6 months ago | ⏱️ Estimated effort to review [1-5] | 4, due to the extensive changes across multiple files, including the addition of new modules, services, and tests. The complexity of integrating a custom logger and modifying existing services to use it, alongside the introduction of environment variable configurations for ports, requires careful consideration of the overall architecture and potential side effects. |
| 🧪 Relevant tests | Yes |
| 🔍 Possible issues | Possible Bug: In `server/src/modules/marketdata/marketdata.gateway.ts`, the conversion of `webSocketPort` from string to number using `parseInt` without specifying a radix might lead to unexpected results. It's recommended to always specify a radix of 10 for decimal numbers. |
| Performance Concern: The use of synchronous file operations in `server/src/modules/logger/logger.service.ts` could potentially block the event loop, especially under high load. Consider using asynchronous file operations instead. | |
| Error Handling: Several services and controllers lack comprehensive error handling, which could lead to unhandled exceptions and affect the stability of the application. | |
| 🔒 Security concerns | No |
| relevant file | server/src/modules/marketdata/marketdata.gateway.ts |
| suggestion | Consider specifying a radix of 10 when using `parseInt` for converting `webSocketPort` to a number. This ensures the string is always interpreted in the decimal numeral system, avoiding potential bugs. [important] |
| relevant line | const webSocketPort = process.env.WS_PORT || "3012"; |
| relevant file | server/src/modules/logger/logger.service.ts |
| suggestion | Replace synchronous file operations with their asynchronous counterparts to prevent blocking the event loop. This change enhances the performance and scalability of the application by ensuring that logging operations do not interfere with the main application flow. [important] |
| relevant line | fs.appendFile(filePath, message, (err) => { |
| relevant file | server/src/modules/trade/trade.service.ts |
| suggestion | Implement comprehensive error handling for external API calls and database operations. This could include try-catch blocks around API calls and checks for successful database operations, logging the errors and potentially retrying operations or gracefully degrading functionality. [important] |
| relevant line | service['exchanges'].get('binance').createOrder = jest.fn().mockResolvedValue(mockOrder); |
| relevant file | server/src/modules/strategy/strategy.service.ts |
| suggestion | Validate the existence and configuration of exchanges before attempting to use them in strategies. This can prevent `InternalServerErrorException` by ensuring that only configured exchanges are used, improving the robustness of the application. [medium] |
| relevant line | const exchangeA: ccxt.Exchange = this.exchanges.get(exchangeAName); |
Utilizing extra instructionsThe `review` tool can be configured with extra instructions, which can be used to guide the model to a feedback tailored to the needs of your project. Be specific, clear, and concise in the instructions. With extra instructions, you are the prompter. Specify the relevant sub-tool, and the relevant aspects of the PR that you want to emphasize. Examples for extra instructions: ``` [pr_reviewer] # /review # extra_instructions=""" In the 'possible issues' section, emphasize the following: - Does the code logic cover relevant edge cases? - Is the code logic clear and easy to understand? - Is the code logic efficient? ... """ ``` Use triple quotes to write multi-line instructions. Use bullet points to make the instructions more readable. |
How to enable\disable automation- When you first install PR-Agent app, the [default mode](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#github-app-automatic-tools) for the `review` tool is: ``` pr_commands = ["/review", ...] ``` meaning the `review` tool will run automatically on every PR, with the default configuration. Edit this field to enable/disable the tool, or to change the used configurations |
Auto-labelsThe `review` tool can auto-generate two specific types of labels for a PR: - a `possible security issue` label, that detects possible [security issues](https://github.com/Codium-ai/pr-agent/blob/tr/user_description/pr_agent/settings/pr_reviewer_prompts.toml#L136) (`enable_review_labels_security` flag) - a `Review effort [1-5]: x` label, where x is the estimated effort to review the PR (`enable_review_labels_effort` flag) |
Extra sub-toolsThe `review` tool provides a collection of possible feedbacks about a PR. It is recommended to review the [possible options](https://github.com/Codium-ai/pr-agent/blob/main/docs/REVIEW.md#enabledisable-features), and choose the ones relevant for your use case. Some of the feature that are disabled by default are quite useful, and should be considered for enabling. For example: `require_score_review`, `require_soc2_ticket`, and more. |
