Changes with nginx 0.7.7 30 Jul
2008

*) Change: now the EAGAIN error returned by connect() is not

considered
as temporary error.

*) Change: now the $ssl_client_cert variable value is a certificate
   with TAB character intended before each line except first one; an
   unchanged certificate is available in the $ssl_client_raw_cert
   variable.

*) Feature: the "ask" parameter in the "ssl_verify_client"

directive.

*) Feature: byte-range processing improvements.
   Thanks to Maxim D..

*) Feature: the "directio" directive.

*) Feature: MacOSX 10.5 sendfile() support.

*) Bugfix: now in MacOSX and Cygwin locations are tested in case
   insensitive mode; however, the compare is provided by single-byte
   locales only.

*) Bugfix: mail proxy SSL connections hanged, if select, poll, or
   /dev/poll methods were used.

*) Bugfix: UTF-8 encoding usage in the ngx_http_autoindex_module.

What is this “directio” directive? I didn’t find anything searching
the list archive.

directio [off|size]
http/server/location level
default off

The directive enables O_DIRECT or F_NOCACHE (Mac OS X) options for
files open for reading if their size is bigger than specified in
directive.

Example:

 directio  4m;
 sendfile  off;
4

Why would one use directio vs sendfile? Why would/should they be
mutually exclusive?

The main sendfile advantage is that it uses pages of cached files.
directio disables file caching. This example should be corrected as

  sendfile  on;
  directio  4m;

Then files up to 4M would have good chances to be cached in VM.
