Automate CPE label update in release branch setup script

[dheerajodha]

What:

The release-branch-pipeline-patch.sh script now also updates the name and cpe labels in Dockerfile.dist, which were previously done as a separate manual PR for each release branch. The CPE version is accepted via the CPE_VERSION env var or an interactive prompt.

This change adds CPE label automation to the existing `hack/release-branch-pipeline-patch.sh`` script, so setting the name and cpe labels in Dockerfile.dist is no longer a separate manual step/PR during release branch setup.

How it works:

The script now prompts for the CPE version (a Red Hat product version, e.g. 1.5) or accepts it via the CPE_VERSION env var. It then updates Dockerfile.dist to change name="ec" to name="rhtas/ec-rhel9" and adds the cpe label.

Usage:

Interactive:

./hack/release-branch-pipeline-patch.sh
# Prompts: "Enter the CPE version for this release (e.g. 1.5): "

Non-interactive:

CPE_VERSION=1.6 ./hack/release-branch-pipeline-patch.sh

Previously this required a separate PR per release branch (e.g. #3184 for v0.8, #3529 for v0.9). Now it's handled automatically as part of the release branch pipeline setup.

Single-file, 36-line tooling script change automating a previously manual CPE label update step, with no protected paths, no security-sensitive content, and low churn history — all signals point to minimal risk.

• [portability] hack/release-branch-pipeline-patch.sh:112 — The sed replacement uses \n to inject a newline, but that is a GNU-sed–only extension. Bash double-quote processing turns the six backslashes + n into three backslashes + n sent to sed; GNU sed then collapses to \ + newline (correct Dockerfile line-continuation). BSD sed (macOS default, which release engineers may reasonably run this hack/ script on) does NOT interpret \n in the replacement as a newline, so Dockerfile.dist gets both labels concatenated on one physical line with a literal \n embedded inside the LABEL string. Worse, the follow-up grep -q "cpe:/a:redhat:trusted_artifact_signer:${TAS_VERSION}::el9" still finds the substring on that broken single line and reports success, so the script prints "Updated Dockerfile.dist labels" while having actually produced a malformed LABEL. The sed -i.bak form already used here suggests macOS compatibility was intended.
  Remediation: Either (a) use $'...' ANSI-C quoting so bash inserts a real newline before sed sees it (portable across GNU and BSD sed); or (b) require GNU sed explicitly (detect and error if sed --version fails); or (c) strengthen the post-check to anchor on the two-line form, e.g. grep -q '^ cpe="cpe:/a:redhat:trusted_artifact_signer:'"${TAS_VERSION}"'::el9"$' Dockerfile.dist.

Medium

• [error-handling] hack/release-branch-pipeline-patch.sh:99 — read -rp runs unguarded under set -o errexit. In a non-interactive context (CI, stdin redirected from /dev/null or closed) read returns a non-zero exit status on EOF, which under errexit terminates the script immediately with no output; the intended user-facing echo "Error: TAS version is required" at line 103 is never reached. Callers see a bare non-zero exit with no explanation.
  Remediation: read -rp "..." TAS_VERSION || true, or guard with if [[ -t 0 ]]; then read -rp ...; fi, so the subsequent [[ -z "$TAS_VERSION" ]] check runs and emits the informative error.

Low

• [correctness] hack/release-branch-pipeline-patch.sh:115 — grep -q "cpe:/a:redhat:trusted_artifact_signer:${TAS_VERSION}::el9" interpolates ${TAS_VERSION} (containing a literal .) into a BRE, where . matches any character. The ^[0-9]+\.[0-9]+$ validator makes a false positive essentially impossible in practice, but the fix is trivial.
  Remediation: Use grep -qF to treat the pattern as a fixed string.

