# Architectural Review: Error Handling in Web Routes
|
||||
|
||||
**Review Date**: 2025-11-18
|
||||
**Reviewer**: Architect Agent
|
||||
**Status**: Analysis Complete - Recommendation Provided
|
||||
**Related Test Failure**: `test_update_nonexistent_note_404` in `tests/test_routes_admin.py:386`
|
||||
|
||||
## Executive Summary
|
||||
|
||||
A test expects `POST /admin/edit/99999` (updating a nonexistent note) to return HTTP 404, but the current implementation returns HTTP 302 (redirect). This mismatch reveals an inconsistency in error handling patterns between GET and POST routes.
|
||||
|
||||
**Recommendation**: Fix the implementation to match the test expectation. The POST route should return 404 when the resource doesn't exist, consistent with the GET route behavior.
|
||||
|
||||
## Problem Statement
|
||||
|
||||
### The Test Failure
|
||||
|
||||
```python
|
||||
def test_update_nonexistent_note_404(self, authenticated_client):
|
||||
"""Test that updating a nonexistent note returns 404"""
|
||||
response = authenticated_client.post(
|
||||
"/admin/edit/99999",
|
||||
data={"content": "Updated content", "published": "on"},
|
||||
follow_redirects=False,
|
||||
)
|
||||
assert response.status_code == 404 # EXPECTED: 404
|
||||
# ACTUAL: 302
|
||||
```
|
||||
|
||||
### Current Implementation Behavior
|
||||
|
||||
The `update_note_submit()` function in `/home/phil/Projects/starpunk/starpunk/routes/admin.py` (lines 127-164) does not check if the note exists before attempting to update it. When `update_note()` raises `NoteNotFoundError`, the exception is caught by the generic `Exception` handler, which:
|
||||
|
||||
1. Flashes an error message
|
||||
2. Redirects to the edit form: `redirect(url_for("admin.edit_note_form", note_id=note_id))`
|
||||
3. Returns HTTP 302
|
||||
|
||||
This redirect then fails (since the note doesn't exist), but the initial response is still 302, not 404.
|
||||
|
||||
## Root Cause Analysis
|
||||
|
||||
### Pattern Inconsistency
|
||||
|
||||
The codebase has **inconsistent error handling** between GET and POST routes:
|
||||
|
||||
1. **GET `/admin/edit/<note_id>` (lines 100-124)**: Explicitly checks for note existence
|
||||
```python
|
||||
note = get_note(id=note_id)
|
||||
if not note:
|
||||
flash("Note not found", "error")
|
||||
return redirect(url_for("admin.dashboard")), 404 # ✓ Returns 404
|
||||
```
|
||||
|
||||
2. **POST `/admin/edit/<note_id>` (lines 127-164)**: Does NOT check for note existence
|
||||
```python
|
||||
try:
|
||||
note = update_note(id=note_id, content=content, published=published)
|
||||
# ... success handling
|
||||
except ValueError as e: # ← Catches InvalidNoteDataError
|
||||
flash(f"Error updating note: {e}", "error")
|
||||
return redirect(url_for("admin.edit_note_form", note_id=note_id)) # ✗ Returns 302
|
||||
except Exception as e: # ← Would catch NoteNotFoundError
|
||||
flash(f"Unexpected error updating note: {e}", "error")
|
||||
return redirect(url_for("admin.edit_note_form", note_id=note_id)) # ✗ Returns 302
|
||||
```
|
||||
|
||||
### Why This Matters
|
||||
|
||||
The `update_note()` function in `starpunk/notes.py` raises `NoteNotFoundError` (lines 605-607) when the note doesn't exist:
|
||||
|
||||
```python
|
||||
existing_note = get_note(slug=slug, id=id, load_content=False)
|
||||
if existing_note is None:
|
||||
identifier = slug if slug is not None else id
|
||||
raise NoteNotFoundError(identifier) # ← This exception is raised
|
||||
```
|
||||
|
||||
Since `NoteNotFoundError` is a subclass of `NoteError` (which extends `Exception`), it gets caught by the generic `except Exception` handler in the route, resulting in a redirect instead of a 404.
