Test case failures on rhel7.6 ppc64le platform

Hi All,

I had build the nginx binary on rhel 7.6 ppc64le (version 1.17.1.1rc0) from openresty source code - https://github.com/openresty/openresty
Please note that, I had copied and used ppc64le compiled LuaJIT source 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 'lua-resty-core' like below -

# pwd
/usr/santosh/openresty/openresty/openresty-1.17.1.1rc0/build/lua-resty-core-0.1.17
# prove -I/usr/santosh/openresty/test-nginx/lib/ -r t

NOTE: The lua-resty-core version downloaded from openresty bundle is 0.1.17.

But I am getting below kind of errors -

Around 8 test case failures related to timer manipulation -

t/balancer-timeout.t ............... 1/88

And other set of errors shows invalid index for 'opt' field -

t/count.t .......................... nginx: [error] init_by_lua error: init_by_lua:12: attempt to index field 'opt' (a nil value)
stack traceback:

Bailout called.  Further testing stopped:  TEST 1: module size - Cannot start nginx using command "nginx -p /usr/openresty/openresty/openresty-1.17.1.1rc0/build/lua-resty-core-0.1.17/t/servroot/ -c /usr/openresty/openresty/openresty-1.17.1.1rc0/build/lua-resty-core-0.1.17/t/servroot/conf/nginx.conf > /dev/null" (status code 256).

Please help suggest if I need to export any specific environment variable or should try any compiler flag/somehow increase timeout value to make these test cases pass.
Let me know if I should share more information which could help in resolving these test failures.

Start with t/balancer-timeout.t, t/balancer.t, and t/count.t, then inspect the reported failures through test-nginx/lib/Test/Nginx/Socket.pm. Reproduce the tests on RHEL 7.6 ppc64le with the stated OpenResty and LuaJIT versions, compare the timer, keepalive, and opt-field failures, and establish whether the result is a platform or build-configuration issue.
