Hello,

I have a relatively recent guix version (ran guix pull yesterday) and I
can't build emacs, as libarchive, one of its dependencies, fails to build.
Here is a snippet of the error message:

Ricardo reported the same issue a while back:

  https://lists.gnu.org/archive/html/guix-devel/2015-03/msg00182.html

What platform is this on, i686?

It would be nice to see if this systematically fails.  If it is
non-deterministic, we should build it with --keep-failed until it fails
(removing successful builds with ‘guix gc -d’), collect useful info from
the build tree, and debug.

(You can also work around it by enabling substitutes since Hydra had no
problems building it.)

In my case the build fails always. I'm running guix on Fedora 23, x86_64.

I debugged this and the upstream patch
https://github.com/libarchive/libarchive/commit/b539b2e597b566fe3c4b49cb61c9eef83e5e052d
fixes the problem. You will probably want to add it to the build process.

I just realized I need to do this locally as well to fix the
compilation...:) How do I modify the build process and add the patch
to the store?

What file system is this on?

I’ve run several builds on my x86_64 GuixSD, ext4, but I’ve failed to
reproduce the test failure.

I noticed that libarchive uses ‘readdir’ calls as-is, without sorting
directory entries afterwards.  Thus, the order of directory entries is
effectively non-deterministic and may change depending on the phase of
the moon.

This has been reported at:

  https://github.com/libarchive/libarchive/issues/602

Could you add the patch that’s given at that URL to the ‘patches’ field
or libarchive’s ‘origin’ form and see if the problem shows up again,
preferably building several times in a row?

At any rate we’ll probably apply the patch.

Thanks,
Ludo’.

The test itself seems to always run in /tmp, which is tmpfs in my case. I tried
patching it to run in /var/tmp, which is ext4 (on LVM), but that failed as well.

I could reproduce the issue even outside of the guix build process.
I downloaded the tarball, extracted it and ran configure + make + make check.
The latest git version worked fine, even though the asserts in test_option_b.c
didn't change.

I built it once and it passed (note that it failed *everytime* I
wanted to build it).
Maybe a dumb question, but how do I force a rebuild of an already
built package?:)

Just list the patch in the ‘patches’ field of libarchive.  See for
instance ‘grep’ in gnu/packages/base.scm for an example.

You can’t rebuild packages because build processes are assumed to be
deterministic.  However, you can delete a build result with ‘gc -d’, as
mentioned above, and rebuild it afterwards.

So I've built the package several times and it worked every time. I don't even
think the build was failing non-deterministically, because, as the
commit message
of the patch explains, the unpatched bsdtar was trying to put things
like SELinux
contexts into the archive, which resulted in an archive with bigger size than
anticipated. And since I'm running guix on Fedora, I probably hit the
SELinux problem.

Thank you for helping out!

Cheers,

Oh, I see.  Thanks for investigating!

Now to apply the patch…

To determine how to handle the mass rebuild, I wanted to see how many
packages depend on libarchive.  However, ‘guix refresh -l’ would
underestimate that number because it ignores implicit dependencies, and
it turns out that libarchive is a dependency of CMake, which in turn is
an implicit dependency of many things.

So I thought (guix scripts graph) has the necessary infrastructure to
manipulate these graphs, including using the “bag” representation, so
why not use it.

Hence, commit 8fb5837 adds a generic (guix graph), 923d846 adds a couple
of helper procedures, and a51cbec rewrites ‘guix refresh -l’ in terms of
(guix graph).

Before the change:

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

Building the following 11 packages would ensure 18 dependent packages are rebuilt: ath9k-htc-firmware-1.4.0 totem-3.16.1 rhythmbox-3.2.1 diffoscope-34 rdup-1.1.14 nestopia-ue-1.46.2 file-roller-3.10.0 gvfs-1.24.1 claws-mail-3.13.0 zathura-cb-0.1.4 python-libarchive-c-2.1

After:

