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/zenhttp-test/zenhttp-test.cpp | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'src/zenhttp-test/zenhttp-test.cpp') diff --git a/src/zenhttp-test/zenhttp-test.cpp b/src/zenhttp-test/zenhttp-test.cpp index b4b406ac8..0a6980462 100644 --- a/src/zenhttp-test/zenhttp-test.cpp +++ b/src/zenhttp-test/zenhttp-test.cpp @@ -1,6 +1,7 @@ // Copyright Epic Games, Inc.
