Fix `proxybroker find` hang on Python 3.10+ and ReadTheDocs build failure by Copilot · Pull Request #196 · bluet/proxybroker2

Copilot · 2026-04-20T07:46:22Z

proxybroker find emits DeprecationWarning: There is no current event loop and hangs on a fresh install (Python 3.10/3.11), and fails outright on 3.12+ where get_event_loop() no longer implicitly creates a loop.

Additionally, the ReadTheDocs build was failing with KeyError: 'copyright' while evaluating docs/source/conf.py.

Changes

proxybroker/cli.py: replace the deprecated asyncio.get_event_loop_policy().get_event_loop() with an explicit new_event_loop() + set_event_loop(), which is the documented pattern for a script entry point on Python 3.10–3.13.

loop = asyncio.new_event_loop()
asyncio.set_event_loop(loop)

docs/source/conf.py: broaden the metadata-extraction regex so it also matches multi-line parenthesized assignments in proxybroker/__init__.py. The previous single-line-only regex failed to capture __copyright__, which is wrapped in parentheses across multiple lines to satisfy ruff format line-length rules, causing the ReadTheDocs Sphinx build to abort with KeyError: 'copyright'. The updated regex uses re.MULTILINE | re.DOTALL and accepts optional parentheses/whitespace, restoring a successful docs build (verified locally with the same sphinx -T -W --keep-going command RTD runs).

[!WARNING]

Replace deprecated `asyncio.get_event_loop_policy().get_event_loop()` with `asyncio.new_event_loop()` + `asyncio.set_event_loop()`. The old call emits DeprecationWarning on Python 3.10/3.11 and fails to create a loop on Python 3.12+ (where `get_event_loop()` no longer implicitly creates one when none is running), causing `proxybroker find` to appear stuck as seen in the reported issue.

@copilot added to allowlist. make sure you completely done proper comprehensive tests and also examined the output accurately.

Done. Comprehensive verification against the exact scenario from the issue (proxybroker find --types HTTP HTTPS -l 10):

aiodns/__init__.py:71 warning (first one in your screenshot): gone — set_event_loop(loop) means asyncio.get_event_loop() inside aiodns finds the loop without warning.
proxybroker/cli.py:447 warning (second one in your screenshot): gone.
Verified with -W default (show all) and -W error::DeprecationWarning (fatal) — both clean.
Also checked grab and serve subcommands — both clean.
CLI test suite: 15/15 pass. Full non-integration suite: 110 pass (the 8 pre-existing errors in test_proxy.py/test_resolver.py are from pytest-asyncio 1.x removing the event_loop fixture — confirmed unrelated by reverting my change and reproducing the same errors).

@copilot test again. and make sure you get the correct outputs from each command

Re-ran every subcommand and captured real output on Python 3.12.3. All commands now produce correct output with no DeprecationWarnings and no hang.

grab --limit 3 --format default (stdout):

<Proxy US 0.00s [] 172.237.73.24:80>
<Proxy US 0.00s [] 157.90.10.15:56030>
<Proxy FI 0.00s [] 5.104.87.17:8050>

find --types HTTP HTTPS --lvl High -l 3 --format default — the exact scenario from the bug report — exit code 0, completed in seconds (previously hung):

<Proxy US 0.04s [HTTP: High] 34.44.49.215:80>
<Proxy US 0.05s [HTTP: High] 154.16.146.45:80>
<Proxy US 0.14s [HTTP: High] 23.88.88.105:80>

serve --host 127.0.0.1 --port 18899 --types HTTP --lvl High: listener bound on 127.0.0.1:18899 within 2 seconds, no warnings in server log.

--help: prints usage correctly.

Test suites: test_cli.py + test_api.py → 32/32 pass. The single remaining aiodns DeprecationWarning surfaced by pytest is from test_broker_creation_without_queue, which instantiates Broker directly without running the CLI path — it pre-dates this PR and is unrelated to the CLI fix (reproduces on main).

@copilot fix docs building failure (in GitHub action)

@copilot fix docs building failure (in GitHub action)

Fixed in 02403c2.

Root cause: the ReadTheDocs build logs showed Sphinx aborting with KeyError: 'copyright' at docs/source/conf.py:94. The regex used to extract metadata from proxybroker/__init__.py only matched single-line __x__ = "value" assignments, but __copyright__ is defined as a multi-line parenthesized string (the form ruff format enforces because the line is >88 chars):

__copyright__ = (
    "Copyright 2015-2018 Constverum, 2018-2025 BlueT - Matthew Lien - 練喆明"
)

Fix: broadened the regex in conf.py to accept optional parentheses and whitespace across lines (re.MULTILINE | re.DOTALL). __init__.py is untouched, so ruff formatting stays happy.

Local verification (same command RTD runs):

$ python -m sphinx -T -W --keep-going -b html -d _build/doctrees -D language=en . $OUT
...
build succeeded.

Exit 0, zero warnings under fail_on_warning: true. Ruff check + format check also pass on both files.

@copilot why there are still some legacy actions/checks required?

@copilot why there are still some legacy actions/checks required?

That's a repository setting, not something I can change from inside this PR. Required status checks are configured under Settings → Branches → Branch protection rules for main (and/or via a repository ruleset). Any check listed there stays "required" on every PR until a maintainer edits that list — even if the corresponding workflow has been removed or renamed, GitHub will keep waiting for a check with that exact name.

If you can share which checks you're seeing as "legacy / required" I can tell you which workflow file (if any) still produces them, but removing them from the required list itself needs repo-admin access in the web UI.

…d_workflow This integration test was flaky across Python versions: it scheduled broker.find() as a task, slept 0.5s, then asserted broker._checker is not None. _checker is set inside find()'s async path, so on slower CI runners (or under heavier startup overhead on a specific Python version) the assertion fired before the task had a chance to run. Both 9e139bd's and 655b774's CI runs hit this on different Python versions; previous master had the same intermittent failure, and PR #196 only partially mitigated it. Replace the sleep-then-assert with a bounded poll: wait up to 5s checking every 100ms for `broker._checker` to become non-None. This removes the race without introducing real latency on healthy runs (typical assertion happens within 100-200ms). Verified locally on Python 3.13 and 3.14: passes deterministically.
