||||
2. User verifies DNS verification works
|
||||
3. User tests with 2+ IndieAuth clients
|
||||
4. Architect reviews results
|
||||
5. Decision: Release v1.0.0 or create rc.9
|
||||
|
||||
### Success Criteria for v1.0.0 Release
|
||||
|
||||
The following must be confirmed:
|
||||
1. DNS verification works with real DNS records ✅
|
||||
2. At least 2 different IndieAuth clients authenticate successfully
|
||||
3. No critical bugs found during client testing
|
||||
4. All security tests continue to pass
|
||||
5. Production server stable for 24+ hours
|
||||
|
||||
Once these criteria are met, we can confidently release v1.0.0.
|
||||
|

# ADR-011. DNS TXT Record Subdomain Prefix
|
||||
|
||||
Date: 2024-11-22
|
||||
|
||||
## Status
|
||||
Accepted
|
||||
|
||||
## Context
|
||||
|
||||
For DNS-based domain verification, we need users to prove they control a domain by setting a TXT record. There are two common approaches:
|
||||
|
||||
1. **Direct domain TXT record**: Place the verification value directly on the domain (e.g., TXT record on `example.com`)
|
||||
2. **Subdomain prefix**: Use a specific subdomain for verification (e.g., TXT record on `_gondulf.example.com`)
|
||||
|
||||
The direct approach seems simpler but has significant drawbacks:
|
||||
- Conflicts with existing TXT records (SPF, DKIM, DMARC, domain verification for other services)
|
||||
- Clutters the main domain's DNS records
|
||||
- Makes it harder to identify which TXT record is for which service
|
||||
- Some DNS providers limit the number of TXT records on the root domain
|
||||
|
||||
The subdomain approach is widely used by major services:
|
||||
- Google uses `_domainkey` for DKIM
|
||||
- Various services use `_acme-challenge` for Let's Encrypt domain validation
|
||||
- GitHub uses `_github-challenge` for domain verification
|
||||
- Many OAuth/OIDC providers use service-specific prefixes
|
||||
|
||||
## Decision
|
||||
|
||||
We will use the subdomain prefix approach with `_gondulf.{domain}` for DNS TXT record verification.
|
||||
|
||||
The TXT record requirements:
|
||||
- **Location**: `_gondulf.{domain}` (e.g., `_gondulf.example.com`)
|
||||
- **Value**: `gondulf-verify-domain`
|
||||
- **Type**: TXT record
|
||||
|
||||
This approach follows industry best practices and RFC conventions for using underscore-prefixed subdomains for protocol-specific purposes.
|
||||
|
||||
## Consequences
|
||||
|
||||
### Positive Consequences
|
||||
|
||||
1. **No Conflicts**: Won't interfere with existing TXT records on the main domain
|
||||
2. **Clear Purpose**: The `_gondulf` prefix clearly identifies this as Gondulf-specific
|
||||
3. **Industry Standard**: Follows the same pattern as DKIM, ACME, and other protocols
|
||||
4. **Clean DNS**: Keeps the main domain's DNS records uncluttered
|
||||
5. **Multiple Services**: Users can have multiple IndieAuth servers verified without conflicts
|
||||
6. **Easy Removal**: Users can easily identify and remove Gondulf verification when needed
|
||||
|
||||
### Negative Consequences
|
||||
|
||||
1. **Slightly More Complex**: Users must understand subdomain DNS records (though this is standard)
|
||||
2. **Documentation Critical**: Must clearly document the exact subdomain format
|
||||
3. **DNS Propagation**: Subdomain records may propagate differently than root domain records
|
||||
4. **Wildcard Conflicts**: May conflict with wildcard DNS records (though underscore prefix minimizes this)
|
||||
|
||||
### Implementation Considerations
|
||||
|
||||
1. **Clear Instructions**: The error messages and documentation must clearly show `_gondulf.{domain}` format
|
||||
2. **DNS Query Logic**: The code must prefix the domain with `_gondulf.` before querying
|
||||
3. **Validation**: Must handle cases where users accidentally set the record on the wrong location
|
||||
4. **Debugging**: Logs should clearly show which domain was queried to aid troubleshooting
|
||||
|
||||
## Alternative Considered
|
||||
|
||||
**Direct TXT on root domain** was considered but rejected due to:
|
||||
- High likelihood of conflicts with existing TXT records
|
||||
- Poor service isolation
|
||||
- Difficulty in identifying ownership of TXT records
|
||||
- Goes against industry best practices
|
||||

||||

# ADR-012: Client ID Validation Compliance
|
||||
|
||||
Date: 2025-11-24
|
||||
|
||||
## Status
|
||||
|
||||
Accepted
|
||||
|
||||
## Context
|
||||
|
||||
During pre-release compliance review, we discovered that Gondulf's client_id validation is not fully compliant with the W3C IndieAuth specification Section 3.2. The current implementation in `normalize_client_id()` only performs basic HTTPS validation and port normalization, missing several critical requirements:
|
||||
|
||||
**Non-compliance issues identified:**
|
||||
1. Rejects HTTP URLs even for localhost (spec allows HTTP for loopback addresses)
|
||||
2. Accepts fragments in URLs (spec explicitly forbids fragments)
|
||||
3. Accepts username/password in URLs (spec forbids user info components)
|
||||
4. Accepts non-loopback IP addresses (spec only allows 127.0.0.1 and [::1])
|
||||
5. Accepts path traversal segments (. and ..)
|
||||
6. Does not normalize hostnames to lowercase
|
||||
7. Does not ensure path component exists
|
||||
|
||||
These violations could lead to:
|
||||
- Legitimate local development clients being rejected (HTTP localhost)
|
||||
- Security vulnerabilities (credential exposure, path traversal)
|
||||
- Interoperability issues with compliant IndieAuth clients
|
||||
- Confusion about client identity (fragments, case sensitivity)
|
||||
|
||||
## Decision
|
||||
|
||||
We will implement complete W3C IndieAuth specification compliance for client_id validation by:
|
||||
|
||||
1. **Separating validation from normalization**: Create a new `validate_client_id()` function that performs all specification checks, separate from the normalization logic.
