<h2>
<a NAME="req"></a>Requirements</h2>
Apache 1.3 requires MPE/iX 6.0 or greater.&nbsp; It will NOT run on earlier
releases of MPE/iX.&nbsp; The following MPE/iX patches (or their superseding
descendants) are relevant to Apache:
<ul>
<li>
MPE/iX 6.0:</li>

<ul>
<li>
MPEKXT3B - fixes an MPE bug that results in transient "permission denied"
errors being returned by the server to the browser.</li>

<li>
MPELX36A - enhances the kill() function so that MPE users with SM capability
can send signals to Apache for shutdown, restart, etc.</li>

<li>
MPELX44C - fixes an MPE bug that prevents DSO modules from being dynamically
loaded.</li>

<li>
MPELX51C - enhances the kill() function so that Apache can use it when
the Apache parent UID is different from the Apache children UID (strongly
recommended).</li>

<li>
NSTxxxxx - the latest network transport patch should always be installed
when using TCP/IP applications such as Apache.</li>
</ul>

<li>
MPE/iX 6.5:</li>

<ul>
<li>
MPELX44D - fixes an MPE bug that prevents DSO modules from being dynamically
loaded.</li>

<li>
MPELX51D - enhances the kill() function so that Apache can use it when
the Apache parent UID is different from the Apache children UID (strongly
recommended).</li>

<li>
NSTxxxxx - the latest network transport patch should always be installed
when using TCP/IP applications such as Apache.</li>
</ul>
</ul>

<hr WIDTH="100%"></h2>

<h2>
<a NAME="implement"></a>Implementation Considerations</h2>
While MPE has a very good POSIX implementation that enables fairly simple
porting of Unix applications such as Apache, there are some Unix concepts
which just don't exist or aren't fully implemented in MPE, and so this
may force some functionality changes in the package being ported.
<h3>
Significant MPE vs. Unix OS differences</h3>

<ul>
<li>
MPE lacks the concept of a Unix UID=0 root user with special privileges.&nbsp;
Where Unix functions require a user to be executing as root, MPE requires
the user to be executing in priv mode, so the program file must be linked
with PM (Priv Mode) capability, and the Unix function calls must be bracketed
by GETPRIVMODE() and GETUSERMODE() calls.&nbsp; The following Unix functions
used by Apache are affected:</li>

<ul>
<li>
bind() for ports less than 1024</li>

<li>
setgid()</li>

<li>
setuid()</li>
</ul>

<li>
MPE's support for UIDs and GIDs is more limited than Unix.&nbsp; Every
MPE account maps to a unique GID.&nbsp; Each MPE account can contain multiple
MPE users, and every MPE user maps to a unique UID (UID 0 is not supported).&nbsp;
The current UID for a process must correspond to an MPE user within the
MPE account that corresponds to the current GID of the process.</li>

<li>
MPE child processes cannot survive the death of their parent.&nbsp; When
the parent terminates, any remaining children will be killed.</li>

<li>
MPE doesn't initialize the envp parameter when invoking the main() of a
new process.&nbsp; Use the global variable environ instead of envp.</li>

<li>
MPE link() exists, but always returns EIMPL.&nbsp; Use rename() or symlinks
instead of hard links.</li>

<li>
MPE doesn't allow the @ character in filenames.</li>

<li>
MPE lacks support for TCP_NODELAY, but that's the default anyway.</li>

<li>
MPE lacks support for SO_KEEPALIVE.</li>

<li>
MPE lacks support for process groups.</li>

<li>
MPE inetd only passes stdin (and NOT stdout) to the invoked service.&nbsp;
But you can write to stdin just fine.</li>
</ul>

<h3>
Major Apache functionality issues</h3>

<ul>
<li>
Beginning with HP-supported Apache 1.3.9 and HP WebWise MPE/iX Secure Web
Server A.01.00 (based on Apache 1.3.9), the User and Group directives in
httpd.conf are now unconditionally executed as corresponding setuid()/setgid()
calls.&nbsp; Previously this was only done if HTTPD was being run as MANAGER.SYS.&nbsp;
This functionality change was submitted back to the 1.3.13-dev source tree
at www.apache.org.&nbsp; The Apache for Unix behavior is to only honor
User and Group if running as root.</li>

<li>
Beginning with HP-supported Apache 1.3.9 and HP WebWise MPE/iX Secure Web
Server A.01.00 (based on Apache 1.3.9), the SVIPC shared memory macros
SHM_R and SHM_W have been modified from their traditional owner-only-read
and owner-only-write values to be owner-and-group-read and owner-and-group-write
on MPE/iX in order to allow increased parent/child flexibility in spite
of MPE's limited POSIX UID/GID support.&nbsp; This functionality change
was submitted back to the 1.3.13-dev source tree at www.apache.org.&nbsp;
The Apache for Unix behavior uses the traditional owner-only values of
SHM_R and SHM_W.</li>
</ul>

