Testing needed for lzip substitutes!

Testing needed for lzip substitutes!

[Ludovic Courtès]

Hello Guix!

I’ve set up ‘guix publish’ with both gzip and lzip substitutes at
<https://qualif.ci.guix.gnu.org>, in a setting similar to what we’ll
eventually deploy on ci.guix.gnu.org if everything goes well (there’s no
proper TLS certificate but it doesn’t matter for ‘guix substitute’).

Please try to fetch substitutes from there:

  --substitute-urls=https://qualif.ci.guix.gnu.org

If you’re running an “old” guix-daemon, you should be getting gzipped
substitutes; otherwise you should be getting lzipped substitutes (check
the URLs for /gzip or /lzip.)

Note that initially many substitutes will be missing because they need
to be “baked”; when that happens, be patient, and try again 5mn later.

‘guix publish’ is running with “-C gzip:5 -C lzip:9” mostly to save CPU
time, so don’t use it as an lzip vs. gzip benchmark.

Thanks,
Ludo’.

I've switched to it yesterday and since then it seems I have to compile
everything myself :(
Subversion, git, boost, to name a few.

I do get the source from qualif.ci.guix.gnu.org though:

--8<---------------cut here---------------start------------->8---
downloading from https://qualif.ci.guix.gnu.org/nar/z4yv0m8wqfqgpgqalgx1dlqylq6rwqyg-git-2.21.0.tar.xz...
--8<---------------cut here---------------end--------------->8---

Is this expected?  If not, any idea how to investigate?

Ping! :)

I haven't run built packages much recently, but any idea what could be
wrong?  (Assuming there is anything wrong and it's not just me.)

I’m not sure what problem you’re referring to.  What I can say is that
substitutes made starting from today are available as lzip.  So for
example, if you run ‘guix pull’, the substitutes corresponding to the
various derivations of Guix (‘guix-cli’, ‘guix-base-packages’, etc.)
are available as lzip.

HTH!

Hmmm, actually, why would it be a matter of age?  I think it's only a
matter of context, and someone browsing the archive years later will not
mind if a reply was sent 1 day or 1 week later.  All that matters is the
full thread.  In my opinion a single email
is useless when not in the context of the entire thread.
So I believe that it makes more sense for email clients to use
threading than not.

Or maybe that's not what you meant :p

So I've tried with both qualif and ci, and qualif did not publish any
substitutes for me.  It works on ci.guix.gnu.org though, and I get
lzipped substitutes!  Hooray!

What I meant is that it’s easier for me (and for others I believe) if
there’s a bit of context.  Gnus doesn’t display the whole thread by
default, so I have to explicitly ask it to display it, etc.

In a way, it’s a MUA issue, and mu4e-conversation seems to be a great
solution to that problem, but not everyone uses it yet.  ;-)

Yay!  qualif is gone now.

Thanks,

I will in the future, but deep inside me I'm not the conservative kind
and I'd rather encourage the community to "future-up" :p
It's not a very sophisticated feature after all :D

By the way I'm using Notmuch these days and it's even better at
threading in my opinion (mu4e-conversation is a bit hackish :p).

It's not always a MUA issue, think of people reading web-based ML acrchives

The web interface Guix uses shows links to the other emails in the
thread, so I think it's OK in this case.
And it's still an interface issue :p
