i don't know if the 'makefile may have been created in buildPhase' is
true but i guess it might be possible
This change allows building new gcc during bootstrap without fear of
pulling in outdated libstdc++.so after g++ switched from bootstrapTools
to freshly built g++.
Noticed when tried to add early bootstrap stage to rebuild `gcc` before
`glibc` is fully untangled from `bootstrapTools` as a failure to built
`binutils`:
ld: dwp.o: in function `__gnu_cxx::new_allocator<gold::Dwp_output_file::Contribution>::allocate(unsigned long, void const*)':
/nix/store/...-gcc-11.3.0/include/c++/11.3.0/ext/new_allocator.h:116: undefined reference to `std::__throw_bad_array_new_length()'
The change survives existing bootstrap and unblockes early `gcc` bootstrap.
Just a few comments added:
- added a few one-liners to explore which tools are rebuilt at each
stdenv iteration during bootstrap
- explicitly listed available toolchains and their sources for on each
bootstrap step: glibc, binutils, gcc, coreutils.
- added mention of static libraries linked into gcc

The documentation for `meta.sourceProvenance` in
`doc/stdenv/meta.chapter.md` says: "the `meta.sourceProvenance`
attribute should be a list containing one or more value..."
Let's update check-meta.nix to require that `meta.sourceProvenance` is
a list, as the documentation says, rather than a single element.
Adding two extra keystrokes `[` and `]` when filling out this field is
an insignificant burden for package authors, and being able to assume
that the `meta.sourceProvenance` field is always a list greatly
simplifies any code that acts on the value of this field.
Since `meta.sourceProvenance` was just merged a few hours ago now is
the easiest time to fix this: nobody is using the feature yet.
Without the change we don't propagate `enableParallelBuilding = true`
and leave most builds sequential.
Noticed on `mythtv` package which did not specify parallelism and
`config.enableParallelBuildingByDefault = true` had no effect.
Derivations not using `__structuredAttrs` should not attempt to set
environment variables from `env`.
Derivations using `__structuredAttrs` should fail if `env` is not
exportable.

This is needed in order to mark a certain derivation containing a Nix
expression tarball to Hydra so that it is recognised as a channel.
When I first got an evaluation error due to using this meta attribute, I
was under the impression that nobody outside of Vuizvui[1] is using this
feature and that we don't have any occurrence of isHydraChannel in
Nixpkgs.
However, when working around[2] the issue I assumed that it's not
something that should be included in Nixpkgs because we're not using it
there.
It turned out that my assumption was wrong and we *do* use the attribute
in Nixpkgs, namely via releaseTools.channel, which is similar to what
we're doing in Vuizvui.
Since we already include a bunch of undocumented attributes in
metaTypes, it only makes sense to add isHydraChannel as well since it's
actually documented in the Hydra documentation[3].

Passing `-l$NIX_BUILD_CORES` improperly limits the overall system load.
For a build machine which is configured to run `$B` builds where each
build gets `total cores / B` cores (`$C`), passing `-l $C` to make will
improperly limit the load to `$C` instead of `$B * $C`.
This effect becomes quite pronounced on machines with 80 cores, with
40 simultaneous builds and a cores limit of 2. On a machine with this
configuration, Nix will run 40 builds and make will limit the overall
system load to approximately 2. A build machine with this many cores
can happily run with a load approaching 80.
A non-solution is to oversubscribe the machine, by picking a larger
`$C`. However, there is no way to divide the number of cores in a way
which fairly subdivides the available cores when `$B` is greater than
1.
There has been exploration of passing a jobserver in to the sandbox,
or sharing a jobserver between all the builds. This is one option, but
relatively complicated and only supports make. Lots of other software
uses its own implementation of `-j` and doesn't support either `-l` or
the Make jobserver.
For the case of an interactive user machine, the user should limit
overall system load using `$B`, `$C`, and optionally systemd's
cpu/network/io limiting features.
Making this change should significantly improve the utilization of our
build farm, and improve the throughput of Hydra.
Stdenv on aarch64-darwin pulls in (bootstrap-stage4) objc4, unlike
x86_64. However derivations that otherwise depend on objc4 would use a
a different objc4 derivation on top of the final stdenv.
Because this library defines an LLVM module, having multiple instances
of it in the import path will interfere with builds.
This PR provides the Hydra-generated bootstrap tarballs for mips64el-linux-gnuabin32.
With this PR we now have the bootstrap-file for all three little-endian ABIs on mips: n64, n32, and o32. I do not currently plan to do big-endian mips unless some motivation arises; all mips chips are bi-endian and Debian has dropped big-endian support due to lack of interest.
I'll be following the script used in #151399, #168199, and #183487.
Files came from [this](https://hydra.nixos.org/build/188389586#tabs-summary) Hydra build, which used nixpkgs revision 97d9c84e1d to instantiate:

This is a change for `powerpc-linux` but that is ancient and I don't
think it matters. The impure bootstrap that was previously assigned to
it has probably bitrotted anyways.
Before the change an attempt to use `gnumake.override { guileSupport = true; }`
caused recursion in bootstrap stages as guileSupport pulls in guile and it's
dependencies.
To restore the bootstrap the change unconditionally sets
`guileSupport = false;` for `gnumake`.

Closes#178625
The `busybox` version of `mktemp` requires exactly six `X` characters
in the argument to `mktemp`, unlike the `coreutils` version of `mktemp`.
Let's accomodate packages, like `epson-escpr2`, which fool `setup.sh`
into using the `busybox` version instead of the `stdenv` version.
In 5643714dea, I changed pkgs/stdenv/linux/make-bootstrap-tools.nix
to take a package set instead of system and localSystem arguments, but
I forgot to update make-bootstrap-tools-cross.nix.

Since 97c43828fb the `file` package has

During stdenv bootstrapping, coreutils is built twice. This makes
troubleshooting very difficult, because both packages have
name="coreutils", so it is a hassle to figure out "which coreutils am
I using / is not building"?
The first of these builds is used only in stage4, and is not part of
the final stdenv. Let's label that one with a different `name`
attribute to make it obvious which is which.
The usage of `makeStaticLibraries` in stdenv/linux/default.nix is
prefaced by this comment:
# Link GCC statically against GMP etc. This makes sense because
# these builds of the libraries are only used by GCC, so it
# reduces the size of the stdenv closure.
However "these builds of the libraries are only used by GCC" is not
actually true. As currently written, the stage4 coreutils links
against these customized, static-ified libraries.
Beside the fact that the code doesn't actually do what it says, this
causes other problems as well. One example is #168983, which arises
because have a dynamically-linked binary (coreutils) which is built
from statically-linked libraries (libgmp.a); doing this causes mayhem
on platforms where `-fstack-protector` needs an auxiliary
`libssp.{so,a}` library; we end up with link failures because some
parts of the resulting binary want `libssp.so` and other parts want
`libssp_nonshared.a`.
Let's make the code actually do what the comment says, by moving these
definitions into the `gcc-unwrapped` override. This will cause the
stage4-coreutils to link against libgmp dynamically, rather than
statically. For this reason this commit depends on the previous
commit, which allows that to be done without creating a forbidden
reference from stdenv-final to the bootstrap-files.
As explained in the comment, this ensures that stage4-coreutils does
not leak a reference to the bootstrap-files by way of libgmp. This
will allow the next patch in this series to build stage4-coreutils
using a dynamically-linked (rather than statically-linked) libgmp.
It's expected that attributes in the top-level package set will all use
that package set, but this wasn't the case for the bootstrap tools.
This led some very confusing behaviour:
- pkgsMusl.stdenvBootstrapTools would build glibc bootstrap tools
- stdenvBootstrapTools was _always_ cross compiled, even if
Nixpkgs wasn't, because it always set crossSystem. This also didn't
match the behaviour of using make-bootstrap-tools.nix as an
entrypoint, where crossSystem would default to null.
For the Linux stdenv, I've made the ideal fix, which is to make pkgs an
argument rather than taking the arguments for pkgs, and then
re-importing it. This means it'll always use exactly the same package
set that's calling it, and should also mean faster eval due to not
importing Nixpkgs twice.
The Darwin stdenv is more complicated, and I'm not able to easily test
it, so I wasn't confident in making the same fix there. Instead, I've
just made sure crossSystem and localSystem are set to the correct values
so they're not always cross compiled and match the parent package set's.
It would still be preferable if somebody could make Darwin's
make-bootstrap-tools.nix take pkgs as an argument, rather than all the
arguments for pkgs.
it may be what the license handling code does, but it's confusing and not very useful

