test case for updating nginx-1.15.1 modules
View test_log_alibaba_tengine_pull_1105.md

Test Case:

  • Case failure:
    • sub_filter_slice.t: current tengine has its slice module, so this case is not run for nginx module.
    • limit_conn_complex.t: limit_req module is not updated.
    • index2.t: current tengine does not merge http://hg.nginx.org/nginx/rev/d91a8c4ac6bb.
    • userid.t: tengine refactor 404 page. It outputs URI in response, the URI has "expires" string, which makes case failed.

nginx source notes
View nginx_kqueue_event.txt
The available and post_available field of structure ngx_event_t is only used by KQUEUE.
Other event modules (epoll, poll and etc) donest care about it.
For read event, available means size of data ready to read.
For read event(listening event), available means size of listen backlog.
post_avalibale is only used for multi-thread & KQUEUE.
multi_accept directive doesn't matter for kqueue. (see http://forum.nginx.org/read.php?2,3638,3661)
