Task

You need to help unblock a dependency update.

The user should give you a PR number.

PR_NUMBER=... # e.g. 6133

Triage the build failure

The first thing to do is to inspect the build failure.

You can determine the commit SHA with:

COMMIT_SHA=$(gh pr view "$PR_NUMBER" --json commits --jq '.commits[-1].oid')

You can enumerate the failed build IDs with:

FAILED_BUILDS=$(gcloud builds list \
    --project=rust-sdk-testing \
    --region=us-central1 \
    --filter="status='FAILURE'" \
    --limit=100 \
    --format="json" | jq -r --arg SHA "$COMMIT_SHA" '.[] | select(.substitutions.COMMIT_SHA == $SHA) | .id')

You can look at the last lines of output with:

BUILD_ID=${FAILED_BUILDS[0]} # Typically one build is sufficient.
gcloud builds log "$BUILD_ID" --project=rust-sdk-testing --region=us-central1 | tail -n 200

In the output, identify the specific command that failed, and why. e.g. a

cargo test -p google-cloud-<package>.

Checkout the code

gh pr checkout ${PR_NUMBER}

Fix the build failure

Reproduce the build failure locally. Then iteratively fix the error.

When the command succeeds, report success!

Report success

Explain the changes and show the diff to the user.

Determine a good commit message for the changes.

COMMIT_MSG=... # e.g. "update foo to be more like bar"

Determine the upstream branch we checked out.

BRANCH=$(git branch --show-current)

Suggest to the user how to commit the changes and push them upstream. e.g.:

> To commit these changes and push them to the dependabot branch, run:

> `

> git commit -m "${COMMIT_MSG}" .

> git push upstream HEAD:${BRANCH}

> `