libtool's libtool.m4 script assumes that `file` is available, and can
be found at `/usr/bin/file` (this path is hardwired). Furthermore,
the script with this assumption is vendored into the ./configure
scripts of an enormous number of packages. Without this commit, you
will frequently see errors like this during the configurePhase with
the sandbox enabled:
./configure: line 9595: /usr/bin/file: command not found
Due mostly to luck, this error does not affect native compiles on
nixpkgs' two most popular platforms, x86_64-linux and aarch64-linux.
However it will cause incorrect linker flag detection and a failure to
generate shared libraries for sandboxed cross-builds to a x86_64-linux
host as well as any sandboxed build (cross or native) for the following
hosts: x86_64-freebsd, *-hpux, *-irix, mips64*-linux, powerpc*-linux,
s390x-linux, s390x-tpf, sparc-linux, and *-solaris.
This commit fixes the problem by adding an extra line to fixLibtool()
in pkgs/stdenv/generic/setup.sh. This extra line will scan the
unpacked source code for executable files named "configure" which
contain the following text:
'GNU Libtool is free software; you can redistribute it and/or modify'
This text is taken to be an indicator of a vendored libtool.m4. When
it is found, the configure script containing it is subjected to `sed
-i s_/usr/bin/file_file_` which replaces all occurrences of
`/usr/bin/file` with `file`.
Additionally, the `file` package is now considered to be part of
`stdenv`. It has been added to `common-path.nix` so that the `file`
binary will be found in the `$PATH` of every build, except for the
bootstrap-tools and the first few stages of stdenv boostrapping.

