Subject: SSL: silenced warnings when building with OpenSSL 3.0.
X-Git-Tag: release-1.21.2~20
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=3df7efd34b26328c94149b6828ea22bb73ce00a2;p=nginx.git

SSL: silenced warnings when building with OpenSSL 3.0.

The OPENSSL_SUPPRESS_DEPRECATED macro is used to suppress deprecation warnings.
This covers Session Tickets keys, SSL Engine, DH low level API for DHE ciphers.

Unlike OPENSSL_API_COMPAT, it works well with OpenSSL built with no-deprecated.
In particular, it doesn't unhide various macros in OpenSSL includes, which are
meant to be hidden under OPENSSL_NO_DEPRECATED.
