I don't know of any official perl but we have perl on our VMS system.
Not sure how it got there....

The Python RTE has received a significant update - WSGI.

In a nut-shell, WSGI attempts to standardise the API for, and interactions
with a Web-server, of a Web application written using Python - the Python
Web Server Gateway Interface v1.0, as described in PEP 333

http://www.python.org/dev/peps/pep-0333/

The WSGI code has been developed under the sponsorship of SysGroup

http://www.sysgroup.fr/

and generously been made available to the wider WASD community.

The kit may be found on the WASD download page

http://wasd.vsm.com.au/wasd/

and the new PyRTE source directory at

http://wasd.vsm.com.au/ht_root/src/python/

Jean-François Piéronne will follow-up this email with news of Python on
VMS, further Python/Web applications, and developments based on the WSGI
model.

Regards, Mark.

I uses the two LD-disks. Just to download and mount as LDA
drives. They are pre-installed and rady to run. Works
like a charm, inkl the Rdb interface and a lot of VMS
specific system functions.

It's always flattering to find yourself quoted :-) but this one would be
better in context. Jean-François Piéronne is the energetic 'team' that
provided and maintains the port of Python for VMS (amongst other
things). His Python-for-VMS site is

http://vmspython.dyndns.org/

a Python based wiki made available via a WASD

http://wasd.vsm.com.au/

enabled Web site running on VMS. WASD has an efficient, persistent
environment for hosting Python web applications. What Tom has posted
here is an announcement made on the info-WASD mailing list about recent
enhancements to that environment. Not purely about VMS Python :-)

I've never had any problems with the Python on VMS that I grabbed
a few months ago.

Is there a mod_python for CSWS (Apache) readily available? I'm
interested in trying out the Python stuff JFP has done, but I'm using
Apache. I'd rather find a mod_python than learn a new web server.

Thanks for the feedback everyone.

It makes me more comfortable installing it on a production system knowing
that others are using it ok.

I remember that years ago, someone has tried to build mod_python.
But Python set numbers of crtl features and some of these features break
CSWS. After this I have add the ability to control these features
settings using some specific Python logical names, but doing this will
probably break some python tools (for example I suspect that Mercurial
or Django won't work correctly). May be latest version of CSWS doesn't
have this problem, I don't know.
You can try to build mod_python or better mod_wsgi, I expect that it
will be not very difficult.
Or you can use the Python embedded web server using mod_proxy. But a
WASD solution has many advantages.
I know sites which run, successfully, WASD/Python on production system
for years.

But if you're committed to Apache and just want to run Python scripts,
you can wrap them in .COM files and put them in CGI-BIN, or you can access
them via MOD_OSU and copy the code in the DECnet object which invokes perl
for perl scripts and invoke python for .py scripts.

That obviously won't give you the highest possible performance - in general,
WASD is the way to go for highest performance as a VMS webserver - but it
cleanly separates the Python and Apache execution environments, lets you set
whatever CRTL things you need for Python, and lets you test your Python
programs from the command line, which is handy.

That correct, another option is to use mod_fastcgi, if it is available
on VMS, this will, probably, work with all Python application supporting
wsgi.

This could only be for experimental or casual purposes for at least a
couple of reasons. 1) The VMS Apache CGI implementation is notoriously
latent and resource intensive as to make it unusable for anything but
casual access (using mod_osu would probably circumvent this, I haven't
experimented). 2) The Python engine itself is expensive to instantiate
(again latency and resources).

Web server skirmishes aside; most interpreted web environments intended
for non-trivial usage require a persistent engine. Hence much of the
rationale for the mod_perl, mod_php, mod_wsgi, etc., of this world.
More so for VMS. Most non-trivial web applications are themselves
expensive and latent to load and initialise. For (at least) these
reasons the Python developers and Python web application designers
appear to go to some trouble to make an application equally capable of
persistence.
