…OPS-1318)
javadocs.liquibase.com is served from Cloudflare R2, but this workflow only ever
wrote to the S3 origin. The one thing carrying those files across was Sippy, a
lazy copy-on-first-read bridge that liquibase-infrastructure#4391 removes. With
Sippy gone and no R2 write here, the next release would land in S3 and never
reach the edge, freezing the published javadocs silently until someone noticed.
That is the TECHOPS-805 failure mode the Wave 3 epic exists to unwind.
Adds an R2 sync alongside the existing S3 one, reusing the pattern already proven
in liquibase-pro publish-to-s3.yml: load CLOUDFLARE_ACCOUNT_ID and the R2 S3-API
key pair from the devops vault via the org-level DEVOPS_VAULT_OIDC_ROLE_ARN,
pulling only those three keys and masking them rather than importing the vault.
Two details that are easy to get wrong against R2:
* env -u AWS_SESSION_TOKEN - the step runs under an assumed role, and R2 does
not recognise that session token, so SigV4 fails if it is left set.
* --checksum-algorithm CRC32 - the newer AWS CLI default checksum trailer is
not supported by R2.
S3 is kept deliberately. The origin bucket retires on its own ticket
(TECHOPS-876), and writing both means javadocs publish correctly whether or not
the Sippy removal has applied yet. Drop the S3 line with the bucket.
Measured before this change: the S3 origin held 3,673 objects against 3,265 in
R2, so 408 had never been lazily copied - whole trees including
liquibase-maven-plugin, liquibase-cdi-jakarta, liquibase-cdi and liquibase-cli. A
Super Slurper pass has since closed that gap; this change keeps it closed.

… S3 path (TECHOPS-1318)
Strict review found the first version introduced a regression with a much wider
blast radius than the problem it solved.
The R2 credential steps sat ahead of the S3 sync, so any hard failure in them - a
rotated /vault/devops key, an unassumable devops role - exited the job before
javadocs reached S3 at all, a path that works today. Worse,
release-published-orchestrator.yml gates deploy-maven on this job's result
(needs.deploy-javadocs.result == 'success' || 'skipped'), so a red javadocs job
SKIPS the Maven Central deployment for that release, and the orchestrator's final
check_stage marks the whole release failed.
Restructured so the existing path cannot regress:
* Steps 1-5 are byte-identical to main. The S3 sync carries no continue-on-error
and no if:, so its behaviour is unchanged.
* All three R2 steps now come AFTER it and are continue-on-error, each gated on
the previous one succeeding.
* A broken R2 leg degrades to stale javadocs plus a ::warning::, never a failed
release.
Also from the same review: the credential-loading step now mirrors the escaping
the existing vault step in this file deliberately uses. That step's own comment
explains why - the runner unescapes %0D, %0A and %25 in command data, so a value
carrying those literals registers a mask that never matches it. The first version
used the simpler form from publish-to-s3.yml and lost that hardening.
The pre-flight credential guard also moved ahead of the write it guards, instead
of sitting after it.

[high] This guard misses the failure it exists for: give the publish step an id and add it to the condition, otherwise a failed aws s3 sync goes green and silent.
Publish javadocs to Cloudflare R2 is continue-on-error: true and carries no id, so this if: can only ever catch credential problems. When the sync itself fails (wrong bucket, SigV4 rejection, R2 5xx, token scope) both r2-auth and r2-creds are still success, this step is skipped, and the job reports green with javadocs in S3 only.
That is the TECHOPS-805 failure mode this PR exists to prevent, and it matters more than usual because liquibase-infrastructure#4391 removes Sippy on the strength of this workflow working. The stated contract, "a broken R2 leg degrades to stale javadocs and a warning, never a failed release", holds for credentials but not for the publish.

That needs id: r2-publish added to the publish step at line 151 to resolve.

