Release Notes

Publishing new package without any changes to pre-built libvips package

Bump version and push to master branch
Create new release at: https://github.com/akash-akya/vix/releases Github Actions and TravisCI creates pre-compiled NIF artifacts and push to the release. Wait for all the release to be available. Ensure artifacts are created for all Beam NIF versions, like 2.16, 2.17
Ensure all pre-built NIF packages are created
On local machine, remove existing pre-built NIF packages, cache and checksum rm -rf cache/ priv/* checksum.exs
Remove existing compiled files rm -rf _build/*/lib/vix
Generate checksum.exs by running: ELIXIR_MAKE_CACHE_DIR="$(pwd)/cache" MIX_ENV=prod mix elixir_make.checksum --all This downloads all available artifacts and generates checksum.exs file based on it. Check checksum file contents
Run test to ensure pre-built package pass the test ELIXIR_MAKE_CACHE_DIR="$(pwd)/cache" mix test
Publish Hex package. mix hex.publish

Pre-built libvips are built by our fork with few changes to compile a shared library which works with C codebase.

Pull latest stable upstream changes
Apply patches related to compile shared library compatible with C codebase from our repo
Create a tag matching upstream and push. Ensure tag commit matches the upstream and not set on the latest master to avoid issues
Once tag is pushed Github Actions creates a new release and creates artifacts
Check if all required artifacts are created
Update release_tag in the precompiler.exs
Test locally by setting export VIX_COMPILATION_MODE=PRECOMPILED_LIBVIPS. You might have to delete old cache and build artifacts -- rm -rf _build/*/lib/vix cache/ priv/* checksum.exs
Push changes to master and publish new release to Hex same as above
