Public bug reported: The Ruby script addon-manager.rb contains an error in the code for the remove command. This bug causes certain addons where the ~/.vim directory is actually a symbolic link to another directory. This is the case for the Vim R plugin, distributed as a Debian package here:
http://sites.google.com/site/jalvesaq/vimrplugin Removal will fail because it attempts to invoke a rmdir on the symbolically-linked ~/.vim file, which causes a Ruby exception. Steps to reproduce the behavior: 1) Install vim-addon-manager 2) Install the Vim R plugin DEB package from http://sites.google.com/site/jalvesaq/vimrplugin 3) Move the ~/.vim folder to another location, such as ~/vimbak 4) Create a temporary folder ~/tmpvim 5) Create a symbolic link with "ln -s ~/tmpvim ~/.vim" 6) Run "vim-addons install r-plugin" 7) Run "vim-addons remove r-plugin" 8) Observe an error message like the following Info: removing installed addon 'r-plugin' from /home/chris/.vim /usr/lib/ruby/1.8/fileutils.rb:264:in `rmdir': Not a directory - /home/chris/.vim (Errno::ENOTDIR) from /usr/lib/ruby/1.8/fileutils.rb:264:in `rmdir' from /usr/lib/ruby/1.8/fileutils.rb:263:in `each' from /usr/lib/ruby/1.8/fileutils.rb:263:in `rmdir' from /usr/lib/ruby/1.8/vim/addon-manager.rb:68:in `remove' from /usr/lib/ruby/1.8/set.rb:194:in `each' from /usr/lib/ruby/1.8/set.rb:194:in `each_key' from /usr/lib/ruby/1.8/set.rb:194:in `each' from /usr/lib/ruby/1.8/vim/addon-manager.rb:80:in `remove' from /usr/lib/ruby/1.8/vim/addon-manager.rb:75:in `each' from /usr/lib/ruby/1.8/vim/addon-manager.rb:75:in `remove' from /usr/bin/vim-addons:264:in `send' from /usr/bin/vim-addons:264 The problem is that the while-loop on line 66 is written "while paths.size", which, in Ruby, will always evaluate to be true, because even the value "0" is considered true in Ruby. See: http://ruby-doc.org/docs/Newcomers/ruby.html#boolean Were it not for a fluke exception-handling within the loop, and exception raising in the case when the ~/.vim directory is a symbolic link, this would actually result in an infinite-loop. The loop should be changed to "while paths.size > 0". This bug affects the upstream Debian package of vim-addon-manager, too.
