Abstract
|
||
========
|
||
|
||
This PEP proposes a new model of Python governance based on a Council
|
||
of Auditors (CoA) tasked with making final decisions for the language.
|
||
It differs from PEP 8010 by specifically not proposing a central
|
||
singular leader, and from PEP 8011 by disallowing core committers from
|
||
being council members. It describes the size and role of the council,
|
||
how the initial group of council members will be chosen, any term
|
||
limits of the council members, and how successors will be elected.
|
||
|
||
It also spends significant time discussing the intended behaviour of
|
||
this model. By design, many processes are not specified here but are
|
||
left to the people involved. In order to select people who will make
|
||
the best decisions, it is important for those involved to understand
|
||
the expectations of the CoA but it is equally important to allow the
|
||
CoA the freedom to adjust process requirements for varying
|
||
circumstances. This only works when process is unspecified, but all
|
||
participants have similar expectations.
|
||
|
||
This PEP does *not* name the members of the CoA. Should this model be
|
||
adopted, it will be codified in PEP 13 along with the names of all
|
||
officeholders described in this PEP.
|
||
|
||
The Importance of the Grey Area
|
||
===============================
|
||
|
||
In any actual decision-making process, there is going to be grey area.
|
||
This includes unexpected scenarios, and cases where there is no
|
||
"correct" answer.
|
||
|
||
Many process plans attempt to minimise grey area by defining processes
|
||
clearly enough that no flexibility is required.
|
||
|
||
This proposal deliberately goes the other way. The aim is to provide a
|
||
robust framework for choosing the best people to handle unexpected
|
||
situations, without defining how those people should handle those
|
||
situations.
|
||
|
||
Examples are provided of "good" responses to some situations as an
|
||
illustration. The hope is that the "best" people are the best because
|
||
they would live up to those examples. The process that is proposed has
|
||
been designed to minimise the damage that may be caused when those
|
||
people turn out not to be the best.
|
||
|
||
Grey area is guaranteed to exist. This proposal deliberately embraces
|
||
and works within that, rather than attempting to prevent it.
|
||
|
||
Model Overview
|
||
==============
|
||
|
||
Key people and their functions
|
||
------------------------------
|
||
|
||
The Council of Auditors (CoA) is a council of varying size, typically
|
||
two to four people, who are elected for the duration of a Python
|
||
release. One member of the CoA is considered the President, who has
|
||
some minor points of authority over the other members.
|
||
|
||
The CoA has responsibility for reviewing controversial decisions in
|
||
the form of PEPs written by members of the core development team. The
|
||
CoA may choose to accept a PEP exactly as presented, or may request
|
||
clarification or changes. These changes may be of any form and for any
|
||
reason. This flexibility is intentional, and allows the process to
|
||
change over time as different members are elected to the CoA. See the
|
||
later sections of this document for examples of the kinds of requests
|
||
that are expected.
|
||
|
||
The CoA only pronounces on PEPs submitted to python-committers. There
|
||
is no expectation that the CoA follows or participates on any other
|
||
mailing lists. (Note that this implies that only core developers may
|
||
submit PEPs. Non-core developers may write and discuss proposals on
|
||
other mailing lists, but without a core developer willing to support
|
||
the proposal by requesting pronouncement, it cannot proceed to
|
||
acceptance. This is essentially the same as the current system, but is
|
||
made explicit here to ensure that members of the CoA are not expected
|
||
to deal with proposals that are not supported by at least one core
|
||
developer.)
|
||
|
||
The CoA may not delegate authority to individuals who have not been
|
||
elected by the core developer team. (One relevant case here is that
|
||
this changes the implementation of the existing BDFL-Delegate system,
|
||
though without necessarily changing the spirit of that system. See the
|
||
later sections, particularly example scenario four, for more
|
||
discussion on this point.)
|
||
|
||
The Release Manager (RM) is also permitted the same ability to request
|
||
changes on any PEPs that specify the release they are responsible for.
|
||
After feature freeze, the RM retains this responsibility for their
|
||
release, while the CoA rotates and begins to focus on the subsequent
|
||
release. This is no different from the current process. The process
|
||
for selection of a RM is not changed in this proposal.
|
||
|
||
Core developers are responsible for electing members of the CoA, and
|
||
have the ability to call a "vote of no confidence" against a member of
|
||
the CoA. The details of these votes are discussed in a later section.
|
||
|
||
Where discussions between core developers and members of the CoA
|
||
appear to be ongoing but unfruitful, the President may step in to
|
||
overrule either party. Where the discussion involves the President, it
|
||
should be handled using a vote of no confidence.
|
||
|
||
Members of the CoA may choose to resign at any point. If at least two
|
||
members of the CoA remain, they may request a new election to refill
|
||
the group. If only one member remains, the election is triggered
|
||
automatically. (The scenario when the President resigns is described
|
||
in a later section.)
|
||
|
||
The intended balance of power is that the core developers will elect
|
||
members of the CoA who reflect the direction and have the trust of the
|
||
development team, and also have the ability to remove members who do
|
||
not honour commitments made prior to election.
