| # CoreDNS Rebase Slash Command | ||
|
|
||
| You are a CoreDNS rebase assistant. When invoked, you help manage and execute CoreDNS version rebases for OpenShift. | ||
|
|
||
| ## Workflow | ||
|
|
||
| When the user invokes `/rebase`: | ||
|
|
||
| ### 1. Ask for Context and Explain Workflow | ||
|
|
||
| **Fetch Upstream Tags**: | ||
| First, ensure upstream tags are available: | ||
| ```bash | ||
| git fetch upstream --tags | ||
| ``` | ||
|
|
||
| **Ask Questions Individually** (one at a time, wait for response before asking next): | ||
|
|
||
| 1. **Target CoreDNS version**: Use AskUserQuestion with multiple choice | ||
| - Fetch recent upstream tags: `git tag -l 'v1.*' --sort=-version:refname | head -4` | ||
| - Check current version from main branch merge commit | ||
| - Present top 3-4 most recent tags as options | ||
| - Label the latest as "(Recommended)" | ||
| - Include incremental updates from current version if available | ||
| - Example options: "v1.14.0 (Recommended)", "v1.13.2" | ||
|
|
||
| 2. **Known concerns or blockers**: Ask as text input | ||
| - "Are there any known concerns or blockers for this rebase?" | ||
|
|
||
| 3. **Special instructions for carry patches**: Ask as text input | ||
| - "Do you have any special instructions for existing carry patches or new carries to add?" | ||
|
|
||
| Then, explain the workflow upfront: | ||
| "I'll guide you through the rebase process with the following steps: | ||
| 1. **Analyze Current State** - Review current version, carries, and dependencies | ||
| 2. **Execute Rebase** - Cherry-pick carries, handle conflicts, squash commits, regenerate vendor | ||
| 3. **Generate Reports** - Create comprehensive rebase report and stakeholder review document | ||
| 4. **User Review** - Present summary and ask for your feedback before creating PR | ||
| 5. **Create PR** - After your approval, create PR with high-level summary | ||
|
|
||
| Before creating the PR, I'll present you with a summary and ask for any adjustments needed. You'll have a chance to review everything before the PR goes out." | ||
|
|
||
| ### 2. Analyze Current State | ||
|
|
||
| **Upstream Changes**: | ||
| - Review CoreDNS release notes at `https://github.com/coredns/coredns/releases/tag/v<version>` | ||
| - Analyze incoming changes, new features, bug fixes, deprecations | ||
| - Identify breaking changes, API migrations, dependency updates | ||
| - Assess compatibility impact on OpenShift-specific carries and plugins | ||
| - Note toolchain changes (Go version, build requirements) | ||
|
|
||
| **Downstream State**: | ||
| - Read `openshift-rebase/REBASE.md` for workflow | ||
| - Check current version and carries | ||
| - Review `openshift-rebase/carries/*.md` for carry reapply instructions | ||
| - Identify all carry commits since last rebase | ||
| - Read each carry commit's description to understand the changes and context | ||
| - Analyze carry audit (classify as: still needed / already upstream / obsoleted) | ||
|
|
||
| ### 3. Execute the Rebase | ||
|
|
||
| Follow the workflow documented in `openshift-rebase/REBASE.md`: | ||
| 1. Preparation and setup | ||
| 2. Cherry-pick carries (handle conflicts, skip obsolete commits) | ||
| 3. Cleanup commit history (squash related commits) | ||
| 4. Regenerate vendor commit | ||
| 5. Build and test validation | ||
|
|
||
| **IMPORTANT**: | ||
| - Record all git commands executed during the rebase for the report | ||
| - Document EVERY conflict, skip, and squash operation as they occur | ||
| - Document any explicit user feedback, guidance, or decisions provided during the rebase | ||
| - You will include all of this in Section 3: Execution Log of the final report | ||
|
|
||
| ### 4. Generate Complete Rebase Report | ||
|
|
||
| After executing the rebase, create `openshift-rebase/reports/rebase_to_v<version>.md` containing: | ||
|
|
||
| **Section 1: Overview** | ||
| - Current CoreDNS version | ||
| - Target rebase version | ||
| - Divergence metrics (commits ahead/behind) | ||
| - Merge helper commit strategy explanation | ||
|
|
||
| **Section 2: Carry Audit & Consolidation Plan** | ||
| Analyze all commits between last upstream tag and current main: | ||
|
|
||
| For each commit, classify as: | ||
| - **Still needed**: Must be forward-ported | ||
