Description Lucious 2019-04-25 01:19:01 UTC 
Description of problem:

If you attempt to 'dnf install /path/to/rpm" or "dnf install partial-program-name" the terminal session will hang, as soon as, you press TAB requiring a Ctrl-C to break the process. 

My guess is dnf is attempting to search the repos for tab completion but it never finishes. I tried this on fedora 29 Workstation, it still hangs but briefly, then proceeds to finish tab completing the rpm name. Or it will make a guess from the repos.

Version-Release number of selected component (if applicable):

dnf: 4.2.2
Fedora 30 Workstation Beta


How reproducible:

Happens every time.


Steps to Reproduce:
1. Download an rpm.
2. Attempt to install the rpm using dnf by tab-completing the name.

or

Htop example.
1. Type "sudo dnf install hto"; Press TAB



Actual results:

The tab-complete does not resolve a name. CPU spins up but nothing happens

Expected results:

I expect the rpm name or program name to complete.


Additional info:

I know it's not as common to work with individual rpms, but brother print/scan drivers require them. Also, if someone is packaging an application for fedora and wants to test install with dnf. 

rpm -i package.rpm 

Still works fine.
