This patch changes the registration of the following keywords to be unconditional: - ssl-dh-param-file - ssl-engine - ssl-propquery, ssl-provider, ssl-provider-path - ssl-default-bind-curves, ssl-default-server-curves - ssl-default-bind-sigalgs, ssl-default-server-sigalgs - ssl-default-bind-client-sigalgs, ssl-default-server-client-sigalgs Instead of excluding them at compile time via #ifdef guards in the keyword registration table, their parsing functions now check feature availability at runtime and return a descriptive error when the feature is missing. For features controlled by the SSL library (providers, curves, sigalgs, DH), the error message includes the actual OpenSSL version string via OpenSSL_version(OPENSSL_VERSION), so users can immediately identify which library they are running rather than seeing cryptic internal macro names. For ssl-dh-param-file, the message also includes "(no DH support)" as a hint, since OPENSSL_NO_DH can be set either by an OpenSSL build or by HAProxy itself in certain configurations. For ssl-engine, which depends on a HAProxy build-time flag (USE_ENGINE), the message retains the flag name as it is more actionable for the user. This addresses issue https://github.com/haproxy/haproxy/issues/3246.
HAProxy
HAProxy is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
Installation
The INSTALL file describes how to build HAProxy. A list of packages is also available on the wiki.
Getting help
The discourse and the mailing-list are available for questions or configuration assistance. You can also use the slack or IRC channel. Please don't use the issue tracker for these.
The issue tracker is only for bug reports or feature requests.
Documentation
The HAProxy documentation has been split into a number of different files for ease of use. It is available in text format as well as HTML. The wiki is also meant to replace the old architecture guide.
