I fixed it with a substitute* instead, and also applied another upstream
fix in commit 5f37d7e38e.

Thanks for the report!

Assuming you run Emacs in that foo profile and don't see the font,
that's probably because XDG_DATA_DIRS is unset in that other profile.
glib is one of the package setting that variable.

I'm merging this bug with 22138, which would fix the root cause.

I had no other problems until today.

Today, I installed Ubuntu 20.04 in a VM for testing. It is exhibiting
similar problems. In the Ubuntu case, it is not hanging. Instead, the
screen goes black and I cannot get it back; but I can still SSH into
the Ubuntu machine.

I guess it's another Gnome bug that will be abandoned in 6 months.

bug#43802: Knot: Linker runs very slowly and crashes during build

[Simon South]

Building Knot 3.0.0 using "guix build knot" consistently appears to hang
for me when it gets to this point during the linking stage:

CCLD knsec3hash
  ar: `u' modifier ignored since `D' is the default (see `U')
CCLD kdig
CCLD khost

While it sits here the compiler is tying up 100% of a single CPU
core. On my ROCK64 with 4 GB of RAM, it eventually crashes with an
internal error:

  gcc: internal compiler error: Killed (program cc1)
  Please submit a full bug report,
  with preprocessed source if appropriate.
  See  for instructions.
  make[3]: *** [Makefile:5381: libzscanner/la-scanner.lo] Error 1
  make[3]: Leaving directory '/tmp/guix-build-knot-3.0.0.drv-0/knot-3.0.0/src'

dmesg shows the compiler was killed for running out of memory:

  cc1 invoked oom-killer: gfp_mask=0x100cca(GFP_HIGHUSER_MOVABLE), order=0, 
oom_score_adj=0
  CPU: 2 PID: 22340 Comm: cc1 Not tainted 5.8.11-gnu #1

oom_score_adj:0
  oom_reaper: reaped process 22340 (cc1), now anon-rss:0kB, file-rss:0kB, 
shmem-rss:0kB

On my x86_64 machine the build eventually completes (that machine has
much more memory), but there is the same, weirdly long delay during
linking while the compiler runs.

I see no such delay however when I build the code "manually", using
"guix environment --pure knot" or even "guix environment --no-grafts
--container knot" as the manual suggests. The build then completes
quickly and successfully on either machine; the problem appears to
happen only when guix-daemon is involved.

Is there a known issue that can cause the linker to consume orders of
magnitude more resources when run by the Guix build process?

Apart from rebuilding gcc with debugging symbols (which seems to make
Guix want to rebuild every other package in the system as well) and
trying to understand what the compiler is doing, how might I go about
diagnosing this?

I think a bold, but definitive approach at fixing this problem would be
to never use known environment variables in Guix search paths
specifications.

Instead, we should introduce custom Guix-specific flavors of the same
variables, e.g. GUIX_GI_TYPELIB_PATH.  That's more work (need to write
and maintain patches that add those Guix-specific variables along their
regular flavor), but that'd mean we can set all the variables we want
not worrying about breaking a foreign distribution.

What do you think?

As with other things Guix, mix and match of ad-hoc package management
(e.g., Emacs' native package management) and Guix can cause conflicts.
There is not always a clear solution to these problems.

I don't use Emacs' native package management facility, but if it clashes
with our own use of EMACSLOADPATH and site-start.el, it could be work
looking into (as a fresh bug).

I'll close this one for now.

Thanks!

bug#43243: emacs-elfeed-org, mapc: Symbol’s function definition is void

Hello,

I resolved this issue: (obviously) It was my fault, please see below.

zimoun  writes:

[...]

This sentence slowly guided me to the solution: I still had
~/.emacs.d/elpa and after I deleted that, the initial error reported in
this bug disappeared, with another one I discovered later.

AFAIU the error was triggered by the fact that my Emacs (on foreign
distro) was still loading some old code from ~/.emacs.d/elpa, installed
using use-package (mixed with Debian packages in some case) before I
migrated to Guix Emacs.

All this confusion comes from the fact that before upgrading to 27.1 I
was using the same version (26.3) installed from Debian and then
migrated to Guix: this way, apart some strange warning I fully
understand only today, my Emacs Guix was running fine as before.  So
when I upgraded I misintepreted the situation as coming from some
problem of elfeed-org with 27.1.

Probably we should add a warning in our manual to avoid other users on
foreign distros will get in similar situations: I'd like to help but I'm
not sure I'll be able to find the right words.

Simon: about my strange use of

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

 (unless (require 'guix-emacs nil 'noerror)
  (use-package

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

I think is a tengent here, so if you agree I'd discuss it on guix-users
(IMHO is OT on guix-devel).

Re. this bug, I think the situation is clear now and if you agree I'd
close it.

Thanks a lot! Emacs-Fu panda Gio'

bug#43796: Privacy policy

[Julien Lepiller]

Looks nice, but:

The GDPR is not the only legislation that applies to us. For services hosted in 
France for instance, there is a legal obligation to keep logs for at least one 
year (not sure exactly who that applies to). There could be something similar 
in Germany where berlin is located.

