This reduces our Template Haskell dependencies.
The commit hash never made it into the nix-based static executable
anyway. Since we'd like to move to produce more executables via nix in
the future, it will be hard to maintain the commit hash.
The cabal-provided Paths_ module allows us to use the version number
from postgrest.cabal. This can be done equally well with the GHC-defined
CPP macro "VERSION_postgrest".
By making this change we avoid the inclusion of the Paths_ module, which
also stores some paths related to the cabal configuration. Those are
problematic to go into the final executable, because for nix-based
builds those are paths to the /nix/store/... - which means that our
static executable then depends on those paths.. and we can't build a
minimal docker image anymore.
To counter this, we have been using dead code elimination when building
the static executable. This has been working well, but there is a
problem on aarch64-darwin, which we will hit once can finally make our
way there: GHC on aarch64-darwin (or darwin in general?) can't do dead
code elimination - and thus it'd be impossible to create those minimal
docker images for those platforms. More information upstream in nixpkgs:
https://github.com/NixOS/nixpkgs/issues/318013
Since we changed our release workflow, we have adjusted:
- the docs to use postgrest.org/en/v12/ -style URLs, i.e. only using the
major component.
- the pre-release / devel versions to contain only two instead of four
version parts, i.e. currently 12.3.
Timing dependent tests in the IO tests don't work too well when the next
commit increases the JWT parsing performance.
The remaining IO tests are for coverage and basic breakage. Loadtests
are adapted so that performance regressions for JWT caching would be
detected that way.
The former depends on th-orphans which does not cross-compile well,
because of template haskell usage.
neat-interpolation is also much better maintained.
This also potentially helps with packaging for Debian/Ubuntu in #2273.
Contravariant.Extras uses Template Haskell, which is hard to
cross-compile. Reducing usage of Template Haskell with the ultimate goal
of solving all cross compilation challenges.
This seems to happen on nix 2.22 only, v2.21 in CI and v2.20 locally work fine. The error is:
vendor folder is empty, please set 'vendorHash = null;' in your expression
For full logs, run 'nix-store -l /nix/store/kxnnr344n7gsxzc6kycj19hs19rvddjj-slocat-go-modules.drv'.
error: 1 dependencies of derivation '/nix/store/x9w480k36a11i99m6zp12d5cjijsn3lm-slocat.drv' failed to build
Since the slocat module doesn't actually have any dependencies, this shouldn't matter much.
