Go SDK: Add TCP/TLS integration tests and examples

[mmodzelewski]

Summary

The Go SDK has TCP/TLS support implemented in foreign/go/client/tcp/tcp_core.go with configurable TLS options, but there are no integration tests for TLS connections and no TLS examples in examples/go/.

Current State

• TLS implementation: Present in tcp_core.go with config options:
  • tlsEnabled - Enable/disable TLS
  • tlsDomain - Domain for TLS (auto-extracts from address if not set)
  • tlsCAFile - Path to CA certificate file
  • tlsValidateCertificate - Toggle certificate validation (default: true)
• Integration tests: No TLS-specific integration tests exist (existing tests in foreign/go/ only cover serialization and benchmarks)
• Examples: No TLS-specific examples in examples/go/ (only basic consumer/producer examples exist)

Requirements

Integration Tests

• Add integration test(s) that start an Iggy server with TLS enabled and connect using the Go TCP client with TLS
• Use custom certificates from core/certs/ (iggy_ca_cert.pem, iggy_cert.pem, iggy_key.pem)
• Test scenarios:
  • Successful TLS connection with custom CA certificate
  • Connection failure when TLS is required but client doesn't use TLS
  • Basic message send/receive over TLS connection

Examples

• Add a TLS example in examples/go/ demonstrating:
  • How to configure the TCP client with TLS enabled
  • How to specify a custom CA certificate file
  • A simple producer/consumer flow over TLS

Reference

• Server TLS config env vars: IGGY_TCP_TLS_ENABLED=true, IGGY_TCP_TLS_CERT_FILE, IGGY_TCP_TLS_KEY_FILE
• Custom certs location: core/certs/
• C# TLS tests for reference: foreign/csharp/Iggy_SDK.Tests.Integration/IggyTlsConnectionTests.cs

I'd like to work on this issue.

Go SDK's TLS connection logic is NOT implemented yet (tcp_core.go line 328: 'TLS connection is not implemented yet'). The issue asks for integration tests and examples, but those require a working TLS implementation. Am I missing something?

@atharvalade Seems that I have missed this. I was pretty sure TLS is already implemented. I'll create a separate issue for that then.

@mmodzelewski no worries. works, you can assign that one to me as well. I can get to it in a few days unless someone else wants to take it up and can give a quicker TAT.

@mmodzelewski I opened it :)
