Bug 128492 – packages in package.provided are not considered for blocks

• Status: RESOLVED INVALID
• Product: Portage Development

[Description Petteri Räty (RETIRED) 2006-04-02 03:37:20 UTC]

To reproduce:
1. put a package to package.provided
2. use emerge -pv on an ebuild that blocks the package you put to package.provided
3. emerge let's you install the blocking package

Solution:
packages in package.provided should be handled like packages installed by Portage

I'd argue that this is not a bug: Most blockers are there because 2 packages install the same file in the same location. If you install a packages by hand (and put it in package.provided) you usually install it in a different location.

So - you install the packages in other locations so that other ebuilds from portage wouldn't find them? Hmmm. I don't. 

[Comment 3 Simon Stelling (RETIRED) 2006-04-02 05:10:08 UTC]

you can put 'it' (e.g. being a binary or a shared lib) in other locations and it will be found nevertheless, that's what we have PATH and LDPATH for.

[Comment 4 Jakub Moc (RETIRED) 2006-04-02 05:15:59 UTC]

Yeah, you can put 'it' in any location and set PATH and LDPATH accordingly and break the stuff that blocks a particular version of something or blocks even the package completely b/c it breaks when it gets installed at the same time. ;) 

The current behaviour is inconsistent, that's about it. Quick example? cryptsetup/cryptsetup-luks. I'm sure there are quite a few of them.

[Comment 5 Simon Stelling (RETIRED) 2006-04-02 05:17:58 UTC]

i didn't say this isn't a bug - i just said your reasoning sucks :P

[Comment 6 Marius Mauch (RETIRED) 2006-04-03 12:53:34 UTC]

I don't consider this a bug, if you put something in p.provided you take full responsibility for it. You can still use collision-protect to avoid file clashes.
And if p.provided packages would block in-tree packages without any real reason (like using a different prefix) people will get angry.
Basically portage shouldn't act like it knows things it doesn't know (in this case package identity).
