Pattern 1: Add null safety checks and default values when accessing potentially undefined values to prevent runtime errors. This includes checking for None values and providing fallback values when accessing dictionary keys or object attributes.
Example code before:
value = data['key']
result = obj.attribute
Example code after:
value = data.get('key', default_value)
result = getattr(obj, 'attribute', default_value)

Suggestion 1:
Handle missing score_why values safely
Ensure that suggestion['score_why'] is always defined and non-empty to prevent potential runtime errors when accessing it in the new code.
pr_agent/tools/pr_code_suggestions.py [798]
-pr_body += f"__\n\nWhy: {suggestion['score_why']}\n\n"
+pr_body += f"__\n\nWhy: {suggestion.get('score_why', 'No explanation provided')}\n\n"Suggestion 2:
Handle missing or invalid score values
Add a fallback mechanism for suggestion['score'] to handle cases where it might be missing or not convertible to an integer.
pr_agent/tools/pr_code_suggestions.py [804]
-score_int = int(suggestion['score'])
+score_int = int(suggestion.get('score', 0))Suggestion 3:
Handle missing score values safely
Handle potential None or non-integer score values before conversion to prevent runtime errors

Add null safety check
Add a null check for user_message_only_models before using it in the any() function to prevent potential NoneType errors if the setting is not defined.
pr_agent/algo/ai_handlers/litellm_ai_handler.py [201-202]

+user_message_only_models = get_settings().config.user_message_only_models or []
if user_message_only_models and any(entry in model for entry in user_message_only_models):Suggestion 5:
Add null check before string operations to prevent potential runtime errors
Add error handling for the case when response is empty or None before attempting string operations. The current implementation could raise AttributeError if response is None.
pr_agent/tools/pr_update_changelog.py [115-117]
+if not response:
+ return ""
response = response.strip()
if response.startswith("```"):
response_lines = response.splitlines()Pattern 2: Extract repeated code patterns into separate functions or constants to improve maintainability and reduce duplication, especially for commonly used operations or values.
Example code before:
if condition1:
return JSONResponse(status_code=200, content={"message": "success"})
if condition2:
return JSONResponse(status_code=200, content={"message": "success"})
Example code after:
SUCCESS_RESPONSE = JSONResponse(status_code=200, content={"message": "success"})
if condition1:
return SUCCESS_RESPONSE
if condition2:

Suggestion 1:
Extract draft MR skipping logic into a separate function to improve code organization
Consider extracting the logic for checking if a merge request is a draft and should be skipped into a separate function. This will improve code readability and reduce duplication.
pr_agent/servers/gitlab_webhook.py [133-135]
-if draft and skip_draft_mr:
- get_logger().info(f"Skipping draft MR: {url}")
- return JSONResponse(status_code=status.HTTP_200_OK, content=jsonable_encoder({"message": "success"}))
+if should_skip_draft_mr(draft, skip_draft_mr, url):
+ return SUCCESS_RESPONSE
Suggestion 2:
Use a constant for repeated success responses to improve code maintainability
Consider using a constant for the 'success' message to avoid repetition and improve maintainability. Define a constant at the module level and use it in all return statements.
pr_agent/servers/gitlab_webhook.py [124]
-return JSONResponse(status_code=status.HTTP_200_OK, content=jsonable_encoder({"message": "success"}))
+return SUCCESS_RESPONSE
Suggestion 3:
Extract repeated code into a separate function to reduce duplication
Consider extracting the repeated JSONResponse creation into a separate function to reduce code duplication and improve maintainability.
pr_agent/servers/gitlab_webhook.py [139-143]
+def create_success_response():
+ return JSONResponse(status_code=status.HTTP_200_OK, content=jsonable_encoder({"message": "success"}))

get_logger().info(f"New merge request: {url}")
await _perform_commands_gitlab("pr_commands", PRAgent(), url, log_context)
Suggestion 4:
Use a constant for the maximum number of previous comments instead of hardcoding the value
Consider using a constant or configuration variable for the maximum number of previous comments instead of hardcoding the value 4. This will make the code more flexible and easier to maintain.
pr_agent/tools/pr_code_suggestions.py [181-187]
+MAX_PREVIOUS_COMMENTS = 4 # Define this at the top of the file or in a config
+
def publish_persistent_comment_with_history(self, pr_comment: str,

