[all][tc][ptls] Eventlet: Python 3.13 - Attach your seatbelt
Hi all, As Python 3.13 is close to become a reality, new concerning incompatibilities between this new CPython version and Eventlet also become a reality: - https://github.com/eventlet/eventlet/issues/964 Fedora Python maintainers proposed a patch, but for now the problem remains unsolved. Also, many people reported bugs related to incompatibility between python3.12/dnspython/eventlet/pip-system-cert. There is an example who summarize well the problem https://github.com/eventlet/eventlet/issues/957 Do you have some visibility concerning the adoption of Python 3.13 into Openstack? Turbulences ahead... -- Hervé Beraud Senior Software Engineer at Red Hat irc: hberaud https://github.com/4383/
Yeah: as soon as released, in Debian unstable, and the in Trixie with Dalmatian...

Any update about eventlet and 3.13? FYI, next version of fedora is coming with 3.13 and evenlet may get out of it. On Fri, Jun 7, 2024 at 5:53 PM <thomas@goirand.fr> wrote:

Well, unfortunately, at the moment the support of Python 3.13 is still broken in eventlet and also in greenlet: - https://github.com/python-greenlet/greenlet/pull/396 - https://github.com/eventlet/eventlet/pull/965 Greenlet maintainers are really quiet and did not responded to our multiple solicitations: - https://github.com/python-greenlet/greenlet/pull/410 Le mar. 13 août 2024 à 09:44, Alfredo Moralejo Alonso <amoralej@redhat.com> a écrit :

I have just tried running unit tests for the various Glance-related projects with Python 3.13, using a container[1] that allows me to use manually built wheels for some dependencies. I used the following patches: - for evenlet, PR#965[2] and PR#966[3] - for greenlet, PR#396[4] I got the following results: - glance_store runs all unit tests just fine; - glance can install the dependencies and start running the unit tests, but they hang. As the name of the failing test is not printed on stdout/stderr, I have no clue what is going wrong; - python-glanceclient does not depend on eventlet/greenlet, and all tests pass after applying a patch currently under review[5]. We also need to keep urllib3 <2.0.0 (but this is also an issue on Python3.12). Some interesting lessons learnt here: - the glanceclient patch[5] fixes issues caused by changes in implementation details for mock_open (on which we should have never relied). This might happen in other projects; - the cgi module has been removed in 3.13, and webob depends on it, so we will need to help webob move away from cgi, or install the legacy-cgi package (which is what I had to do for glance & glance_store). I could run some tests on other projects this week, feel free to ping me.

FYI gevent PRs are now merged, so we are now able to continue the work about Python 3.13 on the eventlet side Le lun. 26 août 2024 à 20:56, Cyril Roelandt <cyril@redhat.com> a écrit :