enable Hydra to produce bootstrap-files for mips64el:
nix-build \
--option sandbox true \
--option sandbox-fallback false \
pkgs/top-level/release-cross.nix \
-A bootstrapTools.mips64el-linux-gnuabi64.build
nix-build \
--option sandbox true \
--option sandbox-fallback false \
. \
-A pkgsCross.mips64el-linux-gnuabi64.nix_2_4
Instead of requiring the platforms be equal, use `isCompatible` to
determine if we can execute tests. The upside of this is that we now
can execute tests for natively cross compiled package sets like
pkgsStatic, pkgsLLVM and pkgsCross.musl64 etc.
canExecute is like isCompatible, but also checks that the Kernels are
_equal_, i.e. that both platforms use the same syscall interface. This
is crucial in order to actually be able to execute binaries for the
other platform.
isCompatible is dropped, since it has changed semantically and there's
no use case left in nixpkgs.
the motivation for this is to simplify stdenv and ease the job of
reviewers due to them needing to tell contributors about the defacto
rule that configureFlags should be a list of strings
stdenv: deprecate addCoverageInstrumentation adapter
this used to be used in nixos/tests but it hasn't been used in nixpkgs
for years
stdenv: deprecate replaceMaintainersField adapter
it was added in 2009 in 01e98e49b1
by nbp
there are no uses of it in nixpkgs now
stdenv: deprecate validateLicenses adapter
it was added in 2009 in b29073af25
unfreePredicate is now handled in ./pkgs/stdenv/generic/check-meta.nix
so this is unnecessary
This warning logs when a package has no maintainers. It will stay silent
if `meta.maintainers` is not set at all, only complaining when it is an
empty list. In the future a separate warning could be added to allow for
that stricter behavior. Or this warning could be changed.
This will allow for adding more validity types in the future, such as a
warning type. (which is in the next commit in this series)
This is NOT a breaking change because validity.valid is never exposed
outside of `stdenv.mkDerivation`.
This PR adds Hydra-generated bootstrap tarballs for powerpc64le-linux.
I'll be following the script established in PR to tarballs.nixos.org.
Files came from this Hydra build:
https://hydra.nixos.org/build/172142499
Which used nixpkgs revision 49a83445c2
to instantiate:
/nix/store/gj272sd56gsj6qpyzh4njpfzwdhviliz-stdenv-bootstrap-tools-powerpc64le-unknown-linux-gnu.drv
and then built:
/nix/store/n81pljbd8m0xgypm84krc2bnvqgjrfxx-stdenv-bootstrap-tools-powerpc64le-unknown-linux-gnu
I downloaded these files from Hydra with the following commands:
```
STOREPATH=n81pljbd8m0xgypm84krc2bnvqgjrfxx-stdenv-bootstrap-tools-powerpc64le-unknown-linux-gnu
OPTIONS="--option binary-caches https://cache.nixos.org"
nix store add-file \
--name bootstrap-tools.tar.xz \
$(nix-store ${OPTIONS} -r /nix/store/${STOREPATH})/on-server/bootstrap-tools.tar.xz
nix store add-path \
--name busybox \
$(nix-store ${OPTIONS} -r /nix/store/${STOREPATH})/on-server/busybox
```
As @lovesegfault requested in #151399, here are the the `sha256sum`s
of all the `on-server` components for extra verification:
```

This isn't really desirable in general, but given that Nix itself
currently relies on this behaviour and that we don't want to break
backwards compatibility we should support it for now, maybe
deprecating it in the future.
This reverts commit c1ef87e8d0.
I didn't realize that it would rebuild all linux stdenvs;
I certainly don't want to incur such a rebuild at this point.
At some point, I'd like to make another attempt at
71f1f4884b ("openssl: stop static binaries referencing libs"), which
was reverted in 195c7da07d. One problem with my previous attempt is
that I moved OpenSSL's libraries to a lib output, but many dependent
packages were hardcoding the out output as the location of the
libraries. This patch fixes every such case I could find in the tree.
It won't have any effect immediately, but will mean these packages
will automatically use an OpenSSL lib output if it is reintroduced in
future.
This patch should cause very few rebuilds, because it shouldn't make
any change at all to most packages I'm touching. The few rebuilds
that are introduced come from when I've changed a package builder not
to use variable names like openssl.out in scripts / substitution
patterns, which would be confusing since they don't hardcode the
output any more.
I started by making the following global replacements:
${pkgs.openssl.out}/lib -> ${lib.getLib pkgs.openssl}/lib
${openssl.out}/lib -> ${lib.getLib openssl}/lib
Then I removed the ".out" suffix when part of the argument to
lib.makeLibraryPath, since that function uses lib.getLib internally.
Then I fixed up cases where openssl was part of the -L flag to the
compiler/linker, since that unambigously is referring to libraries.
Then I manually investigated and fixed the following packages:
- pycurl
- citrix-workspace
- ppp
- wraith
- unbound
- gambit
- acl2
I'm reasonably confindent in my fixes for all of them.
For acl2, since the openssl library paths are manually provided above
anyway, I don't think openssl is required separately as a build input
at all. Removing it doesn't make a difference to the output size, the
file list, or the closure.
I've tested evaluation with the OfBorg meta checks, to protect against
introducing evaluation failures.
When implementing this reviewer request:
https://github.com/NixOS/nixpkgs/pull/161158#discussion_r822256070
to move mips64el-unknown-linux-* from platforms.nix to examples.nix, I
neglected to update the reference in make-bootstrap-tools-cross.nix.
As a result, the hydra jobs to generate a bootstrap tarball for
mips64el are not running:
https://hydra.nixos.org/eval/1750828?filter=mips&compare=1750620&full=#tabs-errors
This commit fixes the problem, so the hydra job can run. Once it
does, I will submit a PR adding the trusted bootstrap tarball hash to
pkgs/stdenv/linux/bootstrap-files/.

This change is prompted by the following, admittedly cursed tarball:
```
> curl https://registry.npmjs.org/char-regex/-/char-regex-1.0.2.tgz 2>/dev/null \
| tar -ztv
drw-rw-rw- 0/0 0 2020-02-18 10:50 package
-rw-rw-rw- 0/0 297 2020-02-18 10:50 package/index.d.ts
-rw-rw-rw- 0/0 1920 2020-02-18 10:50 package/index.js
-rw-rw-rw- 0/0 1092 2020-01-31 11:31 package/LICENSE

