With eselect version 1.2_rc1 I get collision error for eselect-news

Code: Select all

collision-protect>  * Checking for collisions...
collision-protect>  * /usr/share/eselect/modules/news.eselect already exists in /
collision-protect>  * Package collides with existing files

as the file news.eselect gets installed by the new eselect version.

As a result Paludis tries to install eselect-news time after time as it itself depends on it

Code: Select all

* app-admin/eselect-news [N 20080320]
    Reasons: *sys-apps/paludis-0.38.2:0::installed

Should the paludis ebuild be tweaked or what?

Remove eselect-news, reinstall eselect and reinstall paludis. This works on my system.

[loftwyr]

The only problem is that paludis-0.38.2 has a depedency on >=app-admin/eselect-news-20071201.

That needs to be removed.

EDIT: And it has in both the gentoo and paludis-overlay repositories.

Actually, the dependency is (from paludis-0.38.2.ebuild):

Code: Select all

|| ( >=app-admin/eselect-1.2_rc1 >=app-admin/eselect-news-20071201 )

So either eselect-1.2_rc1 or eselect-news will satisfy it.

This error usually indicates that one of the packages you are trying to
install requires that another package be built with particular USE flags
enabled or disabled. You may be able to work around this restriction by
adjusting your use.conf.

!!! Error: Can't load module news

I don't know if it's that's just me or the gentoo tree, but this kind of issue seem to happen more and more often, and it's so annoying to 'fix'.

Is there any way to have a usefull output ready to be pasted into /etc/paludis/use.conf?

Hmm so I need to reinstall both, paludis and portage to depend on just eselect, because otherwise it gets installed again and blocks again here.

[Phlogiston]

Oh and I can't uninstall eselect-news:

Code: Select all

checking for eselect env... yes

So whats the proper fix for this? (apart from not upgrading eselect)

[mikkoc]

I have a strange problem on my new gentoo install.
Basically I'm trying to rebuild the 9999 kde packages from kde-testing overlay.
The problem is that the sources aren't updated because paludis thinks one hour hasn't passed since last fetch:

Code: Select all

 * Fetching disabled since 1 hours has not passed since last update.  
 * Using existing repository copy at revision 1017226.                
 *    working copy: /usr/portage/distfiles/svn-src/kdelibs/kdelibs

But ls -la says the date is Aug 30, so 4 days ago. Any help would be appreciated.

[mikkoc]

That works, thanks. But it's more like a workaround, not a long term solution

[Rob Paxon]

So whats the proper fix for this? (apart from not upgrading eselect)

I did (roughly):

Code: Select all

paludis -u --permit-unsafe-uninstalls app-admin/eselect-news app-admin/eselect
echo "app-admin/eselect-news" >> /etc/paludis/package_mask.conf
paludis -i --preserve-world app-admin/eselect

I then did...

Code: Select all

paludis -ip --preserve-world sys-apps/portage sys-apps/paludis

...and received no dependency errors. I then removed the mask on eselect-news, did another pretend, and neither app was trying to pull it in anymore.

For good measure I did "paludis -i world" and "paludis -i everything", with nothing attempting to pull in the unmasked eselect-news. The built-in news module seems to work just fine with Paludis:

Code: Select all

 * No updates needed

Updating world file

* skipping everything (special sets cannot be added to world)

 * No unread news items found

 * Searching for configuration files requiring action...
 * No configuration file updates required

[smithpeter018]

I checked it its not reliable

[Ant P.]

How do I fix this?

Code: Select all

$ time emerge -DptvuN world --with-bdeps=y
...
real	0m3.587s
user	0m3.466s
sys	0m0.142s

$ time paludis -pi everything
...
real	0m25.297s
user	0m23.556s
sys	0m4.411s

I've triple-checked my write_cache, names_cache and cache settings. I must be doing something wrong if the package manager itself takes longer than most of my compiles, right?

[costel78]

First of all: I didn't use paludis before, currently I use portage. And I don't want to start a flamewar.

Here is my question:
GOAL: a more efficiently use of CPU during compile
CPU: Intel Core i7 860, 4 core HT enabled
ACTUAL situation: parallel build with-portage - MAKEOPTS="-j8 --load-average=10" and this command: emerge --jobs=4 --load-average=11 --keep-going -e world. world-set contain ~2400 packages. /var/tmp/portage is mount as tmps in RAM. I gain only ~20% improvement comparative with my old E8400 processor. Most of time CPU does get used more that 30%-40% and that's annoying.

QUESTION: As far I know paludis lack of parallel-build feature. Despite of this, if I switch to paludis do you think I will gain an important improvement during emerge -e world equivalent ?

[gregy]

Just another question:
Is it normal that after I run

Code: Select all

paludis -u =sys-kernel/vanilla-sources-2.6.31_rc4

and after it finishes succesfully I still have /usr/src/linux-2.6.31-rc4 directory which takes ~150MB of space?

[Ant P.]

Just like Portage, Paludis won't remove files it doesn't own (i.e. your compiler output). You have to delete them yourself.

[gregy]

Just like Portage, Paludis won't remove files it doesn't own (i.e. your compiler output). You have to delete them yourself.

Ok, wait a minute. I just checked and for example "emacs-22" (in /usr/bin) is owned by root. So if I decide to uninstall emacs this file will stay there?

[loftwyr]

No, that means that the files created after installing the packages (like the resumes of building a kernel) aren't owned by the package and paludis won't remove them. Normal binaries and other things directly installed by paludis are tracked and removed.

[gregy]

Oh, now I get it. Thank you very much for explaining it.

[Paczesiowa]

is there some description of dependency resolution algorithm for paludis (without reading c++ code)? because every now and then I run into problems that I don't understand.

here's another one:

Code: Select all

desktop ~ # paludis -i baselayout openrc -p
Building target list...                    
Building dependency list: ... 14 steps     

These packages will be installed:

* sys-apps/baselayout [R 2.0.1] <target>
    Reasons: sys-apps/openrc-0.4.3-r3:0::gentoo
    -build build_options: -optional_tests -split strip -trace
* sys-apps/openrc [R 0.4.3-r3] <target>                      
    Reasons: sys-apps/baselayout-2.0.1:0::gentoo             
    -debug -ncurses -pam unicode build_options: -optional_tests -split strip -trace

openrc-0.4 should suffice

The above snippet of code will pull in both of the following:

Any version of baselayout with a major version number of 1 AND openrc greater or equal to 0.4 That snippet is not an or condition...