I think some of the wording is vague. Does "can be used to identify" mean we 
will use the IP to identify the person (is it the reason we process this data?) 
Or is it something that we could technically do, but refuse to do?

bug#43796: Privacy policy

[pelzflorian (Florian Pelz)]

IANAL but I think Guix needs a privacy policy for both its website and
the Guix software in general.

Attached is a patch for the website that also documents data use by
Guix and Guix System.  Maybe I’ve overdone some parts and probably
something important is missing.

In particular, the GDPR requires IP addresses to be deleted from logs
after a reasonable time.  I think but am not sure the current process
for nginx is to delete only when the log files become too big.  A more
suitable policy must be implemented and the users must be told about
it, I think.  See .

In general I think it is better to have an incomplete policy than to
have none.

Comments?

I can’t say why the Qt build system does this, but in other cases we
know that 'prefix causes problems because the application may end up
loading incompatible binaries leading to a crash.  That’s especially the
case on foreign distros, e.g. when the Guix-installed graphical
application loads a plugin from the system’s XDG_* directories.

I managed to capture two instances of 'transferred= #f' from my pk

Attached is a pruned version of the strace log of a command like

bug#43791: cuirass: Search queries are too slow.

[Mathieu Othacehe]

Hello,

Search queries can take a long time to complete.

This query took 658.67 seconds to complete:

--8<---cut here---start->8---
SELECT * FROM ( SELECT Builds.rowid, Builds.timestamp, Builds.starttime, 
Builds.stoptime, Builds.log, Builds.status, Builds.job_name, Builds.system, 
Builds.nix_name, Specifications.name FROM Builds INNER JOIN Evaluations ON 
Builds.evaluation = Evaluations.id INNER JOIN Specifications ON 
Evaluations.specification = Specifications.name WHERE (Builds.nix_name LIKE 
'%hurd-barebones.qcow2%') AND (0 IS NULL OR (Builds.status = 0)) AND 
('guix-master' IS NULL OR (Specifications.name = 'guix-master')) AND 
('x86_64-linux' IS NULL OR (Builds.system = 'x86_64-linux')) AND (NULL IS NULL 
OR (NULL < Builds.rowid)) AND (NULL IS NULL OR (NULL > Builds.rowid)) ORDER BY 
CASE WHEN NULL IS NULL THEN Builds.rowid ELSE -Builds.rowid END DESC LIMIT 1) 
ORDER BY rowid DESC 658.67
--8<---cut here---end--->8---

and this one:

--8<---cut here---start->8---
SELECT MIN(Builds.rowid) FROM Builds INNER JOIN Evaluations ON 
Builds.evaluation = Evaluations.id INNER JOIN Specifications ON 
Evaluations.specification = Specifications.name WHERE (Builds.nix_name LIKE 
'%ganeti%') AND (NULL IS NULL OR (Builds.status = NULL)) AND (NULL IS NULL OR 
(Specifications.name = NULL)) AND (NULL IS NULL OR (Builds.system = NULL)) 
146.70
--8<---cut here---end--->8---

took 146.70 seconds.

The naive solution of adding an index on nix_name column does not work
as it is still ignored for some reason.

According to https://www.sqlite.org/optoverview.html, starting the LIKE
search pattern with '%' prevent the index use.

However, searching for 'hurd-barebones.qcow2%' also skips the index.

Thanks,

Mathieu

bug#43564: cuirass: Contention while registering new builds.

[Mathieu Othacehe]

Hello,

> I'm trying locally to spawn database workers dedicated to registration,
> that execute the evaluation queries in a single batch. Let's see if it
> helps.

I added 4 registration dedicated database workers and removed from
registration all accesses to the store. Now the evaluation returns
objects that contain all required information.

This seem to improve the situation quite a lot. For example, those three
registrations were done simultaneously in ~200 seconds:

--8<---cut here---start->8---
2020-10-04T12:46:19 registration took 205.429772 seconds
2020-10-04T12:46:19 evaluation 17099 registered 156 new derivations
2020-10-04T12:46:19 building 156 derivations in batches of 200
2020-10-04T12:46:19 building batch of 200 derivations (0/156)
2020-10-04T12:46:19 registration took 212.892482 seconds
2020-10-04T12:46:19 evaluation 17105 registered 164 new derivations
2020-10-04T12:46:19 building 164 derivations in batches of 200
2020-10-04T12:46:19 building batch of 200 derivations (0/164)
2020-10-04T12:46:19 registration took 205.009416 seconds
2020-10-04T12:46:19 evaluation 17102 registered 160 new derivations
2020-10-04T12:46:19 building 160 derivations in batches of 200

bug#43446: EGL-Wayland

[Raghav Gururajan]

Hello Brendan!

I think you are missing 'egl-wayland'.
https://git.savannah.gnu.org/cgit/guix.git/commit/?id=8d82df1376f50bb1e32fa82e943b0f5c837658b6

Not sure if, Qt packages or Qt apps or both, requires rebuilding with 
egl-wayland as input.

Regards,
RG.

bug#43773: [PATCH] offload: Improve load normalization and configurability.

this looks like a good change to me; actually I ended up encoding the number
of cores in the "speed" field instead, which is a dirty hack around the
core problem.
