[gentoo-user] Packages from overlays

[gentoo-user] Packages from overlays

[Willie Wong]

Hi list, 

  Is there a way of finding out whether I have packages installed on
  my system from a given overlay? I am asking because I noticed that
  some of the packages I've installed (such as GoogleEarth) from
  overlays had been incorporated into the official portage. I would
  like to 'unsubscribe' to overlays that doesn't have packages that I
  need. 

Thanks, 

Willie

You may want to reconsider this.  I have googleearth installed here and
it doesn't get along well with portage and it's digest checking.  Of
course, it doesn't like my dial-up either.  LOL

>From what I understand Google doesn't allow Gentoo to mirror the souce
tarball.  After you install it and sync later on, if Google has changed
something, you get a digest error.  It will delete the tarball from
distfiles too.  I'm on dial-up and that sort of ticks me off,

The way I got around it is to manually delete it from my world file. 
That way it doesn't check the digest.  Some guru may have a better way
to do this but this is what I have ran into with googleearth.  May want
to check farther before you run into the same thing I did.

Hope that helps, and makes sense.  Sometimes I don't.  LOL

It would appear google has updated their package without changing the
name, and portage has not been notified of this change. If you want it
to work, delete the digest file for it in
${PORTAGE_DIR}/x11-misc/googleearth/files/digest-googleearth-4_beta
and then re-generate it with
ebuild ${PORTAGE_DIR}/x11-misc/googleearth/googleearth-4_beta digest

and that should fix you up. I found it still compiles and runs fine *shrugs*

True, you hit the problem right on the head.  That is exactly what they
do.  But what I had noticed is that they change that thing a lot.  Since
I am on a really slow dial-up here, I check for updates, sync, every
couple days or so.  While I know that it comes from Google and I don't
question the tarball from a security point of view, portage still
complains about it each time and deletes it for me, since it thinks it
is a security problem.  That would normally be a great idea but then I
have to download it again, which takes a little over two hours for me.
I get about 10Mbs a hour here.  < goes to have a good cry >

Plus, it is a pain in the butt to have to manually do the digest thing
every time I sync up too.  My solution was to remove it from the world
file, since portage had already deleted the tarball and I didn't want to
download it again to do a oneshot install.  Now the only drawback is
that --depclean -p tells me it is not needed since it is not in the
world file and is not a dependancy.  I do that manually anyways so it
doesn't matter.

I'm no guru but if he wants it out of overlay, he may want to emerge it
as a oneshot at least.  Then just check for updates on occasion.  I had
to use the --digest option too when I installed it.  That way it assumes
it is OK and doesnt' check it.

Hope that makes sense.  Maybe . . . .   LOL

It's the other way around. He gets a digest verification error *because* 
portage was notified. The old ebuild gets removed because it's tarball is now 
unavailable upstream (and a new is available under the same name).

Not much of a fix. Just gets the old version. Of course it still compiles and 
runs. It hasn't changed at all.

I can't help wondering. If you don't have the bandwidth to upgrade when there 
is an upgrade. How useful is googleearth to you then. It's not like it 
doesn't require any bandwidth just to run... Also the more often you sync the 
more bandwidth you need with Gentoo in general..

I only got it once.  :/

Well, I tried the other way around, not updating as often but I have it
all planned out now.  The problem with waiting is that it builds up.  I
would hate to sync after a month or so then find out OOo and KDE was
updated, plus some otehrs for good measure.  Just OOo takes me about 24
hours to download.  Yes, I get the compiled version.  This is Gentoo
after all.  ;-)  Plus, I ran into a config nightmare.  To many updates
at once for me.  I'm not a guru.

The way I do is this, I connect around 10:00PM, check my emails and
sometimes the weather.  Then I start the sync process and tell it to
fetch the new stuff afterwards, got to love the &&.  While it is doing
that, I go for my nightly soak in the tub.  I have a skin disorder and I
have spent several hours in the tub.  This works well because at the
very least the fetch has started and sometimes it has been fetching for
a while.  It depends on how many things are updated and how long I soak. 

As for googleearth, well, dial-up has taught me patience.  It works, it
just takes a really long time to get there.  Sometimes another soak in
the tub.  LOL

Doesn't really seem to be related to OPs question so it probably should have 
been a new thread, however...

The real issue is that google refuse to rename the tarball when they release a 
new version. The secondary issue is then that Gentoo can't rename it on their 
own mirros since they aren't allowed to redistribute it.

Without your consent??

Understandable. You should, however, realize that it is an actual upgrade 
you're rejecting in this case.

I don't really have a better suggestion if you don't want the upgrades. 
Redigesting it as Kent suggests seems rather pointless as you would just be 
reinstalling the old version (while tricking portage into believing you get 
the newer version (as if that mattered ;)) with no actual gain.

Portage currently does not store any information about where a package was 
installed from. Therefore the best you can do is manually inspect the output 
of `eix --installed-overlay`. It will show all packages where the version you 
have installed exists in any overlay (and you can see if they exist in the 
tree too). That, however, only implies that they might have been installed 
from that overlay..

It does require app-portage/eix-0.8.x. Also if you use update-eix-remote you 
better (re)move the eix database (/var/cache/eix) and regenerate the database 
with `update-eix` first or you will get a lot of false positives. IOW you 
need the eix database to only contain installed overlays.

This approach seems to work ok with eix 0.6.4, but the switch is just
--overlay

Oh, that is too bad. 

I think I can live with having extra overlays living on my testing
box. 

Just a thought though: would the following be advisable/work?

Could I just delete those relevant overlays (either layman -d or
perhaps commenting them out in the relevant parts of the make.confs)
and see if emerge complains about non-existant packages in my world
file or unsatisfiable dependency? IIRC, I shouldn't have any packages
installed from overlays for more recent versions than portage offered;
I only install them from overlays when the ebuilds are not in portage
at all.

Unless you have a lot of overlays it not really *that* bad.

# PORTDIR_OVERLAY="" emerge -ep world >/dev/null

!!! Ebuilds for the following packages are either all
!!! masked or don't exist:
dev-util/regex-coach app-portage/pfs net-analyzer/ksniffer kde-misc/kcpufreq 
app-portage/gentoo-stats

So yeah, that works. :)

IMO the real solution for your problem, however, is a package manager with 
true multiple repository support allowing you to control from which 
repository you want to install a given package. I'm not sure if pkgcore is 
there yet (since I don't follow it too closely), but paludis is. Paludis thus 
also stores information about which repository a package was installed from.

With portage if the same ebuild or eclass exists in any of your overlays and 
in the tree then the one in the tree will just be hidden to portage behind 
the overlay. That's why they are called overlays in the first place.. ;)

I use the attached script to look for packages installed from overlay
where the same version is available in portage. Run it with the -v option
to see a diff between the two ebuilds, otherwise it just reports names.

No problem, I wrote it for my own use some time ago. It uses colordiff to
produce the diffs so either

1) Emerge colordiff
2) Edit the script to use diff instead
3) Don't use the -v option
