Source Code Analysis Scope

Files includes and excluded from analyses

txt

clang-format

gitmodules

11 extensions are included in analyses: cc, h, md, in, txt, yaml, c, gitignore, clang-format, gitmodules, html
3 criteria are used to exclude files from analysis:

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).

The source code folder contains 153 files:

143 files are included in analyses.
10 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.

104 files

31 files

8 files

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 ".*".

104 files match defined criteria (14,320 LOC, 100.0% vs. main code):

45 *.cc files (11,045 LOC)
56 *.h files (2,831 LOC)
1 *.html files (420 LOC)
2 *.in files (24 LOC)

" *.cc" is biggest, containing 77.13% of LOC.
" *.in" is smallest, containing 0.17% 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 ".*_test[.].*".

31 files match defined criteria (7,171 LOC, 50.1% vs. main code):

30 *.cc files (6,842 LOC)
1 *.c files (329 LOC)

" *.cc" is biggest, containing 95.41% of LOC.
" *.c" is smallest, containing 4.59% of LOC.

8 files match defined criteria (1,316 LOC, 9.2% vs. main code):

7 *.md files (880 LOC)
1 *.txt files (436 LOC)

" *.md" is biggest, containing 66.87% of LOC.
" *.txt" is smallest, containing 33.13% of LOC.

Analyzers

Info about analyzers used for source code examinations.

*.cc files are analyzed with CppAnalyzer:

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

Advanced heuristic dependency analysis

*.h files are analyzed with CppAnalyzer:

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

Advanced heuristic dependency analysis

*.html files are analyzed with HtmlAnalyzer:

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)
