Perl/iX for HP 3000 MPE
http://www.cccd.edu/~markb/perlix.html
Perl language for MPE
Last updated July 15, 1998 @ 2030 UTC
------------------------------------------------------------------------
What's New
* July 15, 1998
o Changed startperl to #!/PERL/PUB/perl so that Perl will recognize
scripts more easily and efficiently.
* July 8, 1998
o Updated to version 5.004_70 (internal developer release) which is
now MPE-ready. The next public freeware release of Perl should
compile "straight out of the box" on MPE. Note that this version
of Perl/iX was strictly internal to me and never publicly
released. Note that BIND/iX is now required (well, the include
files and libbind.a) if you wish to compile Perl/iX.
* November 6, 1997
o Updated to version 5.004_04. No changes in MPE-specific
functionality.
------------------------------------------------------------------------
Welcome
This is the official home page for the HP 3000 MPE port of the Perl
scripting language which gives you all of the power of C, awk, sed, and sh
in a single language. Check here for the latest news, implemented
functionality, known bugs, to-do list, etc. Status reports about major
milestones will also be posted to the HP3000-L mailing list and its
associated gatewayed newsgroup comp.sys.hp.mpe.
I'm doing this port because I can't live without Perl on the HPUX machines
that I administer for the Coast Community College District, and I want to
have the same power available to me on MPE.
Please send your comments, questions, and bug reports directly to me, Mark
Bixby, by e-mailing to markb@cccd.edu. Or just post them to HP3000-L. You
can also telephone me at +1 714 438-4647 Monday-Friday 0815-1745 PDT
(1615-0145 UTC).
The platform I'm using to do this port is an HP 3000 969KS200 running
MPE/iX 5.5 and using the gcc 2.8 compiler from
http://www.interex.org/sources/freeware.html.
The combined porting wisdom from all of my ports can be found in my MPE/iX
Porting Guide.
------------------------------------------------------------------------
System Requirements
* MPE/iX 5.5 or later. This version of Perl/iX does NOT run on MPE/iX
5.0 or earlier, nor does it run on "classic" MPE/V machines.
* The Perl binary requires that you must have converted your NMRL
libraries in /lib/lib*.a and /usr/lib/lib*.a to NMXL libraries
/lib/lib*.sl and /usr/lib/lib*.sl via the LIBSHP3K script that comes
with the GNUCORE portion of the FREEWARE tape.
* If you wish to recompile Perl, you must install both GNUCORE and
GNUGCC from the FREEWARE tape.
* Perl/iX will be happier if you install the MPEKX76A additional POSIX
filename characters patch, but this is optional.
* If you will be compiling Perl/iX yourself, you will also need the
/BIND/PUB/include and /BIND/PUB/lib portions of BIND/iX.
------------------------------------------------------------------------
Demos
Here is a brief selection of some sample Perl/iX uses:
* A web feedback CGI form that lets a web browser user enter some data
and send e-mail to the person responsible for reading the feedback
comments. The CGI is written in Perl and requires Sendmail/iX.
------------------------------------------------------------------------
How to Obtain Perl/iX
1. Download Perl using either FTP.ARPA.SYS or some other client
2. Extract the installation script
3. Edit the installation script
4. Run the installation script
Download Perl using FTP.ARPA.SYS from your HP 3000 (the preferred
method).....
:HELLO MANAGER.SYS
:XEQ FTP.ARPA.SYS
open ftp.cccd.edu
anonymous
your@email.address
bytestream
cd /pub/mpe
get perl5.005.tar.Z /tmp/perl.tar.Z
exit
.....Or download using some other generic web or ftp client (the alternate
method)
Download the following files (make sure that you use "binary mode" or
whatever client feature that is 8-bit clean):
* Perl from http://www.cccd.edu/ftp/pub/mpe/perl5.005.tar.Z or
ftp://ftp.cccd.edu/pub/mpe/perl5.005.tar.Z
Upload those files to your HP 3000 in an 8-bit clean bytestream manner to:
* /tmp/perl.tar.Z
Then extract the installation script (after both download methods)
:CHDIR /tmp
:XEQ TAR.HPBIN.SYS 'xvfopz /tmp/perl.tar.Z INSTALL'
Edit the installation script
Examine the accounting structure creation commands and modify if necessary
(adding additional capabilities, choosing a non-system volume set, etc).
:XEQ VI.HPBIN.SYS /tmp/INSTALL
Run the installation script
The accounting structure will be created and then all files will be
extracted from the archive.
