According to PEP-11, we have to remove VMS support. |

FWIW, I have another Itanium box that I've earmarked for OpenVMS. I don't believe the installation media is readily available for free, though, so I'd need to ping HP to try arrange a copy. |

I'm in contact with Sysgroup, a french company which ported Python 2 on VMS. |

If they ported Python 2 on VMS, even though Python 2 is already supposed to work on Python 2, it means our compatibility code is broken. |

Hi , I love VMS very much, I could not concentrate actively on python because other work commitments ate up most of my time. I have left my job at HP and am now a PhD student and university of Nevada , Reno . Now that I do not have any professional commitments , I should be able to work on it in a more timely manner. I had used python for an internal project in HP. The problem now I have is that I need access to a VMS machine. I was not able to setup a build bot because buildbot needed some ports to be open , the machine provided HP did not give privilleges to do that. Another thing was that they wanted me to use gnv to compile python in VMS . I however did not really agree with it , gnv is buggy and you need to enable millions to of hacks to gets programs to compile. Programs written for VMS should be written the VMS way not the unix way. I was able to get Python 3.x to compile using gnv finally but it would not run properly. Is it possible for anyone to provide a VMS box with C Compiler and tools ( MMS) so that I can start working on it again. I will try asking HP , whether they would allow me to start working on it on the old VMS cluster they provided. --Thomas |

We don't have any box that is capable of running VMS. Even Trent's Snakebit setup doesn't have VMS although he has lots of exotic hardware and OS, even HP-UX on a PA-RISC machine. It seems to be possible to run VMS on a cluster of RaspberryPi machines [1]. The PSF might help out if you need some official contacts to acquire licenses.

It's a quad Itanium2 with ~24-32GB of RAM (same hardware as the 'titanium' HP-UX box). I just haven't set it up yet due to lack of interest. First thing I'll need is OpenVMS media/licenses. I'll ping HP and see if they can assist. |

I have asked HP for access to a VMS box so that I restart my work. I initially checked with the university to see if I can get hold of an Itanium box. @Trent : If you have HP - UX already running, you may make use of Hyper-V to get vms running without changing the existing the HP-UX installation. |

Ah, I forgot about the VOE stuff. That will work a lot better. I'll still need to acquire VMS media though. You're not a committer are you? I can sort you out with access to Snakebite anyway -- email me your ssh key if you're interested (trent at snakebite.org). I'd recommend dropping by #python-dev on irc.freenode.net too. |

Unless somebody says otherwise I'm going to remove VMS-related code over the course of the next couple of days. PEP 11 says: Name: VMS (issue 16136) Unsupported in: Python 3.3 Code removed in: Python 3.4 |

Access to VMS licenses and media: 1. Hobby - non-commercial applications - Free with 1 year time-bombed license keys with free media download. A self-service mostly web based system. http://www.openvms.org/pages.php?page=Hobbyist Easiest way to get a membership ID is to join Encompasserve.org which is free. Unfortunately right now, HP is in their holiday shutdown and Encompasserve.org is being relocated from Wisconsin to Massachusetts. Both should be back available sometime in the beginning of January 2014. 2. Commercial - Company Alliance One Membership. It is my understanding that upon acceptance to the program, 1 year time-bombed license keys are available with free. Search for "Alliance One" on the HP site. This has been the case for well over 10 years, so VMS programmers for open source projects should normally have no problem getting current media or license keys. There are several free Alpha emulators now available for download. These are less functional versions of the commercial versions of the emulator. While there are also commercial VAX emulators that may be available, SimH VAX is free and open source. Resources: comp.os.vms newsgroup, www.openvmshobbyist.com, sourceforge GNV and vms-ports projects, encompasserve.org, and www.openvms.org GNV: GNV as packaged by HP has multiple problems. To use it at a minimum you need to install the newer Bash and Coreutils kits from the GNV sourceforge project. Read http://sourceforge.net/p/gnv/wiki/InstallingGNVPackages/ before installing the updates. Running configure scripts on GNV typically requires some hacks because most configure scripts test with out the header files, and on VMS, the header files are needed to get ANSI/ISO or X/Open behavior or bug-fixes. Otherwise the tests fail. Instructions: http://sourceforge.net/p/vms-ports/wiki/GeneratingConfigh/ As far as removing the VMS specific code, it is very likely that much of the VMS specific code is not needed for the current 8.3/8.4 versions of VMS, so it is probably better for a someone porting Python 3.x to VMS to start with clean code. If a VMS library routine is missing or does not behave properly, it is better handled with a replacement routine than by putting #ifdef in the code. |

The platform.py module is intended to be usable by several Python versions, so I think it's better to keep the code around for a little longer. |

Encompasserve.org is now back up. It took a little longer than expected. Should be no issues now in getting free hobby license keys for VMS on VAX, Alpha, and Itanium by using the web forms. |

Does not look like anything vital to VMS got removed. Configure basically worked under current GNV. And a few tweaks later with out changing any files checked out of the Mercurial repository, make is producing a functional python binary before it quits. bash-4.2$ ./python notdeadyet.py I'm not Dead Yet, I think I'll go for a Walk bash-4.2$ ./python Python 3.5.0a0 (default, Jun 17 2014, 00:03:16) [C] on openvms0 Type "help", "copyright", "credits" or "license" for more information. >>> Exit bash-4.2$ uname -a OpenVMS EAGLE 0 V8.4 AlphaServer_DS10_617_MHz Alpha Alpha HP/OpenVMS More work is needed of course, mostly adding some more libraries that Python is expecting and showing GNV how to have configure and make find them. A lot of compile warnings need to be resolved. |

It does build with some tweaking here and there. But I ran into runtime issues. I am sorry, I cannot dedicate time on it further. IMHO anything built for VMS should use VMS specific API's in the way they are designed for stability and performance reasons, some more code needs to be written.

Most of the issues needed to build python3 properly on VMS involve either bugs in the VMS C API that need to be worked around or missing libraries that Python3 expects to have. As none of the Python developers should need to care about this, and these issues are common to ports of other VMS projects, I plan to do the following unless someone objects: 1. Create a new issue tracker here to document what it takes to attempt build the in development branch of Python on VMS, and try keep it up to date with significant issues found. 2. Create a mercurial repository on the vms-ports sourceforge site that contains the additional VMS specific files that are needed to build the in development branch. I will also create a VMS specific discussion there about the more detailed status of the port progress. 3. Where cases are actually found where the issue is in python, such as posixmodule.c overriding the configure files to assume fork is present when configure detected it was not, a ticket here will be filed. If someone then shows up inquiring at the status of VMS, then they can be pointed at that new ticket. |
