Closes #105not as a full Poetry→uv migration, but as a deliberate hybrid: stay on Poetry as primary, add best-effort uv support for install/use.

Why this scope (not full migration)

After deep evaluation of the ecosystem state (full thread on #105 and this PR):

  • Snyk's GH App doesn't yet support uv.lock (snyk-python-plugin#251 open). Workarounds either break snyk parsing ([project] + [tool.poetry.dependencies] coexistence → "Failed to detect issues") or create dual-lockfile drift risk with auto-security-patching bots.
  • Maintainer has many repos; per-repo migration burden + ecosystem friction outweighs the speed gain today.
  • uv works fine for install/use from this repo via git+https; full migration can land later when the ecosystem catches up.

Other famous uv adopters (Pydantic, FastAPI, httpx) don't use snyk — they rely on CodeQL + dependabot. Snyk parity for uv is a real gap.

What this PR does

Security: bump vulnerable dep floors

Snyk scans the constraint lower bound when no specific version is locked. Bumped to match poetry.lock resolution:

  • click ^8.3.3 — fixes SNYK-PYTHON-CLICK-16347201 (HIGH, command injection in click.edit() filename param). Was ^8.2.1.
  • aiohttp ^3.13.5 — fixes multiple HIGH vulns (SSRF on Windows static handler, memory exhaustion in multipart/Request.post/ZLibDecompressor, request smuggling). Was ^3.12.0.
  • aiodns ^3.6.1, attrs >=26.1.0,<27.0.0, maxminddb ^2.8.2, pyyaml ^6.0.3, pytest ^8.4.2, pytest-mock ^3.15.1, pytest-cov ^6.3.0.
  • Dropped pytest-runner (deprecated, unused).
  • Added attrs upper bound per coderabbit review.

uv install/use compatibility

Documentation only — uv works "for free" because poetry-core 2.x synthesizes PEP 621 metadata at build time:

  • pip install git+https://github.com/bluet/proxybroker2.git@<tag> (existing)
  • uv pip install git+https://github.com/bluet/proxybroker2.git@<tag> (added, equivalent)
  • uv add "proxybroker2 @ git+https://github.com/bluet/proxybroker2.git@<tag>" (added, for uv-managed projects)

PyPI install warning expanded

Per #186 and pypi/support#10315, both proxybroker AND proxybroker2 PyPI names are squatted by unauthorized publishers. README now states clearly: install only from this repo, never from PyPI.

Contributor docs

Poetry remains canonical (poetry install / poetry run pytest). uv supported as best-effort alternative for local dev. uv.lock is NOT committed — avoids drift with the authoritative poetry.lock.

What this PR doesn't do (deferred)

  • Full Poetry → uv migration (wait for snyk uv.lock support)
  • Triaging the 30 open Dependabot alerts (separate PR after this lands)

After-merge action for maintainer

Re-add the build matrix check to branch protection — was temporarily removed earlier in this PR's iteration. Old name was build (3.14, 2.3.2); matrix is unchanged so the same name still applies after this PR. The Snyk check (security/snyk (bluet)) should pass on master once poetry.lock is back.

Verification

Check Result
uvx poetry install ✓ succeeds with bumped deps
poetry run pytest -x ✓ 293/293 pass
poetry build ✓ wheel + sdist
docker build + docker run --version
uv pip install <source> ✓ poetry-core builds, uv installs, proxybroker --version returns 2.0.0b3

Issue #105 has been open since 2022, originally about consolidating onto
Poetry-only. With uv 0.11.13 mature and 10-30× faster than Poetry, the
calculus shifted. Migrate the entire dev/CI/Docker toolchain to uv in one
pass.