|
||||
|
||||
2. **Supporting HTTP for localhost**: Allow HTTP scheme for localhost, 127.0.0.1, and [::1] to support local development while maintaining HTTPS requirement for production domains.
|
||||
|
||||
3. **Rejecting non-compliant URLs**: Explicitly reject URLs with fragments, credentials, non-loopback IPs, and path traversal segments.
|
||||
|
||||
4. **Providing specific error messages**: Return detailed error messages for each validation failure to help developers understand what needs to be fixed.
|
||||
|
||||
5. **Maintaining backward compatibility**: The stricter validation only rejects URLs that were already non-compliant with the specification. Valid client_ids continue to work.
|
||||
|
||||
## Consequences
|
||||
|
||||
### Positive Consequences
|
||||
|
||||
1. **Full specification compliance**: Gondulf will correctly handle all client_ids as defined by W3C IndieAuth specification.
|
||||
|
||||
2. **Improved security**: Rejecting credentials, path traversal, and non-loopback IPs prevents potential security vulnerabilities.
|
||||
|
||||
3. **Better developer experience**: Clear error messages help developers quickly fix client_id issues.
|
||||
|
||||
4. **Local development support**: HTTP localhost support enables easier local testing and development.
|
||||
|
||||
5. **Interoperability**: Any compliant IndieAuth client will work with Gondulf.
|
||||
|
||||
### Negative Consequences
|
||||
|
||||
1. **Breaking change for non-compliant clients**: Clients using non-compliant client_ids (e.g., with fragments or credentials) will be rejected. However, these were already violating the specification.
|
||||
|
||||
2. **Slightly more complex validation**: The validation logic is more comprehensive, but this complexity is contained within well-documented functions.
|
||||
|
||||
3. **Additional testing burden**: More test cases are needed to cover all validation rules.
|
||||
|
||||
### Implementation Notes
|
||||
|
||||
- The validation logic is implemented as a pure function with no side effects
|
||||
- Normalization happens after validation to ensure only valid client_ids are normalized
|
||||
- Both authorization and token endpoints use the same validation logic
|
||||
- Error messages follow OAuth 2.0 error response format
|
||||
|
||||
This decision ensures Gondulf is a fully compliant IndieAuth server that can interoperate with any specification-compliant client while maintaining security and providing a good developer experience.

# Client ID Validation Compliance
|
||||
|
||||
## Purpose
|
||||
|
||||
This design addresses critical non-compliance issues in Gondulf's client_id validation that violate the W3C IndieAuth specification Section 3.2. These issues must be fixed before v1.0.0 release to ensure any compliant IndieAuth client can successfully authenticate.
|
||||
|
||||
## CLARIFICATIONS (2025-11-24)
|
||||
|
||||
Based on Developer questions, the following clarifications have been added:
|
||||
|
||||
1. **IPv6 Bracket Handling**: Python's `urlparse` returns `hostname` WITHOUT brackets for IPv6 addresses. The brackets are only in `netloc`. Therefore, the check should be against '::1' without brackets.
|
||||
|
||||
2. **Normalization of IPv6 with Port**: When reconstructing URLs with IPv6 addresses and ports, brackets MUST be added back (e.g., `[::1]:8080`).
|
||||
|
||||
3. **Empty Path Normalization**: Confirmed - `https://example.com` should normalize to `https://example.com/` (with trailing slash).
|
||||
|
||||
4. **Validation Rule Ordering**: Implementation should follow the logical flow shown in the example implementation (lines 87-138), not the numbered list order. The try/except for URL parsing serves as the "Basic URL Structure" check.
|
||||
|
||||
5. **Endpoint Updates**: These are SEPARATE tasks and should NOT be implemented as part of the validation.py update task.
|
||||
|
||||
6. **Test File Location**: Tests should go in the existing `/home/phil/Projects/Gondulf/tests/unit/test_validation.py` file.
|
||||
|
||||
7. **Import Location**: The `ipaddress` import should be at module level (Python convention), not inside the function.
|
||||
|
||||
## Specification References
|
||||
|
||||
- **Primary**: [W3C IndieAuth Section 3.2 - Client Identifier](https://www.w3.org/TR/indieauth/#client-identifier)
|
||||
- **OAuth 2.0**: [RFC 6749 Section 2.2](https://datatracker.ietf.org/doc/html/rfc6749#section-2.2)
|
||||
- **Reference Implementation**: IndieLogin.com `/app/Authenticate.php`
|
||||
|
||||
## Design Overview
|
||||
|
||||
Replace the current incomplete `normalize_client_id()` function with two distinct functions:
|
||||
1. `validate_client_id()` - Validates client_id against all specification requirements
|
||||
2. `normalize_client_id()` - Normalizes a valid client_id to canonical form
|
||||
|
||||
This separation ensures clear validation logic and proper error reporting while maintaining backward compatibility with existing code that expects normalization.
|
||||
|
||||
## Component Details
|
||||
|
||||
### New Function: validate_client_id()
|
||||
|
||||
**Location**: `/home/phil/Projects/Gondulf/src/gondulf/utils/validation.py`
|
||||
|
||||
**Purpose**: Validate a client_id URL against all W3C IndieAuth specification requirements.
|
||||
|
||||
**Function Signature**:
|
||||
```python
|
||||
def validate_client_id(client_id: str) -> tuple[bool, str]:
|
||||
"""
|
||||
Validate client_id against W3C IndieAuth specification Section 3.2.
