Nginx redis, select database not working?

I’m having problem with redis module: http://wiki.nginx.org/HttpRedis
(version 0.32 downloaded from mirror at
https://github.com/elcuervo/nginx_http_redis)

As I tried, variable $redis_db is never used and result always comes
from “default” - database 0.
Am I missing something in my config?

my nginx.conf (part of):
upstream { server 192.168.2.178:6379; keepalive 256 single;}

location /testredisselect0
{
default_type text/html;
set $redis_key “$uri?dbid=notdef”;
redis_pass redisbackend;
}

location /testredisselect1
{
default_type text/html;
set $redis_db “1”;
set $redis_key “$uri?dbid=1”;
redis_pass redisbackend;
}

curl “http://localhost/testredisselect0
curl “http://localhost/testredisselect1

result in redis monitor:
1307190385.099634 “select” “0”
1307190385.099688 “get” “/testredisselect0?dbid=notdef”
1307190387.739512 “select” “0”
1307190387.739561 “get” “/testredisselect1?dbid=1”

As I can see, command always issues select 0, although it should run
select 1 in second case.

Did that rev actually compile and make without issue for you? I was
using that module a while back and ended up commenting out the below
line inorder for it to build successfully.

/* static ngx_str_t ngx_http_redis_db = ngx_string(“redis_db”); */

I wasn’t using different redis db’s at the time and didn’t look into it
much. I bet pipelining with agentzh’s redis2 would work just fine. I
saw your post over in the parser thread, did you give that a try yet?

I don’t know anything about this URL. Original sources available

Patch.

@gregr401 I applied the patch to original redis module, as provided
by Sergey. It works great. Previous I used module from Git. Compiled OK.
Regarding Redis2: I use it when advanced processing is required
(pipeline, redis Lua script). When all I need is simple get with high
frequency I prefer strict C module.

@Sergey. Used original download url now and applied your patch. Work’s
great. Thanks again. Problem solved.

Result in redis monitor after patch applied.
