Stats Socket breaks with Boost 1.87

[robotastic]

The Stats Socket plugin stops working with Boost 1.87. The WebSocket library being used ( https://github.com/zaphoyd/websocketpp ) hasn't been updated in 4 years, so it is not likely this will be fixed soon. The best option is to probably pull Stats Socket from the build for now until a new library can be slotted in.

Issue from Websocketpp repo:
zaphoyd/websocketpp#1157

asio removed some previously deprecated facilities, see https://www.boost.org/doc/libs/1_87_0/doc/html/boost_asio/history.html, this's my patch https://github.com/microsoft/vcpkg/pull/42678/files#diff-359671c6dbccd346495bb59cd5f29605921ff4c4448e6a136a89d873438b0c60

I think I'll also need to update the simplestream plugin due to this issue. Here's a dump from GPT that explains what needs to change. I'll put this on my to-do list for simplestream and the same changes should be able to be applied to this plugin as well, I think.

In some c++ code I'm getting this error after updating to a newer version of Boost. I think this might be because of some deprecated stuff in asio. how can I fix it?

simplestream.cc:52:63: error: no member named 'from_string' in 'boost::asio::ip::address'
   52 |       stream.remote_endpoint = ip::udp::endpoint(ip::address::from_string(stream.address), stream.port);

The error occurs because boost::asio::ip::address::from_string has been deprecated and removed in newer versions of Boost.Asio. Instead, you should use boost::asio::ip::make_address, which is the modern replacement for creating an ip::address from a string.

Updated Code

Replace:

ip::address::from_string(stream.address)

With:

boost::asio::ip::make_address(stream.address)

So the full line becomes:

stream.remote_endpoint = ip::udp::endpoint(boost::asio::ip::make_address(stream.address), stream.port);

Why This Works
boost::asio::ip::make_address is the new function introduced to replace from_string. It is more consistent with modern C++ practices and aligns with the general direction of Boost.Asio.
Additional Notes
Error Handling:

boost::asio::ip::make_address may throw an exception if the address string is invalid. You can catch this exception and handle it appropriately.

try {
    auto address = boost::asio::ip::make_address(stream.address);
    stream.remote_endpoint = ip::udp::endpoint(address, stream.port);
} catch (const std::exception& e) {
    std::cerr << "Invalid address: " << stream.address << " - " << e.what() << std::endl;
}

Support for IPv4 and IPv6:

boost::asio::ip::make_address supports both IPv4 and IPv6 addresses, so your code will work seamlessly for either.
Documentation Reference:

You can refer to the Boost.Asio documentation for more details about make_address: Boost.Asio Documentation.
Conclusion
The boost::asio::ip::make_address function is a direct replacement for the deprecated boost::asio::ip::address::from_string. Update your code to use it, and handle exceptions if needed to ensure robust error handling for invalid addresses. Let me know if you encounter additional issues! 🚀

These errors indicate that the io_service type in Boost.Asio has been replaced with io_context in newer versions of Boost. The io_context class serves the same purpose as io_service but was introduced to better align with modern C++ practices.

Fixes for Each Error

1. Replace io_service with io_context
   Change all instances of io_service to io_context:

boost::asio::io_service my_tcp_io_service;

Becomes:

boost::asio::io_context my_tcp_io_context;

2. Update typedef for io_service
   If you’re typedefing io_service, update it to use io_context:

typedef boost::asio::io_service io_service;

Becomes:
typedef boost::asio::io_context io_context;

3. Update ip::udp::socket Constructor
   The ip::udp::socket constructor expects a reference to an io_context object instead of an io_service. Replace:

ip::udp::socket my_socket{my_io_service};

With:

ip::udp::socket my_socket{my_tcp_io_context};

Complete Updated Code Snippet
Here’s how the updated code might look:

#include <boost/asio.hpp>

namespace ip = boost::asio::ip;

int main() {
    // Create an io_context instance
    boost::asio::io_context my_tcp_io_context;

    // Create a UDP socket using the io_context
    ip::udp::socket my_socket{my_tcp_io_context};

    // Example usage
    ip::udp::endpoint endpoint(ip::make_address("127.0.0.1"), 12345);
    my_socket.open(endpoint.protocol());
    my_socket.bind(endpoint);

    return 0;
}

Why These Changes Are Necessary
io_service Deprecated:

boost::asio::io_service has been deprecated and removed in favor of boost::asio::io_context.
Consistent API:

Constructors like ip::udp::socket and other Asio components now expect io_context references instead of io_service.
Additional Tips
If your code uses asynchronous operations, ensure you call my_tcp_io_context.run() to process events in the io_context.
Summary of Changes
Replace io_service with io_context.
Update typedefs and variable declarations accordingly.
Ensure components like ip::udp::socket use the updated io_context.
With these updates, your code should be compatible with newer versions of Boost.Asio. Let me know if you encounter further issues! 🚀
