# Script to merge the outputs of a run on github actions to github releases.
# This is invoked from `.github/workflows/publish-artifacts.yml`. All previous
# artifacts from builds are located in `bins-*` folders. The main purpose of
# this script is to take the "min" build and merge it into the "normal" build to
# produce one final tarball. This means that the final artifacts will have both
# a normal and a min build in them for comparison and usage.
set -ex
# Prepare the upload folder and move all artifacts that aren't being merged into
# this folder, e.g. the MSI installer and adapter wasm files.

# Merge tarballs and zips by searching for `*-min` builds, unpacking the
# min/normal builds, into the same destination, and then repacking into a
# tarball.
#
# Note that for now xz compression is used for the final artifact to try to get
# small artifacts, but it's left at the default level since a lot of artifacts
# are processed here and turning it up to the max 9 compression might take
# quite awhile on CI for this one builder to process.
