# Veilid Release Process
## Introduction
2023-08-19 17:19:17 -05:00
This guide outlines the process for releasing a new version of Veilid. The end result is an update of the package repositories and Pypi.

## Create a Gitlab Release
2023-06-19 14:23:30 -05:00
2023-08-01 21:37:38 -05:00
Releases happen via a CI/CD pipeline. The release process flows as follows:
2023-08-19 17:19:17 -05:00
1. Complete outstanding merge requests (MR):
2023-09-12 08:43:09 -05:00
2023-08-19 17:19:17 -05:00
1.1 Evaluate the MR's adherence to the published requirements and if automatic tests passed.
2023-09-12 08:43:09 -05:00
2023-08-19 17:19:17 -05:00
1.2 (Optional) Perform the merge in a local dev environment if testing is required beyond the standard Earthly tests.
2023-09-12 08:43:09 -05:00
2023-08-19 17:19:17 -05:00
1.3 If everything checks out, MR meets the published requirements, and tests passed, execute the merge functions in the Gitlab UI.
2023-08-01 21:37:38 -05:00
2. Maintainer performs version bump:
2023-09-12 08:43:09 -05:00
2023-08-19 17:19:17 -05:00
2.1 Update your local copy of `main` to mirror the newly merged upstream `main`
2023-09-12 08:43:09 -05:00
2.2 Ensure the [CHANGELOG ](./CHANGELOG.md ) is updated
2023-08-19 17:19:17 -05:00
2.3 Activate your bumpversion Python venv (see bumpversion setup section for details)
2.4 Execute version_bump.sh with the appropriate parameter (patch, minor, or major). This results in all version entries being updated and a matching git tag created locally.
2.5 Add all changes `git add *`
2.6 Git commit the changes with the following message: `Version update: v{current_version} → v{new_version}`
2023-06-19 14:23:30 -05:00
2023-08-19 17:19:17 -05:00
2.7 Create the Git tag `git tag v{new_version}`
2023-09-12 08:43:09 -05:00
2023-08-19 17:19:17 -05:00
2.8 Push your local 'main' to the upstream origin 'main' `git push`
2023-09-12 08:43:09 -05:00
2023-08-19 17:19:17 -05:00
2.9 Push the new tag to the upstream origin `git push origin {tag name made in step 2.7}` i.e. `git push origin v0.1.5`
2023-09-12 08:43:09 -05:00
2023-08-19 17:19:17 -05:00
2.10 Ensure the package/release/distribute pipeline autostarted in the Gitlab UI
Git tags serve as a historical record of what repo versions were successfully released at which version numbers.
## Publish to Pypi
1. Change directory to veilid-python
2. Install Poetry and configure the Pypi credentials, if not already accomplished.
3. Execute `poetry build`
4. Execute `poetry publish`
2023-06-19 14:23:30 -05:00
## Reverting Releases
Occasionally a release will happen that needs to be reverted. This is done manually on `crates.io` or the APT repository, or wherever the artifacts end up. Tags are not removed.

### Version Numbering
2023-07-16 13:35:51 -05:00
2023-09-12 08:43:09 -05:00
All versions of Veilid Rust crates as well as `veilid-python` and `veilid-flutter` packages are versioned using Semver. Versions can differ per crate and package, and it is important for the Semver rules to be followed (< https: // semver . org /> ):
2023-07-16 13:35:51 -05:00
2023-09-12 08:43:09 -05:00
- MAJOR version when you make incompatible API changes
- MINOR version when you add functionality in a backward compatible manner
- PATCH version when you make backward compatible bug fixes
2023-07-16 13:35:51 -05:00
2023-07-16 14:04:00 -05:00
The `version_bump.sh` script should be run on every release to stable. All of the Rust crates are versioned together and should have the same version, as well as the `veilid-python` Python package and `veilid-flutter` Flutter plugin.

## Bumpversion Setup and Usage
2023-09-12 08:43:09 -05:00
2023-08-19 17:19:17 -05:00
### Install Bumpversion
2023-09-12 08:43:09 -05:00
2023-08-19 17:19:17 -05:00
1. Create a Python venv for bumpversion.py. Mine is in my home dir so it persists when I update my local Veilid `main` .
`python3 -m venv ~/bumpversion-venv`
2. Activate the venv. `source ~/bumpversion-venv/bin/activate`
3. Install bumpversion. `pip3 install bumpversion`
### Activate venv for version bumping step of the release process
