Bug report

calling http.client.HTTPConnection._tunnel() may result in a ResourceWarning because the response is not closed

this results in an intermittent failure on the urllib3 test test/with_dummyserver/test_proxy_poolmanager.py::TestHTTPProxyManager::test_tunneling_proxy_request_timeout[https-https] with ResourceWarnings enabled, see https://github.com/urllib3/urllib3/actions/runs/4638944124/jobs/8209257011#step:6:2471 and https://github.com/urllib3/urllib3/blob/4d425a2d767ce2e0c988fff4385046ea57458c49/test/with_dummyserver/test_proxy_poolmanager.py#L480-L498

py-urllib3: updated to 2.2.3
fefdfd3 
2.2.3 (2024-09-12)
==================

Features
--------

- Added support for Python 3.13.

Bugfixes
--------

- Fixed the default encoding of chunked request bodies to be UTF-8 instead of ISO-8859-1.
  All other methods of supplying a request body already use UTF-8 starting in urllib3 v2.0.
- Fixed ResourceWarning on CONNECT with Python < 3.11.4 by backporting python/cpython#103472.
- Adjust tolerance for floating-point comparison on Windows to avoid flakiness in CI
- Fixed a crash where certain standard library hash functions were absent in restricted environments.
- Fixed mypy error when adding to ``HTTPConnection.default_socket_options``.

HTTP/2 (experimental)
---------------------

HTTP/2 support is still in early development.

- Excluded Transfer-Encoding: chunked from HTTP/2 request body
- Added version checking for ``h2`` (https://pypi.org/project/h2/) usage.

  Now only accepting supported h2 major version 4.x.x.
- Added a probing mechanism for determining whether a given target origin
  supports HTTP/2 via ALPN.
- Add support for sending a request body with HTTP/2

Deprecations and Removals
-------------------------

- Note for downstream distributors: the ``_version.py`` file has been removed and is now created at build time by hatch-vcs.
- Drop support for end-of-life PyPy3.8 and PyPy3.9.

Update python-urllib3 to version 2.2.3 / rev 68 via SR 1205339
c834ec9 
https://build.opensuse.org/request/show/1205339
by user StevenK + anag+factory
- Update to 2.2.3:
  * Features
    + Added support for Python 3.13.
  * Bugfixes
    + Fixed the default encoding of chunked request bodies to be UTF-8
      instead of ISO-8859-1. All other methods of supplying a request body
      already use UTF-8 starting in urllib3 v2.0.
    + Fixed ResourceWarning on CONNECT with Python < 3.11.4 by backporting
      python/cpython#103472.
    + Fixed a crash where certain standard library hash functions were absent
      in restricted environments.
    + Added the Proxy-Authorization header to the list of headers to strip
      from requests when redirecting to a different host. As before,
      different headers can be set via Retry.remove_headers_on_redirect.
    + Allowed passing negative integers as amt to read methods of
      http.client.HTTPRe
