Lazy Imports + +## Overview + +This design replaces the eager submodule import block at the end of each generated `__init__.py` with a PEP 562 lazy loading mechanism using module-level `__getattr__` and `__dir__`. The change is scoped to the `PythonModule.emit()` method in `packages/jsii-pacmak/lib/targets/python.ts`. + +Currently, every non-assembly-loading `__init__.py` ends with: + +```python +# Loading modules to ensure their types are registered with the jsii runtime library +from . import submodule_a +from . import submodule_b +``` + +This eagerly loads every submodule at import time. For `aws-cdk-lib`, this means thousands of modules are loaded when a user writes `import aws_cdk`, even if they only need `aws_cdk.aws_s3`. + +The new pattern replaces this with: + +```python +import importlib as _importlib + +_SUBMODULES = { + "submodule_a", + "submodule_b", +} + +def __getattr__(name: str) -> object: + if name in _SUBMODULES: + mod = _importlib.import_module(f".{name}", __name__) + globals()[name] = mod + return mod + raise AttributeError(f"module {__name__!r} has no attribute {name!r}") + +def __dir__() -> list[str]: + return [*__all__, *_SUBMODULES] +``` + +Submodules are only imported when first accessed (e.g., `aws_cdk.aws_s3`), at which point the jsii runtime type registration side effects fire as usual. Assembly-loading modules (`loadAssembly=true`) are excluded and continue to use eager imports. + +## Architecture + +The change is entirely within the code generation layer — no runtime changes are needed. The jsii Python runtime already supports on-demand type registration because types self-register when their containing module is imported. + +```mermaid +graph TD + A[PythonModule.emit] --> B{loadAssembly?} + B -->|Yes| C[Emit eager dependency imports
unchanged] + B -->|No| D{Has child submodules?} + D -->|No| E[Emit module as-is
no lazy loading code] + D -->|Yes| F[Emit _SUBMODULES set
__getattr__ / __dir__] + F --> G[Submodule names in __all__
publication.publish] + G --> H[Protocol stripper / intersection types] +``` + +### Key Design Decisions + +1. **`importlib.import_module` with relative path**: We use `importlib.import_module(f".{name}", __name__)` rather than `__import__` because it mirrors the semantics of `from . import ` and works correctly with `pkgutil.extend_path` namespace packages in both pip and bazel environments. + +2. **`globals()` caching**: After a successful import, the module is stored in `globals()` so that Python's normal attribute lookup finds it on subsequent accesses without re-entering `__getattr__`. This is the standard PEP 562 caching pattern. + +3. **Assembly-loading modules excluded**: Modules with `loadAssembly=true` (the `_jsii` package) must eagerly import dependencies to initialize the jsii kernel. These are already guarded by an `assert` in `addPythonModule` and never have child submodules registered. + +4. **`import importlib` added to module header**: We add `import importlib as _importlib` to the standard imports block (only when the module has submodules). The underscore-prefixed alias avoids polluting the module namespace and is hidden by `publication.publish()`. + +5. **Submodule names remain in `__all__`**: This preserves `from aws_cdk import *` behavior. When Python processes `import *`, it accesses each name in `__all__`, which triggers `__getattr__` for submodule names, lazily loading them. + +## Components and Interfaces + +### Modified Component: `PythonModule.emit()` method + +**File**: `packages/jsii-pacmak/lib/targets/python.ts` + +The `emit()` method is the only method that changes. The modification replaces the final "Loading modules" block with the lazy loading code block. + +#### Current flow (end of `emit()`): +1. Emit `__all__` list +2. Call `publication.publish()` +3. Emit eager `from . import ` for each child module +4. Emit protocol stripper / intersection types + +#### New flow (end of `emit()`): +1. Emit `__all__` list (unchanged — submodule names still included) +2. Call `publication.publish()` (unchanged) +3. **If modules.length > 0**: Emit `_SUBMODULES` set, `__getattr__`, and `__dir__` +4. Emit protocol stripper / intersection types (unchanged) + +#### New import in module header + +When `this.modules.length > 0`, add to the imports block: + +```typescript +code.line('import importlib as _importlib'); +``` + +This is placed alongside the existing standard library imports (`abc`, `builtins`, `datetime`, etc.). + +#### Generated lazy loading block + +```python +_SUBMODULES = { + "submodule_a", + "submodule_b", +} + +def __getattr__(name: str) -> object: + if name in _SUBMODULES: + mod = _importlib.import_module(f".{name}", __name__) + globals()[name] = mod + return mod + raise AttributeError(f"module {__name__!r} has no attribute {name!r}") + +def __dir__() -> list[str]: + return [*__all__, *_SUBMODULES] +``` + +### Unchanged Components + +- **`PythonModule.addPythonModule()`**: No changes. Submodule registration logic is unaffected. +- **`PythonModule.emitDependencyImports()`**: No changes.

WHEN a PythonModule has one or more child Submodules, THE Code_Generator SHALL emit a `_SUBMODULES` set literal containing the short names of all direct child Submodules instead of eager `from . import ` statements. +2. WHEN a PythonModule has one or more child Submodules, THE Code_Generator SHALL emit a module-level `__getattr__` function that imports the requested Submodule via `importlib.import_module` when the attribute name is found in `_SUBMODULES`. +3. WHEN `__getattr__` successfully imports a Submodule, THE Lazy_Loader SHALL cache the imported module in `globals()` so that subsequent accesses do not repeat the import. +4. WHEN `__getattr__` receives a name not in `_SUBMODULES`, THE Lazy_Loader SHALL raise an `AttributeError` with a message identifying the module and the missing attribute name. +5. WHEN a PythonModule has zero child Submodules, THE Code_Generator SHALL NOT emit the `_SUBMODULES` set, `__getattr__`, or `__dir__` functions. + +### Requirement 2: Preserve Module Introspection and Discoverability + +**User Story:** As a Python developer, I want `dir()`, tab-completion, and `from aws_cdk import *` to continue listing all submodules and public names, so that IDE tooling and interactive exploration remain functional. + +#### Acceptance Criteria + +1. WHEN a PythonModule has child Submodules, THE Code_Generator SHALL emit a module-level `__dir__` function that returns the union of `__all__` and the contents of `_SUBMODULES`. +2. THE Code_Generator SHALL continue to include Submodule short names in the `__all__` list so that `from import *` triggers lazy loading of all Submodules. +3. THE Code_Generator SHALL continue to call `publication.publish()` after defining `__all__` so that non-public names remain hidden from `dir()` output. + +### Requirement 3: Ensure jsii Type Registration on Demand + +**User Story:** As a CDK library author, I want jsii types to be registered with the jsii_Runtime when their containing module is first accessed, so that type marshaling and cross-language callbacks work correctly without eager loading. + +#### Acceptance Criteria + +1. WHEN a Submodule is lazily imported via `__getattr__`, THE Lazy_Loader SHALL trigger the same Type_Registration side effects that occur during an eager import of that Submodule. +2. WHEN the jsii_Runtime needs to deserialize a type from a Submodule that has not yet been lazily imported, THE jsii_Runtime SHALL be able to resolve the type by triggering the import of the containing Submodule. +3. IF a Type_Registration fails during lazy import, THEN THE Lazy_Loader SHALL propagate the original exception without suppressing it. + +### Requirement 4: Maintain Backwards Compatibility + +**User Story:** As an existing CDK Python user, I want my current code to continue working without modification after upgrading to a version with lazy imports, so that I do not experience regressions. + +#### Acceptance Criteria + +1. THE Code_Generator SHALL produce modules where `from aws_cdk import aws_s3` continues to work and returns the same module object as `import aws_cdk; aws_cdk.aws_s3`. +2. THE Code_Generator SHALL produce modules where `import aws_cdk.aws_s3` continues to work and populates `aws_cdk.aws_s3` as an attribute of the `aws_cdk` module. +3. THE Code_Generator SHALL produce modules where `from aws_cdk import *` loads all Submodules and makes them available in the caller's namespace. +4. WHEN a user accesses a Submodule attribute (e.g., `aws_cdk.aws_s3.Bucket`), THE Lazy_Loader SHALL return the same object that would have been returned under eager loading. +5. THE Code_Generator SHALL produce modules that are compatible with Python 3.8 and later versions. + +### Requirement 5: Support IDE and Type Checker Compatibility + +**User Story:** As a Python developer using mypy or pyright, I want type checking and autocomplete to work correctly with lazily loaded modules, so that my development experience is not degraded. + +#### Acceptance Criteria + +1. THE Code_Generator SHALL emit `__getattr__` and `__dir__` functions with type annotations that conform to PEP_562 so that type checkers recognize the module as supporting dynamic attribute access. +2. THE Code_Generator SHALL continue to emit type stub information (via `__all__` and existing type annotations) so that static analysis tools can resolve Submodule names. + +### Requirement 6: Preserve Assembly-Loading Module Behavior + +**User Story:** As a jsii-pacmak maintainer, I want the root assembly-loading module (the `_jsii` package loader) to remain unchanged, so that jsii assembly initialization is not affected by lazy loading. + +#### Acceptance Criteria + +1. WHEN a PythonModule has `loadAssembly` set to true, THE Code_Generator SHALL NOT apply lazy loading to that module and SHALL continue to emit eager dependency imports. +2. WHEN a PythonModule does not load an assembly, THE Code_Generator SHALL apply lazy loading to its child Submodule imports while preserving the eager `from ..._jsii import *` statement that loads the jsii assembly bindings. + +### Requirement 7: Generate Correct Relative Imports in Lazy Loader + +**User Story:** As a jsii-pacmak maintainer, I want the lazy loader to use relative imports consistent with the existing code generation strategy, so that the generated packages work in both pip-installed and bazel-managed environments. + +#### Acceptance Criteria + +1. THE Lazy_Loader SHALL use `importlib.import_module` with a relative import path (e.g., `f".{name}"`) and the current module's `__name__` as the package anchor. +2. THE Lazy_Loader SHALL produce import behavior equivalent to the current `from . import ` pattern so that `pkgutil.extend_path` namespace package resolution continues to function. + +### Requirement 8: Round-Trip Consistency of Generated Code + +**User Story:** As a jsii-pacmak maintainer, I want the generated Python code to be deterministic and reviewable, so that code generation changes can be validated in snapshot tests. + +#### Acceptance Criteria + +1. THE Code_Generator SHALL emit the `_SUBMODULES` set with Submodule names in sorted order so that generated code is deterministic across runs. +2. FOR ALL jsii assemblies, generating Python code and then re-generating from the same assembly SHALL produce identical output (round-trip determinism). +3. THE Code_Generator SHALL emit the lazy loading code block in a consistent location within `__init__.py`, replacing the current eager import block at the end of the file. diff --git a/.kiro/specs/python-lazy-imports/tasks.md b/.kiro/specs/python-lazy-imports/tasks.md new file mode 100644 index 0000000000..44403e8444 --- /dev/null +++ b/.kiro/specs/python-lazy-imports/tasks.md @@ -0,0 +1,96 @@ +# Implementation Plan: Python Lazy Imports + +## Overview + +Replace eager submodule imports in jsii-pacmak's Python code generator with PEP 562 lazy loading.

In Python, underscore-prefixed names are a convention meaning "private / internal." The `publication.publish()` call later in the file hides all names NOT in `__all__` from `dir()` and tab-completion. Since `_importlib` starts with an underscore and isn't in `__all__`, it becomes invisible to users. + +Without the underscore, users doing `dir(aws_cdk)` would see `importlib` listed as if it were part of the CDK API. That would be confusing. + +### Why we need it at all + +We need `importlib.import_module()` to do the actual lazy import inside `__getattr__`. We can't use a regular `import` statement inside `__getattr__` because we need to do a **relative** import with a **dynamic** name (the name comes from the function parameter). The `import` statement requires the module name to be hardcoded at write time. + +### Comparison to the old approach + +In the old code, there was no `import importlib` because the imports were done with regular `from . import aws_s3` statements — no dynamic importing needed. + +--- + +## Lines 3-7: `_SUBMODULES = {"aws_s3", "aws_lambda", "aws_ec2"}` + +### What this is + +A Python **set literal** containing strings.

With a set, this check is instant. With a list, Python would scan through all 300 items one by one. + +### Why underscore prefix + +Same reason as `_importlib` — it's an internal implementation detail, not part of the public API. Hidden by `publication.publish()`. + +### What this replaces + +Previously, there was no `_SUBMODULES` set. The submodule names only existed as part of the `from . import aws_s3` statements. Those statements both declared the names AND loaded the modules. Now we separate the two concerns: `_SUBMODULES` declares the names, and `__getattr__` loads them on demand. + +### Why this is fast + +Creating a set of 300 strings takes microseconds. No files are opened, no modules are loaded, no classes are defined.

If `__getattr__` raises `AttributeError`, Python raises `AttributeError` to the caller + +### Why this is the key to lazy loading + +When the file first executes, `aws_s3` is NOT in the module's namespace (because we didn't import it). So when someone writes `aws_cdk.aws_s3`, Python doesn't find `aws_s3` in step 1, and calls `__getattr__("aws_s3")` in step 2. That's our hook to load it on demand. + +### Comparison to the old approach + +In the old code, there was no `__getattr__`. There didn't need to be — all submodules were already loaded into the namespace by the `from . import` statements. `aws_s3` was always found in step 1. + +--- + +## Line 10: `if name in _SUBMODULES:` + +### What this does + +Checks if the requested attribute name is one of our known submodules. This is a set membership test — O(1), instant. + +### Why we need this check + +`__getattr__` is called for ANY missing attribute, not just submodules. If someone writes `aws_cdk.nonexistent_thing`, we don't want to try importing it. We only want to lazily import names we know are valid submodules. + +--- + +## Line 11: `mod = _importlib.import_module(f".{name}", __name__)` + +### What `importlib.import_module` does + +It imports a module by name and returns the module object. It's the programmatic equivalent of the `import` statement. + +Source: [Python docs — importlib.import_module](https://docs.python.org/3/library/importlib.html#importlib.import_module) + +### What `f".{name}"` means + +This is an f-string (formatted string). If `name` is `"aws_s3"`, then `f".{name}"` becomes `".aws_s3"`. + +The leading dot (`.`) means "relative import" — import from the current package. This is equivalent to `from . import aws_s3`. + +### What `__name__` means + +`__name__` is a built-in variable that every Python module has. It contains the module's fully qualified name. For `aws_cdk/__init__.py`, `__name__` is `"aws_cdk"`. + +`importlib.import_module` needs this as the second argument to know what package the relative import is relative TO. It's saying: "import `.aws_s3` relative to the `aws_cdk` package." + +### What this is equivalent to + +```python +mod = _importlib.import_module(".aws_s3", "aws_cdk") +``` + +Which is equivalent to: + +```python +from . import aws_s3 +mod = aws_s3 +``` + +### How Python caches imports (sys.modules) + +When Python imports a module, it stores it in `sys.modules` (a global dictionary). If you import the same module again, Python returns the cached version from `sys.modules` without re-executing the file. This is Python's built-in import caching. + +Source: [Python docs — The import system](https://docs.python.org/3/reference/import.html) + +So `importlib.import_module` is safe to call multiple times — the second call just returns the cached module. But we add our own caching too (next line) to avoid even calling `__getattr__` a second time. + +--- + +## Line 12: `globals()[name] = mod` + +### What `globals()` is + +`globals()` returns a dictionary representing the current module's global namespace. It's a live reference — modifying it actually modifies the module's namespace. + +Source: [Python docs — globals()](https://docs.python.org/3/library/functions.html#globals) + +For a module, `globals()` is the same as the module's `__dict__`. It contains every variable, function, and class defined at the module level. + +### What this line does + +It adds the imported module to the module's namespace. After `globals()["aws_s3"] = mod`, the module now has `aws_s3` as a regular attribute. + +### Why this is "caching" + +Remember Python's lookup order: +1. Check `__dict__` (globals) +2. If not found, call `__getattr__` + +After we do `globals()[name] = mod`, the next time someone accesses `aws_cdk.aws_s3`, Python finds it in step 1 and **never calls `__getattr__` again** for that name. The lazy loading only happens once per submodule. + +### How caching worked before (in the old approach) + +In the old code with `from . import aws_s3`, Python automatically put `aws_s3` into the module's globals when the import statement executed. So it was "cached" from the start — but at the cost of loading everything upfront. + +Our approach achieves the same end state (module in globals), but defers it until first access. + +### Why not just rely on `sys.modules` caching? + +`sys.modules` caching means `importlib.import_module` won't re-execute the file. But without `globals()[name] = mod`, Python would still call `__getattr__` every single time someone accesses `aws_cdk.aws_s3` (because it's not in the module's `__dict__`). That would add overhead on every access. By putting it in globals, we make subsequent accesses as fast as if we'd done the eager import. + +--- + +## Line 13: `return mod` + +### What this does + +Returns the imported module to whoever asked for it. If the user wrote `aws_cdk.aws_s3.Bucket(...)`, Python called `__getattr__("aws_s3")`, we imported the module, cached it, and now return it. Python then continues with `.Bucket(...)` on the returned module. + +--- + +## Line 14: `raise AttributeError(f"module {__name__!r} has no attribute {name!r}")` + +### Why we raise an error + +If someone accesses `aws_cdk.totally_fake_thing`, the name won't be in `_SUBMODULES`. We need to tell Python "this attribute doesn't exist." The way to do that is by raising `AttributeError`. + +### Why specifically `AttributeError` + +This is a Python protocol requirement. `__getattr__` MUST raise `AttributeError` for names it can't handle. Python relies on this: + +- `hasattr(aws_cdk, "fake")` works by calling `__getattr__("fake")` and checking if it raises `AttributeError`. If it does, `hasattr` returns `False`. If we raised a different exception (like `ValueError`), `hasattr` would crash instead of returning `False`. +- `getattr(aws_cdk, "fake", default_value)` works the same way — it catches `AttributeError` and returns the default. + +### Did the old code raise this error? + +Not explicitly — but the behavior was the same. In the old code, if you accessed `aws_cdk.totally_fake_thing`, Python would look in the module's `__dict__`, not find it, and raise `AttributeError` automatically (since there was no `__getattr__` to call). Now we have `__getattr__`, so we need to raise the error ourselves for unknown names. + +### What `{__name__!r}` means + +The `!r` is a format specifier that adds quotes around the value. `__name__` is `"aws_cdk"`, so `{__name__!r}` produces `'aws_cdk'` (with quotes). The error message looks like: + +``` +AttributeError: module 'aws_cdk' has no attribute 'totally_fake_thing' +``` + +This matches Python's standard error message format for missing module attributes. + +--- + +## Lines 16-17: `def __dir__() -> list[str]: return [*__all__, *_SUBMODULES]` + +### What `__dir__` does on a module + +When someone calls `dir(aws_cdk)`, Python calls the module's `__dir__()` function (if defined) to get the list of names to display. + +Source: [PEP 562 – Module `__getattr__` and `__dir__`](https://www.python.org/dev/peps/pep-0562/) + +### Why we need it + +Without `__dir__`, `dir(aws_cdk)` would only show names that are currently in the module's `__dict__`.