--8<---------------cut here---------------start------------->8---
$ time ./pre-inst-env guix refresh -l libarchive
Building the following 279 packages would ensure 620 dependent packages are rebuilt: python-libarchive-c-2.1 i3status-2.9 libwebsockets-1.3 vtk-6.1.0 taskwarrior-2.4.3 synergy-1.7.4 guile-ssh-0.8.0 diffoscope-34 python-tlsh-3.4.1 libpano13-2.9.19 slepc-complex-3.6.2 slepc-3.6.2 plink-1.07 apl-1.5 mumps-5.0.1 mumps-metis-5.0.1 gmsh-2.8.4 dealii-8.2.1 julia-0.3.10 c-reduce-2.3.0 gcc-4.9.3 clang-3.5.0 unionfs-fuse-0.26 unionfs-fuse-static-0.26 pflask-0.2 avrdude-6.1 flashrom-0.9.7 oxygen-icons-4.14.2 r-servr-0.2 r-data.table-1.9.6 r-htmlwidgets-0.5 r-dplyr-0.4.3 r-devtools-1.9.1 python2-rpy2-2.6.0 python-rpy2-2.6.0 rsem-1.2.20 r-qtl-1.37-11 slepc-complex-openmpi-3.6.2 mumps-openmpi-5.0.1 superlu-dist-3.3 dealii-openmpi-8.2.1 bless-1p02 fftw-openmpi-3.3.4 guile-charting-0.2.0 accountsservice-0.6.40 zynaddsubfx-2.5.2 non-sequencer-1.9.5-1d9bd576 emacs-pdf-tools-0.60 mupdf-1.6 openimageio-1.5.18 ctl-1.5.2 slim-1.3.6 python2-scikit-image-0.11.3 raincat-1.1.1.3 guile-sly-0.1 mesa-utils-8.2.0 i3-wm-4.10.3 xnee-3.19 racket-6.2.1 sawfish-1.11 lxappearance-0.6.1 lxtask-0.1.6 pcmanfm-1.2.3 lxrandr-0.3.0 sra-tools-2.5.4 htsjdk-1.129 ruby-atoulme-antwrap-0.7.5 pspp-0.8.5 arandr-0.1.8 wicd-1.7.3 gourmet-0.17.4 gajim-0.16.3 patchage-1.0.0 gpscorrelate-1.6.1.365f6e1b3f pinentry-0.9.5 xournal-0.4.8 glade-3.8.4 lxterminal-0.2.0 gkrellm-2.3.5 geeqie-1.1 geda-gaf-1.8.2 dvdisaster-0.72.6 azr3-1.2.3 calf-0.0.60 ir-1.3.2 gnubik-2.4.2 pcb-20140316 gst-plugins-ugly-1.6.1 guix-0.9.0.5c36edc skribilo-0.9.2 a2ps-4.14 emacs-w3m-1.4.483+0.20120614 orpheus-1.6 ripperx-2.8.0 emms-4.0 abcde-2.7 mpd-mpc-0.27 mpdscribble-0.22 ncmpcpp-0.6.7 ncmpc-0.24 pidgin-otr-4.0.1 libstdc++-doc-5.2.0 libstdc++-doc-4.9.3 manaplus-1.5.10.24 wayland-1.9.0 fish-2.2.0 openbox-3.5.2 guile-present-0.3.0 amule-2.3.1 gmtp-1.3.9 tuxguitar-1.2 conkeror-1.0pre1.20150730 lablgtk-2.18.3 gnubg-1.02 inklingreader-0.8 gxmessage-3.4.3 pavucontrol-3.0 zathura-cb-0.1.4 zathura-ps-0.2.2 zathura-pdf-poppler-0.2.5 zathura-djvu-0.2.4 vte-0.36.5 tilda-1.3.0 gnome-keyring-3.16.0 gsegrafix-1.0.6 d-feet-0.3.10 seahorse-3.16.0 gnome-terminal-3.16.0 gedit-3.18.1 gjs-1.44.0 xfce-4.12.0 devhelp-3.16.1 yelp-3.16.1 shotwell-0.22.0 hexchat-2.10.1 claws-mail-3.13.0 ibus-libpinyin-1.7.2 network-manager-applet-1.0.6 file-roller-3.10.0 gnome-session-3.18.1.2 epiphany-3.16.3 nestopia-ue-1.46.2 gamine-1.4 sfxr-1.2.1 transmission-2.84 gnome-mines-3.16.0 aisleriot-3.16.1 gnucash-2.6.9 key-mon-1.17 eog-3.16.2 gnome-themes-standard-3.18.0 gnome-klotski-3.16.1 gnome-settings-daemon-3.16.0 gnumeric-1.12.17 xboard-4.8.0 fvwm-2.6.5 hop-2.4.0 patches-0.0.26d7dbc magit-svn-2.1.1 emacs-typo-1.1 emacs-flycheck-0.23 emacs-butler-0.2.4 