 Posted: Mon Apr 11, 2005 10:39 am Post subject: any new portage ideas? |
 |
|
Okay guys, I have been thinking about ways to improve portage and I came up with a couple of things.
1. a feature to prompt the auto addition of mask flags to your package.keywords. So that if you try to emerge something thats masked, it gives you some warning about masked packages and asks if you would like to add these packages to your packages.conf, and then does so.
2. Perhaps this is a bit far fetched, but I think it would be cool to have a wishlist type feature. So that if for instance I want totem 1.1 but there either isn't an ebuild for it, or its masked and I wan't to wait until it hits stable. you could say emerge -wish totem-1.1 and after it hit portage, it would be emerge when you did an emerge -u world.
3. Unmerging package improvements, I understand the difficulties in dependancies and such, but it would be nice if portage would calculate the dependancies of an app that you are unmerging, and if it can't find any other apps that need it, ask if you would like to emerge that as well. Additionally, when you unmerge something with config files, those aren't removed afaik. I know that some people might want to save those settings in case they were to emerge that app again, so. What if portage either prompted for the option, i.e. 'would you like to remove config files?' or if it automatically dumped them to a /etc/config.old/ where they could be retrieved if needed or cleaned out by the user if not. That way if you want to say, remove alsa you don't need to hunt for the config files scattered across /etc and /etc/conf.d and /etc/init.d/
4. an easy way to see what you have installed on your system, I know I can check the world file, but I can never remeber where the damn thing is, an emerge -list world would be much better imho
what do you all think? any other ideas? |

| Code: | | emerge -v gentoolkit && qpkg -I -v |
point 2 seems sensless to me, if i want a masked package, i can install it, if the package is not avail. i remeber this alone.
the rest seems ok though.

Is there a way to see the changelog of the files, not of the ebuild?

I think he meant something like the following:
Say, for example, you emerge a package A. In doing so you install packages B and C as dependencies. Then let's say you also install package D that depends on package C. Then when you unmerge package A, Portage should also see that it installed package B which onthing else depends on, and so it should unmerge B too. It should then check and see that package C is required by package D, so package C stays on your system.

Sounds like emerge --depclean: | emerge --help wrote: | --depclean
Cleans the system by removing packages that are not associated
with explicitly merged packages. Depclean works by creating the
full dependency tree from the system list and the world file,
then comparing it to installed packages. Packages installed, but
not associated with an explicit merge are listed as candidates
for unmerging. WARNING: This can seriously affect your system by
removing packages that may have been linked against, but due to
changes in USE flags may no longer be part of the dep tree. Use
caution when employing this feature. |

what I mean is, when you unmerge an app, it could go through the list of its dependancies, and for each one check your whole tree to see if anything you have emerged needs it, and if not, give some message asking 'package x does not seem to be requred, would you like to remove it?'
with some warning of course similiar to depclean. |

emerge depclean is where I got the idea for this, but with two subtle differencess. This would happen after a package is demerged, for convenience sake (who really wants stuff they don't need on their system) and it would prompt per package. That way if you know that you need package A, and it doesn't think you do, you tell it that you want to keep it.
afaik with depclean, it's all or nothing, which I think is why it has a tendancy to break people systems. |

What he is talking about is not depclean, depclean is a very stupid way to actually handle the problem because it is affected too greatly by the use flags and not the way the program was installed on the system, besides it tries to do this to the entire system in one shot which just isn't nice, when it needs to be done inline during an unmerge. Basically its what depclean should be.

Then I would suggest fixing depclean so that it doesn't screw up when use flags has been changed (though this is not as easy as it sounds), and adding AUTODEPCLEAN as an option to make.conf (simmilar to AUTOCLEAN now).

1. Might work, but you might end up with a ton of items there you have no clue what is
2. is just silly, you can just check after a emerge sync
Now what portage really need is Clippy!

My wish is somewhere along the line of emerge --depclean and some other unmerging ideas. I would like to be able to unmerge say Xorg and all the dependecies along with it....if I so choose using something like | Code: | | emerge -C xorg-x11 --onlydeps |
or something like that. If I screw up my system I guess that is my fault.
Right now I would like to get back down to the "base system" before X (I guess a step up from a Stage3 install) without having to manually uninstall everything. |

What you just mentioned is what portage already does. If you emerged an older version of totem, totem 1.1 would be installed whenever it was stable.

true, and I know this is a silly idea, but for example, totem 1.0 requires nautilus, and I don't want nautilus. totem 1.1 however, does not require it. So I am going to wait until totem 1.1 hit portage to emege it. |

Just because an ebuild lists a dependency doesnt necessarily mean its actually required. Keep in mind that everything is always evolving and ebuilds are just a way of managing dependencies, not a end and be all of a program...
I also wanted to say that your world file is not indicative of what you have installed on your system. An emerge -pe world would be a much better list of all the packages you have installed. If you were to install GNOME, you would find that only the meta ebuild gnome would be listed in your world file. The 50+ programs that make up GNOME, would not be in there...
