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.
This script is heavily based on the script used to update all python
libraries at
pkgs/development/interpreters/python/update-python-libraries/update-python-libraries.py
The Octave Packages' website uses YAML as their basis, so we must
reformat to use YAML instead of JSON.
the script can output a list of sed commands to create the order it
expects to find. this was mainly useful for initially sorting the list,
but we'll keep it here for later reference.

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.
Previously when packages that required the git fetcher were updated, we
would wrongly rely on `nix-prefetch-url`, which would reliable break the
hash.
Instead we need to use `nix-prefetch-git` to determine the proper hash,
when the relevant attributes are present.
`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.
This will allow tests.pkg-config.defaultPkgConfigPackages to run on
hydra without breaking the tarball job.
Regarding the use of null, I'll quote 473ac96 which does lib.hydraJob.
By allowing null, we allow code to avoid filterAttrs, improving
laziness in real world use cases.
Specifically, this strategy prevents infinite recursion errors,
performance issues and possibly other errors that are unrelated to
the user's code.
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.
