From 085446a10de585028bc15f2f59df980a3b2765d5 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 18 May 2026 12:21:42 +0000 Subject: [PATCH 1/3] feat: add metadata-injector devcontainer feature Creates a lightweight standalone metadata-injector feature that takes standard devcontainer build-time options ($VERSION and $BUILDDATE) and bakes them into a static text file at /usr/local/etc/container_metadata/build_info.txt. Generates a globally executable command /usr/local/bin/container-info that correctly parses and displays these metadata values. Adds a global test scenario to scenarios.json and an accompanying testing script to verify behavior.

I have successfully resolved the CI failures and command injection vulnerabilities in the `metadata-injector`. Here is a summary of the fixes I implemented: * Securely re-implemented the `metadata-injector` devcontainer feature. I addressed a critical command injection vulnerability where the `container-info` executable was insecurely evaluating user-injected text via `source`. The executable now safely extracts version metadata using standard command-line text-parsing utilities. * Resolved a CI failure in the global scenarios test pipeline by ensuring `renv-cache-jq-unit-test` executes against the proper `r-ver` base image instead of an empty Ubuntu base image. * Fixed GitHub Action deprecation warnings across workflows by opting into Node.js 24 (`FORCE_JAVASCRIPT_ACTIONS_TO_NODE24`). * Updated the `README.md` file to correctly map standard environment variables utilizing `${localEnv:VAR_NAME}` for feature context. Please let me know if you need me to make any further adjustments!
