Default timeout stopped working starting from urllib3 2.0.0

[Vsevolod Fedorov]

urllib3 library does not use socket._GLOBAL_DEFAULT_TIMEOUT as it's default value starting from version 2.0.0. Now it uses it's own value. So, when timeout passed to it is compared to default one, it fails with the following trace:

 File "/usr/local/lib/python3.8/site-packages/jenkins/__init__.py", line 822, in get_info
    return json.loads(self.jenkins_open(
  File "/usr/local/lib/python3.8/site-packages/jenkins/__init__.py", line 560, in jenkins_open
    return self.jenkins_request(req, add_crumb, resolve_auth).text
  File "/usr/local/lib/python3.8/site-packages/jenkins/__init__.py", line 576, in jenkins_request
    self.maybe_add_crumb(req)
  File "/usr/local/lib/python3.8/site-packages/jenkins/__init__.py", line 373, in maybe_add_crumb

    r = adapter.send(request, **kwargs)
  File "/usr/local/lib/python3.8/site-packages/requests/adapters.py", line 483, in send
    timeout = TimeoutSauce(connect=timeout, read=timeout)
  File "/usr/local/lib/python3.8/site-packages/urllib3/util/timeout.py", line 119, in __init__
    self._connect = self._validate_timeout(connect, "connect")
  File "/usr/local/lib/python3.8/site-packages/urllib3/util/timeout.py", line 156, in _validate_timeout
    raise ValueError(

This is one possible solution.

I think we are hitting the same issue with our jobs:

21:45:19 ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
21:45:19 botocore 1.29.129 requires urllib3<1.27,>=1.25.4, but you have urllib3 2.0.2 which is incompatible.

As a temporary workaround, you can fix urllib3 version in your requirements.txt file, like:
urllib3<2.0.0

[OpenStack Infra (hudson-openstack)]

Fix proposed to branch: master
Review: https://review.opendev.org/c/jjb/python-jenkins/+/882757

[Ken Dreyer (Red Hat) (kdreyer-redhat)]

Vsevolod I've submitted your patch with modifications at https://review.opendev.org/c/jjb/python-jenkins/+/882757

[Martin Wallgren (ub71-martin-b69y)]

Another workaround if you don't want to pin urllib3 is to set your own timeout in the Jenkins constructor

            jenkins.Jenkins(
                jenkins_url,
                username,
                password,
                timeout=60,
            )

[Bogdan Sucheana (bsucheana)]

Another solution is to add in your config file (e.g. jenkins_jobs.ini) the timeout property, down in the [jenkins] section, like so:

[...]

[jenkins]
user=youruser
password=yourpassword
url=http://localhost:8080/
timeout=60
query_plugins_info=False
##### This is deprecated, use job_builder section instead
#ignore_cache=True

[...]

I'm using Python 3.11.4, so hopefully this will get fixed once the above patch is being merged.
