# Veilid Release Process

## Introduction

Veilid is a monorepo consisting of several projects:  
(checked boxes are released as packages)

## Release Mechanism

Releases happen via a CI/CD pipeline. Builds and tests are automatic and must succeed before a release is triggered. Releases happen if a successful build pipeline off of the `main` branch runs, followed by test pipeline, followed by package pipeline. 

A new tag is calculated for each released artifact in the format 'name-v0.1.0', where the name is the pipeline name (veilid-server-deb-v0.0.0) for example. If the version number on the resulting output package artifact has changed from the most recent tag for that artifact, it is published. If publication is successful, the repository is tagged with the new tag. Multiple releases and tags can happen per pipeline run, if multiple version numbers are bumped in the same commit.

Tags serve as a historical record of what repo versions were successfully released at which version numbers.

## 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.

  > The base rust crate for Veilid's logic  
  > Released to crates.io when its version number is changed in `Cargo.toml`
- [ ] __veilid-server__ 
  > The Veilid headless node end-user application  
  > Not released to crates.io as it is an application binary that is either built by hand or installed using a package manager.  
  > This application does not currently support `cargo install`
- [ ] __veilid-cli__ A text user interface to talk to veilid-server and operate it manually
  > Not released to crates.io as it is an application binary that is either built by hand or installed using a package manager.  
  > This application does not currently support `cargo install`
- [ ] __veilid-wasm__
  > Not released to crates.io as it is not a library that can be linked by other Rust applications
- [ ] __veilid-flutter__ 
  > The Dart-FFI native interface to the Veilid API  
  > This is currently built by the Flutter plugin `veilid-flutter` and not released.

### Python Packages:

  > Released to PyPi when the version number is changed in `pyproject.toml`
  
### Flutter Plugins:
- [ ] __veilid-flutter__ 
  > The Flutter plugin for the Veilid API.  
  > Because this requires a build of a native Rust crate, this is not yet released via https://pub.dev  
  > TODO: Eventually the rust crate should be bound to
