The PR is now ready for review.

I'm not sure about the SSLSocket._create() change.

I updated the code to replace BlockingIOError with EAGAIN to make the code more regular/less surprising.

There was a problem hiding this comment.

Thanks. I wish we had a more cleaner way to know what to ignore in general. Can you add the references (as a comment on the PR) where you found about it? or is an empiric finding? No need to add it inside the sources but just so that we know where to look at in the future...

Alternatively, you can maybe add a regression test to exercise the error code?

Without this change, _create() fails with a BlockingIOError exception on Cygwin. I checked the errno and I found that it's EAGAIN.

Alternatively, you can maybe add a regression test to exercise the error code?

I don't see an existing test for getpeername() failure code path in SSLSocket._create(). Writing such test sounds tricky and may rely on internal implementation details. I prefer to skip the test for now.

⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️

Hi! The buildbot iOS ARM64 Simulator 3.x (tier-3) has failed when building commit 0065d22.

What do you need to do:

  1. Don't panic.
  2. Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
  3. Go to the page of the buildbot that failed (https://buildbot.python.org/#/builders/1380/builds/6742) and take a look at the build logs.
  4. Check if the failure is related to this commit (0065d22) or if it is a false positive.
  5. If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

Note: switching to '0065d223ace3fe33ae621779bbb05fc8e0a88a01'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

Hi! The buildbot iOS ARM64 Simulator 3.x (tier-3) has failed when building commit 0065d22.

test_asyncio.test_sock_lowlevel: test_sock_client_racing() failed. It's unrelated to this change.

tests: skip test_requests on Cygwin
5a80d1b 
On our Cygwin CI pipeline, python 3.9 was updated from 3.9.16-1 to 3.9.25-1
some time between August 23rd and August 30th 2026. The new release
includes python/cpython@264b1da, which
breaks `ssl.SSLContext.wrap_socket()` on Cygwin, due to not handling
Cygwin-specific `errno` for unconnected sockets. Same issue is also
present in Cygwin-packaged python 3.12.12-1.

Upstream CPython has merged a fix [1] in `main`, but until that finds
its way into a Cygwin-packaged python (either via new upstream release
or back-port of the fix into Cygwin packages), we should skip the
now-broken `test_requests` on Cygwin.

[1] python/cpython#150419
