Leo,

thanks for helping!

I'm also involving guix-devel since probably this issue must escalate
:-)

I think my specific problem is caused by the "Gateway Timeout" error
from ci.guix.info, see below for details

not explicitly but my (user) guix accepts it by default, I was able to
install other packages with no problem, also tried again some minutes
ago and succeeded installing gnumeric

this also means that my problem installing ungoogled-chromium substitute
does not depend from my X.509 problem shown below (subsitutes are
installed via https://ci.guix.info and I'm able to install them)

still, if I try to install ungoogled-chromium on my machine, it starts
building:

--8<---------------cut here---------------start------------->8---
$ guix package -i ungoogled-chromium

now, guix weather tell me this:

actually all https://ci.guix.info/ returns 504 "Gateway Time-out":
AFAIU this mean I'm not able to install that package (possibly others)
for some problem in the CDN

ouch no :-S (I'm on foreign distro)

I've installed nss-certs (and configured my env) and now "guix weather"
does not report the above error

wow: I don't have so much space in /tmp so I have to find an alternative
:-) (i.e. grow my volume, LVM unfortunately [1])

the builder! guix-daemon is The Builder!

thanks Leo: I read that once in the manual but missed it yesterday when
I needed it :-S

in my case (I'm on Debian with systemd) I have to add an "Environment="
parameter in /etc/systemd/system/guix-daemon.service, reload the systemd
file and restart the service

kudos
Giovanni


[1] because LVM is still not fully supported by Guix

I can reproduce here (on GuixSD) and like Giovanni I am unable to use

Yes.  I can still access it without problems with a browser.  I can also
access https://berlin.guixsd.org just fine.

Curl gives me the same kind of error, though:

Summary: A Cuirass API is failing, but substitutes are available.  The
CDN is not the problem.  I'll explain more below.

The 504 error comes from berlin, not the CDN.  If you access
berlin.guixsd.org directly when the 504 occurs, I think you'll see a 504
from there, too.  The CDN is merely forwarding you the 504 it got from
berlin.  I've observed this behavior multiple times in the past.  The
next time this happens, try viewing the offending location via berlin
directly in your browser:

https://berlin.guixsd.org/api/queue?nr=1000

I think you'll find that berlin, not the CDN, returns the 504 error.  To
understand why berlin.guixsd.org returns a 504, we would need someone to
investigate more on the server side.  I don't know if anyone understands
why this happens; I don't have access to investigate berlin, myself.

In any case, the 504 for the /api/queue path doesn't imply that
substitutes are unavailable.  Indeed, your "guix weather" output states
that the 1 substitute you were looking for was in fact available.  How
can this be?  Well, both Cuirass and "guix publish" are served through a
front-end NGINX web server, which confuses matters a little.  The name
berlin.guixsd.org resolves to that NGINX web server.  That NGINX web
server forwards requests to their appropriate destination ("guix
publish" or Cuirass) depending on the path.  Substitutes are served from
"guix publish" via one set of paths (e.g., /nar/gzip/<store-item>), and
Cuirass resources are served from Cuirass via a different set of paths
(e.g., "/api/queue").  It's possible for a Cuirass path to fail even
though the "guix publish" paths are working just fine.  This is because
"guix publish" and Cuirass are not the same thing, even though they are
served via the same domain name.

What I'm trying to say is that the 504 doesn't mean substitutes are
unavailable.  However, it does suggest a problem with Cuirass or its
dependencies.  When you run commands that fetch substitutes, like "guix
build" and "guix install," you will probably find that the substitution
is not failing.  If that isn't the case, please let us know.

I think the problem is not specific to 'ungoogled-chromium', because I
can reproduce it on the manifest containing all the packages I am using:

OK I got it, actually I didn't check https://berlin.guixsd.org/ whan I
got that error

the "504 Gateway Time-out" is coming from https://berlin.guixsd.org/,
**but** _sometimes_ the error goes away

I mean: if I try to reach https://berlin.guixsd.org/ or
https://ci.guix.info/ and periodically reload the page, sometimes I get
504 error and sometimes not

in particular, it _seems_ to me that the gateway time-out is triggered
by a visit to https://ci.guix.info/api/queue?nr=1000

I mean: if I reach https://berlin.guixsd.org/ or https://ci.guix.info/
and I get a proper response (not 504) I can subsequently reload the page
and clean the cache and always get a proper response; after I try to
visit https://ci.guix.info/api/queue?nr=1000 in my browser and then try
to visit https://ci.guix.info/ or https://berlin.guixsd.org/ I
systematically get a 504

OK, sorry for the confusion I made: it's not CDN related

nevertheless it seems to me we have a problem with our infrastructure

OK, so my problem getting ungoogled-chromium installed is not related to
the 504 gateway timeout from the web API

unfortunately I'm still having problems installing it since my client
does not download the substitute but starts building the derivation:

--8<---------------cut here---------------start------------->8---

...and I still can't understand why

There is no such derivation on the server at berlin.guixsd.org.

ouch, sorry! I thought "guix weather" [1] is telling me the contrary

OK there are plenty of it

I still have to learn how to find a guix commit giving me one of those
specific derivations... or just check if one specific commit provides
one of those

Thanks!

