Source Code Analysis Scope
Files includes and excluded from analyses
txt

gitmodules
  • 23 extensions are included in analyses: py, h, cc, js, c, rst, txt, json, pyi, md, html, css, cpp, cmake, sh, yaml, bat, yml, dockerignore, cfg, gitignore, clang-format, gitmodules
  • 3 criteria are used to exclude files from analysis:
    • exclude files with path like ".*/bin/.*" (Binaries for distribution) (7 files).
    • exclude files with path like ".*/[.][a-zA-Z0-9_]+.*" (Hidden files and folders) (6 files).
    • exclude files with path like ".*/(3rd|[Tt]hird)[-_]?[Pp]arty/.*" (Dependencies) (88 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.
