aiohttp.errors is gone

[jwilk]

Long story short

The aiohttp.errors module used to be public, documented API.
Now it's gone.

If this backwards-incompatible change is intentional, then it should be documented.

Steps to reproduce

$ python3 -c 'import aiohttp.errors'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named 'aiohttp.errors'

$ grep -Fcw aiohttp.errors CHANGES.rst HISTORY.rst

Your environment

aiohttp 2.0.3

yeah it sucks not being able to handle aiohttp exceptions if you wanted to. Unless I pull an hack and do this from aiohttp import errors.

aiohttp.errors was never ment to be used directly

[AraHaan]

Except when you want to handle aiohttp exceptions in another library (discord.py is one of those libraries) to know when you get an 200, 404, or w/e error code it returns or when the request was bad / invalid. They also use ServerDisconnectedError to know when to reconnect. (the service the library covers has an HEARTBEAT_ACK)

@jwilk updated are updated

[bartaelterman]

@fafhrd91 if your code raises those errors, why shouldn't we import them directly so we can catch them?

[fafhrd91]

Something like this should be enough:

try:
    yield from aiohttp.request()
except aiohttp.ClientError as err:
    print(err)
