📦 FreeBSD CVS Archive (C/C++)
Dataset Summary
FreeBSD CVS Archive (C/C++) is a large-scale dataset of source code extracted from the historical FreeBSD CVS repository. The dataset focuses on C and C++ source files, providing structured samples suitable for code modeling, analysis, and benchmarking.
Each sample includes:
- the dataset source
- commit year
- extracted code content
- token count (computed using GPT tokenizer)
This dataset is designed for:
- code language modeling
- software evolution analysis
- code understanding and generation
- benchmarking LLMs on real-world system code
Dataset Structure
Each record follows a simple JSONL format:
{
"Source": "freebsd-cvs-archive",
"Date": 2003,
"Text": "... C/C++ source code ...",
"Token_count": 512
}
Fields
Source: Name of the dataset Date: Year extracted from CVS revision metadata Text: Raw C/C++ code snippet Token_count: Number of tokens computed using tiktoken (cl100k_base)
Source Data
The dataset is derived from:
FreeBSD CVS archive (historical version control system)
Processing
Processing Pipeline
The dataset was constructed using the following steps:
Parse CVS revision files Extract revision metadata (commit date → year) Extract text blocks (code sections between CVS delimiters) Filter samples (remove empty or short entries) Keep only C/C++ code Compute token counts using tiktoken Split into fixed-size JSONL shards
