Hi.

Can't reach http://www.vmspython.org/ at the moment.
Does anyone know what's up here? It would be sad if
that port would not be available any more. And VSI
only has IA64 versions of Python...

Jan-Erik.

Replying to myself, and for anyone interested...

JFP has shut down his site with his Python port for Alpha (and IA64).
When asked, he sent me an explanation for this that I can understand.
I have also sent a question to VSI asking what their view is on
Python for Alpha.

And as I said, just if anyone is interested in Python on Alpha...

Jan-Erik.

We can make a guess: after spending 15 years or more maintaining this
for the mostly ungrateful users he has changed his priorities.

I believe the source code is available so anyone that want should be
able to build from source.

An open-source project does not measure its success by the number of passive users, but by the level of active contributions from the community.

Too often I see this attitude from people looking on open-source software as being no different from proprietary products from big companies. The most common symptom of this is when they complain about claimed deficiencies in the product, without stepping forward to offer fixes. Or sponsoring someone who can make those fixes.

The reply from JFP was not pointing against the users.

What source? The sources for the JFP port and all the components?

Yes.

I do not recall any details but I believe the source was
available.

OK, right, on that site. I get an SEC_ERROR_EXPIRED_CERTIFICATE.
And for some reason not the usual button to bypass that error.

I looked some years ago to setup the build environment for Alpha,
but it was not an easy task...

I could get in with FF.

True.

Lot of code.

Lot of disk space to build.

Lot CPU time and wall time to build.

Disk space is cheap.

Device Device Error Volume Free Trans Mnt
Name Status Count Label Space Count Cnt
ITANIC$DKB0: Mounted 0 I64SYS 133.46GB 255 1
ITANIC$DKB1: Mounted 0 DISK1 132.78GB 1 1
ITANIC$DKB2: Mounted 0 DISK2 136.69GB 1 1
ITANIC$DKB3: Online 0

Need more than that?

But, I'm assuming C, and I don't do C.

Perhaps I could make the resources available ???

I don't know.

I know that the output of the build is over 150 MB.

(note that Jan-Erik is looking for Alpha not Itanium - VSI offer
Python for Itanium)

If someone is willing to do the work and just need the system then
that would be great.

Any of the VMS Port people interested?

I know you already have a lot of stuff to maintain, but I also believe
that you have appropriate build setups.

The DECUServe system (eisner.decus.org) would be a fine place for
that work to be done.

They even have a beta of 3.10, which impresses me. But, looking at the compatibility issues <https://wiki.vmssoftware.com/VMS_Python_compatibility_issues>:

The functions select() and poll() work only with sockets

Kind of like Microsoft Windows ...

We have already added support for pipes, mailboxes, etc. to the CRTL's poll. This was done when porting Postgres. But it will probably help Python after installing a new version of the CRTL.

Note that it is not a Python issue but a CRTL/VMS issue.

It’s an OS issue on Windows, too.