:XEQ SH.HPBIN.SYS /tmp/INSTALL

Distribution Contents Highlights
README
The file you're reading now.
INSTALL
Perl/iX Installation script.
PERL
Perl NMPRG executable. A version-numbered backup copy also exists.
You might wish to "ln -s /PERL/PUB/PERL /usr/local/bin/perl".
lib/
Perl libraries, both core and add-on.
man/
Perl man page documentation.
public_html/feedback.cgi
Sample feedback CGI form written in Perl.
src/perl5.005
Source code.
------------------------------------------------------------------------
How to Compile Perl/iX
1. cd src/perl5.005
2. Read the INSTALL file for the official instructions
3. ./Configure
4. make
5. ./mpeix/relink
6. make test (expect 31 out of 5899 subtests to fail, mostly due to MPE
not supporting hard links and handling exit() return codes improperly)
7. make install
8. Optionally create symbolic links that point to the Perl executable,
i.e. ln -s /usr/local/bin/perl /PERL/PUB/PERL
The summary test results from "cd t; ./perl -I../lib harness":
Failed Test Status Wstat Total Fail Failed List of failed
-------------------------------------------------------------------------------
io/fs.t 26 8 30.77% 2-5, 7-9, 11
io/pipe.t 12 2 16.67% 11-12
lib/posix.t 18 1 5.56% 12
op/die_exit.t 16 16 100.00% 1-16
op/exec.t 8 2 25.00% 5-6
op/stat.t 58 2 3.45% 3, 35
Failed 6/183 test scripts, 96.72% okay. 31/5899 subtests failed, 99.47% okay.
------------------------------------------------------------------------
Getting Started with Perl/iX
Create your Perl script files with "#!/PERL/PUB/perl" (or an equivalent
symbolic link) as the first line. Use the chmod command to make sure that
your script has execute permission. Run your script!
If you want to use Perl to write web server CGI scripts, obtain and install
CGI.pm. Build CGI.pm and all other add-on modules below /PERL/PUB/src/.
Be sure to take a look at the CPAN module list. A wide variety of free Perl
software is available.
------------------------------------------------------------------------
MPE/iX Implementation Considerations
There some minor functionality issues to be aware of when comparing Perl
for Unix (Perl/UX) to Perl/iX:
* MPE gcc/ld doesn't properly support linking NMPRG executables against
NMXL dynamic libraries, so you must manually run mpeix/relink after
each re-build of Perl.
* Perl/iX File::Copy will use MPE's /bin/cp command to copy files by
name in order to preserve file attributes like file code.
* MPE (and thus Perl/iX) lacks support for setgrent(), endgrent(),
setpwent(), endpwent().
* MPE (and thus Perl/iX) lacks support for hard links.
* MPE requires GETPRIVMODE() in order to bind() to ports less than
1024. Perl/iX will call GETPRIVMODE() automatically on your behalf if
you attempt to bind() to these low-numbered ports. Note that the
Perl/iX executable and the PERL account do not normally have CAP=PM,
so if you will be bind()-ing to these privileged ports, you will
manually need to add PM capability as appropriate.
* MPE requires that you bind() to an IP address of zero. Perl/iX
automatically replaces the IP address that you pass to bind() with a
zero.
* If you use Perl/iX fcntl() against a socket it will fail, because MPE
requires that you use sfcntl() instead. Perl/iX does not presently
support sfcntl().
* MPE requires GETPRIVMODE() in order to setuid(). There are too many
calls to setuid() within Perl/iX, so I have not attempted an automatic
GETPRIVMODE() solution similar to bind().
------------------------------------------------------------------------
Known Bugs Under Investigation
* None
------------------------------------------------------------------------
To-Do List
* Make setuid()/setgid() support work.
* Make sure that fcntl() against a socket descriptor is redirected to
sfcntl().
* Add support for Berkeley DB once I've finished porting Berkeley DB.
* Write an MPE XS extension library containing miscellaneous important
MPE functions like GETPRIVMODE(), GETUSERMODE(), and sfcntl().
------------------------------------------------------------------------
Change History
* October 16, 1997
o Added Demos section to the Perl/iX home page so you can see some
sample Perl applications running on my 3000.
* October 3, 1997
o Added System Requirements section to the Perl/iX home page just
so the prerequisites stand out more. Various other home page
tweaks.
* October 2, 1997
o Initial public release.
* September 1997
o Porting begins.