This is the standard PEP 562 caching pattern. - -3. **Assembly-loading modules excluded**: Modules with `loadAssembly=true` (the `_jsii` package) must eagerly import dependencies to initialize the jsii kernel. These are already guarded by an `assert` in `addPythonModule` and never have child submodules registered. - -4. **`import importlib` added to module header**: We add `import importlib as _importlib` to the standard imports block (only when the module has submodules). The underscore-prefixed alias avoids polluting the module namespace and is hidden by `publication.publish()`. - -5. **Submodule names remain in `__all__`**: This preserves `from aws_cdk import *` behavior. When Python processes `import *`, it accesses each name in `__all__`, which triggers `__getattr__` for submodule names, lazily loading them. - -## Components and Interfaces - -### Modified Component: `PythonModule.emit()` method - -**File**: `packages/jsii-pacmak/lib/targets/python.ts` - -The `emit()` method is the only method that changes. The modification replaces the final "Loading modules" block with the lazy loading code block. - -#### Current flow (end of `emit()`): -1. Emit `__all__` list -2. Call `publication.publish()` -3. Emit eager `from . import ` for each child module -4. Emit protocol stripper / intersection types - -#### New flow (end of `emit()`): -1. Emit `__all__` list (unchanged — submodule names still included) -2. Call `publication.publish()` (unchanged) -3. **If modules.length > 0**: Emit `_SUBMODULES` set, `__getattr__`, and `__dir__` -4. Emit protocol stripper / intersection types (unchanged) - -#### New import in module header - -When `this.modules.length > 0`, add to the imports block: - -```typescript -code.line('import importlib as _importlib'); -``` - -This is placed alongside the existing standard library imports (`abc`, `builtins`, `datetime`, etc.). - -#### Generated lazy loading block - -```python -_SUBMODULES = { - "submodule_a", - "submodule_b", -} - -def __getattr__(name: str) -> object: - if name in _SUBMODULES: - mod = _importlib.import_module(f".{name}", __name__) - globals()[name] = mod - return mod - raise AttributeError(f"module {__name__!r} has no attribute {name!r}") - -def __dir__() -> list[str]: - return [*__all__, *_SUBMODULES] -``` - -### Unchanged Components - -- **`PythonModule.addPythonModule()`**: No changes. Submodule registration logic is unaffected. -- **`PythonModule.emitDependencyImports()`**: No changes. Assembly-loading modules continue to eagerly import dependencies. -- **`PythonModule.emitRequiredImports()`**: No changes. Cross-submodule type imports (used in type annotations) remain eager. -- **`type-name.ts`**: No changes.

The existing `PythonModule` class fields are sufficient: - -- `this.modules: PythonModule[]` — already tracks child submodules -- `this.loadAssembly: boolean` — already distinguishes assembly-loading modules -- `this.pythonName: string` — used to compute relative submodule short names - -The only new generated Python artifact is the `_SUBMODULES` set literal, which is a simple set of string constants derived from `this.modules`. - -## Correctness Properties - -*A property is a characteristic or behavior that should hold true across all valid executions of a system — essentially, a formal statement about what the system should do.

This is the standard Python protocol for missing attributes and ensures that `hasattr()`, `getattr(mod, name, default)`, and try/except patterns work correctly. - -```python -raise AttributeError(f"module {__name__!r} has no attribute {name!r}") -``` - -### Import errors propagate naturally - -The generated `__getattr__` does NOT wrap `importlib.import_module` in a try/except. If a submodule fails to import (e.g., missing dependency, syntax error, jsii type registration failure), the original `ImportError` or other exception propagates to the caller. This matches the behavior of eager `from . import` statements and satisfies Requirement 3.3. - -### No silent fallback - -There is no fallback mechanism. If a submodule listed in `_SUBMODULES` cannot be imported, the error is surfaced immediately. This is intentional — silent failures would mask real problems in the generated packages. - -## Testing Strategy - -### Snapshot Tests (Primary validation) - -The existing snapshot test infrastructure (`packages/jsii-pacmak/test/generated-code/target-python.test.ts`) is the primary validation mechanism. It generates Python code for all test fixture packages (`@scope/jsii-calc-base-of-base`, `@scope/jsii-calc-base`, `@scope/jsii-calc-lib`, `jsii-calc`) and compares against stored snapshots. - -**After this change:** -- All snapshots will be updated to reflect the new lazy loading pattern -- The mypy check that runs on generated code will validate type correctness of `__getattr__` and `__dir__` -- The pyright check (`python-pyright.test.ts`) will validate type checker compatibility - -### Property-Based Tests - -Property-based tests will validate the correctness properties using `fast-check` (already available in the jsii monorepo's test infrastructure via Jest). - -Each property test will: -- Generate random inputs (submodule name lists, module configurations) -- Invoke the code generation logic -- Assert the property holds across 100+ iterations - -**Configuration:** -- Library: `fast-check` -- Minimum iterations: 100 per property -- Each test tagged with: `Feature: python-lazy-imports, Property {N}: {description}` - -**Property tests to implement:** - -1. **Property 1 test**: Generate random arrays of valid Python identifier strings as submodule names. Create a `PythonModule` with those submodules, run `emit()`, and verify: - - The output contains a `_SUBMODULES` set with exactly those names, sorted - - The output does NOT contain `from . import ` for any of those names - -2. **Property 2 test**: Generate random arrays of submodule names. Run `emit()` and verify every submodule short name appears in the `__all__` list. - -3. **Property 3 test**: Generate module configurations with `loadAssembly=true`. Run `emit()` and verify the output contains none of: `_SUBMODULES`, `def __getattr__`, `def __dir__`. - -4. **Property 4 test**: For a given assembly fixture, run code generation twice and verify the outputs are identical. (This can also be validated as a simpler determinism check by running emit twice on the same PythonModule configuration.) - -### Unit Tests (Example-based) - -Example-based unit tests for specific scenarios: - -- Module with submodules generates `__getattr__` with correct `importlib.import_module(f".{name}", __name__)` pattern -- Module with submodules generates `__dir__` returning `[*__all__, *_SUBMODULES]` -- Module with zero submodules generates no lazy loading code -- `__getattr__` raises `AttributeError` for unknown names (code structure check) -- `publication.publish()` appears before the lazy loading block -- `import importlib as _importlib` is added to imports when submodules exist -- `import importlib as _importlib` is NOT added when no submodules exist -- The `from ..._jsii import *` statement is preserved in non-assembly modules - -### Integration Tests (Existing) - -The existing integration test suite (compliance tests, runtime tests) validates end-to-end behavior: - -- `from aws_cdk import aws_s3` works -- `import aws_cdk.aws_s3` works -- `from aws_cdk import *` loads all submodules -- jsii type registration works on first access -- Type marshaling and cross-language callbacks function correctly - -These tests run against the generated packages and exercise the actual lazy loading at runtime. - - - -## Implementation Notes - -### Note 1: Dotted imports bypass `__getattr__` - -`import aws_cdk.aws_s3` (the dotted form) does NOT go through `__getattr__`. Python's import system resolves subpackages directly by looking for the directory on disk. This means the dotted import pattern works without any special handling from our side. No action needed — just be aware that `__getattr__` only fires for attribute access (`aws_cdk.aws_s3`) and `from aws_cdk import aws_s3`, not for `import aws_cdk.aws_s3`. - -### Note 2: Cross-module type deserialization (verify during implementation) - -If a method returns a type from a module the user never explicitly imported (e.g., an `aws_s3.Bucket` method returns an `aws_iam.Role`), the jsii runtime needs to deserialize that type. Currently this works because `aws_iam` was eagerly loaded. With lazy loading, `aws_iam` might not be loaded yet. - -The jsii Python runtime resolves types by FQN and should trigger imports as needed, so this is expected to work. However, add a test case during implementation that exercises this scenario: call a method that returns a type from an unimported submodule and verify it deserializes correctly. diff --git a/.kiro/specs/python-lazy-imports/requirements.md b/.kiro/specs/python-lazy-imports/requirements.md deleted file mode 100644 index 2def29721f..0000000000 --- a/.kiro/specs/python-lazy-imports/requirements.md +++ /dev/null @@ -1,100 +0,0 @@ -# Requirements Document - -## Introduction - -This feature replaces eager submodule imports in jsii-pacmak's Python code generator with lazy loading using Python PEP 562 module-level `__getattr__`.

WHEN a PythonModule has one or more child Submodules, THE Code_Generator SHALL emit a `_SUBMODULES` set literal containing the short names of all direct child Submodules instead of eager `from . import ` statements. -2. WHEN a PythonModule has one or more child Submodules, THE Code_Generator SHALL emit a module-level `__getattr__` function that imports the requested Submodule via `importlib.import_module` when the attribute name is found in `_SUBMODULES`. -3. WHEN `__getattr__` successfully imports a Submodule, THE Lazy_Loader SHALL cache the imported module in `globals()` so that subsequent accesses do not repeat the import. -4. WHEN `__getattr__` receives a name not in `_SUBMODULES`, THE Lazy_Loader SHALL raise an `AttributeError` with a message identifying the module and the missing attribute name. -5. WHEN a PythonModule has zero child Submodules, THE Code_Generator SHALL NOT emit the `_SUBMODULES` set, `__getattr__`, or `__dir__` functions. - -### Requirement 2: Preserve Module Introspection and Discoverability - -**User Story:** As a Python developer, I want `dir()`, tab-completion, and `from aws_cdk import *` to continue listing all submodules and public names, so that IDE tooling and interactive exploration remain functional. - -#### Acceptance Criteria - -1. WHEN a PythonModule has child Submodules, THE Code_Generator SHALL emit a module-level `__dir__` function that returns the union of `__all__` and the contents of `_SUBMODULES`. -2. THE Code_Generator SHALL continue to include Submodule short names in the `__all__` list so that `from import *` triggers lazy loading of all Submodules. -3. THE Code_Generator SHALL continue to call `publication.publish()` after defining `__all__` so that non-public names remain hidden from `dir()` output. - -### Requirement 3: Ensure jsii Type Registration on Demand - -**User Story:** As a CDK library author, I want jsii types to be registered with the jsii_Runtime when their containing module is first accessed, so that type marshaling and cross-language callbacks work correctly without eager loading. - -#### Acceptance Criteria - -1. WHEN a Submodule is lazily imported via `__getattr__`, THE Lazy_Loader SHALL trigger the same Type_Registration side effects that occur during an eager import of that Submodule. -2. WHEN the jsii_Runtime needs to deserialize a type from a Submodule that has not yet been lazily imported, THE jsii_Runtime SHALL be able to resolve the type by triggering the import of the containing Submodule. -3. IF a Type_Registration fails during lazy import, THEN THE Lazy_Loader SHALL propagate the original exception without suppressing it. - -### Requirement 4: Maintain Backwards Compatibility - -**User Story:** As an existing CDK Python user, I want my current code to continue working without modification after upgrading to a version with lazy imports, so that I do not experience regressions. - -#### Acceptance Criteria - -1. THE Code_Generator SHALL produce modules where `from aws_cdk import aws_s3` continues to work and returns the same module object as `import aws_cdk; aws_cdk.aws_s3`. -2. THE Code_Generator SHALL produce modules where `import aws_cdk.aws_s3` continues to work and populates `aws_cdk.aws_s3` as an attribute of the `aws_cdk` module. -3. THE Code_Generator SHALL produce modules where `from aws_cdk import *` loads all Submodules and makes them available in the caller's namespace. -4. WHEN a user accesses a Submodule attribute (e.g., `aws_cdk.aws_s3.Bucket`), THE Lazy_Loader SHALL return the same object that would have been returned under eager loading. -5. THE Code_Generator SHALL produce modules that are compatible with Python 3.8 and later versions. - -### Requirement 5: Support IDE and Type Checker Compatibility - -**User Story:** As a Python developer using mypy or pyright, I want type checking and autocomplete to work correctly with lazily loaded modules, so that my development experience is not degraded. - -#### Acceptance Criteria - -1. THE Code_Generator SHALL emit `__getattr__` and `__dir__` functions with type annotations that conform to PEP_562 so that type checkers recognize the module as supporting dynamic attribute access. -2. THE Code_Generator SHALL continue to emit type stub information (via `__all__` and existing type annotations) so that static analysis tools can resolve Submodule names. - -### Requirement 6: Preserve Assembly-Loading Module Behavior - -**User Story:** As a jsii-pacmak maintainer, I want the root assembly-loading module (the `_jsii` package loader) to remain unchanged, so that jsii assembly initialization is not affected by lazy loading. - -#### Acceptance Criteria - -1. WHEN a PythonModule has `loadAssembly` set to true, THE Code_Generator SHALL NOT apply lazy loading to that module and SHALL continue to emit eager dependency imports. -2. WHEN a PythonModule does not load an assembly, THE Code_Generator SHALL apply lazy loading to its child Submodule imports while preserving the eager `from ..._jsii import *` statement that loads the jsii assembly bindings. - -### Requirement 7: Generate Correct Relative Imports in Lazy Loader - -**User Story:** As a jsii-pacmak maintainer, I want the lazy loader to use relative imports consistent with the existing code generation strategy, so that the generated packages work in both pip-installed and bazel-managed environments. - -#### Acceptance Criteria - -1. THE Lazy_Loader SHALL use `importlib.import_module` with a relative import path (e.g., `f".{name}"`) and the current module's `__name__` as the package anchor. -2. THE Lazy_Loader SHALL produce import behavior equivalent to the current `from . import ` pattern so that `pkgutil.extend_path` namespace package resolution continues to function. - -### Requirement 8: Round-Trip Consistency of Generated Code - -**User Story:** As a jsii-pacmak maintainer, I want the generated Python code to be deterministic and reviewable, so that code generation changes can be validated in snapshot tests. - -#### Acceptance Criteria - -1.

You write code like: - -```python -bucket = aws_s3.Bucket(self, "MyBucket", versioned=True) -``` - -And CDK turns that into a CloudFormation template that AWS uses to create the actual S3 bucket. The process of turning your code into a template is called **synthesis** (`cdk synth`). - ---- - -## Part 2: What is jsii? - -CDK is written in **TypeScript**. But AWS wants customers to use CDK in Python, Java, C#, and Go too. Rather than maintaining 5 separate codebases, they built **jsii** — a system that: - -1. Takes the TypeScript CDK library -2. Generates wrapper libraries in each target language -3. At runtime, the Python/Java/C#/Go code talks to the actual TypeScript code running in a Node.js process behind the scenes - -So when a Python user writes `aws_s3.Bucket(self, "MyBucket")`, under the hood: -- The Python `Bucket` class is a thin wrapper -- It sends a message to a Node.js child process: "create a Bucket object with these args" -- Node.js runs the real TypeScript `Bucket` constructor -- The result is sent back to Python - ---- - -## Part 3: What is jsii-pacmak? - -**pacmak** = "package maker."

Specifically the import aws_cdk line. Familiarize yourself with virtual envs. - -**What this means:** - -The goal is to feel the problem firsthand. It's one thing to be told "imports are slow" — it's another to sit there watching your terminal hang for 6 seconds on a single `import` statement. - -**The commands (full sequence):** - -```bash -$ mkdir my-project -$ cd my-project -$ npx cdk@latest init app --language=python -$ source .venv/bin/activate -$ python -m pip install -r requirements.txt -$ time python -c "import aws_cdk" # ← feel the pain -``` - -Note: `npx cdk@latest init --language=python` and the official docs' `cdk init app --language python` do the same thing. `npx cdk@latest` runs the CDK CLI without installing it globally. `app` is the default template so omitting it is fine. - -**What `cdk init` creates:** - -``` -my-project/ -├── app.py ← entry point, has "import aws_cdk" -├── cdk.json ← CDK config -├── requirements.txt ← says "install aws-cdk-lib" -├── requirements-dev.txt -├── .venv/ ← Python virtual environment -├── .gitignore -├── README.md -├── source.bat -├── tests/ -│ └── unit/ -│ └── test_my_project_stack.py -└── my_project/ ← your app's Python package - ├── __init__.py - └── my_project_stack.py ← your stack definition -``` - -The subdirectory (`my_project/`) uses your project folder's name with hyphens converted to underscores (Python identifiers can't have hyphens). - -**What is a virtual environment?** - -A Python virtual environment (`.venv/`) is an isolated directory where pip installs packages. It keeps your project's dependencies separate from your system Python. You activate it with `source .venv/bin/activate`. After that, `pip install` puts packages into `.venv/lib/python3.x/site-packages/` instead of your global Python. - -**What you observed:** - -``` -$ time python -c "import aws_cdk" -python -c "import aws_cdk" 4.35s user 1.65s system 98% cpu 6.111 total -``` - -6.1 seconds for a single import. For comparison, `import json` takes ~0.02s and `import boto3` takes ~0.3s. CDK is 20x slower than boto3 and 300x slower than a standard library module. - -Every `cdk synth`, `cdk deploy`, `cdk diff` pays this tax before doing anything useful. - ---- - -### Phase 2: SEE THE BUILD POV - -**What your lead said:** -> Check out the CDK repository and build at least up to aws-cdk-lib: -> `$ yarn` -> `$ npx nx run aws-cdk-lib:build` -> Run pacmak to generate the Python code: -> `$ npx jsii-pacmak --targets python --code-only` -> Then have a look at what it generated in dist/python. - -**What this means:** - -You're looking at the **producer** side. The question is: where did that installed package come from? How was it built? - -**Step by step:** - -1. **`yarn`** — The CDK repo is a monorepo (one git repo, hundreds of packages). `yarn` installs all Node.js dependencies. Like `pip install` but for the whole project. - -2. **`npx nx run aws-cdk-lib:build`** — Compiles `aws-cdk-lib` from TypeScript. This produces: - - Compiled JavaScript (`.js` files) - - A **`.jsii` assembly file** — a massive JSON file (~50MB) describing every public type in the library - -3. **`npx jsii-pacmak --targets python --code-only`** — Reads the `.jsii` assembly and generates a complete Python package. `--targets python` means "only Python." `--code-only` means "just generate `.py` files, don't package into a wheel." - -**What it generates in `dist/python/`:** - -``` -dist/python/src/aws_cdk/ -├── __init__.py ← the root module (the slow one) -├── _jsii/ -│ └── __init__.py ← assembly loader -├── aws_s3/ -│ └── __init__.py ← S3 constructs -├── aws_lambda/ -│ └── __init__.py ← Lambda constructs -├── aws_ec2/ -│ └── __init__.py ← EC2 constructs -└── ... (~300 more directories) -``` - -This is the **exact same code** that ends up on PyPI and gets installed into users' virtual environments. The package published to PyPI is just this generated code, packaged up. - -**The key insight:** The Python code users install was NOT written by a human. It was generated by jsii-pacmak. To fix the slowness, you don't edit the Python files — you edit the TypeScript program that generates them. - -**Shortcut:** You can skip cloning the CDK repo for now. The generated output is already in your Phase 1 project at `.venv/lib/python3.x/site-packages/aws_cdk/`. It's the same code. - ---- - -### Phase 3: TRACE THIS BACK TO SOURCE - -**What your lead said:** -> Go and find the source for jsii-pacmak's Python generation and go peruse it. See how it maps to the code you saw in dist/python (and potentially in .venv/site-packages/python3.13/aws_cdk of your example project if you care to look) - -**What this means:** - -Connect the dots: which line of TypeScript code in jsii-pacmak produced which line of Python output? - -**The generator file:** - -``` -packages/jsii-pacmak/lib/targets/python.ts -``` - -This is ~3500 lines of TypeScript. The key class is `PythonModule`, which represents one Python module (one `__init__.py` file). - -**How the generator works:** - -It uses a `CodeMaker` object (called `code`) that's a string builder with indentation tracking: - -```typescript -code.line('import abc'); // writes: import abc -code.line('import builtins'); // writes: import builtins -code.openBlock('class Foo'); // writes: class Foo: (and increases indent) -code.line('pass'); // writes: pass -code.closeBlock(); // decreases indent -``` - -**The specific code that causes the problem (line ~1929 in python.ts):** - -```typescript -// Finally, we'll load all registered python modules -if (this.modules.length > 0) { - code.line( - '# Loading modules to ensure their types are registered with the jsii runtime library', - ); - for (const module of this.modules.sort((l, r) => - l.pythonName.localeCompare(r.pythonName), - )) { - const submodule = module.pythonName.substring( - this.pythonName.length + 1, - ); - code.line(`from . import ${submodule}`); - } -} -``` - -This loop iterates over every child module (~300 for aws-cdk-lib) and writes `from . import ` for each one. That's what produces the 300+ eager import lines at the bottom of `aws_cdk/__init__.py`. - -**The mapping:** - -| TypeScript generator code | Generated Python output | -|---|---| -| `code.line('import abc')` | `import abc` | -| `code.line('import jsii')` | `import jsii` | -| `code.line('publication.publish()')` | `publication.publish()` | -| `code.line(\`from . import ${submodule}\`)` in a loop | `from . import aws_s3`
`from . import aws_lambda`

