<title>Description</title>
<para><command>apachectl</command> is a front end to the Apache HyperText
Transfer Protocol (HTTP) server. It is designed to help the
administrator control the functioning of the Apache
<command>httpd</command> daemon.</para>
<para>The <command>apachectl</command> script takes one-word arguments like
<option>start</option>,
<option>restart</option>, and
<option>stop</option>, and translates them
into appropriate signals to <command>httpd</command>.</para>
<para>The <command>apachectl</command> script returns a 0 exit value on
success, and &gt;0 if an error occurs.</para>
<refsect2 id="compatibility">
<title>Compatibility</title>
<para>The version of <command>apachectl</command> used on this
system is a replacement script intended to be mostly (but not
completely) compatible with version provided with
<emphasis>Apache httpd</emphasis>. This
<command>apachectl</command> mostly acts as a wrapper around
<command>systemctl</command> and manipulates the
<command>systemd</command> service for <command>httpd</command>.
The interface to the <emphasis>Apache</emphasis> version of
<command>apachectl</command> is described at <ulink
url="https://httpd.apache.org/docs/2.4/programs/apachectl.html"/>.</para>
<para>The following differences are present in the version of
<command>apachectl</command> present on this system:
<itemizedlist>
<listitem><para>Option arguments passed when starting
<command>httpd</command> are not allowed. These should be
configured in the systemd service directly (see <citerefentry><refentrytitle>httpd.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>).</para></listitem>
<listitem><para>The <command>"fullstatus"</command> option is
not available.</para></listitem>

not use or rely on the running server's
<emphasis>server-status</emphasis> output.</para></listitem>

effect is that old log files will not be closed immediately. This

+Before OpenSSL 1.1.1, even though the Server Name Indication (SNI) allowed to

+handshake, the <code class="directive">SSLProtocol</code> of each (name-based) virtual

From ced24e032ebe185a2d885fa309d6de47668ba31e Mon Sep 17 00:00:00 2001
From: Yann Ylavic <ylavic@apache.org>
Date: Fri, 26 Jun 2020 10:21:19 +0000
Subject: [PATCH] Merge r1878280 from trunk:
mod_proxy_http: don't strip EOS when spooling request body to file.
To prevent stream_reqbody() from sending the FILE and FLUSH bucket in separate
brigades, and thus apr_file_setaside() to trigger if network congestion occurs
with the backend, restore the EOS in spool_reqbody_cl() which was stripped
when spooling the request body to a file.
Until APR r1878279 is released (and installed by users), apr_file_setaside()
on a temporary file (mktemp) will simply drop the file cleanup, leaking the
fd and inode..
This fixes BZ 64452.
