    PR Review

    โฑ๏ธ Estimated effort to review [1-5] 3, because the PR involves changes across multiple files including shell scripts, Dockerfile, and Supervisor configuration files. Understanding the context and impact of these changes requires a good grasp of the system architecture and the specific roles these configurations play.
    ๐Ÿงช Relevant tests No
    ๐Ÿ” Possible issues Possible Bug: The removal of subshells in `start.sh` might lead to unexpected behavior if any of the commands rely on being executed in a subshell environment.
    Configuration Concern: Changing `autostart` to `false` in `horizon.conf` might delay necessary services from starting automatically, requiring manual intervention.
    ๐Ÿ”’ Security concerns No
    Code feedback:
    relevant fileconfigs/core/start.sh
    suggestion       Consider adding error handling for each command in the script to ensure that the script stops executing if any command fails. This can be achieved by adding `set -e` at the beginning of the script. [important]
    relevant linephp artisan cache:clear && php artisan config:cache && php artisan migrate && php artisan platform:sync && php artisan platform:ingest

    relevant fileconfigs/core/Dockerfile
    suggestion       It's recommended to avoid using `chmod 777` for directory permissions due to security concerns. Consider using more restrictive permissions that allow necessary access to the `www-data` user and group only. [important]
    relevant lineRUN chmod 777 -R /var/www/html/storage/

    relevant fileconfigs/core/supervisor/conf.d/horizon.conf
    suggestion       If `autostart` is set to `false`, ensure there's a mechanism in place (either manual or automated) to start this service when needed. This change might affect deployments expecting `horizon` to start automatically. [medium]
    relevant lineautostart=false

    relevant fileconfigs/core/supervisor/supervisord.conf
    suggestion       Ensure that the `chown=www-data:www-data` directive in the `[supervisord]` section is necessary and correctly applied, as it might lead to permission issues if other processes need access to the supervisor logs or pid files. [medium]

    โœจ Review tool usage guide:
    **Overview:** The `review` tool scans the PR code changes, and generates a PR review. The tool can be triggered [automatically](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#github-app-automatic-tools) every time a new PR is opened, or can be invoked manually by commenting on any PR. When commenting, to edit [configurations](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml#L19) related to the review tool (`pr_reviewer` section), use the following template: ``` /review --pr_reviewer.some_config1=... --pr_reviewer.some_config2=... ``` With a [configuration file](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#working-with-github-app), use the following template: ``` [pr_reviewer] some_config1=... some_config2=... ```
    Utilizing extra instructions
    The `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-labels
    The `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-tools
    The `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 PRs
    By 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.

    Best practice
    Wrap command sequences in a subshell with error checking. ___ **Consider wrapping the command sequence in a subshell using parentheses and adding set -e
    at the beginning. This ensures that if any command in the sequence fails, the script stops
    execution and exits with an error, making it easier to detect and troubleshoot issues.** [configs/core/start.sh [8]](https://github.com/enjin/platform/pull/34/files#diff-1ab5cfcfc8e032f585b6a70cb59659ea3d92417af421a27973951c09f32d90c4R8-R8) ```diff -php artisan cache:clear && php artisan config:cache && php artisan migrate && php artisan platform:sync && php artisan platform:ingest +(set -e; php artisan cache:clear && php artisan config:cache && php artisan migrate && php artisan platform:sync && php artisan platform:ingest) ```
    Check if supervisord starts successfully before running supervisorctl. ___ **It's recommended to check if supervisord successfully starts before attempting to start
    horizon with supervisorctl. You can achieve this by checking the exit status of
    supervisord.** [configs/core/start.sh [22]](https://github.com/enjin/platform/pull/34/files#diff-1ab5cfcfc8e032f585b6a70cb59659ea3d92417af421a27973951c09f32d90c4R22-R22) ```diff -supervisord && supervisorctl start horizon +supervisord +if [ $? -eq 0 ]; then + supervisorctl start horizon +else + echo "Failed to start supervisord." + exit 1 +fi ```
    Security
    Use more secure file permissions for storage. ___ **Using chmod 777 for storage permissions is insecure and can expose the application to
    unnecessary risks. Consider using more restrictive permissions and ensuring that the
    www-data user has the necessary access.** [configs/core/Dockerfile [61]](https://github.com/enjin/platform/pull/34/files#diff-53fa4c640b742cdc1f8a7d279e3de8a327c6a292df15236362f5bb985a872970R61-R61) ```diff -RUN chmod 777 -R /var/www/html/storage/ +RUN chown -R www-data:www-data /var/www/html/storage/ && chmod -R 755 /var/www/html/storage/ ```
    Review socket file permissions for appropriate access control. ___ **The chmod=0700 for the Unix socket file restricts access to the supervisord socket to only
    the user that supervisord is running as. Ensure that any processes or users that need to
    communicate with supervisord through this socket have the appropriate access permissions.** [configs/core/supervisor/supervisord.conf [5]](https://github.com/enjin/platform/pull/34/files#diff-f60feee5c233ad7bea6bad948278a8339361f0c711d86b32b5c87007a983ef99R5-R5) ```diff -chmod=0700 ; sockef file mode (default 0700) +chmod=0770 ; Adjust the mode as necessary for your security requirements and user groups ```
    Possible issue
    Review the autostart setting for horizon. ___ **The autostart=false setting prevents horizon from starting automatically when supervisord
    starts. If this is intentional, ensure that there's a mechanism in place to start it when
    needed. Otherwise, consider setting autostart=true for automatic startup.** [configs/core/supervisor/conf.d/horizon.conf [4]](https://github.com/enjin/platform/pull/34/files#diff-de7c9afabc2cdeb40605ff63e340372e25ee275a7a1973430dce5e391665914dR4-R4) ```diff -autostart=false +autostart=true ```

    โœจ Improve tool usage guide:
    **Overview:** The `improve` tool scans the PR code changes, and automatically generates suggestions for improving the PR code. The tool can be triggered [automatically](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#github-app-automatic-tools) every time a new PR is opened, or can be invoked manually by commenting on a PR. When commenting, to edit [configurations](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml#L69) related to the improve tool (`pr_code_suggestions` section), use the following template: ``` /improve --pr_code_suggestions.some_config1=... --pr_code_suggestions.some_config2=... ``` With a [configuration file](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#working-with-github-app), use the following template: ``` [pr_code_suggestions] some_config1=... some_config2=... ```
    Enabling\disabling automation
    When 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 instructions
    Extra 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.