|
||||
|
||||
Args:
|
||||
client_id: The client identifier URL to validate

||||
|
||||
Returns:
|
||||
Tuple of (is_valid, error_message)
|
||||
- is_valid: True if client_id is valid, False otherwise
|
||||
- error_message: Empty string if valid, specific error message if invalid
|
||||
"""
|
||||
```
|
||||
|
||||
**Validation Rules** (in order):
|
||||
|
||||
1. **Basic URL Structure**
|
||||
- Must be a parseable URL with urlparse()
|
||||
- Error: "client_id must be a valid URL"
|
||||
|
||||
2. **Scheme Validation**
|
||||
- Must be 'https' OR 'http'
|
||||
- Error: "client_id must use https or http scheme"
|
||||
|
||||
3. **HTTP Scheme Restriction**
|
||||
- If scheme is 'http', hostname MUST be one of: 'localhost', '127.0.0.1', '::1' (note: hostname from urlparse has no brackets)
|
||||
- Error: "client_id with http scheme is only allowed for localhost, 127.0.0.1, or [::1]"
|
||||
|
||||
4. **Fragment Rejection**
|
||||
- Must NOT contain a fragment component (# part)
|
||||
- Error: "client_id must not contain a fragment (#)"
|
||||
|
||||
5. **User Info Rejection**
|
||||
- Must NOT contain username or password components
|
||||
- Error: "client_id must not contain username or password"
|
||||
|
||||
6. **IP Address Validation**
|
||||
- Check if hostname is an IP address using ipaddress.ip_address()
|
||||
- If it's an IP:
|
||||
- Must be loopback (127.0.0.1 or ::1)
|
||||
- Error: "client_id must not use IP address (except 127.0.0.1 or [::1])"
|
||||
- If not an IP (ValueError), it's a domain name (valid)
|
||||
|
||||
7. **Path Component Requirement**
|
||||
- Path must exist (at minimum "/")
|
||||
- If empty path, it's still valid (will be normalized to "/" later)
|
||||
|
||||
8. **Path Segment Validation**
|
||||
- Split path by '/' and check segments
|
||||
- Must NOT contain single dot ('.') as a complete segment
|
||||
- Must NOT contain double dot ('..') as a complete segment
|
||||
- Note: './file' or '../file' as part of a segment is allowed, only standalone '.' or '..' segments are rejected
|
||||
- Error: "client_id must not contain single-dot (.) or double-dot (..) path segments"
|
||||
|
||||
**Implementation**:
|
||||
```python

|
||||
def validate_client_id(client_id: str) -> tuple[bool, str]:

### Updated Function: normalize_client_id()
|
||||
|
||||
**Purpose**: Normalize a valid client_id to canonical form. Must validate first.

||||
|
||||
**Function Signature**:
|
||||
```python
|
||||
def normalize_client_id(client_id: str) -> str:

||||
Normalize client_id URL to canonical form per IndieAuth spec.
|

|
||||
Normalization rules:
|
||||
- Validate against specification first
|
||||
- Convert hostname to lowercase
|
||||
- Remove default ports (80 for http, 443 for https)
|
||||
- Ensure path exists (default to "/" if empty)
|
||||
- Preserve query string if present
|
||||
- Never include fragments (already validated out)

||||
|
||||
Args:
|
||||
client_id: Client ID URL to normalize

|
||||
Raises:
|
||||
ValueError: If client_id is not valid per specification
|
||||
"""
|
||||
```
|
||||
|
||||
**Normalization Rules**:
|
||||
|
||||
1. **Validation First**
|
||||
- Call validate_client_id()
|
||||
- If invalid, raise ValueError with the error message
|
||||
|
||||
2. **Hostname Normalization**
|
||||
- Convert hostname to lowercase
|
||||
- Preserve IPv6 brackets if present
|
||||
|
||||
3. **Port Normalization**
|
||||
- Remove port 80 for http URLs
|
||||
- Remove port 443 for https URLs
|
||||
- Preserve any other ports
|
||||
|
||||
4. **Path Normalization**
|
||||
- If path is empty, set to "/"
|
||||
- Do NOT remove trailing slashes (spec doesn't require this)
|
||||
- Do NOT normalize . or .. (already validated out)
|
||||
|
||||
5. **Component Assembly**
|
||||
- Reconstruct URL with normalized components
|
||||
- Include query string if present
|

### Authorization Endpoint Updates (SEPARATE TASK)
|
||||
|
||||
**NOTE**: This is a SEPARATE task and should NOT be implemented as part of the validation.py update task.
|
||||
|
||||
**Location**: `/home/phil/Projects/Gondulf/src/gondulf/endpoints/authorization.py`
|
||||
|
||||
When this separate task is implemented, update the authorization endpoint to use the new validation:
|
||||
|
||||
```python
|
||||
# In the authorize() function, when validating client_id:
|
||||
|
||||
# Validate and normalize client_id
|
||||
is_valid, error = validate_client_id(client_id)
|
||||
if not is_valid:
|
||||
# Return error to client
|
||||
return authorization_error_response(
|
||||
redirect_uri=redirect_uri,
|
||||
error="invalid_request",
|
||||
error_description=f"Invalid client_id: {error}",
|
||||
state=state
|
||||
)
|
||||
|
||||
# Normalize for consistent storage/comparison
|
||||
try:
|
||||
normalized_client_id = normalize_client_id(client_id)
|
||||
except ValueError as e:
|
||||
# This shouldn't happen if validate_client_id passed, but handle it
|
||||
return authorization_error_response(
|
||||
redirect_uri=redirect_uri,
|
||||
error="invalid_request",
|
||||
error_description=str(e),
|
||||
state=state
|
||||
)
|
||||
```
|
||||
|
||||
### Token Endpoint Updates (SEPARATE TASK)
|
||||
|
||||
**NOTE**: This is a SEPARATE task and should NOT be implemented as part of the validation.py update task.
|
||||
|
||||
**Location**: `/home/phil/Projects/Gondulf/src/gondulf/endpoints/token.py`
|
||||
|
||||
When this separate task is implemented, update token endpoint validation similarly:
|
||||
|
||||
```python
|
||||
# In the token() function, when validating client_id:
|
||||
|
||||
# Validate and normalize client_id
|
||||
is_valid, error = validate_client_id(client_id)
|
||||
if not is_valid:
|
||||
return JSONResponse(
|
||||
status_code=400,
|
||||
content={
|
||||
"error": "invalid_client",
|
||||
"error_description": f"Invalid client_id: {error}"
|
||||
}
|
||||
)
|
||||
|
||||
# Normalize for comparison with stored value
|
||||
normalized_client_id = normalize_client_id(client_id)
|
||||
```
|
||||
|
||||
## Data Models
|
||||
|
||||
No database schema changes required. The validation happens at the API layer before storage.