Why uv now:
- 10-30× faster resolve (matters most across the Py 3.10-3.14 CI matrix)
- PEP 621 [project] + PEP 735 [dependency-groups] native (standards-track,
  not Poetry-specific)
- Single binary replaces Poetry's role for install/lock/sync/run
- Build backend stays poetry-core>=2.1.3; poetry-core 2.x reads PEP 621
  natively, so PyPI publish (`python -m build`) keeps working unchanged

Migration scope (one-pass per the matrix-audit-fix-in-one-pass methodology
from PR #225 / PR #210):

pyproject.toml
- [tool.poetry.*] sections → PEP 621 [project] + [dependency-groups.dev]
- caret constraints (^X.Y.Z) → PEP 440 explicit ranges (>=X.Y.Z,<(X+1).0.0)
- ruff added to dev group (was previously installed ad-hoc in CI)
- pytest-runner dropped (deprecated, no longer needed)

Lockfile transition
- Generated fresh uv.lock (33 packages resolved in 642ms)
- Verified resolution parity vs poetry.lock: no major-version drift on
  any direct dep; only minor/patch bumps within constraints
- Deleted poetry.lock; removed uv.lock from .gitignore

CI workflows
- python-test-versions.yml: snok/install-poetry → astral-sh/setup-uv@v8.1.0
  (SHA-pinned), poetry install → `uv sync --locked --dev`, all `poetry run`
  → `uv run`. Added `enable-cache: true`.
- py-to-exe.yml: same pattern. pyinstaller installed via `uv pip install`
  (build tooling, not a project dep).
- python-publish.yml: unchanged (already uses `python -m build`).

Dockerfile
- pip install poetry → COPY --from=ghcr.io/astral-sh/uv:0.11.13 (tag+digest
  pinned, same pattern as the python:3.14-slim base).
- Multi-stage layout: deps layer (`uv sync --no-install-project --no-dev`)
  separated from project layer for better cache hit rate.
- ENTRYPOINT keeps `python -m proxybroker` via PATH=/app/.venv/bin.

Docs
- README "Development Setup": Poetry → uv (with `curl install uv` snippet
  for new contributors); Development Tools list updated.
- CLAUDE.md "Setup" + "Known Quirks" sections: Poetry → uv; clarified that
  poetry-core remains the build backend.

Verification (all green locally before push):
- uv lock: 33 packages, 642ms
- uv sync --locked --dev: succeeds
- uv run pytest -x: 293/293 passing
- uv run ruff check . + ruff format --check .: clean
- python -m build: sdist + wheel both build (validates poetry-core 2.x
  reading PEP 621 metadata)
- docker build + docker run --rm proxybroker2:uv-test --help: image
  builds in ~4s, CLI invokes correctly

Out of scope:
- docs/requirements.txt: used directly by ReadTheDocs, not part of dev
  workflow. Left as-is.
- MANIFEST.in: setuptools artifact, no change.
- .pre-commit-config.yaml: uses ruff/bandit standalone, no change.

Code Review

This pull request migrates the project from Poetry to uv for package management, updating the Dockerfile, development documentation, and pyproject.toml to use PEP 621 and PEP 735 standards. Feedback points out several version hallucinations for dependencies like attrs, ruff, and the uv Docker image that would lead to build failures. Additionally, a redundant apt-get upgrade command was noted in the Dockerfile's builder stage.

Walkthrough

Migrates the repository from Poetry to uv: pyproject moved to PEP 621, lockfile and ignore rules updated, CI and PyInstaller workflows use uv, Docker build copies uv binaries and runs two-stage syncs, pre-commit exports requirements.txt, and docs updated for uv commands.

Changes

Dependency Toolchain Migration from Poetry to uv

Layer / File(s) Summary
Project Metadata Restructure
pyproject.toml
Converted from Poetry sections to PEP 621 [project]; dependencies re-declared; dev deps moved to [dependency-groups].dev; console script moved to [project.scripts]; build-system preserved.
Lock File & Ignore Rules
.gitignore
Stopped ignoring uv.lock; added ignore entries for security-scan artifacts matching *-report.json and *-stderr.txt.
Container Build & Runtime
Dockerfile
Copies uv/uvx binaries from pinned image; replaces PIP env vars with uv env vars; installs build deps; performs lock-first uv sync then source sync; adds .venv/bin to PATH; retains python -m proxybroker entrypoint.
Test & Lint Workflow
.github/workflows/python-test-versions.yml
Removed poetry-version axis; replaced Poetry setup with astral-sh/setup-uv and uv sync --locked --dev pinned to matrix Python; run ruff and pytest via uv run (same flags/coverage).
Executable Build Workflow
.github/workflows/py-to-exe.yml
Replaced Poetry steps with actions/setup-python + uv install; dependencies synced with uv sync --locked --python ...; pyinstaller installed via uv pip install; build invoked with uv run pyinstaller.
Pre-commit Hook
.pre-commit-config.yaml
Added local hook uv-export-requirements to run uv export and regenerate requirements.txt when uv.lock or pyproject.toml change.
Developer Documentation
README.md, CLAUDE.md
Updated setup, testing, lint, and tooling instructions to use uv sync and uv run; noted poetry-core remains build backend and requirements.txt is generated from uv.lock.
Autogenerated Requirements
requirements.txt
Added requirements.txt exported from uv.lock (non-dev, no hashes) with pinned versions and environment markers.

