Apache ORC Bylaws

Introduction

This document defines the bylaws under which the Apache ORC project operates. It defines the roles and responsibilities of the project, who may vote, how voting works, how conflicts are resolved, etc.

ORC is a project of the Apache Software Foundation (ASF) and the foundation holds the trademark on the name “ORC” and copyright on the combined code base. The Apache Foundation FAQ and How-It-Works explain the operation and background of the foundation.

Apache has a code of conduct that it expects its members to follow. In particular:

  • Be open and welcoming. It is important that we grow and encourage the community of users and developers for our project.

  • Be collaborative. Working together on the open mailing lists and bug database to make decisions helps the project grow.

  • Be respectful of others. Everyone is volunteering their time and efforts to work on this project. Please be respectful of everyone and their views.

ORC is typical of Apache projects in that it operates under a set of principles, known collectively as the “Apache Way”. If you are new to Apache development, please refer to the Incubator project for more information on how Apache projects operate.

Roles and Responsibilities

Apache projects define a set of roles with associated rights and responsibilities. These roles govern what tasks an individual may perform within the project. The roles are defined in the following sections.

Users

The most important participants in the project are people who use our software. The majority of our developers start out as users and guide their development efforts from the user’s perspective. Users contribute to the Apache projects by providing feedback to developers in the form of bug reports and feature suggestions. As well, users participate in the Apache community by helping other users on mailing lists and user support forums.

Contributors

Contributors include all of the volunteers who donate time, code, documentation, or resources to the ORC Project. A contributor that makes sustained, welcome contributions to the project may be invited to become a committer, though the exact timing of such invitations depends on many factors.

Committers

The project’s committers are responsible for the project’s technical management. Committers have the right to commit to the project’s git repository. Committers may cast binding votes on any technical discussion.

Committer access is by invitation only and must be approved by consensus approval of the active Project Management Committee (PMC) members.

If a committer wishes to leave the project or does not contribute to the project in any form for six months, the PMC may make them emeritus. Emeritus committers lose their ability to commit code or cast binding votes. An emeritus committer may request reinstatement of commit access from the PMC. Such reinstatement is subject to consensus approval of active PMC members.

All Apache committers are required to have a signed Individual Contributor License Agreement (ICLA) on file with the Apache Software Foundation. There is a Committer FAQ which provides more details on the requirements for Committers.

A committer who makes a sustained contribution to the project may be invited to become a member of the PMC. The form of contribution is not limited to code. It can also include code review, helping out users on the mailing lists, documentation, testing, etc.

Release Manager

A Release Manager (RM) is a committer who volunteers to produce a Release Candidate. The RM shall publish a Release Plan on the dev mailing list stating the branch from which they intend to make a Release Candidate.

Project Management Committee

The Project Management Committee (PMC) for Apache ORC was created by the Apache Board in April 2015 when ORC moved out of Hive and became a top level project at Apache. The PMC is responsible to the board and the ASF for the management and oversight of the Apache ORC codebase. The responsibilities of the PMC include

  • Deciding what is distributed as products of the Apache ORC project. In particular all releases must be approved by the PMC.

  • Maintaining the project’s shared resources, including the codebase repository, mailing lists, and websites.

  • Speaking on behalf of the project.

  • Resolving license disputes regarding products of the project

  • Nominating new PMC members and committers

  • Maintaining these bylaws and other guidelines of the project

Membership of the PMC is by invitation only and must be approved by a consensus approval of active PMC members.

A PMC member is considered emeritus by their own declaration or by not contributing in any form to the project for over six months. An emeritus member may request reinstatement to the PMC. Such reinstatement is subject to consensus approval of the active PMC members.

The chair of the PMC is appointed by the ASF board. The chair is an office holder of the Apache Software Foundation (Vice President, Apache ORC) and has primary responsibility to the board for the management of the project within the scope of the ORC PMC. The chair reports to the board quarterly on developments within the ORC project.