|
||||
|
||||
## Existing Pattern Analysis
|
||||
|
||||
### Pattern 1: GET Route for Edit Form (CORRECT)
|
||||
|
||||
**File**: `starpunk/routes/admin.py` lines 100-124
|
||||
|
||||
```python
|
||||
@bp.route("/edit/<int:note_id>", methods=["GET"])
|
||||
@require_auth
|
||||
def edit_note_form(note_id: int):
|
||||
note = get_note(id=note_id)
|
||||
|
||||
if not note:
|
||||
flash("Note not found", "error")
|
||||
return redirect(url_for("admin.dashboard")), 404 # ✓ CORRECT
|
||||
|
||||
return render_template("admin/edit.html", note=note)
|
||||
```
|
||||
|
||||
**Status Code**: 404
|
||||
**User Experience**: Redirects to dashboard with flash message
|
||||
**Test**: `test_edit_nonexistent_note_404` (line 376) - PASSES
|
||||
|
||||
### Pattern 2: DELETE Route (INCONSISTENT)
|
||||
|
||||
**File**: `starpunk/routes/admin.py` lines 167-200
|
||||
|
||||
The delete route does NOT explicitly check if the note exists. It relies on `delete_note()` which is idempotent and returns successfully even if the note doesn't exist (see `starpunk/notes.py` lines 774-778).
|
||||
|
||||
**Test**: `test_delete_nonexistent_note_shows_error` (line 443)
|
||||
```python
|
||||
response = authenticated_client.post(
|
||||
"/admin/delete/99999",
|
||||
data={"confirm": "yes"},
|
||||
follow_redirects=True
|
||||
)
|
||||
assert response.status_code == 200 # ← Expects redirect + success (200 after following redirect)
|
||||
assert b"error" in response.data.lower() or b"not found" in response.data.lower()
|
||||
```
|
||||
|
||||
This test shows a **different expectation**: it expects a redirect (200 after following) with an error message, NOT a 404.
|
||||
|
||||
However, looking at the `delete_note()` implementation, it's **idempotent** - it returns successfully even if the note doesn't exist. This means the delete route won't flash an error for nonexistent notes unless we add explicit checking.
|
||||
|
||||
## REST vs Web Form Patterns
|
||||
|
||||
### Two Valid Approaches
|
||||
|
||||
#### Approach A: REST-Style (Strict HTTP Semantics)
|
||||
- **404 for all operations** on nonexistent resources
|
||||
- Applies to both GET and POST
|
||||
- More "API-like" behavior
|
||||
- Better for programmatic clients
|
||||
|
||||
#### Approach B: Web-Form-Friendly (User Experience First)
|
||||
- **404 for GET** (can't show the form)
|
||||
- **302 redirect for POST** (show error message to user)
|
||||
- More common in traditional web applications
|
||||
- Better user experience (shows error in context)
|
||||
|
||||
### Which Approach for StarPunk?
|
||||
|
||||
Looking at the test suite:
|
||||
|
||||
1. **GET route test** (line 376): Expects 404 ✓
|
||||
2. **POST route test** (line 381): Expects 404 ✓
|
||||
3. **DELETE route test** (line 443): Expects 200 (redirect + error message) ✗
|
||||
|
||||
The test suite is **inconsistent**. However, the edit tests (`test_edit_nonexistent_note_404` and `test_update_nonexistent_note_404`) both expect 404, suggesting the intent is **Approach A: REST-Style**.
|
||||
|
||||
## Architectural Decision
|
||||
|
||||
### Recommendation: Approach A (REST-Style)
|
||||
|
||||
**All operations on nonexistent resources should return 404**, regardless of HTTP method.
|
||||
|
||||
### Rationale
|
||||
|
||||
1. **Consistency**: GET already returns 404, POST should match
|
||||
2. **Test Intent**: Both tests expect 404
|
||||
3. **API Future**: StarPunk will eventually have Micropub API - REST patterns will be needed
|
||||
4. **Correctness**: HTTP 404 is the semantically correct response for "resource not found"
|
||||
5. **Debugging**: Clearer error signaling for developers and future API consumers
|
||||
|
||||
### Trade-offs
|
||||
|
||||
**Pros**:
|
||||
- Consistent HTTP semantics
|
||||
- Easier to reason about
|
||||
- Better for future API development
|
||||
- Test suite alignment
|
||||
|
||||
**Cons**:
|
||||
- Slightly worse UX (user sees error page instead of flash message)
