Hello Chris, > + guix_substitute_urls="https://ci.guix.gnu.org https://bayfront.guix.gnu.org" What is the rationale behind adding a new substitution server? I feel like having two substitute servers will make things more complex in term of maintenance. Having both servers compute the same set of substitutes is also not great from an energetic and resource saving point of view. Thanks, Mathieu

Hey, I should have probably written a cover letter, but this patch is me starting to try and work out the changes involved in getting substitutes from bayfront to general Guix users, but the discussion has been happening in this thread [1]. 1: https://lists.gnu.org/archive/html/guix-devel/2021-05/msg00241.html Bayfront has been around for a while, and has been serving substitutes, although I'm not sure it's provided much value to users in that time. I hope that can change with switching to using the Guix Build Coordinator though, that happened around a month ago, and it's slowly building things and catching up. I guess there's a greater need to maintain it if starts getting used by more users, so I do think the maintenance involved is something to consider. Personally, I see the arguments for having multiple substitute servers getting stronger over time. Multiple independent substitute servers would provide more reliability than a single source, as well as enabling things like K of N trust in substitutes [2]. 2: https://lists.gnu.org/archive/html/guix-devel/2020-06/msg00179.html In terms of energy and resources, currently there are 5 machines in use, most of which were mostly idle before being put to use building things for substitutes. While having them build things does use more power than having them idle, I think the value provided, even if that's providing exactly the same bytes as ci.guix.gnu.org, is worth the cost, for the reasons I give above. Thanks, Chris

Christopher Baines <mail <at> cbaines.net> writes: > Is there still a path to bring some of these benefits to users, and if > so, what things need doing? It's been a few weeks now, so to summarise, I think only one path emerged, and that is to get substitutes from bayfront to users. Bayfront was already running the Guix Build Coordinator (although only for the last month), and it's now caught up to the point where I'm seeing similar or better substitute availability percentages for x86_64-linux (and powerpc64le-linux) when compared to ci.guix.gnu.org. It's also building i686-linux and aarch64-linux things, but they're still catching up. Obviously just having the substitutes doesn't magically get them to users, so I've started looking in to the changes to start making that happen. Adding the signing key and changing the defaults in a few places seems like a good step forward [1]. 1: https://issues.guix.gnu.org/48435 I want to push on with this within the next couple of weeks, mostly so I can shift focus to Outreachy and the security related tooling work, but also because I still think this will be a good step forward in terms of substitute availability for users. It's been over a year now since implementation started, so it would be good to actually make a positive difference. There's a few issues still on my mind. Even though the substitute availability percentages are good when compared to ci.guix.gnu.org, as bayfront has much less compute power connected, it might not keep up as well when big sets of changes are merged. I think that's just an argument for using the build coordinator on berlin and the connected machines though. The other thing in comparison to ci.guix.gnu.org is that bayfront only has ~4TB of storage rather than ~37TB, and given that currently none of the generated nars are deleted, that will need thinking about in a few months to avoid running out of space. I've had some plans around this for a while [1], but they still require implementing. 1: https://lists.gnu.org/archive/html/guix-devel/2021-02/msg00104.html Apart from merging the changes in [1], I guess a blog post might be useful. Have I missed anything? Chris

I’m fine with distributing an extra signing key alongside that of ci.guix.gnu.org. I’m unsure about having two substitute URLs by default since it adds a bit of overhead, though that overhead is only upon cache misses (I have that setup on my laptop actually). It’s also a one-way change: people are likely to keep the defaults “forever”. So we can’t just “experiment” and change our mind later. That means we should at least have a DNS entry that’s not tied to a particular machine, like ci2.guix.gnu.org or whatever. WDYT? Now, what would be nice is to have a second build farm with the K-out-of-N policy you mention in mind. > There's a few issues still on my mind.

As much as I’d have preferred a single solution in this area, fueling competition between the Coordinator and Cuirass and their access to official infrastructure doesn’t seem like a viable path to me. I think the primary value in having a second build farm would be reproducibility and doing away with the single point of failure. Overall substitute coverage probably wouldn’t change much. I agree with Mathieu that maintaining it has a cost, but maybe we can try. I realize I’m asking questions rather than providing answers, which may be because I don’t see a clear path ahead. :-) Thanks! Ludo’.

Great. > I’m unsure about having two substitute URLs by default since it adds a > bit of overhead, though that overhead is only upon cache misses (I have > that setup on my laptop actually). All of this work has been built on the assumption that it's possible to do better in providing substitutes, and anecdotally from the data I've seen over the last year, that should be possible, even with the limited hardware (compared to ci.guix.gnu.org) connected to bayfront. So yes, that's a valid concern, but if all the addition of bayfront does is make users wait a little longer because of cache misses, it's a sign that the whole endeavour is not working out. > It’s also a one-way change: people are likely to keep the defaults > “forever”.

That sounds sensible. On the specific name, given this is just about substitutes, and at least in my opinion has nothing to do with continuous integration, maybe picking just another word would avoid thinking too much, it could be bordeaux, or hippo, or anything really. As you say, stability and not being tied to a particular machine is the important thing.

For instance, the evaluation speed, the failed evaluation count, the average evaluation builds completion time, the availability of the connected build machines between other things. Deploying a solution that builds substitutes is fine, but as soon as it is deployed and accessible to all Guix users, the system administrators will have to monitor it and maintain it in the long run. Having two heterogeneous build infrastructures on two sets of machines, providing different metrics will make the update and maintenance of those machines harder. I hear your point about K-out-of-N policy and it also makes sense to me. However, we should maybe consider doing it using two similar infrastructures. Thanks, Mathieu

There are more changes that can be made in the future, but these changes seem like a good start. * config-daemon.ac (guix_substitute_urls): Add https://bordeaux.guix.gnu.org. * guix/scripts/substitute.scm (%default-substitute-urls): Add http://bordeaux.guix.gnu.org. * guix/store.scm (%default-substitute-urls): Add bordeaux.guix.gnu.org. * doc/guix.texi: Adjust accordingly. * doc/contributing.texi: Adjust accordingly. --- config-daemon.ac | 2 +- doc/contributing.texi | 8 +- doc/guix.texi | 142 +++++++++++++++++++----------------- guix/scripts/substitute.scm | 3 +- guix/store.scm | 3 +- 5 files changed, 86 insertions(+), 72 deletions(-) diff --git a/config-daemon.ac b/config-daemon.ac index 85caee269b..5ddc740600 100644 --- a/config-daemon.ac +++ b/config-daemon.ac @@ -117,7 +117,7 @@ if test "x$guix_build_daemon" = "xyes"; then dnl Determine the appropriate default list of substitute URLs (GnuTLS dnl is required so we can default to 'https'.) - guix_substitute_urls="https://ci.guix.gnu.org" + guix_substitute_urls="https://ci.guix.gnu.org https://bordeaux.guix.gnu.org" AC_MSG_CHECKING([for default substitute URLs]) AC_MSG_RESULT([$guix_substitute_urls]) diff --git a/doc/contributing.texi b/doc/contributing.texi index d67e632520..1086bb9fd4 100644 --- a/doc/contributing.texi +++ b/doc/contributing.texi @@ -376,12 +376,12 @@ Once your package builds correctly, please send us a patch (@pxref{Submitting Patches}).
