Import error in aiohttp with yarl v1.0.0

[panagiks]

Hello,

with yarl v1.0.0 I get the following error when doing from aiohttp import web:

  File "/usr/local/lib/python3.5/dist-packages/aiohttp/web.py", line 15, in <module>
    from . import (hdrs, web_exceptions, web_fileresponse, web_middlewares,
  File "/usr/local/lib/python3.5/dist-packages/aiohttp/web_middlewares.py", line 5, in <module>
    from aiohttp.web_urldispatcher import SystemRoute
  File "/usr/local/lib/python3.5/dist-packages/aiohttp/web_urldispatcher.py", line 21, in <module>
    from yarl import URL, unquote
ImportError: cannot import name 'unquote'

using aiohttp-2.3.7.

Ah sorry ... I just saw in the changelog that the drop was intentional. I'll leave the issue open just for reference. Feel free to close it if you prefer :)

Just encountered this same problem, but it's not clear why these were dropped. Change log references #155 but doesn't explain why they were dropped.

This private/public "collision" is a history of a year long...

Unfortunately this has broken all my builds :( .. currently I'm trying to pin multidict and yarl to previous versions, but with no success .. not sure if I'm now hitting an issue with pipenv..

I have multidict pinned to 3.0.0 and yarl to 0.11.0 ... any ideas on how to get around this would be very welcome ... !

Ok, scratch that, managed to fix it by pinning aiohttp to 2.3.8 and unpinning yarl and multidict ...

aiohttp is fixed