Confirmed and fixed in 0505a32.
You are right that the guard could only ever catch credential problems. Added id: r2-publish to the publish step and included its outcome in the condition, exactly as suggested.
Worth recording why the id was the missing piece: continue-on-error rewrites the step's conclusion to success but leaves its outcome as failure, so without an id there is nothing to read the real result from.
One note on the shape. A skipped publish also has a non-success outcome, so steps.r2-publish.outcome != 'success' on its own would subsume the other two clauses. I kept all three because they document what can actually go wrong, and added a comment saying so.
Review by sayaliM0412 on PR #8004, same finding from coderabbitai. The publish step is continue-on-error and had no id, so the warn step could only ever catch credential problems. When the sync itself fails, from a wrong bucket, a SigV4 rejection, an R2 5xx or a token scope, both r2-auth and r2-creds are still success, the warn step is skipped, and the job reports green with javadocs in S3 only. That is exactly the TECHOPS-805 failure mode this PR exists to prevent, and it matters because liquibase-infrastructure#4391 removes Sippy on the strength of this workflow working. continue-on-error rewrites a step's conclusion to success but leaves its outcome as failure, so reading the real result needs an id. Adds id: r2-publish and includes its outcome in the condition. A skipped publish also has a non-success outcome, so that clause alone would cover the credential cases too; the other two are kept for legibility. Refs: TECHOPS-1318, TECHOPS-805
…HOPS-921) liquibase-infrastructure#4397 decommissions javadocsliquibasecom-origin and the IAM grants that let this workflow write to it. With that bucket gone, the "aws s3 sync . s3://javadocsliquibasecom-origin" step and the vault/build-logic credential chain that only existed to reach it are dead weight, and a plain run step failing there would take deploy-maven and release-docker down with it through the orchestrator's needs graph. Removes the S3 sync line and the three steps that fetched credentials for it (Configure AWS credentials for vault access, Get secrets from vault, Configure AWS credentials). The Cloudflare R2 publish added in #8004 becomes the only target; its continue-on-error behavior is unchanged, so a broken R2 leg still degrades to a warning instead of failing the release. Updates the three README.md lines that described the old S3 destination.
Why?
javadocs.liquibase.comis served from Cloudflare R2, but this workflow only ever wrote to the S3 origin. The only thing carrying those files across was Sippy, a lazy copy-on-first-read bridge that liquibase-infrastructure#4391 removes.With Sippy gone and no R2 write here, the next release would land in S3 and never reach the edge — javadocs would silently freeze at whatever was last copied. That is the TECHOPS-805 failure mode the Wave 3 epic exists to unwind, and it would not surface until someone noticed stale docs weeks later.
I found this while auditing something else, which is worth saying plainly: without it, #4391 would have shipped a silent regression.
Evidence
Measured before the fix: the S3 origin held 3,673 objects against 3,265 in R2, so 408 had never been lazily copied — whole trees including
liquibase-maven-plugin,liquibase-cdi-jakarta,liquibase-cdiandliquibase-cli, plus the rootindex.html. A Super Slurper pass has since closed that gap; this change is what keeps it closed.What changed
Adds an R2 sync alongside the existing S3 one, reusing the pattern already proven in
liquibase-pro's ownpublish-to-s3.yml:DEVOPS_VAULT_OIDC_ROLE_ARN, loadCLOUDFLARE_ACCOUNT_IDplus the R2 S3-API key pair from the devops vault. Only those three keys, masked — no bulk import of the vault into the job.continue-on-error. Steps 1-5 are byte-identical tomain; the S3 sync carries nocontinue-on-errorand noif:, so the path that works today cannot regress.::warning::, never a failed release.Why that ordering matters
Review caught that the first version put the R2 credential steps ahead of the S3 sync, which made the working S3 publish newly dependent on R2 credential availability. Worse,
release-published-orchestrator.ymlgatesdeploy-mavenon this job's result, so a red javadocs job skips the Maven Central deployment for that release and the orchestrator marks the release failed. The blast radius of the fix was larger than the bug.Two details that are easy to get wrong against R2, both learned the hard way today:
env -u AWS_SESSION_TOKEN--checksum-algorithm CRC32S3 is kept on purpose
The origin bucket retires on its own ticket (TECHOPS-876). Writing to both means javadocs publish correctly whether or not the Sippy removal has applied yet, so this PR and #4391 are not order-dependent. Drop the S3 line together with the bucket.
No companion PR
I originally opened liquibase-pro#4980 with the same change, on the reasoning that the byte-identical file meant two live publishers. That was wrong and it is now closed:
core/.github/workflows/is not an executable path (Actions only reads the repo root, and liquibase-pro has no root copy), andcore/is subtree-synced from here daily. This PR propagates on its own.Testing
bash -n.env -uandCRC32flags are the same ones I used to list and Slurp these buckets successfully today, so they are verified against the live bucket rather than copied on faith.if: inputs.dry_run == falseand gated behind thereleaseenvironment. First real exercise will be the next release, so worth a second pair of eyes on the credential wiring.Refs: TECHOPS-1318, TECHOPS-923, TECHOPS-876, TECHOPS-917
