Merging r3986, r4006, r4007, r4073: Request body related fixes: *) Always set timer in discard body handler, this fixes the cases when request for static file is redirected by error_page to an SSI page. *) Correctly set body if it's preread and there are extra data. Previously all available data was used as body, resulting in garbage after real body e.g. in case of pipelined requests. Make sure to use only as many bytes as request's Content-Length specifies. *) Fix body with request_body_in_single_buf. If there were preread data and request body was big enough first part of the request body was duplicated. See report here: http://mailman.nginx.org/pipermail/nginx/2011-July/027756.html *) Bugfix: read event was not blocked after reading body. Read event should be blocked after reading body, else undefined behaviour might occur on additional client activity. This fixes segmentation faults observed with proxy_ignore_client_abort set.