... | - ---- - -## Part 6: The User's Flow (What Happens When They Run `cdk synth`) - -### The user has this file: - -```python -# app.py -from aws_cdk import App, Stack, aws_s3 - -class MyStack(Stack): - def __init__(self, scope, id): - super().__init__(scope, id) - aws_s3.Bucket(self, "MyBucket") - -app = App() -MyStack(app, "MyStack") -app.synth() -``` - -### They run: - -```bash -$ cdk synth -``` - -### Step 1: CDK CLI starts - -`cdk` is a Node.js program. It reads `cdk.json` which says: - -```json -{ "app": "python3 app.py" } -``` - -So the CDK CLI spawns a child process: `python3 app.py` - -### Step 2: Python starts executing `app.py` - -Python reads the first line: - -```python -from aws_cdk import App, Stack, aws_s3 -``` - -To execute this, Python needs to find and load the `aws_cdk` module. - -### Step 3: Python finds `aws_cdk` - -Python looks in `.venv/lib/python3.x/site-packages/` and finds the `aws_cdk/` directory. It opens `aws_cdk/__init__.py` and starts executing it **top to bottom**. - -### Step 4: Python executes `aws_cdk/__init__.py` - -This file is ~50,000 lines long. Here's what's in it (simplified): - -```python -# Line 1-10: standard imports -import abc -import builtins -import typing -import jsii -import publication - -# Line 11-45000: class definitions for root-level types -class App: - def __init__(self, ...): jsii.create(...) - -class Stack: - def __init__(self, ...): jsii.create(...) - -class CfnOutput: - ... - -# ... thousands more classes ... - -# Line 45001: export list -__all__ = ["App", "Stack", "CfnOutput", "aws_s3", "aws_lambda", ...] - -# Line 45002: hide non-public names -publication.publish() - -# Line 45003-45300: THE PROBLEM -from . import aws_accessanalyzer # ← Python goes and loads this entire module -from . import aws_acmpca # ← and this one -from . import aws_amplify # ← and this one -from . import aws_apigateway # ← and this one -# ... 300+ more lines like this -from . import aws_s3 # ← the user actually needs this one -# ... more ... -from . import aws_xray # ← and this one too -``` - -### Step 5: What happens at each `from . import` line - -When Python hits `from . import aws_s3`, it: - -1. Opens `aws_cdk/aws_s3/__init__.py` -2. Executes it top to bottom -3. That file defines ~200 classes (Bucket, BucketPolicy, CfnBucket, CfnBucketPolicy, etc.) -4. Each class definition triggers jsii registration (telling the jsii runtime "this Python class maps to this TypeScript type") -5. Returns back to `aws_cdk/__init__.py` and moves to the next line - -This happens **for every single `from . import` line**. 300+ times. Each submodule has dozens to hundreds of classes. Total: thousands of class definitions, thousands of jsii registrations. - -**The user only needed `App`, `Stack`, and `aws_s3`. But Python loaded all 300+ submodules because the `__init__.py` told it to.** - -### Step 6: Python finally finishes loading `aws_cdk` - -After 6 seconds, Python has executed all 300+ imports. Now it returns to `app.py` and resolves the names the user asked for: `App`, `Stack`, `aws_s3`. These are now available. - -### Step 7: User code runs - -```python -app = App() # sends "create App" to Node.js -MyStack(app, "MyStack") # sends "create Stack" to Node.js -aws_s3.Bucket(self, "MyBucket") # sends "create Bucket" to Node.js -app.synth() # tells Node.js to produce CloudFormation -``` - -Each of these calls goes through the jsii runtime to Node.js, which runs the real TypeScript code and produces a CloudFormation template. - -### Step 8: Output - -The CDK CLI receives the CloudFormation template from the Python process and prints it (or deploys it). - -### Where the 6 seconds went - -| Time | What's happening | -|---|---| -| 0.0s - 0.1s | Python starts, finds `aws_cdk` | -| 0.1s - 0.5s | Executes root-level class definitions (App, Stack, etc.) | -| 0.5s - 6.0s | **Loads 300+ submodules the user never asked for** | -| 6.0s - 6.1s | User code actually runs | - ---- - -## Part 7: The Build Pipeline (Producer Side) - -This is how the Python package gets created and published: - -``` -TypeScript source code (hand-written by CDK team) - │ - ▼ - tsc + jsii compiler - │ - ▼ - .jsii assembly (JSON manifest of the entire API — ~50MB) - │ - ▼ - jsii-pacmak (code generator — THIS IS WHAT YOU'RE MODIFYING) - │ - ▼ - Python source code (generated, not hand-written) - │ - ▼ - wheel/sdist (packaged for PyPI) - │ - ▼ - pip install (what users get) -``` - -### What the .jsii assembly contains - -A machine-readable catalog of every public type: - -```json -{ - "fqn": "aws-cdk-lib.aws_s3.Bucket", - "kind": "class", - "name": "Bucket", - "initializer": { - "parameters": [ - { "name": "scope", "type": { "fqn": "constructs.Construct" } }, - { "name": "id", "type": { "primitive": "string" } } - ] - }, - "properties": [ - { "name": "bucketArn", "type": { "primitive": "string" }, "immutable": true } - ] -} -``` - -### What pacmak generates from it - -```python -class Bucket(Resource): - def __init__(self, scope: Construct, id: str) -> None: - jsii.create(self.__class__, self, [scope, id]) - - @property - def bucket_arn(self) -> str: - return jsii.get(self, "bucketArn") -``` - -The generated Python class is a **puppet**. It doesn't contain business logic. When you call `Bucket(scope, id)`, the Python code sends a message to Node.js saying "create a Bucket with these args." Node.js runs the real TypeScript implementation and sends back a reference. - ---- - -## Part 8: What We're Changing - -We're modifying the TypeScript loop in `packages/jsii-pacmak/lib/targets/python.ts` so that instead of generating: - -```python -from . import aws_s3 -from . import aws_lambda -from . import aws_ec2 -# ... 300+ more -``` - -It generates: - -```python -import importlib as _importlib - -_SUBMODULES = {"aws_s3", "aws_lambda", "aws_ec2", ...} - -def __getattr__(name): - if name in _SUBMODULES: - mod = _importlib.import_module(f".{name}", __name__) - globals()[name] = mod - return mod - raise AttributeError(f"module {__name__!r} has no attribute {name!r}") - -def __dir__(): - return [*__all__, *_SUBMODULES] -``` - -### How this changes the user's experience - -With lazy loading, the user's `cdk synth` flow becomes: - -1. Python executes `from aws_cdk import App, Stack, aws_s3` -2. Python opens `aws_cdk/__init__.py` and starts executing it -3. It defines root-level classes (`App`, `Stack`, etc.) -4. It defines `_SUBMODULES = {"aws_s3", "aws_lambda", ...}` and `__getattr__` — **no actual imports happen** -5. Python sees the user wants `aws_s3` → calls `__getattr__("aws_s3")` → imports just that one module -6. Done. **~0.2 seconds instead of 6.** - -| Time | What's happening (after fix) | -|---|---| -| 0.0s - 0.1s | Python starts, finds `aws_cdk` | -| 0.1s - 0.2s | Executes root-level class definitions + defines `__getattr__` | -| 0.2s - 0.3s | Loads `aws_s3` only (because user asked for it) | -| 0.3s - 0.4s | User code runs | - -6 seconds → 0.4 seconds. The user's code doesn't change at all. - ---- - -## Part 9: Why the Eager Imports Existed in the First Place - -The comment in the generated code says: - -```python -# Loading modules to ensure their types are registered with the jsii runtime library -``` - -When the jsii runtime receives an object from Node.js (e.g., a method returns an `iam.Role`), it needs to know which Python class corresponds to `aws-cdk-lib.aws_iam.Role`. This mapping is built when each Python class is defined — the `@jsii.implements` decorator registers it. - -The original thinking was: "load everything upfront so the runtime always knows about every type." This is correct but wasteful. - -**Why lazy loading is safe:** By the time the jsii runtime needs to deserialize a type from `aws_s3`, the user must have already accessed `aws_s3` (otherwise how would they have gotten an `aws_s3.Bucket` in the first place?). So the module will already be imported and its types registered. - ---- - -## Part 10: Summary - -- **The problem:** `import aws_cdk` takes 6 seconds because it eagerly loads 300+ submodules -- **The root cause:** jsii-pacmak generates `from . import ` for every submodule -- **The fix:** Change pacmak to generate lazy loading (`__getattr__`) instead of eager imports -- **Where to fix it:** `packages/jsii-pacmak/lib/targets/python.ts`, the `PythonModule.emit()` method, lines ~1929-1946 -- **Impact:** 6 seconds → ~0.4 seconds on every `cdk synth`/`deploy`/`diff` -- **User impact:** Zero. Their code doesn't change. They just get faster imports after upgrading.

It lets you import modules using code (dynamically) rather than using the `import` statement. - -Source: [Python docs — importlib](https://docs.python.org/3/library/importlib.html) - -### Why `as _importlib` (the underscore prefix) - -The `as _importlib` renames it with an underscore prefix. In Python, underscore-prefixed names are a convention meaning "private / internal." The `publication.publish()` call later in the file hides all names NOT in `__all__` from `dir()` and tab-completion. Since `_importlib` starts with an underscore and isn't in `__all__`, it becomes invisible to users. - -Without the underscore, users doing `dir(aws_cdk)` would see `importlib` listed as if it were part of the CDK API. That would be confusing. - -### Why we need it at all - -We need `importlib.import_module()` to do the actual lazy import inside `__getattr__`. We can't use a regular `import` statement inside `__getattr__` because we need to do a **relative** import with a **dynamic** name (the name comes from the function parameter). The `import` statement requires the module name to be hardcoded at write time. - -### Comparison to the old approach - -In the old code, there was no `import importlib` because the imports were done with regular `from . import aws_s3` statements — no dynamic importing needed. - ---- - -## Lines 3-7: `_SUBMODULES = {"aws_s3", "aws_lambda", "aws_ec2"}` - -### What this is - -A Python **set literal** containing strings. A set is an unordered collection of unique items. Looking up whether something is in a set is O(1) — instant, regardless of how many items are in the set. - -### Why a set and not a list - -With 300+ submodule names, we need fast lookup. `if name in _SUBMODULES` is called every time someone accesses an attribute that doesn't exist yet. With a set, this check is instant. With a list, Python would scan through all 300 items one by one. - -### Why underscore prefix - -Same reason as `_importlib` — it's an internal implementation detail, not part of the public API. Hidden by `publication.publish()`. - -### What this replaces - -Previously, there was no `_SUBMODULES` set. The submodule names only existed as part of the `from . import aws_s3` statements. Those statements both declared the names AND loaded the modules. Now we separate the two concerns: `_SUBMODULES` declares the names, and `__getattr__` loads them on demand. - -### Why this is fast - -Creating a set of 300 strings takes microseconds. No files are opened, no modules are loaded, no classes are defined. It's just storing text in memory. - ---- - -## Line 9: `def __getattr__(name: str) -> object:` - -### What `__getattr__` is (on a class) - -You might know `__getattr__` from classes. On a class, it's a special method that Python calls when you access an attribute that doesn't exist: - -```python -class Foo: - def __getattr__(self, name): - return f"you asked for {name}" - -f = Foo() -print(f.xyz) # prints "you asked for xyz" -``` - -### What `__getattr__` is (on a module) — PEP 562 - -Since Python 3.7, you can define `__getattr__` at the **module level** (not inside a class). Python calls it when someone accesses an attribute on the module that doesn't exist in the module's namespace. - -Source: [PEP 562 – Module `__getattr__` and `__dir__`](https://www.python.org/dev/peps/pep-0562/) - -### When does Python call it? - -Python has a lookup order for module attributes: - -1. First, check the module's `__dict__` (its global namespace — all variables, functions, classes defined in the file) -2. If not found there, call `__getattr__(name)` if it exists -3. If `__getattr__` raises `AttributeError`, Python raises `AttributeError` to the caller - -### Why this is the key to lazy loading - -When the file first executes, `aws_s3` is NOT in the module's namespace (because we didn't import it). So when someone writes `aws_cdk.aws_s3`, Python doesn't find `aws_s3` in step 1, and calls `__getattr__("aws_s3")` in step 2. That's our hook to load it on demand. - -### Comparison to the old approach - -In the old code, there was no `__getattr__`. There didn't need to be — all submodules were already loaded into the namespace by the `from . import` statements. `aws_s3` was always found in step 1. - ---- - -## Line 10: `if name in _SUBMODULES:` - -### What this does - -Checks if the requested attribute name is one of our known submodules. This is a set membership test — O(1), instant. - -### Why we need this check - -`__getattr__` is called for ANY missing attribute, not just submodules. If someone writes `aws_cdk.nonexistent_thing`, we don't want to try importing it. We only want to lazily import names we know are valid submodules. - ---- - -## Line 11: `mod = _importlib.import_module(f".{name}", __name__)` - -### What `importlib.import_module` does - -It imports a module by name and returns the module object. It's the programmatic equivalent of the `import` statement. - -Source: [Python docs — importlib.import_module](https://docs.python.org/3/library/importlib.html#importlib.import_module) - -### What `f".{name}"` means - -This is an f-string (formatted string). If `name` is `"aws_s3"`, then `f".{name}"` becomes `".aws_s3"`. - -The leading dot (`.`) means "relative import" — import from the current package. This is equivalent to `from . import aws_s3`. - -### What `__name__` means - -`__name__` is a built-in variable that every Python module has. It contains the module's fully qualified name. For `aws_cdk/__init__.py`, `__name__` is `"aws_cdk"`. - -`importlib.import_module` needs this as the second argument to know what package the relative import is relative TO. It's saying: "import `.aws_s3` relative to the `aws_cdk` package." - -### What this is equivalent to - -```python -mod = _importlib.import_module(".aws_s3", "aws_cdk") -``` - -Which is equivalent to: - -```python -from . import aws_s3 -mod = aws_s3 -``` - -### How Python caches imports (sys.modules) - -When Python imports a module, it stores it in `sys.modules` (a global dictionary). If you import the same module again, Python returns the cached version from `sys.modules` without re-executing the file. This is Python's built-in import caching. - -Source: [Python docs — The import system](https://docs.python.org/3/reference/import.html) - -So `importlib.import_module` is safe to call multiple times — the second call just returns the cached module. But we add our own caching too (next line) to avoid even calling `__getattr__` a second time. - ---- - -## Line 12: `globals()[name] = mod` - -### What `globals()` is - -`globals()` returns a dictionary representing the current module's global namespace. It's a live reference — modifying it actually modifies the module's namespace. - -Source: [Python docs — globals()](https://docs.python.org/3/library/functions.html#globals) - -For a module, `globals()` is the same as the module's `__dict__`. It contains every variable, function, and class defined at the module level. - -### What this line does - -It adds the imported module to the module's namespace. After `globals()["aws_s3"] = mod`, the module now has `aws_s3` as a regular attribute. - -### Why this is "caching" - -Remember Python's lookup order: -1. Check `__dict__` (globals) -2. If not found, call `__getattr__` - -After we do `globals()[name] = mod`, the next time someone accesses `aws_cdk.aws_s3`, Python finds it in step 1 and **never calls `__getattr__` again** for that name. The lazy loading only happens once per submodule. - -### How caching worked before (in the old approach) - -In the old code with `from . import aws_s3`, Python automatically put `aws_s3` into the module's globals when the import statement executed. So it was "cached" from the start — but at the cost of loading everything upfront. - -Our approach achieves the same end state (module in globals), but defers it until first access. - -### Why not just rely on `sys.modules` caching? - -`sys.modules` caching means `importlib.import_module` won't re-execute the file. But without `globals()[name] = mod`, Python would still call `__getattr__` every single time someone accesses `aws_cdk.aws_s3` (because it's not in the module's `__dict__`). That would add overhead on every access. By putting it in globals, we make subsequent accesses as fast as if we'd done the eager import. - ---- - -## Line 13: `return mod` - -### What this does - -Returns the imported module to whoever asked for it. If the user wrote `aws_cdk.aws_s3.Bucket(...)`, Python called `__getattr__("aws_s3")`, we imported the module, cached it, and now return it. Python then continues with `.Bucket(...)` on the returned module. - ---- - -## Line 14: `raise AttributeError(f"module {__name__!r} has no attribute {name!r}")` - -### Why we raise an error - -If someone accesses `aws_cdk.totally_fake_thing`, the name won't be in `_SUBMODULES`. We need to tell Python "this attribute doesn't exist." The way to do that is by raising `AttributeError`. - -### Why specifically `AttributeError` - -This is a Python protocol requirement. `__getattr__` MUST raise `AttributeError` for names it can't handle. Python relies on this: - -- `hasattr(aws_cdk, "fake")` works by calling `__getattr__("fake")` and checking if it raises `AttributeError`. If it does, `hasattr` returns `False`. If we raised a different exception (like `ValueError`), `hasattr` would crash instead of returning `False`. -- `getattr(aws_cdk, "fake", default_value)` works the same way — it catches `AttributeError` and returns the default. - -### Did the old code raise this error? - -Not explicitly — but the behavior was the same. In the old code, if you accessed `aws_cdk.totally_fake_thing`, Python would look in the module's `__dict__`, not find it, and raise `AttributeError` automatically (since there was no `__getattr__` to call). Now we have `__getattr__`, so we need to raise the error ourselves for unknown names. - -### What `{__name__!r}` means - -The `!r` is a format specifier that adds quotes around the value. `__name__` is `"aws_cdk"`, so `{__name__!r}` produces `'aws_cdk'` (with quotes). The error message looks like: - -``` -AttributeError: module 'aws_cdk' has no attribute 'totally_fake_thing' -``` - -This matches Python's standard error message format for missing module attributes. - ---- - -## Lines 16-17: `def __dir__() -> list[str]: return [*__all__, *_SUBMODULES]` - -### What `__dir__` does on a module - -When someone calls `dir(aws_cdk)`, Python calls the module's `__dir__()` function (if defined) to get the list of names to display. - -Source: [PEP 562 – Module `__getattr__` and `__dir__`](https://www.python.org/dev/peps/pep-0562/) - -### Why we need it - -Without `__dir__`, `dir(aws_cdk)` would only show names that are currently in the module's `__dict__`. Since submodules aren't loaded yet, they wouldn't appear. Tab-completion in IPython/Jupyter and IDE autocomplete rely on `dir()`, so submodules would be invisible to developers exploring the API. - -### What `[*__all__, *_SUBMODULES]` means - -The `*` operator unpacks a collection into a list. This creates a new list containing all items from `__all__` plus all items from `_SUBMODULES`. - -- `__all__` contains the public names (classes like `App`, `Stack`, plus submodule names) -- `_SUBMODULES` contains the submodule names - -There's overlap (submodule names are in both), but that's fine — it's just a display list. - -### Did the old code have `__dir__`? - -No. It didn't need one because all submodules were already loaded into globals, so `dir()` naturally included them. - ---- - -## Summary: Old vs New - -| Aspect | Old (eager) | New (lazy) | -|---|---|---| -| How submodules are declared | `from . import aws_s3` (loads immediately) | `_SUBMODULES = {"aws_s3"}` (just a string) | -| When submodules are loaded | All at once, during `import aws_cdk` | One at a time, when first accessed | -| How loading is triggered | Python's `import` statement | `__getattr__` + `importlib.import_module` | -| How results are cached | Automatically in globals by `import` | Manually via `globals()[name] = mod` | -| How missing attrs are handled | Python raises `AttributeError` automatically | We raise `AttributeError` in `__getattr__` | -| How `dir()` works | Shows all names (already in globals) | Custom `__dir__` returns `__all__` + `_SUBMODULES` | -| Import time for `aws_cdk` | ~6 seconds (loads 300 modules) | ~0.2 seconds (loads nothing) | - ---- - -## Sources - -- [PEP 562 – Module `__getattr__` and `__dir__`](https://www.python.org/dev/peps/pep-0562/) — The Python Enhancement Proposal that made module-level `__getattr__` possible (Python 3.7+) -- [Python docs — importlib.import_module](https://docs.python.org/3/library/importlib.html#importlib.import_module) — The function we use for dynamic imports -- [Python docs — globals()](https://docs.python.org/3/library/functions.html#globals) — Returns the module's global namespace dictionary -- [Python docs — The import system](https://docs.python.org/3/reference/import.html) — How Python's import system works, including `sys.modules` caching -- [Python docs — Customizing Module Attribute Access](https://docs.python.org/3/reference/datamodel.html#customizing-module-attribute-access) — The canonical documentation for module `__getattr__` and `__dir__` From 0cb34c8826d51a04d4b227455ef5035fbcc1703e Mon Sep 17 00:00:00 2001 From: dgandhi62 Date: Tue, 12 May 2026 15:38:36 -0400 Subject: [PATCH 08/18] fix: revert unrelated rosetta translation drift in non-Python snapshots --- .../__snapshots__/target-dotnet.test.js.snap | 36 +- .../__snapshots__/target-go.test.js.snap | 33 +- .../__snapshots__/target-java.test.js.snap | 22 +- .../__snapshots__/target-python.test.js.snap | 366 +++++++++--------- 4 files changed, 225 insertions(+), 232 deletions(-) diff --git a/packages/jsii-pacmak/test/generated-code/__snapshots__/target-dotnet.test.js.snap b/packages/jsii-pacmak/test/generated-code/__snapshots__/target-dotnet.test.js.snap index d93c3348f6..99778630c3 100644 --- a/packages/jsii-pacmak/test/generated-code/__snapshots__/target-dotnet.test.js.snap +++ b/packages/jsii-pacmak/test/generated-code/__snapshots__/target-dotnet.test.js.snap @@ -4992,19 +4992,17 @@ namespace Amazon.JSII.Tests.CalculatorNamespace /// Here's how you use it: /// /// /// /// I will repeat this example again, but in an /// /// - /// const calculator = new calc.Calculator(); - /// calculator.add(5); - /// calculator.mul(3); - /// // console.log(calculator.expression.value); + /// var calculator = new Calculator(); + /// calculator.Add(5); + /// calculator.Mul(3); /// [JsiiClass(nativeType: typeof(Amazon.JSII.Tests.CalculatorNamespace.Calculator), fullyQualifiedName: "jsii-calc.Calculator", parametersJson: "[{\\"docs\\":{\\"summary\\":\\"Initialization properties.\\"},\\"name\\":\\"props\\",\\"optional\\":true,\\"type\\":{\\"fqn\\":\\"jsii-calc.CalculatorProps\\"}}]")] public class Calculator : Amazon.JSII.Tests.CalculatorNamespace.Composition.CompositeOperation @@ -5772,7 +5770,8 @@ namespace Amazon.JSII.Tests.CalculatorNamespace /// CustomAttribute: hasAValue /// /// - /// function anExample() { + /// public void AnExample() + /// { /// } /// [JsiiClass(nativeType: typeof(Amazon.JSII.Tests.CalculatorNamespace.ClassWithDocs), fullyQualifiedName: "jsii-calc.ClassWithDocs")] @@ -7840,12 +7839,13 @@ namespace Amazon.JSII.Tests.CalculatorNamespace /// Multiple paragraphs are separated by an empty line. /// /// - /// const x = 12 + 44; - /// const s1 = "string"; - /// const s2 = "string \\nwith new newlines"; // see https://github.com/aws/jsii/issues/2569 - /// const s3 = \`string + /// var x = 12 + 44; + /// var s1 = "string"; + /// var s2 = @"string + /// with new newlines"; // see https://github.com/aws/jsii/issues/2569 + /// var s3 = @"string /// with - /// new lines\`; + /// new lines"; /// [JsiiClass(nativeType: typeof(Amazon.JSII.Tests.CalculatorNamespace.DocumentedClass), fullyQualifiedName: "jsii-calc.DocumentedClass")] public class DocumentedClass : DeputyBase @@ -17114,20 +17114,20 @@ namespace Amazon.JSII.Tests.CalculatorNamespace /// First, create a calculator: /// /// /// /// Then call some operations: /// /// /// ///

