Michael Sproul d9910f96c5 Remove SIGPIPE handler (#2558)
## Proposed Changes

Remove the SIGPIPE handler added in #2486.

We saw some of the testnet nodes running under `systemd` being stopped due to `journald` restarts. The systemd docs state:

> If systemd-journald.service is stopped, the stream connections associated with all services are terminated. Further writes to those streams by the service will result in EPIPE errors. In order to react gracefully in this case it is recommended that programs logging to standard output/error ignore such errors. If the SIGPIPE UNIX signal handler is not blocked or turned off, such write attempts will also result in such process signals being generated, see signal(7).

From https://www.freedesktop.org/software/systemd/man/systemd-journald.service.html

## Additional Info

It turned out that the issue described in #2114 was due to `tee`'s behaviour rather than Lighthouse's, so the SIGPIPE handler isn't required for any current use case. An alternative to disabling it all together would be to exit with a non-zero code so that systemd knows to restart the process, but it seems more desirable to tolerate journald glitches than to restart frequently.

  • Ready for use on Eth2 mainnet.
  • Fully open-source, licensed under Apache 2.0.
  • Security-focused. Fuzzing techniques have been continuously applied and several external security reviews have been performed.
  • 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, the Decentralization Foundation and private individuals.
  • Actively involved in the specification and security analysis of the Ethereum 2.0 specification.

Eth2 Deposit Contract

The Lighthouse team acknowledges 0x00000000219ab540356cBB839Cbe05303d7705Fa as the canonical Eth2 deposit contract address.

Documentation

The Lighthouse Book contains information for users and developers.

The Lighthouse team maintains a blog at lighthouse.sigmaprime.io which contains periodical progress updates, roadmap insights and interesting findings.

Branches

Lighthouse maintains two permanent branches:

  • stable: Always points to the latest stable release.
    • This is ideal for most users.
  • unstable: Used for development, contains the latest PRs.
    • Developers should base their PRs on this branch.
