Pulumi Upgrade Provider

Pulumi Upgrade Provider

Overview

Run upgrade-provider --no-submit, fix known failures, and rerun until success. During the run loop, the tool owns branch and generated-commit state but does not push or mutate GitHub. After success, review and correct the local result before submitting it using the plan printed by the tool.

Preflight

1. Record existing changes as the pre-upgrade baseline:

baseline_file="${TMPDIR:-/tmp}/upgrade-provider-$(basename "$PWD")-baseline.txt"
git status --short --untracked-files=all | tee "$baseline_file"

Existing changes do not block the upgrade, but the tool stages broadly and may include them in generated commits. If practical, isolate clearly unrelated work in another branch or worktree, move local-only files, or add untracked local artifacts to .git/info/exclude. Otherwise proceed and carry this baseline into the final review. Do not add a repository .gitignore rule unless the path should be ignored for all contributors.

1. Keep the run log outside the repository so the tool cannot stage it.

Run Loop

1. Run from repo root:

log_file="${TMPDIR:-/tmp}/upgrade-provider-$(basename "$PWD").log"
upgrade-provider $ORG/$REPO --repo-path . --no-submit > "$log_file" 2> /dev/null

Preserve --no-submit on every retry.

1. Wait for completion (can take up to 10 minutes).
2. Check for errors by scanning the log for lines starting with error: :

if command -v rg >/dev/null 2>&1; then
  rg -n '^error: ' "$log_file" || true
else
  grep -n '^error: ' "$log_file" || true
fi

1. On a successful exit, first check whether the tool found that no upgrade was required:

if grep -Fq 'No actions needed' "$log_file"; then
  echo 'No actions needed'
fi

If present, report that the provider is already current or the requested target is not an upgrade, then stop successfully. There is no local upgrade to review or submit.

1. Otherwise, extract and read the complete local-completion report from the captured stdout:

awk '/^Upgrade completed locally;/{found=1} found' "$log_file"

This includes the proposed PR body and metadata, review commands, and every skipped submission action.

1. If failed, fix using this skill's references/upgrade-provider-errors.md (from the skill folder, not the repo), then rerun with --no-submit. If upstream migrated from Terraform Plugin SDKv2 to Plugin Framework, use the migration-guide routing in that reference instead of treating the framework change alone as an architectural blocker. For upstream go get failures involving ignored replace directives or unknown revision v0.0.0, rerun with --target-version after applying the documented provider/go.mod replacements; preserve the original major/non-major intent and add --major only for actual major version upgrades.
2. If a fix requires creating/amending/removing/rebasing patches, use the upstream-patches skill for the patch workflow. Interrupted patch workflows must be checked in before rerunning.
3. If you fixed a conflict, report exact edits (file paths + concrete changes or preserved intent).
4. Repeat until the tool prints No actions needed or the local-completion report and proposed PR plan. This run must not push or mutate GitHub; a branch or PR from an earlier run may already exist.

When to Stop and Report Failure

Stop iterating and report failure if any of these conditions are met:

1. Command not found (exit code 127): The upgrade-provider tool is not in PATH.
2. Same error 3 times: You've attempted to fix the same error 3 times without success.
3. Unknown error pattern: The error is not covered in references/upgrade-provider-errors.md and you cannot determine a safe fix.
4. Ambiguous patch state: You cannot prove that every patch was applied and the target rebase completed.
5. Requires human judgment: The fix needs user input, such as choosing between multiple valid implementation approaches or making an architectural decision about module organization. Upstream breaking changes, deprecations, or framework migrations do not by themselves require stopping; stop only when implementing the upgrade presents an unresolved choice.

When stopping, report:

1. The error(s) encountered.
2. What fixes were attempted (with file paths and changes).
3. Why human intervention is needed.
4. Any partial progress.

Review the Local Upgrade

Use the tool's final report as the source of truth for the base branch, working branch, proposed PR title/body/metadata, and skipped submission actions.

1. Review a bounded summary first:

default_branch=$(gh repo view --json defaultBranchRef --jq .defaultBranchRef.name)
base_ref="origin/$default_branch"
git status --short --untracked-files=all
git log --oneline "$base_ref"..HEAD
git diff --shortstat "$base_ref"...HEAD
git diff --name-only "$base_ref"...HEAD | awk -F/ '{print $1}' | sort | uniq -c

Provider upgrades can change thousands of generated SDK files. Do not print the full branch diff by default. Use path-limited git diff "$base_ref"...HEAD -- <paths> commands to inspect source, configuration, patch, schema, and unexpected directories. For generated SDKs, inspect summaries or targeted files unless a full diff is necessary.

Cross-check the final branch against the pre-upgrade baseline:

baseline_file="${TMPDIR:-/tmp}/upgrade-provider-$(basename "$PWD")-baseline.txt"
[ ! -f "$baseline_file" ] || cat "$baseline_file"

For every pre-existing path included in the branch, decide whether it belongs in the upgrade PR. Keep intentional paths; move unrelated work to another branch/worktree or remove it from the unpublished upgrade history before pushing. A separate commit on the same branch isolates history but does not remove the path from the PR, and unstaging alone is insufficient after the tool has committed it. Revoke any exposed credential even if the history is rewritten.

1. MUST audit generated doc replacements for unresolved placeholders before publication:

if [ -f provider/replacements.json ]; then
  if command -v rg >/dev/null 2>&1; then
    rg -n '"new":.*TODO|TODO' provider/replacements.json || true
  else
    grep -En '"new":.*TODO|TODO' provider/replacements.json || true
  fi
fi

If any TODO is found in provider/replacements.json:

• Treat it as a pre-submission blocker; replacement values render into generated docs.
• Inspect each old/new pair and replace TODO with concrete Pulumi-facing wording, usually Pulumi, this provider, or the provider.
• Run focused validation if the repo has the test:

cd provider && go test -v -run TestReplacementDoesNotIncludeTodos .

1. If the upgrade changed patches, review the applied commits and then exit checkout mode:

./scripts/upstream.sh checkout
git -C upstream log --oneline pulumi/checkout-base..pulumi/patch-checkout
# Inspect relevant commits with git -C upstream show <sha>.
./scripts/upstream.sh check_in

List commit SHAs/titles, summarize each intent, and call out behavioral changes or risks. check_in is mandatory after review; leaving upstream on pulumi/patch-checkout blocks the next safe tool run.

1. Run focused validation for every manual fix and add focused follow-up commits.
2. Require a clean working tree before submission.

Submit the Reviewed Upgrade

The local-completion report lists the proposed PR metadata and every skipped action. MUST reproduce all applicable actions, not only PR creation:
