This makes the test faster (by removing it and replacing it with a
`TestScmInput` module that exports the `testScmInput` subroutine). Now,
all the input tests can be run in parallel.
Some of the `tests/jobs/*-update.sh` scripts were "broken" (e.g. tests
failed for various reasons on my machine), so I fixed those up as well.

This will make it easier to track specifically where queries are being
made from (assuming a `log_line_prefix` that includes `%a` in the
postgres configuration).
projects.xml and declarative-projects.xml were merged with xmllint, and
then I ran that to convert files
for i in *.xml; do pandoc -s -f docbook -t markdown $i -o ${i/xml/md}; done
The queue runner used to special-case `localhost` as a remote builder:
Rather than using the normal remote-build (using the
`cmdBuildDerivation` command), it was using the (generally less
efficient, except when running against localhost) `cmdBuildPaths`
command because the latter didn't require a privileged Nix user (so made
testing easier − allowing to run hydra in a container in particular).
However:
1. this means that the build loop can follow two discint code paths depending
on the setup, the irony being that the most commonly used one in production
(the “non-localhost” case) isn't the one used in the testsuite (because all
the tests run against a local store);
2. It turns out that the “localhost” version is buggy in relatively obvious
ways − in particular a failure in a fixed-output derivation or a hash
mismatch isn't reported properly;
3. If the “run in a container” use-case is indeed that important, it can be
(partially) restored using a chroot store (which wouldn't behave excactly
the same way of course, but would be more than good-enough for testing)
The current check happening in jobsets is incorrect.
The wanted constraint is stated as follow :
- If type is 0 (legacy), then the flake field should be null, and
both nixExprInput and nixExprPath should be non-null
- If type is 1 (flake), then the flake field should be non-null, and
both nixExprInput and nixExprPath should be null
The current version will not catch (i.e. it will accept) situations
where you have for instance :
type = 1, nixExprPath null, nixExprInput non-null, flake non-null
This commit fixes that.
I split(ted) that into two constraints, to make it more readable and
easier to extend if a new type appears in the future.
The complete query could be instead :
( type = 0
AND nixExprInput IS NOT NULL AND nixExprPath IS NOT NULL AND flake IS NULL )
OR ( type = 1
AND nixExprInput IS NULL AND nixExprPath IS NULL AND flake IS NOT NULL )
(but an "OR" cannot be split, hence the other formulation)
DBIx likes to eagerly select all columns without a way to really tell
it so. Therefore, this splits this one large column in to its own
table.
I'd also like to make "jobsets" use this table too, but that is on hold
to stop the bleeding caused by the extreme amount of traffic this is
causing.
The database has these constraints:
check ((type = 0) = (nixExprInput is not null and nixExprPath is not null)),
check ((type = 1) = (flake is not null)),
which prevented switching to flakes in a declarative jobspec, since the
nixexpr{path,input} fields were not nulled in such an update