-rw-rw-rw- 0/0 713 2020-02-18 10:50 package/README.md
```
The minimal reproducer for the issue is the following derivation trying
to work around the uid 0 issue with `dontMakeSourcesWritable = true`:
```nix
{ stdenv, fetchurl }:
stdenv.mkDerivation {
name = "test";
src = fetchurl {
sha1 = "d744358226217f981ed58f479b1d6bcc29545dcf";
url = "https://registry.npmjs.org/char-regex/-/char-regex-1.0.2.tgz";
};
dontMakeSourcesWritable = true;
installPhase = ''
cp -R . $out
'';
}
```
This currently fails in the following way:
```
these derivations will be built:
/nix/store/pc3jbydl0xcc8nrndf5xkf7hdhpgpb41-test.drv
building '/nix/store/pc3jbydl0xcc8nrndf5xkf7hdhpgpb41-test.drv'...

error: build of '/nix/store/pc3jbydl0xcc8nrndf5xkf7hdhpgpb41-test.drv' failed
```
As you can see, the issue is that `$sourceRoot` isn't executable,
prohibiting the call to `cd`. This can be fixed by running
`chmod +x "${sourceRoot}"` before `cd` regardless of
`dontMakeSourcesWritable` in `unpackPhase` since if `chmod` fails, `cd`
would fail as well and we are out of options.
Verified that the workaround works locally.
Another thing to investigate is investigating if we should use
`--no-same-owner` for `tar` and if it helps in this case as well.

MIPS has a large space of {architecture,abi,endianness}; this commit
adds all of them to lib/systems/platforms.nix so we can be done with
it.
Currently lib/systems/inspect.nix has a single "isMips" predicate,
which is a bit ambiguous now that we will have both mips32 and mips64
support, with the latter having two ABIs. Let's add four new
predicates (isMips32, isMips64, isMips64n32, and isMips64n64) and
treat the now-ambiguous isMips as deprecated in favor of the
more-specific predicates. These predicates are used mainly for
enabling/disabling target-specific workarounds, and it is extremely
rare that a platform-specific workaround is needed, and both mips32
and mips64 need exactly the same workaround.
The separate predicates (isMips64n32 and isMips64n64) for ABI
distinctions are, unfortunately, useful. Boost's user-scheduled
threading (used by nix) does does not currently supports mips64n32,
which is a very desirable ABI on routers since they rarely have
more than 2**32 bytes of DRAM.
7459a40 `stdenv-bootstrap: force using new libc from stage2` overrode
`gcc-wrapper`. 91fa7657 `stdenv: revert gcc hack` dod not restore the initial
value.
As a result attempt to build glibc-2.35 fails early on perl as:
ld: cannot find -lnsl: No such file or directory
collect2: error: ld returned 1 exit status
I can't compile the test program.
(The supplied flags or libraries might be incorrect.)
The change restores `gcc-wrapper` as it was before 7459a40.
