The Deploy_All_Services pipeline has offered scale-qa2 as an environment since 82f073a, but get_deployed_commit.py only recognized dev-scale, scale-test and scale-qa. Selecting QA2 failed the Summarize job with "Unknown environment 'scale-qa2'", which skipped the dependent Deploy job. - Map scale-qa2 to a QA2_BASE_URL environment variable, alongside the existing three - List scale-qa2 in the unknown-environment and empty-BASE_URL error messages - Document scale-qa2 in the script docstring and the Scripts/README.md row - Mention QA2 in the pipeline's environment parameter displayName Verified by running the script against scale-qa2 with QA2_BASE_URL set to https://qa2-admin.nhsnlink.org, which resolved the deployed commit 78b98b4 from /api/info. Unknown environments and the direct https:// URL argument are unchanged. Requires a QA2_BASE_URL variable to be added in Azure DevOps wherever QA_BASE_URL is already defined; without it the script reports the empty-BASE_URL error rather than querying the wrong host.
get_deployed_commit.py read the full SHA from payload.commit.sha2 in the JSON served
by the GitHub commit page. That path no longer exists — the SHA moved to
payload.commitRoute.commit.oid — so the chained .get() calls fell back to the short
hash and returned it without raising. The "Attempting to translate..." line was
therefore followed by neither a warning nor a translation.
FromCommit then reached list-deploy-changes.py as a 7-character hash. It fetches both
refs with 'git fetch --depth=1 origin <ref>', which GitHub rejects for anything but a
full SHA ("couldn't find remote ref"), and that fetch discards stderr and ignores its
exit code, so the deployment summary could silently come out empty.
- Query api.github.com/repos/.../commits/<sha> with the 'application/vnd.github.sha'
media type, which returns the 40-character hash as plain text, instead of reading
the commit page's undocumented JSON payload
- Accept the result only when it is exactly 40 characters, warning with the response
body otherwise
- Warn explicitly when FromCommit is still a short hash, naming the fetch that will
fail, so a future breakage is not silent
Verified against qa and qa2: 78b98b4 now resolves to
78b98b4. An unknown hash returns HTTP 422, which
raises into the existing handler and then trips the short-hash warning.

Neither urlopen call passed a timeout, and the script never sets a global socket default, so both used urlopen's default of blocking indefinitely. An unresponsive /api/info endpoint or GitHub API would hang the Summarize job until the Azure DevOps job timeout killed it, rather than failing the step with a usable error. - Add an HTTP_TIMEOUT_SECONDS constant of 30 seconds - Pass it to the /api/info request and the GitHub commits request, so both share the same budget A timeout on the /api/info call raises into the existing handler and exits through fail(); a timeout while resolving the full hash prints the existing warnings and leaves FromCommit as the short hash. Verified against qa2 that the normal path is unaffected: 78b98b4 still resolves to 78b98b4.
…esolved The script warned about an unresolved short hash and then published it anyway. The downstream consumer cannot use it: list-deploy-changes.py fetches both refs with 'git fetch --depth=1 origin <ref>', GitHub rejects unadvertised objects by short SHA, and that fetch discards stderr and ignores its exit code — so the deployment summary came out empty with nothing in the log to explain it. - Replace the short-hash warning with a fail(), reporting the same context on stderr and exiting nonzero - Place it ahead of the FromCommit print and the ##vso[task.setvariable] line, so no unusable value is published This makes the Summarize job fail whenever the GitHub lookup fails for any reason, including a rate limit or transport error, and Deploy is gated on Summarize succeeding. Verified against qa2 that the normal path is unchanged and exits 0. Forced the failure path with an unreachable API host: the warning and the ERROR line are both printed, the exit status is 1, and neither FromCommit nor the ##vso line is emitted.

That path no longer exists — the SHA moved topayload.commitRoute.commit.oid— so the chained.get()calls fell back to the short hash and returned it without raising.

The only behavioral change for

Ran the script directly against the live environments:
scale-qa2withQA2_BASE_URL=https://qa2-admin.nhsnlink.org→ resolvedBASE_URL, queried/api/info, and emittedFromCommit: 78b98b437a1dfcb748df590cda3cc53eae67edf9with the matching##vso[task.setvariable]line.scale-qawithQA_BASE_URL=https://qa-admin.nhsnlink.org→ same full hash, confirming the fix applies to the existing environments and not just QA2.bogus) →Unknown environment 'bogus'. Expected one of: dev-scale | scale-test | scale-qa | scale-qa2, or a direct https:// URL.BASE_URLerror naming all four variables.https://URL argument path is unchanged and still bypasses the environment mapping.Supporting checks for the hash fix:
{"meta": ..., "payload": {"commitRoute": {"commit": {"oid": "78b98b437a1dfcb748df590cda3cc53eae67edf9", ...}}}}with HTTP 200, which is why no exception was ever raised.git fetch --depth=1 origin 7fd1a60fails withcouldn't find remote ref, while the same fetch with the full 40-character SHA succeeds.py_compileclean.The pipeline itself has not been run with these changes; the Summarize job's behavior is inferred from the script's exit codes and the job dependency.
🧑🔬 Unit Testing
Justification: the deploy-support scripts under
Scripts/have no unit-test harness — the only Python tests in the tree areScripts/AzureAppConfig/tests/, covering the app-config tooling, and no CI workflow executes tests for this script. Both changed paths depend on live HTTP endpoints (a deployed/api/infoand the GitHub API) and were verified manually against them, as described above.📓 Documentation Updated
