Source Code Analysis Scope

Files includes and excluded from analyses

txt

mod

9 extensions are included in analyses: go, yaml, md, sh, py, json, txt, mod, gitignore
3 criteria are used to exclude files from analysis:

exclude files with path like ".*/[.][a-zA-Z0-9_]+.*" (Hidden files and folders) (2 files).
exclude files with path like ".*/sokrates_.*?[.]json" (Sokrates conventions and configurations) (1 file).
exclude files with path like ".*/docs/.*" (Documentation) (13 files).

The source code folder contains 219 files:

186 files are included in analyses.
33 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 ".*".

61 files match defined criteria (5,274 LOC, 100.0% vs. main code):

36 *.go files (4,330 LOC)
24 *.yaml files (798 LOC)
1 *.py files (146 LOC)

" *.go" is biggest, containing 82.1% of LOC.
" *.py" is smallest, containing 2.77% of LOC.

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 ".*_tests[.].*".
files with paths like ".*/[Tt]est/.*".
files with paths like ".*_test[.].*".
files with paths like ".*/e2e/.*".
files with paths like ".*/[Ss]pecs/.*".

52 files match defined criteria (11,583 LOC, 219.6% vs. main code):

44 *.go files (11,437 LOC)
3 *.sh files (112 LOC)
3 *.yaml files (32 LOC)
2 *.py files (2 LOC)

" *.go" is biggest, containing 98.74% of LOC.
" *.py" is smallest, containing 0.02% of LOC.

Build and Deployment Code

Source code used to configure or support build and deployment process.

The following criteria are used to filter files:

files with paths like ".*[.]sh".
files with paths like ".*[.]git[a-z]+".
files with paths like ".*/[.]gitignore".

12 files match defined criteria (501 LOC, 9.5% vs. main code). All matches are in *.sh files.

8 *.py files (340 LOC)
2 *.mod files (295 LOC)
1 *.sh files (101 LOC)
7 *.txt files (89 LOC)
8 *.json files (89 LOC)

" *.yaml" is biggest, containing 51.41% of LOC.

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

*.yaml files are analyzed with YamlAnalyzer:

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)

No unit size analysis

No conditional complexity analysis

No dependency analysis

*.py files are analyzed with PythonAnalyzer:

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