emacs-auctex-11.88.6 emacs-debbugs-0.7 emacs-ob-ipython-20150704.8807064693 bigloo-really-sucks-4.2a.20141017 guile-emacs-20150512.41120e0 emacs-no-x-toolkit-24.5 abiword-2.8.6 emacs-foo-bar-patched-42 evince-3.18.1 rhythmbox-3.2.1 caribou-0.4.19 totem-3.16.1 libchamplain-0.12.10 mutter-3.18.1 gimp-2.8.14 wesnoth-1.12.4 gvfs-1.24.1 python2-ipython-3.2.1 python-numexpr-2.4.4 python-h5py-2.4.0 python-biopython-1.65 python-statsmodels-0.6.1 python-scikit-image-0.11.3 python-scikit-learn-0.16.1 python-seaborn-0.5.1 idr-2.0.0 python-ipython-3.2.1 python2-numexpr-2.4.4 macs-2.1.0.20140616 seqmagick-0.6.1 crossmap-0.2.1 rseqc-2.6.1 python2-statsmodels-0.6.1 miso-0.5.3 deeptools-1.5.11 python2-warpedlmm-0.21 clipper-0.3.0 pbtranscript-tofu-2.2.3.8f5467fe6 grit-2.0.2 couger-1.8.2 proof-general-4.2 enblend-enfuse-4.1.3 shogun-4.0.0 xsensors-0.70 wxmaxima-15.04.0 fastcap-2.0-18Sep92 simple-scan-3.17.4 hydra-20150407.4c0e3e4 gerbv-2.6.1 dunst-1.1.0 evas-generic-loaders-1.16.0 terminology-0.9.1 rage-0.1.4 enlightenment-0.19.13 ath9k-htc-firmware-1.4.0 fcitx-4.2.8.6 soprano-2.9.4 python2-pyqt-4.11.4 polkit-qt-1-0.112.0 frescobaldi-2.18.1 keepassx-2.0-beta2 hydrogen-0.9.5.1 phonon-4.8.3 attica-0.4.2 libdbusmenu-qt-0.9.2 brdf-explorer-17 gpsbabel-1.5.0 librecad-2.0.6-rc alsa-modular-synth-2.1.1 jalv-1.4.6 ardour-4.4 avidemux-2.6.10 scribus-1.5.0 python-pyqt-5.5 pumpa-0.9.1 owncloud-client-2.0.2 lxqt-common-0.9.1 lxqt-session-0.9.0 tiled-0.13.1 bitcoin-core-0.11.0 calibre-2.41.0 qsynth-0.4.0 bind-utils-9.10.2-P2 mariadb-10.0.20 conky-1.10.0 powertabeditor-2.0.0-alpha8 libreoffice-5.0.0.2 evolution-data-server-3.18.2 flexbar-2.5 express-1.5.1 solfege-3.22.2 wine-1.7.52 mplayer-1.2 emotion-generic-players-1.16.0 cmus-2.7.1 mpd-0.19.10 strigi-0.7.8 gst-libav-1.6.1 guile-gnunet-0.0.383eac2 audacity-2.1.0 synfigstudio-1.0.2 retroarch-1.2.2 minetest-0.4.13 mars-0.7.5.1.c855d04409 love-0.9.2 mpv-0.13.0 emulation-station-2.0.1 guitarix-0.34.0 alta-minimal-0.0 alta-clang-0.0 dfc-3.0.4 alta-0.0 alta-gcc5-0.0 alta-gcc4.8-0.0 alta-gcc4.7-0.0 libwebsockets-1.3.dbg rdup-1.1.14

Eric, I would welcome your feedback on this.  I would think the graph
helpers in (gnu packages) that were used by ‘guix refresh -l’ can now be
removed; WDYT?

There’s still room for improvement: ‘guix refresh -l’ could look at the
graph that includes origin objects and count the number of dependents of
the origin, rather than the number of dependents of one package that
uses it.  (Well, that’s the information we’re after when we want to
upgrade, but when we just want to change the package, that’s not what we
want.)

Cheers,
Ludo’.

I'm running guix-daemon with --no-substitutes, but didn't realize that
libarchive actually had so many dependent packages when I was building
it:)

Anyway, the new version looks great!
