[enjinabner]

PR Type

Bug fix

---

Description

• Wrapped the DispatchMutation resolve method with explicit database transaction handling using DB::beginTransaction() and DB::commit().
• Simplified the return statement by removing the nested transaction call and storing the transaction result in a variable.

PR Code Suggestions ✨

Category	Suggestion	Score
Possible issue	Add error handling for the database transaction Add a DB::rollBack() in a catch block to handle exceptions that might occur during the transaction. This ensures that the database state is reverted if an error occurs after the transaction has started but before it is committed. src/GraphQL/Mutations/DispatchMutation.php [101-104] DB::beginTransaction(); -$encodedCall = static::getFuelTankCall($this->getMethodName(), $args); -$transaction = $this->storeTransaction($args, $encodedCall); -DB::commit(); +try { + $encodedCall = static::getFuelTankCall($this->getMethodName(), $args); + $transaction = $this->storeTransaction($args, $encodedCall); + DB::commit(); +} catch (\Exception $e) { + DB::rollBack(); + throw $e; +} Suggestion importance[1-10]: 10 Why: This suggestion is crucial for ensuring database integrity by rolling back the transaction in case of an exception, preventing partial commits and potential data corruption.	10
Best practice	Ensure safe commit of transactions Ensure that DB::commit() is only called if there are no exceptions by placing it inside a try block. This prevents committing a transaction that might have encountered issues during execution. src/GraphQL/Mutations/DispatchMutation.php [102-104] -$encodedCall = static::getFuelTankCall($this->getMethodName(), $args); -$transaction = $this->storeTransaction($args, $encodedCall); -DB::commit(); +try { + $encodedCall = static::getFuelTankCall($this->getMethodName(), $args); + $transaction = $this->storeTransaction($args, $encodedCall); + DB::commit(); +} catch (\Exception $e) { + DB::rollBack(); + throw $e; +} Suggestion importance[1-10]: 9 Why: This suggestion is important for maintaining data integrity by ensuring that the commit only occurs if no exceptions are thrown, which aligns with best practices for transaction management.	9
Enhancement	Verify transaction storage success before committing Consider checking the success of storeTransaction before committing the transaction. This can prevent committing incomplete or incorrect data. src/GraphQL/Mutations/DispatchMutation.php [103-104] $transaction = $this->storeTransaction($args, $encodedCall); -DB::commit(); +if ($transaction) { + DB::commit(); +} else { + DB::rollBack(); + throw new \Exception("Failed to store transaction"); +} Suggestion importance[1-10]: 8 Why: This enhancement adds an additional layer of validation to ensure that the transaction is only committed if the storeTransaction method succeeds, which helps in maintaining data accuracy.	8
Maintainability	Implement logging for transaction processes Add logging for the transaction process to aid in debugging and monitoring the transaction states. src/GraphQL/Mutations/DispatchMutation.php [101-104] DB::beginTransaction(); -$encodedCall = static::getFuelTankCall($this->getMethodName(), $args); -$transaction = $this->storeTransaction($args, $encodedCall); -DB::commit(); +Log::info("Transaction started"); +try { + $encodedCall = static::getFuelTankCall($this->getMethodName(), $args); + $transaction = $this->storeTransaction($args, $encodedCall); + DB::commit(); + Log::info("Transaction committed"); +} catch (\Exception $e) { + DB::rollBack(); + Log::error("Transaction failed: " . $e->getMessage()); + throw $e; +} Suggestion importance[1-10]: 7 Why: Adding logging improves maintainability by providing insights into the transaction process, which can be valuable for debugging and monitoring purposes.	7

Should we use simulate = true in the first call? That way it doesn't save

Simulate will bypass the validations, i think we need all of that.

Are you sure? I thought only skipValidation bypassed the validations

Right, i totally forgot about that. But still, i think wrapping with transaction is still the safest. If there's something being committed in the DB while getting the encoded call and the mutation crashed, it can be rolled back.

Cases like this, is what i meant, but this one should be okay.