Comment thread pyproject.toml Outdated
Snyk's Python plugin doesn't yet support uv.lock files (snyk-python-plugin
#251 still open as of 2026-05-11), so the snyk PR check errors when
poetry.lock disappears in the migration. Generate requirements.txt from
uv.lock as a snyk-readable manifest until upstream support lands.

- requirements.txt: generated via `uv export --format requirements-txt
  --no-dev --no-emit-project`. Includes hashes; ~954 lines.
- .pre-commit-config.yaml: add a local hook that auto-regenerates the file
  whenever uv.lock or pyproject.toml changes. Uses `language: system` so
  it runs against whatever uv is on PATH.
- CLAUDE.md: document the workaround and the upstream issue, with a note
  to remove this once Snyk ships uv support.

Tradeoff: one auto-generated file in the repo with a clear "don't edit
by hand" mechanism. Better than carrying poetry.lock alongside uv.lock
(which would defeat the migration's purpose) or making snyk a non-blocking
check (security regression).

Snyk's pip parser handles the simpler `pkg==version` format more
reliably than the hashed format. Switch the export and the pre-commit
hook accordingly. Cuts the file from ~954 lines to ~53.

Comment thread requirements.txt Outdated
CI failure on PR #230 commit 1558779: build (3.12) failed because the
runner used Python 3.12.3 (pre-installed on ubuntu-latest), not 3.12.11+.
Two tests assert RFC 5952 IPv4-mapped IPv6 string format
(`::ffff:192.0.2.1`), which Python only adopted in 3.12.4 (bpo-119891).

Root cause: setup-uv's `python-version: "3.12"` doesn't install the
LATEST 3.12 patch — it picks up whatever Python is already on PATH (the
runner's older pre-installed version).

Fix: install Python via `actions/setup-python` first (always picks the
latest patch for the requested minor), then run setup-uv WITHOUT the
`python-version` input. Pass `--python ${{ matrix.python-version }}` to
`uv sync` to pin uv to the version setup-python provided.

Same fix applied to py-to-exe.yml for consistency.

CI status update on commit `51ed1f3`:

All build/test/security checks pass except snyk.

Snyk error explanation: Snyk's Python plugin doesn't yet support `uv.lock` (snyk-python-plugin#251 still open). I committed a generated `requirements.txt` (auto-regenerated by a pre-commit hook from `uv.lock`) as a snyk-readable manifest, but the snyk PR check still errors across 4 commits — the snyk app likely has the project configured to monitor `poetry.lock` specifically.

The fix requires a one-time snyk org settings change I can't make from the repo:

  1. Go to app.snyk.io/org/bluet → proxybroker2 project
  2. Update "monitored files" to include `requirements.txt` (or remove the explicit `poetry.lock` and let snyk auto-detect)
  3. Trigger a re-scan

Other security gates (CodeQL, SonarCloud, fossa, fossabot, semgrep) all green and unaffected.

Alternative: keep `poetry.lock` alongside `uv.lock` during the transition. Doubles maintenance but avoids touching snyk config.

bluet and others added 5 commits May 12, 2026 06:18
Earlier `uv export ... > requirements.txt` shell-redirect captured uv's
"Resolved N packages in Xms" status line into the file. Use `--quiet`
plus `--output-file` so only the actual requirements end up in the file.

Match the same flags in the pre-commit hook so future regenerations stay
clean.

…nt floor

Snyk preview (now enabled) parses pyproject.toml's [project.dependencies]
correctly and flagged click@8.2.1 — the constraint `>=8.2.1` lets a
vulnerable lower-bound version satisfy the requirement, even though
uv.lock pins click==8.3.3.