This is the standard PEP 562 caching pattern. + +3. **Assembly-loading modules excluded**: Modules with `loadAssembly=true` (the `_jsii` package) must eagerly import dependencies to initialize the jsii kernel. These are already guarded by an `assert` in `addPythonModule` and never have child submodules registered. + +4. **`import importlib` added to module header**: We add `import importlib as _importlib` to the standard imports block (only when the module has submodules). The underscore-prefixed alias avoids polluting the module namespace and is hidden by `publication.publish()`. + +5. **Submodule names remain in `__all__`**: This preserves `from aws_cdk import *` behavior. When Python processes `import *`, it accesses each name in `__all__`, which triggers `__getattr__` for submodule names, lazily loading them. + +## Components and Interfaces + +### Modified Component: `PythonModule.emit()` method + +**File**: `packages/jsii-pacmak/lib/targets/python.ts` + +The `emit()` method is the only method that changes.

Specifically the import aws_cdk line. Familiarize yourself with virtual envs. + +**What this means:** + +The goal is to feel the problem firsthand. It's one thing to be told "imports are slow" — it's another to sit there watching your terminal hang for 6 seconds on a single `import` statement. + +**The commands (full sequence):** + +```bash +$ mkdir my-project +$ cd my-project +$ npx cdk@latest init app --language=python +$ source .venv/bin/activate +$ python -m pip install -r requirements.txt +$ time python -c "import aws_cdk" # ← feel the pain +``` + +Note: `npx cdk@latest init --language=python` and the official docs' `cdk init app --language python` do the same thing. `npx cdk@latest` runs the CDK CLI without installing it globally. `app` is the default template so omitting it is fine. + +**What `cdk init` creates:** + +``` +my-project/ +├── app.py ← entry point, has "import aws_cdk" +├── cdk.json ← CDK config +├── requirements.txt ← says "install aws-cdk-lib" +├── requirements-dev.txt +├── .venv/ ← Python virtual environment +├── .gitignore +├── README.md +├── source.bat +├── tests/ +│ └── unit/ +│ └── test_my_project_stack.py +└── my_project/ ← your app's Python package + ├── __init__.py + └── my_project_stack.py ← your stack definition +``` + +The subdirectory (`my_project/`) uses your project folder's name with hyphens converted to underscores (Python identifiers can't have hyphens). + +**What is a virtual environment?** + +A Python virtual environment (`.venv/`) is an isolated directory where pip installs packages. It keeps your project's dependencies separate from your system Python. You activate it with `source .venv/bin/activate`. After that, `pip install` puts packages into `.venv/lib/python3.x/site-packages/` instead of your global Python. + +**What you observed:** + +``` +$ time python -c "import aws_cdk" +python -c "import aws_cdk" 4.35s user 1.65s system 98% cpu 6.111 total +``` + +6.1 seconds for a single import. For comparison, `import json` takes ~0.02s and `import boto3` takes ~0.3s. CDK is 20x slower than boto3 and 300x slower than a standard library module. + +Every `cdk synth`, `cdk deploy`, `cdk diff` pays this tax before doing anything useful. + +--- + +### Phase 2: SEE THE BUILD POV + +**What your lead said:** +> Check out the CDK repository and build at least up to aws-cdk-lib: +> `$ yarn` +> `$ npx nx run aws-cdk-lib:build` +> Run pacmak to generate the Python code: +> `$ npx jsii-pacmak --targets python --code-only` +> Then have a look at what it generated in dist/python. + +**What this means:** + +You're looking at the **producer** side. The question is: where did that installed package come from? How was it built? + +**Step by step:** + +1. **`yarn`** — The CDK repo is a monorepo (one git repo, hundreds of packages). `yarn` installs all Node.js dependencies. Like `pip install` but for the whole project. + +2. **`npx nx run aws-cdk-lib:build`** — Compiles `aws-cdk-lib` from TypeScript. This produces: + - Compiled JavaScript (`.js` files) + - A **`.jsii` assembly file** — a massive JSON file (~50MB) describing every public type in the library + +3. **`npx jsii-pacmak --targets python --code-only`** — Reads the `.jsii` assembly and generates a complete Python package. `--targets python` means "only Python." `--code-only` means "just generate `.py` files, don't package into a wheel." + +**What it generates in `dist/python/`:** + +``` +dist/python/src/aws_cdk/ +├── __init__.py ← the root module (the slow one) +├── _jsii/ +│ └── __init__.py ← assembly loader +├── aws_s3/ +│ └── __init__.py ← S3 constructs +├── aws_lambda/ +│ └── __init__.py ← Lambda constructs +├── aws_ec2/ +│ └── __init__.py ← EC2 constructs +└── ... (~300 more directories) +``` + +This is the **exact same code** that ends up on PyPI and gets installed into users' virtual environments. The package published to PyPI is just this generated code, packaged up. + +**The key insight:** The Python code users install was NOT written by a human. It was generated by jsii-pacmak. To fix the slowness, you don't edit the Python files — you edit the TypeScript program that generates them. + +**Shortcut:** You can skip cloning the CDK repo for now. The generated output is already in your Phase 1 project at `.venv/lib/python3.x/site-packages/aws_cdk/`. It's the same code. + +--- + +### Phase 3: TRACE THIS BACK TO SOURCE + +**What your lead said:** +> Go and find the source for jsii-pacmak's Python generation and go peruse it. See how it maps to the code you saw in dist/python (and potentially in .venv/site-packages/python3.13/aws_cdk of your example project if you care to look) + +**What this means:** + +Connect the dots: which line of TypeScript code in jsii-pacmak produced which line of Python output? + +**The generator file:** + +``` +packages/jsii-pacmak/lib/targets/python.ts +``` + +This is ~3500 lines of TypeScript. The key class is `PythonModule`, which represents one Python module (one `__init__.py` file). + +**How the generator works:** + +It uses a `CodeMaker` object (called `code`) that's a string builder with indentation tracking: + +```typescript +code.line('import abc'); // writes: import abc +code.line('import builtins'); // writes: import builtins +code.openBlock('class Foo'); // writes: class Foo: (and increases indent) +code.line('pass'); // writes: pass +code.closeBlock(); // decreases indent +``` + +**The specific code that causes the problem (line ~1929 in python.ts):** + +```typescript +// Finally, we'll load all registered python modules +if (this.modules.length > 0) { + code.line( + '# Loading modules to ensure their types are registered with the jsii runtime library', + ); + for (const module of this.modules.sort((l, r) => + l.pythonName.localeCompare(r.pythonName), + )) { + const submodule = module.pythonName.substring( + this.pythonName.length + 1, + ); + code.line(`from . import ${submodule}`); + } +} +``` + +This loop iterates over every child module (~300 for aws-cdk-lib) and writes `from . import ` for each one. That's what produces the 300+ eager import lines at the bottom of `aws_cdk/__init__.py`. + +**The mapping:** + +| TypeScript generator code | Generated Python output | +|---|---| +| `code.line('import abc')` | `import abc` | +| `code.line('import jsii')` | `import jsii` | +| `code.line('publication.publish()')` | `publication.publish()` | +| `code.line(\`from . import ${submodule}\`)` in a loop | `from . import aws_s3`

Opens `aws_cdk/aws_s3/__init__.py` +2. Executes it top to bottom +3. That file defines ~200 classes (Bucket, BucketPolicy, CfnBucket, CfnBucketPolicy, etc.) +4. Each class definition triggers jsii registration (telling the jsii runtime "this Python class maps to this TypeScript type") +5. Returns back to `aws_cdk/__init__.py` and moves to the next line + +This happens **for every single `from . import` line**. 300+ times. Each submodule has dozens to hundreds of classes. Total: thousands of class definitions, thousands of jsii registrations. + +**The user only needed `App`, `Stack`, and `aws_s3`. But Python loaded all 300+ submodules because the `__init__.py` told it to.** + +### Step 6: Python finally finishes loading `aws_cdk` + +After 6 seconds, Python has executed all 300+ imports. Now it returns to `app.py` and resolves the names the user asked for: `App`, `Stack`, `aws_s3`. These are now available. + +### Step 7: User code runs + +```python +app = App() # sends "create App" to Node.js +MyStack(app, "MyStack") # sends "create Stack" to Node.js +aws_s3.Bucket(self, "MyBucket") # sends "create Bucket" to Node.js +app.synth() # tells Node.js to produce CloudFormation +``` + +Each of these calls goes through the jsii runtime to Node.js, which runs the real TypeScript code and produces a CloudFormation template. + +### Step 8: Output + +The CDK CLI receives the CloudFormation template from the Python process and prints it (or deploys it). + +### Where the 6 seconds went + +| Time | What's happening | +|---|---| +| 0.0s - 0.1s | Python starts, finds `aws_cdk` | +| 0.1s - 0.5s | Executes root-level class definitions (App, Stack, etc.) | +| 0.5s - 6.0s | **Loads 300+ submodules the user never asked for** | +| 6.0s - 6.1s | User code actually runs | + +--- + +## Part 7: The Build Pipeline (Producer Side) + +This is how the Python package gets created and published: + +``` +TypeScript source code (hand-written by CDK team) + │ + ▼ + tsc + jsii compiler + │ + ▼ + .jsii assembly (JSON manifest of the entire API — ~50MB) + │ + ▼ + jsii-pacmak (code generator — THIS IS WHAT YOU'RE MODIFYING) + │ + ▼ + Python source code (generated, not hand-written) + │ + ▼ + wheel/sdist (packaged for PyPI) + │ + ▼ + pip install (what users get) +``` + +### What the .jsii assembly contains + +A machine-readable catalog of every public type: + +```json +{ + "fqn": "aws-cdk-lib.aws_s3.Bucket", + "kind": "class", + "name": "Bucket", + "initializer": { + "parameters": [ + { "name": "scope", "type": { "fqn": "constructs.Construct" } }, + { "name": "id", "type": { "primitive": "string" } } + ] + }, + "properties": [ + { "name": "bucketArn", "type": { "primitive": "string" }, "immutable": true } + ] +} +``` + +### What pacmak generates from it + +```python +class Bucket(Resource): + def __init__(self, scope: Construct, id: str) -> None: + jsii.create(self.__class__, self, [scope, id]) + + @property + def bucket_arn(self) -> str: + return jsii.get(self, "bucketArn") +``` + +The generated Python class is a **puppet**. It doesn't contain business logic. When you call `Bucket(scope, id)`, the Python code sends a message to Node.js saying "create a Bucket with these args." Node.js runs the real TypeScript implementation and sends back a reference. + +--- + +## Part 8: What We're Changing + +We're modifying the TypeScript loop in `packages/jsii-pacmak/lib/targets/python.ts` so that instead of generating: + +```python +from . import aws_s3 +from . import aws_lambda +from . import aws_ec2 +# ... 300+ more +``` + +It generates: + +```python +import importlib as _importlib + +_SUBMODULES = {"aws_s3", "aws_lambda", "aws_ec2", ...} + +def __getattr__(name): + if name in _SUBMODULES: + mod = _importlib.import_module(f".{name}", __name__) + globals()[name] = mod + return mod + raise AttributeError(f"module {__name__!r} has no attribute {name!r}") + +def __dir__(): + return [*__all__, *_SUBMODULES] +``` + +### How this changes the user's experience + +With lazy loading, the user's `cdk synth` flow becomes: + +1. Python executes `from aws_cdk import App, Stack, aws_s3` +2. Python opens `aws_cdk/__init__.py` and starts executing it +3. It defines root-level classes (`App`, `Stack`, etc.) +4. It defines `_SUBMODULES = {"aws_s3", "aws_lambda", ...}` and `__getattr__` — **no actual imports happen** +5. Python sees the user wants `aws_s3` → calls `__getattr__("aws_s3")` → imports just that one module +6. Done. **~0.2 seconds instead of 6.** + +| Time | What's happening (after fix) | +|---|---| +| 0.0s - 0.1s | Python starts, finds `aws_cdk` | +| 0.1s - 0.2s | Executes root-level class definitions + defines `__getattr__` | +| 0.2s - 0.3s | Loads `aws_s3` only (because user asked for it) | +| 0.3s - 0.4s | User code runs | + +6 seconds → 0.4 seconds. The user's code doesn't change at all. + +--- + +## Part 9: Why the Eager Imports Existed in the First Place + +The comment in the generated code says: + +```python +# Loading modules to ensure their types are registered with the jsii runtime library +``` + +When the jsii runtime receives an object from Node.js (e.g., a method returns an `iam.Role`), it needs to know which Python class corresponds to `aws-cdk-lib.aws_iam.Role`.

For `aws_cdk/__init__.py`, `__name__` is `"aws_cdk"`. + +`importlib.import_module` needs this as the second argument to know what package the relative import is relative TO.

