Proper Cancellation Handling

Improving Reliability and Performance: A Comprehensive Solution

In our latest update, we have implemented a comprehensive solution to resolve the freezing issues in the email extraction script. This solution addresses the root causes of the problems and ensures that the script runs smoothly and efficiently. The key changes include:

Hierarchical Timeouts: We have added hierarchical timeouts with strict enforcement at all levels, including HTTP requests, Playwright operations, and batch processing. This ensures that each operation has a time limit, preventing any single operation from blocking the entire process indefinitely.
Semaphore Limiting: We have added semaphore limiting to Playwright, limiting it to 3 concurrent instances. This prevents resource exhaustion and ensures that the script runs within the available resources.
Proper Cancellation Handling: We have improved proper cancellation handling and resource cleanup throughout the codebase. This ensures that the script can be cancelled or interrupted without causing any issues or leaving behind any resources.
Browser Configuration Tweaks: We have enhanced browser configuration tweaks for stability and added fallback mechanisms for error recovery. This ensures that the script can recover from errors and continue running smoothly.

The Impact of These Changes

These changes have significantly improved the reliability and performance of the email extraction script. The script now runs smoothly and efficiently, without freezing or hanging indefinitely. The hierarchical timeouts and semaphore limiting ensure that each operation has a time limit and that the script runs within the available resources. The proper cancellation handling and resource cleanup ensure that the script can be cancelled or interrupted without causing any issues or leaving behind any resources.

Still Room for Improvement

Despite these improvements, there are still some cases where the script hangs indefinitely. This is often due to URLs in the batches that cause the script to freeze. We are still working on resolving these issues and improving the script's reliability and performance.

Investigating the Remaining Issues

We are currently investigating the remaining issues that cause the script to hang indefinitely. We are working on identifying the root causes of these issues and implementing solutions to resolve them. This includes:

Analyzing the Script's Behavior: We are analyzing the script's behavior to identify the specific operations that cause the script to freeze.
Testing and Debugging: We are testing and debugging the script to identify the root causes of the issues and implementing solutions to resolve them.
Improving the Script's Design: We are improving the script's design to make it more robust and reliable. This includes adding more checks and balances to prevent the script from freezing or hanging indefinitely.

Conclusion

In conclusion, our latest update has significantly improved the reliability and performance of the email extraction script. The comprehensive solution we have implemented addresses the root causes of the freezing issues and ensures that the script runs smoothly and efficiently. However, there are still some cases where the script hangs indefinitely, and we are working on resolving these issues. We are committed to continuously improving the script's reliability and performance and ensuring that it meets the needs of our users.
