The development process Twisted has adopted is this:
- Commits to trunk/ must be the result of the review process outlined below.
The only exception to this is the Twisted.Quotes file. There are no other exceptions.
- Changes to Twisted must be accompanied by a ticket in the tracker.
- Changes must be reviewed by a developer other than the author of the changes.
If changes are paired on, a third party must review them. If changes constitute the work of several people who worked independently, a non-author must review them.
- A reviewer can be anyone who is familiar with the Twisted codebase, coding
standard, and review requirements. A reviewer need not necessarily be familiar with the specific area of Twisted being changed, but he or she should feel confident in his or her abilities to spot problems in the change.
- A reviewer must reject a set of changes in any of the following
- The test suite fails on any of the supported* platforms as a result of the
- The changes alter the behavior of code in a way which is not tested.
- The changes add new behavior without adding test coverage for that
- The changes modify public APIs which are undocumented (ie, a function which
has no docstring is modified, or a class which has no docstring has methods added to it).
- The changes modify the behavior of a documented API without updating the
- The changes violate the coding standard.
- A reviewer may reject a set of changes for other reasons, most of which are
hard to quantify. Basically, use your best judgement, and don't be afraid to point out problems which don't fit into the above list.
- After a reviewer has given a change set the okay, the author (or another
developer, if the author is so inclined or lacks commit privileges) may commit the change set to trunk.
- The trunk commit must include the name of the author or authors, reviewer or
reviews, and the tickets which are being resolved by the changes being committed. The suggested format for this is:
Author: <names> Reviewer: <names> Fixes #<ticket number>
Only the "Fixes" line actually *needs* to conform to this (since it is
automatically processed in order to update the ticket's state in the tracker). The commit message should also describe the change being made in a modest amount of detail. This should be detailed enough for someone doing a release to formulate a changelog entry.
- If a change set somehow introduces a test suite regression or is otherwise
found to be undesirable, it is to be reverted. Any developer may revert a commit which introduces a test suite regression on a supported platform.
- If a branch is used, it should be deleted a short time after after it is
merged into trunk (leaving enough time for the buildslaves to run to completion is a good idea, in case a regression has been introduced and the merge must be reverted).