It's a live reference — modifying it actually modifies the module's namespace. + +Source: [Python docs — globals()](https://docs.python.org/3/library/functions.html#globals) + +For a module, `globals()` is the same as the module's `__dict__`. It contains every variable, function, and class defined at the module level. + +### What this line does + +It adds the imported module to the module's namespace. After `globals()["aws_s3"] = mod`, the module now has `aws_s3` as a regular attribute. + +### Why this is "caching" + +Remember Python's lookup order: +1. Check `__dict__` (globals) +2. If not found, call `__getattr__` + +After we do `globals()[name] = mod`, the next time someone accesses `aws_cdk.aws_s3`, Python finds it in step 1 and **never calls `__getattr__` again** for that name. The lazy loading only happens once per submodule. + +### How caching worked before (in the old approach) + +In the old code with `from . import aws_s3`, Python automatically put `aws_s3` into the module's globals when the import statement executed. So it was "cached" from the start — but at the cost of loading everything upfront. + +Our approach achieves the same end state (module in globals), but defers it until first access. + +### Why not just rely on `sys.modules` caching? + +`sys.modules` caching means `importlib.import_module` won't re-execute the file. But without `globals()[name] = mod`, Python would still call `__getattr__` every single time someone accesses `aws_cdk.aws_s3` (because it's not in the module's `__dict__`). That would add overhead on every access. By putting it in globals, we make subsequent accesses as fast as if we'd done the eager import. + +--- + +## Line 13: `return mod` + +### What this does + +Returns the imported module to whoever asked for it. If the user wrote `aws_cdk.aws_s3.Bucket(...)`, Python called `__getattr__("aws_s3")`, we imported the module, cached it, and now return it.

Python relies on this: + +- `hasattr(aws_cdk, "fake")` works by calling `__getattr__("fake")` and checking if it raises `AttributeError`. If it does, `hasattr` returns `False`. If we raised a different exception (like `ValueError`), `hasattr` would crash instead of returning `False`. +- `getattr(aws_cdk, "fake", default_value)` works the same way — it catches `AttributeError` and returns the default. + +### Did the old code raise this error? + +Not explicitly — but the behavior was the same. In the old code, if you accessed `aws_cdk.totally_fake_thing`, Python would look in the module's `__dict__`, not find it, and raise `AttributeError` automatically (since there was no `__getattr__` to call). Now we have `__getattr__`, so we need to raise the error ourselves for unknown names. + +### What `{__name__!r}` means + +The `!r` is a format specifier that adds quotes around the value. `__name__` is `"aws_cdk"`, so `{__name__!r}` produces `'aws_cdk'` (with quotes).

The first line of that file is typically: + +```python +from aws_cdk import App, Stack, aws_s3 +``` + +This single line takes **~6 seconds** to execute because of how the generated `aws_cdk/__init__.py` is structured.

Every CDK command pays this 6-second tax before doing any useful work. + +The fix changes the code generator (jsii-pacmak) to emit a **lazy loading pattern** instead, so submodules are only imported when actually accessed. The user's code doesn't change at all — they just get faster imports after upgrading. + +--- + +## What is `__init__.py`? + +In Python, a directory becomes an importable **package** when it contains a file named `__init__.py`. When you write `import aws_cdk`, Python finds the `aws_cdk/` directory and executes `aws_cdk/__init__.py` top-to-bottom. Whatever names (classes, functions, variables) are defined in that file become attributes of the `aws_cdk` module. + +This is roughly analogous to a TypeScript barrel file (`index.ts`) that re-exports from submodules — except Python actually **executes** the file at import time rather than just resolving static declarations. + +**Source:** [Python docs — Packages](https://docs.python.org/3/tutorial/modules.html#packages) + +--- + +## How `from ... import ...` Works (The `from` Form) + +The `from` form of import is the most relevant to this design because it's what triggers `__getattr__`. It uses a different (more complex) process than plain `import`. + +### The Algorithm + +The Python docs define the `from` form as a two-phase process: + +> 1. Find the module specified in the `from` clause, loading and initializing it if necessary +> 2. For each of the identifiers specified in the `import` clauses: +> - Check if the imported module has an **attribute** by that name +> - If not, attempt to **import a submodule** with that name and then check the imported module again for that attribute +> - If the attribute is not found, `ImportError` is raised +> - Otherwise, a reference to that value is stored in the current namespace + +**Source:** [Python docs — The import statement](https://docs.python.org/3/reference/simple_stmts.html#the-import-statement) + +### Step-by-Step: `from aws_cdk import App, Stack, aws_s3` + +Let's trace what happens: + +**Phase 1 — Load the `from` module:** +1. Python loads `aws_cdk` (finds `aws_cdk/`, executes `aws_cdk/__init__.py`) +2. The `aws_cdk` module object is now available (but NOT bound in the caller's namespace yet) + +**Phase 2 — Resolve each name:** + +For `App`: +1. Check: does `aws_cdk` have an attribute `App`? → Yes (it's a class defined in `__init__.py`) +2. Bind `App` in the caller's namespace + +For `Stack`: +1. Check: does `aws_cdk` have an attribute `Stack`? → Yes +2. Bind `Stack` in the caller's namespace + +For `aws_s3`: +1. Check: does `aws_cdk` have an attribute `aws_s3`? + - **With eager imports:** Yes — it was loaded by `from . import aws_s3` at the bottom of `__init__.py` + - **With lazy imports:** No — it's not in `__dict__` yet, so Python calls `__getattr__("aws_s3")`, which imports it on demand +2. Bind `aws_s3` in the caller's namespace + +### The Attribute Check is Key + +The critical detail is step 2's "check if the imported module has an **attribute** by that name." This is a `getattr()` call on the module object. For modules that define `__getattr__` (PEP 562), this triggers the custom `__getattr__` function when the name isn't found in `__dict__`. + +This is exactly why our lazy loading works with `from aws_cdk import aws_s3` — Python's `from` import machinery does an attribute lookup, which triggers our `__getattr__`, which does the lazy import. + +### The Fallback: Submodule Import Attempt + +If the attribute check fails (and there's no `__getattr__`, or `__getattr__` raises `AttributeError`), Python has a **fallback**: it attempts to import a submodule with that name. This is implemented in CPython's `_handle_fromlist()` function, which is called when `__import__()` receives a non-empty `fromlist`. + +The pseudocode is roughly: + +```python +# CPython's _handle_fromlist (simplified) +def _handle_fromlist(module, fromlist, import_func): + for name in fromlist: + if not hasattr(module, name): # ← triggers __getattr__ if defined + # Fallback: try importing as a submodule + try: + import_func(f"{module.__name__}.{name}") + except ImportError: + raise ImportError(f"cannot import name '{name}' from '{module.__name__}'") + return module +``` + +**Source:** [CPython internals — `PyImport_ImportModuleLevelObject`](https://pythondev.readthedocs.io/import.html) + +### The `hasattr` → `__getattr__` Connection + +The `hasattr(module, name)` call in `_handle_fromlist` is what connects the `from` import to PEP 562. In Python, `hasattr(obj, name)` is equivalent to: + +```python +try: + getattr(obj, name) + return True +except AttributeError: + return False +``` + +So `hasattr(aws_cdk, "aws_s3")` calls `getattr(aws_cdk, "aws_s3")`, which: +1. Checks `aws_cdk.__dict__` — not found (lazy loading, not imported yet) +2. Calls `aws_cdk.__getattr__("aws_s3")` — our lazy loader imports it and returns the module +3. `hasattr` returns `True` — the fallback submodule import is never reached + +This means with our `__getattr__` in place, the fallback path is never taken. The attribute check succeeds on the first try because `__getattr__` handles it. + +### What `from . import aws_s3` Does (Relative Form) + +The statement `from . import aws_s3` inside `aws_cdk/__init__.py` is a **relative import**. The dot (`.`) means "from the current package." The process is the same as above, but the `from` clause resolves relative to the current package: + +1. The `.` resolves to the current package (`aws_cdk`) +2. Python checks if `aws_cdk` has an attribute `aws_s3` +3. If not, it attempts to import `aws_cdk.aws_s3` as a submodule +4. The submodule is loaded (its `__init__.py` is executed) and bound as an attribute on the parent + +This is the mechanism that causes the current slowness: the generated `__init__.py` has ~300 of these `from . import ` statements, and Python executes each one sequentially, loading thousands of class definitions. + +**Source:** [Python docs — The import system, §5.7 Package Relative Imports](https://docs.python.org/3/reference/import.html#package-relative-imports) + +### The `from ... import *` Case + +When the identifier list is replaced by `*`: + +```python +from aws_cdk import * +``` + +Python checks the module's `__all__` variable. If defined, it imports each name listed in `__all__`. Each name goes through the same attribute-check-then-fallback process described above.

The `cdk` command is a Node.js + program. It reads your `cdk.json`, figures out how to run your app. + +2. **Python process starts** — the CLI runs `python app.py`. Python boots up, + initializes its runtime. + +3. **`import aws_cdk`** — your app's first line loads the CDK library. Today, + this eagerly imports all ~300 service modules (S3, Lambda, EC2, etc.) even + if you only use one. **This is what we're optimizing.** + +4. **Your app runs** — Python executes your code: creating stacks, buckets, + Lambda functions, etc. Behind the scenes, every `Bucket(...)` or + `.grant_read(...)` call sends a JSON message over stdin/stdout to a child + Node.js process (the "jsii kernel") that creates the real TypeScript + object. This back-and-forth (IPC) happens for every CDK construct + operation — object creation, method calls, property access. + +5. **Templates are generated** — at the end, `app.synth()` tells the kernel + to walk the construct tree, resolve cross-references (tokens), and produce + CloudFormation templates. These JSON files (plus asset manifests and + metadata) are written to `cdk.out/` as the "cloud assembly" — everything + needed to deploy your infrastructure. + +### Hypothesis: Eager imports are a significant contributor + +We hypothesize that step 2 (importing `aws_cdk`) accounts for a meaningful +portion of the total synth time because: + +- `aws-cdk-lib` has ~300 submodules, all loaded eagerly +- Each submodule triggers file I/O, bytecode compilation, class definitions, + and jsii type registration +- This cost is paid on **every** synth, regardless of which services the app + uses +- The stability of the P90 (low variance) is consistent with a fixed startup + cost dominating + +### Profiling needed to confirm + +The telemetry does not isolate import time from synthesis time.

Backwards Compatibility Preserved + +The following import patterns continue to work: + +| Pattern | Mechanism | +|---------|-----------| +| `import aws_cdk; aws_cdk.aws_s3` | `__getattr__` triggers lazy import | +| `from aws_cdk import aws_s3` | `__getattr__` triggers lazy import | +| `import aws_cdk.aws_s3` | Python's import system handles dotted imports directly | +| `from aws_cdk import *` | `__all__` includes submodule names; triggers lazy load | +| `dir(aws_cdk)` | `__dir__` returns all public names + submodules | + +### 5.

Retries the lookup — succeeds + +This was verified with the `jsii-calc` fixture which has nested submodules +(`cdk16625.donotimport`) specifically designed to test this scenario. + +## Profiling & Benchmarking + +### Step 1: Isolate import time (before — eager loading) + +Measure how long `import aws_cdk` takes with the current eager-loading code: + +```bash +# Using Python's built-in import profiler +python3 -X importtime -c "import aws_cdk" 2> eager_import_times.log + +# Human-readable summary (top-level time is the total) +python3 -c " +import time, sys +before = len(sys.modules) +t0 = time.perf_counter() +import aws_cdk +t1 = time.perf_counter() +after = len(sys.modules) +print(f'Import time: {(t1-t0)*1000:.0f} ms') +print(f'Modules loaded: {after - before}') +" +``` + +The `-X importtime` flag produces a tree showing every import with self and +cumulative time in microseconds.

This is the standard PEP 562 caching pattern. - -3. **Assembly-loading modules excluded**: Modules with `loadAssembly=true` (the `_jsii` package) must eagerly import dependencies to initialize the jsii kernel. These are already guarded by an `assert` in `addPythonModule` and never have child submodules registered. - -4. **`import importlib` added to module header**: We add `import importlib as _importlib` to the standard imports block (only when the module has submodules). The underscore-prefixed alias avoids polluting the module namespace and is hidden by `publication.publish()`. - -5. **Submodule names remain in `__all__`**: This preserves `from aws_cdk import *` behavior. When Python processes `import *`, it accesses each name in `__all__`, which triggers `__getattr__` for submodule names, lazily loading them. - -## Components and Interfaces - -### Modified Component: `PythonModule.emit()` method - -**File**: `packages/jsii-pacmak/lib/targets/python.ts` - -The `emit()` method is the only method that changes. The modification replaces the final "Loading modules" block with the lazy loading code block. - -#### Current flow (end of `emit()`): -1. Emit `__all__` list -2. Call `publication.publish()` -3.

Assembly-loading modules continue to eagerly import dependencies. -- **`PythonModule.emitRequiredImports()`**: No changes. Cross-submodule type imports (used in type annotations) remain eager. -- **`type-name.ts`**: No changes.

The existing `PythonModule` class fields are sufficient: - -- `this.modules: PythonModule[]` — already tracks child submodules -- `this.loadAssembly: boolean` — already distinguishes assembly-loading modules -- `this.pythonName: string` — used to compute relative submodule short names - -The only new generated Python artifact is the `_SUBMODULES` set literal, which is a simple set of string constants derived from `this.modules`. - -## Correctness Properties - -*A property is a characteristic or behavior that should hold true across all valid executions of a system — essentially, a formal statement about what the system should do. Properties serve as the bridge between human-readable specifications and machine-verifiable correctness guarantees.* - -### Property 1: Submodule set correctness - -*For any* `PythonModule` with one or more child submodules, the generated `_SUBMODULES` set SHALL contain exactly the sorted short names of all direct child submodules, and the generated code SHALL NOT contain any eager `from . import ` statements for those submodules. - -**Validates: Requirements 1.1, 8.1** - -### Property 2: __all__ includes submodule names - -*For any* `PythonModule` with one or more child submodules, the generated `__all__` list SHALL include the short name of every direct child submodule. - -**Validates: Requirements 2.2** - -### Property 3: Assembly-loading modules are excluded from lazy loading - -*For any* `PythonModule` with `loadAssembly` set to true, the generated code SHALL NOT contain `_SUBMODULES`, `__getattr__`, or `__dir__` definitions, and SHALL continue to emit eager dependency imports. - -**Validates: Requirements 6.1** - -### Property 4: Code generation determinism (idempotence) - -*For any* jsii assembly, generating Python code twice from the same assembly SHALL produce byte-for-byte identical output. - -**Validates: Requirements 8.2** - -## Error Handling - -### AttributeError for unknown attributes - -The generated `__getattr__` raises `AttributeError` with a descriptive message when the requested name is not in `_SUBMODULES`. This is the standard Python protocol for missing attributes and ensures that `hasattr()`, `getattr(mod, name, default)`, and try/except patterns work correctly. - -```python -raise AttributeError(f"module {__name__!r} has no attribute {name!r}") -``` - -### Import errors propagate naturally - -The generated `__getattr__` does NOT wrap `importlib.import_module` in a try/except. If a submodule fails to import (e.g., missing dependency, syntax error, jsii type registration failure), the original `ImportError` or other exception propagates to the caller. This matches the behavior of eager `from . import` statements and satisfies Requirement 3.3. - -### No silent fallback - -There is no fallback mechanism. If a submodule listed in `_SUBMODULES` cannot be imported, the error is surfaced immediately. This is intentional — silent failures would mask real problems in the generated packages. - -## Testing Strategy - -### Snapshot Tests (Primary validation) - -The existing snapshot test infrastructure (`packages/jsii-pacmak/test/generated-code/target-python.test.ts`) is the primary validation mechanism. It generates Python code for all test fixture packages (`@scope/jsii-calc-base-of-base`, `@scope/jsii-calc-base`, `@scope/jsii-calc-lib`, `jsii-calc`) and compares against stored snapshots. - -**After this change:** -- All snapshots will be updated to reflect the new lazy loading pattern -- The mypy check that runs on generated code will validate type correctness of `__getattr__` and `__dir__` -- The pyright check (`python-pyright.test.ts`) will validate type checker compatibility - -### Property-Based Tests - -Property-based tests will validate the correctness properties using `fast-check` (already available in the jsii monorepo's test infrastructure via Jest). - -Each property test will: -- Generate random inputs (submodule name lists, module configurations) -- Invoke the code generation logic -- Assert the property holds across 100+ iterations - -**Configuration:** -- Library: `fast-check` -- Minimum iterations: 100 per property -- Each test tagged with: `Feature: python-lazy-imports, Property {N}: {description}` - -**Property tests to implement:** - -1. **Property 1 test**: Generate random arrays of valid Python identifier strings as submodule names. Create a `PythonModule` with those submodules, run `emit()`, and verify: - - The output contains a `_SUBMODULES` set with exactly those names, sorted - - The output does NOT contain `from . import ` for any of those names - -2. **Property 2 test**: Generate random arrays of submodule names. Run `emit()` and verify every submodule short name appears in the `__all__` list. - -3. **Property 3 test**: Generate module configurations with `loadAssembly=true`. Run `emit()` and verify the output contains none of: `_SUBMODULES`, `def __getattr__`, `def __dir__`. - -4. **Property 4 test**: For a given assembly fixture, run code generation twice and verify the outputs are identical. (This can also be validated as a simpler determinism check by running emit twice on the same PythonModule configuration.) - -### Unit Tests (Example-based) - -Example-based unit tests for specific scenarios: - -- Module with submodules generates `__getattr__` with correct `importlib.import_module(f".{name}", __name__)` pattern -- Module with submodules generates `__dir__` returning `[*__all__, *_SUBMODULES]` -- Module with zero submodules generates no lazy loading code -- `__getattr__` raises `AttributeError` for unknown names (code structure check) -- `publication.publish()` appears before the lazy loading block -- `import importlib as _importlib` is added to imports when submodules exist -- `import importlib as _importlib` is NOT added when no submodules exist -- The `from ..._jsii import *` statement is preserved in non-assembly modules - -### Integration Tests (Existing) - -The existing integration test suite (compliance tests, runtime tests) validates end-to-end behavior: - -- `from aws_cdk import aws_s3` works -- `import aws_cdk.aws_s3` works -- `from aws_cdk import *` loads all submodules -- jsii type registration works on first access -- Type marshaling and cross-language callbacks function correctly - -These tests run against the generated packages and exercise the actual lazy loading at runtime. - - - -## Implementation Notes - -### Note 1: Dotted imports bypass `__getattr__` - -`import aws_cdk.aws_s3` (the dotted form) does NOT go through `__getattr__`. Python's import system resolves subpackages directly by looking for the directory on disk. This means the dotted import pattern works without any special handling from our side. No action needed — just be aware that `__getattr__` only fires for attribute access (`aws_cdk.aws_s3`) and `from aws_cdk import aws_s3`, not for `import aws_cdk.aws_s3`. - -### Note 2: Cross-module type deserialization (verify during implementation) - -If a method returns a type from a module the user never explicitly imported (e.g., an `aws_s3.Bucket` method returns an `aws_iam.Role`), the jsii runtime needs to deserialize that type. Currently this works because `aws_iam` was eagerly loaded. With lazy loading, `aws_iam` might not be loaded yet. - -The jsii Python runtime resolves types by FQN and should trigger imports as needed, so this is expected to work. However, add a test case during implementation that exercises this scenario: call a method that returns a type from an unimported submodule and verify it deserializes correctly. diff --git a/.kiro/specs/python-lazy-imports/requirements.md b/.kiro/specs/python-lazy-imports/requirements.md deleted file mode 100644 index 2def29721f..0000000000 --- a/.kiro/specs/python-lazy-imports/requirements.md +++ /dev/null @@ -1,100 +0,0 @@ -# Requirements Document - -## Introduction - -This feature replaces eager submodule imports in jsii-pacmak's Python code generator with lazy loading using Python PEP 562 module-level `__getattr__`.

