All Fedora Release Engineering Documentation has moved here with source hosted along side the code in the releng pagure repository
Description
Every release prior to the Feature Freeze/Branching Release Engineering retires orphaned packages. This keeps out unowned software and prevents future problems down the road.
Action
The orphan process takes place in stages:
- Detecting a list of orphans and the dependencies that will be broken if the orphans are removed.
- Sending the list of potential orphans to devel@lists.fedoraproject.org for community review and removal from the orphan list.
- Retriring packages nobody wants to adopt.
Detecting Orphans
A script called find_unblocked_orphans.py assists in the detection process. It should be run on a machine that has koji and python-fedora installed. It runs without options and takes a while to complete.
find_unblocked_orphans.py is available in the Engineering git repository.
Announcing Packages to be retired
find_unblocked_orphans.pyoutputs text to stdout on the command line in a form suitable for the body of an email message.
$ ./find-unblocked-orphans.py > email-message
Email the output to the development list (devel@lists.fedodraproject.org) at least a month before the feature freeze, send mails with updated lists as necessary. This gives maintainers an opportunity to pick up orphans that are important to them or are required by other packages.
Retiring Orphans
Once maintainers have been given an opportunity to pick up orphaned packages, the remaining packages are retired.
Bugs
This procedure probably leaves open bugs for the d packages behind. It is not within the scope of releng to take care of these. If bugs are closed, only bugs targeted at Rawhide should be affected, since other branches might still be maintained.
Verification
To verify that the packages were blocked correctly we can use the latest-pkg koji action.
$ koji latest-pkg dist-f21 wdm
This should return nothing, as the wdm package is blocked.
Consider Before Running
Generally we retire anything that doesn't leave broken dependencies. If there are orphans whose removal would result in broken dependencies a second warning should be sent to devel@lists.fedoraproject.org and to <package>-owner@fedoraproject.org for each dependent package.
Allow another couple of days for maintainers to take notice and fix these package so the package repository can be maintained without broken dependencies or needing to the package. It is not good to have broken package dependencies in our package repositories so every effort should be made to find owners or to fix the broken dependencies.