|
||||
|
||||
## API Contracts
|
||||
|
||||
### Error Responses
|
||||
|
||||
When client_id validation fails, return appropriate OAuth 2.0 error responses:
|
||||
|
||||
**Authorization Endpoint** (if redirect_uri is valid):
|
||||
```
|
||||
HTTP/1.1 302 Found
|
||||
Location: {redirect_uri}?error=invalid_request&error_description=Invalid+client_id%3A+{specific_error}&state={state}
|
||||
```
|
||||
|
||||
**Authorization Endpoint** (if redirect_uri is also invalid):
|
||||
```
|
||||
HTTP/1.1 400 Bad Request
|
||||
Content-Type: text/html
|
||||
|
||||
<html>
|
||||
<body>
|
||||
<h1>Invalid Request</h1>
|
||||
<p>Invalid client_id: {specific_error}</p>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
**Token Endpoint**:
|
||||
```
|
||||
HTTP/1.1 400 Bad Request
|
||||
Content-Type: application/json
|
||||
|
||||
{
|
||||
"error": "invalid_client",
|
||||
"error_description": "Invalid client_id: {specific_error}"
|
||||
}
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
### Validation Error Messages
|
||||
|
||||
Each validation rule has a specific, user-friendly error message:
|
||||
|
||||
| Validation Rule | Error Message |
|
||||
|-----------------|---------------|
|
||||
| Invalid URL | "client_id must be a valid URL: {parse_error}" |
|
||||
| Wrong scheme | "client_id must use https or http scheme" |
|
||||
| HTTP not localhost | "client_id with http scheme is only allowed for localhost, 127.0.0.1, or [::1]" |
|
||||
| Has fragment | "client_id must not contain a fragment (#)" |
|
||||
| Has credentials | "client_id must not contain username or password" |
|
||||
| Non-loopback IP | "client_id must not use IP address (except 127.0.0.1 or [::1])" |
|
||||
| Path traversal | "client_id must not contain single-dot (.) or double-dot (..) path segments" |
|
||||
|
||||
### Exception Handling
|
||||
|
||||
- `validate_client_id()` never raises exceptions, returns (False, error_message)
|
||||
- `normalize_client_id()` raises ValueError if validation fails
|
||||
- URL parsing exceptions are caught and converted to validation errors
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Fragment Rejection
|
||||
Fragments in client_ids could cause confusion about the actual client identity. By rejecting them, we ensure clear client identification.
|
||||
|
||||
### Credential Rejection
|
||||
Username/password in URLs could leak into logs or be displayed to users. Rejecting them prevents credential exposure.
|
||||
|
||||
### IP Address Restriction
|
||||
Allowing arbitrary IP addresses could bypass domain-based security controls. Only loopback addresses are permitted for local development.
|
||||
|
||||
### Path Traversal Prevention
|
||||
Single-dot and double-dot segments could potentially be used for path traversal attacks or cause confusion about the client's identity.
|
||||
|
||||
### HTTP Localhost Support
|
||||
HTTP is only allowed for localhost/loopback addresses to support local development while maintaining security in production.
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Unit Tests Required
|
||||
|
||||
Create comprehensive tests in `/home/phil/Projects/Gondulf/tests/unit/test_validation.py`:
|
||||
|
||||
#### Valid Client IDs
|
||||
```python
|
||||
valid_client_ids = [
|
||||
"https://example.com",
|
||||
"https://example.com/",
|
||||
"https://example.com/app",
|
||||
"https://example.com/app/client",
|
||||
"https://example.com?foo=bar",
|
||||
"https://example.com/app?foo=bar&baz=qux",
|
||||
"https://sub.example.com",
|
||||
"https://example.com:8080",
|
||||
"https://example.com:8080/app",
|
||||
"http://localhost",
|
||||
"http://localhost:3000",
|
||||
"http://127.0.0.1",
|
||||
"http://127.0.0.1:8080",
|
||||
"http://[::1]",
|
||||
"http://[::1]:8080",
|
||||
]
|
||||
```
|
||||
|
||||
#### Invalid Client IDs
|
||||
```python
|
||||
invalid_client_ids = [
|
||||
("ftp://example.com", "must use https or http scheme"),
|
||||
("https://example.com#fragment", "must not contain a fragment"),
|
||||
("https://user:pass@example.com", "must not contain username or password"),
|
||||
("https://example.com/./invalid", "must not contain single-dot"),
|
||||
("https://example.com/../invalid", "must not contain double-dot"),
|
||||
("http://example.com", "http scheme is only allowed for localhost"),
|
||||
("https://192.168.1.1", "must not use IP address"),
|
||||
("https://10.0.0.1", "must not use IP address"),
|
||||
("https://[2001:db8::1]", "must not use IP address"),
|
||||
("not-a-url", "must be a valid URL"),
|
||||
("", "must be a valid URL"),
|
||||
]
|
||||
```
|
||||
|
||||
#### Normalization Tests
|
||||
```python
|
||||
normalization_cases = [
|
||||
("HTTPS://EXAMPLE.COM", "https://example.com/"),
|
||||
("https://example.com", "https://example.com/"),
|
||||
("https://example.com:443", "https://example.com/"),
|
||||
("http://localhost:80", "http://localhost/"),
|
||||
("https://EXAMPLE.COM:443/app", "https://example.com/app"),
|
||||
("https://Example.Com/APP", "https://example.com/APP"), # Path case preserved
|
||||
("https://example.com?foo=bar", "https://example.com/?foo=bar"),
|
||||
]
|
||||
```
|
||||
|
||||
### Integration Tests
|
||||
|
||||
1. Test authorization endpoint with various client_ids
|
||||
2. Test token endpoint with various client_ids
|
||||
3. Test that normalized client_ids match correctly between endpoints
|
||||
4. Test error responses for invalid client_ids
|
||||
|
||||
### Security Tests
|
||||
|
||||
1. Test that fragments are always rejected
|
||||
2. Test that credentials are always rejected
|
||||
3. Test that non-loopback IPs are rejected
|
||||
4. Test that path traversal segments are rejected
|
||||
5. Test that HTTP is only allowed for localhost
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
1. ✅ All valid client_ids per W3C specification are accepted
|
||||
2. ✅ All invalid client_ids per W3C specification are rejected with specific error messages

|
||||
11. ✅ Empty paths are normalized to "/"
|
||||
12. ✅ Query strings are preserved
|
||||
13. ✅ Authorization endpoint uses new validation

|
||||
|
||||
## Implementation Order
|
||||
|
||||
### Current Task (validation.py update):
|
||||
1. Implement `validate_client_id()` function in validation.py
|
||||
2. Update `normalize_client_id()` to use validation in validation.py
|
||||
3. Write comprehensive unit tests in tests/unit/test_validation.py
|
||||
|
||||
### Separate Future Tasks:
|
||||
4. Update authorization endpoint (SEPARATE TASK)
|
||||
5. Update token endpoint (SEPARATE TASK)
|
||||
6. Write integration tests (SEPARATE TASK)
|
||||
7. Test with real IndieAuth clients (SEPARATE TASK)
|
||||
|
||||
## Migration Notes
|
||||
|
||||
- No database migration needed
|
||||
- Existing stored client_ids remain valid (they were normalized on storage)
|
||||
- New validation is stricter but backward compatible with valid client_ids

# DNS Verification Bug Fix Design
|
||||
|
||||
## Purpose
|
||||
Fix critical bug in DNS TXT record verification where the code queries the wrong domain location, preventing successful domain verification even when users have correctly configured their DNS records.
