I made a new version of my patch. The patch still add the -p prefix but:
1- in auto/options, I've set the following variables:
+NGX_PREFIX_CONF_PATH=conf/nginx.conf
+NGX_PREFIX_ERROR_LOG_PATH=logs/error.log
+NGX_PREFIX_PID_PATH=logs/nginx.pid
+NGX_PREFIX_LOCK_PATH=logs/nginx.lock
+NGX_PREFIX_HTTP_CLIENT_TEMP_PATH=client_body_temp
+NGX_PREFIX_HTTP_PROXY_TEMP_PATH=proxy_temp
+NGX_PREFIX_HTTP_FASTCGI_TEMP_PATH=proxy_temp
+NGX_PREFIX_HTTP_LOG_PATH=logs/access.log
2- in auto/options I use them in remplacement of RAW string, for exemple:
- NGX_CONF_PATH=$NGX_PREFIX/conf/nginx.conf
+ NGX_CONF_PATH=$NGX_PREFIX/$NGX_PREFIX_CONF_PATH
3- 1) and 2) change nothing, except that default relative paths are in
variable now
4- In configure, I export those variables
5- in each source file in which one of thoses defined variable are
used, I changed it to
5a- if -p was not specified at runtime, nothing change. Use
NGX_PID_PATH and NGX_PREFIX_PID_PATH is not used at all.
5b- if -p was specified at runtime, so don't use NGX_PID_PATH but "-p
parameter"/NGX_PREFIX_PID_PATH
6- If the -p parameter doesn't finish with a '/' char, then add it (I
didn't take care of windows path yet)
I tried to make this patch clear and correct. It seams to work. But I
didn't have time to test many features like ("ssl_certficate*", and
"auth_basic_user_file). I'll try that tonight or tomorow.
Hope this help.