update_header: bool = True,
name='review',
final_update_message=True,
- max_previous_comments=4,
+ max_previous_comments=MAX_PREVIOUS_COMMENTS,
progress_response=None):
Pattern 3: Use more efficient data structures like sets and dictionaries instead of lists when implementing lookup operations or handling unique values.
Example code before:
excluded_items = ['item1', 'item2', 'item3']
if item in excluded_items:
return True
Example code after:
excluded_items = {'item1', 'item2', 'item3'}
if item in excluded_items:
return True
Relevant past accepted suggestions:
Suggestion 1:
Use a set for faster lookup of excluded files
Consider using a set instead of a list for files_to_exclude to improve lookup performance, especially if the list of excluded files grows larger.
pr_agent/tools/pr_help_message.py [90]
-files_to_exclude = ['EXAMPLE_BEST_PRACTICE.md', 'compression_strategy.md', '/docs/overview/index.md']
+files_to_exclude = {'EXAMPLE_BEST_PRACTICE.md', 'compression_strategy.md', '/docs/overview/index.md'}Suggestion 2:
Use any() with a generator expression for more efficient label checking
Consider using any() with a generator expression instead of intersection() for checking excluded labels, as it can be more efficient for small lists.
pr_agent/servers/gitlab_webhook.py [142]
-if labels.intersection(excluded_labels):
+if any(label in excluded_labels for label in labels):
Suggestion 3:
Refactor the mock method to use a dictionary for improved efficiency and maintainability
Consider using a more efficient data structure, such as a dictionary, for the mock_get_content_of_file method. This would improve the readability and maintainability of the code, especially as the number of test cases grows.
tests/unittest/test_bitbucket_provider.py [25-40]

Pattern 4: Add comprehensive security and privacy-related documentation when implementing features that handle sensitive data or authentication.
Example code before:
# Configuration
API_KEY = "<your-key>"
TOKEN = "<your-token>"
Example code after:
# Configuration
# Security Warning: Never commit this file to version control
# Add .env to your .gitignore file
API_KEY = "<your-key>" # Store in environment variables
TOKEN = "<your-token>" # Store in secure credential manager
Relevant past accepted suggestions:
Suggestion 1:
Add security warning about protecting sensitive credentials in environment files
Add a security warning about not committing the .env file to version control, and recommend adding it to .gitignore to prevent accidental exposure of sensitive credentials.
docs/docs/installation/locally.md [77-84]
You can define the environment variables in a plain text file named `.env` with the following content:
CONFIG__GIT_PROVIDER="gitlab" GITLAB__URL="" GITLAB__PERSONAL_ACCESS_TOKEN="" OPENAI__KEY=""
+> ⚠️ **Security Warning**: Never commit the `.env` file to version control as it contains sensitive credentials. Add `.env` to your `.gitignore` file to prevent accidental exposure.
+
Suggestion 2:
Expand on the security and privacy aspects of the PR-Chat feature
Consider adding more details about the security and privacy aspects of the PR-Chat feature. This will help address potential concerns users might have about using the tool.
docs/docs/chrome-extension/index.md [19-20]
-The Chrome extension will not send any code to the server.
-To access code from private repositories, we will first validate the user's identity and permissions, then generate responses using the existing PR-Agent Pro integration.
+### Security and Privacy
+We take your code's security and privacy seriously:
+
+- The Chrome extension does not send any code to external servers.
+- For private repositories, we use secure authentication to validate the user's identity and permissions.
+- Responses are generated using the existing PR-Agent Pro integration, ensuring your code stays within your trusted environment.
+- All communication is encrypted and follows best practices for data protection.
+
+For more details on our security measures, please refer to our [Security Policy](link-to-security-policy).
+Pattern 5: Use version ranges instead of exact versions for dependencies to allow for minor updates and bug fixes while maintaining compatibility.
Example code before:
requests==2.28.1
beautifulsoup4==4.12.3
Example code after:
requests>=2.28.1,<3.0.0
beautifulsoup4>=4.12.3,<5.0.0
Relevant past accepted suggestions:
Suggestion 1:
Use version ranges for new dependencies to allow minor updates
Consider specifying version ranges for the newly added dependencies (beautifulsoup4 and html2text) instead of exact versions. This allows for minor updates and bug fixes without breaking the project.
-beautifulsoup4==4.12.3
-html2text==2024.2.26
+beautifulsoup4>=4.12.3,<5.0.0
+html2text>=2024.2.26,<2025.0.0