THE Code_Generator SHALL continue to emit type stub information (via `__all__` and existing type annotations) so that static analysis tools can resolve Submodule names. - -### Requirement 6: Preserve Assembly-Loading Module Behavior - -**User Story:** As a jsii-pacmak maintainer, I want the root assembly-loading module (the `_jsii` package loader) to remain unchanged, so that jsii assembly initialization is not affected by lazy loading. - -#### Acceptance Criteria - -1. WHEN a PythonModule has `loadAssembly` set to true, THE Code_Generator SHALL NOT apply lazy loading to that module and SHALL continue to emit eager dependency imports. -2. WHEN a PythonModule does not load an assembly, THE Code_Generator SHALL apply lazy loading to its child Submodule imports while preserving the eager `from ..._jsii import *` statement that loads the jsii assembly bindings. - -### Requirement 7: Generate Correct Relative Imports in Lazy Loader - -**User Story:** As a jsii-pacmak maintainer, I want the lazy loader to use relative imports consistent with the existing code generation strategy, so that the generated packages work in both pip-installed and bazel-managed environments. - -#### Acceptance Criteria - -1.

Bind `aws_s3` in the caller's namespace - -### The Attribute Check is Key - -The critical detail is step 2's "check if the imported module has an **attribute** by that name." This is a `getattr()` call on the module object. For modules that define `__getattr__` (PEP 562), this triggers the custom `__getattr__` function when the name isn't found in `__dict__`. - -This is exactly why our lazy loading works with `from aws_cdk import aws_s3` — Python's `from` import machinery does an attribute lookup, which triggers our `__getattr__`, which does the lazy import. - -### The Fallback: Submodule Import Attempt - -If the attribute check fails (and there's no `__getattr__`, or `__getattr__` raises `AttributeError`), Python has a **fallback**: it attempts to import a submodule with that name. This is implemented in CPython's `_handle_fromlist()` function, which is called when `__import__()` receives a non-empty `fromlist`. - -The pseudocode is roughly: - -```python -# CPython's _handle_fromlist (simplified) -def _handle_fromlist(module, fromlist, import_func): - for name in fromlist: - if not hasattr(module, name): # ← triggers __getattr__ if defined - # Fallback: try importing as a submodule - try: - import_func(f"{module.__name__}.{name}") - except ImportError: - raise ImportError(f"cannot import name '{name}' from '{module.__name__}'") - return module -``` - -**Source:** [CPython internals — `PyImport_ImportModuleLevelObject`](https://pythondev.readthedocs.io/import.html) - -### The `hasattr` → `__getattr__` Connection - -The `hasattr(module, name)` call in `_handle_fromlist` is what connects the `from` import to PEP 562. In Python, `hasattr(obj, name)` is equivalent to: - -```python -try: - getattr(obj, name) - return True -except AttributeError: - return False -``` - -So `hasattr(aws_cdk, "aws_s3")` calls `getattr(aws_cdk, "aws_s3")`, which: -1. Checks `aws_cdk.__dict__` — not found (lazy loading, not imported yet) -2. Calls `aws_cdk.__getattr__("aws_s3")` — our lazy loader imports it and returns the module -3. `hasattr` returns `True` — the fallback submodule import is never reached - -This means with our `__getattr__` in place, the fallback path is never taken. The attribute check succeeds on the first try because `__getattr__` handles it. - -### What `from . import aws_s3` Does (Relative Form) - -The statement `from . import aws_s3` inside `aws_cdk/__init__.py` is a **relative import**. The dot (`.`) means "from the current package." The process is the same as above, but the `from` clause resolves relative to the current package: - -1. The `.` resolves to the current package (`aws_cdk`) -2. Python checks if `aws_cdk` has an attribute `aws_s3` -3. If not, it attempts to import `aws_cdk.aws_s3` as a submodule -4. The submodule is loaded (its `__init__.py` is executed) and bound as an attribute on the parent - -This is the mechanism that causes the current slowness: the generated `__init__.py` has ~300 of these `from . import ` statements, and Python executes each one sequentially, loading thousands of class definitions. - -**Source:** [Python docs — The import system, §5.7 Package Relative Imports](https://docs.python.org/3/reference/import.html#package-relative-imports) - -### The `from ... import *` Case - -When the identifier list is replaced by `*`: - -```python -from aws_cdk import * -``` - -Python checks the module's `__all__` variable. If defined, it imports each name listed in `__all__`. Each name goes through the same attribute-check-then-fallback process described above. Since our `__all__` includes submodule names, and our `__getattr__` handles them, `from aws_cdk import *` lazily loads all submodules (which is the same end result as eager loading, just triggered differently). - -**Source:** [Python docs — The import statement](https://docs.python.org/3/reference/simple_stmts.html#the-import-statement) - -### Bytecode-Level: What the Compiler Generates - -At the bytecode level, `from aws_cdk import aws_s3` compiles to two instructions: - -``` -IMPORT_NAME aws_cdk (with fromlist=('aws_s3',)) -IMPORT_FROM aws_s3 (getattr on the module) -``` - -The `IMPORT_NAME` instruction calls `__import__("aws_cdk", fromlist=("aws_s3",))`. The non-empty `fromlist` tells CPython to call `_handle_fromlist()` after loading the module, which does the attribute lookup. The `IMPORT_FROM` instruction then does a final `getattr()` on the loaded module to get the specific name. - -**Source:** [CPython internals — IMPORT_NAME bytecode](https://pythondev.readthedocs.io/import.html) - -### Summary Table: `from` Import Variants - -| Statement | What Python does | Triggers `__getattr__`? | -|---|---|---| -| `from aws_cdk import App` | Load `aws_cdk`, get attribute `App` | Only if `App` not in `__dict__` | -| `from aws_cdk import aws_s3` | Load `aws_cdk`, get attribute `aws_s3` | Yes (with lazy loading) | -| `from . import aws_s3` (inside `__init__.py`) | Resolve `.` to current package, get attribute `aws_s3` | Yes (with lazy loading) | -| `from aws_cdk import *` | Load `aws_cdk`, get each name in `__all__` | Yes, for submodule names | -| `from aws_cdk.aws_s3 import Bucket` | Load `aws_cdk`, load `aws_cdk.aws_s3`, get attribute `Bucket` | No — dotted `from` clause uses import system directly | - ---- - -## What is `__getattr__` on a Module? (PEP 562) - -Since Python 3.7, you can define a function called `__getattr__` at the **module level** (not inside a class). Python calls this function when someone accesses an attribute on the module that doesn't already exist in the module's namespace. - -The lookup order is: -1. Check the module's `__dict__` (its global namespace — all variables, functions, classes defined in the file) -2. If not found, call `__getattr__(name)` if it exists -3. If `__getattr__` raises `AttributeError`, Python raises `AttributeError` to the caller - -This is the hook that enables lazy loading: instead of importing all submodules upfront, we define `__getattr__` to import them on-demand when first accessed. - -**TypeScript analogy:** Think of it like a JavaScript `Proxy` with a `get` trap on the module object — it intercepts property access for names that don't exist yet. - -**Source:** [Python docs — Customizing module attribute access](https://docs.python.org/3/reference/datamodel.html#customizing-module-attribute-access) -**Source:** [PEP 562 – Module `__getattr__` and `__dir__`](https://peps.python.org/pep-0562/) - ---- - -## What is `importlib.import_module()`? - -`importlib.import_module(name, package=None)` is the programmatic way to import a module in Python. It accepts the module name as a string and returns the module object. - -- **Absolute import:** `importlib.import_module("aws_cdk.aws_s3")` — imports by full path -- **Relative import:** `importlib.import_module(".aws_s3", "aws_cdk")` — imports `.aws_s3` relative to the `aws_cdk` package - -We use the relative form because it mirrors the semantics of `from . import aws_s3` and works correctly regardless of how the package is installed (pip, editable install, bazel, etc.). - -The key difference from a regular `import` statement is that the module name can be a **variable** — which is what makes dynamic/lazy importing possible. - -**Source:** [Python docs — `importlib.import_module()`](https://docs.python.org/3/library/importlib.html#importlib.import_module) - ---- - -## What is `globals()`? - -`globals()` returns a dictionary representing the current module's global namespace. It is a **live reference** — modifying it actually modifies the module's namespace. - -When we write `globals()[name] = mod` inside `__getattr__`, we are adding the imported module to the module's namespace. On the next access, Python finds it in step 1 of the lookup order (checking `__dict__`) and never calls `__getattr__` again for that name. This is the caching mechanism. - -**TypeScript analogy:** It's like assigning to `module.exports[name]` at runtime — the name becomes a permanent property of the module. - -**Source:** [Python docs — `globals()`](https://docs.python.org/3/library/functions.html#globals) - ---- - -## What is `__dir__` on a Module? - -When someone calls `dir(module)` in Python (used by IDEs for tab-completion and introspection), Python calls the module's `__dir__()` function if defined. Without it, `dir()` only shows names currently in the module's `__dict__` — which would exclude lazily-loaded submodules that haven't been accessed yet. - -By defining `__dir__` to return `[*__all__, *_SUBMODULES]`, we ensure that IDE autocomplete and interactive exploration still show all available submodules even before they're loaded. - -**Source:** [Python docs — Customizing module attribute access](https://docs.python.org/3/reference/datamodel.html#customizing-module-attribute-access) - ---- - -## What is `__all__`? - -`__all__` is a module-level list of strings that defines which names are exported when someone writes `from module import *`. It serves as the module's public API declaration. - -In the generated code, `__all__` includes both the classes defined in the module (like `App`, `Stack`) and the submodule names (like `aws_s3`, `aws_lambda`). When Python processes `from aws_cdk import *`, it accesses each name in `__all__`, which triggers `__getattr__` for any submodule names not yet loaded. - -**Source:** [Python docs — The import system, §5.4.2 Importing * from a package](https://docs.python.org/3/reference/import.html#importing-from-a-package) - ---- - -## What is `publication.publish()`? - -[`publication`](https://pypi.org/project/publication/) is a third-party Python package used in jsii-generated code. Calling `publication.publish()` replaces the current module object in `sys.modules` with a new one that only exposes names listed in `__all__`. This hides internal/private names (those with underscore prefixes like `_importlib`, `_SUBMODULES`) from `dir()` and tab-completion. - -**Important for this design:** Because `publication.publish()` replaces the module object, any `__getattr__` or `__dir__` defined on the original module won't be visible on the replacement. That's why the generated code uses `setattr(sys.modules[__name__], "__getattr__", __getattr__)` to explicitly install these functions on the public module after defining them. - -**Source:** [PyPI — publication](https://pypi.org/project/publication/) - ---- - -## What is `typing.TYPE_CHECKING`? - -`typing.TYPE_CHECKING` is a special constant in Python's `typing` module. It is `False` at runtime but assumed to be `True` by static type checkers (pyright, mypy). This allows you to write imports that only exist for the benefit of type checkers without incurring any runtime cost: - -```python -import typing - -if typing.TYPE_CHECKING: - from . import aws_s3 as aws_s3 # only visible to type checkers -``` - -We use this pattern so that pyright/mypy can "see" the submodule names statically (for autocomplete and type checking) while preserving lazy loading at runtime. - -**Source:** [Python docs — `typing.TYPE_CHECKING`](https://docs.python.org/3/library/typing.html#typing.TYPE_CHECKING) -**Source:** [PEP 781 – Make TYPE_CHECKING a built-in constant](https://peps.python.org/pep-0781/) (background on its purpose) - ---- - -## What is `sys.modules`? - -`sys.modules` is a dictionary that Python uses as a **cache** for all imported modules. The keys are module names (strings) and the values are module objects. When you import a module, Python first checks `sys.modules` — if the module is already there, it returns the cached version without re-executing the file. - -This is relevant because: -1. `publication.publish()` replaces the module object in `sys.modules` (see above) -2. `importlib.import_module()` respects `sys.modules` caching — calling it twice for the same module doesn't re-execute the file - -**Source:** [Python docs — The import system, §5.3.1 The module cache](https://docs.python.org/3/reference/import.html#the-module-cache) - ---- - -## How `import aws_cdk.aws_s3` (Dotted Import) Works - -When you write a dotted import like `import foo.bar.baz`, Python performs a **chain of imports** — it imports each component left-to-right: - -1. Import `foo` (find `foo/`, execute `foo/__init__.py`) -2. Import `foo.bar` (find `foo/bar/`, execute `foo/bar/__init__.py`) -3. Import `foo.bar.baz` (find `foo/bar/baz/`, execute `foo/bar/baz/__init__.py`) - -After all components are loaded, Python binds only the **top-level name** (`foo`) in the local namespace. You access the rest via attribute access on that name: - -```python -import foo.bar.baz # foo, foo.bar, and foo.bar.baz are all imported - # only 'foo' is bound in local namespace -foo.bar.baz.something() # access via the chain -``` - -The Python docs describe this explicitly: - -> *"If the module being imported is not a top level module, then the name of the top level package that contains the module is bound in the local namespace as a reference to the top level package. The imported module must be accessed using its full qualified name rather than directly."* - -**Source:** [Python docs — The import statement](https://docs.python.org/3/reference/simple_stmts.html#the-import-statement) - -### The Submodule Binding Rule - -A critical invariant of Python's import system: **when a submodule is loaded, a binding is placed in the parent module's namespace pointing to the submodule object.** The docs state: - -> *"When a submodule is loaded using any mechanism (e.g. importlib APIs, the import or import-from statements, or built-in `__import__()`), a binding is placed in the parent module's namespace to the submodule object."* - -So after `import aws_cdk.aws_s3`: -- `sys.modules['aws_cdk']` exists (the parent) -- `sys.modules['aws_cdk.aws_s3']` exists (the submodule) -- `aws_cdk.aws_s3` is set as an attribute on the `aws_cdk` module object - -**Source:** [Python docs — The import system, §5.4.2 Submodules](https://docs.python.org/3/reference/import.html#submodules) - -### Why Dotted Imports Bypass `__getattr__` - -The dotted import (`import aws_cdk.aws_s3`) does **not** go through `__getattr__`. Python's import machinery resolves the subpackage directly — it looks for the `aws_s3/` directory on disk, executes its `__init__.py`, and places the binding on the parent module. This is handled by the import system itself, not by attribute access on the module object. - -`__getattr__` only fires for **attribute access** on an already-imported module: -- `aws_cdk.aws_s3` (attribute access after `import aws_cdk`) → triggers `__getattr__("aws_s3")` -- `from aws_cdk import aws_s3` → Python checks the module for the attribute `aws_s3`, which triggers `__getattr__("aws_s3")` - -It does **not** fire for: -- `import aws_cdk.aws_s3` → Python's import system resolves this directly via filesystem lookup - -### How `from aws_cdk import aws_s3` Works - -The `from ... import` form uses a different process than plain `import`. The Python docs describe it as: - -1. Find the module specified in the `from` clause, loading and initializing it if necessary -2. For each identifier in the `import` clause: - - Check if the imported module has an attribute by that name - - If not, attempt to import a submodule with that name, then check again - - If still not found, raise `ImportError` - -So `from aws_cdk import aws_s3` first loads `aws_cdk`, then looks for `aws_s3` as an attribute. With lazy loading, `aws_s3` isn't in the namespace yet, so Python calls `__getattr__("aws_s3")`, which triggers the lazy import. - -**Source:** [Python docs — The import statement](https://docs.python.org/3/reference/simple_stmts.html#the-import-statement) - -### Why This Matters for Our Design - -Because dotted imports bypass `__getattr__` entirely, our lazy loading code doesn't need to handle them — they "just work" via Python's built-in import machinery. The three common import patterns all work correctly: - -| Pattern | Mechanism | Goes through `__getattr__`? | -|---|---|---| -| `import aws_cdk.aws_s3` | Python import system resolves directly | No | -| `from aws_cdk import aws_s3` | Attribute lookup on `aws_cdk` module | Yes | -| `import aws_cdk; aws_cdk.aws_s3` | Attribute access on module object | Yes | - -**Source:** [Python docs — The import system, §5.4.2 Submodules](https://docs.python.org/3/reference/import.html#submodules) - ---- - -## Summary: TypeScript ↔ Python Analogy Table - -| Python Concept | TypeScript/JS Equivalent | -|---|---| -| `__init__.py` | `index.ts` barrel file | -| `from . import aws_s3` | `export * from './aws_s3'` (but executes at runtime) | -| `__getattr__` on module | `Proxy` with `get` trap on module exports | -| `importlib.import_module()` | Dynamic `import()` / `require()` | -| `globals()[name] = mod` | `module.exports[name] = mod` | -| `__all__` | Explicit `export` declarations | -| `sys.modules` | Node.js `require.cache` | -| `typing.TYPE_CHECKING` | TypeScript's type-only imports (`import type`) | -| `publication.publish()` | No direct equivalent — imagine a post-processing step that strips non-exported names from the module | diff --git a/docs/benchmarking-lazy-imports.md b/docs/benchmarking-lazy-imports.md deleted file mode 100644 index 1070c8ce62..0000000000 --- a/docs/benchmarking-lazy-imports.md +++ /dev/null @@ -1,175 +0,0 @@ -# Benchmarking Lazy Imports Against aws-cdk-lib - -## Prerequisites - -- This jsii repo checked out on the lazy-imports branch -- Node.js and yarn installed -- Python 3.10+ installed -- A CDK Python project with a venv (for running the benchmark) - -## Step 1: Measure the baseline (eager imports) - -**Run from:** your CDK Python project directory (e.g., `~/cdk-python-project`) - -```bash -source .venv/bin/activate - -python3 -c " -import time, sys -before = len(sys.modules) -t0 = time.perf_counter() -import aws_cdk -t1 = time.perf_counter() -after = len(sys.modules) -print(f'Import time: {(t1-t0)*1000:.0f} ms') -print(f'Modules loaded: {after - before}') -" -``` - -Record the numbers.

Not suitable for hot paths. -2. **No distributed GC** — Object references leak if `del` isn't called (and most runtimes don't call it). -3. **Single-threaded** — No thread safety in runtime libraries. -4. **Async is experimental** — Event loop blocking can cause deadlocks. -5. **Type unions** — Result in `Object`/`any` in statically typed languages. Avoid when possible. -6. **No STDIN** — jsii libraries cannot read from STDIN (nothing connected to kernel's FD#0). -7. **Struct vs Interface naming** — The `I` prefix convention is mandatory and semantic. -8. **No method overloads** — TypeScript overloads are not supported in the jsii type system. -9. **Liskov substitution** — Overridden methods must have identical signatures (no covariant returns). -10. **Collections are copied** — Arrays and maps are passed by-value across the boundary every time. - ---- - -## 24.

