Better handling of late upstream creation.
Configuration with duplicate upstream blocks defined after first use, i.e.
like
server {
...
location / {
proxy_pass http://backend;
}
}
upstream backend { ... }
upstream backend { ... }
now correctly results in "duplicate upstream" error.
Additionally, upstream blocks defined after first use now handle various
server directive parameters ("weight", "max_fails", etc.). Previously
configuration like
server {
...
location / {
proxy_pass http://backend;
}
}
upstream backend {
server 127.0.0.1 max_fails=5;
}
incorrectly resulted in "invalid parameter "max_fails=5"" error.
