Upgrading from 2.5 to 2.6

[Daniel Klein]

Are there any guidelines for upgrading from 2.5 to 2.6?

Do you have to uninstall 2.5, or does the installer do that for you?

I have wxPython, mod_python and Django installed. Will these have to
reinstalled/reconfigured for 2.6?

Platform: Windows XP Pro SP3

Dear Daniel,

Python 2.5 and 2.6 can coexist, so there isn't any need for some
kind of upgrade procedure. Installing 2.6 will not affect your
2.5 installation.

Do you have to uninstall 2.5, or does the installer do that for you?

No. After installing 2.6, 2.5 will still be around, with all its
add-ons. If you want 2.5 to disappear, you should uninstall
it first.

I have wxPython, mod_python and Django installed. Will these have to
reinstalled/reconfigured for 2.6?

Yes, that will be necessary.

Regards,
Martin

A reason you might want to keep version 2.5 is that
even systems that supposedly work in 2.6 sometimes
don't because they never actually tested it with
2.6. That's rare, but it does happen, so you might
want 2.5 around until you verify that everything
works in 2.6 like it's supposed to.

Do you have to uninstall 2.5, or does the installer do that for you?

Neither. It will be installed in a separate directory. If you don't want
2.5 any more, you can uninstall it yourself from Control Panel.

I have wxPython, mod_python and Django installed. Will these have to
reinstalled/reconfigured for 2.6?

Yes. Each major version (2.4, 2.5, 2.6) is separate, and has its own DLL.
Further, assuming you installed these using MSIs or Windows exes, you will
have to download new versions of them.

That isn't entirely true. In Windows, python files bound to a
particular version of python in the registry. So, for example, if you
double click on "some_prog.py" to run it, then it will by default
start up using python2.6 once it is installed. Also right-clicking on
a file and selecting "edit with Idle" will open the version of Idle
associated with 2.6 (under 2.6). This is a minor difference, but I
wouldn't say that there are no side effects. They can be easily worked
around.

Indeed. Notice that, at installation time, you have the option to chose
whether the new version should associate itself with the .py extension
or not. Through APR (add-remove-programs), you can later change that
also - unselect it in one installation, then select it in the other
(or run the repair installation if you selected it twice).

I'd say the wording in the installer is unfortunate. The option is labeled
"Register extensions" and for some time I thought it was related to
..pyd/.dll files ("C extensions"), not "Associate .py files to this Python
installation"

Unfortunately, I think this is too long for the available space.

How about "Make default Python"?
