Overview

Sinatra-based HTTP forward proxy server used as an in-process Nonnative server.

The proxy receives inbound HTTP requests and forwards them to an upstream host over HTTPS, returning the upstream response status and body.

This file defines two classes:

.clear ⇒ void

This method returns an undefined value.

Clears memoized configuration, logger, observability client, and pool.

# File 'lib/nonnative.rb', line 180

def log_lines(path, predicate)
  File.readlines(path).select { |l| predicate.call(l) }
end

.logger ⇒ Logger

# File 'lib/nonnative.rb', line 232

def observability = (@observability ||= Nonnative::Observability.new(configuration.url))

.proxies ⇒ Hash{String=>Class}

Returns the configured proxy kinds mapped to proxy classes.

Consumers can extend this map to add custom proxy implementations.

Returns:

  • (Hash{String=>Class})

# File 'lib/nonnative.rb', line 248

def proxies
  @proxies ||= { 'fault_injection' => Nonnative::FaultInjectionProxy }
end

.proxy(kind) ⇒ Class

Resolves a proxy implementation for a configured kind.

nil and "none" resolve to NoProxy; any other kind must be registered in proxies.

Parameters:

  • kind (String) —

    proxy kind name (for example "fault_injection")

Returns:

  • (Class) —

    a subclass of Proxy

Raises:

  • (ArgumentError) —

    if the kind is not "none" and has not been registered

# File 'lib/nonnative.rb', line 260

def proxy(kind)
  kind.nil? || kind == 'none' ? NoProxy : proxies.fetch(kind) { raise ArgumentError, "Unsupported proxy kind '#{kind}'" }
end

.reset ⇒ void

This method returns an undefined value.

Resets proxies for all currently started runners.

Raises:

  • (NoMethodError) —

    if called before start (because pool is nil)

# File 'lib/nonnative.rb', line 355

def reset
  Nonnative.pool.reset
end

.start ⇒ void

This method returns an undefined value.

Starts all configured services, servers, and processes, and waits for readiness.

Readiness is determined by attempting to connect to each runner's configured host/ports.

    raise Nonnative::StartError, errors.join("\n")
  end
end

.stop ⇒ void

This method returns an undefined value.

Stops all configured processes and servers, then services, and waits for shutdown.

  raise Nonnative::StopError, errors.join("\n") unless errors.empty?
end

.token(kind:, issuer:, key:, private_key:, expiration:) ⇒ Nonnative::Token

Builds a token generator for authenticating against a service under test.

The signing parameters are passed in directly; this is not coupled to any service's configuration format. The generated token string is ready for Nonnative::Header.auth_bearer.

Examples:

token = Nonnative.token(kind: 'jwt', issuer: 'iss', key: 'key-1', private_key: 'config/ed25519.pem', expiration: 3600)
Nonnative::Header.auth_bearer(token.generate(aud: 'GET /v1/things', sub: 'user-1'))

Parameters:

  • kind (String) —

    token kind, one of "jwt", "paseto", or "ssh"

  • issuer (String) —

    the iss claim (unused by the ssh kind)

  • key (String) —

    the key id (JWT kid header, PASETO kid footer, or SSH kid claim)

  • private_key (String) —

    path to the Ed25519 private key file (PKCS#8 PEM for jwt/paseto, OpenSSH format for ssh)

  • expiration (Integer) —

    token lifetime in seconds (drives exp)

Returns:

def token(kind:, issuer:, key:, private_key:, expiration:) = Nonnative::Token.new(kind:, issuer:, key:, private_key:, expiration:)