Audit of all dep lower bounds against snyk's vulnerability database:

- click 8.2.1 → SNYK-PYTHON-CLICK-16347201, HIGH severity, command
  injection in click.edit() filename param. Fixed in 8.3.3.
- aiohttp 3.12.0 → multiple HIGH vulns (SSRF on Windows static handler,
  memory exhaustion in multipart/Request.post/ZLibDecompressor, request
  smuggling). Fixed in 3.13.4+.
- aiodns, attrs, maxminddb, cachetools, pyyaml: no known vulns at floor,
  bumped anyway for consistency with uv.lock.

Strategy: align all dep lower-bounds with what uv.lock currently
resolves. That's what CI tests against, so it's the right floor — also
eliminates "lower-bound vuln" false positives from constraint-only
scanners going forward.

- aiohttp: 3.12.0 → 3.13.5
- aiodns: 3.4.0 → 3.6.1
- attrs: 25.3.0 → 26.1.0
- maxminddb: 2.7.0 → 2.8.2
- cachetools: 5.5.2 (no change)
- click: 8.2.1 → 8.3.3
- pyyaml: 6.0.2 → 6.0.3
- pytest (dev): 8.3.5 → 8.4.2
- pytest-mock (dev): 3.14.0 → 3.15.1
- pytest-cov (dev): 6.1.1 → 6.3.0

293/293 tests pass with bumped constraints.

Co-Authored-By: Claude <noreply@anthropic.com>
Snyk's GitHub PR app integration uses the legacy poetry parser even when
the org has "uv preview" enabled — preview is CLI-only per their docs:
https://docs.snyk.io/supported-languages/supported-languages-list/python/cli-support-for-uv

Without [tool.poetry.dependencies] in pyproject.toml the snyk PR check
fails with "pyproject.toml error Failed to detect issues" and never falls
through to scan requirements.txt or uv.lock. The shim mirrors the
just-bumped (and verified vuln-free) [project.dependencies] versions so
snyk's legacy parser succeeds without finding any vulns at the constraint
floor.

Pre-commit hook still keeps requirements.txt in sync for redundancy.

Will revert this whole [tool.poetry.dependencies] block once snyk's PR
app integration uses uv preview natively (snyk-python-plugin#251).

Build verified: `python -m build` produces wheel + sdist.
Tests verified: 293/293 pass.

Co-Authored-By: Claude <noreply@anthropic.com>
Triaged comments from coderabbit, gemini-code-assist, codex, and the
ongoing snyk investigation. Three valid actionable items + one false
positive class to flag.

1. Snyk: [tool.poetry] block was incomplete — Poetry requires
   name/version/description/authors as required fields. Without them,
   snyk's poetry parser rejects the block as invalid and reports
   "pyproject.toml error Failed to detect issues" before even getting
   to dependencies. Add the required identity fields, mirroring values
   from [project] above. poetry-core 2.x prefers [project] when both
   are present, so this duplication doesn't affect builds. Verified:
   `python -m build` produces wheel + sdist correctly.

2. coderabbit: attrs missing upper bound for consistency with other
   deps. Added `<27.0.0`. attrs uses year-based major versioning, so
   this caps at the next year boundary — same pattern as other caret
   constraints. Mirrored in [tool.poetry.dependencies] shim.

3. gemini-code-assist (medium) + coderabbit (nitpick): Dockerfile
   builder stage had redundant `apt-get upgrade -y` (already done in
   base stage) and missing `--no-install-recommends`. Removed the
   redundant upgrade and added the flag. Verified: `docker build` +
   `docker run --version` both work.

4. gemini-code-assist (3x "hallucination" comments on attrs 26.1.0,
   ruff 0.15.12, uv 0.11.13): false positives. All three are real,
   current package versions (verified via PyPI / GitHub releases /
   ghcr.io image registry). Gemini's training data appears to predate
   these releases; will reply on the comments rather than change code.

5. codex requirements.txt comment was already addressed in commit
   7aa59b5 by adding `--quiet` to the export command — now generates
   clean output without the resolver status line.

293/293 tests pass. Docker image builds in ~4s. Wheel + sdist build.

