Before 46c68ad both "@" and " as " could be used in the same line like
the following:
vimwiki/vimwiki@dev as vimwiki-dev
After 46c68ad this gives an error due to the split URI still erroneously
including the " as [name]" at the end, due to splitting from the wrong
variable.
configuration-nix.nix uses builtins.intersectAttrs to not any overrides
for packages not present in `super` (presumably for use outside of
nixpkgs?). To accomodate it, we pass an attribute set with every
attribute of haskellPackages, but set to `null` as `super`, and — while
we're at it — a fix point as `self`.
While being able to test them is neat (on x86_64-linux they work very
well, actually), we usually don't want to do this, since the set is
only (recommended to be) used to bootstrap GHC. Consequently there is
almost no binary cache and testing them mostly leads to unenlightening
and seemingly endless compilation.
The added nix expression allows maintainers to check for regressions in
the configuration overlays employed by haskellPackages and friends. The
reasoning behind this is that, if we add an override for something, it
should also build. To test this fact, we extract all attributes touched
by a configuration and obtain all relevant derivations corresponding to
it which can then be thrown into nix-build --keep-going.
I've been using this expression to verify configuration-ghc-9.2.x.nix
for a week or so which works quite well. The amount of stale overrides
in other configuration makes it a bit more painful for other use cases
at the moment.
The "0.5.0-1" rockspec on luarocks has a bug, resulting in it pulling
the current git master version, which is what we have effectively been
using.
Given that 0.5.0-1 is the latest release, is 6 years old, and that there
have been some bug fixes since then, we do actually want to be using the
git master version, but we also want to be using the correct rockspec
(particularly as alt-getopt has been replaced by argparse in the `moon`
binary).
Avoiding passthru itself was the right direction, but not a
complete solution. Passthru attributes typically do not contain
dependencies, but rather extra paths that are not relevant to
the build itself.
Whether we want to include all (passthru) test dependencies this
way can be debated, but removing them makes this expression more
robust.
When updating a package using nix-update-script with `--argstr commit true`,
update.nix would not detect the changes because nix-update would stage them
and `git diff` would be empty.
We now detect both staged and unstaged changes to handle this use case.
- luarocks-nix: bumped to pass args too, `package_X = callPackage ...`.
It allows to remove the annoying `with self`.
This new version disables tests (because broken) and now emits derivation
with a callPackage in front.
- replaced X.override with lib.overrideLuarocks, it should be used
whenever buildInputs/extraVariables is changed since it impacts the
generated luarocks config.
Once structured attributes are in, it will be easier to have the
luarocks config generated by a hook and we probably will be able to
replace all overrideLuarocks by overrideAttrs.
* maintainers/scripts/rebuild-amount.sh: report parallelism setting
This slightly helps discovering parallelism support.
* maintainers/scripts/rebuild-amount.sh: add basic example
It's not clear if script should be used against HEAD or HEAD^.
Let's have a copyable example.
* maintainers/scripts/rebuild-amount.sh: convert tabs to four spaces
One notable change is here-document conversion.
Before:
<TAB>cat <<-FOO
<TAB>...
<TAB>FOO
After:
<sp><sp><sp><sp>cat <<FOO
<sp><sp><sp><sp>...
FOO
Note seemingly misaligned 'FOO': '-FOO' understands leading tabs,
but not spaces.
I noticed this minor grammar mistake when running update.nix, and then
while grepping to find the source I noticed we had it a few times in
Nixpkgs. Just as easy to fix treewide as it was to fix the one
occurrence I noticed.
Upstream is working on some major deprecations, being on a HEAD commit
will not be a good plan going forward.
Remove double `busted` in `checkInputs` - keep only 1.
If the script is executed in a CI (like in github actions, with the
install-nix-action) it fails. This changes fixes that use case. In that
scenario, you should provide the --no-commit flag.
