hedgewars uses ghc directly
While games/hedgewars has working cabal files in both directories
tools/pas2c/pas2c.cabal
gameServer/hedgewars-server.cabal
they are not used by the build process. The porter is responsible for installing the requisite haskell libraries listed in INSTALL.md. One lucky break is this seems to be a dependency of the -server subpackage and as such can be potentially handled separately.
Haskell binary building with cabal new-build
While looking at Haskell binary ports, a couple of approaches seem
possible.
- Embed Haskell libraries into ports, build binaries from them.
- Build binaries with
cabal new-build
The status quo is 1. This has a few benefits: it exists, libraries
are reused by multiple ports reducing build costs. There are
drawbacks: the ports tree contains a duplicate (and sometimes
inconsistent) specification of Hackage information. Because of this,
upgrades are a big pain and there's a version of DLL (cabal) hell in
that a single compatible library version needs to be chosen for all
ports.
An alternative is 2. Many hs-* library ports could go away by making
each binary port (e.g. darcs, shellcheck) build their own library
dependencies in its sandbox. This will reduce maintenance costs and
avoid any possibility of version conflicts. There are drawbacks: it
doesn't exist, the same library will get built for each binary using
it. We also won't be able to switch to a completely clean 2. Some
ports (like xmonad) use Haskell build as a configuration mechanism. We
still need to provide a subset of ports-embedded libraries in the
style of 1.
If we are to keep doing 1, we should automate maintenance as much as
possible. portgen is an option and so is building a port targeting
version of cabal2bazel (once brought up to date)
If the majority of OpenBSD users only care about using the binaries, I
believe we will serve them better by doing 2 for the binary providing
ports.
Some unknowns apply to design 2:
- how well we can specify the Hackage snapshot
- how hermetic we can make it (force tarball fetching to happen
before runningcabal new-build)
Ports with Haskell binaries:

Looks like ghc tries to map a particular address, the kernel gives it a different address, ghc munmaps and keeps retrying until it gets the address it wants.

ANN module crashes ghc 8.6.4 with a bus error on OpenBSD
I'm in the process of upgrading to GHC 8.6.4 on OpenBSD-6.5-amd64-stable on this branch in repo.
I hit a bus error when porting fgl, but then reduced the problem to a
trivially reproducible one below. I've also stored a log from -v9 run

This is probably fine and should be fixed in the test suite since ExitFailure Int is documented as

getCPUTime returns fixed value with -threaded
This test fails:

Once instrumented with some prints the output is puzzling:

In my quest to update the ports tree to ghc 8.6.4 I arrived at a fork re
ShellCheck.
The first blocker is ANN/TemplateHaskell is broken per #1 enough that
patching is required to get rid of all ShellCheck testing code. Now,
the next snag is the ancient version of ShellCheck in ports. At least
a couple of places need to be patched for Semigroup and MonadFail
issues. My natural impulse would be to upgrade ShellCheck to the most
recent version 0.6.0, except it has a larger dependency
set and at least aeson is not in ports. At this point I'm not sure
which way to go. Is the new version with a larger set of deps a better
option? Or the patched-up old version? Since I personally don't use
ShellCheck, I can't make the call easily. Opinions? Patches?
