[edit] Introduction

The purpose of this document is to present a policy/workflow that will be used when handling package updates. It specifies when, where and which kind of package updates may occur.

[edit] Scope

  • This policy concerns only currently supported Fedora releases.
    • Rules for the current pending release will be added to this document. Rules for Rawhide may come in the future.
  • Security updates that fall into the Important package set are subject to this policy. Security updates that do not fall into this category are not subject to this policy.

[edit] Workflows

Two workflows are defined, for different sets of packages. The sets are important packages and other packages.

[edit] Important package set

The important package set consists of:

  • The current critical path package set
  • All major desktop environments' core functionality (GNOME, KDE, XFCE, LXDE)
  • Package updating frameworks (gnome-packagekit, kpackagekit)
  • Major desktop productivity apps. An initial list would be firefox, kdebase (konqueror), thunderbird, evolution, kdepim (kmail).

[edit] Other package set

The other package set consists of all packages not in the important package set.

[edit] Important workflow

All package updates are submitted to the 'updates-testing' repository. Then they await initial sanity test acceptance, a process owned by the Quality Assurance team. Acceptance is granted according to Initial requirements. The decision is based on the result of Package update acceptance test plan, which is executed automatically by AutoQA. When the approval is granted, the update is pushed to the 'updates-testing' repository.

Next, the updates must meet all of these requirements:

  • Updates must reach a specified positive Bodhi karma threshold [1] provided by a defined team (e.g. proventesters). These qualified testers should consider feedback (especially negative feedback) from other testers in deciding whether to provide approval, as well as their own tests.
  • Updates must spend some minimum amount of time [1] in updates-testing. This requirement does not hold for security updates.

After submitting to 'updates' repository another round of automated AutoQA acceptance tests is run. Acceptance is granted according to Stable requirements. As a final point Release Engineering ensures that Stable requirements were satisfied and they sign off and push the update to 'updates'.

[edit] Other workflow

All package updates are submitted to the 'updates-testing' repository. Then they await initial sanity test acceptance, a process owned by the Quality Assurance team. Acceptance is granted according to Initial requirements. The decision is based on the result of Package update acceptance test plan, which is executed automatically by AutoQA. When the approval is granted, the update is pushed to the 'updates-testing' repository.

Next, the updates must meet at least one of these requirements:

  • Updates must reach a specified positive Bodhi karma threshold [1]. Anyone may provide karma to an update.
  • Updates must spend some minimum amount of time [1] in updates-testing.

Proposed time would be one week, but is open to negotiation. We can track downloads with our one Fedora-infrastructure controlled mirror as mechanism to see what usage the package is getting.

When at least one of the constraints is satisfied the package maintainer may submit the update to the 'updates' repository.

After submitting to 'updates' repository another round of automated AutoQA acceptance tests is run. Acceptance is granted according to Stable requirements. As a final point Release Engineering ensures that Stable requirements were satisfied and they sign off and push the update to 'updates'.

[edit] Initial Requirements

  • AutoQA: Test Package Sanity - Packages must be able to be installed, removed, upgraded, etc.
  • AutoQA: Packages must not break dependencies in updates + updates-testing.
  • AutoQA: Packages must not introduce file/package conflicts in updates + updates-testing.
  • + maybe some more

[edit] Stable Requirements

  • AutoQA: Initial requirements are re-checked and met.
  • AutoQA: Packages must not break upgrade path.
  • RelEng: The package update type falls into the list of allowed update types (document not approved yet, just a sample).
  • + maybe some more


[edit] Exception Process

Package maintainers may ask for exception, when:

  • they don't agree with QA rejecting their update
  • they need to push an update without fully adhering to policy requirements
    • this is suitable for high-important bug-fix updates, which repair severe regressions/breakages
    • some other candidates?
  • they don't agree with RelEng rejecting their update

The process of asking for an exception is yet to be defined. It can be a majority vote from FESCo.

[edit] Responsibilities

  • When a serious problem is found in a not yet released updated package, package update builder is responsible for removing this update from 'updates-testing' repository. Fedora Update System must provide this option for package update builder, package maintainer, Quality Assurance team and Release Engineering team.
  • The Fedora Update System is responsible for sending notifications to package update builder and package maintainer when:
    • the update receives a result from Package update acceptance test plan
    • the update has fulfilled requirements for submitting into 'updates' repository
    • the update has been accepted or rejected to be pushed to 'updates' repository by Release Engineering team
    • the update becomes available in the 'updates' repository
  • Even though some security updates do not fall within this policy, the Quality Assurance team is still obliged to test the packages, after they're pushed if necessary, and report any regressions that need to be fixed to the maintainer.