|
||||
|
||||
## Problem Statement
|
||||
|
||||
### Current Incorrect Behavior
|
||||
The DNS verification service currently queries the wrong domain for TXT records:
|
||||
|
||||
1. **User instructions** (correctly shown in template): Set TXT record at `_gondulf.{domain}`
|
||||
2. **User action**: Creates TXT record at `_gondulf.thesatelliteoflove.com` with value `gondulf-verify-domain`
|
||||
3. **Code behavior** (INCORRECT): Queries `thesatelliteoflove.com` instead of `_gondulf.thesatelliteoflove.com`
|
||||
4. **Result**: Verification always fails
|
||||
|
||||
### Root Cause
|
||||
In `src/gondulf/dns.py`, the `verify_txt_record` method passes the domain directly to `get_txt_records`, which then queries that exact domain. The calling code in `src/gondulf/routers/authorization.py` also passes just the base domain without the `_gondulf.` prefix.
|
||||
|
||||
## Design Overview
|
||||
|
||||
The fix requires modifying the DNS verification logic to correctly prefix the domain with `_gondulf.` when querying TXT records for Gondulf domain verification purposes.
|
||||
|
||||
## Component Details
|
||||
|
||||
### 1. DNSService Updates (`src/gondulf/dns.py`)
|
||||
|
||||
#### Option A: Modify `verify_txt_record` Method (RECOMMENDED)
|
||||
Update the `verify_txt_record` method to handle Gondulf-specific verification by prefixing the domain:
|
||||
|
||||
```python
|
||||
def verify_txt_record(self, domain: str, expected_value: str) -> bool:
|
||||
"""
|
||||
Verify that domain has a TXT record with the expected value.
|
||||
|
||||
For Gondulf domain verification (expected_value="gondulf-verify-domain"),
|
||||
queries the _gondulf.{domain} subdomain as per specification.
|
||||
|
||||
Args:
|
||||
domain: Domain name to verify (e.g., "example.com")
|
||||
expected_value: Expected TXT record value
|
||||
|
||||
Returns:
|
||||
True if expected value found in TXT records, False otherwise
|
||||
"""
|
||||
try:
|
||||
# For Gondulf domain verification, query _gondulf subdomain
|
||||
if expected_value == "gondulf-verify-domain":
|
||||
query_domain = f"_gondulf.{domain}"
|
||||
else:
|
||||
query_domain = domain
|
||||
|
||||
txt_records = self.get_txt_records(query_domain)
|
||||
|
||||
# Check if expected value is in any TXT record
|
||||
for record in txt_records:
|
||||
if expected_value in record:
|
||||
logger.info(
|
||||
f"TXT record verification successful for domain={domain} "
|
||||
f"(queried {query_domain})"
|
||||
)
|
||||
return True
|
||||
|
||||
logger.debug(
|
||||
f"TXT record verification failed: expected value not found "
|
||||
f"for domain={domain} (queried {query_domain})"
|
||||
)
|
||||
return False
|
||||
|
||||
except DNSError as e:
|
||||
logger.warning(f"TXT record verification failed for domain={domain}: {e}")
|
||||
return False
|
||||
```
|
||||
|
||||
#### Option B: Create Dedicated Method (ALTERNATIVE - NOT RECOMMENDED)
|
||||
Add a new method specifically for Gondulf verification:
|
||||
|
||||
```python
|
||||
def verify_gondulf_domain(self, domain: str) -> bool:
|
||||
"""
|
||||
Verify Gondulf domain ownership via TXT record at _gondulf.{domain}.
|
||||
|
||||
Args:
|
||||
domain: Domain name to verify (e.g., "example.com")
|
||||
|
||||
Returns:
|
||||
True if gondulf-verify-domain found in _gondulf.{domain} TXT records
|
||||
"""
|
||||
gondulf_subdomain = f"_gondulf.{domain}"
|
||||
return self.verify_txt_record(gondulf_subdomain, "gondulf-verify-domain")
|
||||
```
|
||||
|
||||
**Recommendation**: Use Option A. It keeps the fix localized to the DNS service and maintains backward compatibility while fixing the bug with minimal changes.
|
||||
|
||||
### 2. No Changes Required in Authorization Router
|
||||
|
||||
With Option A, no changes are needed in `src/gondulf/routers/authorization.py` since the fix is entirely contained within the DNS service. The existing call remains correct:
|
||||
|
||||
```python
|
||||
dns_verified = dns_service.verify_txt_record(domain, "gondulf-verify-domain")
|
||||
```
|
||||
|
||||
### 3. Template Remains Correct
|
||||
|
||||
The template (`src/gondulf/templates/verification_error.html`) already shows the correct instructions and needs no changes.
|
||||
|
||||
## Data Models
|
||||
|
||||
No data model changes required.
