Test cases failing on rhel 7.6 ppc64le - Errors host not found in upstream "agentzh.org"

[SantoshMagdum]

Hi All,

I had build the nginx binary on rhel 7.6 ppc64le (version 1.17.1.1rc0) from source code - https://github.com/openresty/openresty. Please note that, I had copied and used ppc64le compiled LuaJIT code while building openresty (nginx). Below command I used to compile the openresty -

./configure --with-cc-opt="-DNGX_LUA_USE_ASSERT -DNGX_LUA_ABORT_AT_PANIC" --with-http_image_filter_module --with-http_dav_module --with-http_auth_request_module --with-poll_module --with-stream --with-stream_ssl_module --with-stream_ssl_preread_module --with-http_ssl_module --with-http_iconv_module --with-http_drizzle_module --with-http_postgres_module --with-http_addition_module --add-module=/usr/openresty/openresty_test_modules/nginx-eval-module --add-module=/usr/openresty/openresty_test_modules/replace-filter-nginx-module

And then tried to execute the test cases for 'srcache-nginx-module' like below -

[root stream-lua-nginx-module]# pwd /usr/openresty/openresty/openresty-1.17.1.1rc0/build/srcache-nginx-module-0.31 [root stream-lua-nginx-module]# PATH=/usr/openresty/openresty/openresty-1.17.1.1rc0/build/srcache-nginx-module-0.31:$PATH prove -r t

NOTE: The 'srcache-nginx-module' version downloaded with openresty bundle is 0.31.

But I am getting below kind of repeated errors -

nginx: [emerg] host not found in upstream "agentzh.org" in /usr/openresty/openresty/openresty-1.17.1.1rc0/build/srcache-nginx-module-0.31/t/servroot/conf/nginx.conf:45
nginx: [emerg] host not found in upstream "agentzh.org" in /usr/openresty/openresty/openresty-1.17.1.1rc0/build/srcache-nginx-module-0.31/t/servroot/conf/nginx.conf:45

Please help suggest if I need to export any specific environment/setup any additional service or should try any compiler flag/somehow increase timeout value to make these test cases pass?

Try running dig agentzh.org on your machine's command line?

[SantoshMagdum]

@agentzh - I see the ok response for dig tool and also received reply from agentzh.org for ping command - PING agentzh.org (188.166.239.230) 56(84) bytes of data. 64 bytes from 188.166.239.230 (188.166.239.230): icmp_seq=1 ttl=52 time=64.2 ms

Interestingly, openresty build with "--with-debug" option, errors for host agentzh.org are not coming but only below test case failure coming now -

   t/conditional-get.t ..... 19/54
   #   Failed test 'TEST 7: cache hit (I-U-S conditional GET, 412) - header Content-Length ok'
   #   at /usr/local/share/perl5/Test/Nginx/Socket.pm line 1009.
   #          got: '170'
   #     expected: '182'
   # Looks like you failed 1 test of 54.

[SantoshMagdum]

With the change of 'Content-Length:' from 182 to 170 the test case is passing. I shall make change and raise PR soon. Change made - Updated Content-Length: configuration to 170 from 182 in test case 7 - from file 'conditional-get.t' Content-Length: 170
