I'm seeing the following all over my in my nginx error.log file. And the file size grows very quickly. built nginx-clojure module. nginx version is 1.11.6

1. Write a handler to return the response in a certain time (60s).
2. start nginx-clojure server with correct configurations
3. curl the url
4. do nginx-clojure reload to refresh configurations

Except: The curl should get the correct response.

Actual: The curl failed with empty response with tcpdump, nginx-clojure reset the connection after the handler return.

Hi Xfeep,

I currently have a problem with Nginx-Clojure and am hoping you can help. I am using Nginx-Clojure as a Java-ring-handler to communicate between our Frontend & Database.

Their are several Java methods which I call via a HTTP request to recieve data from an old DB, parse it & send send it to our new DB. This would be our heaviest process & once completed the Memory never gets freed from the Nginx Workers. Basically after a few days Nginx will crash due to lack of memory.

I have checked over as much as possible over the last 2 months to find the problem. The Java code itself is unfortunately not the problem. Examples of the code can be given if necessary.

I am stumped and need help :(

If any details are missing I will get them for you: Nginx Version: 1.8.0 Nginx-Clojure: 0.4.4 Centos 7 (Docker Container)

Nginx Config: See attachment' nginx.conf.txt

Tried to set these via jvm_options (nginx.conf) but unable to do so and worker process is not spawned

-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=true -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=<port#> -Djava.rmi.server.hostname=<server-ip>

It should accept them perhaps combination ?

Creates the following message in errors.log jvm may be mad for wrong options!

looked in /tmp and there is thread dump.

I deployed nginx-clojure as docker container.

I get always the following error:

Error: Could not find or load main class nginx.clojure.DiscoverJvm

Any idea?? Thanks in advance

rewrite_handler_name & rewrite_handler_code don't work without handler_code or handler_name

This example does not work

        set $destination "should_get_overwritten";
        location / {
           resolver 8.8.8.8;
           handler_type 'java';
           rewrite_handler_name 'my.ProxyHandler';
           proxy_pass $destination;
        }

But old directive clojure & clojure_rewrite_code works. e.g. This example works

        set $destination "should_get_overwritten";
        location / {
           resolver 8.8.8.8;
           clojure;
           clojure_rewrite_code '
           (do 
                      (require \'[my.clj-handler :as m])
                      m/clj-proxy-handler)';        
           proxy_pass $destination;
        }

Thanks Eric Kubacki for finding this bug.

Hi, I am very interested in using the async sockets you provide to the client libs. If I use them with core.async, will core.async still initialize its own thread pool and run its go blocks there? If not, could you make an example of the async sockets used in Clojure?

I have tried to compile nginx-clojure via Ubuntu 12.04's build tool, but everytime I try to hit the /clojure location, I have a Method not found exception.

Oddly, I have a 16KB .jar file, compared to the binary one which is 42KB. I have placed the jars into /etc/nginx/jars.

Exception in thread "main" java.lang.NoSuchMethodError: Method nginx.clojure.NginxClojureRT.ngx_create_file_buf(JJJI)J not found 2014/01/19 16:45:30 [error] 31648#0: can not initialize jvm memory util

Any Ideas?

Hi,

I am having a problem with running the external "groovy" example routine. Using the inline option it works fine. I have checked permissions, and the code itself which is straight out of the Nginx 3rd Party modules example list. When trying to run this via an external routine it fails. I have checked paths and copied the external code into a mytest subdirectory as from another issue logged.

    This section fails
    location /groovy {
            handler_type 'groovy';
            handler_name 'mytest.HelloGroovy';
    }

    This section "Works" when un-commented:
    #location /groovy {
    #       handler_type 'groovy';
    #       handler_code '
    #       import nginx.clojure.java.NginxJavaRingHandler;
    #       import java.util.Map;
    #               public class HelloGroovy implements NginxJavaRingHandler {
    #                       public Object[] invoke(Map<String, Object> request){
    #                               return [200, //http status 200
    #                                       ["Content-Type":"text/html"], //headers map
    #                                       "Hello, Groovy & NGINX!"]; //response body can be string, File or Array/Collection of them
    #                       }
    #               }
    #       ';
    #}

which produces 2017/12/22 11:11:21 [error] 23789#23789: invalid groovy content_handler code : mytest.HelloGroovy 2017/12/22 11:11:22 [alert] 23787#23787: worker process 23789 exited with fatal code 2 and cannot be respawned

Would be grateful if someone could advise.

NginxEmbedServer spins off with old version of compojure, which still has the middleware ordering bug (https://github.com/weavejester/compojure/pull/157).

nginx-clojure for some reason depends on compojure 1.1.6, which is really ancient.

2016-04-01 22:15:50.328 nginx-macosx[7910:1036829] The application with bundle ID (null) is running setugid(), which is not allowed. 2016/04/01 22:15:50 [error] 7911#0: jvm may be mad for wrong options!

Bumps spring-web from 5.3.19 to 6.0.0.

Dependabot will resolve any conflicts with this PR as long as you don't alter it yourself. You can also trigger a rebase manually by commenting @dependabot rebase.

To run nginx-clojure on JDK 1.17, 1.19 we need add jvm options in nginx.conf, e.g.

    jvm_options "--add-opens=java.base/java.lang=ALL-UNNAMED";
    jvm_options "--add-opens=java.base/sun.nio.cs=ALL-UNNAMED";
    jvm_options "--add-opens=java.base/sun.nio.ch=ALL-UNNAMED";

Hi,Zhang! Will it be possible to support the use of content_handler, rewrite_handler, access_handler, header_filter, body_filter and other methods in the context of http and server level in the future? Just like the openresty's access_by_lua_block、header_filter_by_lua_block、body_filter_by_lua_block etc.

Since the release version does not support the ip_hash feature, I want to try to compile.

nginx-1.23.1
pcre-8.45
openssl-3.0.5
msvc cl 19.29
perl-5.32.1

I successfully compiled nginx.exe with this environment.

Progress

I execute /nginx-clojure-embed/configure-win32 , it output ..

But the current version of nginx no longer exists lib/sha1/makefile.msvc so idk how do it, Or can you provide support ip_hash nginx (dll/so/dylib) ?

Hello!

I'm trying to create a rewrite filter that will add a new header that gets passed down to the proxy endpoint. It appears that the headers are read only for the filter. Is this intended, or was there a way to add this I just haven't been able to discover?

Thanks!
