Go to file
Pawan Dhananjay e3d45eda1e Log to file without json format (#1485) 
## Issue Addressed

N/A

## Proposed Changes

Earlier, to log to a file, the only options were to redirect stdout/stderr to a file or use json logging. 
Redirecting to stdout/stderr works well but causes issues with mistakenly overwriting the file instead of appending which has resulted in loss of precious logs on multiple occasions for me.

Json logging creates a timestamped backup of the file if it already exists, but the json format itself is hugely annoying.

This PR modifies the `--logfile` option to log as it does in the terminal to a logfile.

Overview

Lighthouse is:

  • Fully open-source, licensed under Apache 2.0.
  • Security-focused. Fuzzing has begun and security reviews are underway.
  • Built in Rust, a modern language providing unique safety guarantees and excellent performance (comparable to C++).
  • Funded by various organisations, including Sigma Prime, the Ethereum Foundation, ConsenSys and private individuals.
  • Actively involved in the specification and security analysis of the emerging Ethereum 2.0 specification.

Like all Ethereum 2.0 clients, Lighthouse is a work-in-progress.

Development Status

Current development overview:

  • Specification v0.12.1 implemented, optimized and passing test vectors.
  • Rust-native libp2p with Gossipsub and Discv5.
  • RESTful JSON API via HTTP server.
  • Events via WebSocket.
  • Metrics via Prometheus.

Roadmap

  • April 2019: Inital single-client testnets.
  • September 2019: Inter-operability with other Ethereum 2.0 clients.
  • Q1 2020: lighthouse-0.1.0 release: All major phase 0 features implemented.
  • Q2 2020: Public, multi-client testnet with user-facing functionality.
  • Q2 2020: Third-party security review.
  • Q3 2020: Additional third-party security reviews.
  • Q3 2020: Long-lived, multi-client Beacon Chain testnet
  • Q4 2020: Production Beacon Chain (tentative).

Documentation

The Lighthouse Book contains information for testnet users and developers.

Code documentation is generated via cargo doc and hosted at lighthouse-docs.sigmaprime.io.
