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.
This allows more flexible control over the working directory. Values for workingDir must always start
with a / and will then be relative to the repo root.
The upside is that postgrest-with-postgresql-xxx postgrest-test-io works as expected
now. The downside is, that postgrest-with-postgresql-xxx psql now starts without
any schema. This now needs an explicit postgrest-with-postgresql-xxx -f path/to.sql
to do anything useful.
Resolves#2864
The recent nixpkgs update gave us a new version of vegeta. This version includes a new
DNS cache features - which unfortunately doesn't play well with unix sockets. Disabling
the DNS cache makes requests succeed again.
* Write vegeta output to file explicitly.
The previous version using `tee` captured the standard
output of the `withPgrst` helper, too, causing weird
errors when those had unexpected output.
* Log and fail the postgrest build explicitly.
In situations such as changing nix dependencies, the
`cabal build` run could fail, but this wasn't visible
in CI.
With these changes, the load test now fails with a nice
error message when the build fails.
