# Release targets and helpers
#
# The following targets and macros are used to help start and cut releases.
# At high level, this involves:
# - Creating release branches
# - Adding empty commits to start next release, and updating the 'dev' tag
# - Adding 'release' tag to the commit that will be release
# - Creating an empty commit for the next potential patch release, and updating
#   the dev tag on that commit
# - Copying images for the released commit over to the release registries, and
#   re tagging those images with the release tag
#
# The following definitions will be helpful in understanding this process:
# - 'dev' tag: A git tag of the form of `v3.8.0-calient-0.dev-36-g3a618e61c2d3`
#   that every commit has. The start of the dev tag, i.e. v3.8.0, is the
#   the release that this commit will go into.
# - 'release' tag: A git tag of the form of `v3.8.0`. The commit that a release
#   is cut from will have this tag, i.e. you can find the commit that release
#   3.8 uses by finding the commit with the tag v3.8.0.
# - 'dev' image: The image that is created for every commit that is merged to
#   master or a release branch. This image is tagged with the dev tag, i.e.
#   if commit 3a618e61c2d3 is on master or a release branch, there will be
#   an image for that commit in the dev registry with the tag
#   `v3.8.0-calient-0.dev-36-g3a618e61c2d3`.
# - 'release' image: The public image the customers will use to install our
#   our product. Producing this is the goal of cutting the release. This image
#   will be in the release registries, and will be tagged with the release tag,
#   i.e. the release image for release 3.8 will have the v3.8.0 tag, or if it's
#   a patch release it will be v3.8.<patch version>

# Windows image pushing is different because we do not build docker images directly.
# Since the build machine is linux, we output the images to a tarball. (We can
# produce images but there will be no output because docker images
# built for Windows cannot be loaded on linux.)
#
# The resulting image tarball is then pushed to registries during cd/release.
# The image tarballs are located in WINDOWS_DIST and have files names
# with the format 'node-windows-v3.21.0-2-abcdef-20H2.tar'.
#
# In addition to pushing the individual images, we also create the manifest
# directly using 'docker manifest'. This is possible because Semaphore is using
# a recent enough docker CLI version (20.10.0)
#
# - Create the manifest with 'docker manifest create' using the list of all images.
# - For each windows version, 'docker manifest annotate' its image with "os.image: <windows_version>".
#   <windows_version> is the version string that looks like, e.g. 10.0.19041.1288.
#   Setting os.image in the manifest is required for Windows hosts to load the
#   correct image in manifest.
# - Finally we push the manifest, "purging" the local manifest.
