feat: Redirect tracing in rust to python logging

[pavelzw]

Description

Fixes #{issue}

How Has This Been Tested?

pixi run python foo.py and

# foo.py
from rattler.package_streaming import fetch_raw_package_file_from_url
from rattler import Client, setup_logging
import asyncio

import logging

FORMAT = "%(levelname)s %(name)s %(asctime)-15s %(filename)s:%(lineno)d %(message)s"
logging.basicConfig(format=FORMAT)
logging.getLogger().setLevel(logging.INFO)
logging.getLogger("rattler.rattler_package_streaming").setLevel(logging.DEBUG)

setup_logging()


async def main():
    foo = await fetch_raw_package_file_from_url(
        Client(),
        "https://prefix.dev/conda-forge/noarch/polars-1.41.2-pyh58ad624_0.conda",
        "site-packages/polars/__init__.py",
    )
    print(foo[:20])


asyncio.run(main())

alternatively, something like this if you want to use loguru instead of logging

Details

import asyncio
import logging
import sys

from loguru import logger

from rattler import Client, setup_logging
from rattler.package_streaming import fetch_raw_package_file_from_url


class LoguruHandler(logging.Handler):
    def emit(self, record: logging.LogRecord) -> None:
        try:
            level = logger.level(record.levelname).name
        except ValueError:
            level = record.levelno

        logger.opt(depth=6, exception=record.exc_info).log(level, record.getMessage())


logger.remove()
logger.add(sys.stderr, level="DEBUG")

rattler_logger = logging.getLogger("rattler")
rattler_logger.handlers.clear()
rattler_logger.addHandler(LoguruHandler())
rattler_logger.setLevel(logging.DEBUG)
rattler_logger.propagate = False


setup_logging()


async def main():
    foo = await fetch_raw_package_file_from_url(
        Client(),
        "https://prefix.dev/conda-forge/noarch/polars-1.41.2-pyh58ad624_0.conda",
        "site-packages/polars/__init__.py",
    )
    print(foo[:20])


asyncio.run(main())