Auto-approve PRsBy invoking: ``` /review auto_approve ``` The tool will automatically approve the PR, and add a comment with the approval. To ensure safety, the auto-approval feature is disabled by default. To enable auto-approval, you need to actively set in a pre-defined configuration file the following: ``` [pr_reviewer] enable_auto_approval = true ``` (this specific flag cannot be set with a command line argument, only in the configuration file, committed to the repository) You can also enable auto-approval only if the PR meets certain requirements, such as that the `estimated_review_effort` is equal or below a certain threshold, by adjusting the flag: ``` [pr_reviewer] maximal_review_effort = 5 ``` |
More PR-Agent commands> To invoke the PR-Agent, add a comment using one of the following commands: > - **/review**: Request a review of your Pull Request. > - **/describe**: Update the PR title and description based on the contents of the PR. > - **/improve [--extended]**: Suggest code improvements. Extended mode provides a higher quality feedback. > - **/ask \ |

Add detailed logging before critical operations.___ **For better error handling and debugging, consider adding more detailed logging, especiallybefore performing critical operations like executing trades.** [server/src/modules/trade/trade.service.ts [69]](https://github.com/Hu-Fi/Mr.Market/pull/39/files#diff-4432350be63f9e2463145381a3748ee74fcf5656391b0269244b96a3bd55bd3eR69-R69) ```diff -this.logger.log(`Market trade executed`, order.toString()); +this.logger.log(`Attempting to execute market trade with order details: ${JSON.stringify(order)}`); +// Followed by the execution ``` | |
Mock external dependencies more comprehensively in tests.___ **To improve the robustness of your tests, consider mocking external dependencies morecomprehensively.

Add tests for partial failures or exceptions during trade execution.___ **To ensure that your tests cover all possible scenarios, consider adding tests for partialfailures or exceptions during the trade execution process, such as network issues or partial order fulfillment.** [server/src/modules/trade/trade.service.spec.ts [107-120]](https://github.com/Hu-Fi/Mr.Market/pull/39/files#diff-81f72944db3b1b77fd408110e28d0460e05facb92b2416e4732d6c1d478bb00eR107-R120) ```diff -it('should throw InternalServerErrorException on createOrder failure', async () => { - const limitTradeDto = { - userId: 'user123', - clientId: 'client123', - exchange: 'binance', - symbol: 'BTC/USD', - side: 'sell', - amount: 1, - price: 50000, - }; - - ccxt.pro.binance.prototype.createOrder = jest.fn().mockRejectedValue(new Error('API Error')); - - await expect(service.executeLimitTrade(limitTradeDto)).rejects.toThrow(InternalServerErrorException); +// Example of an additional test case +it('should handle partial order fulfillment', async () => { + // Setup partial fulfillment scenario + // Assert the expected behavior }); ``` |
Enabling\disabling automationWhen you first install the app, the [default mode](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#github-app-automatic-tools) for the improve tool is: ``` pr_commands = ["/improve --pr_code_suggestions.summarize=true", ...] ``` meaning the `improve` tool will run automatically on every PR, with summarization enabled. Delete this line to disable the tool from running automatically. |
Utilizing extra instructionsExtra instructions are very important for the `improve` tool, since they enable to guide the model to suggestions that are more relevant to the specific needs of the project. Be specific, clear, and concise in the instructions. With extra instructions, you are the prompter. Specify relevant aspects that you want the model to focus on. Examples for extra instructions: ``` [pr_code_suggestions] # /improve # extra_instructions=""" Emphasize the following aspects: - Does the code logic cover relevant edge cases? - Is the code logic clear and easy to understand? - Is the code logic efficient? ... """ ``` Use triple quotes to write multi-line instructions. Use bullet points to make the instructions more readable. |
A note on code suggestions quality- While the current AI for code is getting better and better (GPT-4), it's not flawless. Not all the suggestions will be perfect, and a user should not accept all of them automatically. - Suggestions are not meant to be simplistic. Instead, they aim to give deep feedback and raise questions, ideas and thoughts to the user, who can then use his judgment, experience, and understanding of the code base. - Recommended to use the 'extra_instructions' field to guide the model to suggestions that are more relevant to the specific needs of the project, or use the [custom suggestions :gem:](https://github.com/Codium-ai/pr-agent/blob/main/docs/CUSTOM_SUGGESTIONS.md) tool - With large PRs, best quality will be obtained by using 'improve --extended' mode. |