…e error

Backwards reasoning: at commit 51ed1f3 (NO [tool.poetry.dependencies])
snyk successfully parsed [project.dependencies] via its uv preview AND
reported the click@8.2.1 vuln. Snyk CAN read PEP 621 deps with preview
enabled; the parser was working.

When I added [tool.poetry.dependencies] alongside in commit 283154b,
snyk started erroring with "Failed to detect issues" — presumably
because two competing dep declarations (PEP 621 vs Poetry-style)
confuse the parser. The shim was the cause, not the fix.

Now that the click bump in commit 28405e6 already cleared the only
real vuln snyk had flagged, the simpler config (just [project], no
shim) should make snyk happy. Keeping a comment explaining why the
shim is deliberately absent so a future contributor doesn't re-add it.

Build verified (wheel + sdist), 293/293 tests pass.

#105)

Decision after deep evaluation: stay on Poetry as primary, add best-effort
uv support for install/use. Closes #105 not as a full migration but as a
deliberate "support both, canonical = Poetry" position.

Why not full uv migration:
- Snyk's GH App doesn't yet support uv.lock (snyk-python-plugin#251 open).
  Workarounds either break snyk parsing or create dual-lockfile drift risk
  with auto-security-patching bots (dependabot, snyk auto-fix PRs).
- Maintainer has many repos; per-repo migration burden + ecosystem
  friction outweighs the speed gain today.
- uv works fine for install/use from this repo via git+https; full
  migration can land later when the ecosystem catches up.

Changes:

1. Bump dependency lower-bounds to clear known vulnerabilities at the
   constraint floor (snyk scans the lower bound when no specific version
   is locked):
   - click ^8.3.3 fixes SNYK-PYTHON-CLICK-16347201 (HIGH, command injection
     in click.edit() filename param). Was ^8.2.1.
   - aiohttp ^3.13.5 fixes multiple HIGH vulns (SSRF on Windows static
     handler, memory exhaustion in multipart/Request.post/ZLibDecompressor,
     request smuggling). Was ^3.12.0.
   - Other deps bumped to match poetry.lock current resolution: aiodns
     ^3.6.1, attrs >=26.1.0,<27.0.0, maxminddb ^2.8.2, pyyaml ^6.0.3,
     pytest ^8.4.2, pytest-mock ^3.15.1, pytest-cov ^6.3.0.
   - Dropped pytest-runner (deprecated, unused).
   - Added attrs upper bound per coderabbit review.

2. Regenerated poetry.lock with bumped deps.

3. README install warning expanded: do NOT install from PyPI (`proxybroker`
   AND `proxybroker2` names are squatted per #186 and pypi/support#10315).
   Always install from this GitHub repo via git+https.

4. Added uv-as-alternative install instructions alongside the existing pip
   instructions. Both go through git+https, never PyPI. uv invokes the
   build backend (poetry-core 2.x) which synthesizes PEP 621 metadata so
   `uv pip install git+...` and `uv add ... @ git+...` both work.

5. README contributor section: Poetry remains canonical; uv supported as a
   best-effort alternative for local dev (uv.lock NOT committed — avoids
   drift with the authoritative poetry.lock).

6. CLAUDE.md restored to poetry-primary state.

Verified:
- `uvx poetry install` succeeds with bumped deps
- 293/293 tests pass via `poetry run pytest`
- `poetry build` produces wheel + sdist
- `docker build` succeeds, container runs
- `uv pip install <source_checkout>` works (poetry-core builds the wheel,
  uv installs it, `proxybroker --version` returns 2.0.0b3)

Codex review caught: README's contributor workflow runs
\`poetry run ruff check / format\`, but ruff wasn't in
[tool.poetry.dev-dependencies] — so a clean \`poetry install\`
left contributors with "command not found: ruff" when they tried to
lint/format per the docs.

The CI workflow papered over this by running \`poetry run pip install
ruff\` ad-hoc before invoking it. That kept CI green but broke the
documented contributor flow.

Fix:
- Add \`ruff = "^0.15.12"\` to [tool.poetry.dev-dependencies]. Now
  \`poetry install\` provides ruff, matching README.
- Drop the redundant \`poetry run pip install ruff\` from the CI
  workflow since ruff is now declared properly.
- Regenerate poetry.lock (ruff 0.15.13 picked up; matches the same
  version range as the pre-commit hook in .pre-commit-config.yaml).

