What files do "ctu_connections" actually contain?

[sahil-time]

Hi folks,

• I was checking the "ctu_connections" folder, and I'm not sure how particular files are chosen for a TU
• For instance, I see some files that are directly needed for the current translation unit, and some files that are indirectly needed.
• How does CodeChecker decide this?

Thanks,

It's not CodeChecker's decision, we only read the list of files the analyser actively looked into during an executed analysis:

codechecker/analyzer/codechecker_analyzer/analysis_manager.py

Lines 461 to 482 in d2b1197

	"""

	if source_analyzer.ANALYZER_NAME != ClangSA.ANALYZER_NAME:
	return
	involved_files = set()
	involved_files.update(source_analyzer.get_analyzer_mentioned_files(

	involved_files.update(source_analyzer.get_analyzer_mentioned_files(
	result_handler.analyzer_stderr))
	out = os.path.join(output_dir, result_handler.analyzer_action_str)
	if involved_files:
	with open(out, 'w', encoding='utf-8', errors='ignore') as f:
