4 months ago | ⏱️ Estimated effort to review [1-5] | 4, due to the comprehensive changes across multiple files, including significant logic adjustments in strategy handling, logging, and server configuration. The introduction of new features and the switch to a different logging mechanism increase the complexity of the review. Additionally, the modifications in error handling and strategy shutdown procedures require careful consideration to ensure reliability and robustness. |
| 🧪 Relevant tests | No |
| 🔍 Possible issues | Possible Bug: In `server/src/modules/strategy/strategy.service.ts`, the retry mechanism in error handling could potentially lead to infinite retries if the error persists. This could cause the system to hang or consume excessive resources. |
| Performance Concern: The use of synchronous `await` inside loops, for example in `cancelAllStrategyOrders` and `manageMarketMakingOrdersWithLayers`, could lead to performance bottlenecks. Asynchronous batch processing or parallel execution strategies might be more efficient. | |
| 🔒 Security concerns | No |
| relevant file | server/src/modules/logger/logger.service.ts |
| suggestion | Consider adding a file rotation mechanism or log cleanup strategy to prevent the log files from growing indefinitely, especially for long-running applications. This can be achieved by integrating `winston-daily-rotate-file` transport or implementing a custom cleanup mechanism. [important] |
| relevant line | new winston.transports.File({ |
| relevant file | server/src/modules/marketdata/marketdata.gateway.ts |
| suggestion | For production readiness, ensure that the CORS configuration is updated to restrict origins to known and trusted sources instead of allowing all origins. This is crucial for preventing unwanted cross-origin requests. [important] |
| relevant line | origin: '*', // Allow all origins, Temporary to be changed and restricted. |
| relevant file | server/src/modules/strategy/strategy.service.ts |
| suggestion | Implement a maximum retry limit for error handling in methods like `watchSymbols` and `manageMarketMakingOrdersWithLayers` to prevent infinite loops in case of persistent errors. This could be done by adding a retry counter and a condition to break out of the loop after reaching the limit. [important] |
| relevant line | await new Promise((resolve) => setTimeout(resolve, 2000)); // Wait for 2 seconds before retrying or moving on |
| relevant file | server/src/app.module.ts |
| suggestion | Validate the `POSTGRES_SSL` environment variable to ensure it contains a valid boolean string ('true' or 'false'). Incorrect values could lead to unexpected behavior. Consider adding a utility function for boolean environment variables parsing. [medium] |
| relevant line | ssl: process.env.POSTGRES_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 ``` |
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.

Improve security and reliability by using a configuration service for environment variables.___ **Consider using a more secure method for configuring SSL in production environments. Usingenvironment variables directly can be prone to errors and might not be secure. A better approach would be to use a configuration service or module that validates and sanitizes all environment variables before they are used in the application.** [server/src/app.module.ts [48]](https://github.com/Hu-Fi/Mr.Market/pull/57/files#diff-4e8033eb0f9fd87924c445b7ac0f1c1192d4890fc1589b2fad2679797d4f4ce0R48-R48) ```diff -ssl: process.env.POSTGRES_SSL === 'true', +ssl: configService.get('POSTGRES_SSL') === 'true', ``` |
Implement log file rotation to manage disk space and log file sizes.___ **Implement a mechanism to handle log file rotation to prevent log files from growingindefinitely. This can be achieved by using the winston-daily-rotate-file transport instead of the basic File transport. This will help in managing disk space more effectively and ensure that the log files are easier to manage and review.** [server/src/modules/logger/logger.service.ts [28-34]](https://github.com/Hu-Fi/Mr.Market/pull/57/files#diff-fe4be3a82b6895fc7a5ea6b903fc41dd6b40ea08412f72a46ca9a3dd3962046fR28-R34) ```diff -new winston.transports.File({ - filename: path.join(logsDir, 'error.log'), +new winston.transports.DailyRotateFile({ + filename: path.join(logsDir, '%DATE%-error.log'), + datePattern: 'YYYY-MM-DD', level: 'error', }), -new winston.transports.File({ - filename: path.join(logsDir, 'combined.log'), +new winston.transports.DailyRotateFile({ + filename: path.join(logsDir, '%DATE%-combined.log'), + datePattern: 'YYYY-MM-DD', }), ``` | |
Implement an exponential backoff strategy for retries to improve performance and reliability.___ **Using a fixed delay for retry mechanisms (setTimeout(resolve, 2000)) can lead to suboptimal performance under varying network conditions or load. Implementing an exponential backoff strategy for retries can be more effective, as it adapts to the situation by gradually increasing the delay between retries, reducing the load on the server and increasing the chance of recovery in case of temporary issues.** [server/src/modules/strategy/strategy.service.ts [177]](https://github.com/Hu-Fi/Mr.Market/pull/57/files#diff-413cb1b28e0d47a46768f97d10145a8e14d9e46b0a195768786127305916d944R177-R177) ```diff -await new Promise((resolve) => setTimeout(resolve, 2000)); // Wait for 2 seconds before retrying or moving on +await this.exponentialBackoffRetry(exchange, symbol); ``` | |
Add logic to handle scenarios where the price source is outside the specified ceiling and floor prices.___ **The current implementation does not handle the scenario where the price source is outsidethe specified ceiling and floor prices. It's crucial to add logic to handle this scenario to prevent placing orders that do not align with the strategy's constraints. This could involve logging a warning or error and skipping the order placement for that cycle.** [server/src/modules/strategy/strategy.service.ts [257]](https://github.com/Hu-Fi/Mr.Market/pull/57/files#diff-413cb1b28e0d47a46768f97d10145a8e14d9e46b0a195768786127305916d944R257-R257) ```diff -// Fetch the current market price based on the specified price source type +if (priceSource > ceilingPrice || priceSource < floorPrice) { + this.logger.warn(`Price source ${priceSource} is outside the specified range (Floor: ${floorPrice}, Ceiling: ${ceilingPrice}). Skipping order placement.`); + return; +} ``` | |
| Security |
Enhance security by restricting CORS to specific origins.___ **Restricting CORS to allow all origins ('*') can expose the service to unnecessary security risks. It's recommended to specify a list of allowed origins or to configure CORS dynamically based on the request. This can prevent unwanted cross-origin requests and enhance the security of the WebSocket service.** [server/src/modules/marketdata/marketdata.gateway.ts [24-25]](https://github.com/Hu-Fi/Mr.Market/pull/57/files#diff-b4e30f06d92840d9d06da90af5ce24ca44d2081a7d3cdcd17cd785ab5269e3edR24-R25) ```diff cors: { - origin: '*', // Allow all origins, Temporary to be changed and restricted. + origin: ['https://example.com', 'https://anotherdomain.com'], // Specify allowed origins }, ``` |
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. |
