nginx: src/http/modules/proxy/ngx_http_proxy

annotate src/http/modules/proxy/ngx_http_proxy_upstream.c @ 473:8e8f3af115b5 release-0.1.11

nginx-0.1.11-RELEASE import *) Feature: the worker_priority directive. *) Change: both tcp_nopush and tcp_nodelay directives affect the transferred response. *) Bugfix: nginx did not call initgroups(). Thanks to Andrew Sitnikov and Andrei Nigmatulin. *) Change: now the ngx_http_autoindex_module shows the file size in the bytes. *) Bugfix: the ngx_http_autoindex_module returned the 500 error if the broken symlink was in a directory. *) Bugfix: the files bigger than 4G could not be transferred using sendfile. *) Bugfix: if the backend was resolved to several backends and there was an error while the response waiting then process may got caught in an endless loop. *) Bugfix: the worker process may exit with the "unknown cycle" message when the /dev/poll method was used. *) Bugfix: "close() channel failed" errors. *) Bugfix: the autodetection of the "nobody" and "nogroup" groups. *) Bugfix: the send_lowat directive did not work on Linux. *) Bugfix: the segmentation fault occurred if there was no events section in configuration. *) Bugfix: nginx could not be built on OpenBSD. *) Bugfix: the double slashes in "://" in the URI were converted to ":/".