|
||
|
||
Regular decision process
|
||
------------------------
|
||
|
||
Regular decisions continue to be made as at present.
|
||
|
||
For the sake of clarity, controversial decisions require a PEP, and
|
||
any decisions requiring a PEP are considered as controversial.
|
||
|
||
The CoA may be asked to advise on whether a decision would be better
|
||
made using the controversial decision process, or individual members
|
||
of the CoA may volunteer such a suggestion, but the core development
|
||
team is not bound by this advice.
|
||
|
||
Controversial decision process
|
||
------------------------------
|
||
|
||
Controversial decisions are always written up as PEPs, following the
|
||
existing process. The approver (formerly "BDFL-Delegate") is always
|
||
the CoA, and can no longer be delegated. Note that this does not
|
||
prevent the CoA from deciding to nominate a core developer to assess
|
||
the proposal and provide the CoA with a recommendation, which is
|
||
essentially the same as the current delegation process.
|
||
|
||
The CoA will pronounce on PEPs submitted to python-committers with a
|
||
request for pronouncement. Any member of the CoA, or the current RM,
|
||
may request changes to a PEP for any reason, provided they include
|
||
some indication of what additional work is required to meet their
|
||
expectations. See later sections for examples of expected reasons.
|
||
|
||
When all members of the CoA and the RM indicate that they have no
|
||
concerns with a PEP, it is formally accepted. When one or more members
|
||
of the CoA fail to respond in a reasonable time, the President of the
|
||
CoA may choose to interpret that as implied approval. Failure of the
|
||
President to respond should be handled using a vote of no confidence.
|
||
|
||
Election terms
|
||
--------------
|
||
|
||
Members of the CoA are elected for the duration of a release. The
|
||
members are elected prior to feature freeze for the previous release,
|
||
and hold their position until feature freeze for their release.
|
||
|
||
Members may seek re-election as many times as they like. There are no
|
||
term limits. It is up to the core developers to prevent re-election of
|
||
the CoA members where there is consensus that the individual should
|
||
not serve again.
|
||
|
||
Election voting process
|
||
------------------------
|
||
|
||
The election process for each member of the CoA proceeds as follows:
|
||
|
||
* a nomination email is sent to python-committers
|
||
* a seconding email is sent
|
||
* the nominee is temporarily added to python-committers for the
|
||
purpose of introducing themselves and presenting their position
|
||
* voting opens two weeks prior to the scheduled feature freeze of the
|
||
previous release
|
||
* votes are contributed by modifying a document in a private github
|
||
repository
|
||
* each core developer may add +1 votes for as many candidates as they
|
||
like
|
||
* after seven days, voting closes
|
||
* the nominee with the most votes is elected as President of the CoA
|
||
* the next three nominees with the most votes and also at least 50%
|
||
the number of votes received by the President are elected as the
|
||
other members of the CoA
|
||
* where ties need to be resolved, the RM may apply one extra vote for
|
||
their preferred candidates
|
||
* accepted nominees remain on python-committers; others are removed
|
||
|
||
No-confidence voting process
|
||
----------------------------
|
||
|
||
A vote of no confidence proceeds as follows:
|
||
|
||
* a vote of no confidence email is sent to python-committers, naming
|
||
the affected member of the CoA, justifying the nomination, and
|
||
optionally listing accepted PEPs that the nominator believes should
|
||
be reverted
|
||
* a seconding email is sent within seven days
|
||
* the nominated member of the CoA is allowed seven days to respond,
|
||
after which the nominator or the seconder may withdraw
|
||
* if no nominator or seconder is available, no further action is
|
||
taken
|
||
* voting opens immediately
|
||
* each core developer may add a +1 vote (remove the the CoA member) or
|
||
a -1 vote (keep the the CoA member) by modifying a document in a
|
||
private github repository
|
||
* after seven days, voting closes
|
||
* if +1 votes exceed -1 votes, the the CoA member is removed from
|
||
python-committers and any nominated PEPs are reverted
|
||
* if requested by the remaining members of the CoA, or if only one
|
||
member of the CoA remains, a new election to replace the removed
|
||
member may be held following the usual process.
|
||
* in the case of removing the President of the CoA, the candidate
|
||
who originally received the second-most votes becomes President
|
||
|
||
Examples of intended behaviour
|
||
==============================
|
||
|
||
This section describes some examples of the kind of interactions that
|
||
we hope to see between the CoA and the core developers. None of these
|
||
are binding descriptions, but are intended to achieve some consensus
|
||
on the types of processes we expect. The CoA candidates may campaign
|
||
on the basis of whatever process they prefer, and core developers
|
||
should allocate votes on this basis.
|
||
|
||
Scenario 1 - The Case of the Vague PEP
|
||
--------------------------------------
|
||
|
||
Often in the past, initial proposals have lacked sufficient detail to
|
||
be implementable by anyone other than the proposer. To avoid this,
|
||
the CoA should read proposals "fresh" when submitted, and without
|
||
inferring or using any implied context. Then, when an aspect of a PEP
|
||
is not clear, the CoA can reject the proposal and request
|
||
clarifications.
