release.pre.rst

Overview

`release.pre.rst` is a release announcement template file used by the Pytest development team to communicate details about a prerelease version of Pytest. This file serves as a pre-formatted message that informs users about the availability of a prerelease, its purpose, upgrade instructions, contribution acknowledgments, and relevant links for documentation and issue reporting.

This file is typically rendered and published as part of the release process to keep the community informed and engaged in testing upcoming features before the final official release.

File Purpose and Functionality

Purpose: To provide a standardized, clear, and informative prerelease announcement for a specific version of Pytest.
Functionality: As a reStructuredText (RST) template, it incorporates placeholders (such as {version}, {doc_version}, and {contributors}) that are dynamically replaced with actual values during the release automation or manual release preparation process.
Output: A formatted announcement that can be posted on documentation sites, mailing lists, or project repositories to notify users about the prerelease and encourage testing and feedback.

Detailed Explanation of the File Structure and Placeholders

This file is not a code file containing classes or functions but rather a text template with embedded placeholders. The placeholders are meant to be substituted with real values during the release process.

Template Sections and Their Roles

Section	Description	Placeholders Used
Title	Displays the package name and version.	{version}
Introductory Announcement	Announces the prerelease and clarifies its intended use (testing, not production).	{version}
Call to Action	Encourages users to report issues and how to do so.	None
Upgrade Instructions	Provides the exact command to upgrade/install the prerelease version via pip.	{version}
Documentation Link	Points users to the changelog for detailed changes in this version.	{doc_version}
Contributors Acknowledgement	Lists contributors who helped with the release.	{contributors}
Closing Remark	A friendly sign-off from the Pytest team.	None

Placeholders Explained

{version}: The prerelease version string, e.g., 7.3.0rc1.
{doc_version}: The documentation version that corresponds to the prerelease, used in URLs.
{contributors}: A formatted list or string of contributors who participated in the release.

Usage Example

During the release preparation, a release engineer or automation script would replace the placeholders with actual values. For example:

pytest-7.3.0rc1
=======================================

The pytest team is proud to announce the 7.3.0rc1 prerelease!

This is a prerelease, not intended for production use, but to test the upcoming features and improvements
in order to catch any major problems before the final version is released to the major public.

We appreciate your help testing this out before the final release, making sure to report any
regressions to our issue tracker:

https://github.com/pytest-dev/pytest/issues

When doing so, please include the string ``[prerelease]`` in the title.

You can upgrade from PyPI via:

    pip install pytest==7.3.0rc1

Users are encouraged to take a look at the CHANGELOG carefully:

    https://docs.pytest.org/en/7.3.0rc1/changelog.html

Thanks to all the contributors to this release:

Alice, Bob, Charlie

Happy testing,
The pytest Development Team

This output can then be published to the project site or sent as an announcement.

Implementation Details and Algorithms

The file itself contains no executable code or algorithms.
It acts as a static template with placeholders that are expected to be substituted by external tooling during the release workflow.
The release automation pipeline or release manager will typically use scripts (e.g., Python scripts or shell scripts) to inject the correct version numbers and contributor lists into this template.

Interactions with Other Parts of the System

Release Automation Scripts: These scripts populate the placeholders with the current prerelease version and contributor information.
Documentation System: The generated announcement is often integrated into the official Pytest documentation or website.
Issue Tracker: The announcement references the GitHub issue tracker for reporting prerelease regressions.
Package Distribution System (PyPI): The announcement instructs users how to install the prerelease from PyPI.
Changelog Documentation: The announcement links to the changelog section of the documentation site, which is version-specific.