No need to apologize.  I was curious as to what’s going on here, so I
checked right on berlin.guixsd.org to see if the file exists at all.

I don’t know why the derivation you get isn’t yet available on berlin.
It’s possible that there hasn’t been an evaluation corresponding to your
commit.

You generally can’t do that.  You can’t compute the commit from only a
derivation file name.

I guess that ‘guix weather’ checks the presence of substitutes for a
current derivation of a package definition, so if in the same
environment ‘guix weather’ tells that a substitute is available and
‘guix package’ doesn't fetch it, it sounds fishy no?

Thanks.

Yes.  I cannot see the derivation in question, though, so I don’t
understand why “guix weather” would claim that a substitute exists.

I haven’t begun investigating this yet.  I’m probably overlooking
something obvious.

do you think I should file a bug report or should I wait for more
investigation in this list?

If this is not explained in the manual could you send a patch to include

The service file already includes an “Environment” line.

Also, this 'Environment=' parameter is a feature of systemd services [0]
and applicable to any use of systemd. I don't think the Guix manual
needs to include specific examples of how to set environment variables
in third-party service managers.

[0] See the manual page systemd.service(5) or view it online:

Let's confirm the issue by reproducing it, and then open a bug report.
The possible issue here is that berlin reported a substitute was
available, even though the substitute isn't actually available.  Right?

If you could provide the following information, I can try to reproduce
it for you:

- The output of 'guix describe'.
- The manifest file you used in your 'guix weather' command.

Thank you,

OK, thanks!

AFAIU the issue is "guix weather" reporting on the availability related
to current master and not of user commit: am I wrong?

a little (digression

  anyway even if that is not the issue, users should have some way to
  check if a substitute is available for their current commit, so they
  can decide if they are willing to locally build or not.
    
  also, it would be useful if "guix package -i/-u" allowed users to
  choose to fail (via a flag or a CLI prompt) in case a substitute is
  not available; AFAIU "Substitution failure" [1] works when a
  substitute *is available* but download fails (and we have "--fallback"
  just in case), but there is non way to fail in case substitute in not
  available.
    
  in my specific case with ungoogled-chromium, it took about 8 hours on
  a 8 cores + 16GB RAM machine (although heavily used) to reach 75% of
  the build process... and finally I had to cancel the build since the
  machine load reached 40 (since other "heavy" processes started via
  cronjobs).)

anyway: back to the issue

I'm not sure.  That would explain the issue you saw.  I haven't checked
the code.  Maybe you could take a peek?  If "guix weather" is using
master branch and ignoring the current channel configuration, it seems
like it might be unintended behavior.

I agree it would be nice if one could control the behavior more easily.
However, someone needs to put in the time to design and implement the
solution.  So far, I think people with time and energy have chosen
instead to focus on improving substitute availability, in the hopes that
it will prove more useful in the long term.

Would you be interesting in working on it?  I have sometimes wanted a
feature like that, but I do believe substitute availability will help
more in the long term.

Excellent - thank you.  I think I missed this in your emails earlier.

I have attempted to reproduce the issue using that information.  When I
ran "guix pull" to use the same version of Guix you were using
(a4fc80254a53b46b33f138d1009ddd044b8cb6be) and then ran "guix weather",
I saw the same output as you (i.e., ci.guix.info reported that the
substitute was available).  However, when I ran...

  guix package \
       --substitute-urls=https://ci.guix.info \
       -p /tmp/test-profile \
       -m /tmp/manifest.scm

...Guix began downloading chromium from ci.guix.info.  The contents of
/tmp/manifest.scm is the same manifest you provided.  So, unfortunately
this means I wasn't able to reproduce the issue you experienced.
Everything seems to be working correctly on my end.

I'm afraid I'm out of time at the moment - I have to go.  But if you
could the check "guix weather" source code to find out if it respects
the current channels, that would be great.  I'll try to get around to it
if you don't beat me to it.

I'll try to understand guix weather code (guix/guix/scripts/weather.scm)
but I'm pretty new to Guile and Guix so it will be a long study for me

...so sorry, but for now do not count on me for a timely report on this

yes I'm aware of this and I find this is not a priority for Guix,
improving substitutes availability is

yes but for me "it's a long way to the top if you (me) wanna

could you please report here the exact substitute derivation you got?

on Monday Ricardo told us:

There is already a bug created about this topic: "do not attempt to
build a package known to be broken":

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=33737

It seams like the discussion faded out because the daemon is not yet
ready for this, and there were some discussions about corner cases like
indeterministic build failures.