|
||||
|
||||
## API Contracts
|
||||
|
||||
No API changes required. This is an internal bug fix.
|
||||
|
||||
## Error Handling
|
||||
|
||||
### DNS Query Errors
|
||||
The existing error handling in `get_txt_records` is sufficient:
|
||||
- NXDOMAIN: Domain doesn't exist (including subdomain)
|
||||
- NoAnswer: No TXT records found
|
||||
- Timeout: DNS server timeout
|
||||
- Other DNS exceptions: General failure
|
||||
|
||||
All these cases correctly return False for verification failure.
|
||||
|
||||
### Logging Updates
|
||||
Update log messages to include which domain was actually queried:
|
||||
- Success: Include both the requested domain and the queried domain
|
||||
- Failure: Include both domains to aid debugging
|
||||
|
||||
## Security Considerations
|
||||
|
||||
1. **No New Attack Vectors**: The fix doesn't introduce new security concerns
|
||||
2. **DNS Rebinding**: Not applicable (we're only reading TXT records)
|
||||
3. **Cache Poisoning**: Existing DNS resolver safeguards apply
|
||||
4. **Subdomain Takeover**: The `_gondulf` prefix is specifically chosen to avoid conflicts
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Unit Tests Required
|
||||
|
||||
1. **Test Gondulf domain verification with correct TXT record**
|
||||
- Mock DNS response for `_gondulf.example.com` with value `gondulf-verify-domain`
|
||||
- Verify `verify_txt_record("example.com", "gondulf-verify-domain")` returns True
|
||||
|
||||
2. **Test Gondulf domain verification with missing TXT record**
|
||||
- Mock DNS response for `_gondulf.example.com` with no TXT records
|
||||
- Verify `verify_txt_record("example.com", "gondulf-verify-domain")` returns False
|
||||
|
||||
3. **Test Gondulf domain verification with wrong TXT value**
|
||||
- Mock DNS response for `_gondulf.example.com` with value `wrong-value`
|
||||
- Verify `verify_txt_record("example.com", "gondulf-verify-domain")` returns False
|
||||
|
||||
4. **Test non-Gondulf TXT verification still works**
|
||||
- Mock DNS response for `example.com` (not prefixed) with value `other-value`
|
||||
- Verify `verify_txt_record("example.com", "other-value")` returns True
|
||||
- Ensures backward compatibility for any other TXT verification uses
|
||||
|
||||
5. **Test NXDOMAIN handling**
|
||||
- Mock NXDOMAIN for `_gondulf.example.com`
|
||||
- Verify `verify_txt_record("example.com", "gondulf-verify-domain")` returns False
|
||||
|
||||
### Integration Test
|
||||
|
||||
1. **End-to-end authorization flow test**
|
||||
- Set up test domain with `_gondulf.{domain}` TXT record
|
||||
- Attempt authorization flow
|
||||
- Verify DNS verification passes
|
||||
|
||||
### Manual Testing
|
||||
|
||||
1. Configure real DNS record: `_gondulf.yourdomain.com` with value `gondulf-verify-domain`
|
||||
2. Test authorization flow
|
||||
3. Verify successful DNS verification
|
||||
4. Check logs show correct domain being queried
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
1. ✅ DNS verification queries `_gondulf.{domain}` when verifying Gondulf domain ownership
|
||||
2. ✅ Users with correctly configured TXT records can successfully verify their domain
|
||||
3. ✅ Log messages clearly show which domain was queried for debugging
|
||||
4. ✅ Non-Gondulf TXT verification (if used elsewhere) continues to work
|
||||
5. ✅ All existing tests pass
|
||||
6. ✅ New unit tests cover the fix
|
||||
7. ✅ Manual testing confirms real DNS records work
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
1. **Critical Bug**: This is a P0 bug that completely breaks domain verification
|
||||
2. **Simple Fix**: The fix is straightforward - just add the prefix when appropriate
|
||||
3. **Test Thoroughly**: While the fix is simple, ensure comprehensive testing
|
||||
4. **Verify Logs**: Update logging to be clear about what domain is being queried
|
||||
|
||||
## Migration Considerations
|
||||
|
||||
None required. This is a bug fix that makes the code work as originally intended. No database migrations or data changes needed.

## Security Considerations
|
||||
|
||||
### During Testing
|
||||
1. **Use Production Domain**: Test with actual domain, not localhost
|
||||
2. **Monitor Logs**: Watch for any security warnings
|
||||
3. **Check Headers**: Verify security headers on all responses
|
||||
4. **Test HTTPS**: Ensure no HTTP fallback
|
||||
|
||||
### Post-Testing
|
||||
1. **Review Logs**: Check for any suspicious activity
|
||||
2. **Rotate Secrets**: If any were exposed during testing
|
||||
3. **Document Issues**: Any security concerns found
|
||||
|
||||
## Rollback Plan
|
||||
|
||||
If critical issues found during testing:
|
||||
|
||||
1. **Immediate Response**
|
||||
- Document exact failure
|
||||
- Capture all logs
|
||||
- Screenshot error states
|
||||
|
||||
2. **Assessment**
|
||||
- Determine if issue is:
|
||||
- Configuration (fix without code change)
|
||||
- Minor bug (rc.9 candidate)
|
||||
- Major issue (requires design review)
|
||||
|
||||
3. **Action**
|
||||
- Configuration: Fix and retest
|
||||
- Minor bug: Create fix design, implement rc.9
|
||||
- Major issue: Halt release, return to design phase
|
||||
|
||||
## Success Metrics

|
||||
- Verify backup working
|
||||
|
||||
### First Week
|
||||
- Track authentication success rate
|
||||
- Collect client compatibility reports
|
||||
- Document any new issues
|
||||
- Plan v1.1.0 features
|
||||
|
||||
### First Month
|
||||
- Analyze usage patterns

# Implementation Report: DNS Verification Bug Fix
|
||||
|
||||
**Date**: 2025-11-22
|
||||
**Developer**: Claude (Developer Agent)
|
||||
**Design Reference**: /docs/designs/dns-verification-bug-fix.md
|
||||
|
||||
## Summary
|
||||
|
||||
Fixed a critical bug in the DNS TXT record verification that caused domain verification to always fail. The code was querying the base domain (e.g., `example.com`) instead of the `_gondulf.{domain}` subdomain (e.g., `_gondulf.example.com`) where users are instructed to place their TXT records. The fix modifies the `verify_txt_record` method in `src/gondulf/dns.py` to prefix the domain with `_gondulf.` when the expected value is `gondulf-verify-domain`. All tests pass with 100% coverage on the DNS module.