<h3>
Minor Apache functionality issues</h3>

<ul>
<li>
Apache for Unix must be run as root to bind to TCP ports 1-1023. Apache
for MPE must call GETPRIVMODE() to bind to TCP ports 1-1023; PM is not
used for ports greater than 1023. The standard web server HTTP port is
80.</li>

<li>
Apache for Unix in standalone mode will detach itself and run in the background
as a system-type process. Apache for MPE in standalone mode cannot detach
itself and run in the background because MPE POSIX doesn't allow this (the
detached child would be killed when the parent terminated).&nbsp; Therefore
you must use an MPE batch job to run Apache in standalone mode.</li>

<li>
Apache for Unix uses process groups to manage child processes. Apache for
MPE cannot use process groups because MPE POSIX doesn't support this. The
implications of this are unknown.</li>

<li>
Apache for Unix uses the setsockopt() option TCP_NODELAY. Apache for MPE
does not, because MPE doesn't support it. But TCP_NODELAY is the default
MPE behavior anyway.</li>

<li>
Apache for Unix uses the setsockopt() option SO_KEEPALIVE.&nbsp; Apache
for MPE does not, because MPE doesn't support it.</li>

<li>
Apache for Unix under inetd reads from the socket via stdin and writes
via stdout. Apache for MPE under inetd reads *AND* writes the socket via
stdin. I consider MPE 5.5 inetd to be broken and poorly documented, so
I submitted SR 5003355016 to address this. If HP ever alters the MPE inetd
to pass the socket the way HPUX inetd does (not likely in the grand scheme
of things), the existing Apache for MPE code will break.</li>

<li>
Apache for Unix will use the @ character in proxy cache filenames, but
since @ is illegal in MPE filenames, Apache for MPE uses the % character
instead.</li>
</ul>

<h2>

<hr WIDTH="100%"></h2>

<h2>
<a NAME="binaries"></a>Binary Distributions</h2>
HP ships a fully supported Apache binary distribution with the Fundamental
Operating System (FOS) in MPE/iX 6.5 and later.&nbsp; This distribution
can be found in the APACHE account.
<p>HP supplies fully supported Apache binary distributions for MPE/iX 6.0
or later available for downloading from <a href="http://jazz.external.hp.com/src/apache/">http://jazz.external.hp.com/src/apache/</a>.
<p>Mark Bixby supplies Apache binary distributions for MPE/iX available
for downloading from <a href="http://www.bixby.org/mark/apacheix.html">http://www.bixby.org/mark/apacheix.html</a>.&nbsp;
Binaries from bixby.org are NOT supported by HP.&nbsp; HP only supports
binaries distributed by HP.
<p>All of the binary distributions mentioned above may possibly include
functionality that hasn't yet been submitted back to the Apache Software
Foundation (though submitting back is the intended goal).&nbsp; Please
read the documentation that comes with these binaries in order to determine
functionality differences (if any) compared to the latest sources available
from the ASF.
<p>If you will be using one of these binary distributions, please stop
reading this document and start reading the specific distribution documentation
for installation details.

Group APACHE</li>
</ul>

<h2>
<a NAME="run"></a>Running Apache</h2>
Simply create and :STREAM the following standalone server job in order
to start Apache:
<pre>!JOB JHTTPD,MGR.APACHE;OUTCLASS=,2
!XEQ SH.HPBIN.SYS "-c 'umask 007; ./HTTPD -f /APACHE/PUB/conf/httpd.conf'"
!eoj</pre>

<h2>
<a NAME="control"></a>Controlling Apache</h2>
Log on as MGR.APACHE (or MANAGER.SYS or any other SM user if you've installed
MPELX36A on 6.0) in order to shutdown or restart Apache via the use of
signals.
<p>To shut down Apache from the POSIX shell:
<pre>$ kill `cat /APACHE/PUB/logs/httpd.pid`</pre>
To shut down Apache from the CI:

