@popravich can you take a look to this MR?

Also, I would like to ask you for a favor. could you publish a new release with the last two changes?

We are having a lot of issues with the default aiohttp Connector, that uses the default DNS resolver and a forerver cache table. We have implemented our TCPConnector - I expect that this finally will be also merged in the 2.X series of aiohttp, but due to the current architecture of aioes we can not inject our own implementation.

In any case, thanks in advance!

I think here in Transport it should be connector_factory,
otherwise a single connector will be shared between different Connections (ClientSessions)
and when some connection will get dropped underlying ClientSession will close the shared connector
making other connections broken as well.
I think it could look like this:

connector_factory=lambda: None

[pfreixes]

You are right, going to change it and covering it with test.

[popravich]

Please add test also.

[pfreixes]

@popravich done.

[popravich]

[pfreixes]

you welcome, any chance to get a 0.7.1 release? otherwise, any ETA?

[popravich]

Ok, I will do a release in a several hours