Another related topic discussed before (I'm not sure if there is a
ticket for this) is to collect build resource consumption (wall-time,
cpu-time, memory-usage, ...) and store it in a local or even
global database. With that data available you could at least roughly
calculate the cost of compilation and if you want to put that effort in
(or to plan your heavy compilation say overnight).

I found with a huge profile there is always some dependency failing.
And it is not clear which leaf packages to exclude to "just" update the
rest of your profile. This could be automated. I would like to see that
feature.

Though on the other hand as you said, everyone's resources are limited
and we tend to look at the packages and getting them fixed.

[-- Attachment #1.1: Type: text/plain, Size: 7715 bytes --]

Hi Giovanni,

I think I may have been confused when I sent my last email.  I saw Guix
downloading the source and mistakenly assumed that it was downloading a
substitute for Chromium.  I looked at the log more closely, and I think
now I was actually able to reproduce your issue.

Using the information you provided, I ran this command:

guix package --substitute-urls=https://ci.guix.info -p /tmp/test-profile -m /tmp/manifest.scm 2>&1 | tee /tmp/package-install.log

I've attached the gzipped log to this email, for your reference.  In it,
you can find messages like the following:

--8<---------------cut here---------------start------------->8---
$ grep ungoogled-chromium /tmp/package-install.log 
downloading from https://ci.guix.info/nar/gzip/g92nls9b9ggnhgmdd9ycmcws38z9aw43-ungoogled-chromium-a58db88-checkout...

--8<---------------cut here---------------end--------------->8---

As you can see, it seems Guix actually did build ungoogled-chromium (the
line "building
/gnu/store/4mvzzx2jmr4r4p2kx0hcvwr9s9lvx0gd-ungoogled-chromium-72.0.3626.109.drv"
is followed by what appears to be many lines of compilation output).

Ultimately, what gets installed into the profile is:

  /gnu/store/za5b7s35jskvvvlv0favqy4as1cfk332-ungoogled-chromium-72.0.3626.109

which is the output of

  /gnu/store/r0jfc6lfakh0mg764kyxzzmlf21b3d7c-ungoogled-chromium-72.0.3626.109.drv

which itself is a graft derivation.  This graft derivation appears to
have the following derivation as an input:

  /gnu/store/4mvzzx2jmr4r4p2kx0hcvwr9s9lvx0gd-ungoogled-chromium-72.0.3626.109.drv

which is the derivation that builds the ungrafted ungoogled-chromium.
This makes sense, since the graft derivation needs to modify the
original.

A few minutes ago, I ran "guix weather" again.  It says 1 substitute
(which one, I wonder?) is available:

--8<---------------cut here---------------start------------->8---
$ guix weather -m /tmp/manifest.scm 
computing 1 package derivations for x86_64-linux...
looking for 1 store items on https://ci.guix.info...

  612.7 requests per second
  'https://ci.guix.info/api/queue?nr=1000' returned 504 ("Gateway Time-out")
--8<---------------cut here---------------end--------------->8---

I then tried to download substitutes manually.  However, when I try to
download the grafted and ungrafted versions, I get a 404.  Here's a
summary of these derivations, based on what I observed:

This graft derivation for ungoogled-chromium...

  curl -v -o /dev/null https://ci.guix.info/nar/gzip/2xnx8nglb8dyjvkq0zra17baxkyic721-ungoogled-chromium-72.0.3626.109

...I get a 404 from ci.guix.info.

I expected to get a 200 in at least one of those cases, since "guix
weather" said that 1 substitute was available.  I don't really know
what's going on here, but it seems strange.  I guess we need to
investigate more.

It would be interesting to know if "guix weather" honors the current
channel configuration, or if it always checks master.  If it always
checks master, then that could explain what we're seeing.  Anyway, it
seems like it might be time for a bug report.  Could you summarize the
issue and open one?

I don't know about berlin, but hydra.gnu.org has *never* successfully
built ungoogled-chromium.  So far, it has made 3 attempts on
x86_64-linux and 5 attempts on i686-linux:

  https://hydra.gnu.org/build/3387889 (x86_64-linux)
  https://hydra.gnu.org/build/3381436 (x86_64-linux)
  https://hydra.gnu.org/build/3380876 (x86_64-linux)
  https://hydra.gnu.org/build/3386821 (i686-linux)
  https://hydra.gnu.org/build/3385227 (i686-linux)
  https://hydra.gnu.org/build/3381453 (i686-linux)
  https://hydra.gnu.org/build/3380895 (i686-linux)
  https://hydra.gnu.org/build/3379818 (i686-linux)

If the same is true on berlin.guixsd.org, that would explain the lack of
binary substitutes.

Berlin did build it, soon after the package was first added. I used the
substitute on my machine which lacks the capacity build the package.
