Refactor GitHub Actions workflow to use environment variables - #547
Merged
Conversation
Release workflows pasted ${{ github.ref_name }} directly into run: blocks,
so the tag name was substituted into the shell source before bash parsed
it. Creating a tag or release needs write access, so this is defence in
depth rather than an open hole -- but it is the same defect robusta-gitops
fixed in ROB-1034 and it costs nothing to close.
Each affected step now reads the tag from a GITHUB_REF_NAME env var and
references only the quoted shell variable, matching the idiom the Windows
"Set version in code" step in this same workflow already used.
The awk version-rewrite previously spliced the tag into the awk *program*
text by closing and reopening the shell quoting; it now passes the tag as
an awk variable with -v, which is both safe and easier to read. The
needs.*.outputs build hashes move to env alongside it for consistency.
docker-build-on-tag.yml is unchanged: its ref_name uses are docker
build-push-action `tags:` inputs, not shell source.
## Tests performed
- Ran the original awk construct and the -v rewrite side by side against a
sample __init__.py with tag 1.7.1: output is byte-identical.
- Ran the rewrite with a tag of $(touch PWNED): the literal string is
written into the file and no command executes.
- Confirmed both workflows still parse as YAML and that no github.* or
needs.* interpolation remains in any run: block in the repo.

Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔴 Critical · up to A crafted release tag could alter build execution or produce malformed release metadata, while the workflow can also lose the tag between steps and publish empty checksums after hashing failures. These release-integrity and security issues make the PR unsafe to merge until fixed. Possibly related PRs

In @.github/workflows/build-on-release.yml:
- Around line 208-215: Persist TAG_NAME from the run step so it is available in
the later commit step’s separate shell; define it via the commit step’s env
block or write it to GITHUB_ENV while preserving the existing github.ref_name
value.
- Around line 173-175: Update the MAC_BUILD_HASH and LINUX_BUILD_HASH steps to
enable strict shell failure handling with set -euo pipefail, compute each
sha256sum separately, and append the resulting named values to GITHUB_OUTPUT
instead of using the deprecated set-output syntax. Preserve the existing archive
names and output names.
- Around line 66-70: Serialize the release tag before using it in generated
source or URLs: at .github/workflows/build-on-release.yml lines 66-70, pass
GITHUB_REF_NAME to awk as data and emit a safely serialized Python __version__
literal; apply the equivalent serialization in the related Windows
version-generation block at lines 76-78. At
.github/workflows/build-on-release.yml lines 208-215, pass TAG_NAME safely to
awk and restrict or URL-encode it before constructing formula URL path segments.

Summary
This PR refactors the build-on-release GitHub Actions workflow to use environment variables instead of directly interpolating GitHub context variables in shell commands. This improves security, readability, and reduces potential issues with special characters in variable values.
