Source Code Overview

Analysis scope, overview of main, test, generated, deployment, build, and other code.

Source Code Analysis Scope
Files includes and excluded from analyses
mod
txt
  • 10 extensions are included in analyses: go, json, sh, rb, md, mod, ps1, gitignore, txt, yml
  • 4 criteria are used to exclude files from analysis:
    • exclude files with path like ".*/bin/.*" (Binaries for distribution) (6 files).
    • exclude files with path like ".*/[.][a-zA-Z0-9_]+.*" (Hidden files and folders) (3 files).
    • exclude files with path like ".*/git[-]history[.]txt" (Git history) (1 file).
    • exclude files with path like ".*/git[-][a-zA-Z0-9_]+[.]txt" (Git data exports for sokrates analyses) (0 files).
Overview of Analyzed Files
Basic stats on analyzed files
Intro
For analysis purposes we separate files in scope into several categories: main, test, generated, deployment and build, and other.

  • The main category contains all manually created source code files that are being used in the production.
  • Files in the main category are used as input for other analyses: logical decomposition, concerns, duplication, file size, unit size, and conditional complexity.
  • Test source code files are used only for testing of the product. These files are normally not deployed to production.
  • Build and deployment source code files are used to configure or support build and deployment process.
  • Generated source code files are automatically generated files that have not been manually changed after generation.
  • While a source code folder may contain a number of files, we are primarily interested in the source code files that are being written and maintained by developers.
  • Files containing binaries, documentation, or third-party libraries, for instance, are excluded from analysis. The exception are third-party libraries that have been changed by developers.

Main Code
All manually created or maintained source code that defines logic of the product that is run in a production environment.

  • The following criteria are used to filter files:
    • files with paths like ".*".
  • 44 files match defined criteria (3,305 lines of code, 100.0% vs. main code). All matches are in *.go files.


*.go3305 LOC (100%) 44 files
Test Code
Used only for testing of the product. Normally not deployed in a production environment.

  • The following criteria are used to filter files:
    • files with paths like ".*_test[.].*".
  • 11 files match defined criteria (481 lines of code, 14.6% vs. main code). All matches are in *.go files.

    • files with paths like ".*[.]git[a-z]+".
    • files with paths like ".*/[.]gitignore".
    • files with paths like ".*[.]sh".
  • 6 files match defined criteria (46 lines of code, 1.4% vs. main code). All matches are in *.sh files.

Analyzers
Info about analyzers used for source code examinations.
  • *.go files are analyzed with GoLangAnalyzer:
    • All basic standard analyses supported (source code overview, duplication, file size, concerns, findings, metrics, controls)
    • Advanced code cleaning (empty lines and comments removed for LOC calculations, additional cleaning for duplication calculations)
    • Unit size analysis
    • Conditional complexity analysis
    • Basic heuristic dependency analysis
