Initial GHC 9.2 bounds

[bergmark]

I'm filing this pre-emptively to keep track of our GHC 9.2 status.

We have not planned a date for the nightly upgrade to GHC 9.2 yet

As usual when there is a major GHC upgrade of stackage nightly, we need to disable packages that don't support the GHC version. This may happen transitively if your package depends on another package that doesn't have GHC 9.2 support. We also drop most other upper bounds since new releases are usually needed for the new GHC.

As a maintainer there is unfortunately no way to get a quick overview of all your packages, but you can do something like this:

1. Find your maintainer section and note the packages that you maintain
2. Grep/search the file for any mentions of those package names

• If a package has a < 0 constraint or is commented out under the packages: section, that means it is no longer part of the nightly build.
• If it is present in one of the other sections such as expected-test-failures or skipped-benchmarks, that means we do not fully test the package.
• There's a comment indicating why a component has been disabled

For testing packages against GHC 9.2, you can set resolver: ghc-9.2 in your stack.yaml or use cabal -w ghc-9.2.1.

If you have questions about this process, feel free to ask here. If you have questions about the status of a specific package, I think it's better to file a new issue.

There is no need to let us know if a package has been updated. This process is (semi) automated and any updates will be reflected here once we re-run it.

N.B.: We do not compile packages to generate this list, so compilation/test failures will not show up here

• Does not build with GHC 9.2 or 9.4 agda/hs-tags#2

xeno is broken with GHC9.2 - ocramz/xeno#53

Here are the top disabled packages with the number of direct dependents. Due to how the automation works around this, the numbers are lower bounds on the total. Thee numbers are not only for GHC 9.2 as packages are disabled for other reasons as well.

I made a more proper solution to count how many transitive dependents are disabled:

memory is disabled with 276 dependents
gogol-core is disabled with 96 dependents
amazonka-core is disabled with 96 dependents
http-client-tls is disabled with 65 dependents
persistent is disabled with 41 dependents
x509 is disabled with 26 dependents
tls is disabled with 26 dependents
servant is disabled with 25 dependents
http-conduit is disabled with 22 dependents
yesod-core is disabled with 16 dependents
cryptonite is disabled with 15 dependents
streaming-bytestring is disabled with 14 dependents
hw-prim is disabled with 13 dependents
warp is disabled with 12 dependents
th-data-compat is disabled with 12 dependents
servant-server is disabled with 12 dependents
llvm-hs is disabled with 12 dependents
email-validate is disabled with 12 dependents
cryptohash is disabled with 12 dependents
securemem is disabled with 11 dependents
hw-bits is disabled with 11 dependents
stringable is disabled with 10 dependents

Looks like we need to release Agda again:

• Release Agda 2.6.2.2 agda/agda#5831

[andreasabel]

Reported:

• Support Cabal library 3.6 sol/hpack#484

[bergmark]

We're moving ahead with this. We'll file a report for disabled packages once the build has completed.
