This commit introduces several significant enhancements to the way commands are executed and logged in the application. The changes are primarily focused on improving the robustness, reliability, and transparency of the command execution process, as well as enhancing the quality and usefulness of the log output.
1. Command Execution Enhancements: The use_sudo method has been refactored to handle commands that do not return any output. Previously, the method was designed to capture and return the output of the command being executed. However, some commands (such as modprobe) do not return any output, which caused issues with the previous implementation. The method now checks the exit status of the command to determine whether it was successful or not, and returns a success or failure message accordingly. This change improves the robustness of the command execution process and ensures that it can handle a wider range of commands.
2. Error Handling Improvements: The use_sudo method now includes more comprehensive error handling. If a command fails to execute within a specified timeout period, an error message is logged and the method returns a failure message. Additionally, if a command fails to execute for any other reason, the method logs the error and returns a failure message with the command's exit status. These changes make it easier to identify and troubleshoot issues with command execution.
3. Logging Enhancements: The logging mechanism has been enhanced to provide more detailed and useful information. The use_sudo method now logs the command being executed and its outcome (success or failure). If a command fails, the method logs the command's exit status. These changes improve the transparency of the command execution process and make it easier to identify and troubleshoot issues.
4. Code Refactoring: Several methods have been refactored for improved readability and maintainability. The use_sudo method has been refactored to reduce its complexity and improve its readability. The first_run_setup method has been refactored to ensure that the main interface name and the dummy interface name are properly passed to the setup_traffic_mirroring method.
5. Bug Fixes: A bug in the create_dummy_interface method that caused it to return an array of Alert objects instead of the dummy interface name has been fixed. The method now correctly returns the dummy interface name.
These changes represent a significant improvement to the command execution and logging mechanisms in the application, and lay the groundwork for further enhancements in the future.
In the AlertQueueManager class of the NETRAVE project, we made a
significant change to improve code simplicity, efficiency, and maintainability.
We replaced the previously used Ring Buffer with a standard Array queue for
managing the queue of alerts. This change simplifies the code structure and
improves the efficiency of queue management. As a result of this change, the
Ring Buffer file, which is no longer needed, was also removed from the project.
I would also like to thank Havenwood, Lapizistik, Sampersand, and Crimson
from the Ruby discord in helping me determine the best data structure to use
and helping me generally expand my deeper knowledge of Ruby
This commit marks a significant milestone in the NETRAVE project. The first major system has been successfully completed, laying a solid foundation for the subsequent development phases.
Key changes include:
1. Completion of the Initial Setup Process: The initial setup process has been successfully implemented. This process gathers necessary information from the user and sets up the basic environment for the application to run.
2. Removal of Redundant Thread in Alert System: An unnecessary thread in the alert system was identified and removed. This change simplifies the alert system's architecture and reduces the potential for concurrency-related issues.
3. Program Efficiency Improvements: Several optimizations have been made to enhance the efficiency of the program. These include changes to the way alerts are handled and displayed, as well as improvements to the handling of the alert queue.
These changes have been verified and tested to ensure they work as expected and contribute to the overall functionality and performance of the NETRAVE project.
This commit introduces a significant enhancement to our Ruby program by implementing a thread-safe alert system using a ring buffer data structure.
New Classes:
1. Alert: This class is responsible for creating and displaying alerts in the Curses Text User Interface (TUI). It takes a message and severity level as arguments and uses these to display color-coded alerts to the user.
2. AlertQueueManager: This class manages the queues for alerts using a ring buffer data structure. It continuously checks the queue and displays alerts as they arrive. It uses a mutex lock to ensure thread safety when accessing the ring buffer.
3. RingBuffer: This class is a custom implementation of a ring buffer, also known as a circular buffer. It's a fixed-size buffer that effectively overwrites old data when it is full. The buffer size has been optimized to 2MB to balance memory usage and performance.
Modifications to Existing Methods:
The DatabaseManager class has been updated to integrate the new alert system. The methods in this class now create Alert instances and enqueue them in the AlertQueueManager instead of directly displaying alerts to the user. This change ensures that alerts are displayed in a thread-safe manner and allows for better control over the timing and order of alert displays.
Thread Safety Measures:
Mutex locks and condition variables have been used to synchronize access to the ring buffer and prevent race conditions. This ensures that only one thread can access the buffer at a time, preventing data corruption and ensuring the correct operation of the alert system.
Testing:
Rigorous testing has been conducted to validate the correct functioning of the new system and to handle edge cases. This includes tests for the correct display of alerts, the correct operation of the ring buffer, and the correct synchronization of threads.
Documentation:
Detailed comments have been added to the code to explain the purpose and operation of the new classes and methods. This documentation will serve as a valuable reference for future development and maintenance of the codebase.
This commit represents a significant improvement in the functionality and robustness of our Ruby program's alert system.