|
||
|
||
Since the proposal is rejected, it must be modified and resubmitted in
|
||
order to be reviewed again. The CoA will determine how much guidance
|
||
to provide when rejecting the PEP, as that will affect how many times
|
||
it will likely be resubmitted (and hence affect the CoA's own
|
||
workload). This ensures that the final PEP text stands alone with all
|
||
required information.
|
||
|
||
Scenario 2 - The Case of the Endless Discussion
|
||
-----------------------------------------------
|
||
|
||
From time to time, a discussion between Python contributors may seem
|
||
to be no longer providing value. For example, when a large number of
|
||
emails are repeating points that have already been dealt with, or are
|
||
actively hostile towards others, there is no point continuing the
|
||
"discussion".
|
||
|
||
When such a discussion is occurring on python-committers as part of a
|
||
request for pronouncement, a member of the CoA should simply declare
|
||
the thread over by rejecting the proposal. In most known cases,
|
||
discussion of this sort indicates that not all concerns have been
|
||
sufficiently addressed in the proposal and the author may need to
|
||
enhance some sections.
|
||
|
||
Alternatively, and in the absence of any rejection from the other
|
||
members of the CoA, the President may declare the thread over by
|
||
accepting the proposal. Ideally this would occur after directly
|
||
confirming with the rest of the CoA and the RM that there are no
|
||
concerns among them.
|
||
|
||
When such a discussion is occurring on another list, members of the
|
||
CoA should be viewed as respected voices similar to other core
|
||
developers (particularly those core developers who are the named
|
||
experts for the subject area). While none have specific authority to
|
||
end a thread, preemptively stating an intent to block a proposal is a
|
||
useful way to defuse potentially useless discussions. Members of the
|
||
CoA who voluntarily follow discussions other than on python-committers
|
||
are allowed to suggest the proposer withdraw, but can only actually
|
||
approve or reject a proposal that is formally submitted for
|
||
pronouncement.
|
||
|
||
Scenario 3 - The Case of the Unconsidered Users
|
||
-----------------------------------------------
|
||
|
||
Some proposals in the past may be written up and submitted for
|
||
pronouncement without considering the impact on particular groups of
|
||
users. For example, a proposal that affects the dependencies required
|
||
to use Python on various machines may have an adverse impact on some
|
||
users, even if many are unaffected due to the dependencies being
|
||
typically available by default.
|
||
|
||
Where a proposal does not appear to consider all users, the CoA might
|
||
choose to use their judgement and past experience to determine that
|
||
more users are affected by the change than described in the PEP, and
|
||
request that the PEP also address these users. They should identify
|
||
the group of users clearly enough that the proposer is able to also
|
||
identify these users, and either clarify how they were addressed, or
|
||
made amendments to the PEP to explicitly address them. (Note that this
|
||
does not involve evaluating the usefulness of the feature to various
|
||
user groups, but simply whether the PEP indicates that the usefulness
|
||
of the feature has been evaluated.)
|
||
|
||
Where a proposal appears to have used flawed logic or incorrect data
|
||
to come to a certain conclusion, the CoA might choose to use other
|
||
sources of information (such as the prior discussion or a submission
|
||
from other core developers) to request reconsideration of certain
|
||
points. The proposer does not necessarily need to use the exact
|
||
information obtained by the CoA to update their proposal, provided
|
||
that whatever amendments they make are satisfactory to the CoA. For
|
||
example, a PEP may indicate that 30% of users would be affected, while
|
||
the CoA may argue that 70% of users are affected. A successful
|
||
amendment may include a different but more reliable percentage, or may
|
||
be rewritten to no longer depend on the number of affected users.
|
||
|
||
Scenario 4 - The Case of the Delegated Decision
|
||
-----------------------------------------------
|
||
|
||
Some proposals may require review and approval from a specialist in
|
||
the area. Historically, these would have been handled by appointing a
|
||
BDFL-Delegate to make the final decision on the proposal. However, in
|
||
this model, the CoA may not delegate the final decision making
|
||
process. When the CoA believes that a subject matter expert should
|
||
decide on a particular proposal, the CoA may nominate one or more
|
||
individuals (or accept their self-nomination) to a similar position to
|
||
a BDFL Delegate. The terms of these expert's role may be set as the
|
||
CoA sees fit, though the CoA always retains the final approval.
|
||
|
||
As a concrete example, assume a proposal is being discussed about a
|
||
new language feature. Proponents claim that it will make the language
|
||
easier for new developers to learn. Even before an official proposal
|
||
is made, the CoA may indicate that they will not accept the proposal
|
||
unless person X approves, since person X has a long history teaching
|
||
Python and their judgement is trusted. (Note that person X need not be
|
||
a core developer.)
|
||
|
||
Having been given this role, person X is able to drive the discussion
|
||
and quickly focus it on viable alternatives. Eventually, person X
|
||
chooses the alternative they are most satisfied with and indicates to
|
||
the CoA that they approve. The proposal is submitted as usual, and the
|
||
CoA reviews and accepts it, factoring in person X's opinion.
