🚀 New issue to wemake-services/wemake-python-styleguide by @luminoso
📝 False positive for WPS457 when using asyncio to control loops (#3573)


What's wrong

For the code:

import asyncio


async def infinite_loop() -> None:
    try:
        while True:
            await asyncio.sleep(1)
            print("I'm alive. And doing work.")
    except asyncio.CancelledError:
        print("Loop cancelled")


t = asyncio.create_task(infinite_loop())
await asyncio.sleep(5)
t.cancel()

WPS457: Found an infinite while loop is raised. But infinite loop is being handled. Just not within the while loop.

How it should be

Not to raise WPS457.

Not 100% sure here if it is the best practice or not.
Also probably the solution is too complex and is just easier to add a noqa in the code.

    return decorator

This code falsy raises two WPS430 violations.

  69:9     WPS430 Found nested function: factory
  async def factory(
  ^

  84:9     WPS430 Found nested function: factory
  def factory(
  ^

But, the name is correct. decorator name is in whitelist of names. This is a false positive.
We need to fix it and add a test case.

📝 `WPS617` false positive with keyword args (#3596)

self._media_by_precedence = sorted(
    (
        media_type
        for parser in self._parsers.values()
        if (media_type := MediaType(parser.content_type)).quality != 0
    ),
    key=lambda media: (media.specificity, media.quality),  # noqa: WPS617
    reverse=True,
)

It says:

django_modern_rest/negotiation.py

  52:17    WPS617 Found lambda assigned as an attribute
  key=lambda media: (media.specificity, media.quality),
      ^

Which is clearly a bug, it is a named param, not an attribute.
PRs are welcome, this is easy to fix.

📝 Remove `WPS354` (#3601)


This rules has more problems that it solves:

1. Two yields and yield from are two different things
2. Async iterators cannot use yield from, but WPS354 still raises even in async def

So, it is time to remove this rule. I was wrong about that :(
See other rules with disabled_since attribute on how to disable a rule.

📝 `WPS457` false positive with `while` in `try` / `except` (#3603)


I have the following code:

def factory() -> Iterator[bytes]:
    try:
        while True:  # noqa: WPS457
            yield async_to_sync(async_anext)(iterator)
    except StopAsyncIteration:
        pass

It should not raise WPS457, because while is in try / except.
It can clearly raise and we handle the error. So, it is not infinite.

PRs are welcome! 👍
