From d0a07e555577dcd4a8f55f1b45d9e8e4e6366ab7 Mon Sep 17 00:00:00 2001 From: Stefan Boberg Date: Tue, 10 Mar 2026 17:27:26 +0100 Subject: HttpClient using libcurl, Unix Sockets for HTTP. HTTPS support (#770) The main goal of this change is to eliminate the cpr back-end altogether and replace it with the curl implementation. I would expect to drop cpr as soon as we feel happy with the libcurl back-end. That would leave us with a direct dependency on libcurl only, and cpr can be eliminated as a dependency. ### HttpClient Backend Overhaul - Implemented a new **libcurl-based HttpClient** backend (`httpclientcurl.cpp`, ~2000 lines) as an alternative to the cpr-based one - Made HttpClient backend **configurable at runtime** via constructor arguments and `-httpclient=...` CLI option (for zen, zenserver, and tests) - Extended HttpClient test suite to cover multipart/content-range scenarios ### Unix Domain Socket Support - Added Unix domain socket support to **httpasio** (server side) - Added Unix domain socket support to **HttpClient** - Added Unix domain socket support to **HttpWsClient** (WebSocket client) - Templatized `HttpServerConnectionT` and `WsAsioConnectionT` to handle TCP, Unix, and SSL sockets uniformly via `if constexpr` dispatch ### HTTPS Support - Added **preliminary HTTPS support to httpasio** (for Mac/Linux via OpenSSL) - Added **basic HTTPS support for http.sys** (Windows) - Implemented HTTPS test for httpasio - Split `InitializeServer` into smaller sub-functions for http.sys ### Other Notable Changes - Improved **zenhttp-test stability** with dynamic port allocation - Enhanced port retry logic in http.sys (handles ERROR_ACCESS_DENIED) - Fatal signal/exception handlers for backtrace generation in tests - Added `zen bench http` subcommand to exercise network + HTTP client/server communication stack --- src/zenserver/zenserver.cpp | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'src/zenserver/zenserver.cpp') diff --git a/src/zenserver/zenserver.cpp b/src/zenserver/zenserver.cpp index 88b85d7d9..49ae1b6ff 100644 --- a/src/zenserver/zenserver.cpp +++ b/src/zenserver/zenserver.cpp @@ -23,6 +23,7 @@ #include #include #include +#include #include #include #include @@ -146,6 +147,14 @@ ZenServerBase::Initialize(const ZenServerConfig& ServerOptions, ZenServerState:: EnqueueSigIntTimer(); + // Configure HTTP client back-end + + const std::string HttpClientBackend = ToLower(ServerOptions.HttpClient.Backend); + zen::SetDefaultHttpClientBackend(HttpClientBackend); + ZEN_INFO("Using '{}' as HTTP client backend", HttpClientBackend); + + // Initialize HTTP server + m_Http = CreateHttpServer(ServerOptions.HttpConfig); int EffectiveBasePort = m_Http->Initialize(ServerOptions.BasePort, ServerOptions.DataDir); if (EffectiveBasePort == 0) -- cgit v1.2.3
