From 899b44eab259f32af5c6e3da342f430c654528ce Mon Sep 17 00:00:00 2001 From: Igor Sysoev Date: Thu, 12 May 2005 14:58:06 +0000 Subject: nginx-0.1.29-RELEASE import *) Feature: the ngx_http_ssi_module supports "include virtual" command. *) Feature: the ngx_http_ssi_module supports the condition command like 'if expr="$NAME"' and "else" and "endif" commands. Only one nested level is supported. *) Feature: the ngx_http_ssi_module supports the DATE_LOCAL and DATE_GMT variables and "config timefmt" command. *) Feature: the "ssi_ignore_recycled_buffers" directive. *) Bugfix: the "echo" command did not show the default value for the empty QUERY_STRING variable. *) Change: the ngx_http_proxy_module was rewritten. *) Feature: the "proxy_redirect", "proxy_pass_request_headers", "proxy_pass_request_body", and "proxy_method" directives. *) Feature: the "proxy_set_header" directive. The "proxy_x_var" was canceled and must be replaced with the proxy_set_header directive. *) Change: the "proxy_preserve_host" is canceled and must be replaced with the "proxy_set_header Host $host" and the "proxy_redirect off" directives, the "proxy_set_header Host $host:$proxy_port" directive and the appropriate proxy_redirect directives. *) Change: the "proxy_set_x_real_ip" is canceled and must be replaced with the "proxy_set_header X-Real-IP $remote_addr" directive. *) Change: the "proxy_add_x_forwarded_for" is canceled and must be replaced with the "proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for" directive. *) Change: the "proxy_set_x_url" is canceled and must be replaced with the "proxy_set_header X-URL http://$host:$server_port$request_uri" directive. *) Feature: the "fastcgi_param" directive. *) Change: the "fastcgi_root", "fastcgi_set_var" and "fastcgi_params" directive are canceled and must be replaced with the fastcgi_param directives. *) Feature: the "index" directive can use the variables. *) Feature: the "index" directive can be used at http and server levels. *) Change: the last index only in the "index" directive can be absolute. *) Feature: the "rewrite" directive can use the variables. *) Feature: the "internal" directive. *) Feature: the CONTENT_LENGTH, CONTENT_TYPE, REMOTE_PORT, SERVER_ADDR, SERVER_PORT, SERVER_PROTOCOL, DOCUMENT_ROOT, SERVER_NAME, REQUEST_METHOD, REQUEST_URI, and REMOTE_USER variables. *) Change: nginx now passes the invalid lines in a client request headers or a backend response header. *) Bugfix: if the backend did not transfer response for a long time and the "send_timeout" was less than "proxy_read_timeout", then nginx returned the 408 response. *) Bugfix: the segmentation fault was occurred if the backend sent an invalid line in response header; the bug had appeared in 0.1.26. *) Bugfix: the segmentation fault may occurred in FastCGI fault tolerance configuration. *) Bugfix: the "expires" directive did not remove the previous "Expires" and "Cache-Control" headers. *) Bugfix: nginx did not take into account trailing dot in "Host" header line. *) Bugfix: the ngx_http_auth_module did not work under Linux. *) Bugfix: the rewrite directive worked incorrectly, if the arguments were in a request. *) Bugfix: nginx could not be built on MacOS X. --- src/http/ngx_http_variables.h | 30 ++++++++++++++---------------- 1 file changed, 14 insertions(+), 16 deletions(-) (limited to 'src/http/ngx_http_variables.h') diff --git a/src/http/ngx_http_variables.h b/src/http/ngx_http_variables.h index bf80386cb..6624535aa 100644 --- a/src/http/ngx_http_variables.h +++ b/src/http/ngx_http_variables.h @@ -14,13 +14,13 @@ #include -#define NGX_HTTP_VARIABLE_NOT_FOUND (ngx_http_variable_value_t *) -1 +#define NGX_HTTP_VAR_NOT_FOUND (ngx_http_variable_value_t *) -1 -struct ngx_http_variable_value_s { +typedef struct { ngx_uint_t value; ngx_str_t text; -}; +} ngx_http_variable_value_t; typedef struct ngx_http_variable_s ngx_http_variable_t; @@ -28,30 +28,28 @@ typedef ngx_http_variable_value_t * (*ngx_http_get_variable_pt) (ngx_http_request_t *r, uintptr_t data); -struct ngx_http_variable_s { - ngx_str_t name; - ngx_uint_t index; - ngx_http_get_variable_pt handler; - uintptr_t data; -}; +#define NGX_HTTP_VAR_CHANGABLE 1 +#define NGX_HTTP_VAR_NOCACHABLE 2 -typedef struct { - ngx_str_t name; +struct ngx_http_variable_s { + ngx_str_t name; /* must be first to build the hash */ ngx_http_get_variable_pt handler; uintptr_t data; -} ngx_http_core_variable_t; + ngx_uint_t flags; +}; ngx_http_variable_t *ngx_http_add_variable(ngx_conf_t *cf, ngx_str_t *name, - ngx_uint_t set); -ngx_int_t ngx_http_get_variable_index(ngx_http_core_main_conf_t *cmcf, - ngx_str_t *name); + ngx_uint_t flags); +ngx_int_t ngx_http_get_variable_index(ngx_conf_t *cf, ngx_str_t *name); ngx_http_variable_value_t *ngx_http_get_indexed_variable(ngx_http_request_t *r, ngx_uint_t index); ngx_http_variable_value_t *ngx_http_get_variable(ngx_http_request_t *r, ngx_str_t *name); -ngx_int_t ngx_http_variables_init(ngx_cycle_t *cycle); + +ngx_int_t ngx_http_variables_add_core_vars(ngx_conf_t *cf); +ngx_int_t ngx_http_variables_init_vars(ngx_conf_t *cf); #endif /* _NGX_HTTP_VARIABLES_H_INCLUDED_ */ -- cgit
