With cabal-install >= 3.12, we need to adjust our cabal-install overlay
once again.
- Due to the new dependency semaphore-compat, which appears to require
unix >= 2.8 it is very difficult to get to work for GHC < 9.6 (but
probably possible). Technically, using pkgs.cabal-install should
always be fine, so there's no strict need for cabal-install to work
with every GHC. Let's drop support for GHC < 9.6 for now.
- Make sure that cabal-install-solver also uses the latest version
always.
- Due to Cabal 3.12, we need to deviate from Stackage for
hackage-security. cabal-install does support the standard version of
resolv now, though.

Add capability to update to an out of date solver in update-stackage.sh.
In practice, almost all requests to Hydra take longer than the default
timeout of 30 seconds.
This commit bumps all requests to the max timeout of 15 minutes. This
should hopefully make the hdyra-report.hs script more reliable and fail
less.
This change adds a flag --slow to hydra-report.sh get-report which
causes it to fetch the cheap evaluation overview endpoint (which only
contains build ids and meta data). The gathered information is then used
to request each build's status individually instead of in bulk which is
very slow, but useful as a last resort if the bulk endpoint times out.
Since every failure in the jobset means one request to get the log when
generating the list of newly broken packages, we need to add an option
to disable log requesting in case a lot of new breakage needs to be
entered.
If we want to push only one branch, we'll have to specify branch and
remote explicitly. Pushing to origin doesn't work for everyone, since
some of us have a origin remote that can't be pushed to. Using plain
`git push` has the problem that it'll try pushing all checked out
branchs which fails e.g. if some branches (staging, staging-next, …) are
behind their remote counterparts.
The solution is to require everyone to configure a per branch pushRemote
for haskell-updates which will then be used by merge-and-open-pr.sh.
cabal-install 3.10 has some quirky new logic for config, cache, …
directory discovery. We reimplement this in this simple bash script,
additionally respecting the CABAL_DIR environment variable.
This update adds support for $CABAL_DIR as well as the new
$XDG_CACHE_HOME location of the hackage db.
Since we maintain hackage-db, having the latest version always is nice
even though it has more reverse dependencies than the other libraries we
maintain.
Add a newtype for a package name and a package set. This is less for
correctness, and more just to make the code a little easier to read
through without having to keep in mind what each Text refers to.
nixpkgs:trunk also builds aarch64-darwin these days, so this forces our
hand a little bit. We can still refuse to care about failures _too_
much, but at least we will stop merging as big a rebuilds as we are
currently.
`ghc-pkg list` tells us everything hackage2nix needs to know. In the
past the core-packages list and compiler setting in hackage2nix was
maintained manually which inevitably leads to it being forgot once in a
while – this will then mess with flag resolution when generating the
package set in some cases. Luckily, we can just let a simple derivation
do this for us.
Resolves#202621.
Since we now have a versioned configuration-ghc-*.nix file for GHC HEAD,
we don't need to add a super special case to the package set logic in
test-configurations.nix anymore. We can just create a versioned
attribute for the ghcHEAD package set (which is not exposed) and keep
using the normal discovery logic.
The only tricky bit is that GHC HEAD's configuration file is named after
the GHC release that will be branched off from it, so a little bit of
arithmetic is involved.
The Haskell Hydra report generator
(`maintainers/scripts/haskell/hydra-report.hs`) uses this
`maintainer-handles.nix` script for generating a mapping of email
addresses to GitHub handles.
This `maintainer-handles.nix` script is necessary because the Haskell
Hydra report generator gets Hydra job status info as input, but needs to
ping users on GitHub. Hydra job status info only contains user emails (not
GitHub handles). So the `maintainer-handles.nix` script is necessary
for looking up GitHub handles from email addresses.
This commit fixes the `maintainers-handles.nix` code to ignore
maintainers that don't have email addresses. The code was originally
assuming that all maintainers have email addresses, but there was
recently a maintainer added without an email address.
- use `restrict-eval` so that we're not affected by the user's environment
- use jq instead of the horrible echo+sed hack
The second point also fixes the indentation before each line to be two
spaces instead of one, so I set it back to one space to avoid a diff.
