While the website code is separate from the rest, the same rationale
than in the commit ada459875c ("Use a
released guix revision globally.") applies for using Guix 1.4.0
(having access to the Guix manual for the right Guix version, not
needing to run guix pull in some cases).
However if we do that we run into an issue where guix fails to find a
substitute for pandoc for Guix 1.4.0 for i686-linux. This results in
Guix bootstraping ghc and then building pandoc and its dependencies.
The ghc bootstrap is extremely long (many hours / few days on a
ThinkPad X200, and it takes more than one night inside a VM with 8
cores and 16 GiB of RAM that runs on a KGPE-D16). Not running the ghc
tests also doesn't speed up the build enough to be practical.
However while the pandoc substitutes are not available on
ci.guix.gnu.org, they are available on bordeaux.guix.gnu.org which is
also in the default substitute servers.
So the workaround is to tell users to make sure to authorize
bordeaux.guix.gnu.org and then to force its use if it is authorized.
This still enable users to not use substitute (for security reasons)
if they want to.
To do the detection we use guix repl as the guix command is supposed
to be available and it also has access to Guix's guile modules.
In addition, running ./autogen.sh && ./configure && make check results
in the following error without this commit:
guix time-machine --commit= -- shell --system=i686-linux --container
--network --emulate-fhs --share=`realpath ../` bash coreutils
findutils git grep nss-certs pandoc sed -- ./build.sh
guix time-machine: error: Git error: unable to parse OID - too short
make: *** [Makefile:696: build] Error 1
This was broken by the commit 07e9cbd12c99e39d0bc0b8449423bd914bb92b10
("website: properly handle the dot dependency.").
However if we bisect it, we instead find that the commit
f8874d77803426cc01305e7f895284dbe7caae00 ("website: remove
history/git-history.jpg") broke 'make check'.
This is because history/git-history.jpg is supposed to be generated
but it was included in git in the commit
388c0ef3d0 ("website: add history page
of the GNU Boot git repositories.") and so once we starts generating
the file again, 'make check' breaks.
So we modified the commit 388c0ef3d0
("website: add history page of the GNU Boot git repositories.") to not
add history/git-history.jpg to properly bisect it.
