annotate src/http/ngx_http_upstream_round_robin.h @ 326:9fc4ab6673f9 NGINX_0_6_7
nginx 0.6.7
*) Change: now the paths specified in the "include",
"auth_basic_user_file", "perl_modules", "ssl_certificate",
"ssl_certificate_key", and "ssl_client_certificate" directives are
relative to directory of nginx configuration file nginx.conf, but
not to nginx prefix directory.
*) Change: the --sysconfdir=PATH option in configure was canceled.
*) Change: the special make target "upgrade1" was defined for online
upgrade of 0.1.x versions.
*) Feature: the "server_name" and "valid_referers" directives support
regular expressions.
*) Feature: the "server" directive in the "upstream" context supports
the "backup" parameter.
*) Feature: the ngx_http_perl_module supports the
$r->discard_request_body.
*) Feature: the "add_header Last-Modified ..." directive changes the
"Last-Modified" response header line.
*) Bugfix: if an response different than 200 was returned to an request
with body and connection went to the keep-alive state after the
request, then nginx returned 400 for the next request.
*) Bugfix: a segmentation fault occurred in worker process if invalid
address was set in the "auth_http" directive.
*) Bugfix: now nginx uses default listen backlog value 511 on all
platforms except FreeBSD.
Thanks to Jiang Hong.
*) Bugfix: a worker process may got caught in an endless loop, if an
"server" inside "upstream" block was marked as "down"; bug appeared
in 0.6.6.
*) Bugfix: now Solaris sendfilev() is not used to transfer the client
request body to FastCGI-server via the unix domain socket.
