Changes with nginx 1.5.3 30 Jul 2013

  • ) Change in internal API: now u->length defaults to -1 if working with backends in unbuffered mode.
  • ) Change: now after receiving an incomplete response from a backend server nginx tries to send an available part of the response to a client, and then closes client connection.
  • ) Bugfix: a segmentation fault might occur in a worker process if the ngx_http_spdy_module was used with the “client_body_in_file_only” directive.
  • ) Bugfix: the “so_keepalive” parameter of the “listen” directive might be handled incorrectly on DragonFlyBSD. Thanks to Sepherosa Ziehau.
  • ) Bugfix: in the ngx_http_xslt_filter_module.
  • ) Bugfix: in the ngx_http_sub_filter_module.
