Hello! Here is a patch series which fixes several issues with AIO (threaded IO) and some related issues, initially inspired by ticket #2555.
Most notably, it fixes various issues with incorrect request termination with subrequests when an AIO operation is running in another subrequest, as observed in ticket #2555 (first patch). Additionally, it fixes an issue with request termination due to filter finalization with ngx_event_pipe() on stack (second patch), fixes incorrect alerts about open sockets left when SIGQUIT is followed by SIGTERM (third patch), and introduces guard timers for AIO operations to prevent premature shutdown of worker processes (forth patch, ticket #2162). In tests this fixes two alerts as observed with aio_write, in image_filter_finalize.t and in proxy_cache_use_stale.t: image_filter_finalize.t (Wstat: 0 Tests: 5 Failed: 0) TODO passed: 4 proxy_cache_use_stale.t (Wstat: 0 Tests: 36 Failed: 0) TODO passed: 35 Review and testing appreciated. -- Maxim Dounin http://mdounin.ru/ _______________________________________________ nginx-devel mailing list nginx-devel@nginx.org https://mailman.nginx.org/mailman/listinfo/nginx-devel