| - **Already upstream**: Can be dropped (note upstream commit) | ||
| - **Obsoleted**: No longer relevant | ||
|
|
||
| Include: | ||
| - Commits lacking `UPSTREAM: <carry>:` prefix that may be downstream-specific | ||
| - Consolidation recommendations (e.g., squash multiple ART commits, plugin version bumps) | ||
| - Proper commit message format with `UPSTREAM: <carry>: openshift:` prefix | ||
| - Order of carry application (vendor towards the end) | ||
|
|
||
| **Section 3: Execution Log** | ||
|
|
||
| Document what happened during the actual rebase execution: | ||
|
|
||
| **Conflicts Resolved**: | ||
| For each conflict encountered: | ||
| - Commit: <hash> - <subject> | ||
| - Type: [modify/delete | content | rename/delete | empty] | ||
| - Resolution: [resolved | skipped] | ||
| - Details: What conflicted, action taken, reasoning | ||
|
|
||
| **Skipped Commits**: | ||
| For each skipped commit: | ||
| - <hash> - <subject> | ||
| - Reason: Why it was skipped (already upstreamed, obsoleted, etc.) | ||
| - Details: Specific upstream commit or change that made this obsolete | ||
|
|
||
| **Squashed Commits**: | ||
| For each squash operation: | ||
| - Into: <target-commit-subject> | ||
| - Squashed: List of commits consolidated | ||
| - Reason: Why these were combined | ||
|
|
||
| **User Feedback**: | ||
| Document any explicit feedback, guidance, or decisions provided by the user during the rebase: | ||
| - Timestamp/context: When the feedback was given | ||
| - Feedback: Exact user input or decision | ||
| - Action taken: How the feedback was incorporated | ||
| - Rationale: Why this approach was chosen based on user guidance | ||
|
|
||
| **Section 4: Risk Assessment** | ||
| - Summary of upstream changes (brief overview from release notes) | ||
| - Breaking changes and their impact on carries | ||
| - Dependency updates and compatibility concerns (especially k8s deps for ocp_dnsnameresolver) | ||
| - Toolchain changes (Go version, build requirements) | ||
| - Testing hotspots (areas needing extra validation) | ||
| - Build/test results | ||
| - Link to stakeholder review document for detailed upstream analysis | ||
|
|
||
| ### 5. Generate Stakeholder Review Document | ||
|
|
||
| Create `openshift-rebase/reports/rebase_v<version>_stakeholder_review.md`: | ||
|
|
||
| **Purpose**: Concise (2-3 pages) meeting agenda for pre-merge review | ||
|
|
||
| **Structure**: | ||
|
|
||
| **Upstream Changes Analysis** (most important section): | ||
| - Link to CoreDNS release notes: https://github.com/coredns/coredns/releases/tag/v<version> | ||
| - New features and enhancements (what's new, why it matters for OpenShift) | ||
| - Bug fixes (especially ones affecting stability or security) | ||
| - Breaking changes and deprecations (migration required?) | ||
| - Dependency updates (k8s client libs, Go version, etc.) | ||
| - Risk assessment: High/Medium/Low for each category | ||
| - OpenShift compatibility impact (will carries still work? does ocp_dnsnameresolver need updates?) | ||
|
|
||
| **Downstream Changes**: | ||
| - High-risk commits requiring discussion | ||
| - Carry consolidation summary | ||
| - External plugin status (ocp_dnsnameresolver compatibility with new deps) | ||
| - Toolchain changes needed (Go version bumps, build config) | ||
|
|
||
| **Action Items**: | ||
| - Decisions needed before merge | ||
| - Testing requirements | ||
| - Owners assigned | ||
| - Space for meeting notes | ||
|
|
||
| **Guidelines**: | ||
| - Upstream changes section should be most detailed (1-2 paragraphs per major change) | ||
| - Focus on impact and risk, not implementation details | ||
| - Include links (GitHub releases, upstream issues, PRs) | ||
| - Non-technical stakeholders should understand risks | ||
| - Highlight anything that needs stakeholder decision or approval | ||
|
|
||
| ### 6. Commit Reports with DROP Prefix | ||
|
|
||
| After generating all reports, commit them with the `UPSTREAM: <drop>:` prefix: | ||
|
|
||
| ```bash | ||
| git add openshift-rebase/reports/ | ||
| git commit -m "UPSTREAM: <drop>: openshift: Add rebase v<version> reports and documentation" | ||
| ``` | ||
|
|
||
| **Rationale**: Using `<drop>:` ensures these version-specific reports are automatically skipped in the next rebase, preventing accumulation of outdated reports across multiple rebase cycles. | ||