|
||||
- Requires custom 404 error handler for good UX
|
||||
- More routes need explicit existence checks
|
||||
|
||||
**Mitigation**: Implement custom 404 error handler that shows user-friendly message with navigation back to dashboard.
|
||||
|
||||
## Implementation Plan
|
||||
|
||||
### Changes Required
|
||||
|
||||
#### 1. Fix `update_note_submit()` in `starpunk/routes/admin.py`
|
||||
|
||||
**Current** (lines 127-164):
|
||||
```python
|
||||
@bp.route("/edit/<int:note_id>", methods=["POST"])
|
||||
@require_auth
|
||||
def update_note_submit(note_id: int):
|
||||
content = request.form.get("content", "").strip()
|
||||
published = "published" in request.form
|
||||
|
||||
if not content:
|
||||
flash("Content cannot be empty", "error")
|
||||
return redirect(url_for("admin.edit_note_form", note_id=note_id))
|
||||
|
||||
try:
|
||||
note = update_note(id=note_id, content=content, published=published)
|
||||
flash(f"Note updated: {note.slug}", "success")
|
||||
return redirect(url_for("admin.dashboard"))
|
||||
except ValueError as e:
|
||||
flash(f"Error updating note: {e}", "error")
|
||||
return redirect(url_for("admin.edit_note_form", note_id=note_id))
|
||||
except Exception as e:
|
||||
flash(f"Unexpected error updating note: {e}", "error")
|
||||
return redirect(url_for("admin.edit_note_form", note_id=note_id))
|
||||
```
|
||||
|
||||
**Proposed**:
|
||||
```python
|
||||
@bp.route("/edit/<int:note_id>", methods=["POST"])
|
||||
@require_auth
|
||||
def update_note_submit(note_id: int):
|
||||
# CHECK IF NOTE EXISTS FIRST
|
||||
from starpunk.notes import NoteNotFoundError
|
||||
|
||||
existing_note = get_note(id=note_id, load_content=False)
|
||||
if not existing_note:
|
||||
flash("Note not found", "error")
|
||||
return redirect(url_for("admin.dashboard")), 404
|
||||
|
||||
content = request.form.get("content", "").strip()
|
||||
published = "published" in request.form
|
||||
|
||||
if not content:
|
||||
flash("Content cannot be empty", "error")
|
||||
return redirect(url_for("admin.edit_note_form", note_id=note_id))
|
||||
|
||||
try:
|
||||
note = update_note(id=note_id, content=content, published=published)
|
||||
flash(f"Note updated: {note.slug}", "success")
|
||||
return redirect(url_for("admin.dashboard"))
|
||||
except ValueError as e:
|
||||
flash(f"Error updating note: {e}", "error")
|
||||
return redirect(url_for("admin.edit_note_form", note_id=note_id))
|
||||
except Exception as e:
|
||||
flash(f"Unexpected error updating note: {e}", "error")
|
||||
return redirect(url_for("admin.edit_note_form", note_id=note_id))
|
||||
```
|
||||
|
||||
#### 2. Fix DELETE route consistency (OPTIONAL)
|
||||
|
||||
The delete route should also check for existence:
|
||||
|
||||
**Add to `delete_note_submit()` before deletion**:
|
||||
```python
|
||||
@bp.route("/delete/<int:note_id>", methods=["POST"])
|
||||
@require_auth
|
||||
def delete_note_submit(note_id: int):
|
||||
# Check for confirmation
|
||||
if request.form.get("confirm") != "yes":
|
||||
flash("Deletion cancelled", "info")
|
||||
return redirect(url_for("admin.dashboard"))
|
||||
|
||||
# CHECK IF NOTE EXISTS
|
||||
existing_note = get_note(id=note_id, load_content=False)
|
||||
if not existing_note:
|
||||
flash("Note not found", "error")
|
||||
return redirect(url_for("admin.dashboard")), 404
|
||||
|
||||
try:
|
||||
delete_note(id=note_id, soft=False)
|
||||
flash("Note deleted successfully", "success")
|
||||
except ValueError as e:
|
||||
flash(f"Error deleting note: {e}", "error")
|
||||
except Exception as e:
|
||||
flash(f"Unexpected error deleting note: {e}", "error")
|
||||
|
||||
return redirect(url_for("admin.dashboard"))
|
||||
```
|
||||
|
||||
**However**: The test `test_delete_nonexistent_note_shows_error` expects 200 (redirect), not 404. This test may need updating, or we accept the inconsistency for delete operations (which are idempotent).
