A single mapping is shared across all rows in a result set, and values are accessed via index. +3. **GIL Minimization**: Data is decoded into optimized Rust structures before being converted to Python objects at the very last moment, minimizing the time the GIL is held. + ### Data Flow (Query Execution) ``` -Python: Post.objects.filter(active=True).order_by("-views").limit(10) - │ - ▼ -QuerySet.filter() → builder.add_filter("active", "exact", True, negated=False) - │ - ▼ -QuerySet.order_by() → builder.add_order_by("-views") +Python: Post.objects.filter(active=True).limit(10) │ ▼ -await queryset → QuerySet._execute() +QuerySet → PyQueryBuilder (ryx-python) │ ▼ -PyQueryBuilder.fetch_all() (Rust side) +compiler::compile (ryx-query) → CompiledQuery { sql, values } │ ▼ -compiler::compile(&QueryNode) → CompiledQuery { sql, values } - │ SELECT * FROM "posts" WHERE "active" = ? - │ ORDER BY "views" DESC LIMIT 10 - ▼ -executor::fetch_all(compiled) → sqlx::query(sql).bind(values).fetch_all(pool) +executor::fetch_all (ryx-backend) → sqlx::query(sql).fetch_all(pool) │ ▼ -decode_row(AnyRow) → HashMap +decode_rows (ryx-backend) → Vec (Zero-allocation) │ ▼ -json_to_py() → PyDict +RowView → PyDict (ryx-python) │ ▼ -Model._from_row(row) → Model instances +Model._from_row(row) → Model instances ``` -### Key Architectural Decisions - -1. **Immutable builder pattern** — Every `QuerySet` method returns a **new** QuerySet (never mutates self). The Rust `QueryNode` builder methods use `#[must_use]` and `self` (not `&mut self`) for the same immutability guarantee. - -2. **AnyPool over typed pools** — Uses `sqlx::any::AnyPool` for a single code path across Postgres/MySQL/SQLite. Loses compile-time query checking but gains runtime flexibility. - -3. **GIL minimization** — Rust executor decodes rows to `HashMap` first, then converts to `PyDict` only at the PyO3 boundary. This avoids holding the GIL during SQL execution. - -4. **ContextVar transaction propagation** — Active transactions are stored in `contextvars.ContextVar` so they propagate through async call stacks without explicit passing. - -5. **Two-tier lookup registry** — Built-in lookups are static `fn` pointers (fast, thread-safe). Custom lookups store pre-rendered SQL templates with `{col}` placeholders. Custom lookups can override built-ins (checked first). - -6. **Deferred reverse FK resolution** — ForeignKey fields with string forward references accumulate in `_pending_reverse_fk` and are resolved after each model class is defined by the metaclass. -

This is achieved by eliminating common abstractions that introduce runtime overhead. + +## 1. Enum Dispatch vs. Dynamic Dispatch + +In traditional Rust database wrappers, backend-specific logic is often handled via traits and `dyn` objects (dynamic dispatch). While flexible, this introduces **vtable lookups**, which prevent the compiler from inlining functions and add several nanoseconds to every call. + +Ryx replaces `dyn` traits with **Enum Dispatch**. + +### The Old Way (`dyn`) +```rust +trait Connection { + fn execute(&self, sql: &str) -> Result<...>; +} + +struct RyxConnection { + inner: Box, // Vtable lookup on every call +} +``` + +### The Ryx Way (Enums) +```rust +pub enum RyxConnection { + Postgres(PgPool), + MySql(MySqlPool), + Sqlite(SqlitePool), +} + +impl RyxConnection { + pub fn execute(&self, sql: &str) -> Result<...> { + match self { + Self::Postgres(p) => p.execute(sql), // Compiler can inline this! + Self::MySql(m) => m.execute(sql), + Self::Sqlite(s) => s.execute(sql), + } + } +} +``` +By using enums, we move the dispatch decision to a simple branch that the CPU can predict perfectly, enabling the LLVM compiler to perform aggressive inlining and optimization. + +## 2. Zero-Allocation Row Decoding + +The most significant bottleneck in any ORM is transforming database rows into language-level objects. Most ORMs create a `HashMap` or a similar dictionary for every single row, leading to thousands of small allocations per query. + +Ryx implements a **Zero-Allocation Row System** using `RowView` and `RowMapping`. + +### The Strategy +Instead of duplicating column names for every row, Ryx separates the **Structure** (mapping) from the **Data** (view). + +- **`RowMapping`**: Created once per query. It contains the column names and their indices in the result set. +- **`RowView`**: Created for each row. It contains only the raw data pointers/values and a reference to the shared `RowMapping`. + +### Performance Impact +| Approach | Allocations per Row | Memory Layout | Complexity | +|---|---|---|---| +| `HashMap` | $\sim$10-20 | Scattered | $O(\text{cols})$ | +| **RowView** | **1 (The View itself)** | Linear / Contiguous | $O(1)$ | + +This reduces allocator pressure by orders of magnitude and significantly improves cache locality. + +## 3. GIL Minimization + +The Python Global Interpreter Lock (GIL) is the enemy of concurrency. Ryx ensures that the GIL is held for the absolute minimum amount of time. + +1. **Execution**: SQL is executed and results are fetched in Rust using `tokio` and `sqlx` without any Python objects involved. +2. **Decoding**: Rows are decoded into `RowView` structures (pure Rust). +3. **Bridging**: Only when the results are returned to Python are the `RowView` entries converted into `PyDict` objects. + +This means if a query takes 100ms to execute on the database, the GIL is **not held** for those 100ms, allowing other Python threads to continue running. + +## 4. PyO3 Bound Objects + +Ryx utilizes the latest PyO3 `Bound<'py, T>` API. By avoiding `Py` (which uses reference counting) and using `Bound` (which uses direct pointers), we reduce the overhead of interacting with Python objects and eliminate unnecessary `inc_ref`/`dec_ref` calls. diff --git a/docs/doc/internals/rust-core.mdx b/docs/doc/internals/rust-core.mdx index 80f255f..1dce932 100644 --- a/docs/doc/internals/rust-core.mdx +++ b/docs/doc/internals/rust-core.mdx @@ -7,104 +7,61 @@ sidebar_position: 3 The compiled engine that powers Ryx.

