VSI-I64VMS-PYTHWHLS-A0000-3-1-RNOTES.PDF

This document describes the Python Packages Kit for VSI OpenVMS I64, a collection of commonly used Python packages for web application development, integration, and testing on VSI OpenVMS systems. While packages can be installed directly from PyPI, this kit offers a more convenient or straightforward installation in certain situations.

Key points include:

• Latest Update: The cryptography package has been updated to use OpenSSL 1.1.1gb for VSI OpenVMS.

• Requirements:

  • VSI OpenVMS Version 8.4-1H1 I64 or higher.
  • Installation on an ODS-5 enabled disk (critical for success).
  • Python 3.8.2 for VSI OpenVMS I64 or higher.

• Installation of the Kit:

  • The kit, based on Python wheels, is installed by a privileged user using the command: $ PRODUCT INSTALL PYTHWHLS.

• Post-Installation & Installing Individual Packages:

  • After installation, lines must be added to SYSTARTUP_VMS.COM to define logical names PYTHON_WHEELS$ROOT and PIP_FIND_LINKS, which help the PIP installer locate packages within the kit.
  • Individual packages are then installed using: $ python -m pip install --no-index <module-name>. The --no-index option (or defining PIP_NO_INDEX 1) prevents PIP from attempting internet downloads.
  • Users should also ensure the logical name PYTHONCASEOK is not defined.

• Temporary Disk Space: Installation may require considerable temporary disk space, defaulting to SYS$SCRATCH, but configurable via TMPDIR or PIP_CACHE_DIR (using UNIX syntax).

• Included Packages: The document provides a comprehensive list of all Python packages and their versions included in this release, noting that dependencies are also bundled.
