[Octave-bug-tracker] [bug #60472] pkg -global option changes pkg prefix for subsequent calls

[Nicholas Jankowski]

Follow-up Comment #3, bug #60472 (project octave):

stepping through uninstall.m to where it crashes, it gets to the line 107
block to delete the directories.

the results of 'desc = installed-pkgs_lst(i)' for the single ga package is:


debug> desc
desc =

  scalar structure containing the fields:

    name = ga
    version = 0.10.2
    date = 2020-12-02
    author = Luca Favatella <slackydeb@gmail.com>
    maintainer = Octave-Forge community <maintainers@octave.org>
    title = Genetic Algorithm
    description = Genetic optimization code
    categories = Optimization
    depends =
    {
      [1,1] =

        scalar structure containing the fields:

          package = octave
          operator = >=
          version = 3.4.0

    }

    autoload = yes
    license = GPL version 3 or later
    url = http://octave.sf.net
    dir =
C:\Programs\Octave\octave-dev\mingw64\share\octave\packages\ga-0.10.2
    archprefix =
    loaded = 0


it steps through the line 125 rmdir(desc.dir, "s") without problem. same with
the line 129 rmdir(getarchdir(desc),"s").  for reference:


debug> getarchdir(desc)
ans = x86_64-w64-mingw32-api-v55


then it gets to 

        if (dirempty (desc.archprefix))
          rmdir (desc.archprefix, "s");
        endif


the if statement is true,  so it runs the rmdir line, and rmdir apparently
crashes to desktop when passed an empty string.

so... is this related to the prefix thing? should rmdir not be crashing when
passed an empty string? is it an odd combination of the two?
