From 0dc39bb43b64940dbae7daee12a7839218955d21 Mon Sep 17 00:00:00 2001 From: Greg Burd Date: Tue, 10 Mar 2026 10:30:05 -0400 Subject: [PATCH 01/11] Rebase on upstream hourly, add AI/LLM PR review MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Hourly upstream sync from postgres/postgres (24x daily) - AI-powered PR reviews using AWS Bedrock Claude Sonnet 4.5 - Multi-platform CI via existing Cirrus CI configuration - Cost tracking and comprehensive documentation Features: - Automatic issue creation on sync conflicts - PostgreSQL-specific code review prompts (C, SQL, docs, build) - Cost limits: $15/PR, $200/month - Inline PR comments with security/performance labels - Skip draft PRs to save costs Documentation: - .github/SETUP_SUMMARY.md - Quick setup overview - .github/QUICKSTART.md - 15-minute setup guide - .github/PRE_COMMIT_CHECKLIST.md - Verification checklist - .github/docs/ - Detailed guides for sync, AI review, Bedrock See .github/README.md for complete overview Complete Phase 3: Windows builds + fix sync for CI/CD commits Phase 3: Windows Dependency Build System - Implement full build workflow (OpenSSL, zlib, libxml2) - Smart caching by version hash (80% cost reduction) - Dependency bundling with manifest generation - Weekly auto-refresh + manual triggers - PowerShell download helper script - Comprehensive usage documentation Sync Workflow Fix: - Allow .github/ commits (CI/CD config) on master - Detect and reject code commits outside .github/ - Merge upstream while preserving .github/ changes - Create issues only for actual pristine violations Documentation: - Complete Windows build usage guide - Update all status docs to 100% complete - Phase 3 completion summary All three CI/CD phases complete (100%): ✅ Hourly upstream sync with .github/ preservation ✅ AI-powered PR reviews via Bedrock Claude 4.5 ✅ Windows dependency builds with smart caching Cost: $40-60/month total See .github/PHASE3_COMPLETE.md for details Fix sync to allow 'dev setup' commits on master The sync workflow was failing because the 'dev setup v19' commit modifies files outside .github/. Updated workflows to recognize commits with messages starting with 'dev setup' as allowed on master. Changes: - Detect 'dev setup' commits by message pattern (case-insensitive) - Allow merge if commits are .github/ OR dev setup OR both - Update merge messages to reflect preserved changes - Document pristine master policy with examples This allows personal development environment commits (IDE configs, debugging tools, shell aliases, Nix configs, etc.) on master without violating the pristine mirror policy. Future dev environment updates should start with 'dev setup' in the commit message to be automatically recognized and preserved. See .github/docs/pristine-master-policy.md for complete policy See .github/DEV_SETUP_FIX.md for fix summary Optimize CI/CD costs by skipping builds for pristine commits Add cost optimization to Windows dependency builds to avoid expensive builds when only pristine commits are pushed (dev setup commits or .github/ configuration changes). Changes: - Add check-changes job to detect pristine-only pushes - Skip Windows builds when all commits are dev setup or .github/ only - Add comprehensive cost optimization documentation - Update README with cost savings (~40% reduction) Expected savings: ~$3-5/month on Windows builds, ~$40-47/month total through combined optimizations. Manual dispatch and scheduled builds always run regardless. --- .github/.gitignore | 18 + .github/DEV_SETUP_FIX.md | 163 ++ .github/IMPLEMENTATION_STATUS.md | 368 +++ .github/PHASE3_COMPLETE.md | 284 +++ .github/PRE_COMMIT_CHECKLIST.md | 393 +++ .github/QUICKSTART.md | 378 +++ .github/README.md | 315 +++ .github/SETUP_SUMMARY.md | 369 +++ .github/docs/ai-review-guide.md | 512 ++++ .github/docs/bedrock-setup.md | 298 +++ .github/docs/cost-optimization.md | 219 ++ .github/docs/pristine-master-policy.md | 225 ++ .github/docs/sync-setup.md | 326 +++ .github/docs/windows-builds-usage.md | 254 ++ .github/docs/windows-builds.md | 435 ++++ .github/scripts/ai-review/config.json | 123 + .github/scripts/ai-review/package-lock.json | 2192 +++++++++++++++++ .github/scripts/ai-review/package.json | 34 + .../scripts/ai-review/prompts/build-system.md | 197 ++ .github/scripts/ai-review/prompts/c-code.md | 190 ++ .../ai-review/prompts/documentation.md | 134 + .github/scripts/ai-review/prompts/sql.md | 156 ++ .github/scripts/ai-review/review-pr.js | 604 +++++ .github/scripts/windows/download-deps.ps1 | 113 + .github/windows/manifest.json | 154 ++ .github/workflows/ai-code-review.yml | 69 + .github/workflows/sync-upstream-manual.yml | 249 ++ .github/workflows/sync-upstream.yml | 256 ++ .github/workflows/windows-dependencies.yml | 597 +++++ 29 files changed, 9625 insertions(+) create mode 100644 .github/.gitignore create mode 100644 .github/DEV_SETUP_FIX.md create mode 100644 .github/IMPLEMENTATION_STATUS.md create mode 100644 .github/PHASE3_COMPLETE.md create mode 100644 .github/PRE_COMMIT_CHECKLIST.md create mode 100644 .github/QUICKSTART.md create mode 100644 .github/README.md create mode 100644 .github/SETUP_SUMMARY.md create mode 100644 .github/docs/ai-review-guide.md create mode 100644 .github/docs/bedrock-setup.md create mode 100644 .github/docs/cost-optimization.md create mode 100644 .github/docs/pristine-master-policy.md create mode 100644 .github/docs/sync-setup.md create mode 100644 .github/docs/windows-builds-usage.md create mode 100644 .github/docs/windows-builds.md create mode 100644 .github/scripts/ai-review/config.json create mode 100644 .github/scripts/ai-review/package-lock.json create mode 100644 .github/scripts/ai-review/package.json create mode 100644 .github/scripts/ai-review/prompts/build-system.md create mode 100644 .github/scripts/ai-review/prompts/c-code.md create mode 100644 .github/scripts/ai-review/prompts/documentation.md create mode 100644 .github/scripts/ai-review/prompts/sql.md create mode 100644 .github/scripts/ai-review/review-pr.js create mode 100644 .github/scripts/windows/download-deps.ps1 create mode 100644 .github/windows/manifest.json create mode 100644 .github/workflows/ai-code-review.yml create mode 100644 .github/workflows/sync-upstream-manual.yml create mode 100644 .github/workflows/sync-upstream.yml create mode 100644 .github/workflows/windows-dependencies.yml diff --git a/.github/.gitignore b/.github/.gitignore new file mode 100644 index 0000000000000..a447f99442861 --- /dev/null +++ b/.github/.gitignore @@ -0,0 +1,18 @@ +# Node modules +scripts/ai-review/node_modules/ +# Note: package-lock.json should be committed for reproducible CI/CD builds + +# Logs +scripts/ai-review/cost-log-*.json +scripts/ai-review/*.log + +# OS files +.DS_Store +Thumbs.db + +# Editor files +*.swp +*.swo +*~ +.vscode/ +.idea/ diff --git a/.github/DEV_SETUP_FIX.md b/.github/DEV_SETUP_FIX.md new file mode 100644 index 0000000000000..2f628cc61a777 --- /dev/null +++ b/.github/DEV_SETUP_FIX.md @@ -0,0 +1,163 @@ +# Dev Setup Commit Fix - Summary + +**Date:** 2026-03-10 +**Issue:** Sync workflow was failing because "dev setup" commits were detected as pristine master violations + +## Problem + +The sync workflow was rejecting the "dev setup v19" commit (e5aa2da496c) because it modifies files outside `.github/`.

Adds new TsrRoutine structure with function pointers for toast operations, enabling extensible TOAST mechanics beyond the traditional heap-based implementation.

Insert, update and fetch. heap_toast_insert_or_update method contains +Heap AM TOAST data storage strategies, deciding if TOAST will be used to store +external and extended data according to overall Tuple size. +Strategies explanation (from comments): +>>> + Compress and/or save external until data fits into target length + + 1: Inline compress attributes with attstorage EXTENDED, and store very + large attributes with attstorage EXTENDED or EXTERNAL external + immediately + 2: Store attributes with attstorage EXTENDED or EXTERNAL external + 3: Inline compress attributes with attstorage MAIN + 4: Store attributes with attstorage MAIN external + + Look for attributes with attstorage EXTENDED to compress.

But skip this if there's no + toast table to push them to. + + Round 3 - this time we take attributes with storage MAIN into + compression + + Finally we store attributes of type MAIN externally.
