stdenv: allow specifying a eval issuee handler 2017-12-12 18:08:11 -05:00
Vladimír Čunát 76bf375a16
stdenv checkMeta: throw -> trace
- tracing seems annoying enough
- we get errors for all packages instead of aborting on the first one
- easier to differentiate from unwanted packages (broken, unfree, etc.)

Merge pull request #31775 from obsidiansystems/stdenv-both-propagated-files
stdenv setup: Always use both propagated files

John Ericson da19c34d0f stdenv setup: Always use both propagated files
This continues #23374, which always kept around both attributes, by
always including both propagated files: `propgated-native-build-inputs`
and `propagated-build-inputs`. `nativePkgs` and `crossPkgs` are still
defined as before, however, so this change should only barely
observable.

This is an incremental step to fully keeping the dependencies separate
in all cases.

I find the separation of concerns, accumulating, then processing, easier

part will become more complex.

John Ericson 4d4f94cde4 treewide: Depend on targetPackages.stdenv.cc.bintools instead of binutils directly
One should do this when needed executables at run time. It is more
honest and cross-friendly than refering to binutils directly, if one
neeeds the default binary tools for the target platform, rather than
binutils in particular.

Dan Peebles b426c85ce2 Get rid of most @rpath nonsense on Darwin
This requires some small changes in the stdenv, then working around the
weird choice LLVM made to hardcode @rpath in its install name, and then
lets us remove a ton of annoying workaround hacks in many of our Go
packages. With any luck this will mean less hackery going forward.

John Ericson d349f9a340 cc-wrapper: Use stdenvNoCC to build
cc-wrapper may wrap a cc-compiler, but it doesn't need one to build
itself. (c.f. expand-response-params is a separate derivation.) This
helps avoid cycles on the cross stuff, in addition to removing a
useless dependency edge.

I could have been super careful with overrides in the stdenv to avoid
the mass rebuild, but I don't think it's worth it.

that has no effect on semantics as the os is already guaranteed to be

Revert "Merge pull request #28557 from obsidiansystems/binutils-wrapper"
This reverts commit 0a944b345e, reversing
changes made to 61733ed6cc.

I dislike these massive stdenv changes with unclear motivation,
especially when they involve gratuitous mass renames like NIX_CC ->
NIX_BINUTILS. The previous such rename (NIX_GCC -> NIX_CC) caused
months of pain, so let's not do that again.

Orivej Desh a09d9e7cd4 stdenv-setup: fix substituteAll with set -eu
Environment variable filter in substituteAll was not precise and produced
undefined and invalid variable names.  Vladimír Čunát tried to fix that in [1],
but `env -0` did not work during Darwin bootstrap, so [2] reverted this change
and replaced an error due to invalid variables with a warning.  Recently in #28057
John Ericson added `set -u` to `setup.sh` and undefined variables made the setup
fail during e.g. `nix-build -A gnat` with `setup: line 519: !varName: unbound
variable`.

gawk: refactor
- Don't build with libsigsegv by default.  The build apparently attempted
  to link against it, but it never retained the reference anyway...
- Side effect: stdenv bootstrapping needs no libsigsegv anymore.
- Run checks, but only in the interactive gawk by default on Linux,
  so that stdenv bootstrap isn't slowed down (by glibc locales, etc.).
- xz should be no longer needed in inputs, as we have it in stdenvs now.

The whole change was triggered by some used kernel versions still
breaking libsigsegv tests #28464.

John Ericson 81194eef45 stdenv-setup: Use set -u as much as possible
Older bash version, like those in the bootstrap tools and on macOS,
currently confuse variables defined as an empty array with undefined
variables. `${foo+"${foo[@]}"}` will prevent `set -u` problems with
empty arrays and older without making a single '' in the empty case.

Care is taken to `set +u` when running hooks so as to not break existing
packages.

Tuomas Tynkkynen 3e9f76774a
nixpkgs release: Fix Darwin-only jobs
Currently the logic of generating nixpkgs Hydra jobs is to walk through
the pkgs evaluated for system = "x86_64-linux", collect any derivations
and their meta.platforms values. However, that doesn't work for
packages whose meta.platforms doesn't include x86_64-linux, as just
evaluating their meta attribute raises an error so they get skipped
completely.

