Update Sphinx to version 2 and drop Python 2 support from Sphinx
The version 2.0.x of Sphinx, popular Python documentation generator and framework, is expected to be released in early 2019. It drops support for Python 2. As part of Finalizing Fedora's Switch to Python 3, we update
to 2.0.x and we drop
and related packages from Fedora 31 and further.
Package maintainers using Sphinx on Python 2 have three options:
- they stop using Python 2 entirely (preferred), dropping their python2 subpackages if not dependent upon by other packages,
- they switch to Sphinx on Python 3 for building their documentation,
- they stop building documentation.

We will remove the following (sub)packages:

(already removed in F30)
The following (source) packages currently (2019-02-06) BuildRequire any of the above and will need to be modified to stop BuildRequiring them:
As said in the summary, packages will either switch to Python 3 Sphinx or stop building the docs. Change owners can provide guidance and help, yet they cannot be expected to fix all the packages.
The following tools will be switched to Python 3:
Benefit to Fedora
Fedora is the leading environment for Python development and will include the newest and greatest Sphinx for users and packagers. The removal of Python 2 Sphinx will help in getting rid of a significant amount of Python 2 usage, as Fedora's long term plan is to get rid of this legacy interpreter. Python 2 is deprecated in Fedora and its upstream support ends on 2020-01-01, very early in the Fedora 31 life time.
- Proposal owners: remove above-mentioned packages as soon as possible, update
to 2.0.0 or newer, provide guidance and help.
- Release engineering: #8100 (no Release Engineering impact is anticipated)
- List of deliverables: empty
- Policies and guidelines: none
- Trademark approval: not needed for this Change
Fedora users using RPM-packaged Sphinx will use Sphinx on Python 3 by default, as many would expect. Fedora users still needing to use Sphinx running on Python 2 will use Python virtual environment and pip.
How To Test
Already covered by sections above.
Described by the sections above.
- Contingency mechanism: If absolutely needed, the change owners will add compatibility
package with Sphinx 1.8.x but they are not willing to maintain it, so they plan to orphan it soon after Fedora 31 is released.
- Contingency deadline: any time before release
- Blocks release? No
- Blocks product? No
