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.
