= Summary =

Launchpad should know which mirrors are set as official country mirrors (eg. gb.archive.ubuntu.com), so that we can track these easily on mirror listings.

This branch also includes a database change (patch-2207-20-0.sql) which adds a official_country_mirror column to distributionmirror. It also includes two constraints to ensure that there can not be more than one (archive|releases) mirror per country.

New mirrors have been added to current(-dev).sql for testing purposes too.

A mirror should only be eligible for country mirror status when:

1) it has been reviewed and set as an official mirror by an admin,
2) it has been probed for integrity,
3) it has an HTTP URL set.
4) there is no country mirror for that mirror type in the country.

Checks have been added to the code to ensure that these conditions are met.

Hello Jonathan,

Thanks for this patch -- I can see how this would be useful.

I don't have any serious issues with the database patch -- the uniqueness constraint looks correct to me. My main concern is that using the word 'official' to describe this new concept will create confusion with the already existing concept of 'official mirror'. Would 'primary_mirror' make sense?

Other than that, the db patch looks good to me.

Why are we limiting things to one official country mirror per country? Is there a technical issue we need to ensure doesn't happen, or is this an arbitrary choice made by us or the mirror maintainers?

Patch number is patch-2207-23-0.sql. Its good to land if you can confirm that the UNIQUE constraints are actually desirable.

One thing that needs changing - You should use 'IS TRUE' and 'IS FALSE' rather than '= TRUE' or '= FALSE'. = and IS give different results in SQL's three valued boolean arithmetic which can confuse the query planner since it isn't as smart as you.

Morning Jonathan,

Country mirrors are official mirrors whose FQDNs have been CNAME'ed to a $CC.[archive,releases].ubuntu.com domain. This is why we refer to them as official country mirrors.

Stuart,

We're limited to one country mirror because it's not possible to load balance between two different Ubuntu archives mirrors because of limitations with the apt-get software unless the two mirrors are in perfect sync.

Also I believe, the plan is to, hopefully, auto-generate our CNAME DNS records of country mirrors using the ones specified in LP's DB by admins (with this patch). And it's not possible to have multiple CNAME records to a FQDN.

Hi Jonothan, thanks for yet another long-awaited feature :)

I'd really like to get Curtis to look at this one, although I've got a few comments.

The first question that came to my mind was, why is this another separate form (currently there is "Change details", "Review", and now "Set/Unset as country mirror".

I personally wonder whether the 'Review' form could accommodate this (perhaps renamed with something that implied official and/or country-mirror status?), so that both items could be presented and dealt with there on the one form. This would also alleviate the need for the changing menu item name ('Set/Unset'). But Curtis might have other ideas.

Also, when editing the mirror after setting it as a country mirror, the validation is great (for country/content-type), but afaik it shouldn't redirect back to the +index page, but instead +country-mirror form itself?

IRC snippet:

<noodles775> jpds: what's the reasoning behind not doing this as an admin-only field displayed on the normal edit form?
<jpds> noodles775: Do you mean the +review form?
<noodles775> jpds: no, I meant the +edit form (but i'm logged in as an admin, maybe that's not presented for mirror-admins...). Checking now.
<jpds> noodles775: I wanted to make it a little obvious by having the separate button for it.
<jpds> noodles775: And mirror registrants shouldn't be able to see the checkbox themselves.

Sorry, that's very unclear (and incorrect). What I meant was, once you have set a mirror as a country mirror, when you then go back and change the details (on the +edit page), the validation there is great for country/content-type, but when that validation is triggered, the page should be redirected back to the +edit form, not back to the +index, as there could be other things that were updated by the user?

Hi Johnathan.

Thanks for undertaking this large effort.

I reviewed the code and the UI. There is a lot that needs fixing, but I
can help with some of it.

Starting with the UI.

I like your change to move country_dns_mirror to +edit, but per your original
concern, it is not obvious that the mirror admin uses this page to change the
state. We strive to move edit and view links into the page where the
information is presented so that it is clear to the user that he can change
what he is reading. This is a simple one-line addition to the template.

However, the addition of a new portlet makes the layout worse. This page
has known issues because it was one of the first to be changed for 3.0,
but it was not updated as 3.0 style evolved. The registration and status
information are not in their correct places: the registering slot and the
Mirror information portlet. If they were, the addition of the new field
would be easy and obvious. I tinkered with the template to fix the layout
and I have a diff that you can apply to your branch to get these changes.
In the fixed layout, the official country dns status appears higher on
the page and I think that is good.

    Suggested layout: http://people.canonical.com/~curtis/mirror.png
    Diff to revise layout: http://people.canonical.com/~curtis/mirror.diff

I do not like the info notifications. They make me worry that my other
changes were not accepted. Since the form did what I asked it to, there
is no need to take such an extraordinary measure. I think they should be
removed.

I pondered the addition of the star to the mirrors list. Your approach is
just like badges that are applied to bugs, so I think it is correct. I think
my misgivings are from my unfamiliarity with the star as an icon. I did
learn it was official when I placed my mouse over it. I think we can leave
it as is.

BTW. There is a problem with this merge proposal. It must be merged into
db-devel since the schema changes are incompatible with lpnet/edge. If you
had proposed the merge with db-devel you would have seen that your db
patch conflicts. You need to rename it and update it as suggested by Stuart
before this can be tested properly.

323+=== Country DNS mirrors ===
324+
325+Country DNS mirrors are official mirrors whose FQDN have been CNAME'd for
326+domain records such as gb.archive.ubuntu.com. They are highly reliable and set
327+during installation, depending on which country the user specified they were
328+in.
329+
330+Mirror listing administrators are the ones with the authority to set mirrors as
331+country mirrors.

369+ ...
370+ LookupError: name 'field.country_dns_mirror'
371+
372+Mirror registrants may not make changes to country DNS mirrors settings:
373+
374+ >>> browser_mirror_registrant = setupBrowser(
375+ ... auth='Basic test@canonical.com:test')
376+ >>> browser_mirror_registrant.open(

409+
410+We can however set a country archive mirror for another country in the
411+mean-time, just fine:
412+
413+ >>> browser = setupBrowser(auth='Basic karl@canonical.com:test')

422+ <div class="informational message">The mirror Technische Universität
423+ Dresden has been set as the country DNS mirror for Germany.</div>
424+
425+Setting releases mirrors as country releases mirrors should not conflict with
426+country archive mirrors settings:
427+
428+ >>> browser = setupBrowser(auth='Basic karl@canonical.com:test')
429+ >>> browser.open(
430+ ... 'https://launchpad.dev/ubuntu/+mirror/mirror.mawson.antarctica.org-releases')

436+ >>> print find_tags_by_class(browser.contents, 'informational message')[0]
437+ <div class="informational message">The mirror Mawson Station has been set
438+ as the country DNS mirror for Antarctica.</div>
439+
440+Once a mirror has been set as a country mirror, it's content type or country
441+may not be changed:
442+
443+ >>> browser = setupBrowser(auth='Basic karl@canonical.com:test')
