Known LGPL Dependencies¶
While RustyBT follows an Apache 2.0/MIT-only dependency policy, the following LGPL dependencies currently exist as transitive dependencies:
| Package | License | Type | Source | Status |
|---|---|---|---|---|
frozendict |
LGPL v3 | Production | Via yfinance (Yahoo Finance data) |
Tracked for replacement |
chardet |
LGPL | Development | Via tox (testing tool) |
Tracked for replacement |
Legal Status: LGPL allows use as a dynamically-linked library without GPL license contamination. RustyBT's Apache 2.0 license remains unaffected.
Mitigation Plans:
- frozendict: Evaluating alternative data providers or forking yfinance with MIT-licensed replacement
- chardet: Considering migration from tox to modern alternatives (nox, hatch)
