File 0019-CPPXT-110-OpenSSL-1.1-makes-X509_STORE_CTX-and-X509_.patch of Package xmltooling
From fb43000e099683aae9188f0197978437e62163c7 Mon Sep 17 00:00:00 2001 From: Rod Widdowson <rdw@steadingsoftware.com> Date: Thu, 14 Jul 2016 14:10:50 +0100 Subject: [PATCH 19/31] CPPXT-110 OpenSSL 1.1 makes X509_STORE_CTX and X509_CRL opaque https://issues.shibboleth.net/jira/browse/CPPXT-110 Where possible we use the setters and getters. In some cases the setters and getters have had their names changed and so we hide this inside the new header file security/impl/OpenSSLSupport.h We are keeping the header file inside impl for now. In PKIXPathValidator we used to have a class on the stack. Instead security/impl/OpenSSLSupport (.h and .cpp) invent a new RAII class to abstract the allocation away. The class also has a couple of methods which hide the changes to setter/getter names (X509_STORE_CTX_set0_trusted_stack and X509_STORE_CTX_get0_chain) Also in PKIXPathValidator a series of macros around X509_CRL have become a function without a const parameter so we conditionalize a local variable's 'const' nesss.
