Bug 618860 – kde overlay should contain metadata/md5-cache

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description anonymous 2017-05-18 17:47:46 UTC]

kde overlay should contains metadata/md5-cache.

Because md5-cache is missing every eix-update or resolve dependencies very slow, especially on old PC or notebooks.

Proposal: add git-hook to every developer that will run
egencache --update --repo kde
before any push.

Reproducible: Always

[Comment 1 Michael Palimaka (kensington) 2017-05-20 07:36:35 UTC]

While I agree metadata would be nice, there are two main problems I see:

1. It's generated data which doesn't need version control, so would unnecessarily bloat the repo

2. Because it is a child of gentoo.git, any eclass changes there (where there are instances of that eclass being inherited) would invalidate relevant parts of the overlay cache

To resolve #1, instead of including metadata in the main/source repo we could offer a separate "sync" repo (such as we already have for gentoo.git - https://gitweb.gentoo.org/repo/sync/gentoo.git/). I'll ask mgorny about the feasibility of this.

I've been informed that this already exists! https://github.com/gentoo-mirror/kde

Good! Can this be default repo when I'm adding overlay through layman?

[Comment 4 Michael Palimaka (kensington) 2017-05-21 12:32:43 UTC]

I'm not sure if we could replace the existing repo - will it cause conflicts for users who already have it added using the old repo? We could add a new entry "kde-sync" or something.

I added kde-sync:

[Comment 6 anonymous 2017-06-04 16:19:33 UTC]

Now I get warning when use kde-sync overlay:

!!! Invalid PORTDIR_OVERLAY (not a dir): '/var/lib/layman/kde'
!!! Section 'kde-sync' in repos.conf has name different from repository name 'kde' set inside repository

[Comment 7 Michael Palimaka (kensington) 2017-06-05 13:34:18 UTC]

OK, that's a shame. I've backed it out now:
https://gitweb.gentoo.org/data/api.git/commit/?id=b6a795886a91f14e7cdebbff5d42a4e9b26feac4

I was pointed to this doc about how it's recommended to use the sync repos instead:
https://wiki.gentoo.org/wiki/Project:Repository_mirror_and_CI

The example config and the text contradict each other. Could you try reversing the order of the repositories.xml entries?

Can you take a look at this mgorny? Apparently it's not working.

Well, I couldn't reproduce the issue but I've updated the wiki article nevertheless. There is really no reason to keep using the original api.g.o .xml if mirrors are used, so just removed it and put the mirror list alone.