This covers everything you should understand -> before (or while) diving into the jsii codebase. Organized from foundational → advanced. - ---- - -## 1. TypeScript & JavaScript Fundamentals - -jsii is built on TypeScript and compiles to JavaScript. You need solid understanding of both. - -### TypeScript You Must Know - -- **The type system** — interfaces, classes, generics, union types, intersection types, type guards -- **Declaration files** (`.d.ts`) — what they are, how they're generated, how they describe APIs -- **The `tsconfig.json`** — compiler options, `strict` mode, module resolution -- **The TypeScript Compiler API** — jsii wraps the TS compiler programmatically. Understand: - - `ts.Program`, `ts.SourceFile`, `ts.TypeChecker` - - How the compiler resolves types, symbols, and declarations - - AST (Abstract Syntax Tree) traversal -- **Module systems** — CommonJS (`require`/`module.exports`) vs ESM (`import`/`export`) -- **Decorators** — used in some runtime libraries (Python's `@jsii.implements`) -- **`readonly` vs mutable** — critical for struct vs interface distinction in jsii - -### JavaScript You Must Know - -- **Prototypal inheritance** — how classes actually work at runtime -- **`this` binding** — how `this` behaves in different contexts (arrow functions, methods, constructors) -- **JSON serialization** — `JSON.stringify`/`JSON.parse`, what's serializable, what's not -- **Node.js streams** — STDIN, STDOUT, STDERR, piping, buffering -- **Node.js child processes** — `child_process.spawn`, IPC, file descriptors -- **npm packages** — `package.json` structure, `main`/`types` fields, tarballs, publishing -- **The event loop** — microtasks, macrotasks, how `async`/`await` interacts with the loop - -### Resources - -- [TypeScript Handbook](https://www.typescriptlang.org/docs/handbook/intro.html) -- [TypeScript Compiler API docs](https://github.com/microsoft/TypeScript/wiki/Using-the-Compiler-API) -- [Node.js Child Processes](https://nodejs.org/api/child_process.html) -- [Node.js Streams](https://nodejs.org/api/stream.html) - ---- - -## 2. Object-Oriented Programming Concepts - -jsii maps TypeScript's OOP model to other languages. You need to understand OOP across paradigms. - -### Core Concepts - -- **Classes** — constructors, methods, properties, static members, abstract classes -- **Interfaces** — behavioral contracts vs data shapes (jsii distinguishes these) -- **Inheritance** — single inheritance (classes), multiple inheritance (interfaces) -- **Polymorphism** — method overriding, virtual dispatch, Liskov Substitution Principle -- **Encapsulation** — public/protected/private visibility -- **Composition vs inheritance** — why jsii structs exist (composition pattern) - -### Cross-Language OOP Differences You Should Know - -| Concept | TypeScript | Python | Java | C# | Go | -|---------|-----------|--------|------|----|----| -| Multiple inheritance | Interfaces only | Full (classes + mixins) | Interfaces only | Interfaces only | Embedding (no inheritance) | -| Method overloading | Not in jsii | Duck typing | Supported | Supported | Not supported | -| Properties | First-class | `@property` decorator | Getters/setters | First-class | Exported fields | -| Enums | String/number values | `enum.Enum` | Full classes | Value types | `iota` constants | -| Null safety | `undefined`/`null` | `None` | `null` | `null`/nullable | `nil`/zero values | -| Generics | Full | Type hints (PEP 484) | Type erasure | Reified | Since 1.18 | -| Structs (data classes) | Interfaces (no `I` prefix) | `@dataclass` or plain | Records/POJOs | Records/structs | Structs | - -### The Liskov Substitution Principle (LSP) - -jsii strictly enforces LSP: if you override a method, the signature must be **identical** to the parent's. No covariant -returns, no contravariant parameters. This is because not all target languages support these features. - -### Resources - -- [Liskov Substitution Principle](https://en.wikipedia.org/wiki/Liskov_substitution_principle) -- [SOLID Principles](https://en.wikipedia.org/wiki/SOLID) - ---- - -## 3. Inter-Process Communication (IPC) - -jsii's runtime is fundamentally an IPC system. The host process talks to a node child process. - -### What You Need to Know - -- **Process spawning** — how one process creates another (`fork`, `spawn`, `exec`) -- **Pipes** — STDIN (fd 0), STDOUT (fd 1), STDERR (fd 2), and custom file descriptors (fd 3+) -- **JSON-RPC-like protocols** — request/response over streams (jsii uses a custom protocol, not JSON-RPC, but the concept is similar) -- **Buffering and framing** — how to delimit messages in a byte stream (jsii uses newline-delimited JSON) -- **Blocking vs non-blocking I/O** — why the kernel can deadlock if async isn't handled carefully -- **Process lifecycle** — startup, communication, graceful shutdown - -### jsii-Specific IPC Details - -- Host sends JSON requests to kernel's STDIN -- Kernel sends JSON responses on STDOUT -- Console output is encoded on STDERR (base64-wrapped JSON) -- The kernel uses a **dual-process** setup (Wrapper + Core) because Java/C# can't open extra file descriptors on child processes -- FD#3 is used for the actual protocol between Wrapper and Core - -### Resources - -- [Unix File Descriptors](https://en.wikipedia.org/wiki/File_descriptor) -- [Node.js child_process.spawn](https://nodejs.org/api/child_process.html#child_processspawncommand-args-options) -- [Newline-delimited JSON](http://ndjson.org/) - ---- - -## 4. JSON & Serialization - -Everything crossing the jsii boundary is serialized as JSON. You need to understand serialization deeply. - -### What You Need to Know - -- **JSON data types** — string, number, boolean, null, array, object (and what's NOT representable: Date, undefined, functions, circular refs) -- **Custom serialization** — how jsii wraps non-JSON types with sentinel keys (`$jsii.date`, `$jsii.enum`, `$jsii.byref`, `$jsii.struct`, `$jsii.map`) -- **By-value vs by-reference** — primitives and structs are copied; class instances are referenced -- **Type discrimination** — how the kernel knows what type a value is when the declared type is `any` -- **Schema validation** — how `@jsii/spec` validates assembly documents (JSON Schema) - -### The jsii Serialization Wrappers - -```json -{"$jsii.date": "2020-01-20T14:04:00.000Z"} // Date -{"$jsii.enum": "module.MyEnum/VALUE"} // Enum entry -{"$jsii.map": {"key": "value"}} // Map/dictionary -{"$jsii.struct": {"fqn": "module.Opts", "data": {}}} // Struct (by-value) -{"$jsii.byref": "module.MyClass@42"} // Object reference -``` - -### Resources - -- [JSON specification](https://www.json.org/json-en.html) -- [ISO 8601 Date format](https://en.wikipedia.org/wiki/ISO_8601) - ---- - -## 5.

Go and Java have higher -P90s but much wider variance (likely due to JVM/compiler startup costs that -vary by project size). - -### What `cdk synth` includes - -The P90 number captures the full synthesis pipeline: - -1. **CDK CLI startup** — you type `cdk synth`. The `cdk` command is a Node.js - program. It reads your `cdk.json`, figures out how to run your app. - -2. **Python process starts** — the CLI runs `python app.py`. Python boots up, - initializes its runtime. - -3. **`import aws_cdk`** — your app's first line loads the CDK library. Today, - this eagerly imports all ~300 service modules (S3, Lambda, EC2, etc.) even - if you only use one. **This is what we're optimizing.** - -4. **Your app runs** — Python executes your code: creating stacks, buckets, - Lambda functions, etc. Behind the scenes, every `Bucket(...)` or - `.grant_read(...)` call sends a JSON message over stdin/stdout to a child - Node.js process (the "jsii kernel") that creates the real TypeScript - object. This back-and-forth (IPC) happens for every CDK construct - operation — object creation, method calls, property access. - -5. **Templates are generated** — at the end, `app.synth()` tells the kernel - to walk the construct tree, resolve cross-references (tokens), and produce - CloudFormation templates. These JSON files (plus asset manifests and - metadata) are written to `cdk.out/` as the "cloud assembly" — everything - needed to deploy your infrastructure. - -### Hypothesis: Eager imports are a significant contributor - -We hypothesize that step 2 (importing `aws_cdk`) accounts for a meaningful -portion of the total synth time because: - -- `aws-cdk-lib` has ~300 submodules, all loaded eagerly -- Each submodule triggers file I/O, bytecode compilation, class definitions, - and jsii type registration -- This cost is paid on **every** synth, regardless of which services the app - uses -- The stability of the P90 (low variance) is consistent with a fixed startup - cost dominating - -### Profiling needed to confirm - -The telemetry does not isolate import time from synthesis time. The following -profiling steps are needed to quantify the exact contribution: - -### Baseline measurement (eager loading, aws-cdk-lib 2.211.0) - -Measured on a development machine with `aws-cdk-lib` 2.211.0 installed: - -``` -Import time: 3236 ms -Modules loaded: 896 -``` - -A minimal CDK app (one S3 bucket) shows the phase breakdown: - -``` ---- Timing Breakdown --- -Imports: 3236 ms (93.4%) -App construction: 149 ms (4.3%) -Synthesis: 80 ms (2.3%) -Total: 3465 ms (100%) -``` - -**93.4% of the total time for a minimal app is spent on imports.** - -### Import cost is fixed, not proportional - -The ~3.2s import cost is constant regardless of app size — it's the cost of -eagerly loading all ~300 submodules. What scales with app complexity is the -construction + synthesis time: - -| App complexity | Import | Construction + Synth | Import % | -|---------------|--------|---------------------|----------| -| Tiny (1 bucket) | ~3.2s | ~0.2s | 93% | -| Small (10 constructs) | ~3.2s | ~5s | 39% | -| Medium (100 constructs) | ~3.2s | ~30s | 10% | -| Large (P90 telemetry) | ~3.2s | ~69s | 4.4% | - -For the telemetry P90 of ~72s, imports account for ~4.4% of total time. But -this is a **fixed 3.2s tax on every single run** — every `cdk synth`, every -`cdk deploy`, every test execution, every Lambda cold start. - -### Why this matters despite the small percentage for large apps - -- **Developer iteration speed** — developers run `cdk synth` many times per - hour. Saving 3.2s per run adds up. -- **Lambda cold starts** — 3.2s of cold start time is significant for - user-facing services. -- **Small apps are disproportionately affected** — a "hello world" CDK app - shouldn't take 3.5s to synthesize. -- **It's free to fix** — lazy loading eliminates this cost with no behavioral - change for users. - -## What Was Built - -### Code Generator Changes (`packages/jsii-pacmak/lib/targets/python.ts`) - -The `PythonModule.emit()` method now generates: - -1. **`_SUBMODULES` set** — sorted list of child submodule short names -2. **`__getattr__`** — imports submodule on first access via - `importlib.import_module`, caches in `globals()` -3. **`__dir__`** — returns `[*__all__, *_SUBMODULES]` for discoverability -4. **`typing.TYPE_CHECKING` block** — explicit imports visible only to static - analyzers (pyright/mypy) -5. **`setattr` installation** — installs `__getattr__`/`__dir__` on the public - module after `publication.publish()` replaces the module object - -Modules with zero submodules are unchanged. - -### Runtime Changes (`packages/@jsii/python-runtime/`) - -1. **On-demand type resolution** (`_reference_map.py`) — when the jsii kernel - returns a type from an unloaded submodule, the runtime imports the - containing module on demand so type registration occurs as a side effect. -2. **Assembly-to-module mapping** (`_runtime.py`) — `JSIIAssembly.load()` - registers the assembly name → Python root module mapping so the runtime - knows where to find unloaded types. - -## Proof Points - -### 1. Generated Code Structure Is Correct - -The `lazy-imports.test.ts` test suite verifies: - -- `_SUBMODULES` set is emitted with correct, sorted entries -- `__getattr__` uses `importlib.import_module` with relative path -- `__getattr__` caches in `globals()` and raises `AttributeError` for unknowns -- `__dir__` returns union of `__all__` and `_SUBMODULES` -- No eager `from . import` statements exist outside `TYPE_CHECKING` -- `TYPE_CHECKING` block contains explicit re-exports (`from . import x as x`) -- Modules with zero submodules have no lazy loading code -- `publication.publish()` appears before the lazy loading block -- Submodule names are included in `__all__` - -### 2. Static Type Checkers Pass - -- **pyright** — the `python-pyright.test.ts` test generates all fixture - packages and runs pyright with `pythonVersion = "3.8"`. Zero errors. -- **mypy** — the `harness.ts` test runs mypy against all generated Python - code. Zero errors. - -### 3. Snapshot Tests Updated - -The `target-python.test.js.snap` snapshot captures the full generated output -for all fixture packages. Snapshots were regenerated and show the expected -transformation: eager imports replaced by `_SUBMODULES` + `__getattr__` + -`__dir__` + `TYPE_CHECKING` block. - -### 4. Backwards Compatibility Preserved - -The following import patterns continue to work: - -| Pattern | Mechanism | -|---------|-----------| -| `import aws_cdk; aws_cdk.aws_s3` | `__getattr__` triggers lazy import | -| `from aws_cdk import aws_s3` | `__getattr__` triggers lazy import | -| `import aws_cdk.aws_s3` | Python's import system handles dotted imports directly | -| `from aws_cdk import *` | `__all__` includes submodule names; triggers lazy load | -| `dir(aws_cdk)` | `__dir__` returns all public names + submodules | - -### 5. Runtime Type Resolution Works - -When the jsii kernel returns a type from an unloaded submodule (e.g., during -a callback), the runtime: - -1. Detects the type is not registered -2. Derives the Python module path from the type's FQN -3. Imports the containing submodule (triggering type registration) -4. Retries the lookup — succeeds - -This was verified with the `jsii-calc` fixture which has nested submodules -(`cdk16625.donotimport`) specifically designed to test this scenario. - -## Profiling & Benchmarking - -### Step 1: Isolate import time (before — eager loading) - -Measure how long `import aws_cdk` takes with the current eager-loading code: - -```bash -# Using Python's built-in import profiler -python3 -X importtime -c "import aws_cdk" 2> eager_import_times.log - -# Human-readable summary (top-level time is the total) -python3 -c " -import time, sys -before = len(sys.modules) -t0 = time.perf_counter() -import aws_cdk -t1 = time.perf_counter() -after = len(sys.modules) -print(f'Import time: {(t1-t0)*1000:.0f} ms') -print(f'Modules loaded: {after - before}') -" -``` - -The `-X importtime` flag produces a tree showing every import with self and -cumulative time in microseconds.

But AWS wants customers to use CDK in Python, Java, C#, and Go too. Rather than maintaining 5 separate codebases, they built **jsii** — a system that: - -1. Takes the TypeScript CDK library -2. Generates wrapper libraries in each target language -3.

Specifically the import aws_cdk line. Familiarize yourself with virtual envs. - -**What this means:** - -The goal is to feel the problem firsthand. It's one thing to be told "imports are slow" — it's another to sit there watching your terminal hang for 6 seconds on a single `import` statement. - -**The commands (full sequence):** - -```bash -$ mkdir my-project -$ cd my-project -$ npx cdk@latest init app --language=python -$ source .venv/bin/activate -$ python -m pip install -r requirements.txt -$ time python -c "import aws_cdk" # ← feel the pain -``` - -Note: `npx cdk@latest init --language=python` and the official docs' `cdk init app --language python` do the same thing. `npx cdk@latest` runs the CDK CLI without installing it globally. `app` is the default template so omitting it is fine. - -**What `cdk init` creates:** - -``` -my-project/ -├── app.py ← entry point, has "import aws_cdk" -├── cdk.json ← CDK config -├── requirements.txt ← says "install aws-cdk-lib" -├── requirements-dev.txt -├── .venv/ ← Python virtual environment -├── .gitignore -├── README.md -├── source.bat -├── tests/ -│ └── unit/ -│ └── test_my_project_stack.py -└── my_project/ ← your app's Python package - ├── __init__.py - └── my_project_stack.py ← your stack definition -``` - -The subdirectory (`my_project/`) uses your project folder's name with hyphens converted to underscores (Python identifiers can't have hyphens). - -**What is a virtual environment?** - -A Python virtual environment (`.venv/`) is an isolated directory where pip installs packages. It keeps your project's dependencies separate from your system Python. You activate it with `source .venv/bin/activate`. After that, `pip install` puts packages into `.venv/lib/python3.x/site-packages/` instead of your global Python. - -**What you observed:** - -``` -$ time python -c "import aws_cdk" -python -c "import aws_cdk" 4.35s user 1.65s system 98% cpu 6.111 total -``` - -6.1 seconds for a single import. For comparison, `import json` takes ~0.02s and `import boto3` takes ~0.3s. CDK is 20x slower than boto3 and 300x slower than a standard library module. - -Every `cdk synth`, `cdk deploy`, `cdk diff` pays this tax before doing anything useful. - ---- - -### Phase 2: SEE THE BUILD POV - -**What your lead said:** -> Check out the CDK repository and build at least up to aws-cdk-lib: -> `$ yarn` -> `$ npx nx run aws-cdk-lib:build` -> Run pacmak to generate the Python code: -> `$ npx jsii-pacmak --targets python --code-only` -> Then have a look at what it generated in dist/python. - -**What this means:** - -You're looking at the **producer** side. The question is: where did that installed package come from?

Like `pip install` but for the whole project. - -2. **`npx nx run aws-cdk-lib:build`** — Compiles `aws-cdk-lib` from TypeScript. This produces: - - Compiled JavaScript (`.js` files) - - A **`.jsii` assembly file** — a massive JSON file (~50MB) describing every public type in the library - -3. **`npx jsii-pacmak --targets python --code-only`** — Reads the `.jsii` assembly and generates a complete Python package. `--targets python` means "only Python." `--code-only` means "just generate `.py` files, don't package into a wheel." - -**What it generates in `dist/python/`:** - -``` -dist/python/src/aws_cdk/ -├── __init__.py ← the root module (the slow one) -├── _jsii/ -│ └── __init__.py ← assembly loader -├── aws_s3/ -│ └── __init__.py ← S3 constructs -├── aws_lambda/ -│ └── __init__.py ← Lambda constructs -├── aws_ec2/ -│ └── __init__.py ← EC2 constructs -└── ...