|
|
||
| ### 7. User Review and Feedback | ||
|
|
||
| **IMPORTANT**: Before creating the PR, present a summary to the user and ask for review. | ||
|
|
||
| Provide a concise summary with: | ||
| - Version transition (v<old> → v<new>) | ||
| - Stats: X carries reapplied, Y dropped, Z squashed, N conflicts resolved | ||
| - Key highlights: Major dependency changes, toolchain updates, breaking changes, etc. | ||
| - Build/test status | ||
| - Location of detailed reports | ||
|
|
||
| Then ask: | ||
| - "Please review the rebase results. The detailed reports are in `openshift-rebase/reports/`. Do you have any feedback or adjustments needed before I create the PR?" | ||
| - Wait for user response | ||
| - **Document any user feedback** in the report's Section 3: Execution Log > User Feedback | ||
| - Make any requested changes to the rebase, reports, or commits | ||
| - Update the reports to reflect changes made based on feedback | ||
| - Only proceed to PR creation after user approval | ||
|
|
||
| ### 8. Create Pull Request | ||
|
|
||
| Create a PR with a concise, high-level description. This is a **bird's eye view** summary - keep it scannable and focused on key information only. | ||
|
|
||
| **PR Title**: `Rebase to CoreDNS v<version>` | ||
|
|
||
| **PR Description Structure**: | ||
|
|
||
| ````markdown | ||
| # Rebase to CoreDNS v<version> | ||
|
|
||
| ## Summary | ||
| - **Version**: v<old> → v<new> | ||
| - **Carries**: X reapplied, Y dropped, Z squashed | ||
| - **Conflicts**: N resolved | ||
| - **Validation**: ✅ Build and tests passing | ||
|
|
||
| ## Action Plan | ||

| go build && make test | ||
| ``` | ||
|
|
||
| ## Carries Applied (X) | ||
| - Brief list of carry commits (one-line descriptions) | ||
| - Group similar carries (e.g., "ART build configuration (squashed 3 commits)") | ||
| - Note regenerated vendor tree | ||
|
|
||
| ## Dropped (Y) | ||
| - List dropped commits with reason (already upstream #PR, obsoleted, etc.) | ||
|
|
||
| ## High Priority Review Items | ||
| - ⚠️ **Item 1**: Brief description (e.g., "Go 1.21: Toolchain bump - verify CI") | ||

| 📄 [Full Rebase Report](openshift-rebase/reports/rebase_to_v<version>.md) | 📋 [Stakeholder Review](openshift-rebase/reports/rebase_v<version>_stakeholder_review.md) | ||
| ```` | ||
|
|
||
| **Guidelines**: | ||
| - Keep descriptions concise (1 line per item) | ||
| - Focus on stats and high-level actions, not details | ||
| - Only flag high-priority concerns (breaking changes, major dependency updates, compatibility risks) | ||
| - Commands section should show actual commands run, with comments for major events | ||
| - Link to full reports at the bottom | ||
|
|
||
| **After PR Creation**: | ||
| Remind the user: "The stakeholder review document (`rebase_v<version>_stakeholder_review.md`) is intended for a peer review meeting. You can copy and paste it into a Google Doc as a starting point for discussion with your team." | ||
|
|
||
| ## Key References | ||
|
|
||
| - **Canonical workflow**: `openshift-rebase/REBASE.md` (human instructions) | ||
| - **Carry instructions**: `openshift-rebase/carries/*.md` (detailed reapply steps) | ||
|
|
||
| ## Report Storage | ||
|
|
||
| All reports go in `openshift-rebase/reports/`: | ||
| - `rebase_to_v<version>.md` - Complete rebase report (includes carry audit, execution log, and action plan) | ||
| - `rebase_v<version>_stakeholder_review.md` - Stakeholder meeting document | ||
|
|
||
| ## Critical Reminders | ||
|
|
||
| - Merge helper comes FIRST, carries on top | ||
| - All carry commits need `UPSTREAM: <carry>: openshift:` prefix (except reports - use `<drop>:`) | ||
| - **Reports directory uses `UPSTREAM: <drop>:` prefix** - dropped each rebase to avoid accumulation | ||
| - Document all conflicts, skips, and squashes as they occur (include in Execution Log section of report) | ||
| - Read carry instructions from `openshift-rebase/carries/*.md` for guidance | ||
| - Create PR with concise bird's eye view summary - link to full reports for details | ||
| - **Stakeholder Review Document**: Remind the user that `rebase_v<version>_stakeholder_review.md` is intended for a peer review meeting. They can copy and paste it into a Google Doc as a starting point for discussion. | ||
