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:

Class Method Details

.clear ⇒ void

This method returns an undefined value.

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

Call this before reconfiguring Nonnative or starting a new lifecycle in the same Ruby process. start/stop are intended to manage one lifecycle for the current pool.

end

.configure {|config| ... } ⇒ void

This method returns an undefined value.

.go_argv(tools, output, exec, cmd, *params) ⇒ Array<String>

Builds a Go test executable argv array with optional profiling/trace/coverage flags.

Use this when passing argv entries directly to spawn.

Parameters:

    the test binary (or wrapper) to execute

  • cmd (String) —

    the command argument passed to the test binary

  • params (Array<String>) —

    extra parameter strings for the command

Returns:

  • (Array<String>) —

    executable argv entries

def go_argv(tools, output, exec, cmd, *params)
  Nonnative::GoExecutable.new(tools, exec, output).argv(cmd, *params)
end

.go_command(tools, output, exec, cmd, *params) ⇒ String

Builds a Go test executable command string with optional profiling/trace/coverage flags.

Use this when passing a command string directly to spawn.

Parameters:

  • tools (Array<String>) —

    enabled tool names (e.g. ["prof", "trace", "cover"])

  • output (String) —

    directory where outputs should be written

  • exec (String) —

    the test binary (or wrapper) to execute

  • cmd (String) —

    the command argument passed to the test binary

  • params (Array<String>) —

    extra parameter strings for the command

Returns:

  • (String) —

    executable command string

end

.grpc_health(host:, port:, service:, timeout: 1) ⇒ Nonnative::GRPCHealth

Returns a client helper for the standard gRPC health checking protocol.

Parameters:

  • host (String) —

    gRPC server host

  • port (Integer) —

    gRPC server port

  • service (String) —

    gRPC health service name

  • timeout (Numeric) (defaults to: 1) —

    default call timeout in seconds

Returns:

# File 'lib/nonnative.rb', line 207

def grpc_health(host:, port:, service:, timeout: 1) = Nonnative::GRPCHealth.new(host: host, port: port, service: service, timeout: timeout)

.log_lines(path, predicate) ⇒ Array<String>

Reads a file and returns only lines matching the given predicate.

Parameters:

  • path (String) —

    file path to read

  • predicate (#call) —

    callable that receives a line and returns truthy/falsey

Returns:

  • (Array<String>) —

    matching lines

# File 'lib/nonnative.rb', line 163

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

.logger ⇒ Logger

Returns the gem logger (memoized).

The logger writes to the path configured at Nonnative::Configuration#log.

Returns:

  • (Logger)

# File 'lib/nonnative.rb', line 154

def logger

end

.observability ⇒ Nonnative::Observability

Returns an HTTP client for common health/readiness endpoints.

Returns:

# File 'lib/nonnative.rb', line 198

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 214

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 226

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 321

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.
