From 60d922204880131aa1fa3d9b38e4e9a243a81e59 Mon Sep 17 00:00:00 2001 From: Cody Fincher Date: Sat, 11 Oct 2025 20:20:40 +0000 Subject: [PATCH 01/37] feat: implement timestamp-based migration versioning (#116) Implement timestamp-based migration versioning to eliminate PR conflicts when multiple developers create migrations concurrently. Uses format YYYYMMDDHHmmss_description.sql instead of sequential 0001, 0002. Breaking Changes: - Migration file format changed from sequential (0001) to timestamp - Existing migrations must be recreated with new timestamp format - Database schema adds version_type and execution_sequence columns - No automated migration path (clean break for pre-1.0) Features Added: - Timestamp-based version generation (UTC timezone) - Out-of-order migration detection with configurable strict mode - Mixed format support (sequential + timestamp during transition) - Version-aware sorting and comparison - Enhanced migration tracking with execution sequence Implementation: - Created sqlspec.utils.version module for version parsing/comparison - Created sqlspec.migrations.validation module for out-of-order detection - Updated migration commands to generate timestamp versions - Enhanced database schema with version_type and execution_sequence - Added comprehensive test coverage (32 new tests, 152 total passing) Configuration: - strict_ordering: False (default) - warn on out-of-order migrations - allow_missing parameter in upgrade() for per-command override Files Changed: - sqlspec/utils/version.py (NEW) - Version parsing system - sqlspec/migrations/validation.py (NEW) - Out-of-order detection - sqlspec/exceptions.py - Added migration exceptions - sqlspec/migrations/base.py - Schema and sorting updates - sqlspec/migrations/tracker.py - Record new columns - sqlspec/migrations/commands.py - Timestamp generation and validation - tests/unit/test_migrations/test_version.py (NEW) - 17 tests - tests/unit/test_migrations/test_validation.py (NEW) -

feat(migrations): add auto-sync for version reconciliation Implements automatic version reconciliation in upgrade command to improve developer workflow when pulling renamed migrations from teammates. Key changes: - Added _synchronize_version_records() to sync/async commands - Auto-detects renamed migrations and updates DB tracking - Validates checksums before updating - Added --no-auto-sync CLI flag - Added migration_config.auto_sync config option - Defaults to enabled for best UX Developers can now just run migrate after pulling changes without manually running fix command.

resolve hybrid versioning CI failures Fixes all 11 test failures from GitHub Actions CI run #18610119292: **Oracle Schema Migration (2 tests)** - Fixed data_dictionary.get_columns() to use modern result.get_data() API instead of deprecated result.data attribute - Updated docstrings to reflect UPPERCASE column names (COLUMN_NAME, etc.) - Updated migrations.py to use COLUMN_NAME (uppercase) when querying columns **Extension Migration Validation (2 tests)** - Enhanced _extract_version() in loaders.py and runner.py to handle extension-prefixed filenames (ext_litestar_0001_init.sql) - Added support for ext__ format extraction **Downgrade SQL Syntax Errors (5 tests)** - Fixed table name extraction in test files - Changed from split("_", 2)[1] to split("_", 2)[2].rsplit(".", 1)[0] - Correctly extracts "orders" from "0003_create_orders.sql" instead of "create" **Auto-sync Reconciliation (2 tests)** - Added checksum-based fallback in _synchronize_version_records() - When conversion_map is empty (after files renamed), matches by checksum - Extracted try/except out of loop into helper methods to avoid PERF203 **Version Ordering** - Updated get_migration_files() to use parse_version() for sorting - Ensures Sequential < Timestamp version ordering rule is respected - Prevents "9999" sorting after timestamps alphabetically All tests passing (20/20).