|
||||
|
||||
**Recommendation**: Update the delete test to expect 404 for consistency.
|
||||
|
||||
### Testing Strategy
|
||||
|
||||
After implementing the fix:
|
||||
|
||||
1. Run `test_update_nonexistent_note_404` - should PASS
|
||||
2. Run `test_edit_nonexistent_note_404` - should still PASS
|
||||
3. Run full test suite to check for regressions
|
||||
4. Consider updating `test_delete_nonexistent_note_shows_error` to expect 404
|
||||
|
||||
## Consistency Matrix
|
||||
|
||||
| Route | Method | Resource Missing | Current Behavior | Expected Behavior | Status |
|
||||
|-------|--------|------------------|------------------|-------------------|--------|
|
||||
| `/admin/edit/<id>` | GET | Returns 404 | 404 | 404 | ✓ CORRECT |
|
||||
| `/admin/edit/<id>` | POST | Returns 302 | 302 | 404 | ✗ FIX NEEDED |
|
||||
| `/admin/delete/<id>` | POST | Returns 302 | 302 | 404? | ⚠ INCONSISTENT TEST |
|
||||
|
||||
## Additional Recommendations
|
||||
|
||||
### 1. Create Architecture Decision Record
|
||||
|
||||
Document this decision in `/home/phil/Projects/starpunk/docs/decisions/ADR-012-error-handling-http-status-codes.md`
|
||||
|
||||
### 2. Create Error Handling Standard
|
||||
|
||||
Document error handling patterns in `/home/phil/Projects/starpunk/docs/standards/http-error-handling.md`:
|
||||
|
||||
- When to return 404 vs redirect
|
||||
- How to handle validation errors
|
||||
- Flash message patterns
|
||||
- Custom error pages
|
||||
|
||||
### 3. Exception Hierarchy Review
|
||||
|
||||
The exception handling in routes could be more specific:
|
||||
|
||||
```python
|
||||
except NoteNotFoundError as e: # ← Should have been caught earlier
|
||||
# This shouldn't happen now that we check first
|
||||
flash("Note not found", "error")
|
||||
return redirect(url_for("admin.dashboard")), 404
|
||||
except InvalidNoteDataError as e: # ← More specific than ValueError
|
||||
flash(f"Invalid data: {e}", "error")
|
||||
return redirect(url_for("admin.edit_note_form", note_id=note_id))
|
||||
except NoteSyncError as e: # ← File/DB sync issues
|
||||
flash(f"System error: {e}", "error")
|
||||
return redirect(url_for("admin.dashboard")), 500
|
||||
except Exception as e: # ← Truly unexpected
|
||||
current_app.logger.error(f"Unexpected error in update_note_submit: {e}")
|
||||
flash("An unexpected error occurred", "error")
|
||||
return redirect(url_for("admin.dashboard")), 500
|
||||
```
|
||||
|
||||
However, with the existence check at the start, `NoteNotFoundError` should never be raised from `update_note()`.
|
||||
|
||||
## Decision Summary
|
||||
|
||||
### The Fix
|
||||
|
||||
**Change `/home/phil/Projects/starpunk/starpunk/routes/admin.py` line 129-154**:
|
||||
|
||||
Add existence check before processing form data:
|
||||
|
||||
```python
|
||||
# Add after function definition, before form processing
|
||||
existing_note = get_note(id=note_id, load_content=False)
|
||||
if not existing_note:
|
||||
flash("Note not found", "error")
|
||||
return redirect(url_for("admin.dashboard")), 404
|
||||
```
|
||||
|
||||
### Why This is the Right Approach
|
||||
|
||||
1. **Matches existing pattern**: GET route already does this (line 118-122)
|
||||
2. **Matches test expectations**: Both edit tests expect 404
|
||||
3. **HTTP correctness**: 404 is the right status for missing resources
|
||||
4. **Future-proof**: Will work correctly when Micropub API is added
|
||||
5. **Simple fix**: Minimal code change, high consistency gain
|
||||
|
||||
### What NOT to Do
|
||||
|
||||
**Do NOT** change the test to expect 302. The test is correct; the implementation is wrong.
|
||||
|
||||
**Reason**:
|
||||
- Redirecting on POST to a nonexistent resource is semantically incorrect
|
||||
- Makes debugging harder (did the update fail, or does the resource not exist?)
