comparison src/os/unix/ngx_atomic.h @ 160:73e8476f9142 NGINX_0_3_27

nginx 0.3.27 *) Change: the "variables_hash_max_size" and "variables_hash_bucket_size" directives. *) Feature: the $body_bytes_sent variable can be used not only in the "log_format" directive. *) Feature: the $ssl_protocol and $ssl_cipher variables. *) Feature: the cache line size detection for widespread CPUs at start time. *) Feature: now the "accept_mutex" directive is supported using fcntl(2) on platforms different from i386, amd64, sparc64, and ppc. *) Feature: the "lock_file" directive and the --with-lock-path=PATH autoconfiguration directive. *) Bugfix: if the HTTPS protocol was used in the "proxy_pass" directive then the requests with the body was not transferred.
