Migrate to libmicrohttpd 1.0.0 API with new features#370
Open
Conversation
Raise minimum libmicrohttpd requirement to 1.0.0 and migrate all deprecated APIs to their v3 replacements: - Basic Auth: MHD_basic_auth_get_username_password3, MHD_queue_basic_auth_required_response3 with UTF-8 support - Digest Auth: MHD_digest_auth_check3, MHD_digest_auth_check_digest3, MHD_queue_auth_required_response3 with SHA-512/256, userhash, nonce binding, and structured digest_auth_result enum Add new response types: empty_response, pipe_response, iovec_response. Add external event loop integration (run, run_wait, get_fdset, get_timeout, add_connection), daemon management (quiesce, get_listen_fd, get_active_connections, get_bound_port), and numerous new daemon options (listen_backlog, address_reuse, tcp_fastopen_queue_size, turbo, etc.). Add conditional WebSocket support via libmicrohttpd_ws. Add utility functions: reason_phrase, is_feature_supported, get_mhd_version.
Document WebSocket support, new response types (empty, iovec, pipe), external event loop integration, daemon introspection methods, new server configuration options (turbo, no_listen_socket, suppress_date_header, etc.), enhanced TLS options, updated digest authentication API with SHA-256/SHA-512/256 and fine-grained result codes, and new http_utils utility methods.
New example files: - empty_response_example: 204 No Content and HEAD-only responses - iovec_response_example: scatter-gather response from multiple buffers - pipe_response_example: streaming response from a pipe fd - websocket_echo: WebSocket echo server with on_open/on_message/on_close - daemon_info: daemon introspection (bound port, listen fd, http_utils) - external_event_loop: driving the server with run_wait() and quiesce() - turbo_mode: high-performance config with turbo, suppressed date header, TCP Fast Open, and listen backlog All examples are added to the Other Examples section of the README with inline code, test commands, and links to the source files.
