lrascao/rebar3_appup_plugin

This system is a Rebar3 plugin designed to automate the generation of application upgrade and downgrade scripts (.appup files) for Erlang releases. It specifically handles the automatic migration of gen\_server state records between versions, eliminating the need for manual intervention during release updates. The tool also provides infrastructure for managing release notes and includes a comprehensive test suite to verify version matching and instruction merging logic.

The plugin now automatically detects changes in gen\_server state records between release versions and injects the necessary migration code into the generated .appup files. This allows applications to upgrade and downgrade without manual intervention when the internal state structure of a gen\_server changes. The feature is implemented via the new \rebar3\_appup\_tar\ provider, which instruments the release to handle these migrations, and updates the \rebar3\_appup\_compile\ and \rebar3\_appup\_generate\ providers to identify and process state record differences.

The project license has been updated from MIT to Apache 2.0, and the continuous integration system has switched from Travis CI to GitHub Actions. The build configuration now enforces warnings as errors, includes the \string\_compat\ dependency alongside \bbmustache\, and adds a \pr2relnotes.sh\ script to generate release notes from pull requests.

The internal template system for generating application upgrade/downgrade scripts has been restructured. New templates in the priv/templates directory now handle state record conversion logic, specifically supporting the migration of state records between versions by mapping old and new field definitions and handling default values for new fields. Additionally, the appup template has been updated to use Mustache-style variable syntax (e.g., {{{new\_vsn}}}) for better escaping and clarity, and the generation process now merges pre- and post-source files into the final generated appup.

The \doc/euc-2016/js/remark-latest.min.js\ file has been added, providing the latest version of the remark.js library. This update ensures that the slide deck rendered in the browser uses the most current parsing and rendering capabilities for the EUC 2016 lightning talk materials.

Added Common Test (CT) and EUnit test suites to verify the rebar3 appup plugin's behavior. The CT suite (\rebar3\_appup\_plugin\_SUITE\) covers end-to-end release upgrade scenarios, including empty appups, supervisor and gen\_server state changes, dependency management, and \.appup.src\ scripting support. The EUnit tests (\rebar3\_appup\_plugin\_eunit\_tests\) validate the core version matching logic and instruction merging for upgrade/downgrade paths, ensuring correct handling of version patterns and post-condition filtering.

An empty file named 'include/keepme' was added to the repository. This change appears to be a placeholder or a mechanism to ensure the 'include' directory is tracked by version control, rather than a functional code change.
