December 2015 subprocess.py This is a revised implementation of the Python subprocess module which supports OpenVMS as well as Windows and Posix compliant Unix/Linux environments. This module replaces the "standard" subprocess.py module. The module was developed and has been tested with the WAF based build environment of Samba 4.3.1 on OpenVMS running under GNV. In comparison to a prior OpenVMS implementation of subprocess this version does not require editing of script files to adjust quoting. The implementation uses a shell script to submit commands to bash and or sh. These are temporary files and are automatically deleted after their use. The comments in the file explain more. This implementation relies upon some C helper files. These are built into a shared image which is then referenced and used by the subprocess.py module. The C code implements the necessary code to properly vfork()/execv*() from Python on OpenVMS as well as to support a select() function and other buffer checking code to provide for non-blocking IO. To install, unzip the kit, set your default to this directory containing the contents of the zip file and execute these commands: $COPY SUBPROCESS.PY PYTHON_ROOT:[LIB] @BUILD This will build the shareable image to support the Python SUBPROCESS module on OpenVMS and copy the resultant executable to PYTHON_ROOT:[VMS.LIB] The contents of the zip file are: Archive: subprocess.zip Length Date Time Name --------- ---------- ----- ---- 374 12-23-2015 17:56 subprocess/build.com 2126 12-24-2015 13:07 subprocess/readme.txt 96648 12-23-2015 17:52 subprocess/subprocess.py 29718 12-21-2015 07:24 subprocess/vms_poll_select_hack.c 3286 11-28-2015 12:44 subprocess/vms_vfork.c 198 11-28-2015 15:32 subprocess/VMS_VFORK_XFR.OPT --------- ------- 132350 6 files This code is provided AS IS.
