Currently the tool prints problems right as it is checking the code
without an intermediate error representation. However for various reasons
it would be beneficial to have an intermediate error type:
- It makes the code cleaner, having all errors in one place
- It allows printing the error in different ways, e.g. for a future
--json mode
This commit prepares for an incremental refactoring for an intermediate
error/problem representation. Most notable is that we want to be able to collect
multiple errors/problems and not just exit on the first one.
We introduce the type alias CheckResult and CheckError (later renamed to
NixpkgsProblem), where CheckError allows collecting multiple
CheckErrors using the utility function flatten_check_results (later
renamed to check_result::sequence)
The write_check_result function is only temporarily introduced to help
refactoring, it's removed again in later commits.
Implement new 'buildTeXEnv' to leverage multi-output packages and provide
__overrideTeXConfig/withPackages for modifying the configuration or adding
packages. The override mechanism is prefixed until stabilized.
Allows detecting whether attributes are overridden in all-packages.nix.
In a future commit we'll use this to detect empty arguments being set in
all-packages.nix and complain about that.
When specifying the `builder` attribute in `stdenv.mkDerivation`, this
will be effectively transformed into
builtins.derivation {
builder = stdenv.shell;
args = [ "-e" builder ];
}
This also means that `default-builder.sh` is never sourced and as a
result it's not guaranteed that `$NIX_ATTRS_SH_FILE` is set to a correct
location[1].
Also, we need to source `.attrs.sh` to source `$stdenv`. So, the
following is done now:
* If `$NIX_ATTRS_SH_FILE` points to a correct location, then use it.
Directly using `.attrs.sh` is problematic for `nix-shell(1)` usage
(see previous commit for more context), so prefer the environment
variable if possible.
* Otherwise, if `.attrs.sh` exists, then use it. See [1] for when this
can happen.
* If neither applies, it can be assumed that `__structuredAttrs` is
turned off and thus nothing needs to be done.
[1] It's possible that it doesn't exist at all - in case of Nix 2.3 or
it can point to a wrong location on older Nix versions with a bug in
`__structuredAttrs`.
We seem to have enough tests to run into this now:
error: creating symlink from '/private/tmp/nix-build-nixpkgs-check-by-name.drv-0/source/test-tmp/var/nix/gcroots/profiles' to '/private/tmp/nix-build-nixpkgs-check-by-name.drv-0/source/test-tmp/var/nix/profiles': File exists
On Darwin, /tmp is sometimes a symlink to /private/tmp, which couldn't
be handled before:
error: access to canonical path '/private/var/folders/xp/9_ry6h9x6l9gh_g32qspz0_40000gp/T/.tmpFbcNO0' is forbidden in restricted mode
This both fixes that and adds a test to make sure it can't happen again
This reverts commit d33a309f2c9f85c28cb897e623503f210057a77a.
commit caused ofborg-eval to fail with

$ nix-build pkgs/top-level/release.nix -A tests.cc-wrapper.gcc10Stdenv.aarch64-darwin
error: evaluation aborted with the following error message: 'cannot find attribute `tests.cc-wrapper.gcc10Stdenv''
```
on the 3 other platfomrs the attr is there
ignore `llvmPackages_latest`, it's an alias and it'll be a duplicate.
ignore `llvmPackages_git`, it's not supposed to be used in nixpkgs and
may be broken.
This introduces the `pkgs/by-name` directory as proposed by RFC 140.
Included are:
- The implementation to add packages defined in that directory to the
top-level package scope
- Contributer documentation on how to add packages to it
- A GitHub Actions workflow to check the structure of it on all PRs
most tests use debian-devscripts' hardening-check, so only work on
ELF systems and can only detect a limited subset of flags.
some extra tests actually execute fortify-protected programs and
should be slightly more universally applicable.
- Better filesystem case-sensitivity heuristic
We shouldn't assume that Linux is always case-sensitive.
- Don't include case-sensitive filename in tree
Was used for tests, but this broke channel updates because there's a
check to make sure there's no case-sensitive files!

This commit does the following two things:
1. Changes the Haskell package used in the extraDependencies test from
releaser to conduit. The reason for this is that conduit is more
of a "core" package in Haskell, and it is more likely to always be
working. (If conduit is not compiling, then large chunks of Hackage
won't be working.)
2. Tighten up the GHCi test to actually use the package from
extraDependencies. It appears that GHCi can fail to import the
package from extraDependencies, and that doesn't cause GHCi to
return an error code, which means the test isn't actually testing
anything.
This new change makes it so that if the package from
extraDependencies is actually not included for some reason, then
this shellFor test should fail.

This commit adds `pkgs.test.cross.sanity`, which is meant to be a
carefully curated list of builds/packages that tend to break when
refactoring our cross-compilation infrastructure.
It should strike a balance between being small enough to fit in
a single eval (i.e. not so large that hydra-eval-jobs is needed)
so we can ask @ofborg to check it, yet should have good examples
of things that often break. So, no buckshot `mapTestOnCross`
calls here.
Makes overrideAttrs usable in the same way that `override` can be used.
It allows the first argument of `overrideAttrs` to be either a function
or an attrset, instead of only a function:
hello.overrideAttrs (old: { postBuild = "echo hello"; })
hello.overrideAttrs { postBuild = "echo hello"; }
Previously only the first example was possible.

This change adds a flag to update shebang paths that point to the Nix
store. This is particularly useful when a cross-compiled package uses
same script at compile-time and run-time, but the interpreter must be
changed since hostPlatform != buildPlatform.
With a recent hackage update, turtle stopped compiling on ghc94. This
commit changes the tests.haskell.incremental test to use the temporary
package instead of turtle.
