From 9d0d29ef183a1c70df118ca1f64beb5334b30e55 Mon Sep 17 00:00:00 2001 From: Cal Corum Date: Fri, 28 Nov 2025 12:09:09 -0600 Subject: [PATCH] CLAUDE: Add Alembic migrations and database session injection MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Database Infrastructure: - Added Alembic migration system (alembic.ini, env.py) - Migration 001: Initial schema - Migration 004: Stat materialized views (enhanced) - Migration 005: Composite indexes for performance - operations.py: Session injection support for test isolation - session.py: Enhanced session management Application Updates: - main.py: Integration with new database infrastructure - health.py: Enhanced health checks with pool monitoring Integration Tests: - conftest.py: Session injection pattern for reliable tests - test_operations.py: Database operations tests - test_migrations.py: Migration verification tests Session injection pattern enables: - Production: Auto-commit per operation - Testing: Shared session with automatic rollback - Transactions: Multiple ops, single commit 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- backend/alembic.ini | 65 ++ backend/alembic/env.py | 101 +++ backend/alembic/script.py.mako | 26 + .../alembic/versions/001_initial_schema.py | 288 ++++++++ .../004_create_stat_materialized_views.py | 4 +- .../versions/005_add_composite_indexes.py | 80 ++ backend/app/api/routes/health.py | 156 ++++ backend/app/database/operations.py | 688 ++++++++---------- backend/app/database/session.py | 16 +- backend/app/main.py | 285 +++++++- backend/tests/integration/conftest.py | 160 +++- .../integration/database/test_migrations.py | 269 +++++++ .../integration/database/test_operations.py | 608 ++++++++-------- 13 files changed, 2020 insertions(+), 726 deletions(-) create mode 100644 backend/alembic.ini create mode 100644 backend/alembic/env.py create mode 100644 backend/alembic/script.py.mako create mode 100644 backend/alembic/versions/001_initial_schema.py create mode 100644 backend/alembic/versions/005_add_composite_indexes.py create mode 100644 backend/tests/integration/database/test_migrations.py diff --git a/backend/alembic.ini b/backend/alembic.ini new file mode 100644 index 0000000..c9db211 --- /dev/null +++ b/backend/alembic.ini @@ -0,0 +1,65 @@ +# Alembic configuration file for Paper Dynasty Game Engine + +[alembic] +# Path to migration scripts +script_location = alembic + +# Template used to generate migration files +file_template = %%(rev)s_%%(slug)s + +# Output encoding +output_encoding = utf-8 + +# Truncate database identifiers to this length +truncate_slug_length = 40 + +# Revision IDs to use for new migrations (default is 12 char hex) +revision_environment = false + +# sourceless mode - ignore .pyc files +sourceless = false + +# version path separator (OS agnostic) +version_path_separator = os + +[post_write_hooks] +# Optional Ruff formatting after generating migrations +# hooks = ruff +# ruff.type = console_scripts +# ruff.entrypoint = ruff +# ruff.options = format REVISION_SCRIPT_FILENAME + +# Logging configuration +[loggers] +keys = root,sqlalchemy,alembic + +[handlers] +keys = console + +[formatters] +keys = generic + +[logger_root] +level = WARN +handlers = console +qualname = + +[logger_sqlalchemy] +level = WARN +handlers = +qualname = sqlalchemy.engine + +[logger_alembic] +level = INFO +handlers = +qualname = alembic + +[handler_console] +class = StreamHandler +args = (sys.stderr,) +level = NOTSET +formatter = generic + +[formatter_generic] +format = %(levelname)-5.5s [%(name)s] %(message)s +datefmt = %H:%M:%S diff --git a/backend/alembic/env.py b/backend/alembic/env.py new file mode 100644 index 0000000..224aa18 --- /dev/null +++ b/backend/alembic/env.py @@ -0,0 +1,101 @@ +""" +Alembic migration environment configuration. + +Uses synchronous psycopg2 driver for migrations while the application +uses asyncpg at runtime.
