Current status

• Targeted release: Fedora 30
• Last updated: 2018-12-07
• Tracker bug: <will be assigned by the Wrangler>

Detailed Description

Please see detailed description from original change for information how it works and implemented.

In this change we will switch opt-in into opt-out.

Benefit to Fedora

All the benefits as stated in original change will be turned on for all packages (unless they opt-out).

Scope

• Proposal owners: Flip the switch (in python-rpm-generators) and adjust python-rpm-macros to make feature be opt-out. Send patches to packages to remove unnecessary manual-specified dependencies.

• Other developers: Packagers are strongly advised to remove manually-specified python dependencies if they are set in egg/wheel metadata.

• Release engineering: #7965 (change should be implemented before mass rebuild)
  • List of deliverables: N/A (not a System Wide Change)

• Policies and guidelines: Python Guidelines needs to be updated with instructions how to disable the feature.

• Trademark approval: N/A (not needed for this Change)

Upgrade/compatibility impact

Some new dependencies might be automatically added, but this is rather good because it fixes real bugs.

How To Test

TBD

Users will see less number of packages with missing dependency information.
