Tokens: The number of tokens that are duplicated. The number of tokens in the same ID is the same.
Lines: Indicates the number of lines that contain the number of tokens. Even if the number of tokens is the same, the number of lines may vary.
Verdict: Passed, conditionally passed, or disalted.
Etc.: The user gets a commented description in the code. However, if you want to @HKSAT code, you should start with dbca and add a description.

When you click an item in the Scan Results table, it is displayed by going to the item in the Graph Viewer and Code Viewer.

Determined on the size (lines) of duplicated block.

Criteria	Condition
Pass	the size (lines) of duplicated block < 10
Conditional Pass	10 <= the size (lines) of duplicated block < 50
Fail	50 <= the size (lines) of duplicated block

Default token size: Set the default value for the number of tokens displayed on the Default Options tab.

Partition max files: Duplicate token checks can cause out-of-memory errors if the target file is large or large. To avoid this, partitions are partitioned and inspected internally if necessary. Set the maximum number of files to fit in one partition.
Partition size in MB: Set the maximum size of one partition.

Duplicated code block is the color for duplicated code blocks in the code view.

If you experience out-of-memory errors, you can resolve them by reducing the maximum number of files in the partition and the maximum size of the partition.
