Completely disagree. Adding something to PATH is nearly unacceptable clutter even during installation, and completely unacceptable (to me) after uninstallation. If you install Python several times, will the path get longer and longer? In principal, uninstallation should completely undo installation. There should be only plausible exceptions, e.g. when the user still has files in a directory, deleting the directory is unacceptable as it would also delete the files. The big problem where the Python installer (and MSI in general) fails is uninstallation of file associations, which doesn't restore the file assocations to what they were (of course, that software might be gone) > 2.

I don't think this can be done for 2.6, so there is no need for synchrony - there is plenty of time to come up with a solution for 2.7/3.1. In any case, I'll be away for the next three weeks. > It cannot[1] remove them at uninstallation. > ^ [1].

You cannot uninstall the path through unsetting the PATH variable, sure. So perhaps using the Environment table is the wrong approach in the first place. You can do nearly anything in a custom action, so it should be possible to remove the path entry on uninstallation by means of a custom action. If such a solution was designed, there would still be many questions, such as: - what is the actual problem being solved? Is it real? Could there be other solutions to that problem (such as installing things into system32, or somewhere else that is on the PATH already)? - if the path is modified, should the Python directory be added to the beginning or the end? - IMO, this feature needs to be customizable, and IMO, it must be turned off by default. So how should such customization be offered? These questions can partially be discussed in the tracker item proposing the patch. The very end-user related aspects of it need to be discussed on python-dev (perhaps taking a poll whether this is desirable, whether it should be optional, and if so, what the default should be) _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue3561> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
