Flag Day 2016

On the 12th of December 2016 at 00:00UTC, there will be end user impacting changes the packager work flow.

Kerberos for Authentication

Koji supports multiple authentication mechanisms. Fedora infrastructure has set up a freeipa instance internally that has credential syncing to fas. We are working on ensuring that gssapi caching is supported so that you can have multiple TGT's and the ability to work in multiple realms at once. you can get started today by doing kinit <fas username>@FEDORAPROJECT.ORG if you move your ~/.fedora.cert file out of the way authentication will still work.

Well known ssl certificates for koji and pkgs

Using well known certs for this is the last step needed to have switch to hsts and default to https:// when connecting to any fedora service. It will also remove a lot of questions that new people have when connecting to koji via https.

Disable SSL authentication in koji and pkgs

With the switch to keberos and the change of ssl certificates on the koji and pkgs servers we will be disabling the ability to login to koji using a ssl certificate completely. This change will require new koji client configurations for everyone

Gate rawhide builds

Gating will enable us to sign rawhide builds and switch the rawhide repo to having gpgcheck enabled.

Sha512 for sources

sources files will switch to use sha512 instead of md5 to identify upstream sources. You will need a new fedpkg that understands this format.

What do I have to do

In order to achieve everything we have to break end user configurations. All users will need to have new enough versions of fedora-packager, fedpkg, rpkg, koji. the exact versions are listed below. We will be aiming to have everything pushed stable right before the flag day. Some of the changes will not be compatible with the existing setup. We anticipate keeping everyone informed as we move forward about any actions that will need to be taken on the developer side.

  • Question: what version(s) of all the packager tools will I need to be using on December 12th?
  • Answer: These versions are needed. They may be still in updates-testing:
    • python-cccolutils-1.4-1
    • fedpkg-1.26-2
    • fedora-packager-
    • pyrpkg-1.47-3
    • koji-1.11.0-1
  • Question: How does the rawhide gating work? Aren't you slowing things down?
  • Answer: It works by landing all the rawhide builds in a pending tag. Then the autosigner signs them and places them into the normal rawhide tag. This is only delaying builds by how long it takes to sign them. We may add QA checks on this pending step later, but none are being added now.
  • Question: What is this '' ?
  • Answer: This is the new place to download and view package specs / patches. Package maintainers will still need to use ssh to connect to to commit changes, but https access will be via