> <a NAME="implement"></a>Implementation Considerations</h2>
> While MPE has a very good POSIX implementation that enables fairly
>simple
> porting of Unix applications such as Apache, there are some Unix
>concepts
> which just don't exist or aren't fully implemented in MPE, and so this
> may force some functionality changes in the package being ported.
> <h3>
> Significant MPE vs. Unix OS differences</h3>
>
> <ul>
> <li>
> MPE lacks the concept of a Unix UID=0 root user with special
>privileges.&nbsp;
> Where Unix functions require a user to be executing as root, MPE
>requires
> the user to be executing in priv mode, so the program file must be
>linked
> with PM (Priv Mode) capability, and the Unix function calls must be
>bracketed
> by GETPRIVMODE() and GETUSERMODE() calls.&nbsp; The following Unix
>functions
> used by Apache are affected:</li>
>
> <ul>
> <li>
> bind() for ports less than 1024</li>
>
> <li>
> setgid()</li>
>
> <li>
> setuid()</li>
> </ul>
>
> <li>
> MPE's support for UIDs and GIDs is more limited than Unix.&nbsp; Every
> MPE account maps to a unique GID.&nbsp; Each MPE account can contain
>multiple
> MPE users, and every MPE user maps to a unique UID (UID 0 is not
>supported).&nbsp;
> The current UID for a process must correspond to an MPE user within the
> MPE account that corresponds to the current GID of the process.</li>
>
> <li>
> MPE child processes cannot survive the death of their parent.&nbsp; When
> the parent terminates, any remaining children will be killed.</li>
>
> <li>
> MPE doesn't initialize the envp parameter when invoking the main() of a
> new process.&nbsp; Use the global variable environ instead of envp.</li>
>
> <li>
> MPE link() exists, but always returns EIMPL.&nbsp; Use rename() or
>symlinks
> instead of hard links.</li>
>
> <li>
> MPE doesn't allow the @ character in filenames.</li>
>
> <li>
> MPE lacks support for TCP_NODELAY, but that's the default anyway.</li>
>
> <li>
> MPE lacks support for SO_KEEPALIVE.</li>
>
> <li>
> MPE lacks support for process groups.</li>
>
> <li>
> MPE inetd only passes stdin (and NOT stdout) to the invoked
>service.&nbsp;
> But you can write to stdin just fine.</li>
> </ul>

> <h3>
> Major Apache functionality issues</h3>
>
> <ul>
> <li>
> Beginning with HP-supported Apache 1.3.9 and HP WebWise MPE/iX Secure
>Web
> Server A.01.00 (based on Apache 1.3.9), the User and Group directives in
> httpd.conf are now unconditionally executed as corresponding
>setuid()/setgid()
> calls.&nbsp; Previously this was only done if HTTPD was being run as
>MANAGER.SYS.&nbsp;
> This functionality change was submitted back to the 1.3.13-dev source
>tree
> at www.apache.org.&nbsp; The Apache for Unix behavior is to only honor
> User and Group if running as root.</li>
>
> <li>
> Beginning with HP-supported Apache 1.3.9 and HP WebWise MPE/iX Secure
>Web
> Server A.01.00 (based on Apache 1.3.9), the SVIPC shared memory macros
> SHM_R and SHM_W have been modified from their traditional
>owner-only-read
> and owner-only-write values to be owner-and-group-read and
>owner-and-group-write
> on MPE/iX in order to allow increased parent/child flexibility in spite
> of MPE's limited POSIX UID/GID support.&nbsp; This functionality change
> was submitted back to the 1.3.13-dev source tree at
>www.apache.org.&nbsp;
> The Apache for Unix behavior uses the traditional owner-only values of
> SHM_R and SHM_W.</li>
> </ul>
>
> <h3>
> Minor Apache functionality issues</h3>
>
> <ul>
> <li>
> Apache for Unix must be run as root to bind to TCP ports 1-1023. Apache
> for MPE must call GETPRIVMODE() to bind to TCP ports 1-1023; PM is not
> used for ports greater than 1023. The standard web server HTTP port is
> 80.</li>
>
> <li>
> Apache for Unix in standalone mode will detach itself and run in the
>background
> as a system-type process. Apache for MPE in standalone mode cannot
>detach
> itself and run in the background because MPE POSIX doesn't allow this
>(the
> detached child would be killed when the parent terminated).&nbsp;
>Therefore
> you must use an MPE batch job to run Apache in standalone mode.</li>
>
> <li>
> Apache for Unix uses process groups to manage child processes. Apache
>for
> MPE cannot use process groups because MPE POSIX doesn't support this.
>The
> implications of this are unknown.</li>
>
> <li>
> Apache for Unix uses the setsockopt() option TCP_NODELAY. Apache for MPE
> does not, because MPE doesn't support it. But TCP_NODELAY is the default
> MPE behavior anyway.</li>
>
> <li>
> Apache for Unix uses the setsockopt() option SO_KEEPALIVE.&nbsp; Apache
> for MPE does not, because MPE doesn't support it.</li>
>
> <li>
> Apache for Unix under inetd reads from the socket via stdin and writes
> via stdout. Apache for MPE under inetd reads *AND* writes the socket via
> stdin. I consider MPE 5.5 inetd to be broken and poorly documented, so
> I submitted SR 5003355016 to address this. If HP ever alters the MPE
>inetd
> to pass the socket the way HPUX inetd does (not likely in the grand
>scheme
> of things), the existing Apache for MPE code will break.</li>
>
> <li>
> Apache for Unix will use the @ character in proxy cache filenames, but
> since @ is illegal in MPE filenames, Apache for MPE uses the % character
> instead.</li>
