I've installed an arm-elf-eabi crossdev target and am now upgrading my machine (just a normal emerge -avDuN --with-bdeps y world) and it wants to install a new slot of newlib. This would be fine, except that the new slot's files are the same as the old slot's files: * This package will overwrite one or more files that may belong to other * packages (see list below). You can use a command such as `portageq * owners / <filename>` to identify the installed package that owns a * file. If portageq reports that only one package owns a file then do * NOT file a bug report. A bug report is only useful if it identifies at * least two or more packages that are known to install the same file(s). * If a collision occurs and you can not explain where the file came from * then you should simply ignore the collision since there is not enough * information to determine if a real problem exists. Please do NOT file * a bug report at http://bugs.gentoo.org unless you report exactly which * two packages install the same file(s). See * http://wiki.gentoo.org/wiki/Knowledge_Base:Blockers for tips on how to * solve the problem. And once again, please do NOT file a bug report * unless you have completely understood the above message. * * Detected file collision(s): * * /usr/arm-elf-eabi/lib/libm.a *

And yes, I know that these are only claimed by one package, but it's the second slot that's causing the problem. Reproducible: Always Steps to Reproduce: 1. Install arm-elf-eabi target with newlib-2.0.0 2. Upgrade to newlib-2.1.0 3. Actual Results: Fails with file collisions. Expected Results: Either doesn't install as a second slot (which would be just fine) or uses different filenames for the new slot.
has nothing to do with crossdev. you can manually change the SLOT yourself, or temporarily set FEATURES to ignore collisions, or re-install the toolchain.
With regards to your suggestions: 1. I do not intend to unset collision-detect. This sounds like about the best way to screw up my system royally. 2. I would really really like to avoid reinstalling the toolchain from scratch because that was horrific the first time and I see no reason to believe it will be better this time. **3**. About the SLOT: I am now even more confused because both packages have SLOT="0", shouldn't that mean that the new package should not be able to be installed alongside the old package? I have attached the emerge results and the two relevant ebuilds. Strangely enough if I try to emerge both the package that I already have installed as well as the new package ebuild chokes, telling me that I'm trying to install two packages in the same slot. However, if I just try to upgrade the package it seems to have forgotten about this problem and wants to install the package to a new slot (at least until it gets to the install stage). I would have to say that this seems to either be a bug with crossdev or portage however and not a problem with newlib. You have offered no reason for me to believe that this is not a crossdev issue. I have also offered no reason to suggest it is specifically a problem with crossdev, however I don't believe it's a problem with newlib.

P.S. I also don't understand the new title. I get that you're trying to make it newlib's problem but what do you mean by "SLOT change"? I see not "change".
from your own logs: * cross-arm-elf-eabi/newlib-2.0.0:arm-elf-eabi::x-portage [ebuild R *] cross-arm-elf-eabi/newlib-2.0.0:0::x-portage [2.0.0:arm-elf-eabi::x-portage] USE="nls unicode -threads" 0 kB so clearly your currently installed newlib does not have a SLOT=0, it has "arm-elf-eabi"
I don't follow, I looked in the newlib-2.0.0.ebuild file and it says SLOT="0". Where are you getting "arm-elf-eabi" from? I thought all slots had to be numeric, but honestly I don't know much about slots except that they allow you to install two versions of the same package.
Okay, I've done some more research and I think I've found the problem. Looking at the cvs history it appears that the change made to newlib-2.0.0 changed the SLOT of an existing package (http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-libs/newlib/newlib-2.0.0.ebuild?r1=1.1&r2=1.2). Now is it just me or is that an incorrect thing to do. My understanding is that there should at least be a -r1 type bump and likely in this case it would have to block anything using the old SLOT convention (basically <2.0.0-r1). Then the 2.1.0 would have to block the same things. Again, I don't really know very well what I'm talking about, just speculating based on other things I've seen done.
(In reply to Alex Orange from comment #10) no revbump would have helped. you'd be in the same exact spot. a blocker might have helped, but i can't reproduce here. portage will migrate the content for me when the SLOT changes.
What do you mean "migrate the content"? Also, I was suggesting that it would need to be a rev-bump + blocker to solve the issue. I was just saying that it seems like to be kosher that it would need a rev-bump for a change like this. Though I want to point out that I don't know that for sure.
as i said, the revbump wouldn't help at all. portage doesn't care what the -r# is as the SLOT values are different. portage-2.2.8 for me had no problem replacing newlib-2.0.0:${CHOST} with newlib-2.0.0:0. not sure why. i'm not sure a blocker is even feasible as it needs to block all values where SLOT is not 0.
Yes, but if you consider anything <2.0.0-r1 to be suspect (as possibly being in slot other then 0) then you can just block them. Assuming everything >=2.0.0-r1 is restricted to slot 0 then you've assured that everything not in slot 0 is removed. I'm going to reopen this in hopes that whoever handles newlib looks at this problem.
Created attachment 368200 [details, diff] Patch to newlib-2.1.0.ebuild to fix problem. This fixes the issue for me, and I believe it would be an improvement on what is there right now.
should be all set now in the tree; thanks for the report! Commit message: Add a blocker against older SLOTs to help with upgrades http://sources.gentoo.org/sys-libs/newlib/newlib-2.2.0.ebuild?r1=1.3&r2=1.4
