Segfault when dropping Alpm after calling Db::groups() #31

Closed brokenbyte closed 1 year ago

brokenbyte commented 1 year ago

Minimal reproducible example:

#![allow(unused)]
fn main() {
    let conf = pacmanconf::Config::new().unwrap();
    let mut alpm = alpm::Alpm::new2(&conf.root_dir, &conf.db_path).unwrap();
    alpm_utils::configure_alpm(&mut alpm, &conf).unwrap();
    alpm::Alpm::new(conf.root_dir, conf.db_path)
        .unwrap()
        .localdb()
        .groups();
}

I can also reproduce this in the latest version of paru (commit 257e01155501e3f93ed218f3853156a030b20c58) so I don't think it's from how I'm setting up the Alpm struct. paru patch file:

Thanks. Don't know how no one noticed before. Fixed and return type has been changed. Pushing as a bug release as no one could actually use this function before anyway so the breaking change is irrelevant.

Also just noticed new2() is a function that exists apparently. I think this may have been a test function that accidentally hit release whoops.