|
||||
- Inconsistent with GET behavior
|
||||
- Bad pattern for future API development
|
||||
|
||||
## Conclusion
|
||||
|
||||
This is a bug in the implementation, not the test. The fix is straightforward: add an existence check at the start of `update_note_submit()`, matching the pattern used in `edit_note_form()`.
|
||||
|
||||
This architectural pattern should be applied consistently across all routes:
|
||||
1. Check resource existence first
|
||||
2. Return 404 if not found (with user-friendly flash message)
|
||||
3. Validate input
|
||||
4. Perform operation
|
||||
5. Handle expected exceptions
|
||||
6. Return appropriate status codes
|
||||
|
||||
**Next Steps**:
|
||||
1. Implement the fix in `update_note_submit()`
|
||||
2. Run tests to verify fix
|
||||
3. Consider fixing delete route for consistency
|
||||
4. Document pattern in standards
|
||||
5. Create ADR for HTTP error handling policy

||||
|
||||
**Performance Issues**: NONE
|
||||
|
||||
---
|
||||
|
||||
## Issues Found
|
||||
|
||||
### Critical Issues: NONE
|
||||
|
||||
No critical issues found. Implementation is production-ready.
|
||||
|
||||
---
|
||||
|
||||

|
||||
|
||||
---
|
||||
|
||||
### Minor Issues: 1
|
||||
|
||||
**MINOR-1: Flake8 Configuration Mismatch**
|
||||
|
||||
**Severity**: Minor (cosmetic/tooling)
|
||||
|
||||
**Description**:
|
||||
The codebase uses Black (88 character line length) but flake8 is configured for 79 characters, causing false positive E501 warnings on 12 lines.
|
||||
|
||||
**Impact**:
|
||||
Cosmetic only. Does not affect code quality, security, or functionality. Causes CI/pre-commit noise.
|
||||
|
||||
**Recommendation**:
|
||||
Create `setup.cfg` or `.flake8` configuration file:
|
||||
|
||||
```ini
|
||||
[flake8]
|
||||
max-line-length = 88
|
||||
extend-ignore = E203, W503
|
||||
exclude =
|
||||
.venv,
|
||||
__pycache__,
|
||||
data,
|
||||
.git
|
||||
```
|
||||
|
||||
**Priority**: Low (tooling configuration)
|
||||
**Assigned to**: Developer (can be fixed in separate commit)
|
||||
|
||||
---
|
||||
|
||||
## Recommendations
|
||||
|
||||
### Immediate Actions (Before Merge)
|
||||
|
||||
1. **OPTIONAL**: Add flake8 configuration file to resolve E501 warnings
|
||||
- This is a project-wide tooling issue, not specific to this implementation
|
||||
- Can be addressed in a separate tooling/configuration commit
|
||||
- Does not block merge
|
||||
|
||||
### Post-Merge Improvements (V2 or Later)
|
||||
|
||||
1. **Rate Limiting**: Consider adding rate limiting middleware
|
||||
- Current design delegates to reverse proxy (acceptable for V1)
|
||||
- Could add application-level limiting in V2
|
||||
|
||||
2. **Automatic Session Cleanup**: Add scheduled cleanup job
|
||||
- Current lazy cleanup is acceptable for V1
|
||||
- Consider cron job or background task for V2
|
||||
|
||||
3. **2FA Support**: Potential future enhancement
|
||||
- Not required for V1 (relies on IndieLogin's security)
|
||||
- Could add as optional V2 feature
|
||||
|
||||
4. **Multi-User Support**: Plan for future expansion
|
||||
- V1 intentionally single-user
|
||||
- Database schema supports expansion (me field is generic)
|
||||
|
||||
5. **Session Management UI**: Admin panel for sessions
|
||||
- Show active sessions
|
||||
- Revoke individual sessions
|
||||
- View audit trail
