I will add tests and documentation changes soon! Wanted to open this early to get @asvetlov's opinion (and others' too maybe?) on wether this is a breaking change or not. THANK YOU SO MUCH for all the work on aiohttplib! It is heavily used in the open science / climate science ecosystem, and we are grateful for it. |

@Dreamsorcerer I really appreciate all the code clarity suggestions, thank you. I've implemented all of them, and tried to keep clarifying comments as well. I've also added three unit tests. I'm not sure if |

I also appreciate the checklist in the PR body template, and believe I have ticked all the boxes. |
|
I do not know what the correct version this is to be added in. I'd love to see this released sooner than later (:D) - would that be 3.8.4 or 3.9 or 4.x? It probably is either 3.9 or 4.x, but I am not sure what the next release is to be... |
|
3.9 if backoported. |
|
I see two relevant errors perhaps in Both of these are things we guard against with an However, these intermediate bools were added at your explicit request, @webknjaz (see #7131 (comment)). I personally find what mypy want, without intermediate boolean variables, a lot more readable as well. However, at this juncture I'll basically do whatever it is that you want to get this PR merged - so if you can point me to a way to make mypy happy while also keeping your intermediate variables I'll do so :) |
Yeah, I don't think the second one improves readability at all. The first one is also scheduled for removal in a few years anyway, so I personally am not bothered about keeping them. |
Don't use intermediary bools for None checks
|
@Dreamsorcerer i've hence merged in yuvipanda#3 so mypy should pass now! |
|
yay, all tests seem to pass now! |
|
Just wanted to check-in on this again, @Dreamsorcerer and @webknjaz :) |

The windows test failures seem unrelated? And the missing code coverage result is due to differences in python versions, so I hope that's ok. |
|
This time there's a macos test failure :) So i'd imagine those are flakes. the codecov warning is one missed line, and that's due to differing behavior in versions of python. I hope that's ok to ignore. |
Not flaky, they just don't work yet. If check has passed, then that means the tests are passing correctly.
Hmm, that's not right. We run on Python 3.7-3.11, so if there was test coverage, it would have run. However, that code doesn't seem important and will be removed in a future version, so I'm not going to bother investigating. |
|
If @webknjaz is happy to resolve his comments, then I'll merge it in. |
Ah, hmm. I'm not sure why that's happening then :|
I agree wholeheartedly! |
|
I'm going on vacation from tuesday for 15 days, and wanted to check-in and see if there is anything I can do before I go :) |
|
Just another gentle ping, as I slowly pick up back from vacation @Dreamsorcerer @webknjaz :) |
I suppose you're talking about this |

Currently, setting `trust_env=True` in `ClientSession` will only use the `.netrc` file if present for authentication to proxies. With this change, the credentials will also be used for regular HTTP hosts, and Basic Auth will be sent if an appropriate entry is present in the user's `.netrc` file. PR #7131.

What do these changes do?
Currently, setting
trust_env=TrueinClientSessionwill only use the.netrcfile if present for authentication to proxies. With this change, the credentials will
also be used for regular HTTP hosts, and Basic Auth will be sent if an appropriate
entry is present in the user's
.netrcfile.Are there changes in behavior for the user?
YES! Currently, their .netrc file will be ignored when not making proxy requests. This
will start sending any credentials in netrc files to hosts.
The behavior of this PR seems to have possibly been the suggested behavior when
netrc support was initially added, based on this comment: #2584 (comment).
The behavior with this PR applied also matches requests and other libraries. In fact, this
was a deep dive output after trying to figure out why accessing NASA open data with requests
works but aiohttp does not :D (nsidc/earthaccess#188 has the trail crumbs).
If this is considered a breaking change, I'm happy to instead introduce a new param that
toggles this behavior instead. However,
trust_envis what requests and other libraries use,so may be ok.
