[Python-Dev] Second draft: PEP397: Python launcher for Windows

[Mark Hammond]

Hi all,
   I've made some changes to the draft PEP and checked it into the PEP 
repository as PEP397.  The reference implementation is currently being 
tracked at http://bugs.python.org/issue11629.

Most of the changes should not be too controversial, but of note:

* I've added lots of discussion about the child-process issue and the 
wording now states, basically, that in-process is not feasible, but if 
we use the win32 Job API we can arrange for the child to be killed with 
the parent on Windows XP and later.  The reference implementation 
demonstrates this thanks to an example from Curt Hagenlocher.

* 64bit and 32bit considerations have been added, along with basic 
information about other distros and implementations.

* The somewhat controversial optional first command-line parameter which 
allows you to specify a particular version for interactive use has grown 
an almost-certain-to-be-controversial option to specify the bittedness 
of the Python you wish to start.  I've added this mainly as it would 
scratch my personal itch as I tend to have 32bit and 64bit 
implementations of most versions available and while this isn't 
particularly common, I'm going to attempt to defend it on the principle 
of "just don't use it if you don't like it" :)  Note the reference 
implementation does not yet implement this, nor does it implement the 
general policy about 32bit vs 64bit considerations.

Please let me know what you think and what objections/comments/etc remain.

Thanks,

Mark