The package published to PyPI is just this generated code, packaged up. - -**The key insight:** The Python code users install was NOT written by a human. It was generated by jsii-pacmak. To fix the slowness, you don't edit the Python files — you edit the TypeScript program that generates them. - -**Shortcut:** You can skip cloning the CDK repo for now. The generated output is already in your Phase 1 project at `.venv/lib/python3.x/site-packages/aws_cdk/`. It's the same code. - ---- - -### Phase 3: TRACE THIS BACK TO SOURCE - -**What your lead said:** -> Go and find the source for jsii-pacmak's Python generation and go peruse it. See how it maps to the code you saw in dist/python (and potentially in .venv/site-packages/python3.13/aws_cdk of your example project if you care to look) - -**What this means:** - -Connect the dots: which line of TypeScript code in jsii-pacmak produced which line of Python output? - -**The generator file:** - -``` -packages/jsii-pacmak/lib/targets/python.ts -``` - -This is ~3500 lines of TypeScript. The key class is `PythonModule`, which represents one Python module (one `__init__.py` file). - -**How the generator works:** - -It uses a `CodeMaker` object (called `code`) that's a string builder with indentation tracking: - -```typescript -code.line('import abc'); // writes: import abc -code.line('import builtins'); // writes: import builtins -code.openBlock('class Foo'); // writes: class Foo: (and increases indent) -code.line('pass'); // writes: pass -code.closeBlock(); // decreases indent -``` - -**The specific code that causes the problem (line ~1929 in python.ts):** - -```typescript -// Finally, we'll load all registered python modules -if (this.modules.length > 0) { - code.line( - '# Loading modules to ensure their types are registered with the jsii runtime library', - ); - for (const module of this.modules.sort((l, r) => - l.pythonName.localeCompare(r.pythonName), - )) { - const submodule = module.pythonName.substring( - this.pythonName.length + 1, - ); - code.line(`from . import ${submodule}`); - } -} -``` - -This loop iterates over every child module (~300 for aws-cdk-lib) and writes `from . import ` for each one. That's what produces the 300+ eager import lines at the bottom of `aws_cdk/__init__.py`. - -**The mapping:** - -| TypeScript generator code | Generated Python output | -|---|---| -| `code.line('import abc')` | `import abc` | -| `code.line('import jsii')` | `import jsii` | -| `code.line('publication.publish()')` | `publication.publish()` | -| `code.line(\`from . import ${submodule}\`)` in a loop | `from . import aws_s3`

... | - ---- - -## Part 6: The User's Flow (What Happens When They Run `cdk synth`) - -### The user has this file: - -```python -# app.py -from aws_cdk import App, Stack, aws_s3 - -class MyStack(Stack): - def __init__(self, scope, id): - super().__init__(scope, id) - aws_s3.Bucket(self, "MyBucket") - -app = App() -MyStack(app, "MyStack") -app.synth() -``` - -### They run: - -```bash -$ cdk synth -``` - -### Step 1: CDK CLI starts - -`cdk` is a Node.js program. It reads `cdk.json` which says: - -```json -{ "app": "python3 app.py" } -``` - -So the CDK CLI spawns a child process: `python3 app.py` - -### Step 2: Python starts executing `app.py` - -Python reads the first line: - -```python -from aws_cdk import App, Stack, aws_s3 -``` - -To execute this, Python needs to find and load the `aws_cdk` module. - -### Step 3: Python finds `aws_cdk` - -Python looks in `.venv/lib/python3.x/site-packages/` and finds the `aws_cdk/` directory. It opens `aws_cdk/__init__.py` and starts executing it **top to bottom**. - -### Step 4: Python executes `aws_cdk/__init__.py` - -This file is ~50,000 lines long. Here's what's in it (simplified): - -```python -# Line 1-10: standard imports -import abc -import builtins -import typing -import jsii -import publication - -# Line 11-45000: class definitions for root-level types -class App: - def __init__(self, ...): jsii.create(...) - -class Stack: - def __init__(self, ...): jsii.create(...) - -class CfnOutput: - ... - -# ... thousands more classes ... - -# Line 45001: export list -__all__ = ["App", "Stack", "CfnOutput", "aws_s3", "aws_lambda", ...] - -# Line 45002: hide non-public names -publication.publish() - -# Line 45003-45300: THE PROBLEM -from . import aws_accessanalyzer # ← Python goes and loads this entire module -from . import aws_acmpca # ← and this one -from . import aws_amplify # ← and this one -from . import aws_apigateway # ← and this one -# ... 300+ more lines like this -from . import aws_s3 # ← the user actually needs this one -# ... more ... -from . import aws_xray # ← and this one too -``` - -### Step 5: What happens at each `from . import` line - -When Python hits `from . import aws_s3`, it: - -1. Opens `aws_cdk/aws_s3/__init__.py` -2. Executes it top to bottom -3. That file defines ~200 classes (Bucket, BucketPolicy, CfnBucket, CfnBucketPolicy, etc.) -4. Each class definition triggers jsii registration (telling the jsii runtime "this Python class maps to this TypeScript type") -5. Returns back to `aws_cdk/__init__.py` and moves to the next line - -This happens **for every single `from . import` line**. 300+ times. Each submodule has dozens to hundreds of classes. Total: thousands of class definitions, thousands of jsii registrations. - -**The user only needed `App`, `Stack`, and `aws_s3`. But Python loaded all 300+ submodules because the `__init__.py` told it to.** - -### Step 6: Python finally finishes loading `aws_cdk` - -After 6 seconds, Python has executed all 300+ imports. Now it returns to `app.py` and resolves the names the user asked for: `App`, `Stack`, `aws_s3`. These are now available. - -### Step 7: User code runs - -```python -app = App() # sends "create App" to Node.js -MyStack(app, "MyStack") # sends "create Stack" to Node.js -aws_s3.Bucket(self, "MyBucket") # sends "create Bucket" to Node.js -app.synth() # tells Node.js to produce CloudFormation -``` - -Each of these calls goes through the jsii runtime to Node.js, which runs the real TypeScript code and produces a CloudFormation template. - -### Step 8: Output - -The CDK CLI receives the CloudFormation template from the Python process and prints it (or deploys it). - -### Where the 6 seconds went - -| Time | What's happening | -|---|---| -| 0.0s - 0.1s | Python starts, finds `aws_cdk` | -| 0.1s - 0.5s | Executes root-level class definitions (App, Stack, etc.) | -| 0.5s - 6.0s | **Loads 300+ submodules the user never asked for** | -| 6.0s - 6.1s | User code actually runs | - ---- - -## Part 7: The Build Pipeline (Producer Side) - -This is how the Python package gets created and published: - -``` -TypeScript source code (hand-written by CDK team) - │ - ▼ - tsc + jsii compiler - │ - ▼ - .jsii assembly (JSON manifest of the entire API — ~50MB) - │ - ▼ - jsii-pacmak (code generator — THIS IS WHAT YOU'RE MODIFYING) - │ - ▼ - Python source code (generated, not hand-written) - │ - ▼ - wheel/sdist (packaged for PyPI) - │ - ▼ - pip install (what users get) -``` - -### What the .jsii assembly contains - -A machine-readable catalog of every public type: - -```json -{ - "fqn": "aws-cdk-lib.aws_s3.Bucket", - "kind": "class", - "name": "Bucket", - "initializer": { - "parameters": [ - { "name": "scope", "type": { "fqn": "constructs.Construct" } }, - { "name": "id", "type": { "primitive": "string" } } - ] - }, - "properties": [ - { "name": "bucketArn", "type": { "primitive": "string" }, "immutable": true } - ] -} -``` - -### What pacmak generates from it - -```python -class Bucket(Resource): - def __init__(self, scope: Construct, id: str) -> None: - jsii.create(self.__class__, self, [scope, id]) - - @property - def bucket_arn(self) -> str: - return jsii.get(self, "bucketArn") -``` - -The generated Python class is a **puppet**. It doesn't contain business logic. When you call `Bucket(scope, id)`, the Python code sends a message to Node.js saying "create a Bucket with these args." Node.js runs the real TypeScript implementation and sends back a reference. - ---- - -## Part 8: What We're Changing - -We're modifying the TypeScript loop in `packages/jsii-pacmak/lib/targets/python.ts` so that instead of generating: - -```python -from . import aws_s3 -from . import aws_lambda -from . import aws_ec2 -# ... 300+ more -``` - -It generates: - -```python -import importlib as _importlib - -_SUBMODULES = {"aws_s3", "aws_lambda", "aws_ec2", ...} - -def __getattr__(name): - if name in _SUBMODULES: - mod = _importlib.import_module(f".{name}", __name__) - globals()[name] = mod - return mod - raise AttributeError(f"module {__name__!r} has no attribute {name!r}") - -def __dir__(): - return [*__all__, *_SUBMODULES] -``` - -### How this changes the user's experience - -With lazy loading, the user's `cdk synth` flow becomes: - -1. Python executes `from aws_cdk import App, Stack, aws_s3` -2. Python opens `aws_cdk/__init__.py` and starts executing it -3. It defines root-level classes (`App`, `Stack`, etc.) -4. It defines `_SUBMODULES = {"aws_s3", "aws_lambda", ...}` and `__getattr__` — **no actual imports happen** -5. Python sees the user wants `aws_s3` → calls `__getattr__("aws_s3")` → imports just that one module -6. Done. **~0.2 seconds instead of 6.** - -| Time | What's happening (after fix) | -|---|---| -| 0.0s - 0.1s | Python starts, finds `aws_cdk` | -| 0.1s - 0.2s | Executes root-level class definitions + defines `__getattr__` | -| 0.2s - 0.3s | Loads `aws_s3` only (because user asked for it) | -| 0.3s - 0.4s | User code runs | - -6 seconds → 0.4 seconds. The user's code doesn't change at all. - ---- - -## Part 9: Why the Eager Imports Existed in the First Place - -The comment in the generated code says: - -```python -# Loading modules to ensure their types are registered with the jsii runtime library -``` - -When the jsii runtime receives an object from Node.js (e.g., a method returns an `iam.Role`), it needs to know which Python class corresponds to `aws-cdk-lib.aws_iam.Role`. This mapping is built when each Python class is defined — the `@jsii.implements` decorator registers it. - -The original thinking was: "load everything upfront so the runtime always knows about every type." This is correct but wasteful. - -**Why lazy loading is safe:** By the time the jsii runtime needs to deserialize a type from `aws_s3`, the user must have already accessed `aws_s3` (otherwise how would they have gotten an `aws_s3.Bucket` in the first place?).

It lets you import modules using code (dynamically) rather than using the `import` statement. - -Source: [Python docs — importlib](https://docs.python.org/3/library/importlib.html) - -### Why `as _importlib` (the underscore prefix) - -The `as _importlib` renames it with an underscore prefix. In Python, underscore-prefixed names are a convention meaning "private / internal." The `publication.publish()` call later in the file hides all names NOT in `__all__` from `dir()` and tab-completion. Since `_importlib` starts with an underscore and isn't in `__all__`, it becomes invisible to users. - -Without the underscore, users doing `dir(aws_cdk)` would see `importlib` listed as if it were part of the CDK API. That would be confusing. - -### Why we need it at all - -We need `importlib.import_module()` to do the actual lazy import inside `__getattr__`. We can't use a regular `import` statement inside `__getattr__` because we need to do a **relative** import with a **dynamic** name (the name comes from the function parameter). The `import` statement requires the module name to be hardcoded at write time. - -### Comparison to the old approach - -In the old code, there was no `import importlib` because the imports were done with regular `from . import aws_s3` statements — no dynamic importing needed. - ---- - -## Lines 3-7: `_SUBMODULES = {"aws_s3", "aws_lambda", "aws_ec2"}` - -### What this is - -A Python **set literal** containing strings. A set is an unordered collection of unique items. Looking up whether something is in a set is O(1) — instant, regardless of how many items are in the set. - -### Why a set and not a list - -With 300+ submodule names, we need fast lookup. `if name in _SUBMODULES` is called every time someone accesses an attribute that doesn't exist yet. With a set, this check is instant. With a list, Python would scan through all 300 items one by one. - -### Why underscore prefix - -Same reason as `_importlib` — it's an internal implementation detail, not part of the public API. Hidden by `publication.publish()`. - -### What this replaces - -Previously, there was no `_SUBMODULES` set. The submodule names only existed as part of the `from . import aws_s3` statements. Those statements both declared the names AND loaded the modules. Now we separate the two concerns: `_SUBMODULES` declares the names, and `__getattr__` loads them on demand. - -### Why this is fast - -Creating a set of 300 strings takes microseconds. No files are opened, no modules are loaded, no classes are defined. It's just storing text in memory. - ---- - -## Line 9: `def __getattr__(name: str) -> object:` - -### What `__getattr__` is (on a class) - -You might know `__getattr__` from classes. On a class, it's a special method that Python calls when you access an attribute that doesn't exist: - -```python -class Foo: - def __getattr__(self, name): - return f"you asked for {name}" - -f = Foo() -print(f.xyz) # prints "you asked for xyz" -``` - -### What `__getattr__` is (on a module) — PEP 562 - -Since Python 3.7, you can define `__getattr__` at the **module level** (not inside a class). Python calls it when someone accesses an attribute on the module that doesn't exist in the module's namespace. - -Source: [PEP 562 – Module `__getattr__` and `__dir__`](https://www.python.org/dev/peps/pep-0562/) - -### When does Python call it? - -Python has a lookup order for module attributes: - -1. First, check the module's `__dict__` (its global namespace — all variables, functions, classes defined in the file) -2. If not found there, call `__getattr__(name)` if it exists -3. If `__getattr__` raises `AttributeError`, Python raises `AttributeError` to the caller - -### Why this is the key to lazy loading - -When the file first executes, `aws_s3` is NOT in the module's namespace (because we didn't import it). So when someone writes `aws_cdk.aws_s3`, Python doesn't find `aws_s3` in step 1, and calls `__getattr__("aws_s3")` in step 2. That's our hook to load it on demand. - -### Comparison to the old approach - -In the old code, there was no `__getattr__`. There didn't need to be — all submodules were already loaded into the namespace by the `from . import` statements. `aws_s3` was always found in step 1. - ---- - -## Line 10: `if name in _SUBMODULES:` - -### What this does - -Checks if the requested attribute name is one of our known submodules. This is a set membership test — O(1), instant. - -### Why we need this check - -`__getattr__` is called for ANY missing attribute, not just submodules. If someone writes `aws_cdk.nonexistent_thing`, we don't want to try importing it. We only want to lazily import names we know are valid submodules. - ---- - -## Line 11: `mod = _importlib.import_module(f".{name}", __name__)` - -### What `importlib.import_module` does - -It imports a module by name and returns the module object. It's the programmatic equivalent of the `import` statement. - -Source: [Python docs — importlib.import_module](https://docs.python.org/3/library/importlib.html#importlib.import_module) - -### What `f".{name}"` means - -This is an f-string (formatted string). If `name` is `"aws_s3"`, then `f".{name}"` becomes `".aws_s3"`. - -The leading dot (`.`) means "relative import" — import from the current package. This is equivalent to `from . import aws_s3`. - -### What `__name__` means - -`__name__` is a built-in variable that every Python module has. It contains the module's fully qualified name. For `aws_cdk/__init__.py`, `__name__` is `"aws_cdk"`. - -`importlib.import_module` needs this as the second argument to know what package the relative import is relative TO. It's saying: "import `.aws_s3` relative to the `aws_cdk` package." - -### What this is equivalent to - -```python -mod = _importlib.import_module(".aws_s3", "aws_cdk") -``` - -Which is equivalent to: - -```python -from . import aws_s3 -mod = aws_s3 -``` - -### How Python caches imports (sys.modules) - -When Python imports a module, it stores it in `sys.modules` (a global dictionary). If you import the same module again, Python returns the cached version from `sys.modules` without re-executing the file. This is Python's built-in import caching. - -Source: [Python docs — The import system](https://docs.python.org/3/reference/import.html) - -So `importlib.import_module` is safe to call multiple times — the second call just returns the cached module. But we add our own caching too (next line) to avoid even calling `__getattr__` a second time. - ---- - -## Line 12: `globals()[name] = mod` - -### What `globals()` is - -`globals()` returns a dictionary representing the current module's global namespace. It's a live reference — modifying it actually modifies the module's namespace. - -Source: [Python docs — globals()](https://docs.python.org/3/library/functions.html#globals) - -For a module, `globals()` is the same as the module's `__dict__`. It contains every variable, function, and class defined at the module level. - -### What this line does - -It adds the imported module to the module's namespace. After `globals()["aws_s3"] = mod`, the module now has `aws_s3` as a regular attribute. - -### Why this is "caching" - -Remember Python's lookup order: -1. Check `__dict__` (globals) -2. If not found, call `__getattr__` - -After we do `globals()[name] = mod`, the next time someone accesses `aws_cdk.aws_s3`, Python finds it in step 1 and **never calls `__getattr__` again** for that name. The lazy loading only happens once per submodule. - -### How caching worked before (in the old approach) - -In the old code with `from . import aws_s3`, Python automatically put `aws_s3` into the module's globals when the import statement executed. So it was "cached" from the start — but at the cost of loading everything upfront. - -Our approach achieves the same end state (module in globals), but defers it until first access. - -### Why not just rely on `sys.modules` caching? - -`sys.modules` caching means `importlib.import_module` won't re-execute the file. But without `globals()[name] = mod`, Python would still call `__getattr__` every single time someone accesses `aws_cdk.aws_s3` (because it's not in the module's `__dict__`). That would add overhead on every access. By putting it in globals, we make subsequent accesses as fast as if we'd done the eager import. - ---- - -## Line 13: `return mod` - -### What this does - -Returns the imported module to whoever asked for it. If the user wrote `aws_cdk.aws_s3.Bucket(...)`, Python called `__getattr__("aws_s3")`, we imported the module, cached it, and now return it. Python then continues with `.Bucket(...)` on the returned module. - ---- - -## Line 14: `raise AttributeError(f"module {__name__!r} has no attribute {name!r}")` - -### Why we raise an error - -If someone accesses `aws_cdk.totally_fake_thing`, the name won't be in `_SUBMODULES`. We need to tell Python "this attribute doesn't exist." The way to do that is by raising `AttributeError`. - -### Why specifically `AttributeError` - -This is a Python protocol requirement. `__getattr__` MUST raise `AttributeError` for names it can't handle. Python relies on this: - -- `hasattr(aws_cdk, "fake")` works by calling `__getattr__("fake")` and checking if it raises `AttributeError`. If it does, `hasattr` returns `False`. If we raised a different exception (like `ValueError`), `hasattr` would crash instead of returning `False`. -- `getattr(aws_cdk, "fake", default_value)` works the same way — it catches `AttributeError` and returns the default. - -### Did the old code raise this error? - -Not explicitly — but the behavior was the same. In the old code, if you accessed `aws_cdk.totally_fake_thing`, Python would look in the module's `__dict__`, not find it, and raise `AttributeError` automatically (since there was no `__getattr__` to call). Now we have `__getattr__`, so we need to raise the error ourselves for unknown names. - -### What `{__name__!r}` means - -The `!r` is a format specifier that adds quotes around the value. `__name__` is `"aws_cdk"`, so `{__name__!r}` produces `'aws_cdk'` (with quotes). The error message looks like: - -``` -AttributeError: module 'aws_cdk' has no attribute 'totally_fake_thing' -``` - -This matches Python's standard error message format for missing module attributes. - ---- - -## Lines 16-17: `def __dir__() -> list[str]: return [*__all__, *_SUBMODULES]` - -### What `__dir__` does on a module - -When someone calls `dir(aws_cdk)`, Python calls the module's `__dir__()` function (if defined) to get the list of names to display. - -Source: [PEP 562 – Module `__getattr__` and `__dir__`](https://www.python.org/dev/peps/pep-0562/) - -### Why we need it - -Without `__dir__`, `dir(aws_cdk)` would only show names that are currently in the module's `__dict__`. Since submodules aren't loaded yet, they wouldn't appear. Tab-completion in IPython/Jupyter and IDE autocomplete rely on `dir()`, so submodules would be invisible to developers exploring the API. - -### What `[*__all__, *_SUBMODULES]` means - -The `*` operator unpacks a collection into a list. This creates a new list containing all items from `__all__` plus all items from `_SUBMODULES`. - -- `__all__` contains the public names (classes like `App`, `Stack`, plus submodule names) -- `_SUBMODULES` contains the submodule names - -There's overlap (submodule names are in both), but that's fine — it's just a display list. - -### Did the old code have `__dir__`? - -No. It didn't need one because all submodules were already loaded into globals, so `dir()` naturally included them. - ---- - -## Summary: Old vs New - -| Aspect | Old (eager) | New (lazy) | -|---|---|---| -| How submodules are declared | `from . import aws_s3` (loads immediately) | `_SUBMODULES = {"aws_s3"}` (just a string) | -| When submodules are loaded | All at once, during `import aws_cdk` | One at a time, when first accessed | -| How loading is triggered | Python's `import` statement | `__getattr__` + `importlib.import_module` | -| How results are cached | Automatically in globals by `import` | Manually via `globals()[name] = mod` | -| How missing attrs are handled | Python raises `AttributeError` automatically | We raise `AttributeError` in `__getattr__` | -| How `dir()` works | Shows all names (already in globals) | Custom `__dir__` returns `__all__` + `_SUBMODULES` | -| Import time for `aws_cdk` | ~6 seconds (loads 300 modules) | ~0.2 seconds (loads nothing) | - ---- - -## Sources -
