PR Type

Bug fix, Enhancement, Tests

Description

• Refactored job dependency handling by centralizing the common SQL query into _get_common_dependent_jobs_query.
• Enhanced the enqueue_waiting method to use the centralized query.
• Introduced cancel_dependent_jobs to handle the cancellation of dependent jobs when a parent job is cancelled.
• Added explicit flushes after job state changes to ensure child jobs are updated correctly.
• Added tests to verify the correct state transitions of dependent jobs when a parent job is marked as done or cancelled.

🔒 Security concerns SQL Injection Risk: The use of raw SQL queries in queue_job/job.py without proper input sanitization could lead to SQL injection vulnerabilities. It is recommended to review and refactor these parts of the code to use safer methods of constructing SQL queries.

⚡ Key issues to review SQL Injection Risk The methods _get_common_dependent_jobs_query, enqueue_waiting, and cancel_dependent_jobs use parameterized SQL queries but do not properly sanitize inputs before execution, which could lead to SQL injection vulnerabilities. Consider using parameterized queries or ORM methods to ensure safety. Logical Error The method _change_job_state flushes the queue job environment after setting a job to 'DONE' or 'CANCELLED', which might not be necessary or could lead to performance issues if not properly handled. Review whether this flush is required and ensure it does not impact performance negatively.

PR Code Suggestions ✨

Latest suggestions up to 189a307

Category	Suggestion	Score
Possible issue	Add error handling for database operations to ensure robustness Add error handling for database operations to manage exceptions and rollback transactions if necessary. queue_job/job.py [582-583] -self.env.cr.execute(sql, (CANCELLED, self.uuid, CANCELLED, WAIT_DEPENDENCIES)) -self.env["queue.job"].invalidate_cache(["state"]) +try: + self.env.cr.execute(sql, (CANCELLED, self.uuid, CANCELLED, WAIT_DEPENDENCIES)) + self.env["queue.job"].invalidate_cache(["state"]) +except Exception as e: + self.env.cr.rollback() + raise e Suggestion importance[1-10]: 8 Why: Adding error handling for database operations is a good practice to ensure robustness and manage exceptions properly. The suggestion is well-implemented and addresses a potential issue effectively.	8
Maintainability	Ensure data integrity with explicit transaction management Use explicit transaction management for database operations to ensure data integrity, especially when modifying job states. queue_job/job.py [577-578] +self.env.cr.execute('BEGIN;') self.env.cr.execute(sql, (PENDING, self.uuid, DONE, WAIT_DEPENDENCIES)) self.env["queue.job"].invalidate_cache(["state"]) +self.env.cr.execute('COMMIT;') Suggestion importance[1-10]: 7 Why: Adding explicit transaction management can help ensure data integrity, especially when modifying job states. However, the suggestion could be improved by including error handling to manage transaction rollbacks in case of failure.	7
	Refactor complex conditional logic into a separate method for clarity Refactor the state management logic to a separate method to reduce complexity and improve maintainability. queue_job/models/queue_job.py [308-312] -if state == DONE: +def handle_state_done(job_, result): job_.set_done(result=result) job_.store() record.env["queue.job"].flush() job_.enqueue_waiting() +handle_state_done(job_, result) Suggestion importance[1-10]: 6 Why: Refactoring the state management logic into a separate method can improve code readability and maintainability. However, the suggestion does not account for the context in which record is defined, which may lead to errors.	6

Category	Suggestion	Score
Maintainability	Add logging for state changes and operations to aid in debugging Add logging to track the changes in job states and flush operations, which will help in debugging and maintaining the state transitions. queue_job/models/queue_job.py [311-320] record.env["queue.job"].flush() +logger.info("Flushed queue job states after setting to %s", state) job_.cancel_dependent_jobs() +logger.info("Cancelled dependent jobs after job state set to %s", state) Suggestion importance[1-10]: 9 Why: Adding logging for state changes and operations is a good practice for debugging and maintaining state transitions. The suggestion correctly adds informative logging statements.	9
	Implement error handling for database operations to improve reliability Add error handling for database operations in enqueue_waiting and cancel_dependent_jobs to manage exceptions and ensure database integrity. queue_job/job.py [577-582] -self.env.cr.execute(sql, (PENDING, self.uuid, DONE, WAIT_DEPENDENCIES)) -self.env.cr.execute(sql, (CANCELLED, self.uuid, CANCELLED, WAIT_DEPENDENCIES)) +try: + self.env.cr.execute(sql, (PENDING, self.uuid, DONE, WAIT_DEPENDENCIES)) +except Exception as e: + logger.error("Failed to enqueue waiting jobs: %s", e) + raise +try: + self.env.cr.execute(sql, (CANCELLED, self.uuid, CANCELLED, WAIT_DEPENDENCIES)) +except Exception as e: + logger.error("Failed to cancel dependent jobs: %s", e) + raise Suggestion importance[1-10]: 8 Why: Adding error handling for database operations is a good practice to ensure reliability and maintainability. The suggestion correctly adds try-except blocks to manage exceptions.	8
	Consolidate repeated method calls into a single call post conditions Refactor the repeated job_.store() calls into a single call after the state-setting conditions to reduce redundancy and improve code maintainability. queue_job/models/queue_job.py [308-318] -job_.set_done(result=result) -job_.store() -job_.set_pending(result=result) -job_.store() -job_.set_cancelled(result=result) +job_.set_done(result=result) if state == DONE else job_.set_pending(result=result) if state == PENDING else job_.set_cancelled(result=result) job_.store() Suggestion importance[1-10]: 7 Why: The suggestion to refactor repeated job_.store() calls into a single call is valid and improves code maintainability by reducing redundancy. However, the ternary conditional expression used in the improved code may reduce readability.	7