• [description-implementation-mismatch] — The PR body states "The CPE version is accepted via the CPE_VERSION env var," but the script reads TAS_VERSION. The in-code comment justifies the TAS_VERSION name (TAS version does not necessarily follow the Conforma version), which is reasonable — but the PR description will mislead future readers grepping the merged history for CPE_VERSION.
  Remediation: Update the PR body to reference TAS_VERSION (and explain the TAS-vs-CPE distinction), or rename the env var to CPE_VERSION to match the body.

Info

• [scope-authorization-implicit] — Linked ticket EC-2154 is on Red Hat Jira and not reachable from this review environment, so authorization for the change cannot be verified directly. Authorization is inferred from PR title/body matching diff intent, scope confined to a single hack/ helper script used only during release branch setup, and labels size: XS and tooling being consistent with the change footprint.

• [provenance-warning] — Prior review context discarded: provenance validation failed (PRIOR_REVIEW_PROVENANCE=unverifiable-wrong-app). This review treats all findings as first-time assessments; no severity anchoring was applied.

• [error-handling] hack/release-branch-pipeline-patch.sh:112 — The sed substitution silently succeeds when the pattern name="ec" is not present in Dockerfile.dist (for example, on a re-run after a first successful patch, or if the Dockerfile.dist label style is later changed). Because set -e does not trip on a zero-substitution sed, the subsequent echo "Updated Dockerfile.dist labels:" block still prints as if the update succeeded, misleading the release engineer. This is also why the change is not re-runnable: an operator who enters the wrong TAS_VERSION cannot fix it by simply re-invoking the script (the first run destroyed the anchor pattern), and the misleading "Updated" output hides that fact.
  Remediation: After the sed call, verify the substitution took effect — e.g., grep -q "cpe:/a:redhat:trusted_artifact_signer:${TAS_VERSION}::el9" Dockerfile.dist || { echo "Error: failed to update Dockerfile.dist labels (pattern not found — file may already be patched, or the label format changed)"; exit 1; }.

Low

• [portability] hack/release-branch-pipeline-patch.sh:112 — sed -i'' is GNU-sed syntax (in-place edit, no backup). On BSD/macOS sed, -i requires its extension argument as a separate token (sed -i '' -e ...); the -i'' form is parsed differently and can consume the next argument, causing the script to fail or write unexpected files. The rest of the script is Linux-friendly, but this is the first sed -i introduced, so it is worth calling out.
  Remediation: If macOS support matters, use sed -i.bak -e ... && rm Dockerfile.dist.bak, or gate the flag on uname. Otherwise, document that the script is Linux-only.

• [output-format-consistency] hack/release-branch-pipeline-patch.sh:115 — The echo summary prints the name and cpe labels as two separate lines, but the actual sed substitution writes the cpe label as a continuation of the existing name= line (via \ + newline + indent, inside one logical LABEL directive). The user-facing summary does not match the shape of what was inserted; the rest of this script's echoes mirror the exact artifact they describe.
  Remediation: Print a single line reflecting the actual inserted form, or explicitly note the continuation, to stay consistent with the file's "echo what you did" style.

• [silent failure] hack/release-branch-pipeline-patch.sh:113 — The sed command will silently succeed even if name="ec" is not found in Dockerfile.dist (e.g., if the script is run a second time after the label was already renamed). The script will print the success message regardless. Optionally, add a post-sed grep -q 'name="rhtas/ec-rhel9"' Dockerfile.dist verification check.

• [portability] hack/release-branch-pipeline-patch.sh:113 — The sed replacement uses \n to insert a newline, which is a GNU sed extension. On macOS BSD sed, \n in the replacement string produces a literal backslash-n rather than a newline. This is likely fine since the script targets Linux release infrastructure, but a comment noting the GNU sed dependency would be helpful.

Lgtm, but consider splitting the sed replace into two separate commands.

[robnester-rh]

LGTM

[dheerajodha]

I don't care so much about the mac compatibility, but maybe two separate sed commands would make this easier to read.

Good point, I've pushed a new commit addressing this.