As a less-intrusive fix (i.e. anything than rewriting the current package
enumeration logic), allow passing `config.allowUnsupportedSystem = true`
to permit evaluating packages regardless of their platform and use that
in the package listing phase.

Fixes #25200

needed to be converted to to append a configureFlags list instead of
string due to the normalization.

Thanks @vcunat for alerting me to the issues---sorry I did not catch
them before merging my own PR.

John Ericson e826a6a247 stdenv: Move some logic from cross adapter to stdenv proper
Eventually the adapter will be removed.  Moved is

 - Name suffix from hostPlatform

 - configurePlatforms

   To not cause more breakage, the default is currently [], but
   eventually it will be [ "build" "host" ], as the cross adapter makes
   it today.

Dan Peebles 0419452113 Fix Darwin stdenv to work on 10.13
The main changes are in libSystem, which lost the coretls component in 10.13

a non-constant format string, so we've needed to patch a lot of programs that
use gnulib.

John Ericson 3cb745d5a6 stdenv: Store one package per line in nix-support/propagated-*
This makes those files a bit easier to read. Also, for what it's worth,
it brings us one baby step closer to handling spaces in store paths.

Also, I optimized handling of many transitive deps with read. Probably,
not very beneficial, but nice to enforce the pkg-per-line structure.
Doing so let me find much dubious code and fix it.

Two misc notes:

 - `propagated-user-env-packages` also needed to be adjusted as
   sometimes it is copied to/from the propagated input files.

 - `local fd` should ensure that file descriptors aren't clobbered
   during recursion.

See previous commit for what was done to `binutils` to make this
possible.

There were some uses of `forcedNativePackages` added. The
combination of overrides with that attribute is highly spooky: it's
often important that if an overridden package comes from it, the
replaced arguments for that package come from it. Long term this
package set and all the spookiness should be gone and irrelevant:

binutils, i.e. the old `binutils`.

`buildPackages` chains like this are supposed to remove the need for
all such `*Cross` derivations. We start with binutils because it's
comparatively easy.

John Ericson 75441dd64a Merge pull request #25194 from obsidiansystems/host-target-unconfuse
stdenv.cross is a silly attribute that needs to go leaving the well-defined hostPlatform and targetPlatform. This PR doesn't remove it, but changes its definition: before it tracked the target platform which is sometimes more useful for compilers, and now it tracks the host platform which is more useful for everything else. Most usages are libraries, falling in the "everything else" category, so changing the definition makes sense to appease the majority. The few compiler (gcc in particular) uses that exist I remove to use targetPlatform --- preserving correctness and becoming more explicit in the process.

I would also update the documentation aside mentioning stdenv.cross as deprecated, but the definition given actually erroneously assumes this PR is already merged!

Tuomas Tynkkynen ce56c99edc mkDerivation: Don't pass buildInputs to stdenv builder in nativeBuildInputs
When not cross compiling, nativeBuildInputs and buildInputs have
identical behaviour. Currently that is implemented by having
mkDerivation do a concatenation of those variables in Nix code and pass
that to the builder via the nativeBuildInputs attribute.

However, that has some annoying side effects, like `foo.buildInputs`
evaluating to `[ ]` even if buildInputs were specified in the nix
expression for foo.

Instead, pass buildInputs and nativeBuildInputs in separate variables as
usual, and move the logic of cross compilation vs. native compilation to
the stdenv builder script. This is probably a tiny bit uglier but
fixes the previous problem.

Issue #4855.

nixpkgs: allow packages to be marked insecure
If a package's meta has `knownVulnerabilities`, like so:

    stdenv.mkDerivation {
      name = "foobar-1.2.3";

      ...

      meta.knownVulnerabilities = [
        "CVE-0000-00000: remote code execution"
        "CVE-0000-00001: local privilege escalation"
      ];
    }

and a user attempts to install the package, they will be greeted with
a warning indicating that maybe they don't want to install it:

    error: Package ‘foobar-1.2.3’ in ‘...default.nix:20’ is marked as insecure, refusing to evaluate.

