Description

Support huggingface-hub 2.x (Fixes #742). Hub 2.0 moved from httpx to httpx2; fastembed's _hf_transport_errors() shim already imports the HTTP layer via huggingface_hub.utils.httpx (available since hub 1.30), so no production-code changes were needed. Every hub API fastembed uses (snapshot_download, model_info, list_repo_tree, repo_folder_name, RepoFile, utils helpers, constants) was verified present and signature-compatible in 2.0.0 with live smoke tests.

Note: tokenizers (a fastembed dependency) still pins huggingface-hub<2.0 in its latest release, so end users will only resolve hub 2.0 once tokenizers ships a compatible release — outside this repo's control.

Changes Made

• pyproject.toml: huggingface-hub = ">=0.20,<2.0" → ">=0.20,<3.0".
• tests/test_model_management.py: 3 new fully-offline tests — hub import-surface resolution, transport-error shim coverage, and a mocked online download flow (metadata collect/verify).

Testing

• Live smoke tests under huggingface-hub 2.0.0: model_info → sha, list_repo_tree → 16 entries with working .path/.size/.blob_id, snapshot_download of config.json — all pass.
• pytest tests/test_model_management.py tests/test_common.py: 11 passed.
• ruff check and ruff format --check: clean on both changed files.
• Model-download-dependent suites (test_preprocessor_utils, test_postprocess, test_parallel_processor) aren't runnable in this sandbox (they pull weights from huggingface.co); unrelated to this change.

📝 Walkthrough

Walkthrough

The Hugging Face Hub dependency upper bound changes from below 2.0 to below 3.0. New offline tests check Hub imports and RepoFile fields, transport-error handling, and metadata written during a mocked download.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Merge Risk: 🟡 Moderate · up to 1f598

Users cannot install Hub 2.x with the project’s current dependency requirements. Resolve the tokenizers constraint or defer the expanded Hub range before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 03da3

The current locked installation remains on Hub 1.x, and this change does not widen which models or files the application requests. No introduced security issue was identified, but behavior under future Hub 2.x installations is not fully established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — Potential new-version exposure is confined to installations that resolve Hub 2.x and use the existing model-download integration; the committed locked installation does not select that version.

Trust Boundaries and Controls

• observed — Hub repository listings supply file metadata used by the existing cache collector and verifier. The successful mocked test checks that the Hub-style file object exposes the fields those consumers read; it does not establish failure or adversarial-response behavior.

Resilience and Maintainability Implications

• observed — The existing code lists files at an explicit revision but does not explicitly pass that revision to snapshot_download. The new mock keeps those operations consistent and does not test a repository change between them; this is a pre-existing invariant gap, not a demonstrated regression.

Hardening Proposals

• proposed — For stronger cache-to-repository binding, pass the selected revision through snapshot download and exercise revision changes and interrupted downloads under an actual Hub 2.x resolution.

Review comments at @pyproject.toml:
- Line 31: Update the huggingface-hub constraint and dependency lock together so
the locked tokenizers release supports Hub 2.x: select a compatible tokenizers
release and regenerate poetry.lock, or keep huggingface-hub below 2.0 until one
is available.

Review comments at @tests/test_model_management.py:
- Around line 170-174: Update the transport-error assertion in the test around
_hf_transport_errors() to check huggingface_hub.utils.httpx.TransportError when
that module is available, including verifying it is in _HF_DOWNLOAD_ERRORS.
Retain the direct-httpx exception assertion as the fallback for older Hub
versions.
