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 email@example.com for community review and removal from the orphan list.
- Removing packages confirmed as orphans from the Fedora package repositories.
A script called
find-unblocked-orphans.py assist in the detection process. It should be run on a machine that has
python-fedora installed. It runs without options, and should take about a minute to complete.
find-unblocked-orphans.py is available in the Release Engineering git repository or downloaded from https://fedorahosted.org/rel-eng/browser/scripts/find-unblocked-orphans.py
Announcing Packages to be d
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 (firstname.lastname@example.org) at least a week before the feature freeze. This gives maintainers an opportunity to pick up orphans that are important to them. Follow-up on the list where necessary.
Once maintainers have been given an opportunity to pick up orphaned packages, the remaining packages are d by blocking them, and creating the
dead.package file in cvs.
Package button in PackageDB to retire a package. This shows interested maintainers, that the package is now retired. There might also be a way to do this with a command line client.
Currently (2013-08-19) we don't have a script to do this, so we re-use
find-unblocked-orphans.py to generate the list. The block-pkg
koji command is used to do the blocking.
$ koji block-pkg --help Usage: koji block-pkg [options] tag package [package2 ...] (Specify the --help global option for a list of other help options) Options: -h, --help show this help message and exit
Koji accepts multiple package names as input and thus we can use the orphan list from the
find-unblocked-orphans.py as input. d packages are only blocked from the latest
dist-f## tag. For example, if we wanted to retire (block)
sbackup, roxterm, and
uisp from rawhide during the development of Fedora 13 we would run the following command:
$ koji block-pkg f21 sbackup roxterm uisp
We just have to remove the existing files from the
master branch and replace them with a
dead.package file whos contents describe why the package is dead.
For example, if we wished to clean up GIT for the roxterm package we would:
$ fedpkg clone roxterm $ cd roxterm $ fedpkg retire --push "Retired on $(date -I) due to lack of a maintainer in preparation to branch Fedora 21"
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.
To verify that the packages were blocked correctly we can use the latest-pkg
$ koji latest-pkg dist-f13 wdm
This should return nothing, as the
wdm package is blocked.
Consider Before Running
Generally we block 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 email@example.com and to <package>-firstname.lastname@example.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.