    Known issues:

     - CVE-0000-00000: remote code execution
     - CVE-0000-00001: local privilege escalation

    You can install it anyway by whitelisting this package, using the
    following methods:

    a) for `nixos-rebuild` you can add ‘foobar-1.2.3’ to
       `nixpkgs.config.permittedInsecurePackages` in the configuration.nix,
       like so:

         {
           nixpkgs.config.permittedInsecurePackages = [
             "foobar-1.2.3"
           ];
         }

    b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
    ‘foobar-1.2.3’ to `permittedInsecurePackages` in
    ~/.config/nixpkgs/config.nix, like so:

         {
           permittedInsecurePackages = [
             "foobar-1.2.3"
           ];
         }

Adding either of these configurations will permit this specific
version to be installed. A third option also exists:

  NIXPKGS_ALLOW_INSECURE=1 nix-build ...

though I specifically avoided having a global file-based toggle to
disable this check. This way, users don't disable it once in order to
get a single package, and then don't realize future packages are
insecure.

nixpkgs: allow packages to be marked insecure
If a package's meta has `knownVulnerabilities`, like so:

    stdenv.mkDerivation {
      name = "foobar-1.2.3";

      ...

      meta.knownVulnerabilities = [
        "CVE-0000-00000: remote code execution"
        "CVE-0000-00001: local privilege escalation"
      ];
    }

and a user attempts to install the package, they will be greeted with
a warning indicating that maybe they don't want to install it:

    error: Package ‘foobar-1.2.3’ in ‘...default.nix:20’ is marked as insecure, refusing to evaluate.

    Known issues:

     - CVE-0000-00000: remote code execution
     - CVE-0000-00001: local privilege escalation

    You can install it anyway by whitelisting this package, using the
    following methods:

    a) for `nixos-rebuild` you can add ‘foobar-1.2.3’ to
       `nixpkgs.config.permittedInsecurePackages` in the configuration.nix,
       like so:

         {
           nixpkgs.config.permittedInsecurePackages = [
             "foobar-1.2.3"
           ];
         }

    b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
    ‘foobar-1.2.3’ to `permittedInsecurePackages` in
    ~/.config/nixpkgs/config.nix, like so:

         {
           permittedInsecurePackages = [
             "foobar-1.2.3"
           ];
         }

Adding either of these configurations will permit this specific
version to be installed. A third option also exists:

  NIXPKGS_ALLOW_INSECURE=1 nix-build ...

though I specifically avoided having a global file-based toggle to
disable this check. This way, users don't disable it once in order to

cross stdenv: let build package's build deps resolve to native packages
2017-02-05 17:41:31 -05:00
John Ericson 5eaea6cee0 cross stdenv: let build package's build deps resolve to native packages
This fixes the "sliding window" principle:
  0. Run packages:       build = native;  host = foreign; target = foreign;
  1. Build packages:     build = native;  host = native;  target = foreign;
  2. Vanilla packages:   build = native;  host = native;  target = native;
  3. Vanilla packages:   build = native;  host = native;  target = native;
  n+3. ...

Each stage's build dependencies are resolved against the previous stage,
and the "foreigns" are shifted accordingly. Vanilla packages alone are
built against themsevles, since there are no more "foreign"s to shift away.

Before, build packages' build dependencies were resolved against
themselves:
  0. Run packages:       build = native;  host = foreign; target = foreign;
  1. Build packages:     build = native;  host = native;  target = foreign;
  2. Build packages:     build = native;  host = native;  target = foreign;
  n+2. ...

This is wrong because that principle is violated by the target
platform staying foreign.

This will change the hashes of many build packages and run packages, but
that is OK. This is an unavoidable cost of fixing cross compiling.

The cross compilation docs have been updated to reflect this fix.

Tuomas Tynkkynen c909f1b18e stdenv: Add updateAutoconfGnuConfigScriptsHook for aarch64
This is required for Aarch64 since a lot of source tarballs ship with
outdated configure scripts that don't recognize aarch64. Simply
replacing the config.guess and config.sub with new versions from
upstream makes them build again.

This same approach is used by at least Buildroot and Fedora. In
principle this could be enabled for all architectures but
conditionalizing this on aarch64 avoids a mass rebuild on x86.

The long term goal is a big replace:

And additionally making sure each is defined even when not cross compiling.

This commit refactors the bootstrapping code along that vision, but leaves
the old identifiers with their null semantics in place so packages can be
modernized incrementally.

John Ericson bf17d6dacf top-level: Introduce buildPackages for resolving build-time deps
[N.B., this package also applies to the commits that follow it in the same
PR.]

In most cases, buildPackages = pkgs so things work just as before. For
cross compiling, however, buildPackages is resolved as the previous
bootstrapping stage. This allows us to avoid the mkDerivation hacks cross
compiling currently uses today.

