From cfbe03a6e035ab3cce5f04962cddd06bd414dcea Mon Sep 17 00:00:00 2001 From: "Richard J. Moore" Date: Thu, 23 Mar 2017 12:43:22 +0100 Subject: QSslSocket: OpenSSL 1.1 backend MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch-set implements a new QSslSocket backend based on OpenSSL 1.1. 1. General. The code in this patch was organized to achieve these (somewhat contradicting) objectives: - keep the new code free of #if-ery, as far as possible; - make it easy to clean away dead code when we're eventually able to retire out-dated OpenSSL versions; - reduce the amount of code duplication. If changes in some file/component were insignificant (~5 one-liners per file), we still use pp-checks like: #if QT_CONFIG(opensslv11) ... #else ... #endif - the logic is simple and it's still easy to clean the code if we remove the legacy back-end. Where it saved #if-ery, we also introduced 'forward-compatible' macros implementing equivalents of 1.1 functions using older OpenSSL. In case some class contains a lot of version-specific ifdefs (particularly where nested #if-ery was complex) we choose to split code into: "pre11" h/cpp files, "shared" h/cpp files (they preserve their original names, e.g qsslsocket_openssl.cpp) and "11" h/cpp files. If in future we remove the legacy back-end, "pre11" should be removed; "shared" and "11" parts - merged. 2. Configuration. We introduced a new feature 'opensslv11' which complements the pre-existing 'openssl' and 'openssl-linked' features. The 'opensslv11' feature is enabled by a simple test which either compiles successfully or ends in a compilation error, depending on a value of the OPENSSL_VERSION_NUMBER constant. If the feature was enabled, we also append an additional compilation flag -DOPENSSL_API_COMPAT=0x10100000L to make sure our new code does not contain deprecated structures, function calls, macro-invocations from OpenSSL < 1.1.
