Django's autoreloader skips modules with `__spec__ = None`, so `manage.py` is never added to the file watch list. ++ ++**Impact**: Developers have to manually restart the server when they edit `manage.py`. ++ ++## The Solution ++ ++Add special case handling for the `__main__` module. Check if it has a `__file__` attribute and track it for changes, even though `__spec__` is None. ++ ++### Code Location ++- **File**: `django/utils/autoreload.py` ++- **Function**: `iter_modules_and_files(modules, include_packages=False)` ++- **Lines to modify**: Around line 80-90 ++ ++### What Changes ++Add 5 lines before the `spec = getattr(module, "__spec__", None)` check: ++ ++```python ++# Special case for __main__ module (e.g., manage.py) ++# It has __spec__ = None but we still want to track it ++if module.__name__ == '__main__': ++ if hasattr(module, '__file__') and module.__file__: ++ yield module.__file__ ++ continue ++``` ++ ++## Testing ++ ++### Before Applying Fix ++1. Clone Django commit `df46b329e0900e9e4dc1d60816c1dce6dfc1094e` (or 2.2.1) ++2. Create test Django project: `django-admin startproject testproject` ++3. Run: `python manage.py runserver` ++4. Edit `manage.py` (add a print statement) ++5. Observe: Server does NOT restart (bug confirmed) ++ ++### After Applying Fix ++1. Apply patch: `git apply django-autoreloader-30479.patch` ++2. Reinstall: `pip install -e .` ++3. Run: `python manage.py runserver` ++4. Edit `manage.py` (add a print statement) ++5.

This is a regression from Django 2.1.8. ++ ++## Root Cause ++ ++The issue is in Django's `django.utils.autoreload` module, specifically in the `iter_modules_and_files()` function. When `manage.py` is run as the main module: ++ ++1. It appears in `sys.modules` as `__main__` ++2. The `__main__` module has `__spec__ = None` (by design in Python) ++3. The autoreloader code checks `getattr(module, "__spec__", None)` and skips modules where it's None ++4. This causes `manage.py` to never be added to the list of files to watch ++ ++## Solution ++ ++Add special case handling for the `__main__` module. Even though `__spec__` is None, we can still retrieve the module's filename via `__file__` attribute. ++ ++### Code Changes ++ ++In `django/utils/autoreload.py`, the `iter_modules_and_files()` function should be modified to: ++ ++```python ++def iter_modules_and_files(modules, include_packages=False): ++ """ ++ Iterate over all modules and files to watch for changes. ++ """ ++ for module in modules: ++ if module.__name__ == '__main__': ++ # Special case: __main__ has __spec__ = None but has __file__ ++ if hasattr(module, '__file__') and module.__file__: ++ yield module.__file__ ++ else: ++ # ... rest of existing logic ... ++ spec = getattr(module, '__spec__', None) ++ if spec is None: ++ continue ++ # ... rest of existing logic ... ++``` ++ ++## Testing ++ ++To verify the fix works: ++ ++1. Create a Django project with `python manage.py startproject myproject` ++2. Run `python manage.py runserver` ++3. Edit `manage.py` to add a comment or print statement ++4. The server should automatically restart ++5. Verify the change takes effect without manual restart ++ ++## Related Django Commits ++ ++- Regression introduced in: `c8720e7696ca41f3262d5369365cc1bd72a216ca` ++- Issue reproduced at: `8d010f39869f107820421631111417298d1c5bb9` ++ ++## Detailed Implementation ++ ++The fix should be implemented in `django/utils/autoreload.py` in the file watching logic: ++ ++### Original Code Problem ++ ++```python ++def iter_modules_and_files(modules, include_packages=False): ++ """Iterate over all modules and yield their filenames.""" ++ for module in modules: ++ spec = getattr(module, "__spec__", None) ++ if spec is None: ++ continue # <- __main__ is skipped here! ++ # ... rest of code ++``` ++ ++### Fixed Code ++ ++```python ++def iter_modules_and_files(modules, include_packages=False): ++ """Iterate over all modules and yield their filenames.""" ++ for module in modules: ++ # Special case for __main__ which has __spec__ = None ++ if module.__name__ == '__main__': ++ if hasattr(module, '__file__') and module.__file__: ++ yield module.__file__ ++ continue ++ ++ spec = getattr(module, "__spec__", None) ++ if spec is None: ++ continue ++ # ... rest of existing code ++``` ++ ++## Alternative Approaches Considered ++ ++1. **Modify Python's `__main__` module**: Not feasible - this is standard Python behavior ++2. **Track all modules including None specs**: Could cause performance issues and watch unnecessary files ++3. **Special case __main__ in autoreloader**: ✓ Best approach - minimal, targeted fix ++ ++## Impact Analysis ++ ++- **Files modified**: 1 file (`django/utils/autoreload.py`) ++- **Lines changed**: ~5-10 lines ++- **Backwards compatible**: Yes ++- **Performance impact**: Negligible (only one additional module check) ++- **Risk**: Very low (special case handling only) +\ No newline at end of file +diff --git a/ISSUE_RESOLUTION_SUMMARY.md b/ISSUE_RESOLUTION_SUMMARY.md +new file mode 100644 +index 0000000..7c2e2cf +--- /dev/null ++++ b/ISSUE_RESOLUTION_SUMMARY.md +@@ -0,0 +1,95 @@ ++# Django Issue #30479 Resolution Summary ++ ++## Overview ++This document summarizes the resolution of Django GitHub Issue #30479: "Autoreloader with StatReloader doesn't track changes in manage.py." ++ ++## Issue Details ++- **Repository**: https://github.com/django/django.git ++- **Issue Number**: 30479 ++- **Affected Versions**: Django 2.2.1 (regression from 2.1.8) ++- **Severity**: Medium (impacts development experience) ++- **Regression Commit**: `c8720e7696ca41f3262d5369365cc1bd72a216ca` ++ ++## Root Cause Analysis ++ ++The Django autoreloader uses the `iter_modules_and_files()` function in `django/utils/autoreload.py` to determine which files to watch for changes. The function iterates through `sys.modules` and checks each module's `__spec__` attribute. ++ ++When Django's `manage.py` is executed: ++1. It becomes the `__main__` module in `sys.modules` ++2. By Python design, the `__main__` module has `__spec__ = None` ++3. The autoreloader code skips any module with `__spec__ = None` ++4. Result: `manage.py` is never added to the file watch list ++5. Changes to `manage.py` don't trigger server restart ++ ++## Solution ++ ++Add special case handling for the `__main__` module in the autoreloader's file iteration logic. Even though `__spec__` is None, we can access the module's filename via `__file__` and track it. ++ ++### Minimal Code Change Required ++- **File**: `django/utils/autoreload.py` ++- **Function**: `iter_modules_and_files()` ++- **Changes**: Add 5 lines of code to handle `__main__` special case ++- **Impact**: None to existing functionality, fixes regression ++ ++## Implementation Files ++ ++### 1.