To avoid a massive refactor, callPackage will splice together both package
sets. Again to avoid churn, it uses the old `nativeDrv` vs `crossDrv` to do
so. So now, whether cross compiling or not, packages with get a `nativeDrv`
and `crossDrv`---in the non-cross-compiling case they are simply the same
derivation. This is good because it reduces the divergence between the
cross and non-cross dataflow. See `pkgs/top-level/splice.nix` for a comment
along the lines of the preceding paragraph, and the code that does this
splicing.

Also, `forceNativeDrv` is replaced with `forceNativePackages`. The latter
resolves `pkgs` unless the host platform is different from the build
platform, in which case it resolves to `buildPackages`. Note that the
target platform is not important here---it will not prevent
`forcedNativePackages` from resolving to `pkgs`.

--------

Temporarily, we make preserve some dubious decisions in the name of preserving
hashes:

Most importantly, we don't distinguish between "host" and "target" in the
autoconf sense. This leads to the proliferation of *Cross derivations
currently used. What we ought to is resolve native deps of the cross "build
packages" (build = host != target) package set against the "vanilla
packages" (build = host = target) package set. Instead, "build packages"
uses itself, with (informally) target != build in all cases.

This is wrong because it violates the "sliding window" principle of
bootstrapping stages that shifting the platform triple of one stage to the
left coincides with the next stage's platform triple. Only because we don't
explicitly distinguish between "host" and "target" does it appear that the
"sliding window" principle is preserved--indeed it is over the reductionary
"platform double" of just "build" and "host/target".

Additionally, we build libc, libgcc, etc in the same stage as the compilers
themselves, which is wrong because they are used at runtime, not build
time. Fixing this is somewhat subtle, and the solution and problem will be
better explained in the commit that does fix it.

Commits after this will solve both these issues, at the expense of breaking
cross hashes. Native hashes won't be broken, thankfully.

--------

Did the temporary ugliness pan out? Of the packages that currently build in
`release-cross.nix`, the only ones that have their hash changed are
`*.gcc.crossDrv` and `bootstrapTools.*.coreutilsMinimal`. In both cases I
think it doesn't matter.

 1. GCC when doing a `build = host = target = foreign` build (maximally
    cross), still defines environment variables like `CPATH`[1] with
    packages.  This seems assuredly wrong because whether gcc dynamically
    links those, or the programs built by gcc dynamically link those---I
    have no idea which case is reality---they should be foreign. Therefore,
    in all likelihood, I just made the gcc less broken.

 2. Coreutils (ab)used the old cross-compiling infrastructure to depend on
    a native version of itself. When coreutils was overwritten to be built
    with fewer features, the native version it used would also be
    overwritten because the binding was tight. Now it uses the much looser
    `BuildPackages.coreutils` which is just fine as a richer build dep
    doesn't cause any problems and avoids a rebuild.

So, in conclusion I'd say the conservatism payed off. Onward to actually
raking the muck in the next PR!

Nicolas B. Pierron da8cf2662a Fix missing overlays argument in stdenv/linux/default.nix 2017-01-16 01:17:33 +01:00
Nicolas B. Pierron f5dfe78a1e Add overlays mechanism to Nixpkgs.
This patch add a new argument to Nixpkgs default expression named "overlays".

By default, the value of the argument is either taken from the environment variable `NIXPKGS_OVERLAYS`,
or from the directory `~/.nixpkgs/overlays/`.  If the environment variable does not name a valid directory
then this mechanism would fallback on the home directory.  If the home directory does not exists it will
fallback on an empty list of overlays.

The overlays directory should contain the list of extra Nixpkgs stages which would be used to extend the
content of Nixpkgs, with additional set of packages.  The overlays, i-e directory, files, symbolic links
are used in alphabetical order.

The simplest overlay which extends Nixpkgs with nothing looks like:

```nix
self: super: {
}
```

More refined overlays can use `super` as the basis for building new packages, and `self` as a way to query
the final result of the fix-point.

An example of overlay which extends Nixpkgs with a small set of packages can be found at:
  https://github.com/nbp/nixpkgs-mozilla/blob/nixpkgs-overlay/moz-overlay.nix

To use this file, checkout the repository and add a symbolic link to
the `moz-overlay.nix` file in `~/.nixpkgs/overlays` directory.