-2. **Python Dependencies**: Install test dependencies: - ```bash - pip install pytest pytest-asyncio - ``` - -## Running Tests - -### All Tests -```bash -pytest -``` - -### Unit Tests Only (Fast, no

-``` - -### Specific Test -```bash -pytest tests/integration/test_crud.py::TestCreate::test_create_simple -``` - -### With Coverage -```bash -pytest --cov=ryx --cov-report=html -``` - -## Test Configuration - -- **Database**: Tests use SQLite in-memory database (`sqlite://:memory:`) -- **Isolation**: Each test function gets a clean database state -- **Async**: All tests are async and use `pytest-asyncio` -- **Fixtures**: Shared test data via `conftest.py` - -## Test Models - -The test suite uses these models defined in `conftest.py`: - -- **Author**: Basic model with CharField, EmailField, BooleanField, TextField -- **Post**: Complex model with ForeignKey, unique constraints, indexes, custom validation -- **Tag**: Simple model with unique CharField - -## Key Test Areas - -### Unit Tests -- Model metaclass and field contribution -- Field validation and type conversion -- Validator logic -- QuerySet building and Q object operations -- Exception hierarchy - -### Integration Tests -- CRUD operations (create, get, update, delete) -- Complex queries with filters, ordering, pagination -- Q object combinations -- Bulk operations (create, update, delete, stream) -- Transaction management and isolation -- Foreign key relationships -- Model validation and constraints - -## Writing New Tests - -### Unit Tests -Use mock for `ryx_core` to test Python logic in isolation: - -```python -import sys -mock_core = types.ModuleType("ryx.ryx_core") -sys.modules["ryx.ryx_core"] = mock_core -``` - -### Integration Tests -Use fixtures from `conftest.py` for database setup and sample data: - -```python -@pytest.mark.asyncio -async def test_something(clean_tables, sample_author): - # Test logic here - pass -``` - -### Async Tests -All database tests must be async and marked with `@pytest.mark.asyncio`. - -## Troubleshooting - -### Import Errors -Make sure the Rust extension is compiled: -```bash -maturin develop -``` - -### Database Errors -Tests expect SQLite. Check that the database URL in `conftest.py` is correct. - -### Test Failures -- Check test isolation (each test should clean up after itself) -- Verify fixture dependencies -- Check async/await usage - -## Coverage Goals - -- **Models**: 95%+ coverage of model creation, field handling, validation -- **QuerySet**: 90%+ coverage of query building, filtering, ordering -- **Fields**: 95%+ coverage of all field types and validation -- **Integration**: 85%+ coverage of real database operations \ No newline at end of file diff --git a/tests/conftest.py b/tests/conftest.py deleted file mode 100644 index b55000c..0000000 --- a/tests/conftest.py +++ /dev/null @@ -1,552 +0,0 @@ -""" -Pytest configuration and shared fixtures for Ryx ORM tests. -""" -