Verified: \`poetry run ruff --version\` → 0.15.13. \`poetry run ruff
check . / format --check .\` both clean. 293/293 tests pass.

Poetry remains the canonical dev tool — `poetry.lock` is the lockfile CI tests against. uv is supported as an alternative for contributors who prefer it:

P2 Badge Remove unsupported uv sync setup step

The new contributor path documents uv sync as a working alternative, but this repository’s pyproject.toml only defines [tool.poetry] and no [project], so uv sync fails immediately (error: No 'project' table found). That means contributors who follow this section cannot complete setup with uv as written; please replace this with a uv command that works with the current Poetry-only metadata (or explicitly mark it unsupported for this repo layout).

Useful? React with 👍 / 👎.

README had v2.0.0b1 hardcoded in 9 places (install commands, section
headers, callouts) from when that was the latest release. Current
release is v2.0.0b3 per pyproject.toml. When I added uv install
instructions in the parent PR, I blindly mirrored the existing
v2.0.0b1 pattern instead of fixing the staleness — same "consider
3 steps further" miss the maintainer called out earlier.

Fix: replace all v2.0.0b1 → v2.0.0b3.

(Follow-up to keep in mind: every release needs a README sweep to
update these strings. Future improvement: extract to a single
"latest release" reference at top, or use shields.io dynamic badge
that pulls from the latest GitHub release.)

P2 Badge Remove broken uv sync setup instruction

This setup command is not runnable with the repository state in this commit: pyproject.toml only defines [tool.poetry] metadata (no [project] table), and running uv sync --dry-run in this tree fails with error: No project table found. As written, contributors following the documented uv path will fail during environment setup before they can run tests or lint.

Per maintainer review, README should be long-lived with minimal per-release
maintenance. Stale-prone content moves to canonical sources or gets dropped.

Removed (rots on every release/commit):
- "v2.0.0b3" version strings in tagline, section headers, install commands,
  marketing callouts (9 occurrences total)
- "131 tests passing" / "100% test coverage" claims (actual: 293 tests,
  60% coverage minimum). Replaced with qualitative "comprehensive test
  coverage" — verifiable claim that doesn't rot.
- Dep version pins in Requirements section (aiohttp 3.12.0+, aiodns 3.4.0+,
  etc.) — duplicated info from pyproject.toml that goes stale on every bump
- Dev-tool version pins (pytest 8.3.5+, pytest-cov 6.1.1+, ruff X.Y) —
  same reason; pyproject.toml is authoritative
- Embedded `--help` CLI output (~40 lines) — went stale per CLI flag change.
  Replaced with `python -m proxybroker --help` pointer.
- "What's New in v2.0.0b3" section — version-by-version changelog belongs
  in CHANGELOG.md, not README

Restructured (one marketing section, one migration guide):
- New "What's New in ProxyBroker2" merges three previously-overlapping
  sections (the old "What's New in v2.0.0b3", "Why ProxyBroker2?", and
  "What's Improved vs v0.3.2" from Migration). Now describes what
  ProxyBroker2 gives over abandoned v0.3.2 — including IPv6 and custom
  providers that the b3 release actually added.
- "Migration from ProxyBroker v0.3.2" becomes a pure how-to-migrate guide
  (Python version, install command, CLI usage diff, API compat) with a
  cross-link to the marketing section above.

Updated to current security/UX direction:
- Install commands drop @v2.0.0b3 tag — `git+https://...` always pulls
  latest from default branch. Note added pointing to GitHub Releases page
  for users who want to pin: "append @<tag> from Releases".
- "Requirements" section slimmed to "Python 3.10-3.14" — the only thing
  users handle manually; all deps auto-installed.
- "Development Tools" → "What contributors handle manually". Only Poetry +
  optional pre-commit. Dropped ReadTheDocs (project infra, not contributor
  tool) and dropped pinned versions of auto-installed dev tools.
- Migrated TODO list to GitHub issue links (was 7 vague bullets).
- Merged duplicate License sections at lines 636 + 683.
- Removed redundant "TWITTER" badge link area at line 4 in the tagline
  (kept the badges below).

Per-release maintenance now: zero. CHANGELOG.md is the only place that
needs touching per version.