|
||||
|
||||
## What Was Implemented
|
||||
|
||||
### Components Modified
|
||||
|
||||
1. **`src/gondulf/dns.py`** - DNSService class
|
||||
- Modified `verify_txt_record` method to query the correct subdomain
|
||||
- Updated docstring to document the Gondulf-specific behavior
|
||||
- Updated all logging statements to include both the requested domain and the queried domain
|
||||
|
||||
2. **`tests/unit/test_dns.py`** - DNS unit tests
|
||||
- Added new test class `TestGondulfDomainVerification` with 7 test cases
|
||||
- Tests verify the critical bug fix behavior
|
||||
- Tests ensure backward compatibility for non-Gondulf TXT verification
|
||||
|
||||
### Key Implementation Details
|
||||
|
||||
The fix implements Option A from the design document - modifying the existing `verify_txt_record` method rather than creating a new dedicated method. This keeps the fix localized and maintains backward compatibility.
|
||||
|
||||
**Core logic added:**
|
||||
```python
|
||||
# For Gondulf domain verification, query _gondulf subdomain
|
||||
if expected_value == "gondulf-verify-domain":
|
||||
query_domain = f"_gondulf.{domain}"
|
||||
else:
|
||||
query_domain = domain
|
||||
```
|
||||
|
||||
**Logging updates:**
|
||||
- Success log now shows: `"TXT record verification successful for domain={domain} (queried {query_domain})"`
|
||||
- Failure log now shows: `"TXT record verification failed: expected value not found for domain={domain} (queried {query_domain})"`
|
||||
- Error log now shows: `"TXT record verification failed for domain={domain} (queried {query_domain}): {e}"`
|
||||
|
||||
## How It Was Implemented
|
||||
|
||||
### Approach
|
||||
|
||||
1. **Reviewed design document** - Confirmed Option A (modify existing method) was the recommended approach
|
||||
2. **Reviewed standards** - Checked coding.md and testing.md for requirements
|
||||
3. **Implemented the fix** - Single edit to `verify_txt_record` method
|
||||
4. **Added comprehensive tests** - Created new test class covering all scenarios from design
|
||||
5. **Ran full test suite** - Verified no regressions
|
||||
|
||||
### Deviations from Design
|
||||
|
||||
No deviations from design.
|
||||
|
||||
The implementation follows the design document exactly:
|
||||
- Used Option A (modify `verify_txt_record` method)
|
||||
- Added the domain prefixing logic as specified
|
||||
- Updated logging to show both domains
|
||||
- No changes needed to authorization router or templates
|
||||
|
||||
## Issues Encountered
|
||||
|
||||
No significant issues encountered.
|
||||
|
||||
The fix was straightforward as designed. The existing code structure made the change clean and isolated.
|
||||
|
||||

### Test Scenarios
|
||||
|
||||
#### New Unit Tests Added (TestGondulfDomainVerification)
|
||||
|
||||
1. **test_gondulf_verification_queries_prefixed_subdomain** - Critical test verifying the bug fix
|
||||
- Verifies `verify_txt_record("example.com", "gondulf-verify-domain")` queries `_gondulf.example.com`
|
||||
|
||||
2. **test_gondulf_verification_with_missing_txt_record** - Tests NoAnswer handling
|
||||
- Verifies returns False when no TXT records exist at `_gondulf.{domain}`
|
||||
|
||||
3. **test_gondulf_verification_with_wrong_txt_value** - Tests value mismatch
|
||||
- Verifies returns False when TXT value doesn't match
|
||||
|
||||
4. **test_non_gondulf_verification_queries_base_domain** - Backward compatibility test
|
||||
- Verifies other TXT verification still queries base domain (not prefixed)
|
||||
|
||||
5. **test_gondulf_verification_with_nxdomain** - Tests NXDOMAIN handling
|
||||
- Verifies returns False when `_gondulf.{domain}` doesn't exist
|
||||
|
||||
6. **test_gondulf_verification_among_multiple_txt_records** - Tests multi-record scenarios
|
||||
- Verifies correct value found among multiple TXT records
|
||||
|
||||
7. **test_gondulf_verification_with_subdomain** - Tests subdomain handling
|
||||
- Verifies `blog.example.com` queries `_gondulf.blog.example.com`
|
||||
|
||||
#### Existing Tests (All Pass)
|
||||
|
||||
All 22 existing DNS tests continue to pass, confirming no regressions:
|
||||
- TestDNSServiceInit (1 test)
|
||||
- TestGetTxtRecords (7 tests)
|
||||
- TestVerifyTxtRecord (7 tests)
|
||||
- TestCheckDomainExists (5 tests)
|
||||
- TestResolverFallback (2 tests)
|
||||
|
||||
### Test Results Analysis
|
||||
|
||||
- All 29 DNS tests pass (22 existing + 7 new)
|
||||
- 100% coverage on dns.py module
|
||||
- Full test suite (487 tests) passes with no regressions
|
||||
- 5 skipped tests are unrelated (SQL injection tests awaiting implementation)
|
||||
- Deprecation warnings are unrelated to this change (FastAPI/Starlette lifecycle patterns)
|
||||
|
||||
## Technical Debt Created
|
||||
|
||||
No technical debt identified.
|
||||
|
||||
The fix is clean, well-tested, and follows the existing code patterns. The implementation matches the design exactly.
