6 months ago | ⏱️ Estimated effort to review [1-5] | 4, due to the comprehensive nature of the changes across multiple files, including backend logic, configuration, and logging. The modifications touch on critical areas such as security (SSL), logging, CORS, WebSocket connections, and strategy handling which require careful review to ensure they meet the project's standards and do not introduce regressions or security vulnerabilities. |
| 🧪 Relevant tests | No |
| 🔍 Possible issues | Possible Bug: The use of `parseInt(webSocketPort, 10)` in `server/src/modules/marketdata/marketdata.gateway.ts` is correct for ensuring the port is an integer, but the environment variable should be validated to ensure it exists and is a valid number to prevent runtime errors. |
| Performance Concern: In `server/src/modules/strategy/strategy.service.ts`, the retry mechanism with a fixed delay (e.g., `await new Promise((resolve) => setTimeout(resolve, 2000));`) could lead to inefficiencies under high load or if the external service (e.g., exchange) is experiencing prolonged issues. A more sophisticated backoff strategy might be beneficial. | |
| Code Quality: The method `cancelAllStrategyOrders` in `server/src/modules/strategy/strategy.service.ts` iterates over orders and attempts to cancel them one by one, logging failures individually. This could be improved by aggregating failures and handling them more efficiently. | |
| 🔒 Security concerns | No |
| relevant file | server/src/modules/marketdata/marketdata.gateway.ts |
| suggestion | Consider validating the `WS_PORT` environment variable to ensure it's provided and is a valid number. This can prevent runtime errors related to WebSocket server initialization. [important] |
| relevant line | @WebSocketGateway(parseInt(webSocketPort, 10), { |
| relevant file | server/src/modules/strategy/strategy.service.ts |
| suggestion | Implement an exponential backoff strategy for retrying failed operations instead of using a fixed delay. This can improve the efficiency of retries, especially under varying network conditions or service availability. [important] |
| relevant line | await new Promise((resolve) => setTimeout(resolve, 2000)); // Wait for 2 seconds before retrying or moving on |
| relevant file | server/src/modules/strategy/strategy.service.ts |
| suggestion | Aggregate errors when canceling multiple orders in `cancelAllStrategyOrders` and handle them collectively, possibly with a retry mechanism for failed cancellations. This can improve error handling and make the code more resilient. [medium] |
| relevant line | this.logger.error(`Failed to cancel order ${orderId}: ${error}`); |
| relevant file | server/src/app.module.ts |
| suggestion | Ensure that the SSL configuration for PostgreSQL is compatible with your deployment environment and that necessary certificates are properly managed, especially in containerized or cloud environments. [important] |
| relevant line | ssl: true, |
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 ``` |

| Security |
Enhance database connection security by verifying the server's certificate.___ **When enabling SSL for database connections in production, it's crucial to verify theserver's certificate to prevent Man-In-The-Middle (MITM) attacks. Consider using a more secure configuration that includes rejectUnauthorized: true and specifies the CA (Certificate Authority) certificate.** [server/src/app.module.ts [48]](https://github.com/Hu-Fi/Mr.Market/pull/42/files#diff-4e8033eb0f9fd87924c445b7ac0f1c1192d4890fc1589b2fad2679797d4f4ce0R48-R48) ```diff -ssl: true, +ssl: { + rejectUnauthorized: true, + ca: fs.readFileSync('/path/to/server-certificates/ca.crt').toString(), +}, ``` |
Restrict CORS to known origins for improved security.___ **The current CORS configuration allows requests from any origin, which might expose theserver to security risks. It's recommended to specify allowed origins or to configure CORS more restrictively based on the deployment environment.** [server/src/main.ts [9]](https://github.com/Hu-Fi/Mr.Market/pull/42/files#diff-efcd503ed2db1beff4ecb4063d7ff5cfb7de483a66d9f9a4ff296daea9f8e868R9-R9) ```diff -app.enableCors(); +app.enableCors({ + origin: ['https://example.com', 'https://www.example.org'], +}); ``` | |
Restrict WebSocket CORS origins for better security.___ **Allowing all origins for WebSocket connections can be a security risk. It's advisable torestrict the cors.origin to the specific domains that should be allowed to connect, or to configure it based on the environment.** [server/src/modules/marketdata/marketdata.gateway.ts [24]](https://github.com/Hu-Fi/Mr.Market/pull/42/files#diff-b4e30f06d92840d9d06da90af5ce24ca44d2081a7d3cdcd17cd785ab5269e3edR24-R24) ```diff -origin: '*', // Allow all origins, Temporary to be changed and restricted. +origin: ['https://yourdomain.com', 'https://www.anotherdomain.com'], ``` | |
| Enhancement |
Use an environment variable for the logging level to enhance flexibility.___ **To improve the logging mechanism's flexibility and maintainability, consider adding anenvironment variable for the logging level. This allows for easy adjustments in different environments without changing the code.** [server/src/modules/logger/logger.service.ts [16]](https://github.com/Hu-Fi/Mr.Market/pull/42/files#diff-fe4be3a82b6895fc7a5ea6b903fc41dd6b40ea08412f72a46ca9a3dd3962046fR16-R16) ```diff -level: 'info', // Default logging level +level: process.env.LOG_LEVEL || 'info', ``` |
Improve order cancellation error handling with retries or aggregation.___ **The current implementation ofcancelAllStrategyOrders does not handle potential errors for each order cancellation in a way that ensures all orders are attempted to be cancelled. Consider adding a retry mechanism or aggregating errors to handle them after attempting all cancellations.** [server/src/modules/strategy/strategy.service.ts [372-375]](https://github.com/Hu-Fi/Mr.Market/pull/42/files#diff-413cb1b28e0d47a46768f97d10145a8e14d9e46b0a195768786127305916d944R372-R375) ```diff -await exchange.cancelOrder(order.id, pair); +try { + await exchange.cancelOrder(order.id, pair); +} catch (error) { + errors.push({ orderId: order.id, error }); + // Optionally, add a retry mechanism here +} ``` |
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. |
