<div class="section" id="bugs-fixed">
<h2>Bugs Fixed<a class="headerlink" href="#bugs-fixed" title="Permalink to this headline">¶</a></h2>
<p>1. Fixed a reference counting bug which would cause a daemon process to
crash if both <tt class="docutils literal"><span class="pre">home</span></tt> and <tt class="docutils literal"><span class="pre">python-path</span></tt> options were specified at the
same time with the <tt class="docutils literal"><span class="pre">WSGIDaemonProcess</span></tt> directive.</p>
<p>2. When using <tt class="docutils literal"><span class="pre">--https-only</span></tt> option with <tt class="docutils literal"><span class="pre">mod_wsgi-express</span></tt>, the
redirection from the <tt class="docutils literal"><span class="pre">http</span></tt> address to the <tt class="docutils literal"><span class="pre">https</span></tt> address was not
setting the correct port for <tt class="docutils literal"><span class="pre">https</span></tt>.</p>
</div>
<div class="section" id="features-changed">
<h2>Features Changed<a class="headerlink" href="#features-changed" title="Permalink to this headline">¶</a></h2>
<p>1. Changed the default Apache log level for <tt class="docutils literal"><span class="pre">mod_wsgi-express</span></tt> to
<tt class="docutils literal"><span class="pre">warn</span></tt> instead of <tt class="docutils literal"><span class="pre">info</span></tt>. This has been done avoid very noisy logs
when enabling secure HTTP connections. To set back to <tt class="docutils literal"><span class="pre">info</span></tt> level use
the <tt class="docutils literal"><span class="pre">--log-level</span></tt> option.</p>
<p>2. When specifying a service script with the <tt class="docutils literal"><span class="pre">--service-script</span></tt> option of
<tt class="docutils literal"><span class="pre">mod_wsgi-express</span></tt>, the home directory for the process will now be set to
the same home directory as used for the hosted WGSI application. Python
modules from the WSGI application will therefore be automatically found
when imported. Any directory paths added using <tt class="docutils literal"><span class="pre">--python-path</span></tt> option
will also be added as search directories for Python module imports, with
any <tt class="docutils literal"><span class="pre">.pth</span></tt> files in those directories also being handled. In addition,
the language locale and Python eggs directory used by the hosted WSGI
application will also be used for the service script.</p>
<p>3. When specifying <tt class="docutils literal"><span class="pre">--python-path</span></tt> option, when paths are now setup for
the WSGI application, they will be added in such a way that they appear at
the head of <tt class="docutils literal"><span class="pre">sys.path</span></tt> and any <tt class="docutils literal"><span class="pre">.pth</span></tt> files in those directories are
also handled.</p>
</div>
<div class="section" id="new-features">
<h2>New Features<a class="headerlink" href="#new-features" title="Permalink to this headline">¶</a></h2>
<p>1. Added the <tt class="docutils literal"><span class="pre">--directory-listing</span></tt> option to <tt class="docutils literal"><span class="pre">mod_wsgi-express</span></tt> to
allow automatic directory listings to be enabled when using the static file
application type and no explicit directory index file has been specified.</p>
<p>2. In addition to the convenience function of <tt class="docutils literal"><span class="pre">--ssl-certificate</span></tt> for
<tt class="docutils literal"><span class="pre">mod_wsgi-express</span></tt>, which allowed the SSL certificate and private key
file to be specified using one option by specifying the command file
name up to the extension, separate <tt class="docutils literal"><span class="pre">--ssl-certificate-file</span></tt> and
<tt class="docutils literal"><span class="pre">--ssl-certificate-key-file</span></tt> options are now also provided. These
would either both need to be specified, or the existing
<tt class="docutils literal"><span class="pre">--ssl-certificate</span></tt> option used, when specifying that secure HTTPS
connections should be used through having specified <tt class="docutils literal"><span class="pre">--https-port</span></tt>.</p>
<p>3. Added the <tt class="docutils literal"><span class="pre">--ssl-ca-certificate-file</span></tt> option to <tt class="docutils literal"><span class="pre">mod_wsgi-express</span></tt>.
If specified this should give the location of the file with any CA
certificates to be used for client authentication. As soon as this option
is provided, the client authentication will be required for the whole site.
This would generally be used in conjunction with the <tt class="docutils literal"><span class="pre">--https-only</span></tt>
option so that only a secure communication channel is being used.</p>
<p>If you do not wish for the whole site to required client authentication,
you can use the <tt class="docutils literal"><span class="pre">--ssl-verify-client</span></tt> option to specify sub URLs for
which client authentication should be performed.</p>
<p>4. Added the <tt class="docutils literal"><span class="pre">--ssl-environment</span></tt> option to <tt class="docutils literal"><span class="pre">mod_wsgi-express</span></tt> to enable
the passing of standard SSL variables in the WSGI environ dictionary passed
to the WSGI application.</p>
<p>5. Added the <tt class="docutils literal"><span class="pre">WSGITrustedProxies</span></tt> directive and corresponding option of
<tt class="docutils literal"><span class="pre">--trust-proxy</span></tt> to <tt class="docutils literal"><span class="pre">mod_wsgi-express</span></tt>. This works in conjunction with
the <tt class="docutils literal"><span class="pre">WSGITrustedProxyHeaders</span></tt> directive and <tt class="docutils literal"><span class="pre">--trust-proxy-header</span></tt>
option of <tt class="docutils literal"><span class="pre">mod_wsgi-express</span></tt>. When trusted proxies are specified, then
proxy headers will only be trusted if the request originated with a trusted
proxy. Further, any IP addresses corresponding to a proxy listed in the
<tt class="docutils literal"><span class="pre">X-Forwarded-For</span></tt> header will only be trusted if specified. When
determining the value for <tt class="docutils literal"><span class="pre">REMOTE_ADDR</span></tt> the IP preceding the last
recognised proxy the request passed through will be used and not simply the
first IP listed in the header. The header will be rewritten to reflect what
was honoured with client IPs of dubious origin discarded.</p>