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Manual Testing** - Per the design document, manual testing with a real DNS record is recommended:
|
||||
- Configure real DNS record: `_gondulf.yourdomain.com` with value `gondulf-verify-domain`
|
||||
- Test authorization flow
|
||||
- Verify successful DNS verification
|
||||
- Check logs show correct domain being queried
|
||||
|
||||
2. **Deployment** - This is a P0 critical bug fix that should be deployed to production as soon as testing is complete.
|
||||

# Implementation Report: Client ID Validation Compliance
|
||||
|
||||
**Date**: 2025-11-24
|
||||
**Developer**: Developer Agent
|
||||
**Design Reference**: /home/phil/Projects/Gondulf/docs/designs/client-id-validation-compliance.md
|
||||
|
||||
## Summary
|
||||
|
||||
Successfully implemented W3C IndieAuth specification-compliant client_id validation in `/home/phil/Projects/Gondulf/src/gondulf/utils/validation.py`. Created new `validate_client_id()` function and updated `normalize_client_id()` to use proper validation. All 527 tests pass with 99% code coverage. Implementation is complete and ready for use.
|
||||
|
||||
## What Was Implemented
|
||||
|
||||
### Components Created
|
||||
|
||||
- **validate_client_id() function** in `/home/phil/Projects/Gondulf/src/gondulf/utils/validation.py`
|
||||
- Validates client_id URLs against W3C IndieAuth Section 3.2 requirements
|
||||
- Returns tuple of (is_valid, error_message) for precise error reporting
|
||||
- Handles all edge cases: schemes, fragments, credentials, IP addresses, path traversal
|
||||
|
||||
### Components Updated
|
||||
|
||||
- **normalize_client_id() function** in `/home/phil/Projects/Gondulf/src/gondulf/utils/validation.py`
|
||||
- Now validates client_id before normalization
|
||||
- Properly handles hostname lowercasing
|
||||
- Correctly normalizes default ports (80 for http, 443 for https)
|
||||
- Adds trailing slash when path is empty
|
||||
- Properly handles IPv6 addresses with bracket notation
|
||||
|
||||
- **Test suite** in `/home/phil/Projects/Gondulf/tests/unit/test_validation.py`
|
||||
- Added 31 new tests for validate_client_id()
|
||||
- Updated 23 tests for normalize_client_id()
|
||||
- Total of 75 validation tests, all passing
|
||||
|
||||
### Key Implementation Details
|
||||
|
||||
#### Validation Logic
|
||||
The `validate_client_id()` function implements the following validation sequence per the design:
|
||||
|
||||
1. **URL Parsing**: Uses try/except to catch malformed URLs
|
||||
2. **Scheme Validation**: Only accepts 'https' or 'http'
|
||||
3. **HTTP Restriction**: HTTP only allowed for localhost, 127.0.0.1, or ::1
|
||||
4. **Fragment Rejection**: Rejects URLs with fragment components
|
||||
5. **Credential Rejection**: Rejects URLs with username/password
|
||||
6. **IP Address Check**: Uses `ipaddress` module to detect and reject non-loopback IPs
|
||||
7. **Path Traversal Prevention**: Rejects single-dot (.) and double-dot (..) path segments
|
||||
|
||||
#### Normalization Logic
|
||||
The `normalize_client_id()` function:
|
||||
|
||||
- Calls `validate_client_id()` first, raising ValueError on invalid input
|
||||
- Lowercases hostnames using `parsed.hostname.lower()`
|
||||
- Detects IPv6 addresses by checking for ':' in hostname
|
||||
- Adds brackets around IPv6 addresses in the reconstructed URL
|
||||
- Removes default ports (80 for http, 443 for https)
|
||||
- Ensures path exists (defaults to "/" if empty)
|
||||
- Preserves query strings
|
||||
- Never includes fragments (already validated out)
|
||||
|
||||
#### IPv6 Handling
|
||||
The implementation correctly handles IPv6 bracket notation:
|
||||
- `urlparse()` returns IPv6 addresses WITHOUT brackets in `parsed.hostname`
|
||||
- Brackets must be added back when reconstructing URLs
|
||||
- Example: `http://[::1]:8080` → `parsed.hostname` = `'::1'` → reconstructed with brackets
|
||||
|
||||
## How It Was Implemented
|
||||
|
||||
### Approach
|
||||
|
||||
1. **Import Addition**: Added `ipaddress` module import at the top of validation.py
|
||||
2. **Function Creation**: Implemented `validate_client_id()` following the design's example implementation exactly
|
||||
3. **Function Update**: Replaced existing `normalize_client_id()` logic with new validation-first approach
|
||||
4. **Test Development**: Wrote comprehensive tests covering all valid and invalid cases from design
|
||||
5. **Test Execution**: Verified all tests pass and coverage remains high
|
||||
|
||||
### Design Adherence
|
||||
|
||||
The implementation follows the design document (with CLARIFICATIONS section) exactly:
|
||||
|
||||
- Used the provided function signatures verbatim
|
||||
- Implemented validation rules in the logical flow order (not the numbered list)
|
||||
- Used exact error messages specified in the design
|
||||
- Handled IPv6 addresses correctly per clarifications (hostname without brackets, URL with brackets)
|
||||
- Added trailing slash for empty paths as clarified
|
||||
- Used module-level import for `ipaddress` as clarified
|
||||
|
||||
### Deviations from Design
|
||||
|
||||
**No deviations from design.** The implementation follows the design specification and all clarifications exactly.
|
||||
|
||||
## Issues Encountered
|
||||
|
||||
### No Significant Issues
|
||||
|
||||
Implementation proceeded smoothly with no blockers or unexpected challenges. All clarifications had been resolved by the Architect before implementation began, allowing straightforward development.

|
||||
## Next Steps
|
||||
|
||||
This implementation completes the client_id validation compliance task. The Architect has identified that endpoint updates are SEPARATE tasks:
|
||||
|
||||
1. **Authorization endpoint update** (SEPARATE TASK) - Update `/home/phil/Projects/Gondulf/src/gondulf/endpoints/authorization.py` to use `validate_client_id()` and `normalize_client_id()`
|
||||
|
||||
2. **Token endpoint update** (SEPARATE TASK) - Update `/home/phil/Projects/Gondulf/src/gondulf/endpoints/token.py` to use `validate_client_id()` and `normalize_client_id()`
|
||||
|
||||
3. **Integration testing** (SEPARATE TASK) - Test the updated endpoints with real IndieAuth clients
|
||||
|
||||
The validation functions are ready for use by these future tasks.
