name: Release Upload
# Pipeline to download binaries from Hydra builds and create GitHub
# releases out of them (or attaching the binaries to an already existing release)
#
# This pipeline is divided in three jobs:
#
# 1. The "wait_for_hydra" job looks up the status of the Hydra build corresponding to
# the tag for which we want to release. If the status is success, the pipeline
# continues. If the status cannot be determined or is a failure, the pipeline stops.
# 2. The "pull" job downloads the binaries from the Hydra build and uploads them as artifacts.
# This job uses a matrix to handle all 3 platforms. Uploading as an artifact allows to
# do the last job without a matrix.
#
# This job uses `--builders "" --max-jobs 0` to ensure the assets are downloaded
# from the IOG cache.
# 3. The "create_release" job downloads the artifacts and attaches them to the target release.
#
# This pipeline is triggered in one of the following 3 ways:
#
# 1. When a release is published, this release's commit must have a tag for the pipeline to succeed
# 2. When a tag is pushed. If this tag has a corresponding release, the release will be augmented.
# If there is no release, it will be created.
# 3. By launching it manually, optionally specifying the tag to release:
# gh workflow run "Release Upload" -r $(git branch --show-current) -f target_tag=cardano-cli-8.22.0.0
# This mode is not supported by the pipeline of cardano-node (which was copied to create this pipeline),
# but we anticipate this mode to be useful when debugging, or releasing a posteriori.
#
# If the tag is not specified, this pipeline will run, but skip the final "create_release" job,
# so no release will get created. This is useful for debugging or
# trying to build a release before tagging it.
#
# So far this pipeline supports releasing Linux and Darwin binaries.
# Please see the "TODO generalize" comments in this file to support new platforms.
