This will allow darkfid restarts, where explorer can still
survive and stay on.
Because of this, added a a code path when processing incoming
blocks that should make the explorer sync blocks if it missed
any in the meantime.
- replace log crate with tracing,
- replace simple-log crate with tracing-subscriber and tracing-appender
- add nu-ansi-term crate as a dependency which is itself tracing-subscriber's dependency,
inorder to write colored outputs to the terminal since we override formatting provided
by tracing-subscriber
This commit updates the explorer web app to run on a Gunicorn-based WSGI server for testnet and mainnet rather than the built-in dev server. In doing so, it provides for improved scalability, reliability, integration with Nginx, and flexible run configuration.
We’ve introduced a dedicated configuration file (gunicorn_config.py) allowing control over the number of worker processes and threads. By adjusting these values, we can handle more simultaneous requests, fine-tune performance based on CPU resources, and tweak other operational parameters to suit deployment needs.
Update Summary:
- Added gunicorn_config.py to configure bind address, workers, threads, pidfile, and logs
- Updated the testnet and mainnet ports to run on 8000 instead of the 5000 dev port
- Created wsgi.py to load and expose the Flask app via `create_app()`
- Updated requirements.txt to include Gunicorn dependency
- Modified makefile start-% target to start with Gunicorn for testnet/mainnet instead of the development server
- Adjusted stop task to stop Gunicorn server when stopping the explorer
- We updated the requirements.txt install to run quietly
- Updated Makefile to export LOG_HOME so it can be accessed by gunicorn_config.py
This update introduces code to ensure blocks with PoW rewards containing coins already applied to the contract state prior to a reorg are synced. Additionally, it brings awareness to the need for rolling back the contract state to a specific height during reorgs.
