Summary: make altinstall installs pydoc

Initial Comment:

I did the "make altinstall" rather than the "make
install" as suggested on

  http://www.python.org/download/releases/2.5/

This worked great, creating a 

  /usr/local/bin/python2.5

which doesn't clash with my /usr/bin/python. However,
it also created a

  /usr/local/bin/pydoc

which did clash with my /usr/bin/pydoc. I just removed
it and all is well. Should altinstall not create pydoc?
It could create pydoc2.5 rather than pydoc, but then
the shebang line would have to be changed to python2.5.
What about smtpd.py, idle, and python-config, which
were also created by altinstall? They don't currently
conflict with anything I have for Python 2.4, but the
potential is there for the same problem.

Ah, it's a bit worse than that.  Your /usr/loca/bin/pydoc
would not have worked anyway.  It's first line:

#!/usr/local/bin/python

would give an error because only /usr/local/bin/python2.5
exists.

Sorry, I haven't had a chance to look at this again. I just
installed Python-2.5b1 and it's still the same way. Here's
what I did to fix things up after the make altinstall...

  # cd /usr/local/bin
  # for file in pydoc idle smtpd.py python-config; do
  mv $file ${file}2.5
  sed -i 's@/usr/local/bin/python@/usr/local/bin/python2.5@'
${file}2.5
  done

Now, how to fix up the Makefile.pre and setup.py so this
isn't necessary...

I'm not sure I know how. It looks like the downloaded files
have the following shebang lines

  Tools/scripts/pydoc   => #!/usr/bin/env python
  Tools/scripts/idle    => #! /usr/bin/env python
  Lib/smtpd.py          => #! /usr/bin/env python
  Misc/python-config.in => #!@BINDIR@/python

whereas the installed files have

  /usr/local/bin/pydoc         => #!/usr/local/bin/python
  /usr/local/bin/idle          => #!/usr/local/bin/python
  /usr/local/bin/smtpd.py      => #!/usr/local/bin/python
  /usr/local/bin/python-config => #!/usr/local/bin/python

so they're already getting rewritten somewhere. We want both
their names and their shebang lines to have the version

  /usr/local/bin/pydoc2.5          => #!/usr/local/bin/python2.5
  /usr/local/bin/idle2.5           => #!/usr/local/bin/python2.5
  /usr/local/bin/smtpd.py2.5       => #!/usr/local/bin/python2.5
  /usr/local/bin/python-config2.5  => #!/usr/local/bin/python2.5

It seems that python-config appears in the Makefile, so
adding something like

	sed -e "s, at BINDIR@,$(BINDIR)," <
$(srcdir)/Misc/python-config.in >python-config$(VERSION)$(EXE)
	$(INSTALL_SCRIPT) python-config
$(BINDIR)/python-config$(VERSION)$(EXE)
	rm python-config

to Makefile.pre.in in an altlibainstall section or something
might be all we need for that.

The others are named in setup.py

          # Scripts to install
          scripts = ['Tools/scripts/pydoc',
'Tools/scripts/idle',
                     'Lib/smtpd.py']

but I haven't worked out where they get rewritten or
installed yet.

You are right: altinstall shouldn't overwrite these
conflicting files. For idle and pydoc, I would think that
altinstall should install version-specific copies - users
actually might want to run an idle or pydoc associated with
a specific version, likewise for python-config. I'm
uncertain why smtpd.py is installed at all.

Would you be willing to work on a patch? You are right that
the shebang line should get updated during the installation,
too.
