Bug 177934 – app-portage/genlop-0.30.7 Use of uninitialized value in pattern match (m//)

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Michał Kiedrowicz 2007-05-10 15:14:32 UTC]

It seems that genlop doesn't parse command line arguments properly. Combination of -r and -i arguments give warnings about uninitialized value and doesn't look for specified package.

Reproducible: Always

Steps to Reproduce:
1. # geblop -ri
2. # genlop -ri gcc
Actual Results:  
# genlop -ri

Works just fine here. What's your bash version?

[Comment 2 Michał Kiedrowicz 2007-05-10 15:25:10 UTC]

$ bash --version

Not reproducible...

$ emerge -pv genlop bash

These are the packages that would be merged, in order:

Also, eh... this is perl, not bash. I guess I need more beer. :P

That patch is not working for me... could you post you /usr/bin/genlop file please?

[Comment 9 Roeland Douma 2007-05-12 15:40:29 UTC]

When I use that file and i do an './genlop -ir" i just get the info screen of when i do 'genlop -i'. No warning but also not the info that i need...

'genlop -i' is inproper use of this program (no packages selected), 'genlop -ir' also is inproper (-r searches for sync history, -i displays info about selected packages). I've only forced displaying normal info scren when (-i or -t) and -r are combined together, because it is normal genlop's behaviour (like dispaying info screen when doing 'genlop -i'). I didn't put any warnings, because genlop normally doesn't show any warnings about inproper use of arguments.

I can put show warning about '-r and -i combined together' if You think there should be.

Also, I don't understand what's 'the info You need'.

[Comment 11 Roeland Douma 2007-05-14 07:19:36 UTC]

You are right that doing genlop -r and genlop -i foo work. But i was trying to reproduce the steps in the first post... But other than that it is indeed working :)

[Comment 12 Michał Kiedrowicz 2007-10-10 20:32:42 UTC]

I can't reproduce this issue on genlop-0.30.8-r1, so this bug can be closed.
