@jneira I had to flush the cache on CircleCI for this to pass. Could the azure failures be something like that?

[jneira]

Mmm some linux failed with

Failures:

  test/dispatcher/Main.hs:297:7: 
  1) functional dispatch instantly responds to failed modules with no cache with the default
       expected: ("req7",Just [])
        but got: ("req8",Nothing)

  To rerun use: --match "/functional dispatch/instantly responds to failed modules with no cache with the default/"

Randomized with seed 429502550

i think i saw that error before, i've just rerun the failing jobs to see if it is transient

[jneira]

Linux errors are gone, only left:

• build error with stack+stack.yaml: i don't see the concrete error 🤔
• error running cabal-hie-install latest in windows: the second one

i would try both locally

[jneira]

cabal-hie-install latest was my fault fix in #1627

[alanz]

Ok. Heads up, I am rebasing this PR on the hie-bios update one, and some things are changing. We will see how it ends up.

Aside, I had to blow away my cabal store and rebuild it, to get rid of weird errors about diamond deps.

[jneira]

We cant build hie with ghc-8.2.2, if we use it in stack.yaml we should remove it from azure ci.
I think the plan was keeping ghc-8.6.5 in stack.yaml until ghc-8.8.3 lands.

[alanz]

Can we get azure to use stack-8.6.5.yaml instead? Which makes it clear

[jneira]

mmm, there already is a job that uses stack-8.6.5.yaml. We can remove the one that uses stack.yaml

[jneira]

Now, builds with ghc-8.4.3 are failing with:

[jneira]

I am working to fix ghc-8.4.3 builds

[jneira]

There is a failing unit test but ,as @fendor as noted , it was introduced by #1261 so i think we can merge this.

[alanz]

@jneira thanks