When the project desires a new PMC chair, the PMC votes to recommend a new chair using Single Transferable Vote voting. The decision must be ratified by the Apache board.

Decision Making

Within the ORC project, different types of decisions require different forms of approval. For example, the previous section describes several decisions which require “consensus approval.” This section defines how voting is performed, the types of approvals, and which types of decision require which type of approval.

Voting

Decisions regarding the project are made by votes on the primary project development mailing list (dev@orc.apache.org). Where necessary, PMC voting may take place on the private ORC PMC mailing list. Votes are clearly indicated by subject line starting with [VOTE]. Votes may contain multiple items for approval and these should be clearly separated. Voting is carried out by replying to the vote mail. Voting may take five flavors:

  • +1 – “Yes,” “Agree,” or “the action should be performed.” In general, this vote also indicates a willingness on the behalf of the voter in “making it happen.”

  • +0 – This vote indicates a willingness for the action under consideration to go ahead. The voter, however, will not be able to help.

  • 0 – The voter is neutral on the topic under discussion.

  • -0 – This vote indicates that the voter does not, in general, agree with the proposed action but is not concerned enough to prevent the action going ahead.

  • -1 – This is a negative vote. On issues where consensus is required, this vote counts as a veto. All vetoes must contain an explanation of why the veto is appropriate. Vetoes with no explanation are void. It may also be appropriate for a -1 vote to include an alternative course of action.

All participants in the ORC project are encouraged to show their agreement for or against a particular action by voting, regardless of whether their vote is binding. Nonbinding votes are useful for encouraging discussion and understanding the scope of opinions within the project.

Approvals

These are the types of approvals that can be sought. Different actions require different types of approvals.

  • Consensus Approval – Consensus approval requires 3 binding +1 votes and no binding vetoes.

  • Lazy Consensus – Lazy consensus requires at least one +1 vote and no -1 votes (‘silence gives assent’).

  • Lazy Majority – A lazy majority vote requires 3 binding +1 votes and more binding +1 votes than -1 votes.

  • Lazy 2/3 Majority – Lazy 2/3 majority votes requires at least 3 votes and twice as many +1 votes as -1 votes.

Vetoes

A valid, binding veto cannot be overruled. If a veto is cast, it must be accompanied by a valid reason explaining the reasons for the veto. The validity of a veto, if challenged, can be confirmed by anyone who has a binding vote. This does not necessarily signify agreement with the veto - merely that the veto is valid. If you disagree with a valid veto, you must lobby the person casting the veto to withdraw their veto. If a veto is not withdrawn, any action that has already been taken must be reversed in a timely manner.

Actions

This section describes the various actions which are undertaken within the project, the corresponding approval required for that action and those who have binding votes over the action.

Code Change

A change made to a codebase of the project requires lazy consensus of active committers other than the author of the patch. The code can be committed after the first +1.

Product Release

To make a release, the release manager creates a release candidate and a vote requiring a lazy majority of the active PMC members is required. Once the vote passes, the release candidate becomes an official release.

Adoption of New Codebase

When the codebase for an existing, released product is to be replaced with an alternative codebase, it requires a lazy 2/3 majority of PMC members. This also covers the creation of new sub-projects and submodules within the project.

New Committer

When a new committer is proposed for the project, consensus approval of the active PMC members is required.

New PMC Member

To promote a committer to a PMC member requires consensus approval of active PMC members.

If the vote passes, the Apache Board must be notified to make the change official.

Committer Removal

Removal of commit privileges requires a lazy 2/3 majority of active PMC members.

PMC Member Removal

Removing a PMC member requires a lazy 2/3 majority of active PMC members, excluding the member in question.

If the vote passes, the Apache Board must be notified to make the change official.

Modifying Bylaws

Modifying this document requires a lazy majority of active PMC members.

Voting Timeframes

Votes are open for a minimum period of 72 hours to allow all active voters time to consider the vote. For holiday weekends or conferences, consider using a longer vote window. Votes relating to code changes are not subject to a strict timetable but should be made as timely as possible.
