Fixes #37606 - Drop old CentOS installation media #10227

ekohl · 2024-06-27T17:06:56Z

The host mirror.centos.org is gone now that CentOS < 9 is EOL. It includes a migration to simplify the name, but doesn't include migrations to remove old entries. That is up to the user because they may have modified them and still use them.

@ShimShtein do you want me to add this to my list of reviews to go over as part of the mentorship?

chris1984 · 2024-08-05T15:16:48Z

@ekohl did you want me to look for areas that were missed and test(provide a patch), not sure if you just didn't have time or was there another reason this was in a draft?

ekohl

not sure if you just didn't have time

This, though I think it would be great to do this before Foreman 3.12.

I left a comment with what I at least know as one TODO.

-    },
-    {
-      :name => "CentOS Stream 9 mirror",
+      :name => "CentOS mirror",


I think this may need a DB migration to rename the existing entry.

Yup, this will definitely require a migration.

On fresh dev machine:

[2] pry(main)> Medium.where("name like '%9%'").all => [#<Medium:0x00007f08ff4f6aa0 id: 3, name: "CentOS Stream 9 mirror", path: "http://mirror.stream.centos.org/$major-stream/BaseOS/$arch/os", created_at: Tue, 30 Jul 2024 10:43:46.058948000 UTC +00:00, updated_at: Tue, 30 Jul 2024 10:43:46.058948000 UTC +00:00, media_path: nil, config_path: nil, image_path: nil, os_family: "Redhat">]

Should we also delete the Centos Stream mirror and use that in place of the Centos one we are switching to? I see Stream 9 and Stream are both in there?

2 CentOS Stream http://mirror.centos.org/centos/$major-stream/BaseOS/$arch/os 2024-07-19 15:57:37.289 3 CentOS Stream 9 mirror http://mirror.stream.centos.org/$major-stream/BaseOS/$arch/os 2024-07-19 15:57:37.314

Deletion is something we usually don't do. Users may have modified them to point to some internal link. That's a can of worms we prefer to keep closed

chris1984

@ekohl should I update these as well or just keep them since they just relate to tests:

foreman/test/factories/medium.rb

Line 11 in e80d555

path { 'http://mirror.centos.org/centos/$major/os/x86_64' }

I looked through everything in VSCode and don't see anything except for test fixtures, so will make the migration and push it to your branch and wait to hear back from you on the test fixtures and tests.

I tried pushing to your branch to add the migration and I am getting this:

[vagrant@toledodevel foreman]$ git push ewoud 37606-drop-old-installation-media

I tried pushing to your branch to add the migration and I am getting this:

In GitHub you can (don't have to) allow maintainers to push to your PRs. I have that enabled, but since you're not a maintainer and I didn't grant you explicit permissions you get a permission denied.

That's why I suggested to submit a PR against my fork or open a fresh PR. If you'd like to finish the whole effort then I think the latter is easier.

chris1984

@ShimShtein I helped get the migration in, it looks fine to me. I checked all the areas and other than test fixtures/tests we have covered all our bases. Let me know if this looks good or if you want me to try and update the tests.

Ewoud wanted to get this in before 3.12.

Rebased and squashed. I also expanded the commit message a bit to better describe what's going on.

This old CentOS mirror is still available for older CentOS versions, so can we keep both CentOS Stream and CentOS media's, since 8-stream content still exists on old mirrors?

It's not: mirror.centos.org no longer has any DNS records and the whole infrastructure has been retired. And I don't want to set something up pointing to vault.centos.org.

Fair enough, upon checking, I discovered 8-stream has only a readme which states "This directory (and version of CentOS) is deprecated.". So, we're fine with the current approach since 8-stream is already EOL

ekohl · 2024-10-22T12:26:38Z

Rebased and fixed -Stream to -stream.

Along with this media, should we consider updating all other CentOS mirrors which we are removing in this migration, such as CentOS 7 mirror and CentOS Stream?

It doesn't remove old media because users may have reused that and pointed it to vault.centos.org.

I suppose users could have introduced one named CentOS mirror which may conflict. I'm not sure what's best here.

How about search by URL and then removing those:

Medium.unscoped.where(url: "http://mirror.centos.org/centos/$major/os/$arch")

I don't like to surprise people and manage the data too much. I think I'll go with error handling where it ignores the rename if CentOS mirror already exists and add an upgrade warning to the release notes.

Confusingly enough, the name is not a unique column so the DB allows multiple entries with the same name. I've come up with a solution that I isn't very pretty, but probably reliable.

I'd appreciate your thoughts on it.

The new migration logic makes sense to me.
