Hello ! I saw that error too.

Here is a simple code to reproduce:

import asyncio

from arsenic import get_session, browsers, services

async def launch_browser():
    service = services.Geckodriver()
    browser = browsers.Firefox(
        acceptInsecureCerts=True,
    )

    async with get_session(service, browser) as session:
        await session.get('http://127.0.0.1:8000/index.php', timeout=5)
        page_source = await session.get_page_source()

async def main():
    await asyncio.gather(
        launch_browser(),
    )

asyncio.run(main())

Here the timeout is set to 5 for arsenic. The php script is sleeping for 6 seconds:

<?php
sleep(6);
?>

Traceback:

    raise asyncio.TimeoutError from None
asyncio.exceptions.TimeoutError

Also that timeout is not raised after the delay given to the timeout argument so if the page waits 30 secs the timeout is raised after 30secs, not 5 secs

Behavior seen:

  • the timeout parameter given to session.get was not used
  • an asyncio exception (from asyncio.exceptions was raised)

Expected behavior:

  • a timeout exception is raised as soon as the specified timeout is reached
  • an arsenic exception is raised (ArsenicTimeout)

Versions used:

  • arsenic==21.8
  • Python 3.10.6
  • geckodriver 0.26.0 (e9783a644016 2019-10-10 13:38 +0000)
  • Firefox 104.0 (64 bits)

from arsenic.
