[Github-comments] [geany/geany] Domain socket error: Not working via sudo is a geany bug, not a feature or bug in sudo (#1150)

[Colomban Wendling]

As I reply everyone raising this "bug", get a properly configured `sudo`.  Even though I don't recommend using Geany as root, I can just fine run `sudo geany` on my Debian machine and it works flawlessly (as far as I can tell without doing it daily, though), whether or not I have other Geanys running.  It properly uses */root/.config/geany* as the configuration directory.

*Anything* that would lead to another user (including root) to writing in a user's home directory should be avoided.  If you *did* write there as root, the user would be left with root-owned file in his home, files he couldn't modify.  That's not a good thing.

And while I don't want special code for handling `sudo` use, I don't think any is needed: proof being I can use `sudo` just fine on my machine.  Yes, Debian does have `Defaults env_reset`.

If you *really* want us to change something, you'll need to detail why you'd need inheriting the environment (including `HOME` and `XDG_*`, and possibly other) in your sudo session, and what you'd want us to do to fix it (by that I mean actual changes, not "fix it").

If "many other GUI tools" work, it might be for a number of reasons, one possibly being that they use DBus (anything using *dconf* comes to mind), which may or may not use `$USER` rather than `$HOME`/`$XDG_*`.  Or other special handling.  Or possibly simply not have to do any IPC and happily mess up your user's home directory.
If really other tools to something meaningful and it's not a hack, maybe it could be a basis for proposing a change.

Out of curiosity, do you have root-owned stuff in your dotfiles? `(cd && find -path './.*' -user root)`

*I'm not closing it just now, but I still do consider this invalid at least for the moment*
