Analysis scope, overview of main, test, generated, deployment, build, and other code.
Source Code Analysis Scope
Files includes and excluded from analyses
- 14 extensions are included in analyses: h, cpp, json, py, sh, gitignore, m4, thrift, c, md, 04, txt, yml, rl
- 2 criteria are used to exclude files from analysis:
- exclude files with path like ".*/[.][a-zA-Z0-9_]+.*" (Hidden files and folders) (12 files).
- exclude files with path like ".*[.]m4" (stuff autogenerated by autoconf - still C deps) (10 files).
- The source code folder contains 1,040 files:
- 950 files are included in analyses.
- 90 files are excluded from analyses:
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 ".*".
- 558 files match defined criteria (64,445 lines of code, 100.0% vs. main code):
- 388 *.h files (41,420 lines of code)
- 156 *.cpp files (20,664 lines of code)
- 1 *.rl files (1,033 lines of code)
- 7 *.thrift files (956 lines of code)
- 3 *.c files (309 lines of code)
- 2 *.04 files (62 lines of code)
- 1 *.py files (1 lines of code)
- " *.h" is biggest, containing 64.27% of code.
- " *.py" is smallest, containing 0% of code.
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 ".*/[Tt]est/.*".
- files with paths like ".*/test_.*".
- files with paths like ".*_test[.].*".
- 257 files match defined criteria (36,815 lines of code, 57.1% vs. main code):
- 121 *.cpp files (20,555 lines of code)
- 63 *.h files (10,572 lines of code)
- 66 *.py files (5,417 lines of code)
- 3 *.thrift files (210 lines of code)
- 4 *.sh files (61 lines of code)
- " *.cpp" is biggest, containing 55.83% of code.
- " *.sh" is smallest, containing 0.17% of code.
Build and Deployment Code
Source code used to configure or support build and deployment process.
Other Code
- The following criteria are used to filter files:
- files with paths like ".*[.]md".
- files with paths like ".*[.]json".
- files with paths like ".*/README[.][a-z0-9]+".
- files with paths like ".*/[.]gitignore".
- 114 files match defined criteria (5,498 lines of code, 8.5% vs. main code):
- 111 *.json files (5,407 lines of code)
- 3 *.md files (91 lines of code)
- " *.json" is biggest, containing 98.34% of code.
- " *.md" is smallest, containing 1.66% of code.
