Firedancer

Appearance

Software Supply Chain ​

Below is a list of third-party software that is either included in Firedancer source code (vendored) or required to build Firedancer.

Development-only dependencies are omitted.

The purpose of this document is to list relevant exposure to third-party code changes. Low-risk vendored code that was exhaustively tested for correctness, is near-immutable, or fully maintained by the Firedancer team is not included in this list. (This includes, e.g., the Ed25519 and ChaCha modules.)

FRANKENDANCER

This document only covers full Firedancer. Frankendancer is omitted because of Agave's extremely large and rapidly changing set of dependencies. It would therefore be impractical to adequately document Agave's or Frankendancer's software supply chain.

For copyright notices of vendored code, see the NOTICE file instead.

Distribution ​

Firedancer source code is distributed via GitHub.com.

System environment ​

Firedancer requires a glibc-based Linux environment, either Fedora- or Ubuntu-like.

Build dependencies ​

Build dependencies are installed via the system's native package manager (dnf or apt) when running ./deps.sh check. These include:

  • GNU Make
  • C compiler: GCC or Clang
  • GNU coreutils
  • Perl (for building Agave's OpenSSL)

Vendored ​

This section only lists vendored code that requires interaction with third-party repositories (e.g. pulling bug fixes). Other vendored code is omitted (see the NOTICE file above for a complete list).

Vendored libraries live under src/third_party/ (see the README there for the vendoring conventions).
