[gentoo-user] Confused with the --oneshot option of portage.

[gentoo-user] Confused with the --oneshot option of portage.

[Jonathan Chocron]

Hello !

I am getting a bit confused with the --oneshot option of portage (as the title 
says).

I need to do a little bit of portage history before asking a my question, 
sorry. If the following is wrong, please correct me !

Once upon a time, in the happy land of portage, there was a file named world. 
This file knew of all the packages that inhabited a planet called gentoo 
system.

Then, this file was cruelly deleted by the gods known as gentoo devs. It was 
not cruel or anything, it was just that the file had served its purposed and 
was now to be regenerated every time someone invoked "emerge -Dup world".

The world of the packages became two-tiered : some of them, the noble packages 
were present in world, some of them, the working class, known as 
the "libraries" did not have that privilege. The terrible truth was that they 
slowed portage down, and, as they were servants to the noble package would 
find their way in an "emerge -Dup world" anyway by the mechanism of 
dependency.

Ok, I am sorry about the above, I've only slept 2 hours.

So, here are my questions : With world being autogenerated 

- If I emerge a library, like xvid with "emerge xvid", it will end up in 
world. How do I revert that ? Do I have to emerge -C xvid and then 
emerge --oneshot xvid ?

- If I emerge -Dup world, will the listed packages alkl end-up in world ?

- If I first emerge a package, for example kmail, with emerge kmail, and 
later, during an upgrade phase, do an emerge --oneshot kmail, will kmail be 
removed from world ?

Thanks to those who had the patience to read this. And more thanks to those 
who will answer !

Regards,

-- Jonathan.

Not sure I would call it 'autogenerated'.  It is more accurate to call
it the list of packages that you have merged without the --oneshot
option.

That is one way.  You could quicken this with "quickpkg xvid; emerge
-C xvid ; emerge --oneshot --usepkgonly xvid".  Or just edit
/var/lib/portage/world by hand to remove xvid.

> - If I emerge -Dup world, will the listed packages alkl end-up in world ?

No.  Only the packages you specifically merge without --oneshot end up
in world.  Dependancies of world or system packages that show up when
you add -D/--deep are not added to world...

No.  Only unmerging the package, or ediiting the world file, will
remove it from world.

Thanks, that shed some light !

As long as I've been using gentoo (not long, since 2004) this file has 
always only listed packages you explicitly installed, not any of their 
dependencies.  Although, some misguided users accused it on containing all 
their packages.

*I* still have this file.  It did *MOVE* at some point but it current 
incarnation is at /var/lib/portage/world.  I've edited the file manually a 
number of times followed by a emerge -A --depclean to clean up my system.

The file that changed from existing to being auto-calculated was the "edb 
cache" IIRC.  From what I understand, these isn't a way to auto-calculate 
world from what's stored in /var/db/pkg and /var/lib/portage (other than 
world and world.backup).

World isn't auto-generated.

Edit /var/lib/portage/world.

Nope, because they weren't listed on the command-line.  Just like when you 
emerge kde-meta you only get one package added to world not 300.

That's one for the portage devs, but I don't /think/ so.

I'm not a dev, but I'm sure that it will *not* be removed from world. I
always use --oneshot for updates.

That's correct. If you use --oneshot, world is not touched at all,
nothing is added or removed.

There isn't, AFAIK, a portage option to remove a package from world,
although adding is easy with emerge -n.

I hope this will help.

1) It apears there is a way to pull packages out of the world set. :)

>From 'man emerge', section "FILES":

=============
       /var/lib/portage/world
              Contains a list of all user-specified packages.  You can safely  edit 
this file, adding  packages that you want to be considered in world
set updates              and removing those that you do not want to be
considered.
=============


2) I'm not sure what happens when using

"emerge --oneshot already-isntalled/package-higher-version"

but it is easy to check this out by looking in /var/lib/portage/world before and
after emerge finishes it's job.

That has to be done manually by removing the appropriate line
from /var/lib/portage/world. The package will then still be installed,
but will not be updated with emerge -u world

That's already been covered, I was referring to a portage option, a
complement to -n.

There was still nothing, but you could see it better.

From `man emerge`. Use with care and always investigate with --pretend first.

--depclean
	Determines  all packages installed on the system that have no explicit reason
	for being there.  emerge generates a list of packages which it expects to be
	installed by checking the system package list and the world file.  It then
	compares that list to the list of packages which are actually installed; the
	differences are listed as unnecessary packages and then unmerged after a
	short timeout.   WARNING:  Removing  some packages may cause packages which
	link to the removed package to stop working and complain about missing
	libraries.  Re-emerge the complaining package to fix this issue.  Note that
	changes in USE flags can drastically affect the output of --depclean.

> on it :(

Correct.
