nginx-0.1.5-RELEASE import *) Bugfix: on Solaris and Linux there may be too many "recvmsg() returned not enough data" alerts. *) Bugfix: there were the "writev() failed (22: Invalid argument)" errors on Solaris in proxy mode without sendfile. On other platforms that do not support sendfile at all the process got caught in an endless loop. *) Bugfix: segmentation fault on Solaris in proxy mode and using sendfile. *) Bugfix: segmentation fault on Solaris. *) Bugfix: on-line upgrade did not work on Linux. *) Bugfix: the ngx_http_autoindex_module module did not escape the spaces, the quotes, and the percent signs in the directory listing. *) Change: the decrease of the copy operations. *) Feature: the userid_p3p directive.
